Description
Technical field
It is on a kind of car rump mobile LED steering indicating light the invention belongs to application of electronic technology field.
Background technology
Car rump mobile LED steering indicating light is made with LED, its brightness ratio ordinary incandescent lamp is high, and also
It is fast with reaction speed.It changes the luminous principle lighted with electricity-saving lamp tricolor powder of incandescent lamp tungsten filament.According to data introduction, hair
The features such as optical diode LED has luminous efficiency high, radiationless, low-power consumption and long lifespan, its luminous efficiency is up to 80~90%.
LED is contrasted with ordinary incandescent lamp, and its result shows：The luminous efficiency of ordinary incandescent lamp is only 12Lm/W,
