Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate

LED work environment refers to the external work room temperature, LED lamps also have a working temperature, general LED lamp in the case of work, the external temperature is below 65 degrees is normal.

Q:LED bulb with what type of LED beads?

There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2

Q:LED can the bulb be used in the bathroom?

Ordinary bulbs can be used in the bathroom, the bath water, protection grade ordinary bulb is not high, it is easy to make when water vapor lamps or rust element short circuit failure and cause some accidents. The bathroom is suggested by the power supply lamp, lamp waterproof plate etc..

Q:What's the reason for the LED bulb strobe?

Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q:What's the cause of the noise during the aging of LED bulb bulbs?

The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.

Q:LED thread specifications for bulb bulbs?

Q:Led what's the flash of the bulb?

So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.

Q:LED bulb bulbs, do you need 3C certification now?

Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?

I've got my lighting engineer to give you a professional answerBecause the light barrier is selective for light waves, that is to say, the transmittance of light at different wavelengths is inconsistent. When the lamp cover is covered, the luminous spectrum of the light source is changed because of the filtering of the lampshade, and the color temperature certainly has certain change.Professional lampshade company should have the detection of the passing rate of different wavelengths. Is your lampshade provided by professional lampshade company?
