Is it worth changing

Such changes in the electronic circuit of the chandelier will require a lot of effort, considerable time and financial costs. However, there are many benefits to be derived from this.

The service life of a halogen lamp is approximately 4000 hours, LED devices - 25-30 thousand hours. Add to this significant energy savings, which is achieved by reducing the power consumed by the chandelier, while maintaining the nominal intensity of the glow. If five 40 W halogens were installed, then the total load was 200 W. In the case of LED products, the load will be 7.5-10 watts. Thus, such a replacement is quite rational and justified. In order to save money, LED equipment is used in powerful spotlights installed in stadiums.

Above, we forgot to mention another important parameter that is taken into account when buying LED sources - color temperature. For the eyes, warm, yellow shades are much more pleasant, but the whiter the light, the more intense the luminous flux will be. Halogen lamps have approximately the same color temperature - about 2700 K (yellow glow), while for LEDs the range is much higher - from 2500 to 6500 K. As the color temperature rises, the glow becomes brighter and whiter.

Transformer for halogen lamps

All halogens are divided according to the operating voltage class - 220 volts and 12 volts. When replacing halogen lamps with g4 12v LED lamps, a transformer must be installed. It also additionally protects the lighting elements from power surges and overheating.

There are two types of transformers:

• Toroidal. Considered the simplest.It is assembled from a core and two windings. The main advantages are excellent reliability, simple connection, low price.
• Pulse (electronic). In its design, such a transformer has a core, two windings and a magnetic circuit. There are four types of electronic devices depending on the shape of the core and the method of locating the windings on it - armored, toroidal, rod and armored rod. In addition, pulse transformers differ in the number of turns of the windings. The main advantages of electronic transformers are compactness, light weight, large input voltage range, no noise and no heating during operation.

The pulse transformer has a high efficiency.

Which H4 halogen bulb is better to buy

Among the named nominees, each described H4 bulb has its own characteristics, strengths and weaknesses. This can make it difficult for the buyer to choose the right solution. It is worth relying on individual needs, budget, conditions of one's own comfort on the road. Based on the rating, several conclusions can be drawn:

• The brightest white light is Mtf-Light Argentum + 80% H4;
• The longest service life - Philips H4 LongLife EcoVision;
• The best ratio of quality and price - Osram Original Line H4;
• The best offer for bad weather is General Electric Extra Life;
• The lowest price is Narva H4 Standard.

For constant driving in the city, devices from the category with an extended service life are perfect

For the track, it is especially important to find that "halogen" that demonstrates a good near, long-range mode

If the driver has vision problems, you should pay attention to the category with improved visual comfort or increased brightness.LED devices are the undoubted leaders, but not everyone can afford such waste.

Calculation of transformer power for lamps and connection diagram

Various transformers are sold today, so there are certain rules for selecting the required power. Do not take a transformer too powerful. It will run almost idle. Lack of power will lead to overheating and further failure of the device.

You can calculate the power of the transformer yourself. The problem is rather mathematical and within the power of every novice electrician. For example, you need to install 8 spot halogens with a voltage of 12 V and a power of 20 watts. The total power in this case will be 160 watts. We take with a margin of 10% approximately and acquire a power of 200 watts.

Scheme No. 1 looks something like this: there is a single-gang switch on line 220, while the orange and blue wires are connected to the transformer input (primary terminals).

On the 12 volt line, all lamps are connected to a transformer (to the secondary terminals). The connecting copper wires must necessarily have the same cross section, otherwise the brightness of the bulbs will be different.

Another condition: the wire connecting the transformer to the halogen lamps must be at least 1.5 meters long, preferably 3. If you make it too short, it will start to heat up and the brightness of the bulbs will decrease.

Scheme No. 2 - for connecting halogen lamps. Here you can do it differently. Break, for example, six lamps into two parts. For each, install a step-down transformer. The correctness of this choice is due to the fact that if one of the power supplies breaks down, the second part of the fixtures will still continue to work. The power of one group is 105 watts.With a small safety factor, we get that you need to purchase two 150-watt transformers.

Advice! Power each step-down transformer with your own wires and connect them in the junction box. Leave the connections free.

The main types of halogen lamps

Depending on the appearance and method of application, halogen lamps are divided into several main types:

• with an external flask;
• capsular;
• with reflector;
• linear.

With external flask

With a remote or external bulb, a halogen lamp is no different from standard Ilyich bulbs. They can be connected directly to a 220 volt network and have any shape and size. A distinctive feature is the presence in a standard glass bulb of a small halogen bulb with a bulb made of heat-resistant quartz. Halogen lamps with a remote bulb are used in various lamps, chandeliers and other lighting devices with an E27 or E14 base.

