How to choose the luminous angle of LED wall washer in outdoor lighting?

LED wall washers are widely used to decorate and beautify the outline of buildings, as well as for entertainment places and square lighting rendering effects, which are beautiful, practical and safe. But how to choose the light angle of LED wall washer? The LED wall washer lights have different luminous angles, so the price is also different. The price of luminous characters with special requirements is relatively expensive.

LED wall washers generally have narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees) light-emitting angles, generally determined by the lens, with a floodlight effect, and the bracket is generally adjustable. The light angle affects the light concentration, thus affecting the light projection distance. The specific lighting angle selection is related to the lighting color, power, required projection height, installation distance, etc. It is necessary to consult a professional LED wall washer manufacturer to avoid design errors.

The light emitting angle of LED wall washer lamp beads is generally 80~140 degrees, so it is necessary to use a lens for light distribution. Generally, a conical lens is used to gather light. Commonly used lens angles are 15°, 30°, 45°, 60° and 90°. The conical lens is fixed by a bracket in the application, and many manufacturers make the cover panel and the lens as a whole.

In addition, for power-type led wall washers, the angle of light is generally determined by the bracket, lens or mold. The depth of the bracket cup determines the angle, and the lens and mold have various angles for you to choose, such as 120°, 140° or 160°.

Analyze the cause of the fire on the LED wall washer:

In the lighting industry, I heard that there are cases of fire after installing LED wall washers. Indeed, this situation is rare, and it is also an individual case. As for the LED wall washer catching fire after being installed, LEDER lighting engineers analyzed this phenomenon in this way:

(1) Low-voltage wall washer: If the low-voltage wall washer catches fire after it is installed, it may be caused by a short circuit and burnt due to the reverse connection of the wires.

(2) High-pressure wall washer: If it is a high-pressure wall washer, the first consideration is the burnout caused by the driver being broken.

(3) Each power supply can only work within the rated power range. If there are too many wall washer strips, the negative pressure will be too heavy, and the negative pressure may also cause the lamp current to be unstable, resulting in damage and burning.
