LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

Q: LED thread specifications for bulb bulbs?
Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;
Q: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.
Q: LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
Power supply has noise, it is the design of transformer, winding, the design of switch power supply.. Engineering reference..
Q: How to choose the bulb power?
LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. Have the advantage of all LED lamps and lanterns:1, energy saving, environmental protection;2, long service life;3 、 no strobe, green.
Q: Seeking the production process of LED bulb... Thanks
10 points, Baidu wants to be a LED engineer. LZ is a real budget man
Q: What are the driving IC used in LED bulb?
MT7930, LM3445MM do bulb bulb, the effect is also ok.
Q: LED bulb bulbs, do you need 3C certification now?
Simple bulb does not require 3C or CQC certification.Only with lampholders, and then judge according to the situation.
Q: LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
Q: What's the difference between a glass cap for a bulb and a PC hood?
Weight comparisonPC specific gravity 1.2,The proportion of glass (usually glass) is 2.5,That is to say, PC is lighter in weight than glass.
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.
