FAQ of LED Spot Light
*Why do LEDs have a higher initial cost than conventional light sources?
LEDs are made of electronic components which need to be packaged together to offer long lasting efficient light sources to the end user. Apart from the LED chip itself which has sapphire and gallium in the semiconductor, the process of packaging with materials like ceramic, rare earth phosphors, silicone, solder and gold wire add to the overall cost. White LEDs require further tests for calibration and standardisation.
*What are the economic advantages of using LEDs over conventional light sources?
Although the initial cost of conventional light sources is less than LEDs, they do not take into account the operational and maintenance cost of the lighting system. LEDs, having a longer life , reduce maintenance and lamp replacement cost. This reduces cost of labour to replace lamps and the cost of new lamps at the end of lamp life cycle. LEDs, also consume less energy. Thus the overall cost of a LED system can thus be significantly lower than conventional lighting systems. Most applications with LEDs offer a payback period as low as 3-4 years.
*What are the strategies in the development of LED technology that are helping to reduce the cost of LEDs in the future?
Some of the strategies reducing the cost of LEDs in the future are:
Reduction in the production process.
Simplification and reduction in the number of components.
Introduction of new materials.
- Q: The led lamp is necessary to use good
- Advice to choose color temperature below 4000 k, color rendering index above 80, big brands of LED products. Of course the price is relatively high, must not cheap.
- Q: The sitting room how to shoot the light off?
- Only take samples of the glass in the middle of the chimney, dial came down hard.
- Q: General how many watts of led to shoot the light, the most is how many watts
- ?Use LED panel lights, with the scale of the 300 * 300 mm, is about 10 w. Family condole with LED lights, can use 3528 light band. Wine cabinet or closet to choose LED tube light, can use 1 w or 3 w. Such as toilet, cabinet room, choose LED to absorb dome light, can choose 8 to 15 w dome light, can according to the area of economics in detail for selection. Families with LED lights usually choose how many watts is better?
- Q: What kind of transformer mr16 led lamp need!
- Need constant current drive, drive with two pins, is DC12V power supply voltage
- Q: The 3 w LED lamp color temperature is how many?
- Depends on specific manufacturers to choose what kind of LED. Between 3000 and 8000 all have, can choose for yourself
- Q: A few questions about LED lights
- First, the power supply current exceeds the LED light source of the load current, lead to LED lamp bead light failure quickly, even destroyed. Solution: 1, to reduce the input current; 2, the LED light source for more than 45 mil 3 w light bead, so each lamp bead to withstand current of 700 ma, but this time is 9 w, must increase the radiator. Second, the high voltage is bound to burning lamp bead,, the only way to avoid lower voltage, series resistance. Third, voltage and current are beyond ratings, is sure to burn, not saved. Can only cut down the voltage and current are. Method is still the same, want to directly change the power supply, either in LED series resistance voltage drop flow in the circuit
- Q: The 35 w to shoot the light with 3 w LED is not lit, use need not change the transformer?
- 35 w lamp has two kinds: one kind is 220 volts, no transformer. This cannot be used directly to get dc power LED bulbs
- Q: Led track light to shoot the light can not track meet 220 - volt power supply directly
- Led products are usually equipped with a driving power, please access to the manufacturer of driving power supply after use, so as to avoid damage to the lamps and lanterns. Power refers to the power source, a meter can amount to the output voltage. Is a kind of power conversion circuit, a so-called drive will be some form of fixed power into different voltage and/or different forms (ac or dc) is another kind of power supply, supply specific power demand of electrical appliances. So the driver himself into power after turn on the juice. Electronic products commonly used power adapter also is a kind of electronic products of the external drive. The LED chip is working in the low voltage dc, generally need to drive to provide stable voltage and the safety of current. The LED driver with built-in, there are external. Has internal drive leds is specified using power (such as ac mains, battery, etc.) through to can use. Need the external drive LED lights will be added with the appropriate power adapter (or external drive) to transfer the original power supply (such as mains, battery, etc.) to provide power LED chipset conform to the requirements of the work. If think reply results can please adopt oh O (studying studying) O thank you, if you have not understand place, please continue to reply.
- Q: Led lamp can adjust luminosity
- Can adjust, led driver power supply for the infinite light toning
- 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.
