Light Distribution Curve

Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: PDT flame retardant plastic, good heat dissipation, flame retardant effect, you see is not very good?

Q: Where can LED bulb be used?: LED bulb is generally civilian, living room, study room, kitchen, bathroom and so on

Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?: PC Ivory lampshade, because of the low price, it is recommended to use light diffusion cover, so this should not be the problem

Q: What's the reason why LED bulb gets a lot of heat?: LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different

Q: Ordinary lamp LED bulb can?: As long as the inside of the interface is the same, for example, the E27 interface (ordinary spiral, that can be installed energy-saving lamps) installed there is no problem, LED bulb is now a lot of 110V-220V high voltage power supply, so the stability is very strong, the key is to save electricity, saving seventy percent than the energy-saving lamp, no effect, ease of use.

Q: What's the cause of the noise during the aging of LED bulb bulbs?: Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.

Q: How to identify Ic constant current LED bulb?: Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.

Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!: If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.

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: 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
