LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

LED FILAMENT LAMP BULB 4W B TYPE NEW DEVELOPMENT

Q:What are the characteristics of LED bulb?
Life is more than ten times longer than incandescent, power consumption is 1/2 of ordinary light bulbs, fast response, generally 10-7 - 10-9s, color clear, recognizable performance, good vibration resistance, now the price of LED lamp is relatively high
Q:LED bulb w can replace 40W incandescent lamp
The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
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:What is the 15 Watt lumen of the LED bulb?
In general, every W is 60 to 100lm, the average is about 80lm, 15W is about 1200lm
Q:What is the AC voltage of the LED bulb?
The LED lamp is either a constant voltage drive or a constant current drive without AC voltage. Generally through the drive circuit filter rectifier, LED bulb bulb voltage is about 10V. Add: different drive circuits, different amounts of LED chips, the final voltage is different.
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!
Sandblasting can be transparent, light is not dazzling,But will still see the light...
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:LED bulb bulbs, do you need 3C certification now?
LED bulb is not required to do 3C certification, and can not do 3C certification, LED bulb is a light source, not lamps, there is no company's LED bulb made 3C, CQC done there.
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:What's the reason why LED bulb gets a lot of heat?
If the radiator has a large radiating area, the temperature is low