Capsule

Capsular halogen lamps are miniature in size and are used to organize interior lighting. They have low power and are often used with sockets G4, G5 in a 12 - 24 volt DC network and G9 in a 220 volt AC network.

Structurally, such a lamp has a filament body located in a longitudinal or transverse plane, and a reflective substance is applied on the rear wall of the bulb. Such devices, due to their low power and size, do not require a special protective bulb and can be mounted in open-type luminaires.

With reflector

Reflector devices are designed to emit light in a directed manner. Halogen lamps may have an aluminum or interference reflector. The most common of these two options is aluminum.It redistributes and focuses the heat flux and light radiation forward, due to which the light flux is directed to the desired point, and excess heat is removed, protecting the space and materials around the lamp from overheating.

The interference reflector conducts heat inside the lamp. Halogen reflector lamps come in a variety of shapes and sizes, as well as different light emission angles.

Linear

The oldest type of halogen lamp, which has been used since the mid-60s of the 20th century. Linear halogen lamps look like an elongated tube, at the ends of which there are contacts. Linear lamps come in various sizes as well as high wattage, and are mainly applied to various spotlights and street lighting fixtures.

Halogen lamps with IRC coating

IRC-halogen lamps are a special kind of this kind of lighting devices. IRC stands for "infrared coverage". They have a special coating on the flask that freely transmits visible light, but prevents the passage of infrared radiation. The composition of the coating directs this radiation back to the filament, which increases the efficiency and efficiency of the halogen lamp, improves the uniformity of the glow and light output.

The use of IRC technology makes it possible to reduce the consumption of electrical energy by such devices by up to 50% and significantly affects the energy efficiency of the lighting device. Another advantage is the increase in service life by almost 2 times, in comparison with standard halogen lamps.

Halogen chandeliers

Halogen chandeliers are one-piece devices that are based on many halogen lamps connected in parallel to each other.Such chandeliers have a completely different appearance and configuration, and due to the small size of halogen lamps, they have an aesthetic appearance and a uniform glow.

In stores, you can find halogen chandeliers powered by 220 volts AC, as well as low-voltage options for use in DC systems or using with power supplies.

Do-it-yourself power supply alteration

For the operation of halogen lamps, pulsed current sources with high-frequency voltage conversion began to be used. When home-made and adjusted, expensive transistors quite often burn out. Since the supply voltage in the primary circuits reaches 300 volts, very high requirements are placed on insulation. All these difficulties can be completely circumvented by adapting a ready-made electronic transformer. It is used to power 12-volt halogen lights in the backlight (in stores), which are powered by a standard electrical outlet.

There is a certain opinion that getting a homemade switching power supply is a simple matter. You can only add a rectifier bridge, a smoothing capacitor and a voltage regulator. In fact, everything is much more complicated. If you connect an LED to the rectifier, then when you turn it on, you can fix only one ignition. If you turn off and turn on the converter in the network again, another flash will repeat. In order for a constant glow to appear, it is necessary to bring an additional load to the rectifier, which, taking away useful power, would turn it into heat.

One of the options for self-manufacturing of a switching power supply

Described power supply it is quite possible to make from an electronic transformer with a power of 105 watts.In practice, this transformer resembles a compact switching voltage converter. For assembly, you will additionally need a matching transformer T1, a surge protector, a rectifier bridge VD1-VD4, an output choke L2.

Such a device functions stably for a long time with a low-frequency amplifier with a power of 2x20 watts. At 220 V and a current of 0.1 A, the output voltage will be 25 V, with an increase in current to 2 amperes, the voltage drops to 20 volts, which is considered normal operation.

The current, bypassing the switch and fuses FU1 and FU2, follows the filter that protects the circuit from interference of the pulse converter. The middle of the capacitors C1 and C2 is connected to the shielding casing of the power supply. Then the current enters the input U1, from where the low voltage is supplied from the output terminals to the matching transformer T1. An alternating voltage from the other (secondary winding) rectifies the diode bridge and smoothes the L2C4C5 filter.

Self assembly

Transformer T1 is manufactured independently. The number of turns on the secondary winding affects the output voltage. The transformer itself is made on a K30x18x7 ring magnetic circuit made of M2000NM grade ferrite. The primary winding consists of a PEV-2 wire with a diameter of 0.8 mm, folded in half. The secondary winding consists of 22 turns of PEV-2 wire folded in half. When connecting the end of the first half-winding with the beginning of the second, we obtain the midpoint of the secondary winding. We also make the throttle ourselves. It is wound on the same ferrite ring, both windings contain 20 turns each.

