What Is the Difference Between Cheap LDE, Etc. and Your LED Light?

The LED lamp has a lot of categories, typing is troublesome, and the simplicity is divided into two categories.. One is the light source, mainly the effect of spotlights, lamps, street lights, etc.. The other is the role of lanterns, mainly changing lights, shaped lights, floor lamps, etc. to decoration and lighting.. Decorative or finished lamps, expensive and cheap differences are well understood, such as chandeliers, one side of the K9 crystal chandelier, one side is ordinary, even glass, gum, etc., the material is not the same, the price is not The same, I don't start the details, the landlord should not ask this.. The LED is a wafer that can convert a solid-state semiconductor in which electrical energy is converted into light energy.. One end of the wafer is a p-type semiconductor. The other end is an n-type semiconductor. When the current passes this wafer, the electronic N-type semiconductor will be pushed to the p-type semiconductor, and when the n-type semiconductor electron is met, the P-type semiconductor electron meets. Energy will be issued in the form of photons, this is the principle of LED lights.. The wavelength of light is also the color of the light, which is determined by the material forming the P-N knot; the core of the LED light is the LED luminescent crystal / chip.. The chip passes through the process manufacturing process such as Lei wafer, steamed plating, etching, polishing, causing how much PN electrons in the chip, PN electrode scratches, etc., the size of the conversion rate of the wafer is changed, and there is a difference in brightness. Some conversion rates are brighter, some low, we call it naked brightness. In addition, each wafer has a decrease in decrease, that is, the efficiency of the electrical energy conversion into light energy at a certain period of time is more stable; theoretical wafer effective life can reach 100,000 hours.. After the chip is completed, there is also a package, that is, make the LED chip to the lamp beads that can be seen in the daily LED lamp.. The function of the package is to protect the LED chip, and the light is transmitted, and the heat generated by the illumination is released.. At present, there is currently a positive, flip process, COB-type package, power packages, etc., different packaging processes, LEDZ final price will be different. Secondly the same package structure, the finish control of heat dissipation and stability Z is different, and the price will be different.
