Q:Why can't the voice switch control the time of the LED bulb?

The production lights can be controlled. Where do they go to consult?

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 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.

Q:Will the power of the LED bulb grow longer and longer? Why?

The LED bulb does not become more powerful for extended periods of time.

Q:LED thread specifications for bulb bulbs?

Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q:Detailed description of LED bulb lamp

High purity aluminum reflector, radiator, acrylic glass cover, high power LED light source, high efficiency imported constant current source. 2. The bulb has high luminous efficiency and good environmental protection performance. It does not contain harmful substances, has no pollution to the environment, does not have infrared rays and ultraviolet rays, and avoids harm to the human body, and belongs to the green lighting products. 3, PC light shield, optional transparent or matte, to prevent glare and effectively protect the LED lamp, unique optical design, light distribution. 4, good color, to show a true color of things, a variety of color options, to meet the different needs of the environment, eliminating the traditional lamp color temperature depression caused by excessively high or low, the Department of visual comfort, improve the working efficiency of workers. 5, the bulb of the spiral points E27 and E40, easy installation, alternative to the traditional 65W125W energy-saving lamps. 6, the bulb is made of high quality aluminum alloy for shell production, good corrosion resistance, long service life, energy-saving effect is obvious. 7, bulb 30W installation height of 3-4 meters, 50W installation height of 5-6 meters.

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:What are the requirements of the LED series inspection specification for bulb bulbs?

Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.

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