Smoothing capacitors C4 and C5 consist of three K50-46 connected in parallel with a capacity of 2200 microfarads each.This method is used to reduce the overall inductance of electrolytic capacitors.

It would be better to install a surge protector at the input of the power supply, but it is possible to work without it. For the mains filter choke, you can use DF 50 Hz.

All parts of the power supply are surface-mounted on a board made of insulating material. The resulting structure is placed in a shielding casing made of thin sheet brass or tin-plated sheet. Do not forget to drill holes in it for air ventilation.

A properly assembled power supply does not need to be adjusted and starts working immediately. But just in case, you can check its performance by connecting a resistor with a resistance of 240 ohms to the output, with a dissipation power of 3 watts.

Step-down transformers for halogen lamps generate a very large amount of heat during operation. Therefore, several requirements must be met:

1. It is forbidden to connect the power supply without load.
2. Place the unit on a non-combustible surface.
3. The distance from the block to the light bulb is at least 20 centimeters.
4. For better ventilation, install the transformer in a niche with a volume of at least 15 liters.

A power supply is required for 12 volt halogen lamps. It is a kind of transformer that lowers the input 220 V to the desired values.

Advantages and disadvantages of 12V lighting

To switch to lighting devices that are connected to a low-voltage power source, you should study their advantages and disadvantages. Among the advantages are the following:

• Safety. The use of LED lamps in 12V fixtures increases the level of protection and eliminates the possibility of electric shock.
• Fire safety. Low-voltage wiring cannot be a source of ignition and cause a fire. Therefore, the wires do not need additional protection, they are not placed in corrugated sleeves.
• Versatility. An electric current whose voltage does not exceed 12 V is considered conditionally safe, which cannot cause serious damage to a person.In this regard, these lamps can be used in rooms with normal conditions and increased danger. For example, in sauna lights, cellar, bathroom, kitchen, bedroom, etc.
• Saving. When using this light source to illuminate the premises, it reduces energy consumption and, accordingly, the cost of money to pay bills.
• Environmental friendliness. The design does not use materials that, during the operation of the device, emit harmful substances to human or animal health.
• Reliability. The lamps are highly resistant to mechanical damage: scratches, chips, chipped, etc.

Despite all the advantages of the light source, it also has its drawbacks. The disadvantages of LED lamps designed for 12V include:

• An additional device is required - a power supply unit (PSU). The presence of a driver that stabilizes and lowers the mains voltage from 220 to 12 V complicates the wiring. It has its own efficiency, which reduces the efficiency of lighting and due to it an additional weak link appears in the circuit, which can fail.
• Glow brightness. The power of the luminous flux of a lamp connected to a low-voltage network is affected by a voltage drop. This is due to the high current consumption. Therefore, the length of the conductor from the transformer to the first and last light source must be the same, an error of 2 - 3% is allowed. Otherwise, the last lamp will shine dimmer than the first.

Wiring diagram for halogen lamps

Connecting halogen lamps
low voltage is carried out through special power supplies for 6, 12 and 24V.

It is noteworthy that low-voltage halogen lamps in practice turn out to be as bright as conventional ones, while energy consumption is reduced by an order of magnitude. In addition, low voltage acts as an additional guarantee of human safety.

Often these lamps are installed in bathrooms for safety reasons. However, low-voltage halogen lamps are also used in recessed ceiling luminaires, because the small size of modern electronic transformers allows them to be mounted directly on the frame of such ceilings.

The only limitation for the operation of such lamps is the need to install a special step-down transformer.

Fig 1. Connecting halogen lamps through a transformer

Thus, when a low-voltage halogen lamp is used for lighting
. the connection scheme to the network implies the presence of a 12V step-down transformer.

How to connect halogen lamps in the diagram

The very connection of the fixtures is extremely simple: for this it is enough to connect the halogen lamps in parallel with each other and connect them to the transformer.

Let us consider in more detail how all elements are connected to each other (transformer, halogen lamp wiring diagram and management).

The figure below shows a block diagram consisting of two step-down transformers and six halogen lamps. The neutral wire is marked in blue, the phase wire is in brown.

Connection on the side of 220 V. Connection of wires in the junction box is carried out in such a way that the phase of the supply wire (the one that comes into the box) goes to the switch.

Lighting control (on / off) is carried out by a conventional switch. It is connected to the transformers on the 220 V side.

The neutral conductor can be immediately connected to the neutral conductors of the wires that go to the transformers. After the phase wire that "came" from the switch is connected to the phase wires of the transformers.

To connect the wires in the transformer, special terminals L and N are provided.

