What are halogen headlights? What s the difference with LED lights?

Halogen headlamps are a new generation of incandescent lamps, tungsten lamps filled with halogen elements such as bromine iodine or halides. In order to increase the luminous efficiency of incandescent lamps, the temperature of the tungsten filament must be increased, but the corresponding sublimation of tungsten will be caused and condensation on the glass shell to make it black. The incandescent lamp is filled with halogen elements or halides, and the principle of tungsten halogen circulation can be used to eliminate the blackening of the glass shell of the incandescent lamp.

1. Halogen lamps use tungsten filaments to emit light, and LED lamps use diodes to emit light.

2. Halogen lamps are generally 55 watts used in cars, and LED lights are about 20 watts.

Halogen headlamp refers to a tungsten lamp filled with halogen elements such as bromine and iodine or halides, which is called halogen lamp, which is a new generation of incandescent lamp. Halogen headlights** are much lower than LED headlights**. Because the cost of chemical halogen gas and tungsten filament and other materials used in halogen headlights is low, while the production materials of LED headlights are higher.

The service life of LED headlights can reach about 100,000 hours, compared with the average life of halogen headlight sources.

Halogen lamps use tungsten filaments to emit light, and LED lamps emit light from light-emitting diodes; The brightness halogen lamp is relatively low, 55W is more than 1000 lumens, while the LED headlights currently have 20W can reach 3000-4000 lumens.

1.The principle of luminescence is not the same.

Halogen lamps use tungsten filaments to emit light, xenon lamps emit light from inert gas discharges, and LED headlamps emit light from light-emitting diodes.

2.The energy consumption is different.

Halogen lamps consume the most energy, generally using 55W in cars, 35W for xenon lamps, and about 20W for LED headlights.

What are the advantages and disadvantages of halogen headlights and LED lights?

The ordinary headlights we are talking about are halogen headlights, and the LED lights are diodes, which have a smaller chance of damage and higher brightness, but if they are damaged, then the cost is also higher.

Now it is more respected LED headlights, which are relatively energy-saving and environmentally friendly, and have a long lifespan.

The difference between halogen headlights and LED headlights: different luminous principles, different energy consumption, different brightness, different service life, and different color temperatures.

1. The principle of luminescence is different

Halogen lamps use tungsten filaments to emit light, and LED lamps emit light from light-emitting diodes;

2. The energy consumption is different

Halogen lamps consume the most energy, generally using 55W in cars, and LED lights are about 20W.

3. The brightness is different

The brightness of halogen lamps is low, 55W is more than 1000 lumens, and some LED lamps can reach 3000-4000 lumens with 20W.

4. The service life is different

Generally, the service life of halogen lamps is 500 hours, and the service life of LED lamps can reach about 50,000 hours.

5. The color temperature is different

Halogen lamps generally have only one color temperature, the color temperature is about 2700K, and the light is yellowish. LED lights are generally 4300K or 6000K.

The difference is different:1. The principle of luminescence is different.

Halogen lamps use tungsten filaments to emit light, and LED headlamps emit light from light-emitting diodes.

2. The energy consumption is different

Halogen lamps consume the most energy, generally using 55W in cars, and LED headlights are about 20W.

3. There is a difference in brightness.

The halogen lamp 55W is more than 1000 lumens, and the LED headlights currently have 20W can reach 3000-4000 lumens.

4. The service life is different

Generally, the service life of halogen lamps is 500 hours, and the service life of LED headlights is not yet conclusive, because the current technology is not very mature, but the theory can reach about 50,000 hours.

5. Color temperature difference.

Halogen lamps generally only have one color temperature, the color temperature is about 2700K, and the light is yellowish, while LED headlights are generally 4300K or 6000K at present, and there may be more color temperatures to choose from in the future.

Halogen lamps emit yellow light, generate heat, strong penetration, insufficient brightness, high power consumption, short life, LED lamps emit white light, strong brightness, power consumption, long life, but white light penetration is weak and costly. Hope it helps.

The color of the halogen headlights is yellow, and the color of the LED headlights is white, so at night the LED headlights are better than the halogen light source, and you can see more clearly and farther.

In fact, for car lights, the pros and cons of halogen lamps and LED lamps are particularly obvious, the biggest difference is that halogen lamps have strong penetration, halogen lamps have strong penetration in rainy and foggy days, and the irradiation distance is farther than others; The advantages of LED lights are also obvious, with high brightness, and you can see more clearly when driving at night, but the effect is not very good in rainy and foggy days.

The production cost of halogen headlights is low, the penetration ability of the light is stronger than that of LED headlights, and the production cost of LED headlights is relatively high, which is energy-saving and power-saving, and has a long service life. The following are the differences between the two: 1. The brightness of halogen lamps is only more than 1000 lumens, and LED lamps can reach more than 3000 lumens.

LED lamps have a much longer service life than halogen lamps, with an average of 4 years of service and a maximum of 6 months for halogen lamps. The color temperature of halogen lamps is only 3400K, the color is yellowish, the illumination effect is not good, the color temperature of LED lamps ranges from 4000K-8000K, of which about 5500K is the best color temperature, the best for the human eye, and the color is white. Halogen lamps use tungsten filaments to emit light, and LED lamps emit light from light-emitting diodes;

2. The headlights of the car are the headlights of the car, which provide lighting conditions for the safe driving of the car when driving at night, when the brightness of the headlights is not enough, the headlights of the car can be used, the headlights of the cars adopt the method of scientific pressurization, provide constant working voltage for the headlights of the headlights, and when the bulb filament of the headlights is preheated and protected when starting, the headlights can emit a constant bright white light, so that the brightness does not change with the speed change of the engine, does not increase the load of the car, and is easy to install.

The main differences between LED headlights and halogen headlights: 1. The principle is different, halogen lamps use tungsten filament to emit light, and LED headlights are diode light; 2. The energy consumption is different, and the energy consumption of halogen lamps is much larger than that of LED lights; 3. The brightness is different, and the LED light is much brighter than the halogen light; 4. The service life is different, and the life of LED lamps is much longer than that of halogen lamps; 5. The color temperature is different, and the color temperature of the LED light is much larger than that of the halogen light.

1.The luminous principle is different: halogen lamps use tungsten filaments to emit light, and LED headlights emit light with light-emitting diodes. 2.

The energy consumption of halogen lamps is the largest, and the general car uses 55W, and the LED headlights are about 20W. 3.There is a difference in brightness, halogen lamp 55W is more than 1000 lumens, LED headlights currently have 20W can reach 3000-4000 lumens.

4.The service life of the general halogen lamp is 500 hours, and the service life of the LED headlamp is not yet conclusive, because the current technology is not very mature, but the theory can reach about 50,000 hours. 5.

Color temperature difference halogen lamps generally have only one color temperature, the color temperature is about 2700K, and the light is yellowish, while LED headlights are generally 4300K or 6000K at present, and there may be more color temperatures to choose from in the future.
