Characteristics of LED Lamps

Ether Photoelectric Ltd | Updated: Apr 19, 2017

The ideal LED light source to replace the traditional light source, it has a wide range of uses. Summarize its ten features:

1. Energy saving: LED car lamp is a cold light source, the overall power consumption is low, consumes less than-W, more than 70%% of the traditional light source.

Second, environmental protection: The spectrum does not have ultraviolet and infra-red, neither heat nor radiation, glare, and waste recyclable, no pollution of mercury-free elements, can safely touch, belonging to a typical green lighting led source.

3. Long life: There is no loose part of the lamp body, there is no filament luminous, hot deposition, light failure, and other disadvantages, in the appropriate current and voltage, the service life can reach 6.1 million hours, than the traditional light source life longer than 10 times times.

Fourth, high brightness, high temperature resistance.

Fifth, small size.

6, stable performance, led seismic performance strong: Resin packaging, easy fragmentation, easily storage and transport.

7, luminous purity High, colorful, no shade filter light, light wave error within 10 nm.

8, the reaction speed, no heat start time, in microseconds can shine, traditional glass bulb has 0.3 seconds delay, can prevent rear-end collision.

The significance of limit parameters

(1) Allowable power LED consumption pm: Allow the led to the direct current DC voltage and flow through its current accumulation of the maximum value. Above this value, led fever, damage.

(2) Maximum positive DC current IFm: The maximum positive DC current allowed to be added. The diode can be corrupted by exceeding this value.

(3) Max reverse voltage VRM: Maximum allowable reverse voltage. Over this value, the LEDs may be damaged.

(LED4) Working environment TOPM: The luminous diode can work in ambient temperature range. Below or above the temperature range, the LEDs will not work properly, the efficiency is greatly reduced.
