The above parameters must be considered when we choose the LED high-power wall washer. In order to distribute the light emitted by the LED tube for the second time to reduce the light loss and make the illuminance better, each LED tube of the wall washer will have a High-efficiency lens made of PMMA. The connection of the wall washer is easier to understand by controlling the connection diagram.

In practical applications, it will also appear that the constant current drive is not very good, and there are many damages, so how to make the wall washer work better.

LED constant current device, related to LED high-power products, we will all mention constant current drive, so what is LED constant current drive?

Regardless of the change in the size of the load, the circuit that keeps the current of the LED constant is called the LED constant current drive. If a 1W LED is used in the wall washer, we usually use 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. I try my best to choose a constant current source with high efficiency, which can reduce energy loss and temperature.

The voltage of LED wall washer is 220V, 110V, 24V, 12V, so we must pay attention to the corresponding voltage when choosing the power supply. In addition, there are 18V and 36V. Because these two transformers are relatively few in the market, it is not easy to match the transformer, so the low voltage generally uses 24V or 12V.

Operating temperature:

Because the wall washer is usually used more outdoors, this parameter is more important, and the temperature requirements are also relatively high.

Protection level:

This is an important parameter of the wall washer, and it is also an important indicator that affects the quality of the guardrail tube. We have to make strict requirements. When we use it outdoors, it is best to require the waterproof level to be above IP65. It is also required to have relevant pressure resistance, fragmentation resistance, high and low temperature resistance, flame resistance, and impact resistance aging grades

IP65 6 stands for:

Completely prevent dust from entering. 5 means: Rinse with water without any harm.

control method:

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, and its effect can be changed by adjusting the buttons of the main control. Usually in large-scale projects, customers can change the effect by themselves. We all use external control solutions. There are also many wall washers that directly support DMX512 control systems.

Mirror:

The glass reflective lens has a light transmittance of 98-98%, is not easy to atomize, and can resist UV radiation.

light source:

Generally, 1W and 3W LEDs are used as the light source. However, due to the immature technology, it is more common to use 1W in the market in 2013. Because 3W generates a large amount of heat, the light decays faster if it is not done well.

Standard sizes:

The default unit length is 1 meter. Since the shell is a high-temperature aluminum profile drawn from the model, the length can be customized according to customer requirements. The width and height cannot be changed unless the mold is re-opened, but the cost of mold-opening is expensive. Generally, manufacturers and customers do not Will be used, except in special circumstances.
