When choosing an LED lampshade, generally consider the following three factors:
1. Working environment
LED outdoor lighting fixtures are affected by conditions such as wind, rain and sun, ultraviolet rays in the sun, changes in temperature between day and night, sand and dust in the air, chemical gases and other conditions due to the harsh working environment. . Therefore, the working environment of LED lighting should be considered when choosing LED lampshades.
2. LED lamp material and heat dissipation method selection
The shell and the heat sink are designed as a whole to solve the heating problem of the LED. This method is better. Generally, aluminum or aluminum alloy, copper or copper alloy, and other alloys with good thermal conductivity are used. The heat dissipation includes air convection heat dissipation, strong wind cooling heat dissipation and heat pipe heat dissipation. (Air jet cooling is also a kind of heat dissipation similar to heat pipe, but the structure is more complicated.)
What kind of heat dissipation method to choose has a direct impact on the cost of the lamp. It should be considered comprehensively, and the best solution should be selected with the designed product.
3. LED lampshade selection
In addition, the design and selection of LED lampshades is also very important. At present, transparent plexiglass and pc materials are used. The traditional lampshades are transparent glass products. What kind of material the lampshade chooses is related to the product grade positioning of the design. Generally speaking, The lampshade of outdoor lamps is best made of traditional glass products. It is the best choice for manufacturing long-life, high-end lamps. The lampshade made of transparent plastic, plexiglass and other materials is better for indoor lamps, but it has a limited life when used outdoors. The aging life of the lampshade is shortened due to factors such as outdoor sunlight, ultraviolet rays, sand dust, chemical gases, and changes in temperature between day and night. , Secondly, it is not easy to clean up after pollution, which reduces the transparency of the lampshade and affects the light output.
