Q: Why the LED lamp (white light) edge hair blue light shone on the wall: But so far no can emit white chips, so common technique is to use the blue color chip now covered with a layer of fluorescent powder mixed white light, so the number of the wavelength of the blue light and fluorescent powder, the uniformity of phosphor coverage on a chip will interfere with leds emit white light color, such as less phosphors may be blue, for example, the yellow, middle high edge will be blue or blue.

Q: LED to shoot the light is not very bright, or where the flash is broken?: Flash isn't lamp bead bad, this should be a drive and lamp does not match, how much is your driver output volts, current how many, what size of lamp bead, when you load series and form? I can assure you that your lamp voltage than you drive on the output voltage

Q: The PAR value of lamps and lanterns is what mean?: The PAR value of lamps and lanterns is parabolic shape of the lamp. Said is the shape of the lamp. For example, PAR20, PAR30 PAR38 said maximum overall diameter size. Such as PAR38, maximum overall diameter size of 38 (1/8) * * 25.4 120.0 mm material 38 in Britain is divided into units, the conversion relation is as follows: 1 the points = 1/8 "1 inch = 25.4 mm.

Q: Shoot the lamp to use of what brand is good? How much is a led lamp?: The led must not keen on gaining petty advantages Don't use that I hadn't heard of the name brand or brand than energy-saving lamps are cheaper The short life than incandescent bulbs

Q: What about a three-male led light?: Do not mitsuo aurora's LED professional, have a good times home on taobao mall, as if is a professional to do export before

Q: Led courtyard lamp long good or single head: Single head, of course, single head less waste,See your demand, to achieve what kind of lighting effect

Q: LED lamp PAR30 - more than 40 w hours kilowatt-hour: Another noise. Another time grew much dust accumulation, heat, light attenuation soon..Once power 1000 w, so need to 25 hours!!

Q: Excuse me how many W LED lamp appropriate gallery: Shoot the light? No, too much area light is too strong, the area is too small light is uneven. Use energy-saving lamps, the best. The story of my experience

Q: The house that new clothes builds, pick up a LED lamp Specific parameter no receive wire didn't receive zero after electrify LED lights have a dim light An estimated 10% of the after less than fully open after disconnect all electrical appliances There are light which out of the question to solve the trouble is online, etc. ~: LED lamp belongs to low pressure constant current electric equipment, want to use the power adapter when ac 220 v power supply to drive. Now the high frequency switch power supply, LED power supply is almost working frequency is controlled in 100 KHZ, input and output impedance is very high, start up easily. When turn on the fire didn't answer the zero line, power shell or internal circuit board is exposed to air, larger area to form a minor loop and outward radiation energy, cause the power weak vibration, low output voltage. This phenomenon is not obvious when the air is dry. Therefore, in order to use electricity safety and environmental protection, use LED lamps and lanterns is best according to the standard connection, namely switch must control the fire. Of course, there are still many LED lights manufacturer in order to reduce costs, using a simple capacitor step-down type power supply for the LED power supply. Because the source is a capacitive load, even after the switch wire through line can the distributed capacitance between the conduction small current, lead to LED lights dim.

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
