As we all know, the commodity itself has no vitality. Companies with only commodities, no famous brands, or only OEM production and no famous brands also have no vitality and sustainability. With the improvement of people's quality of life, the initiative of customers is becoming stronger and stronger to a certain extent. Many customers think that a famous brand is trustworthy and reliable, and the consumption of famous brands is becoming more and more significant. This requires that the well-known brands of wall washing lamp manufacturers be well-known.
Led wall washing lamp lens; there are many types of myopia, ranging from 5 degrees to 120 degrees. The smaller the degree of myopia, the narrower the wall of the direct light source, and the higher the aspect ratio of the direct light effect. The basic wall washing lamp in the general sales market is generally used between 30 degrees and 60 degrees, and there is also a unique narrow light with low output power glasses. At present, there are many kinds of asymmetric encryption angle lenses in the market, such as 10 ° * 60 ° and 20 ° * 45 ° and so on.
The structural waterproof function of the wall washing lamp manufacturer's products: the unique structure is beneficial to the discharge of water from the shell, and the new waterproof silicone rubber can ensure the tightness of the lighting lamps and ensure no water seepage and dust. Using LED as light source, the consumption is small. Therefore, even if many led wall washing lamps are used, it will not cause great pressure on energy consumption. And the LED light source projects far away than the general light source, and the picture quality is high. Therefore, with the characteristics of environmental protection, energy saving and high efficiency, the high-power LED wall washing lamp has completely replaced other wall washing lamps.
In order to make the rated value of the LED wall washing lamp at the operating scale ac85-269v with a wide operating scale, the LED series connection and parallel connection of the LED strip are very important. Because today's switching power supply is generally non isolated blood pressure lowering switching power supply, when begging for a wide working voltage, the output voltage does not have to exceed 72V, and the operating scale can reach 85-269v by typing in the working voltage. In other words, the number of strings is not more than 23. It is not necessary to have too many series connection numbers, otherwise the rated voltage is very high and the scalding is not optimistic. 6 / 8 / 12 series connection is recommended. The total electric flow should not exceed 240mAH. There is also a wide working voltage scheme, that is, first use L6561 / 7527 to raise the working voltage to 400V, and then lower the blood pressure, which is equivalent to two power transformers, and the cost is twice as high. This scheme is not cost-effective and has no sales market.
