Power supply device with cooling function capable of being integrated with LED chip

Abstract

The invention belongs to a power supply device with a cooling function capable of being integrated with an LED chip. The power supply device with the cooling function capable of being integrated with the LED chip is composed of a power supply shell with the cooling function, a drive power supply circuit board, an LED chip, an LED chip pedestal, an LED chip fixing plate, a power supply input end cover plate and the like and characterized in that the LED chip can be screwed and fixed on the power supply shell through an outer stud of the LED chip pedestal and an inner nut on the LED chip fixing plate at one side of the power supply shell. The power supply device with the cooling function capable of being integrated with the LED chip changes the traditional mounting structure that an LED lamp uses a shell as a body, a light source is integrated with a power supply, the light source can independently serve as the light source without the lamp, and moreover, the light source can be used in an array mode through combination; the power supply device with the cooling function capable of being integrated with the LED chip standardizes the matching performance requirement between single light source and the power supply, is good for standard production, enables the production cost to be lowered, enables the power of the single light source and power supply to be lowered, enables the heat of a single LED module to be lowered, enables the drive power supply structure to be simplified, and enables the service life of the power supply to be improved.

Description

technical field [0001] The invention belongs to a power supply device, in particular to a power supply device which can be integrated with an LED chip and has a heat dissipation function. Background technique [0002] LED chip is a light source with high luminous efficiency that needs to work in low-voltage DC mode. To use LED chip for lighting, the AC power supply provided for lighting that is higher than the working voltage of the LED chip must be converted from AC to DC. After the constant current measures, the LED chip can only work normally by providing a DC voltage and current that can match the work. Therefore, all current LED lighting fixture structures are composed of three parts: LED chip (illuminant is the light source), power supply (driving power supply) and lamp housing. Because the LED chip will generate heat when it is working, if it cannot effectively dissipate heat with the help of the lamp housing, the LED chip will fail due to temperature rise, so the LE...

AI Technical Summary

Problems solved by technology

[0003] LED chips can form countless specifications with working voltage from 3V to 300V and power from 3W to hundreds of W through different series, parallel or their combination, and need to have a matching power supply to work, so for the current LED lighting The product has a wide variety of specifications, and both the manufacturer and the user are confused, which is not conducive to the promotion and application of LED lamps and the reduction of production costs, and is also not conducive to the maintenance of LED lamps after installation and use.
