LED lighting design should pay attention to the problem of the radiator

  Radiator is a very critical component for led lighting; its shape, size, thermal contact surface area must be designed to perfect, if the radiator is small, led lamp operating temperature is too high, the impact of the luminous efficiency and lifetime, radiator is too large, consumption of materials will increase the cost and weight of the product competitiveness decline. Led lights are crucial to design appropriate heat sink. Radiator design has the following parts:

 LED lighting design should pay attention to the problem of the radiator

  1. Clear LED lights require cooling power.

  2 design radiator with some parameters: metal heat, thermal conductivity of metal, chip resistance, heat sink thermal resistance, thermal resistance, such as ambient air.

  3 Make sure that the use of the type of scattered, (natural convection heat, strong wind cooling, heat pipe cooling, as well as other thermal cooling mode.) From the cost comparison: natural convection has lowest cost, strong wind cooling medium, heat pipe has higher cooling costs, jet cooling the highest cost.

  4 Make sure the LED lamps maximum permissible operating temperature (ambient temperature plus temperature rise permitted lamps) ,

  5 calculate the volume of the heat sink, the heat dissipation area. And determine the shape of the radiator.

  6 LED lights and the radiator into a complete lighting and power work more than eight hours at room temperature 39 ℃ - Check the lamp 40 ℃ ambient temperature, and see whether meet the cooling requirements to test calculations are correct, if not meet the conditions of use, it will have to recalculate and adjust parameters.

  7 radiator and shade between the seal to do pad waterproof, dustproof, anti-aging lamp and radiator silicone rubber pad or mat, with stainless steel bolts, be sealed waterproof, dustproof.
