First, the working environment
LED outdoor lighting fixtures are subject to harsh working conditions, exposed to wind and rain, sun exposure, ultraviolet radiation in the sun, temperature difference between day and night, dust in the air, chemical gases and other conditions. The lamps are subject to natural ageing treatment year after year. . The impact of these factors should be fully considered in the design.

Second, LED lighting materials and heat dissipation options
The outer casing and the heat sink are designed to be integrated to solve the heat generation problem of the LED. This method is preferable, and aluminum or aluminum alloy, copper or copper alloy, and other alloys with good heat conductivity are generally used. The heat dissipation has air convection heat dissipation, strong wind cooling heat dissipation and heat pipe heat dissipation.

The design of the lampshade is also crucial. Currently, there are transparent plexiglass, PC materials, etc. The traditional lampshade is a transparent glass product. What kind of material is selected is related to the design of the product grade. Generally speaking, the outdoor lamp The lampshade is preferably a traditional glass product, which is the best choice for long-life, high-end lamps. The lampshade made of transparent plastic, plexiglass, etc. is better for the indoor lamp, and the outdoor life is limited. Because of the outdoor sunlight, ultraviolet light, sand dust, chemical gas, temperature difference between day and night, etc., the aging life of the lampshade is shortened. Secondly, the pollution is not easy to clean and clean, so that the transparency of the lampshade reduces the light output.

Third, the LED chip package
At present, LED lamps produced in China are mostly assembled by using 1W LEDs in multiple strings and parallels. This method has higher thermal resistance than advanced packaging technology, and it is not easy to produce high-quality lamps. Or it can be assembled with 30W, 50W or even larger modules to achieve the required power. The packaging materials of these LEDs are encapsulated in epoxy resin and encapsulated in silicone. The difference between the two is that the epoxy resin package has poor temperature resistance and is prone to aging over time. The silicone package is better in temperature resistance and should be selected when using.

Fourth, the design of the radiator
The radiator is a key component of the LED luminaire. Its shape, volume and heat dissipation surface area must be designed to be beneficial. The radiator is too small, the working temperature of the LED lamp is too high, affecting the luminous efficiency and life, and the radiator is too large. Then, the consumption of materials increases the cost and weight of the product, and the competitiveness of the product is reduced.

The above information was compiled and shared by China Led Flood Light Factory , hoping to help those in need.
