The Operating Principle of LED Flood Lighting

LED flood lighting is a kind of functional lighting fixture, whose light beam is wide and average without strong directionality. When lighting up objects, the weaken speed of beam is very slow so as to give birth to a soft and transparent lighting effects. So far, LED flood lighting is widely used in outdoor environment illumination, such as for billboards, building contour, public squares, sport stadiums, factories, railway stations and harbors, etc.

What is the operating principle of LED Flood Lighting? Ultimately, it is one of LED light fixtures, which is made from semiconductors, including GaAs, GaAsP, AlGaAs and so forth. It is just a process to convert electric energy into luminous energy. It is constituted by N layer from N-type semiconductor, P layer from P-type and the active layer in the middle. After added forward biased, the electron holes in P-type area diffuse towards negative direction and enter active area. Meanwhile, electrons in N-type area diffuse towards positive direction and also enter active area. When the electrons and holes combine together, the fixture will give out light spontaneously. We always see different colors of light in the street, red, orange, yellow, green, blue and so on. How does it form? It's owing to different materials. In addition, LED light fixture would become much brighter with the increase of positive current. In a word, the stability of LED light beam is affected by the stability of current. 

The Introduction of LED Lighting Category

The Ecosystem for LED High Bay Lighting in Alibaba

 
The ecosystem in Alibaba is it's free to open a store, and when there are many LED Lights sellers they will be charged. We can't blame the platform for making profit, but the profit point in this platform is too cruel. Because the reality is if you don't strive for a sell, customers cannot see your led high bay lighting products at all, so you can either fight for it or you sell with cheap prices.
For physical stores it's easier for customers to identify the quality in led lamps stores. But on Taobao it's not the case, you can only see photos. Others sell LED flood light for only ten yuan and delivery free, and if you sell it at 50 or so, who will buy it? Does the customer actually know led chips? Do they know the material of lamp shade? It's useless to say too much, unless you are big brands like OPPLE. The customers would say your products are the same, why is yours more expensive, I would just go to other stores.
So everybody just sell at low prices. And the sales strategies everybody use? Choosing LED Lighting key words, hiring professional photographers, making up sales volume and opening Direct Train service. When the sales volume and comments reach a certain level, the sellers will apply for other group selling activities. But, have they really earned money? Only hustle and bustle.
