Q: A transformer can shoot the light at the same time for several of the 12 v?: That should see you used to shoot the light is a few watts, and what is the power of the transformer, calculated by dividing the number of tiles in the transformer lamp wattage can know the answer, such as the transformer is 150 watts, shoot the light is five, then you can take two dozen, transformer is best not to work overtime, or life has a great influence on him. The hope can help you.

Q: LED lamp is not lit, how repair?: Open it before, it is better to measure the voltage and current through the LED and, then open it, each check all key parts: drive or power supply, LED lamp bead, change all the broken lights. And should find out the failure reasons of LED lamp bead, if flow, immediately minish the drive current. Check whether the drive is defective, also want to find out the reason, can the trim, can't repair the replacement.

Q: A few questions about LED lights: 1 power supply voltage must be the same as the load, the power of the output current is larger, can provide the greater the power, the power of the load ability is stronger, so the output voltage of 12 v, the power of the output current of 700 ma can be used for you to shoot the light. Of course, if a larger output current of the power supply can also use just a little too wasted. 2 and 3 for the power supply voltage of 24 v, most likely have to burn the load (leds and circuit component), if want to use, with a voltage divider to be available 24 v down to 12 v. 2 the output current and load is the same, but actually does not reach 350 after partial pressure and loss ma output, so 2 after decompression can not use or scrape can be used. 3 the same supply voltage is too high to buck can use until about 12 v, otherwise it will burn, 700 ma output current can meet the requirements of shoot the light. Summary: the power of the output current must load than old do line, otherwise due to the load is too heavy to burn the power supply, power supply voltage and load the same or close to, can have a little error, but the difference is too large, high voltage too much, may burn load circuit and LED (lamp), is too low, could not move or inefficient work load and the load is not work.

Q: Tube lamp, metal halide lamp, lamp, LED lamp, the difference between more than advice please!: Advantages: 1. LED Lantern Festival to environmental protection, energy saving. 2, long service life. 3, good applicability, due to the small size of the single star LED, can be made into any shape. 4, short response time, is the ns (ns) level of response time, while the common lamps and lanterns is ms (ms) level of response time. 5, environmental protection, no harmful metals, waste recycling easily. 6, colorful, color pure, narrow spectral range, and can pass the red, green, blue three primary colors mixed color into 7 colour or white light. Disadvantages: 1, the price is expensive. 2, at present can do general theory of efficiency and light efficiency also has the very big disparity. 3, at present can do life and theory of life also has the very big disparity (10 w hours). 4, there are still certain calorific value. 5, light failure can also be greatly narrowed. But through technology improvement to overcome these shortcomings can be, so even if the LED light source can not completely replace the traditional light source, but with the development of technology, must be LED the world in the future.

Q: Shoot the lamp to use of what brand is good? How much is a led lamp?: If you don't consider the price factor must be philips osram panasonic these imported brands But the price will be very expensive If you want good quality price is also reasonable price higher domestic leishi mitsuo jiamei op these is ok

Q: The service life of the LED lamp?: LED 1000 hours in use may not decay, and then begin to decay, normal service life of LED lights in 20000 hours, the leading enterprise of philips lighting LED lamp life for at least 25000 hours, maximum use of 40000 hours.

Q: What about a three-male led light?: Mitsuo aurora, price high, general business generally do not choose, relationship quality problems, has come to the product, the price is basically have no questions.

Q: Smallpox lamp is max25w LED power rating, is 25 watts: Yeah, you got a lot of light? If it is 25 w it should be very bright!

Q: What is the main purpose of LED to shoot the light? What is the difference between it and the ball lights, mainly performance and USES.: Shoot the light is mainly to strengthen lighting In order to highlight, bright-coloured Shoot the light is small Angle The ball bubble lamp is mainly used for lighting, also can do canister light source

Q: LED lamp biggest can do how many watts?: 3 w. Following is the specific features of high power led lamp product. Product specification 1, working voltage: 12 v 2, working current: 700 ma high-power lamp, the maximum power: 3 w Lm, luminous flux value: 120-120 5, color temperature range: 2700-6500 k 6, light Angle: 30 degrees 7, emitting light colors: white/warm white 8, the working temperature: - 20 ℃ to + 85 ℃ 9, the shell material: aluminum alloy 10, the service life: 50000 hours High power LED lamp appropriate beauty can be divided into two kinds: one kind of relatively large total power lamp for our products. Such as PAR lamp. Another as the light source adopts high power (1 w and more than 1 w) LED to shoot the light
