The high-power wall washer lighting market is relatively active. The high-power wall washer power supply is a very important part of the high-power wall washer. If the choice is not appropriate, the high-power wall washer will not perform its due performance, and even It may not be used for normal lighting. The high-power wall washer uses CREE and Epistar chips as the luminous semiconductor material, placed on the heat dissipation material, and then adds an excellent heat dissipation shell and a stable and professional power supply to protect the internal core wire, which is similar to the shape of a normal fluorescent lamp. Lamp tubes can replace ordinary fluorescent lamps. High-power wall washer is not only super energy-saving and environmentally friendly, but also one of the key products developed by the national green energy-saving LED market project.
Yueyao lighting high-power wall washer is a commonly used lamp for urban lighting, decoration, setting and other functions. It is generally composed of aluminum alloy shell, high-power LED, light distribution lens, waterproof cavity, and waterproof driving power supply. Because LED has the characteristics of energy saving, high luminous efficiency, rich color, long life, etc., the wall washer lamps of other light sources are gradually replaced by high-power wall washer lamps. High-power wall washer has gradually replaced other types of landscape lighting fixtures, and its application will become more and more extensive in the future. High-power wall washer can be used outdoors, indoors, squares, entertainment venues, living rooms, etc. In short, as long as you want It can be used anywhere, except underwater!
At present, a large number of the industry uses a single 0.06W power. If we want to achieve a power of 1W, we need to use 17 same LEDs with a total brightness of 17*6=102lm, which means that it can achieve 100lm/W; If we use a single chip with 1W power, the output brightness is as high as 80lm, and the commonly used one is generally around 60lm. This is a major difference in brightness.
From the perspective of product cost, the cost of high-power LEDs is higher than the cost of low-power. This comes from two aspects. One is the cost of the LED itself, and the other is that high-power LEDs need to be equipped with aluminum heat sinks. The circuit board, coupled with natural heat dissipation, can meet the requirements.
The power module of the high-power wall washer is installed inside the shell, and the space is limited. In order to save space, some manufacturers solder the pin-type components on the PCB. This approach is unacceptable. These surface-welded pin components are likely to fall off due to false welding and other reasons, causing danger. Therefore, socket welding should be adopted as much as possible for these components. If surface welding is unavoidable, it is necessary to provide additional protection for this component by fixing it with glue.
Failure test is a crucial test item in product certification test. This test item is to short-circuit or open some components on the line to simulate the failure that may occur during actual use, so as to evaluate the safety of the product under a single failure condition. In order to meet this safety requirement, when designing the product, it is necessary to consider adding a suitable fuse to the input of the product to prevent over-current from occurring when the output is short-circuited or internal components fail, which may cause a fire hazard.
