The 'light distribution curve' of LED downlights and other lighting fixtures is so important! ||

The final effect of the lighting space is inextricably related to the lighting (especially LED downlights). The display of light is undoubtedly the power of LED lighting fixtures. In the arrangement and selection of lighting fixtures such as LED downlights and LED spotlights, The simulation and implementation of professionals are needed to make the lighting space more versatile. Lighting design will inevitably deal with the 'light distribution curve'. So how much do you know about the light distribution curve? What role does it play in lighting effects and lighting design? Before explaining this concept, we must first understand what 'light intensity' is? The luminous flux (the luminous ability of the light source or the luminaire, the unit is lumens) emitted within a unit solid angle in a certain direction in a space is the light intensity, and the unit is candela. So how big is the solid angle of the unit? Suppose there is a sphere with a radius of R. According to the definition, the unit solid angle is the solid angle formed by the boundary of a surface with an area of u200bu200bR on the sphere and the center of the sphere. The surface area of u200bu200bthe entire sphere is πR, so the entire space has a total of π (approximately) unit solid angles. Turn on the light source or LED lamps, and connect the vertices of the light intensity vector arrows in all directions in the entire space to form a three-dimensional light intensity envelope. The light distribution curve is actually the boundary line of the profile through the center of the light-emitting center of the envelope. If you want to know the actual light intensity value of the optional light source lamp in a certain direction, just divide the light intensity value at that angle on the light distribution curve by the K value. The generation of light source incandescent lamps that have been eliminated have a variety of different powers for users to choose, such as w, w, w, w, w and so on. For the convenience of production and interchange, they are usually designed into a unified lamp holder, the most common is screw E. Although the luminous flux corresponding to each power source is different, their light-emitting point positions are almost the same. The LED downlights, LED spotlights and other lighting fixtures designed by the luminaire manufacturers can usually be equipped with various light sources of different powers, and can only draw a light distribution curve and apply to all optional light sources! While satisfying the light, reasonable lighting (especially LED downlights) is also the key point to be mastered. When choosing LED downlights, LED spotlights and other lamps in lighting design, a solid grasp of the knowledge of light distribution curve can make the lighting effect. It is more professional and enjoyable! Introduction Optoelectronics focuses on lighting design, production and construction, providing overall solutions for LED lighting projects such as airports, hotels, commerce, and offices, and is the designated lighting supplier for major domestic airports. ---Contact address: Lighting selection website on the floor of Changhong Science and Technology Building, Science and Technology Park, Nanshan District, Shenzhen
