LED wall washers are more widely used in outdoor urban lighting, but many customers do not know how to choose the right lamps when purchasing wall washers. Buying LED wall washer can start with three skills, let's follow Guangchen Xiaobian to learn about it.

First, the waterproof level of led wall washer

Led wall washers are basically used outdoors, so there are requirements for waterproof grades when purchasing. This is also a key element in the selection of LED wall washers. Be sure to consult clearly when choosing, generally the waterproof level must be at least IP65 or above. Lamp manufacturers are required to ensure that the lamps can withstand long-term use under harsh conditions of outdoor wind, sun, and rain.

Two, led wall washer control method

There are three conventional control methods for led wall washer, monochrome constant light, internal control and external control. The internal control, like the monochrome, does not need to be connected to the controller, it can be directly powered on. Internal control procedures cannot be changed. External control requires a controller, and the effect can be programmed according to customer requirements. Its pattern animation is more. Many large-scale projects use DMX512 external control wall washer to do. The synchronization effect of multiple buildings can be achieved.

3. LED wall washer light source chip

The light sources of led wall washers are generally divided into two types: high-power imitation lumen lamp beads, single 1-3W ones, and there are generally three types of chips, namely Taiwan Jingyuan, Guanghong chip, and Purui chip. This imitation lumen lamp bead is a lamp bead that has been used more in the past. The other is the Osram 3030 SMD lamp bead, which is basically used now. This chip is foreign and has good stability. He mainly follows the lamp. The board welding is machine-mounted, unlike the artificial lumen, which is manually welded. The bottom of the 3030 chip lamp bead has more contact with the pad, and the heat dissipation is better, and false welding is basically not generated. Another point is that the patch now relies on machines, which are faster than manual labor. Quality stability has been improved. Production has also accelerated. 3030 Osram Wall Washer's regular specifications are 12W, 15W, 24W, 36W, 48W, 72W. Variety styles are more. Now many large-scale government projects require chips to be brands such as Osram!
