To solve the heat dissipation of LED lamp beads, the heat dissipation of LED lamp bead chips and the heat dissipation of LED lamps are mainly from two aspects. The heat dissipation of the LED lamp bead chip is mainly related to the selection and process of the substrate and circuit. The heat generated by the LED lamp bead chip constitutes the ambient temperature and is dissipated into the air through the shell of the lamp. The heat dissipation of the LED lamp bead is not good, because the heat capacity of the LED lamp bead chip is very small, and the accumulation of a little heat will quickly increase the junction temperature of the LED lamp bead chip. If it works at a high temperature for a long time, the life of the LED lamp bead. The number will be shortened very quickly. There are many ways for the heat of the LED chip to be able to actually guide it to the outside air. The heat generated by the LED lamp bead chip comes out of its metal heat sink, first passes through the solder to the PCB of the aluminum substrate, and then passes through the thermal conductive adhesive to the aluminum heat sink. Therefore, the heat dissipation of LED lamp beads actually includes two parts: heat conduction and heat dissipation.

The heat dissipation of the lamp housing of the LED lamp bead will also have different choices according to the power size and the place of use. There are mainly the following cooling methods:

1. Aluminum heat dissipation fins: This is the most common heat dissipation method for LED lamps and lanterns. Aluminum heat dissipation fins are used as part of the shell to increase the heat dissipation area.

2. Thermally conductive plastic shell: Fill the thermal conductive material during injection molding of the plastic shell to increase the thermal conductivity and heat dissipation capacity of the plastic shell.

3. Air hydrodynamics uses the shape of the lamp housing to create convective air, which is the lowest cost way to enhance heat dissipation.

Fourth, the heat pipe uses the heat pipe technology to conduct the heat from the LED lamp bead chip to the heat dissipation fins of the shell.

At present, the luminous power of the LED lamp bead is still relatively low, which then causes the junction temperature of the LED lamp bead to rise, and the life of the LED lamp bead decreases. In order to reduce the junction temperature and increase the lifespan, it is necessary to attach great importance to the heat dissipation of the LED lamp beads.
