Q:How much is the LED to shoot the light, color rendering index in general
According to difference of each manufacturer to purchase the lamp bead and shoot the light color rendering index, general Ra between 50-90. LED white light than warm white color rendering index is relatively high, general manufacturer to produce LED lamp color rendering index in more than 70
Q:What the reason, is led guide to shoot the light flashing?
this is the case, if is stroboscopic serious, is the problem of power drive. 2, no matter what the LED lamps and lanterns, there is no ballast this device! So can't be ballast problem.
Q:How can you make the led lamp not dazzling
Initially LED is used as the indicator light instrument and then all kinds of light color of LED traffic light and display screen has been widely applied in large area, produced good economic and social benefits. 12 inches of red traffic lights, for example, in the United States could have been used long life, low luminous efficiency of the 140 - watt incandescent lamp as light source, it produces 2000 lumens of white light. After the red filter, light loss 90%, only 200 lumens of red light. And in the light of the new design, Lumileds companies adopted 18 red LED light source, including circuit loss, total power consumption of 14 watts, can produce the same light. Car light is also an important field of LED light source.
Q:LED to shoot the light on when why?
LED lamp bead quality is bad, the power supply is not stable. Try suggested a change of power supply.
Q:LED tube light, downlight, and what is the difference between tube lamp?
downlight Downlight largely refers to a way of the installation of lamps and lanterns. Downlight refers to a kind of embedded in the plane for the lamp of local lighting, recessed light to avoid general lighting, can make local became prominent in light, now decorate a wave, a lot of people like to use embedded do bedroom lighting lamp, heavy use of inside the bedroom.
Q:What kinds of leds are included?
MR16, GU10, GU5.3 lamp holder (or holder) models, are these MR16 is two needles into, low pressure, need to be equipped with a driver; GU10 and GU5.3 is high voltage 220 v. And spiral lamp holder E14 and E27, E27 is home commonly used lampholder, E14 smaller than E27. As we have the CPL lamp cup lamp holder. As for the LED lamp is roughly including LED lamp cup, LED ceiling lamp, LED downlight etc, PAR lamps and the LED lamp, LED bulb is not big. Because the lamps and lanterns of LED lamp is refers to the condenser, and the ball bubble lamp is glistening divergence.
Q:What is the difference between LED GU10 and ordinary lamp
Tube light is usually thought to be installed in the ceiling, condole commonly need over 150 mm to pack. Of the canister light, of course, there are external type. In the absence of dome light or droplight installation tube light is a good choice, relative to shoot the light wants downy light. Shoot the lamp to be generally can be divided into orbit type, hanging and embedded, etc. Shoot the light with transformer, but also have without transformer. Embedded within the lamp can be installed in the ceiling. Lamp is mainly used to emphasize or performance, such as TV wall, hang a picture, accessories, etc., can play the light rhyme to enhance the effect
Q:How much led to shoot the light tile in the living room
Need sitting room illumination range about 30-150 (1 lumen light energy distribution in each square meter position for a intensity of illumination.) . See you buy the luminous flux of LED light source, 3 watt LED lights on the market generally less than 200 lumen flux, 18 square with a light intensity of illumination is about 11.1, this is not enough, at least 3 lamp, and this is only the lowest standard, look at the TV in the living room under the film build atmosphere are ok, but want to read the newspaper reading or reception guests brightness is a little dark. Can consider to install a LED panel light above in the sitting room is and then by the wall around with a few warm color light LED lamp or tube light, this light effect is good.
Q:How many watts of suitable bedroom LED lights use?
So choose 3 goods 5 watts (like bright 5 watts). Color words, is Chinese, most of them choose white or warm white, rarely with warm light, directly with the western genes related to visual effect. General bedroom to bring some warm warm have emotional appeal, easy to fall asleep.
Q:A few questions about LED lights
First, the power supply current exceeds the LED light source of the load current, lead to LED lamp bead light failure quickly, even destroyed. Solution: 1, to reduce the input current; 2, the LED light source for more than 45 mil 3 w light bead, so each lamp bead to withstand current of 700 ma, but this time is 9 w, must increase the radiator. Second, the high voltage is bound to burning lamp bead,, the only way to avoid lower voltage, series resistance. Third, voltage and current are beyond ratings, is sure to burn, not saved. Can only cut down the voltage and current are. Method is still the same, want to directly change the power supply, either in LED series resistance voltage drop flow in the circuit
