Q:How are LED lamp quality is good or bad?

Drive power. A good driving power can guarantee a whole lamp life, theory of life LED lamp is 100 thousand hours, and the driving power of general life ranging from less than 50 thousand hours. So in order to ensure the whole lamp life, LED lamp manufacturers tell you that the driving power is very important, and it is also one of the most critical components. On the other hand LED downlight must be a constant current power supply, if using constant voltage power supply low cost will greatly shorten the service life of LED lamp. Then, how can we identify the constant current power supply? You can see several parameters, service life, light, light effect and warranty period. If the service life is longer, the quality of the power supply will be relatively better.

Q:Led downlight can light panel directly with intelligent dimming Mody?

The lights can only be switched on, because the way LED works is different from ordinary incandescent lamps, and dimming panels designed for incandescent lamps cannot hold LED. If you are using the lamp holder and driving split LED light, you can choose an output voltage, current, the same, to support dimming drive to replace the original driver, in order to achieve dimming

Q:LED lamp power off why would light up

The distribution of capacitor connected switch contacts of parallel line formation (originally existed), after turning off the switch can still trace by alternating currentYou used a small light source lamp power LED lamp (mA current to shimmer)The combined effect of the above.

Q:Excuse me, how many different sizes for LED lamp lumens

Ha ha, we should consider the problem of heat dissipation, ah, is the light will heat

Q:LED ceiling lamp and LED downlight what is the difference

LED is a kind of lamps downlight than ordinary lamp with light, usually used for general lighting or auxiliary lighting.The LED spotlight is a highly focused luminaire with light rays that have a specific target to be specified.

Q:What is the size LED downlight

LED lamp size generally have 6 inch, 5 inch, 4 inch, 3 inch, 2.5 inch, inch inch refers to here, refers to the inside of the reflection cup diameter.The commonly used standard size and parameters of LED downlight:2.5 inch LED lamp size parameters of hole (phi 80) - page table size Phi 102 * H30 power 3W;3 inch LED lamp size parameters of hole (phi 90) - page table size Phi 112 * H30 power 5W;3.5 inch LED lamp size parameters of hole (phi 100) - page table size Phi 122 * H30 power 7W;4 inch LED lamp size parameters of hole (phi 120) - page table size Phi 146 * H30 power 9W;5 inch LED lamp size parameters of hole (phi 150) - page table size Phi 180 * H30 power 12W;6 inch LED lamp size parameters of hole (phi 160) - page table size Phi 190 * H30 power 15W;LED downlight is a kind of embedded lighting ceiling light shooting style.

Q:How much is the general 15WLED lamp luminous flux.

Of course, can also use 30142835 beads to do warm (below 4000K temperature) will be low, cool (above 6000K temperature) will be higher

Q:The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages

Fast response speed: LED fast response, completely eliminates the shortcomings of traditional high voltage sodium lamp glow process.However, we are called integrated downlight is not really "integration, although has been done in the" light "and" light body "development, but also the driving power. The general driving power supply is an external electric box, because of the larger size, the insulation shell and packaging will increase the cost.

Q:The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide

The average height is around 45mm-60mm. If your space height is greater than 60mm, you don't have to worry.

Q:The general living room to Amdo large size of the lamp?

Now more and more office and family on the use of LED lamp lighting, size depends on the specific size of the size of the living room, the living room, a dozen centimeters can, do not need too much.Because of the more and the applicability of the LED lamp used in indoor lighting more people know, is becoming more and more popular. becauseLED has some other lamps downlight incomparable even other LED lamps can not compare the applicability of indoor lighting LED lamp does not occupy the indoor space in the indoor installation of LED downlight, because hidden lamp, do not use the pressure. Forced feeling, on the contrary will produce a warm effect.So you can choose to install multiple lamp decoration lamp, reduce the pressure of space. A sense of urgency.
