Q: LED thread specifications for bulb bulbs?: Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.

Q: How to choose the bulb power?: If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.

Q: LED what kinds of screw bulbs are there?: Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.

Q: What are the driving IC used in LED bulb?: Here are some of the models you want to know. You can contact me by mail and provide your detailed information and samples:Isolation without PFFT833S11 2.5W FT833A11 3-5WFT833B12 7-9W FT825 series 7-60WIsolation belt PFFT8900, 30W, FT8901 series adjustable light 30WFT8901B 7W, FT8901/2DD, DIP, built-in MOS, 24W adjustable lightNon isolation without PF:FT886A 7-24W FT883A 3-5W

Q: How does the LED bulb go with the power?: Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V

Q: What's the reason for the LED bulb strobe?: In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.

Q: 60W how many lumens and how many W LED bulb does incandescent bulb replace?: With a high quality LED light, 6W will be enough;High brightness compared to incandescent lamp, more energy saving.

Q: What brand of LED bulb is good in quality?: What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.

Q: 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.
