LED wall washing lights, as the name suggests, let the light wash over the wall like water, mainly used for architectural decoration lighting, and used to outline the outline of large buildings. Because LED has the characteristics of energy saving, high light efficiency, rich color, long service life, etc., in 2013, the wall washing lights of other light sources were gradually replaced by LED wall washing lights.
English name LED wall washing lights, also known as linear LED floodlights, because of its long strip shape, also known as LED line lights, its technical parameters and LED floodlights are generally similar to LED circular structure casting lights, LED wall washing lights using Pu micro waterproof valve to solve the lamp internal and external pressure difference and waterproof, and the cooling device rod structure is more suitable for handling a little better.
The LED wall washer power module is installed inside the housing, space is limited, some manufacturers in order to save space, plug components on the PCB surface welding, this practice is unacceptable. These surface-mounted pin type components can fall off due to welding and other reasons, posing a hazard. So these elements take Jack welding as far as possible. If surface welding must be performed, such components, glue fixing, etc. must be used to provide additional protection.
I. Definition:
LED wall washing lights are also known as linear LED floodlights, etc., because of its long shape, also known as LED line lights, mainly used for architectural decorative lighting purposes, as well as for outlining the technical parameters of large buildings and the outline of LED floodlights are generally similar to LED floodlights relative to circular structures. LED wall washing structure of the cooling device is more suitable for handling a little better.
II. Parameters:
Now the application of more LED wall washing lights basically choose 1W high-power LED tube (each LED tube will be made of PMMA, its main function is LED LED tube LED wall washing lamp LED tube share a radiator, some manufacturers each LED tube is placed a small radiator, the light Angle is generally narrow (20 degrees), In (about 50 degrees), wide (about 120 degrees) three, at present, the effective projection distance of high-power LED wall washing lamp (narrow Angle) is 15-20 meters, the common power is about 8W, 12W, 24W, 27W, 36W and other power forms, and the common sizes are generally 300,500,600,1000 and so on. Select different lengths and power densities according to the actual situation.
III. control mode: high-power LED wall washing machine control and internal control of two kinds of control, without the internal control of the external controller can build a variety of change modes (six), external control will be configured external control in order to achieve color change, the current market is also the application of external control.
IV. the main application can achieve:
LED wall washing lights are controlled by built-in microchips. In small engineering applications, dynamic scenarios such as gradient, jump, color flicker, random flicker, gradient alternations can be realized without a controller. It can also be controlled by DMX to achieve chase, scanning, etc.
At present, the main application places are: single-storey buildings, outside the wall lighting historical buildings; The light outside the building through the lighting, the interior local lighting; Green landscape lighting, billboard lighting; Medical, cultural and other facilities lighting; Wine, dance hall and other lighting entertainment places.
