Lighting optical concepts and classification

1, the basic concept of optical illumination optical belong to of nonimaging optics, design through the direction and intensity distribution of light energy, convert light illuminated area or the form of brightness, ultimately meet the demand of lighting vision.

2, lighting lighting optical optical classification consists of optical transmission and reflection optical transmission optical medium mainly in a transparent medium, by way of refraction and reflection of mixed light, control the purpose of the light; Panel control belong to the transmission of optical light. Reflective optical main mirror or diffuse surface as the medium, form to reflect the light, and control light.

the transmission of optical optical analysis lighting, mostly in the form of a lens by refraction and reflection of light distribution. Using the law of conservation of energy, intensity distribution is redistributed, changing the direction and the size of the light to realize all kinds of lighting system. Based on luminance target design, it is relatively complex, a lot of free surface medium is not only to change the light intensity, but also light intensity to the area of material, namely the degree of reflection, consider the direction of the human visual observation, comprehensive factors, the terminal to feedback to get the final size and the direction of the light intensity distribution.

3, 1) the comparison of optical transmission and reflection optical Light efficiency perfect circumstances, the reflection optical can higher than transmission optical 2) Control ability for a small light source such as LED light, transmission ratio reflects light control ability. 3) Material required transmission control light to medium high purity, easy dispersion or color distortion phenomenon; Weather resistance is poorer; Reflection light, mirror is easy to appear the aperture phenomenon, such as irregular or covered is relatively difficult to design and manufacture high-end reflective surface, the effect will be better than the mirror. 4) The other transmission control of the lens on the LED light itself has a protective effect; Because both transmission, refraction and reflection, lens smaller; Reflection of light reflector is open, need additional measures to protect the LED.
