  With the development of science and technology, tungsten lamp has been gradually out of the market, we all know that the light bulb is to use the electric shade to heat tungsten wire to incandescent effect, then many friends are curious,   LED light   almost replaced the tungsten lamp, life is very widely used, how does it emit light? LED is short for  light-emitting diode , a type of semiconductor diode that converts electrical energy into light energy.Led and ordinary diode is composed of a PN junction, also has one-way conductivity.When a forward voltage is applied to the led, the holes in the n-region are injected from the p-region and the electrons in the p-region are injected from the n-region. The electrons in the n-region and the holes in the p-region are compounded with the electrons in the n-region and the holes in the p-region within a few microns around the PN junction, respectively, to produce spontaneous emission fluorescence. The energy states of ele...

  As   LED mirror   is quickly proving itself as one of the most popolar ways to introduce new, energy-saving lighting in any space, the use is on the rise. The common use place is bathrooms, now it extends to bedrooms, salons, bars, restaurants, spas, retail outlets, and hotels. What exactly is a  mirror with LED lights ? How does it add functionality and stylish in the space? What are the different kind of LED mirror light options available? We’ve put together a practical guide that will take the hassle out of transforming your space, check out our brief information below to help you get the most of your  LED illuminated mirror  experience. What is an LED Mirror? An LED mirror defines a specific type of mirror that has been equipped with an LED mirror light. A  mirror with LED lights  can provide some ambient backlighting, or a stronger and brighter shine when you try to see even the smallest of blemishes on your face. An  electric mirror ...

Which one is better, the led bead or the patch? In fact, for this problem,We analyzed the structure, power and use of  led bead  and LED patch, and got the most objective comparison: One thing you should know is that LED beads are just a general term. The power of the led bead used for direct insertion is larger, while the power of the LED patch is smaller.The welding spot of ordinary LED lamp bead is larger than that of patch, and the Angle of lamp bead can be made very small (the light is concentrated and shoots far, but the irradiation range is limited).The patch Angle is larger, so the heat dissipation and stability will be much better. Because there is no reflective cup and silica gel, the light flux will be lower. According to the power size points:  can be divided into small power, high power (the industry generally called more than 0.5W lamp high-power lamp); According to the contour points:  can be divided into direct plug-in and patch type into type led lam...
