 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 sitting room bovine eye lamp with led lamp or led the ordinary light
6. Life is very long, generally between 50000-100000 hours, because the LED is a semiconductor device, even frequent switch, also won't affect the service life. 7. Good environmental protection, LED to shoot the light in the process of production don't add "mercury", also do not need air, do not need glass shell, good impact resistance, good shock resistance, invulnerability to breakage and facilitate transportation, very green, known as "green energy", the LED lamp price. 8. Energy saving, LED to shoot the light spectrum of almost all concentrated in the visible light spectrum, the luminous efficiency of up to 80 ~ 90%. 4/5 people think commonly, energy-saving lamps save energy is a great invention, but the LED lamp energy-saving 1/2 than energy-saving lamps, this is a solid light source is more great reform. In addition, the LED lamp also has other advantages, light quality, basically no radiation, LED lamp price civilian, belongs to typical green lighting source; Reliable and durable, maintenance cost is very low and so on. Because of the LED lamp has the characteristics of more than other solid light source is unmatched, 10 years later, LED lighting industry will be the mainstream of the light source.
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:Macao grams and shoot the light, to guarantee the quality goods. About 50 yuan or so
Want to good quality and low light failure products, as related to factory for the level of power and thermal design of selecting well-known manufacturers as far as possible, especially for osram, philips companies such as foundry, such basic on technology and quality are guaranteed, the price can also accept, the design of the factory do is good, is a simple test can probably understand: the lamp light up more than half an hour, touch the outside of the hardware, if very hot, that don't do a good heat dissipation, light failure will be faster, generally speaking, there are little hot is normal. LED selection is very important, import slightly better than domestic, but imports also have light failure quickly, preferably is Japan's LED chip, and then the European and South Korea, is in the United States again, finally is domestic larger (brand), do not recommend using home-made low-end LED, quality can't guarantee!
Q:What the reason, is led guide to shoot the light flashing?
this is the case, if is stroboscopic serious, is the problem of power drive. 2, no matter what the LED lamps and lanterns, there is no ballast this device! So can't be ballast problem.
Q:Excuse me how many W LED lamp appropriate gallery
Shoot the light? No, too much area light is too strong, the area is too small light is uneven. Use energy-saving lamps, the best. The story of my experience
Q:How do I get the light
Transformer is bound to pick up line and zero line, ground wire is received on the shell of lamps and lanterns, don't wrong, if it does not clear, may I ask for your electrical wiring, the so-called a wire, there is no such thing as, lamps and lanterns must have a loop
Q:Best lighting distance of LED to shoot the light
Exposure to distance over 50 cm, 100 cm, 280 cm is the best distance "Here refers to inch, TV and so on. 1 inch = 2.54 cm. namely 4 inch = 4 * 2.54 = 2.54 cm. The 10 cm 6 inch = 6 * 2.54 = 2.54 cm. That is 15 cm 8 inch = 8 * 2.54 = 20.32 cm. The 20 cm Household size of tube light general again between 60-120 - mm, the size of the chandelier is bad to say about 30-100 cm, absorb dome light from 10 cm to 60 cm, go to the market of lamps and lanterns choose according to their own situation
Q:A few questions about LED lights
1, the power supply can be theoretically the two sets of 3 w shoot the light, the output current is greater than work, but not small, not to shoot the light burning 2, the 24 v power supply can shoot the light series two such use, single pick up a 12 v lamp will certainly out of the question, the output voltage must be consistent with working voltage 3, similar to the second question, this problem only output current is bigger, can't meet, but can be parallel two groups of two series of a total of four series lamp or two to shoot the light.
Q:Ask high people to instruct the LED light maintenance method
In power, is the driver of the upstairs said, his bad repair, capacitance is the most common problems, the death of the current if light could be LED will be burn out, the whole lamp should be changed.
Q:How many watts of suitable bedroom LED lights use?
So choose 3 goods 5 watts (like bright 5 watts). Color words, is Chinese, most of them choose white or warm white, rarely with warm light, directly with the western genes related to visual effect. General bedroom to bring some warm warm have emotional appeal, easy to fall asleep.
