Q:LED can the bulb be used in the bathroom?
Kitchen lighting bathroom and kitchen with special waterproof, but the working voltage of LED is low, LED lamp is also a big problem in the use of a water vapor environment, general heat sink should be no problem, is such as the use of aluminum shell, like plastic shell can not, because they on the cold and hot air convection cooling, casing is provided with a hole for air inside and outside the exchange, will put into the high-pressure part of water vapor driven, it will affect the service life.
Q:Choose which light bulb LED bulb is the healthiest
For home use, you can select LED bulb below 8W, with a color temperature below 3500K
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!
Power supply has noise, it is the design of transformer, winding, the design of switch power supply.. Engineering reference..
Q:Will the power of the LED bulb grow longer and longer? Why?
In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.
Q:Why can't the voice switch control the time of the LED bulb?
Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind
Q:What brand of LED bulb is good in quality?
View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.
Q:What does "A19" mean in LED A19 bulb?
A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
Q:Can the bulb's true life reach 30000~50000 by LED?
LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection. With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting. LED is far superior to traditional lighting products in light emitting principle, energy saving and environmental protection
Q:How does the LED bulb go with the power?
Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V
