Analysis of Jiangmen led wall washing lamp manufacturer
The fault analysis of high-power wall washing lamp is the process of analyzing the unsuccessful high-power wall washing lamp. In order to understand the cause of the equipment failure, it is necessary to study each component of the high-power wall lamp outdoor wall lamp. First of all, we should analyze the failure time of high-power wall lamp. For components close to the design life, retirement will not be analyzed. Other components will consider whether to perform photoelectric parameter test, and then perform appearance test in case of open circuit fault. In case of open circuit failure, optical microscope, metallographic microscope, etc. will be used for visual inspection to analyze possible disadvantages. If there is a problem with pins and bonds, the electron probe microscope will be used to analyze the cause of the problem. Infrared tests are performed on the components to detect internal defects. After that, fixed-point analysis test was carried out to determine the cause of the failure.
In the production of high-power wall washing lamp, in order to improve the luminous effect of the product, the selection of optical lens is very important, so we know what raw materials are used for the optical lens of high-power wall washing lamp on the market? It doesn't matter if I don't know! Let's talk about the optical lens.
We know that the optical lens of high-power wall washing lamp is generally divided into "primary lens" and "secondary lens". The "lens" commonly used by outdoor lighting factory mostly refers to the "secondary lens" connected with the light source. And the meaning of primary lens actually refers to the light source itself. Now let's talk about it side by side: "secondary lens" for short: "lens".
Common lens materials are as follows:
(1) Silica gel lens: small size silica gel lens has high heat resistance and can be reflow welded, so it is commonly used in high-power wall lamp packaging industry.
(2) PMMA lens: PMMA lens is the common lens of high-power wall washing lamp we call today, also known as "acrylic optical lens" by occupation. Its main feature is that its light transmittance can reach more than 90%, its temperature resistance is slightly weaker than that of silica gel lens, and its working temperature cannot exceed 80 ℃.
