With the development of technology, LED car lights can provide a brighter and wider pavement effect at night and have gradually occupied the mainstream market. The most ideal LED light source to replace the traditional light source, it has a wide range of uses. The following are its three main features.

Energy-saving and environmental protection
RoundLED car lights are cold light sources, overall low power consumption, power consumption of no more than 70% energy saving than traditional light sources. Secondly, there is no ultraviolet and infrared light in the spectrum, neither heat nor radiation, glare is small. And the waste can be recycled, no pollution does not contain mercury elements. It can be safe to touch, belonging to the typical green lighting light LED source. There is no filament luminescence easy to burn, thermal deposition, light decay, and other shortcomings. In the appropriate current and voltage, the service life of up to 6-10 million hours, more than 10 times longer than the life of traditional light sources.
Its characteristics
Super bright LED car lights s high brightness, high-temperature resistance, and small size. It has good stability performance. Super Bright led car lights to have strong shock resistance because it is resin encapsulated, not easy to break, easy to store and transport. It has high luminous purity, vivid colors, no lampshade filtering, and lightwave error within 10nm. Its fast response time, no hot start time, microseconds to light, while the traditional glass housing bulbs have 0.3 seconds delay, which can prevent tailgating.
The significance of the limit parameters
(1) Allow the power of LED car lights consumption Pm. Allowed to add to the LED terminals forward DC voltage and the product of the current flowing through it the maximum value. Beyond this value, the LED heats up and is damaged.
(2) Maximum forward DC IFm: the maximum forward DC allowed to be added. Exceeding this value can damage the diode.
(3) The maximum reverse voltage VRm: the maximum reverse voltage allowed. Beyond this value, the light-emitting diode may be damaged by the breakdown.
The significance of electrical parameters
(1) Spectral distribution and peak wavelength: a light-emitting diode issued by the light is not a single wavelength.
(2) Luminous intensity IV: light-emitting diode luminous intensity is usually referred to as the direction of the normal LED line (for the cylindrical light-emitting tube is its axis) luminous intensity. If the radiation intensity is in the direction of (1/683) W / sr when the luminous 1 candela (symbol for cd). As a result of the general LED luminous two intensity is small, so the luminous intensity commonly used candela for the unit.
(3) Forward working voltage VF: the working voltage given in the parameter table is obtained at a given forward current. Generally, is measured at IF = 20mA. Light-emitting diode forward operating voltage VF in 1.4 ~ 3V. If the external temperature increases, VF will decline.
Round led car lights are extremely important to driving safety. According to relevant statistics, driving at night, 70% of accidents are caused by poor vision, the core of poor vision is because the lights are not bright enough. Poor vision, resulting in accident rates, danger, damage, and death and injury rates. Therefore, the importance of LED car lights on driving safety cannot be overstated!
