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:The LED lamp mainly used in what place
The LED lamp can be good for a specific position or a specific item to illuminate prominent role, in order to achieve the general LED lamp is 15 degrees, 30 degrees, 45 degree, 60 degree Angle such as illumination, like hotel, household, bars, shops, clothing stores, etc can all be used, use very extensive
Q:Do household LED lamp (70 w 12 v) an hour how many kilowatt consumption???????
Electricity is very little,0.07 watts.Is a kilowatt hours of electricity for a time
Q:What brand of shoot the lamp to LED lamp of choose and buy skills
View the lamp parameters 1. The main parameters of LED lights, especially in high power LED lamp bead has a luminous efficiency and color rendering index, index of the luminous efficiency is 80-100 lm/W, must be greater than 80 LM/W, but the indicators are in growth, to the next year will reach 100-120 LM/W. Color rendering index is 0.8, the index is unnecessary to pursue more than 0.85, unless you are engaged in painting on color high requirements of the job.
Q:Macao grams and shoot the light, to guarantee the quality goods. About 50 yuan or so
LED lamp is to use leds as a light source to shoot the light. LED light source on the luminous principle, energy-saving, environmental protection level are much better than traditional lighting lamps and lanterns. And LED the unidirectional formed to shoot the light distribution of the perfect support.
Q:The LED is low voltage and high pressure
Don't blindly pick, check whether it is capacitance step-down circuit. If it is not low pressure directly is burned out
Q:The original old how long pole to shoot the light to LED lights
The assembly Electronic transformer is fixed on the original position of lamps and lanterns, two output connecting line respectively with that of the original lamp socket is linked together, good insulation and voltage polarity on the socket, and then do the LED board according to the polarity insert inside the lamp holder, even a good power cord. Check the wiring and correct after insert the 220 v power source, the light, each with 10 v voltage measurement resistance pressure drop, use the formula I = U/R calculated through the current of each group of LED lights, as long as no more than 20 ma.
Q:Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad
Drive power supply, and good driving power can guarantee the overall life of the lamps and lanterns, LED the theory of life and the life of the general drive power supply is 100000 hours less than 100000 hours. In order to guarantee the overall life of the lamps and lanterns, driving power supply is also a key link; On the other hand must be LED constant current drive, if using a low-cost constant voltage driver will shorten the service life of the LED. As an ordinary consumers how to identify the LED driver power supply of the good or bad? See a few parameters, droop, service life, light efficiency, and quality assurance period. To provide quality assurance for a long time factory production quality LED lamps and lanterns is good.
Q:How about TCL LED to shoot the light, the price is about,
Can look at other brands! Such as leishi, philips, sunshine! They use LED chips are mostly American cory and Japan, and Taiwan wafer, quality no difference! Are all working for somebody else, there is no difference!
Q:The led lamp is suitable for reading?
To reading lamp can choose color is white, 3 w shoot the light is illuminated distance is limited, additional LED shoot the light when there is a shadow of the fluorescent lamp is not. Your room how many lamp?
