Characteristics of LED tail lights
The most ideal LED light source to replace traditional light sources has a wide range of applications. Summarize its ten characteristics:
1, Energy saving: LED car lights are cold light sources, which generally consume low power and do not exceed - W, saving more than 70% of energy compared to traditional light sources.
2, Environmental protection: There is no ultraviolet or infrared radiation in the spectrum, neither heat nor radiation, with low glare, and the waste is recyclable. There is no pollution or mercury element, and it can be safely touched. It is a typical green lighting LED source.
3, Long lifespan: There are no loose parts inside the lamp body, and there are no drawbacks such as easy burning of the filament, thermal deposition, and light decay. Under appropriate current and voltage, the lifespan can reach 60-100000 hours, which is more than 10 times longer than the lifespan of traditional light sources.
4, High brightness and high temperature resistance.
5, Small in size.
6, Good stability and strong seismic resistance of LED: resin encapsulated, not easy to break, easy to store and transport.
7, High luminous purity, bright colors, no need for lampshade filtering, light wave error within 10 nanometers.
8, Fast reaction speed, no need for hot start time, can emit light within microseconds, while traditional glass bulb has a delay of 0.3 seconds, which can prevent rear end collisions.
9, The significance of limit parameters
(1) Permissible power LED consumption Pm: The maximum value of the product of the forward DC voltage applied to both ends of the LED and the current flowing through it. Exceeding this value will cause LED heating and damage.
(2) Maximum forward DC current IFm: The maximum allowed forward DC current to be applied. Exceeding this value can damage the diode.
(3) Maximum reverse voltage VRm: The maximum allowed reverse voltage to be applied. Exceeding this value may cause breakdown and damage to the light-emitting diode.
(4) Top of the working environment: The temperature range within which the light-emitting diode can operate normally. Below or above this temperature range, the light-emitting diode will not function properly and its efficiency will be greatly reduced.
