Matrix type modular LED (Light-emitting Diode) light source module

Abstract

The invention discloses a matrix type modular LED (Light-emitting Diode) light source module, which comprises a support bottom plate. Connecting seats are uniformly arranged on an upper surface of thesupport bottom plate and are connected with the support bottom plate through a welding way; two conductively connected jacks are welded to a bottom surface inside each connecting seat; support platesare arranged on the inner part of the upper end of the support bottom plate; two LED light source modules can be combined through clamping grooves and clamping columns, so that an installation and combination device is more convenient; LED light beads can be installed on the connecting seats through the connection of the conductive clamping columns and the conductively connected jacks, so that the LED light beads can be installed and replaced conveniently; the LED light beads can be thoroughly fixed through an upper end cover plate; and the device is faster to cool through a metal heat-radiating layer on the upper end cover plate. The matrix type modular LED light source module is simple in structure, not only can the light beads be replaced conveniently, but also the LED light source modules can be assembled conveniently, and a heat radiating effect is better.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a matrix modular LED light source module. Background technique [0002] LEDs (Light Emitting Diodes, light emitting diodes) can emit light when they are powered on; therefore, LEDs have been widely popularized and applied in the lighting field, such as LED street lamps, LED display screens, and the like. However, LED heating is an inherent chronic disease. During the working process of LEDs, only 20-30% of the electrical energy is converted into light, and the rest of the electrical energy is converted into heat energy. The heat causes the LED to produce light decay, which is the main cause of LED failure. The reason is that the service life of LED is greatly shortened. The heat dissipation problem is the biggest technical problem in the popularization and development of LED lighting devices; in LED lamps, the cost of heat dissipation accounts for a considerable part, and the v...

Problems solved by technology

Thermally conductive silicone grease is an insulating material, and the aluminum substrate also contains an insulating layer. The insulating material usually has a high thermal resistance, which significantly improves the system thermal resistance and reduces heat transfer efficiency. In addition, the lamp beads in the existing LED lamps are directly welded to the On the circuit board, it is difficult to repair and replace the lamp beads, and it is inconvenient to use, and it is difficult to combine in the LED light source module, and it is inconvenient to use
