 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 same power of cob and led lamp which is brighter
Taiwan chip is commonly used in single chip LED photosynthetic efficiency (commonly known as the single lamp) : 80 ~ 110 lm/W, under the same power chip, the greater the size (area) the higher light efficiency.
Q:Want to buy a track first and then buy several different wattage of led track light to try and see what specifications apply. I don't know between different brands and wattage led track lamp, is common
This I don't know, I shop is to use a brand, is pili, brand effect is very good.Generally places to buy track light, will have the orbit of form a complete set.
Q:With current meter how to detect the led lamp lights, bad
Ammeter is used to inspect the led lamp lights, good or bad, don't bother
Q:Do household LED lamp (70 w 12 v) an hour how many kilowatt consumption???????
One hour consumption of 0.07 degrees, a little more than 14 hours in 1 KWH.
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:The difference between the LED downlight and LED lamp have?
Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighting or assist illume. With the continuous development of LED technology, the service life of the LED tube light now generally can reach more than 50000 small. LED lamp is embedded in the ceiling or wall, general lighting products is a kind of highly concentrated, usually it's light to the specified target position. Through light is used to emphasize important points. When working, due to the LED lamp produces high temperature, so the LED lamp when the choose and buy must choose the high quality product, otherwise it will produce safe hidden trouble. Now LED lamp is mainly used for all kinds of commercial space lighting and architectural decoration lighting, etc. At the same time to shoot the light is divided into low pressure and high pressure, proposal consumer had better choose low voltage lamp, due to low pressure lamp life relatively longer, the higher light efficiency. Shoot the light of the general lighting power factor to decide, good lamp power factor can reach 0.99, but the price is much expensive. On the second place in application to distinguish: LED tube lights are mostly installed in the ceiling, above ceiling to 150 mm is required to install. Of course, there are LED tube light is of the external type. General selection in the absence of the location of the dome light or droplight to install the LED tube light, the light is slightly softer than shoot the light. The LED lamp can be divided into several categories: type, hanging and embedded, etc. To shoot the light is divided into with transformer and without transformer. That belongs to the embedded in the ceiling.
Q:What do you need for homemade LED lights
Monitor by using infrared transmitting tube to do, Projection lamp, if do you want to make sure the power supply, generally use the 9 v or 12 v dc power supply, the LED can use two methods of series and parallel mixed, coupled with the size of the resistance to control current, as long as 20 ma lighting.
Q:Led to shoot the light, how much is seven bubble of v
Due to the led constant current drive better. If direct use direct current (dc) according to the lamp bead by up to 85% of current TV university. Current or high voltage droop dawn soon.
Q:Store decoration, good track shoot the lamp to LED lamp or metal halide lamp is good?
Each have each good, save electricity by leds. The light effect is good with metal halide lamp
Q:On the ceiling lamp bulb is broken can change LED light bulb?
Yes, there are similar LED lamp. If you compare the outlet is in line with the line.
