Nowadays, LED wall washer light has been put into the lighting project in large quantities. In the next few years, LED wall washer light will develop into an indispensable part of the lighting project. The development direction of LED wall washer light is small and lightweight, and high-power LED light source is the main power.
LED wall washer has been widely used in various places, such as the wall lighting of corporate buildings and government building, historical buildings, entertainment venues, etc.; the scope is getting wider and wider, from the original indoor to the outdoor, from the original local lighting to the current overall lighting, all of which are improvements and development in higher level. The LED wall washer light is controlled by a built-in microchip. In small engineering applications, it can be used without a controller. It can achieve dynamic effects such as gradual change, jumping, color flashing, random flashing, and gradual alternation. It can also be controlled by DMX to achieve effects such as chasing and scanning. Next, EXC will popularize the working principle of the LED wall washer light.
The first thing to understand is the LED chip: the luminous body of the LED is a chip, and the price is very different with preference of Japan and the United States chips. The main part of the LED wall washer light is concentrated on the chip, which is the heart of the LED lamp.
Secondly, the voltage of the LED wall washer is 220V, 110V, 24V, 12V, so we must pay attention to the corresponding voltage when choosing the power supply. In addition to 18V, 36V, these two transformers are relatively few in the market, which are not easy to match, so the 24V or 12V is used for low voltage.
Then what we need to understand is the working temperature of LED wall washer light, because wall washer is usually used more outdoors, so this parameter is more important, and the temperature requirements are relatively high. Generally, it is necessary to withstand low temperatures as well as high temperatures. Otherwise, it is easy to cause problems when replacing lamps in four seasons.
Furthermore, what we need to understand is the protection level of the LED wall washer light. This is an important parameter of the wall washer light and an important indicator that affects the quality of the guardrail tube. We have to make strict requirements. We require a waterproof level of above IP65. Relevant requirements are pressure resistance, chipping resistance, high and low temperature resistance, flame resistance, impact and aging resistance. Grade IP65 6 means: completely prevent dust from entering and 5 means: flush with water without any harm.
Next, we need to understand the control method of LED wall washer light. There are currently two control methods for LED wall washer: internal control and external control. Internal control means that there is no external controller. The designer designs the control system in the wall lamp, and the degree of effect cannot be changed. The external control is an external controller whose effect can be changed by adjusting the buttons of the main control. Usually in large-scale projects, customers can change the effect by themselves, so we all use external control solutions. There are also many wall washer lights that directly support DMX512 control systems.
