Problems solved by technology

If the temperature of the LED element 20 is not immediately assisted, it will affect the luminous efficiency of the LED grain 22, and even shorten its service life.
In the prior art, the heat energy generated by each LED chip 22 can only be conducted from the bump 221 to the carrier board S through the lead frame 23 in the same way as the electrical connection, and there is no other heat dissipation path. , so it obviously cannot meet the requirement of having LED module 10
[0009] It can be seen that the above-mentioned existing light-emitting diode modules obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

Abstract

The invention is concerned with the light-emitting diode module group, includes the metal circuit board and the complex number of light-emitting diode grain. The metal circuit board includes the metal plate, the first dielectric layer and the circuitry layer orderly; the first dielectric layer is with the complex number of hatch; where the light - emitting diode grain set on and they connects with the circuitry layer by electricity. The invention resolves the problem of thermolysis prolongs the light-emitting diode module group life-cycle and ensures the quality of the production by reinsuring the heat energy generated by the light-emitting diode grain can be transmitted to the metal plate through the base board directly, which can reduce the temperature of the light-emitting diode component.The complex number of hatch can use as the enveloping outskirts of the packaging process and the setting up of the light-emitting is just simple set on the metal basal board, both can reduce the making step of the packaging process and the module forming and their time consuming.

Description

technical field [0001] The invention relates to a light-emitting module, in particular to a method for quickly transferring heat energy generated by light-emitting diode crystal grains, assisting light-emitting diode grains to dissipate heat, prolonging the service life of light-emitting diode modules, ensuring luminous quality, and reducing packaging process and assembly Process steps and time for LED modules. Background technique [0002] A light-emitting diode is a light-emitting element made of semiconductor materials. The element has two electrode terminals. A voltage is applied between the terminals, and a very small voltage is passed through. Through the combination of electron holes, the remaining energy can be excited in the form of light. released. [0003] Different from ordinary incandescent light bulbs, light-emitting diodes are cold-emitting, which have the advantages of low power consumption, long life of components, no need for warm-up time, and fast respons...
