For cars use, LED structure is a small chip is encapsulated in epoxy, in general, its operating voltage is 2-3.6V, the operating current is 0.02-0.03A, is a way to convert electrical energy into visible light semiconductor, it changed the incandescent tungsten light and energy-saving lamp base toner light principle, and use electric light. With long life, high luminous efficiency, radiation and energy-saving advantages. Its inherent characteristics it is the ideal light source to replace the traditional light source, it has a wide range of uses. what are led bulbs for cars? Due to the needs of the automobile exterior design, the aerodynamic requirements and aesthetic needs, as well as the concept of environmental protection, people will use LED lights in the instrument lights backlight display, front and rear turn lights, brake lights, reversing lights, fog lights, reading lamps and other functional aspects, but also have a decorative function, transformation to achieve glory.
what are led bulbs for cars? The good points of car led bulbs are listed below.
2. With enhanced seismic performance, because the LED is completely encapsulated in epoxy resin inside it than light bulbs and fluorescent tubes are sturdy.
3. high luminous purity, without shade filter, wavelength error of less than 10 nm.
4 small, light-emitting heat lamps materials, heat resistance requirements are not high.
5, Beam angel, easier to control, and do not need to reduce the depth of the lamp with reflector concentrator.
6. Low power consumption and energy utilization up to 80%, to reach the traditional light bulb the same brightness, power consumption is only 6% of the traditional light bulb, power-saving fuel economy.
7. Long life, the filament structure is not heat, no glass, tungsten and other vulnerable moving parts, the failure percentage is very low, maintenance-free under normal use within more than six years.
8. vehicle control circuit is not easily oxidized.
9. Small size and light weight. Various types of lamps can be designed to slim and compact car design space.
10 environmental protection and green lighting. No excess infrared, UV spectra of the LED spectrum, without mercury-containing hazardous substances, heat, radiation, more suited to the requirements of the green car.
Although the LED has been widely used in the car, but the LED is a multi-compound semiconductor components, electrical, optical, thermal and mechanical parameters of highly discrete. what are led bulbs? Therefore, the design should take full account of this characteristic, the components of automotive LED light source and led street light to strict classification, grading.
