With the change of social and economic development trends and the gradual increase of people’s environmental awareness, energy conservation and emission reduction have become part of the theme of our lives, and the reason why outdoor Led lamps can be widely used by people is because LED outdoor lamps have the characteristics of environmental protection and energy saving. LED lighting products not only can effectively save energy, but also has the effect of beautifying the environment to a certain extent.
Precautions for led outdoor lights:
1. Working environment
Due to the harsh working environment of led outdoor lighting, it is affected by wind, rain and sun, ultraviolet rays in the sun, changes in temperature between day and night, sand and dust in the air, chemical gases, etc., and the lamps are subject to natural aging treatment year after year . The influence of these factors should be fully considered when designing.
2. The choice of led lamp material and heat dissipation method
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. Jet cooling heat dissipation is also a kind of heat dissipation similar to heat pipe heat dissipation, but the structure is more complicated.
Due to the complex working environment of outdoor led lights, it is affected by natural conditions such as temperature, ultraviolet rays, humidity, rain, sand, and chemical gases in rainy days. Over time, it will cause serious problems of led light attenuation. Therefore, in the final consideration, outdoor lighting designers should consider the impact of these external environmental factors on outdoor LED lighting when designing.
The design and selection of the lampshade is also very important. At present, transparent plexiglass and PC materials are used. The traditional lampshade is a transparent glass product. What kind of material is selected for the lampshade is related to the product grade and positioning of the design. Generally speaking, the lampshade of the outdoor lamps LED can be traditional glass products, it is the 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 and 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.
