Problems solved by technology

[0003] For urban lighting, the serious light decay of LED not only affects the landscape effect, but also reduces the service life of lamps and lanterns.
At present, most LED street lights use full-power lighting, and full-power lighting in the middle of the night not only speeds up the speed of LED light decay, but also consumes a lot of power
The above situation is not the main problem that causes the LED street lights to fade, but the most critical problem is the heat dissipation of a single lamp. If the working temperature of the LED is too high, it will inevitably accelerate the speed of its light decay. Traditional lamps are not very effective for heat dissipation through heat sinks. Solve the light decay speed of LED

Abstract

The invention discloses an LED street lamp intelligent control system. The LED street lamp intelligent control system comprises N LED lamps connected in parallel and a remote control device. Each LED lamp is internally provided with an LED light source, a branch controller, a temperature sensor and a branch voltage adjusting device. The branch control is connected with the temperature sensor and the branch voltage adjusting device. The temperature sensor is used for detecting the temperature in the LED lamp. The branch voltage adjusting device is used for adjusting an input voltage of the LED lamp. The remote control device comprises a total control and a total voltage adjusting device. The total controller is in communication with the branch controller in each LED lamp. The total controller is connected with the total voltage adjusting device and a time relay. The total voltage adjusting device is used for adjusting an output voltage of the total controller. According to the invention, the long service lifetime and the high light efficiency of each LED light source are ensured, the working current of each LED light source is gradually lowered in work, and the working power of each LED light source is gradually lowered, so that the working temperature of each LED lamp is lowered, and the light decay speed of each LED light source is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent control of LED street lamps, in particular to an intelligent control system of LED street lamps. Background technique [0002] With the widespread use of LEDs, LED light decay has also received attention. LED light decay means that after the LED is lit for a period of time, its light intensity will be lower than the original light intensity, and the lower part is the light decay of the LED. Generally, LED packaging manufacturers do the test under laboratory conditions (at room temperature of 25°C), continuously lighting the LED with 20mA DC for 1000 hours to compare the light intensity before and after lighting. [0003] For urban lighting, serious LED light decay not only affects the landscape effect, but also reduces the service life of the lamps. At present, most LED street lights use full-power lighting, and full-power lighting in the middle of the night not only speeds up the speed of L...
