Abstract

The invention provides an automatic-control type light-emitting diode (LED) power supply which mainly solves the problem that work of a power supply in the prior art cannot be adjusted to be suitable for the environment to cause that the power supply is prone to be damaged. The automatic-control type LED power supply comprises a circuit board, a power supply box body and a power supply box cover, wherein the circuit board is fixedly arranged in the power supply box body. The power supply box body is in a U shape or an L shape and comprises a power supply box body lateral wall and a power supply box body bottom plate, the circuit board is fixedly arranged on the power supply box body bottom plate, and a control device for cutting off the power supply or reducing power supply power when power supply temperature is too high or humidity of environment where the power supply is arranged is too high is positioned on the circuit board. The control device additionally arranged in the automatic-control type LED power supply is used for cutting off the power supply or reducing power supply power when power supply temperature or humidity is too high so as to prevent the power supply from being damaged and prolong service life of the power supply.

Description

Technical field [0001] The invention relates to the field of LED lighting, in particular to a self-controlling LED power supply. Background technique [0002] The ideal LED is to use constant voltage and constant current. But the cost of the drive increases. In fact, each driving method has advantages and disadvantages. According to the requirements and application of LED products, reasonable selection of LED driving methods and precise design of the driving power supply become the key. Although LED is more efficient than ordinary light sources in terms of energy saving, LED light sources cannot directly use the public grid voltage like ordinary light sources. It must be equipped with special voltage conversion equipment to provide voltage and current that can meet the LED’s rating. The normal operation of the LED is the so-called dedicated LED source. [0003] None of the existing LED power supplies are provided with a control device, so that when the temperature or humidity is...
