Q:Household LED lamp, ceiling lamp, when installation, both can zero wire?
Basic products such as LED ceiling lamp, the lamp generally driven by constant current power supply, input is 85-265 - v ac, so don't points are negative. Now LED3W ceiling price is in commonly between 25 and 45 yuan, never buy the sort of more than ten dollars, bought a very headache, a few days or not bright, or gradually, there will be more and more dark, our house is filled with dozens of, want to find the boss, but has no time at ordinary times, so to now also didn't go to, don't know how to say that the boss will? Cheap goods is not good, say two years is not bad, I can't see with the Spring Festival this year
Q:Shoot the motorcycle electric car led super bright headlights 12 v - 80 - v gm is what mean?
Motorcycle LED headlight 12 v - 80 - v general, that is to say, between the voltage from 12 v to 80 v. In fact, the lamp that I have ever seen, they have description: used for dc car, communication car doesn't work. What is the dc bus, it is headlight from the battery, don't have to start the engine can open headlight is dc bus. Conversely, headlight from magneto electric, to start the engine to drive headlight is communication. General car are dc bus, the working voltage is 12-16 v, therefore, said it doesn't make any sense to 12-80 - v. General LED lamps are used for dc bus, which is to work in 9-16 v voltage. And ac bus voltage is unstable, 6-80 - v may be, obviously, generally LED headlight is to use. I used to be repair, repair the car for about ten years, now is not repaired, play cars. Although not repair now, but due to fame, often have friends call me help loading or change to light the lamp of love in the past, therefore, for motorcycles and headlights are familiar with, as far as I know, now in the market can be used for the exchange of car LED headlight only one, is the "motorcycle LED headlamps M3AC", other motorcycle LED lamps are only used in the dc bus. Now the most important problem is to determine the dc car or a communication car is your car? Now generally motorcycles are dc car, car very little communication, only wh have few scooter is communication. Unconsciously played a lot of words, is equivalent to practice wubi, of course also hope to you a little help.
Q:What is the price of an led light?
The price of the LED lamp will not be too expensive. Such as watt led lamp 3 watt price 25 yuan. And some of the philips led to shoot the light 3 w is 65 yuan.
Q:The service life of the LED lamp?
In theory LED (single light emitting diode) life can reach 100000 hours. But after assemble into lamps and lanterns, also related to the life of the other electronic components. Also is the life of the LED lamps and lanterns of less than 100000 hours might fail, is not necessarily the LED itself, it is possible that the power of the chip, electrolytic capacitor and other components out first. And now many LED manufacturers, the quality is good and bad are intermingled.
Q:What is the difference between LED GU10 and ordinary lamp
LED lamp is to use leds as a light source to shoot the light, the traditional lamp used more halogen lamp, luminous efficiency is lower, more power consumption and environment temperature rise by illuminate, service life is short.
Q:How many W LED lamp can replace 50 W halogen lamp?
Actually this question is complicated because you wrote "alternative" is called brightness, so with trade terms means to lumen for the LED lamp under the condition of power, then you will know that 50 w halogen lamp lumens value is how much, to know that power must first know what is this light that shoots the light
Q:Led lamp and cob light which is suitable for hanging the sitting room
COB is a new way of LED packaging Belong to the point light source Condole with canister light
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:Motorcycle lens and the LED lamp can be installed at the same time, and shall not affect the circuit?
You increase the total power of about 155 w these lights, has exceeded the design of the general domestic 35 w, even though the battery, ignition key switch and headlight switch contact capacity is limited, so the best way is to add headlight relay, let the headlight received battery anode current directly through the relay contact, ground also another bold lines; Relay coil by the headlight switch control in order to extend the life of the ignition key and headlight switch contact, can avoid and round headlights lines within the original wire resistance pressure drop, and its heat. Small appliances is the electromagnetic switch, coil current through the magnetic drive large current contact, such as selection of 12 v dc relay contact current for 15 ~ 20. A, you can load 180 w ~ 240 w lamps. Also have to consider your motorcycle engine and rectifier charger whether can satisfy the requirement of the 20 ah battery charging, so as to avoid the battery often lose electricity scrap.
Q:How much is five inches square led high power lamp
Due to the small shoot the light can be combined free transform perspective, lighting effect. Shoot the light is downy, elegant, its also can local lighting, foil atmosphere
