How about the use effect of wall washing lamp?
Now we find that led wall washing lamps have begun to appear widely in our days and become indispensable lighting supplies in many places. So what about the application of LED wall washing lamp? Led wall washing lamp has won the praise and trust of our customers for its bright and novel colors, diversified styles and thoughtful service. The product can not only provide comfortable lighting space, but also meet people's physiological and health needs. It is a healthy light source to protect vision and environmental protection. Very cost-effective.
In the production process of LED wall washing lamp, we may encounter such a problem. After the LED chip is installed in the finished product, one of them does not light up, but it can light up again after it is removed. Moreover, I believe this problem is often encountered by professionals. Generally, it will be like this:
This depends on the series parallel connection. If a single one in the series is not bright, it may be a short circuit of solder paste or chip leakage; However, if it is determined that it is a single dead lamp, but it turns on again when it is removed, it will be caused by solder paste soldering for a while; Second, there are problems with the product itself. When the solder paste is solidified, the stress will cause the gold wire of the product to open at a breakpoint, but after it is removed, the stress is released, and the gold wire at the breakpoint is combined again, so it lights up again, but the gold wire has been disconnected at this time.
There are two kinds of LED waterproof wall washing lamps:
1. The potting adhesive belonging to ab components is used for large-area waterproof. Direct contact with electronic components can be used on one or more sides, or potted. This completes the use of glue, and after the adhesive is completely cured, the appearance becomes flat and beautiful. Even if you put it in water, it won't be a problem. This is a high-end waterproof（ It is mainly used for display screen, wall washing lamp, underwater lamp, lamp strip, etc.).
2. The other is the bonding of LED waterproof wall washing lamp, which belongs to a single component and is used for bonding and sealing in a small area. After curing, the silicone is lubricated smoothly without uneven feeling（ Mainly used for bulb lamp, spotlight, street lamp, etc.).
Led wall washing lamp can be divided into monochrome constant light, colorful internal control and full-color external control according to its function. It can be divided into red light, green light, blue light, yellow light, white light, warm white and customized light color of specific wave band or color temperature according to light color. Led wall washing lamp can be used on billboards. The key is to see the requirements of customers. General outdoor billboards use projection lamps. The lighting function of wall washing lamps and projection lamps are two kinds: one is the overall function; One is one-sided action.
