The Luminous Theory of LED The underlying working principle of LED is the energy level transition.   There could be several energy levels in the electron of an atom. When the electron bounces from high level to lower level,  there would be less energy of electron accordingly, and the part that has been gone from electron is transformed to be sent out as photons which a mass of them are s...

Advantages of LED Lights The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of an led lamp is a stark contrast to the average life of an incandescent bulb, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using...

Questions Analysis of High-power LED in Application This technical article analyzes twelve questions of high power LED during its application.1. Chromatic aberration Individual LED basically has no chromatic aberration problem, however, if there are a lot of LEDs being put into use, or a lamp with multiple LEDs at the same time, the problem will appear. Although like LUXEON will divide L...

LED Packaging Technique Development LED packaging technology is mostly developed based on discrete device packaging technology, but there is a lot of particularity. Under normal circumstances, the discrete device of the tube core is sealed in the packaging, whose main role is to protect the tube core and electrical interconnection. And LED encapsulation is to complete the output electric sign...

How to Distinguish the Quality of LED Unit Board? This technical article introduces the measures to distinguish the quality of LED board.Materials:  1. Panel of LED board: To compete with low price, some LED unit board manufacturer uses cheap flame retardant paper board or single fiber board as the LED PCB circuit board. This is because all-fiberglass PCB is too expensive. It cannot...

Dimmer Control Technology of DC Power LED This technical article introduces five dimmer control technology of DC power LED.1. Forward current adjustment method The simplest method of adjusting LED current is to change the current resistance which is connected with LED load. Almost all the DC-DC constant current chips have a test current of interface, comparing the detected voltage and ch...