Fig 2. Block diagram for connecting halogen lamps

It does not matter how many transformers will be connected in the circuit

It is important that each transformer is connected with a separate wire and all of them are connected only in the junction box. If you connect the wires not in a box, but somewhere under the ceiling, then if contact is lost, it will be impossible to get to the junction. Connection on the 12 V side

The main part of the work is done, only a little remains, connect the halogen lamp to the circuit
nutrition. The only thing to consider is that the halogen lamps in the circuit are connected in parallel with each other.

Connection on the 12 V side. Most of the work is done, only a little remains, connect the halogen lamp to the circuit
nutrition. The only thing to consider is that the halogen lamps in the circuit are connected in parallel with each other.

To connect a large number of lamps at the same time, it is worth using special terminal connectors. (The illustration uses six-track terminal blocks.)

To control the operation of all appliances in the house, including light sources, special devices are needed. We propose to consider what an electronic transformer for 12V halogen lamps is, its principle of operation, characteristics and video, how to connect the device yourself.

Varieties of halogen bulbs

Bulbs with halogens are classified according to power sources:

• low voltage version with 12 volt driver;
• incandescent lamps 220v.

The classification of lamps is shown in the figure below.

Low-voltage light bulbs can also be connected to a dedicated 220V power supply, but only with a step-down transformer. This device reduces the voltage to an acceptable level (12 volts). Halogen bulbs of this type have a pin base G4, G9, GU10, G12. Also in the automotive industry, a base type H4 is used.

The types of plinths are shown in the following figure.

Light bulbs are usually divided into several types depending on the features of their design:

• linear;
• capsular;
• with reflector;
• with a remote flask;
• low voltage;
• halogen chandeliers;
• IRC halogen light sources.

Linear

With this type of light bulbs, the production of halogen light sources began. Such lamps are produced to this day. The design of linear light sources has a pair of pin holders on both sides of the elongated bulb. For domestic purposes, such devices are rarely used because of their high power (from 1 to 20 kW).

Capsule

Such light bulbs are characterized by their small dimensions. Capsular light sources are used to illuminate interiors.G4 and G9 bases are usually used. As for the G9, this base is designed for a 220 V network. Due to their compactness and low power, capsule devices are often installed in open-type luminaires.

With reflector

Halogen lamps with reflectors are also referred to as directional lamps. A similar effect is achieved through the use of a reflector, which is performed in one of two options - interference or aluminum. In the case of an aluminum reflector, heat is dissipated to the front, while the interference design involves heat dissipation to the rear. Also, devices with a reflector are made with a protective cover and without it. Lamps with a reflector are equipped with different types of socles: for a 220 V network or low-voltage - for 12 Volts.

With extended flask

External bulb devices are often confused with standard incandescent bulbs. They have a similar design, including an E14 or E27 threaded base, the same glass bulb and filament. But there are halogens inside a bulb with a remote bulb.

Halogen chandeliers

Light sources of this type are produced with an E17 or E27 base. One of the main characteristics of chandeliers is the small size of the bulbs, they are almost invisible. Chandeliers are usually designed to operate from a 220 V network, however, there are also low-voltage lamps. In the latter case, you will need to connect through a step-down transformer.

Note! To avoid overheating, it is recommended to use ceramic cartridges instead of standard cartridges.

Low voltage

Low-voltage light sources include devices powered by 6, 12 or 24 volts. The most common option is a 12 volt lamp.Most often, low-voltage halogen bulbs are used when installed on flammable bases. They are used to illuminate interiors (spot lighting), small fragments of garden plots, to illuminate exhibits in museums, etc.

Due to their safety, low-voltage light sources are approved for use in rooms with a high level of humidity. But in this case, it is necessary to ensure reliable protection of the base from water ingress on it.

Note! Low voltage devices are always connected to the mains through transformers.

IRC halogen lamps

Halogen IRC lamps have a special coating that is transparent to visible light, but is a barrier to infrared radiation. This coating receives infrared light and reflects it back to the helix. This technology reduces heat loss and increases lamp efficiency. According to Orasm, the leading manufacturer, the technology reduces electricity consumption by 45% compared to other halogen bulbs. At the same time, the service life of the device is increased by 2 times. The IRC lamp allows you to get a powerful luminous flux - 1700 lm, as well as a light output of 26 lm / W, which is twice as high as a possible 35-watt fluorescent light source.

Conclusions and useful video on the topic

Video report on testing different G4 low voltage LEDs:

Overview of mini corn bulbs from Foton:

G4 LED luminaires are a worthy alternative to halogen bulbs. Their use can significantly reduce energy consumption, while maintaining high levels of illumination.

In order for the transition to LEDs to have exclusively positive aspects, it is necessary to carefully approach the choice of mini-lamps.
