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 difference between floodlight and LED to shoot the light
- Floodlight lighting shoot area/power than shoot the lamp to be big, have waterproof function.
- Q:Ordinary household lighting (building), just connected the light is bright, is a little dark light, the switch is closed, I tried to take lamp to another building, light is no problem, family line which place is wrong?
- Switch to the zero line, should be a wire into the switch, do you have the leakage floor on a line, so it caused the leakage current, the LED can shed light on small electricity.
- Q:How to adjust the light in the home
- See shoot the lamp to drive quality Big drivers are generally produced, performance is strong, the quality guaranteed. Small factory drivers are generally purchasing finished product driven, quality is uneven. 3: check the lamp parameters 1. The main parameters of LED lights, especially in high power LED lamp bead has a luminous efficiency and color rendering index, index of the luminous efficiency is 80-100 LM/W, must be greater than 80 LM/W, but the indicators are in growth, next year will reach 100-120 LM/W. Color rendering index is 0.8, the index is unnecessary to pursue more than 0.85, unless you are engaged in painting on color high requirements of the job.
- Q:How do I get the light
- Shoot the lamp to generally have a lamp holder, transformer, lamp cup plug into the socket, lamp holder line received 12 v low voltage output from the transformer online, on the other side mark 220 v line and zero line. Under normal circumstances, the power supply lines to diameter need to match, according to the total wattage lamp don't overload, easy to cause line heat causes fire hazards. As for the integrity of the design and decorating can such as first place, and where there is injury can mend the great white, scratch putty in general. (this is simpler, prevent the remodeling of large area)
- Q:How many W LED lamp can replace 50 W halogen lamp?
- Usually leds efficiency 2-3 times that of halogen lamp, then according to this number is 18 to 25 w leds can replace.
- Q:Sitting room condole top round with tube lamp or LED lamp good?
- Around the ceiling? The lamp is uniform or around the focus, if it is for certain part emphasized by ordinary halogen light cup, more can a rendering;
- Q:The sitting room decorate, LED to shoot the light with the circuit problem
- The problem and the second one, two sets of lights, switch need three lines. 4, in your family room if it is not big enough, carry empty high enough, is not recommended to do this kind of modelling, personally, I suggest you the location of the bedroom window to do a strip shape, side can do curtains trough, while doing lamp chamfer, the bottom can also install lamp or tube light, my family is doing just that
- Q:The classification of the LED lights
- This should call canister light, shoot the light is with lens and PAR lights a category, you only send positive figure I guess should die cone on the back
- Q:How to differentiate between canister light shoots the halogen lamps Bean pot lamp LED lights
- Inside the tube light can be filled with energy-saving lamps, incandescent bulbs (lighting, light relatively concentrated) Shoot the lamp to shoot the light cup (decorative light that targeted) Halogen lamps, incandescent light bulbs in mixed with gas halogen element, working principle is: when the hot filament, tungsten atoms are moving in the direction of the glass wall after evaporation, when close to the glass wall, tungsten vapour is cooled to about 800 ℃ and halogen atoms together, form a tungsten halogen tungsten (iodine tungsten or bromide). Tungsten halogen continues to move up to the central tube, is back by oxidation of filament, because halogenate tungsten is a very unstable compounds, again after the encounter heat into steam and tungsten halogen, tungsten and deposited on the filament, make up for the evaporated parts. Through the recycling process, the service life of heater not only got significantly longer (is almost four times that of incandescent lamp), at the same time because of the filament can work at higher temperatures, resulting in a higher brightness, higher color moderate higher luminous efficiency. Dared light: light source of lamps and lanterns of the tank to look like a bucket shape, has 2, 3... Led lamp is energy-saving lamps which we said
- Q:Could you tell me how many watts of the led warm yellow light can be 30-50 w halogen lamp and concentrated and astigmatism reflect the same effect? My house seems a 50 w halogen lamp, I would like to change a batch of leds. But hope for light effect is the same, the price is not the problem, but must be good quality, low light failure
- Instead of a 50 w halogen lamp, it will be with 6 w and 8 w LED lamp, LED basically see how high light efficiency, ensure that the total lumens is about 350 lumens, color temperature 3000 k, the better light Angle of 30 degrees, that can ensure the lighting effects.
