Lighting fixtures

Since the LED lamps have been asked for heat dissipation, everyone is concerned about the situation. A luminaire is divided into three major parts: the outer casing, the light source and the power supply. So today, let's solve the heat dissipation of the shell. At present, the technology mainly has the following heat dissipation methods.

Fin radiator:

This is the most common way to dissipate heat. It uses the aerospace aluminum stamping nickel reflow process. The heat sink is thin and light, which achieves the benefits of large convection of the heat dissipation area, but the cost is very high.

Thermally conductive plastic radiator:

Filling the plastic shell with a heat-conducting material during injection molding increases the thermal conductivity of the plastic, which can only be used in the civilian market.

Air Hydrodynamic Radiator:

This is to make a different sun flower line, using the CNC car to work out the air circulation effect.

Fan heat sink:

The aluminum is used as a heat carrier to make a convection effect, and the fan is used as a heat dissipation system, and the quality of the fan is extremely high.

Catheter cooling:

This kind of heat dissipation is mostly used for lamps above 100W. Copper pipes are used to seal the copper particles and adhere to the inner wall of the copper pipe to increase the heat dissipation convection. The copper heat conduction speed is very fast. Therefore, some copper pipes are designed for heat conduction under the light source to conduct heat. On the radiator.

Radiation radiator:

This is simple, apply a radiation heat sink to the heat sink.

Vacuum packaged heat sink:

The heat sink liquid is vacuum-filled into the heat sink core to ensure that the internal heat-dissipating liquid is not volatilized.
