What are the light distribution lenses and control methods of the wall washer lens?

LED wall washers, also known as linear LED flood lights, are mainly used for architectural decorative lighting or to outline the outline of large buildings. Its technical parameters are generally similar to LED floodlights, and are mainly used for architectural decorative lighting. What I want to introduce to you today is about the lamp lens and control methods of the wall washer lens. Content.

Wall washer with light lens:

Angle points:

Different angles have different lighting heights. The smaller the angle, the higher the height. If the angle is too small, a light beam will be formed, and there will be dark areas between the beams. On the contrary, the larger the angle is, the more uniform the light is mixed, but the lighting height is not high, so the angle should be adjusted according to the lighting. Light height is required.

Type of head lens:

• Glossy surface: high light transmittance, the disadvantage is that the light mixing is not ideal and easy to cause flare, especially the lens with poor material. Generally used for large-degree lenses (above 30 degrees) or lamps that require high lighting.
• Bead surface: It has the effect of refraction, so the light mixing is relatively good, but part of the light is refracted back, resulting in a decrease in light transmittance, and the lighting height will also be affected a little. It is generally used for lamps with high lighting uniformity requirements. It is recommended to use lamps above 24w/m.
• Frosted surface: Frosted has an emulsification effect, the light mixing effect is quite good, the single light transmittance is relatively reduced, and the frosted lens is not commonly used.
• Flat stripes: shaped like waves, aka striped bi-angle lenses
• Trapezoid stripes: polarized lenses, which are shaped like a ladder with one layer higher than one layer, with different directions.

The control method of the wall washer:

Both internal and external control. Internal control means that there is no need for an external controller. The designer designs the control system in the Xian wall lamp, and the degree of effect cannot be changed. External control is an external controller, and its effect can be changed by adjusting the buttons of the main control.

• Monochromatic always bright: that is, it is bright when power is on, and the color is fixed
• Internal control colorful: automatically change the fixed effect after power-on, there are three kinds of internal control gradient, internal control jump, and internal control changeable
• DMX512 external control: The lamp is controlled by the controller to transform the program effect required by the customer (the effect can be changed).
