Bulb (Omnidirectional Light Distribution) / C21BB-IE

Light Distribution Curve

Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?: The chip may damp, no air humidity warehouse management process; or the chip in the assembly process by foreign influence, the lampshade is removed, and then measured once in the color of the aluminum plate radiator

Q: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb: The light produced by the three is different. From the lighting point of view, incandescent light can generally emit yellow light, and energy-saving lamps can not only send yellow light, but also white light, etc., and LED lights can be issued according to the needs of a variety of light, decorative lighting is very good.

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!: The most direct and simplest answer is the power problem.

Q: LED how does the bulb return electricity?: A 0 ohm resistor with a large point on the negative electrode

Q: What's the cause of the noise during the aging of LED bulb bulbs?: The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.

Q: How does the LED bulb go with the power?: voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,

Q: What advantages does LED bulb replace energy saving lamp?: More importantly, 3W's LED light can replace 15W's energy saving light

Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?: 60: diameter 60mm (metric unit) MR16: diameter is 16*1/8*25.4mm (Imperial units), although refers to the diameter, but the height and other dimensions are also prescribed

Q: Is it possible to manually weld LED bulb bulbs?: You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off

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.
