- Q: LED living room ceiling lamp has sectional dimming and stepless dimming, which is good? What kind of power saving and low energy consumption?
- LED ability is energy-saving, but also dimming, this is not to turn the power of thermal energy to go? Is it still energy efficient? Personally think that the relative points of the section of the bar, paragraph well, that section of electricity, of course, the province.
- Q: LED ceiling lamp, why is the light still dark after the power is switched off?. Is this power consumption?
- As long as the light in light, is in power, not just energy let it shine, eventually consume electricity (but very small, that monthly 2-3 degrees)!There are several possibilities for this:First, the switch leakage, that is not completely closed; then you have to switch. How do you decide? - will you remove the connecting line of the switch and do you see the light on one side? If you do not turn on the light, switch is still light. It is the following two;Two, AC line parallel or twisted wire induction, can only let the line alone go, difficult, and endure the recognition of it;Three, a similar, is a built-in indicator light switch, the indicating lamp circuit and electric appliances in series disconnect switch, indicator lights indicating switch position - remove the function of it, solve the problem of dark bright also turn off the switch.
- Q: LED ceiling light mounted in the living room, with subsection and remote control. The first paragraph (the first switch) all lights are blue (color change);
- If the switch is open properly, the switch is proved to be no problem.The sectional remote-control switch can normally control the remote circuit, and the receiver has no problem.It is estimated that the relay on the circuit board above, or similar relay aspects of electronic components.If you still have questions, ask again!
- Q: LED annular patch ceiling lamp used less than half a year, a few days ago suddenly become very dark, what is the reason, how to solve?
- LED lamp, crystal quality, size, and is related to the power supply, need constant current and constant voltage, light is not serious, the constant current tube is not the quality of the solution is to change the lamp, but the power is not good, so we should change the power, but need to support, so, or change the lamp,,,
- Q: With a twelve volt transformer and led how to do small beads
- If it is an inductive ballast, it also needs to be illuminated before it can be lit. At the same time, the effective illumination angle of the ceiling lamp is 180 degrees. For the 360 degree fluorescent lamp tube, about 1/3 of the light is wasted
- Q: LED ceiling lamp, why is it bright after closing the switch?
- Many people say that the off switch, lights and light or flash, actually not electrical wiring or lamps, energy-saving lamps and LED lamps are now popular, after a long line switch, power capacitor through the line of arrival between the lamp, accumulated to a certain voltage, the starting circuit light bulb. The resistance of a 470K ohm can be connected at the 220V entry line of the lamp holder to release the induced current, so that the problem of the light or flashing of the lantern can be effectively prevented. I also have electronic hobbies, LED lamp house flash is using this method to solve, some people say I don't agree with the capacitor, capacitor voltage because of problems, once the breakdown, short circuit will cause tripping, the resistance will not.
- Q: Led ceiling light is OK?
- LED ceiling lamps from the use of perspective is very good, it is a kind of using LED as a light source, installed inside the room, design lamp is the upper than the flat mounted close to the roof, as adsorption on the roof, so called LED ceiling lamps.
- Q: LED ceiling lamp, thunder will burn it?
- LED lights, like other lights, have no grounding, and there is no grounding.The so-called grounding is generally designed to use the electrical network input terminals, to prevent leakage of electrical appliances wounding. Some grounding purposes are designed to prevent electrical interference.The lightning protection design is special, but it can only play a protective role within the limited range of lightning intensity.
- Q: Approach to LED ceiling lamp wiring method
- The two white lines driven by the LED are separated, one is connected with the driver, the other is connected with the yellow, and the other drivers are connected to the blue line of the white line. You have 4 drives, and the split switch has only 3 wires to control the 3 lights. The split switch is to turn the 4 lights on respectively (remote control, click on a light bar, press 2, then light one, then press full light)
- Q: how is the LED ceiling lamp lumens
- Because of the luminous angle and so on, luminous flux is not the only standard to measure the energy saving of lamps and lanterns. We usually use light distribution and vertical illuminance to measure the substitution ratio between two lamps
