Wall washing lamps are generally assembled from several different materials
From this tedious process, it can be found that no matter how good the thermal conductivity material is, it will be defeated by the thermal resistance impedance. The thermal impedance will be formed by the air, the unfixed pores at the joint, the heat dissipation gasket, the powder formed after the evaporation of the heat dissipation paste and the film thickness of the multilayer heat conduction adhesive film. These multi-level thermal resistances will hinder the heat conduction rate. The heat conduction is very slow, even less than the surface layer of LED lamps, and the heat degree increases continuously. The white backlight ink on the surface of aluminum substrate should not only reflect, but also diffuse the heat of the lower layer through the backlight ink on the surface.
LED lamps are generally assembled by several different materials, such as the heat dissipation part of the lamp cup is metal, and the lampshade is plastic; the lamps will generate certain heat in the work, and the coefficient of thermal expansion of different materials is different, after long-term use, gaps will be generated at the joints of different materials to enter the air; when used in the environment with high humidity, the temperature inside and outside the lampshade is different, and the inner part of the lampshade is The heated gas will be cooled at the lampshade. If the gas contains more water vapor, water mist and water drop will be generated. After lighting for a period of time, this phenomenon will disappear. Therefore, the humid environment is also a factor affecting the life of LED lamps.
It is more difficult to heat and waterproof the LED wall washing lamp, which needs drainage and convection design. In the production process of the LED wall washing lamp, the first step is to use the wall washing lamp glue filling machine for glue filling, and then the glass cover plate is glued with glass glue to achieve structural waterproof.
There will be no glare or over bright interference in the luminaire itself: all the lighting design is mainly to interpret the design elements of the illuminated object through the light, rather than to appreciate the glare of the luminaire itself, otherwise, the residual light of the eyes is easily interfered by the reflection of the over bright light source, instead, it is not comfortable to appreciate the situation to be interpreted by the lighting equipment.
