Example Embodiment

[0059] The present invention will be further described below with reference to the drawings and embodiments.

[0060] See Figure 1-Figure 42 , The control device for a three-state LED lamp includes an LED lamp and an LED power supply. The LED lamp includes at least a first LED lamp and a second LED lamp. The LED power supply includes at least a first LED power supply and a second LED power supply. , The first LED light and the first LED power supply form the first loop, the time control signal is connected to the first loop, the second LED light and the second LED power supply form the second loop, and the image control signal is output through DSP, FPGA or ARM Connect with the second loop.

[0061] Among them, the first LED lamp can be one lamp or a group of lamps, and the same is true for the second LED lamp.

[0062] In this embodiment, the time control signal is connected to the first circuit through a unidirectional thyristor, a triac, a photocoupler, an optical coupling triac...

Abstract

A control device used for a tristate LED lamp comprises a LED lamp and a LED power supply. The LED lamp at least comprises a first LED lamp and a second LED lamp. The LED power supply at least comprises 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. A time control signal is connected to the first loop. The second LED lamp and the second LED power supply form a second loop. An image control signal output by a DSP, a FPGA or an ARM is connected to the second loop. The time control signal is connected to the first loop through a unidirectional silicon controlled rectifier, a bidirectional silicon controlled rectifier, a photoelectric coupler, an optical coupling bidirectional silicon controlled rectifier, a triode, a composite triode, a relay and/or a MOS pipe. The image control signal is connected to the second loop through the unidirectional silicon controlled rectifier, the bidirectional silicon controlled rectifier, the optoelectronic coupler, the relay and/or the MOS pipe. The device possesses characteristics that operation is flexible and energy consumption is low.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a control device for a three-state LED lamp. Background technique [0002] At present, urban street lamps basically use time controllers to control the on and off of street lamps. Due to the change of seasons, the time between dark and dawn changes gradually. If the lights are not turned off, it will cause inconvenience for people to travel or waste power. [0003] After 9:00 p.m. in small cities in my country, and after 12:00 midnight in large and medium-sized cities, the roads are almost empty. Even in the bustling cities like Beijing, Shanghai, and Guangzhou, there are fewer pedestrians and vehicles on the roads after 2:00 a.m. . When the traffic flow is low, the 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 dete...
