Circuit device of light-emitting diode (LED) drive stabilizing system

Abstract

The invention relates to a circuit device of a light-emitting diode (LED) drive stabilizing system, which mainly comprises an alternating current / direct current (AC / DC) controllable drive voltage source, a feedback drive controller, an LED modulation drive controller controllable drive voltage source and an LED assembly module device, wherein condition factors of the inner part are produced by integral or local set operation, and the outer part is connected with an input signal source according to characteristics of different attributes, thereby achieving the function of automatic adjustment so as to reduce the luminance brightness decay rate when the LED assembly module device is used for a long time, saving electric power loss and reducing the heat source production, and prolonging the service life of an LED.

Description

technical field [0001] The invention relates to a circuit device for driving and stabilizing a light-emitting diode (LED), in particular to a circuit device that can be externally connected to input signals according to the characteristics of different attribute conditions in addition to its internal conditions and factors being generated by overall or partial setting operations. Source, and then achieve the function of automatic adjustment, so that when the LED component module is used for a long time, it can reduce the brightness decay rate, save power loss and reduce heat generation, so the service life of the LED can be extended. Background technique [0002] With the rapid development of modern technology, LEDs are gradually replacing light bulbs and mercury-containing fluorescent tubes in the light source structure of commercially available lighting, mainly because LEDs have low power consumption, long component life, no need for warm-up time, fast response and It will...

Problems solved by technology

[0003] Nowadays, the light sources of LED lighting have achieved lighting effects of considerable brightness, but there are still several technical problems to be overcome. They are all committed to improving the efficiency of heat dissipation. Although the related technologies can effectively dissipate heat and avoid overheating, it is easy to cause waste of power supply to the LED, and after a long period of use, the brightness decay rate of the LED will gradually increase. Reduced service life

[0004] In addition, since the light source of LED lighting is used as a product, since it can only use direct current instead of alternating current as its power source, if LED is to be completely popularized or replace general household electrical lighting products, the problem is that it cannot be used like ordinary electrical appliances. The product can be used after being plugged into any ordinary socket, but a (AC / DC) AC to DC converter must be added, so it is inconvenient to use
