 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:How much led to shoot the light tile in the living room
Look at what you do with the fill light or in the background wall? Setting wall 3 watt is enough If the fill light or to select the wattage larger TB Hui xian lighting
Q:12 LED lamp power driver is good But not all bright can fix
This thing I'll fix it Will the multimeter test? Drive if I said above is normal lamp bead is broken, the multimeter diode test, bright is good, not bright either yourself in lamp bead, or directly short answer
Q:LED lamp with a period of time why will flash?

Q:The sitting room bovine eye lamp with led lamp or led the ordinary light
LED to shoot the light is better, it is the most popular energy conservation and environmental protection products, with more and more of lamps and lanterns made of LED as light source, one of the most acclaimed is LED to shoot the light, as compared with other LED lamps, LED lamp price is lower. 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.
Q:How many W LED lamp can same as philips 150 W metal halide lamp brightness?
3 x1 m billboards with 150 w metal halide lamp effect should be good, because the billboard is the reflection to the human eye, so the human eye can see clearly, so if in see billboards within a certain distance, need certain average illuminance, namely lux Lx.
Q:Household LED lamp directly on the ceiling above the glass, glass temperature is higher, matter?
Glass in general so there is no relationship.Suggestions to strengthen heat dissipation, such as increasing ventilation, etc.
Q:What is the difference between LED track lamp and track light?
Track light and LED ceiling lamp and the difference between a thing in common: Thing in common: both are LED lamps and lanterns, the shell is aluminum structure, can adjust the light Angle, to display lighting.
Q:What is the difference between LED GU10 and ordinary lamp
