 LED FILAMENT LAMP BULB DIMMABLE 4W B TYPE NEW DEVELOPMENT

Q: LED bulb with what type of LED beads?
Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
Q: Seeking the production process of LED bulb... Thanks
First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
Q: LED how does the bulb return electricity?
What is reflow? Never heard of it. I am a lighting technician
Q: What is the 15 Watt lumen of the LED bulb?
The chip is better, but it's also 80lm/w's light effect, so the 15W flux is 1200lm's.. The chips are even lower
Q: What are the types of LED bulb?
According to the radiator shell to points, can be divided into plastic shell, aluminum radiator and ceramic shell, in general, the ceramic shell heat radiator is best, but the price is relatively expensive, the widespread use of aluminum shell, moderate price, good heat dissipation performance
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: Choose which light bulb LED bulb is the healthiest
For home use, you can select LED bulb below 8W, with a color temperature below 3500K
Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
LED bulb: directly driven by not using AC-LED light source, light effect of the whole lamp life (compared with driving security; some) integrated LED relative heat transfer to the high requirements, high cost, simple assembly, do a single power source in low cost, high light efficiency.
Q: Want to find common features, unified purchase accessories repair!
The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
Q: How did the trademark on the LED bulb go up?
And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
