How to predict the life of LED? In general description, LED can be used for more than 50000 hours. Even some manufacturers promote their LED can operate 100000 hours or so. The main problem in this aspect is that the LED is not simply not working, and its rated service life can not be calculated by the measurement of the traditional lamp. In fact, when we test LED service life, nobody would be staying at the side of the lamp waiting it stop working. However, there are still other ways to measure the service life of LED. The reason why LED can work longer is because it won’t cause the problem of filament fuse. LED does not work directly, but it will gradually degenerate as time goes by. There are predictions show that the high quality LED can maintain the original lamp brightness of more than 60% after 50000 hours of continuous operation. Assuming that LED has reached its rated service life, actually it may still shine, just the light is very weak. If we do not consider the power a...

Five kinds of LED Efficiency Compare LED efficiency and life, the conception of efficiency is more complex. Firstly, there are three kinds of general efficiency。 Firstly, for lamp beads, there are two concepts of efficiency: Lamp beads luminous efficiency, how much light can be issued every 1W input power. This efficiency is the indicator to measure the light efficiency of lamp beads, not the indicator to measure the light efficiency of total luminaries. Therefore, the light efficiency of single LED is the basic for the light efficiency of total luminaries; it is not equal to the light efficiency of the total luminaries. Lamp beads conversion efficiency means that every 1W input power, how much power is used to emit light. Luminous efficiency is generally used. Conversion efficiency is often used to assess the development level of the chip. Secondly, the efficiency of lamp beads in the application environment generally does not use. However, it is generally used to assess the ...

Recently, LISUN engineers outside India, to do the installation training of LPCE-3 compact spectrum radiometer integrating sphere system for customers. The customer ordered the LPCE-3 compact spectrum radiometer integrating sphere system from LISUN this time. LPCE-3 is a CCD Spectroradiometer Integrating Sphere Compact System for LED Testing.

How to predict the life of LED? In general, LED can be used for more than 50000 hours, and some manufacturers are promoting their LED to operate for about 100000 hours. The main problem in this area is that LED is not simply no longer operational. Its rated service life can not be calculated by traditional lamps and lanterns. In fact, when testing the life of LED, no one will be waiting for it to stop functioning. However, there are other ways to measure the life of LED. The reason why LED is durable is that it does not produce filament fuses. LED will not stop operation directly, but it will gradually deteriorate over time. It is predicted that high quality LED can maintain more than 60% of the initial lamp brightness after 50000 hours of continuous operation. Assuming that LED has reached its rated service life, it may still be luminous, but the light is very weak. Without considering the power and driving failures, the life span of LED is characterized by its decay, that is, the lon...

Installation and training of LPCE-3 CCD Spectroradiometer Integrating Sphere Compact System （India） A company in India recently purchased a set of LPCE-3 CCD Spectroradiometer Integrating Sphere Compact System . Shanghai Li Shan engineer went to customer company to carry out equipment installation training. [caption id="attachment_10361" align="alignnone" width="800"] a-photo-of-with-our-engineer-and-customer-after-the-training[/caption] The integrating sphere spectrometer testing system is the most basic luminaire testing equipment, and is first considered by the manufacturers and laboratories of lamps and lanterns. This set of equipment is also one of our hot selling products. We will connect the internal connections in front of the factory. After the customers receive the equipment, they only need to connect the power supply and electrical parameter meter to the inside of the cabinet according to the instructions. Our equipment and services have been r...

Two Directions on LED Intelligentized: Intelligent Agriculture and Lifi With 4.0 concepts emerged on the industry, the traditional mind of manufacturing is experiencing unprecedented impact, integration and upgrade of industrialization and information will be the main theme of the transformation for production structure in the future. LED industry as a huge lighting market, in the new historical situation, only LED intelligent road can go farther. For now, the direction of the LED intelligent is divided into two aspects: agricultural intelligence and optical communication. For the Internet concept is still in the mainstream of the world, the German academic and industry in 2013 in Hannover industrial exposition on the first proposed "industrial 4.0 research project", the core of this concept is the Systems Cyber-Physical (CPS), the integration of a variety of digital information, resources, products and persom, thus building an efficient and fast and flexible information, dig...
