Q:Led what's the flash of the bulb?
I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power problems
Q:LED can the bulb be used in the bathroom?
of couse Yes, but LED kitchen and toilet light is recommended
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:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
Heat conductive adhesive is best.Heat conductive adhesive, also known as thermal conductive silica gel. Organic silica gel as the main body, adding fillers, thermal conductive materials and other polymer materials, mixed by silica gel, has better thermal conductivity, electrical insulation performance, widely used in electronic components. Also known as: thermal silica, silicone rubber, silicone heat, thermal conductivity of silicone. The accelerator is used to solidify a transformer, transistor, and other heating elements onto a printed circuit board assembly or radiator
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Anti torque test is carried out using only suitable for torque meter, torque test, lamp holder should be firmly bonded on the lamp or lamps used to purchase spin spin out parts, E26 and E27 for 3N*m.
Q:Are there any differences between negative ion bulb and LED bulb?
The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.
Q:Where can LED bulb be used?
Led bulb is now commonly used in civil products, is the most is a spherical bulb
Q:What's the difference between a glass cap for a bulb and a PC hood?
Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
Q:What brand of LED bulb is good in quality?
See shape. Incandescent bulbs are usually pear shaped, so the bulb should be pear shaped. That's easy to do. But incandescent lamps are all glass products, and because LED requires heat radiation, aluminum alloys are usually used as housings, because of their low cost, easy processing, and good thermal conductivity. The size of the aluminum shell determines the heat dissipation and also determines the life span.
