LED wall washer is relatively large in size and better in terms of heat dissipation. Because LED wall washer generally has a higher power than LED linear lights, it has a bright chemical effect outdoors and is used in scenes with a long range. The housing has a large volume and space, so In terms of design, the difficulty is greatly reduced. However, in practical applications, constant current drivers are not very good, and there are many damages. Therefore, how to make the wall washer work better, the focus is on In terms of control and driving, what is an LED constant current device?
High-power products related to LEDs will all mention constant current drive, so what is LED constant current drive? Regardless of the size of the load. The circuit in which the current of the LED remains unchanged is called LED constant current drive. If a 1W LED is used in the wall washer, it is usually a 350MA LED constant current drive. The purpose of using the LED constant current drive is to improve the life and light attenuation of the LED. The choice of constant current source is based on its efficiency and stability, as far as possible to choose a high-efficiency constant current source, which can reduce energy loss and temperature. LED lights with the same parameters (same power and color temperature), but the prices of different brands and factories are very different. This is so-called "you get what you pay for". The quality of the product is good or bad. The driving power supply accounts for an important factor. Because electronic components of different brands are used, the product cost and durability are also different. Therefore, when buying, don't just use price to compare, but use cost-effectiveness to compare.
