Description of LED downlight

LED Downlight is designed to be rotatable 358° at horizontal and 30° at vertical direction, could meet various need on emitting directions. It is 25W including driver and delivers over 2000lm of 80+ CRI light while achieving up to 85lm/W. This outstanding performance is achieved by one 35W COB with Epistar chip. Its pending patent design especially the heat sink make sure perfect heat dissipation and low temperature on light body.

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:Turn off the lights after the bright LED lamp
Of course are,,In addition, a lamp, and if it is warm white downlight, 7W interval of 1.8 to 2 meters with a 9 watt meter interval, 2 to 2.5 meters in 1, because of the warm white Led light dark light.. If the daylight color (white) led lamp, high point to spacing of 7W or 9W, every 2 meters to 3 meters with a, above two, today I am in the company installed, the effect is very good, very bright, with a larger spacing proposal, after all Led lamp is more expensive, to avoid wasting the resources that can help you save a lot of money, today I am in the company installed 12.8 meters long * 7.45 meters wide, more than 90 square, 1.8 meters vertical spacing and horizontal spacing of 2 meters with a 9 watt Led lamp with fifteen Led lamp, brightness is bright, do not feel the need so, if you are one hundred square pavement, a lamp should be 20I hope I can help you.
Q:The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide
75mm hole, downlight height can be controlled in 3W.5W, height of about 50mm, there is a need to ask me.
Q:Now there is no replacement of the LED light source lamp?
Yes, it depends on what level you want. I can solve your problem with a net name.
Q:Excuse me, how to install the LED lamp?
Lamps shall not be covered by any flammable substanceThe wiring of the lamp should not be close to the radiator, and should be avoided as far as possible
Q:Excuse me, how many different sizes for LED lamp lumens
See customer needs and in what place, with the output of the LM itself and quality of reflective glass beads, beads arranged, there is a direct relationship between the transparent mask
Q:Common questions about LED downlight spotlights
According to your lamp data should be 4W your dimming driver is 6--12, 12V4 is only 6W output power so only one use, otherwise affect dimming
Q:LED downlight, embedded lamps, lamp tube and difference?
I. definitions1, downlightThe lamp is generally a lamp holder, lamp can be directly mounted incandescent or energy-saving lamps. Is a lamp embedded into the lighting ceiling light shooting style. Its biggest characteristic is to maintain the overall unity and perfection of the building decoration, not because of the setting of lamps and lanterns, and destroy the perfect unity of ceiling art. The recessed luminaire, mounted inside the ceiling, projects all the light downward, directly to the light. Different light effects can be obtained with different reflectors, lenses, louvers, and light bulbs. Table space, can increase the space of the soft atmosphere, if you want to create a warm feeling, can try a lamp lamp, reducing the spatial sense of oppression. Generally in the hotel, family, coffee shop use more.
Q:How to choose the right LED downlight
According to their own needs, choose the most appropriate lamps and lanterns. Although the LED lamp at this stage is not so widely used, but its development is an unstoppable trend, I believe that in the near future, it will become a more suitable light group we use, we will solve the problem of vision to a great extent.
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
