Q: How to choose to shoot the light: LED to shoot the light color consistency: the current domestic there are a lot of assembly house, large and small combined also have thousands of, of course, also have strong and weak points of the power. There are a lot of small assembly house because there is no testing machine, so either not testing, or outgoing. For such quality is difficult to guarantee.

Q: How much is the LED to shoot the light, color rendering index in general: > 80, we have integrated LED lamp, luminous efficiency is very good, now try shimao riverside Hilton Hotel in nanjing, you can search: the star of the EPC contract energy management, learn more shoots the knowledge well

Q: Sitting room condole top round with tube lamp or LED lamp good?: If simply on the role of lighting with leds, more energy efficient, but cost is higher (actually a year to save electricity I guess there isn't much, psychological effect is greater than the actual role). Canister light that individual is not very recommend, general tube lamp light source is energy-saving lamps, looks uncomfortable

Q: The led lamp or built-in good external constant current driver: Built-in like to drive in a work of the oven, the outer is working in normal temperature, which long life are you talking about? But some environment: such as moisture, dust environment, have to consider the external, LED lamp bead every working environment temperature 10 ℃, life will be reduced by half.

Q: 18 w changed other power drive not bright LED lamp, what reason be?: VF values of each lamp bead is about 3-3.4 V, so a series of at least 18 to 54 V, general situation, the output voltage won't do more than 50 V, because it is not safe (of course, the use of isolation was not drive), so will make it 2 and 9 series way for more than 27 V (voltage), but not see your driver clear this After a few short also cannot do 3 * 18 w, because your lights must be 1 w (300 ma), rather than a 3 w (600 ma), current headlight bead hold, within a few hours it broke

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

Q: The difference between the LED downlight and LED lamp: LED tube light is a light shot inside the embedded in the ceiling lighting lamps and lanterns. Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighting or assist illume. LED lamp is embedded in the ceiling or wall, general lighting products is a kind of highly concentrated, usually it's light to the specified target position. Through light is used to emphasize important points. The manifestation of LED lamp in key exposure position such as: TV wall, Logo background, and some important pendant accessories, etc

Q: LED lamp PAR30 - more than 40 w hours kilowatt-hour: 40 tile does not generally foot tile, about 25 hours to 30 hours once electricity. Actually I am not recommend you use the lamps and lanterns of LED PAR30.

Q: LED two head lamp lines do not short circuit is not grounded on the total trip what reason?: Should be a short circuit, first down to shoot the light, open switch, if can open, is lamp short circuit, if not is the line short circuit!

Q: Led to shoot the light is broken how to change: Now turn off the lights switch (for safety) had better be to turn off the total power supply, and then into the drive power line (also can be directly cut short), then remove the bad driver And then put the new drive power input skin, two light thread dial the skin. Let one of the root drive power cord wrapped around the lamp power cord (chaozhou both positive and negative), on the one of tie up good, good electrical tape, another root connection same good tangle on electrical tape.
