Flashlight reflector
The reflector refers to a reflector that uses a point light bulb as the light source and needs long-distance spotlight illumination. It is a kind of reflective device. In order to utilize the limited light energy, the light reflector is used to control the illumination distance and illumination a...Read more -
Imaging Law and Function of Optical Lens
Lens is an optical product made of transparent material, which will affect the wavefront curvature of light. It is a kind of device that can converge or disperse light. It is widely used in security, car lights, lasers, optical instruments and other fields. The function ...Read more -
Advantages and disadvantages of LED optics
Ultra-thin lens, the thickness is small but the optical efficiency is low, about 70%~80%. TIR lens (total internal reflection lens) has thick thickness and high optical efficiency, up to about 90%. The optical efficiency of Fresnel lens is as high as 90%, which can lea...Read more -
Cob light source
1. Cob is one of the LED lighting fixtures. Cob is the abbreviation of chip on board, which means that the chip is directly bound and packaged on the whole substrate, and N chips are integrated together for packaging. It is mainly used to solve the problems of manufactur...Read more -
How to measure the reflector temperature?
For the use of cob, we need confirm the operating power, heat dissipation conditions and PCB temperature to ensure the normal operation of cob. When using the reflector, we also need to consider the operating power, heat dissipation conditions and reflector temperature ...Read more -
Downlight and spotlight
Downlights and spotlights are two lamps that look similar after installation. Their common installation methods are embedded in the ceiling. If there is no research or special pursuit in lighting design, it is easy to confuse the concepts of the two, and then it is found...Read more -
Optical Applications of Thiessen Polygons
What is a Thiessen polygon? Saxian Sen. Tyson polygon is also called Voronoi diagram (Voronoi diagram), named after Georgy Voronoi, is a special form of space division. Its internal logic is a set of continu...Read more -
Introduction and application of reflector and lens
▲ Reflector 1. Metal reflector: it is generally made of aluminum and needs stamping, polishing, oxidation and other processes. It is easy to form, low cost, high temperature resistance and easy to be recognized by the industry. 2. Plastic reflector: it needs to be demoulded. It has high optical a...Read more -

Installation and cleaning of optical lenses
In the lens installation and cleaning process, any bit of sticky material, even nail marks or oil droplets, will increase the lens absorption rate, reduce the service life. Therefore, the following precautions must be taken: 1. Never install lenses with bare fingers. Glo...Read more -
What’s the difference between optical lenses and Fresnel lenses
Optical lenses are thicker and smaller; Fresnel lenses are thin and large in size. Fresnel lens principle is French physicist Augustine. It was invented by AugustinFresnel, which transformed spherical and aspherical lenses into light and thin planar shape lenses to achie...Read more -
The processing process of optical lens is introduced
Optical cold working 1. Polish the optical lens, the purpose is to erase some rough substances on the surface of the optical lens, so that the optical lens has a preliminary model. 2. After the initial polishing, poli...Read more
