1. In order to make the illumination of the LED lamp uniform, the LED lamp should be designed with secondary light distribution. The general practice is to add a lens on each high-power chip to make the light more concentrated to the intended location. The best method is to design Rotating the light distribution lens at any angle can make the illumination uniform illumination of the luminaire to a satisfactory result.

2. Arrange more chips on the outer circumference of the lamp, because the illumination of a certain point is proportional to the luminous intensity of the light source, and inversely proportional to the square of the distance. The closer the LED lamp is to the edge of the lamp, the farther it is, the light required. The greater the power. Different arrangements of light distribution are used on the luminaire.

3. Street lamps, landscape lighting fixtures, can be designed into butterflies, bats, ovals, rectangles, etc., in order to maximize the coverage and uniformity of brightness, that is, to meet the overall brightness uniformity, to avoid the emergence of zebra effect.

4. LED lights must pay attention to the treatment of glare. Because the LED light is a point light source, a light is composed of many light-emitting points, and the light emitted by the light has a single wavelength. Similar to the laser, the loss of light in the air is smaller than that of the ordinary light, which is irritating to the human eye and makes people feel Uncomfortable, this is a problem that must be solved. Reducing the luminous intensity can effectively reduce the glare, but it will reduce the illumination; using a frosted lampshade or a translucent cover can also soften the light output from the LED lamp, but at the cost of reducing the illumination, the two are contradictory, the key is It is reasonable to choose between the two, which has the least impact on glare and less illumination.
