Problems solved by technology

However, even in such a low traffic flow, street lighting maintains the brightness of the original lighting, instead of adjusting the lighting brightness as needed, which wastes power in vain.
The existing infrared sensing and Doppler sensing (radar sensing) have a short detection distance and are not suitable for controlling street lights

Abstract

The invention relates to a light modulation apparatus of an LED lamp. The light modulation apparatus comprises an LED lamp and an LED light source. The LED lamp at least includes a first LED lamp and a second LED lamp; the first LED lamp and the LED light source form a first loop; and the second LED lamp and the LED light source form a second loop. An image control signal that is outputted by a DSP or an ARM is arranged in the second loop. The LED light source contains a first LED power supply and a second LED power supply; the first LED lamp and the first LED power supply form a first loop; and the second LED lamp and the second LED power supply form a second loop. Besides, a unidirectional silicon controlled rectifier, a bidirectional silicon controlled rectifier, a photoelectric coupler, a light-coupling bidirectional silicon controlled rectifier, a triode, a relay and / or an MOS tube. The image control signal is connected with the unidirectional silicon controlled rectifier, the bidirectional silicon controlled rectifier, the photoelectric coupler, the light-coupling bidirectional silicon controlled rectifier, the triode, the relay or the MOS tube. The provided light modulation apparatus has characteristics of simple and reasonable structure, flexible operation, and low energy consumption.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp dimming device. Background technique [0002] After 9 o'clock in the evening in small cities in my country, and after 12 o'clock in the middle of the night in large and medium-sized cities, the roads are almost empty. The situation, that is to say, there are fewer pedestrians or vehicles on the road at this time. However, even in such a low traffic flow, street lighting maintains the brightness of the original lighting, instead of adjusting the lighting brightness as needed, which wastes power in vain. The existing infrared sensing and Doppler sensing (radar sensing) have a short detection distance and are not suitable for controlling street lamps. [0003] Chinese patent document number CN 204127795 U disclosed a kind of adjustable spectrum light source for color image acquisition on January 28, 2015. The spectrum light-emitting unit, in which 7 LED light-emitting diodes use LEDs of ...
