Now led wall washing lamp has been widely used in commercial lighting, it can outline the outline of the walls of various buildings, highlighting the beauty of the city at night.
1. Led wall washing lamp bead brightness.
Cymbal.
Galaxy led wall washing lamp used by the lamp bead brightness, its price is not the same.
It is common in the market that the brightness of 1W is 90-130lm, the brightness of 3W is as high as 250LMMagne5W, 320W is the integrated chip, using series-parallel package, it mainly depends on the specific current and voltage.
The common brightness of 1W red light is 30-40lm, the common brightness of green light is 60-80lm, the common brightness of 1W yellow light is 30-50lm, the common brightness of blue light is 20-30lm.
LED lenses are generally made of PMMA, PC, optical glass, silica gel and other materials. The larger the angle, the higher the luminous efficiency.
Using a small-angle LED lens, the light can shine very far.
2. The bead wavelength of led wall washing lamp.
The price of Galaxy led wall washing lamps with the same wavelength and color will be higher, and manufacturers with LED spectrometers are needed to produce solid color products.
Red light: the wavelength range is 600-680, in which the wavelengths of 620 and 630 are commonly used for stage lights, and the wavelengths of 690 are close to infrared.
Blue light: wavelengths range from 430 to 480, where wavelengths of 460 and 465 are commonly used for stage lights.
Green light: the wavelength range is 500-580, in which wavelengths of 525 and 530 are commonly used for stage lights.
