Comparison between 3528 LEDs and 5050 LEDs: What are SMD 3528 and SMD 5050 LEDs? Here's an easy-to-understand comparison between LED chip numbers and sizes. The different numbers correlate to the different physical dimensions of the chip. The numbers 5050, 3528, 2835, etc correlate to the size of the chip in millimeters. Some LEDs are brighter than others and some give off more light per watt. The LED chip you will need will depend on your project. Read below for more information. Before you...

The prospect of SMD LED and through-hole LED industry is very good, but the good and the bad are different, and the overcapacity is serious. Due to the difference between the light-emitting mode and the ordinary energy-saving lamp, the service life of LED lighting products is longer than that of the energy-saving lamp, and it does not contain mercury, so it is easier to recycle. Considering the environmental protection and performance advantages of LED, the national subsidy policy is also...

Detail about IR transmitter, IR LED and LED receiver. An infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. It is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control. In general, the more they are in quantity and the better the emitters are, the stronger and wider the resulting signal is. A remote with strong emitters can often be used without directly pointing at the desired device. Infrared emitters are also...

Rgb led introduction Both RGB LED (RGBW LED, 5mm RGB LED, 8mm RGB LED or 5050 RGB LED ect.) and white LED (White SMD LED or Whtie Through-hole LED) are actually intended to achieve white light, but one is directly white light (phosphor) and the other is mixed with red, green and blue. Imaging principle of RGB lamps: RGB lamps are integrated with three primary colors. In addition, there are blue LEDs with yellow phosphors, and UV LEDs with RGB phosphors. Overall, both have their imaging...

LM-80 is a standard which created by Illuminating Engineering Society of North America (IESNA) to measure time-dependent lumen loss. LED and lighting manufacturers are performed proper tests in order to determine the performance of the products over time. LM-80 test can be applied to the LED package, series or modules. It can not be applied to the whole system. In other words, it cannot be applied to entire light fixture. Normally this test just for white SMD LED (2835 SMD LED type, 5050 SMD...
