LM-82 is a standard for the reliability testing of LED test instruments released by the American Lighting Engineering Society (IES). This standard specifies a series of test methods to help evaluate the performance and reliability of LED lighting products. LM-82 standard LM-82 Standard Overview The LM-82 is a standard for testing the reliability of LED lighting products. It aims to provide a stand...
Lighting is an indispensable part of human life. It can not only provide light, but also has an important role in shaping the environment, improving work efficiency, and promoting human health. In order to ensure that the quality and performance of lighting products meet international standards, Lighting Research Center has formulated a series of lighting standards, including the LM-82 standard. T...
LED light engines and integrated LED bulbs are often applied to various types of lamps, including decorative lamps, non -fixed direction lights, etc. Generally speaking, the performance of LED bulbs, including light flux, light efficiency, color, life, etc., will be affected by the LED knot temperature, and the knot temperature is also affected by the installation method and application of LED bul...
If your application requires measurement of a widely diverging beam, an integrating sphere is the best option to consider. An integrating sphere is an optical component that captures a light beam and enables you to measure the power in the beam under conditions that would otherwise be very challenging. A widely diverging beam that might overfill a regular sensor aperture. Sphere integration LPCE-2...
Foreword: With the rapid development of the LED industry, the application range of LED lamps is becoming wider and wider, and there are more and more types of lamps. Flat light is one of them. Flat light is suitable for indoor lighting such as living room, bedroom, corridor, kitchen, viewing balcony, etc. At the same wattage as traditional lighting sources, flat panel lights are energy efficient, ...
The functions of the optical integrating sphere tester include light receiving, uniformly illuminated object surface, spherical parallel light tube, etc. Its principle is that after light is incident from the input hole, the light is uniformly reflected and diffused inside the sphere. Below take Lisun’s optical integrating sphere system as an example to introduce it in detail. The role of op...
The integrating sphere is a cavity sphere coated with a white diffuse reflection material on the inner wall, also known as a photometric sphere, a luminous sphere, etc. One or several window holes are opened on the spherical wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface,...
Generally speaking, the optical diffuser, when used carefully, can reduce the small errors caused by the uneven distribution of the incident light source on the detector or the deviation of the beam during measurement, so the accuracy of the integrating sphere measurements can be improved. However, in precise measurement, an integrating sphere must be used as an optical diffuser to minimize the ab...
1. Operation steps: 1. First connect the probe and optical fiber to the corresponding position of the integrating sphere, and fix it. 2. Turn on the DC power supply of the integrating sphere system configuration. 3. Turn on the computer, then open the computer desktop test software, and select “System Settings” on the software, and connect the DC power supply, the electric parameter me...
