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 heating temperature of 65 ° high
- Hard to say, if the lamp cooling measures do a good job, that is to say, the source of heat to go smoothly through the shell powder, lamp shell 65 degrees, then, should be ok.
- Q: Why turn off the switch and dim the led lamp
- A common cause of ED lights flashing and the solution: After turn off the power supply LED lights flashing, check the switch control is zero. If the correct wiring may refer to the following methods: The human eye can generally perceived frequency of 70 Hz light flashing, higher than the frequency does not perceive. So in LED lighting applications, if the pulse signal frequency is lower than 70 Hz low frequency component, the human eye will feel the shine. In the specific application, of course, there are many factors may lead to LED lights flashing. For example, in an off-line low power LED lighting applications, a common power supply topology structure type is to isolate the flyback topology. In accordance with the "energy star" solid-state lighting standards from line 8 w LED drive GreenPoint ? reference design as an example, as a result of the flyback voltage stabilizer sine square wave power conversion did not provide primary offset constant energy, dynamic self-supply (DSS) circuit may activate and trigger light flashing. To avoid this problem, must enable primary bias to partial discharge in each half cycle, accordingly, need to choose appropriate constitute the bias circuit of capacitance and resistance value.
- Q: Shoot the light and tube light have what distinction, that is better?
- First above to distinguish from the product performance: LED tube light is a light shot inside the embedded in the ceiling lighting lamps and lanterns. 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.
- Q: Led lamp light source plate can change yourself?
- If sure just light bulb is broken, if change is not very troublesome, then change the light bulb, because the lamp you use isn't a long time, you can buy a light bulb, because they are for my own household, expensive with the cheapest price
- Q: The LED lamp aging is what mean
- Aging, sophisticated, right is to make the structure of lamps and lanterns, electrical, light up each other and so on various parts, to adapt to each other. Is in the environment of lamps and lanterns lit 48 h bai, how current is too large, as large as in actual use is aging, 220 v to 220 v, 12 v, 12 v, according to the actual application environment to do is ok!
- Q: Led courtyard lamp long good or single head
- Long exposure area is better than single head relatively wide some.
- Q: How to distinguish the LED lamp wattage?
- Look at the power input voltage and current, multiplication is the wattage.
- Q: Cob lamp and led lamp that electricity consumption big?
- The LED lamp advantages: 1. LED lamp use in low voltage direct current (dc) drive: has the advantages of small load, interference of low use environmental requirements. 2. The LED lamp can well control light spectrum, which can effectively used in the museum and gallery in local or accent lighting. 3. The luminous directivity of LED to shoot the light is very strong: brightness attenuation is much lower than traditional light, LED lamp price. 4. LED lamp very fast response time: in microsecond, as long as the switch is opened, will soon be bright, there will be no delay and flicker phenomenon. 5. The LED light that shoots the light energy concentration is very high: focused on smaller wavelength window, high purity. 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.
- Q: The 4 w LED shoot the light, can make the lamp of the study? Reading a book with
- no Is too small After a long time eyes will be very uncomfortable
- Q: Led to shoot the light is broken how to change
- Now turn off the lights switch (for safety) had better be to turn off the total power supply, and then into the drive power line (also can be directly cut short), then remove the bad driver And then put the new drive power input skin, two light thread dial the skin. Let one of the root drive power cord wrapped around the lamp power cord (chaozhou both positive and negative), on the one of tie up good, good electrical tape, another root connection same good tangle on electrical tape.
