LED lights radiator design

LED lights radiator is a critical component of its shape volume cooling surface area should be designed to be just right, the radiator is too small, LED lights county operating temperature is too high, affecting the LED luminous efficiency and lifetime of the radiator is too large, the consumption of materials to increase product cost and weight of the product less competitive. Design appropriate LED lamps radiator is essential. Design of the radiator has the following components.

LED lights radiator design

1) Confirm the cooling power of LED Lamps. The parameters are: metal thermal conductivity than the hot metal chip thermal heat sink thermal resistance ambient air thermal resistance, etc.

2) Determine the type of heat used (natural convection cooling heat pipe cooling winds and jet refrigeration cooling mode). From the cost is relatively low cost of natural convection, forced air cooling medium high heat pipe cooling, jet refrigeration highest cost.

3) Verify the LED lamps allow the maximum operating temperature (ambient temperature plus temperature rise permitted lamps).

4) Calculate the volume of the heat sink area, and determine the shape of the radiator.

5) The radiator with LED lights combined into a complete lighting and powered T for more than 8h at room temperature 39 ℃ ~ 40 ℃ environment temperature checks to see if the lamps meet the cooling requirements to test calculations are correct, does not satisfy the conditions of use as will have to recalculate and adjust parameters

6) The radiator to do with the lampshade waterproof and dustproof seal between the radiator lampshade to pad aging of the rubber pads or silicone rubber pad with stainless steel bolts do sealed waterproof and dustproof.
