FAQ

LED what kinds of screw bulbs are there?
There are E14, E27, E40, B22, LED bulb, only these screwsThe most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
The first is Aluminum Alloy better heat dissipation, aluminum is relatively high, and made products, together with the positive effect is not the same, in addition, the wick and the circuit there will be differences, this will also affect the application of life and feelings.
What's the cause of the noise during the aging of LED bulb bulbs?
This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.
LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
LED bulb lamp, are driven by a power of the ordinary small beads, driving is very simple only rectification, filtering, limiting the number of components is another large power SMD beads, this drive is more troublesome, SMT SMD components, and double plate, both have the element.
Can the bulb's true life reach 30000~50000 by LED?
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
Are there any differences between negative ion bulb and LED bulb?
The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.
Want to find common features, unified purchase accessories repair!
The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
What's the reason why LED bulb gets a lot of heat?
If the radiator has a large radiating area, the temperature is low
