Q:LED lamp is mainly used in where
LED downlight with much more local hotel, shop, office, family etc..
Q:LED downlight downlight and how to distinguish?
LED lamp is composed of a group of LED lamp lines, each lamp line required voltage is very low, so it is necessary for certain circuit can directly used in 220V lighting circuit, the original quality of the circuit in the decision LED lamp life, general service life is several times more than ordinary lamp, price is high, energy saving and environmental protection. Is the direction of development, is to use the ordinary lamp bulb, is the most simple incandescent lamp, low voltage lamp with transformer can access 220V power.
Q:Turn off the lights after the bright LED lamp
Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.
Q:What is the role of LED downlight
LED downlight effect:1, it can be embedded in the ceiling, will not affect the overall beauty, more concentrated than in the past ordinary lamps.2, in fact, choose a good day Lantern is a LED lamp energy saving function, long service life, good LED will not produce ultraviolet light.Is a lamp embedded into the lighting ceiling light shooting style. Is a directional lighting lamp, only its opposite to the light beam angle, belonging to the light, light is concentrated, contrasting. More prominent objects, higher lumen, more quiet.
Q:Why use LED lamp light source patch
In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.
Q:How much is the general 15WLED lamp luminous flux.
Mainly depends on what you apply products, parameters vary.1, high-power 1W single 110-120lm to remove the loss of 1600lm2, 5630 0.5W, single 50-55lm, removal of loss 1400lm
Q:What brand of downlight is good? Please explain the reason, thank you!
Cost. From a cost perspective, the LED lamp price is about 3-10 times of the traditional lighting range, if the power of the time more than 6 hours a day, LED lighting is good, is expected about 1 years to be able to save money to buy a lamp; if one day 2-3 hours, it is not how much electricity the.
Q:LED lamp power off why would light up
LED lamp power off, will light up, this situation is normal in the 220 electric power supply situation, reason is caused by the distributed capacitance charge discharge line.Because the switch and the lamp is connected with 220V/50Hz AC power supply is normal, directly added to both ends of the lamp, the lamp work light; when closed, switch capacitor and lamp itself and the line is connected to the alternating current of 220V/50Hz, because the distributed capacitance of the charge and discharge can form weak current, the lamp will light.Solution: in the lamp circuit board input end in parallel with a pressure resistance of at least 400V of non-polar capacitor, capacity 0.05 micro method above (if the switch connection is longer, can be appropriately increased).
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:The general living room to Amdo large size of the lamp?
Look at the size of the living room ceiling. Class one is. 10 cm downlight
