LED wall washing lights are divided into LED high-power wall washing lights and LED low-power wall washing lights according to the size of the lamp bead power. Generally, a single LED wall washing lamp of 1W and above 1W lamp beads belongs to LED high-power wall washing lamp! LED wall washing lamp is a kind of LED outdoor lighting, our company mainly produces LED digital tube, LED wall washing lamp, high-power LED wall washing lamp. The company with many years of LED manufacturing experience, and has a strong drive circuit design capabilities, unique appearance structure design capabilities, the ability to continuously improve quality and rapid response to market demand, has grown into a mainstream supplier of LED lighting products market.
Below, what are the main parameters of LED wall washing? What to pay attention to when using! Due to the large volume of the LED wall washing lamp, the heat dissipation is better, so the difficulty in design is greatly reduced, but in practical applications, there will be constant current drive is not very good, and there are a lot of damage, so how to make the wall washing lamp better operation, control and drive is the key.
LED high-power wall washing lamp mainly attaches importance to the following parameters:
First, the power size: the power size of the wall washing lamp determines the distance it projects, and generally there are 18W,24W,36W,48W and other parameters. In addition, because of the problem of heat dissipation, the use of a single 1W wall wash lamp for 1 meter should not exceed 36W! Otherwise the heat dissipation is not good, there will be a serious situation of light decay!
Second, color: divided into seven colors, full color, monochrome
Color temperature: about 2200K (amber) 3000K (warm white) 4000K (incandescent lamp) 6000K (positive white) 7000K (cold white)
Fourth, the projection distance: the projection distance is closely related to the power size and the lens luminous Angle! The luminous Angle that many people pay attention to is actually taking into account the projection distance. Generally, the effective projection distance of the wall washing lamp is 3-10 meters
Five, the luminous Angle: divided into narrow (about 20 degrees), medium (about 50 degrees), wide (about 120 degrees)! The narrower the Angle of light, the longer the projection distance
Voltage: According to the characteristics of LED, the power supply is constant current, low voltage, DC. That is to say, LED lamps need to be connected to the mains power supply! The power supply has three kinds of internal, external and centralized power supply. According to the different lamps produced by each manufacturer, the power supply is also different!
Seven, control mode: according to the different scenarios to be realized, the control mode is not the same! If it's monochrome, you don't need a controller. The general controller is divided into 485 controllers (to achieve change scenes are generally: gradient, jump, etc.) DMX512 (to achieve change scenes are generally: chase, water, animation, text, etc.)
The same type of wall washing lamp, the height and width can not be changed (to re-open the mold), but the length can be changed at will! Related to LED high-power products, we will mention the constant current drive, what is the LED constant current drive? Regardless of the size of the load. The circuit in which the current of the LED remains unchanged is called the LED constant current drive. If the wall washer lamp is used with 1W LED, we usually use 350MA LED constant current drive, and the purpose of using LED constant current drive is to improve the service life of LED and light decay. The choice of constant current source is based on its efficiency and stability, I try to choose a constant current source with high efficiency, which can reduce energy loss and temperature.
