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:Decorate the house, to shoot the light tube light a matter of choice
My house is all the husband choose lamp Customers with room is filled with all the 3 w tube light is very bright. We design section of the switch. No friend to open a group is very bright. Is out of the blue card. The pack of toilet to shoot the light is better.
Q:Does the LED light have to be transformer?
If it is a 12 v power supply, need another 12 v power supply, general ac dc, but never can directly connect the 220 v power supply.
Q:What do you need for homemade LED lights
:Can be accomplished within 15 meters of LED irradiation, 50-100 meters even traditional project-light lamp all cannot do it
Q:Help: anyone know how high power LED small shoot the light and the light band?
Conventional seven holes small shoot the light with the power of flooding into account, perhaps within 3 w - 4 w LED lights with a meter with 4-15 w, if you are buying into back slot instead of T5 fluorescent tube with the words should be within 10 to 15 w
Q:A dim light LED shoot the lamp to disconnect the zero line
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:What is the input voltage of the mr16 led?
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 with the perfect support search light
Q:27 square female clothing store need how many LED lights
On each side to install 4, 12 w track light mist tube lamp door position 3, 5-7 w tube lamp middle or ceiling of 5 to 7 w around 3-5. Had better choose the lamps and lanterns of LED high color rendering index, Ra > more than 85. The colour of this dress is more realistic. Short for English LED, light emitting diode, also known as light-emitting diode. Its basic structure is an electroluminescent semiconductor materials, is a solid-state semiconductor devices, it can be directly put DianZhuan into light. On a wire rack, then sealed with epoxy resin around, protect the internal core, so the LED of the seismic performance is good. The heart of the LED is a semiconductor chip, chip attached on a bracket, at the end of the end is negative, the other end connected to the power of the anode, the whole chip is encapsulated by epoxy resin.
Q:Led to shoot the light is broken how to change
Nails dig is commonly used in the edge of the lamp tube (position) linking to the smallpox condole top, a little bit hard pull became one! Two used to locate the wire spring clip!
Q:What are the kinds of led lamp holder?
LED lamps and lanterns of species LED lights, LED street lamp (Light Emitting Diode, Light Emitting Diode) the semiconductor lighting. It is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. It is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long service life, therefore, the LED street lamp will become the best choice of the road lighting energy saving reconstruction. LED project-light lamp, LED project-light lamp make specified by the intensity of illumination on the cliff above the lamps and lanterns of the surrounding environment. Say again the spotlight. Normally, it can aim at any direction, and has not affected by the climate conditions of structure. Mainly used for large-scale operations in mining, building outline, stadium, overpass, monuments, parks and flower beds, etc. Therefore, almost all the outdoor use of large area lighting lamps and lanterns can be seen as light. LED wash wall lamp, LED wash wall lamp, as the name implies, let the light like water washed metope, mainly is used for building decoration lighting, and used to draw the outline of the outline of a large building! Due to the LED energy saving, high photosynthetic efficiency, color is rich, long service life etc., so in 2013 other light source to wash the wall lamp is gradually replaced by LED wash wall light.
