 LED FILAMENT LAMP BULB DIMMABLE 4W B TYPE NEW DEVELOPMENT

Q: LED thread specifications for bulb bulbs?
Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.
Q: Where can LED bulb be used?
LED bulb is generally civilian, living room, study room, kitchen, bathroom and so on
Q: Ordinary lamp LED bulb can?
It should be clear, your point is before the lamp lights inside what, from the rectifier? LED bulb is mostly with drive, if there is no self rectifier lamp light, the best is the bulb is directly connected to the E27/E14/B22 lamp, LED lamp or light source has a good energy saving effect, mercury free lead-free, no stroboscopic, energy than traditional fluorescent lamp 80%
Q: LED bulb with what type of LED beads?
There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2
Q: What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
Can reach 90% of the light, can not see the inside of the lamp
Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?
MR is a reflector that is represented by a plurality of reflector groups, and 16 represents the maximum outer diameter of 1/8*16*25.4=50
Q: Led what's the flash of the bulb?
There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright.
Q: Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
You are not the light source, in addition to a treasure bully ordinary consumers can't tell the difference between good and poor light source, all blow themselves jingyuan. I think you can see for yourself, not necessarily expensive or cheap but wafer, it certainly can not be said. Big power of a simple 1W bar, poor beads 1-3 cents, the wafer will be 1.3-2 dollars. There are several tiles, and how much does it cost?.
Q: Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
Q: Secret LED bulb bubble price difference why so big?
Remember, cheap, no good goods, the market price of less than 15 yuan bulb said that their quality is not credible.
