LED Spot Lights Optical Properties
Sep 04, 2017

LED lighting is a light-emitting diode as a light source of the spotlights. Traditional lighting more use of halogen lamps, luminous efficiency is low, more power consumption, exposure to ambient temperature rise, short service life. LED light source in the light principle, energy saving, environmental protection level are far superior to traditional lighting fixtures.

Price advantage

LED lighting it is the most concerned about the current energy-saving environmental protection products to LED as a light source made more and more lamps, one of the most acclaimed is the LED lighting, because compared with other LED lamps, LED lighting prices more low.

1.LED spotlights use low-voltage direct current can be driven: a small load, the advantages of weak interference, the use of environmental requirements are low. 2. LED lighting can better control the composition of the luminous spectrum, which can be well used in museums and exhibition hall in the local or key lighting.

3.LED spotlight luminous directivity is very strong: brightness attenuation is much lower than the traditional light source, LED lighting prices civilians.

4.LED spotlight response time is very fast: in the microsecond level, as long as the switch is open, immediately will be bright, there will be no delay and flashing phenomenon.

5.LED spotlight issued by the light energy concentration is high: concentrated in the smaller wavelength window, high purity.

6. Life is very long, generally between 50,000 to 100,000 hours, because the LED is a semiconductor device, even the frequent switch, it will not affect the service life.

7. Environmental protection is good, LED lighting in the production process do not add "mercury", do not need to inflate, do not need glass shell, good impact resistance, good shock resistance, easy to break, easy to transport, very environmentally friendly, known as "Green energy", LED spotlight price of civilians.

8. Energy-saving, LED lighting, almost all of the spectrum focused on the visible frequency band, the luminous efficiency of up to 80 ~ 90%. Most people think that energy-saving lamps can be energy-saving 4/5 is a great initiative, but LED lighting than energy-saving lamps but also energy-saving 1/2, which is a great reform of solid light source.

In addition, LED lighting also has other advantages, high light quality, basically no radiation, LED spotlight price of civilians, are typical of green lighting; reliable and durable, maintenance costs are extremely low and so on. Because LED lighting has more than other solid light source can not match the characteristics of 10 years after the LED lighting industry will be the mainstream light source.

As the LED bulb in the structure than the halogen spotlights complex, so even in the case of large-scale production, the product price will be higher than the halogen lamp. But as more and more people know and accept, and the scale of the production slowly spread, LED lighting prices will soon reach the acceptable level. If you count on the purchase of an energy-saving account, you will find that even a higher price, in the use of a year on the basis of the initial purchase cost + 1 year electricity costs are lower than the traditional halogen spotlights. And LED bulb life has been up to 50,000 hours or more.

Optical characteristics: LED provides a half-width of the monochromatic light, because the semiconductor energy gap with the temperature rise, so it launched the peak wavelength increases with the temperature increases, that is, the red shift, the temperature coefficient For +2 ~ 3A /. LED luminous brightness L is proportional to the forward current. The current increases, the luminous brightness is also increased.

Applications: LED lighting is mainly used for decoration, commercial space lighting and architectural lighting, with the development and progress of LED technology, LED lamp on the market performance advantage is very prominent, the use of high purity aluminum reflector, the most accurate beam , The best reflection effect; symmetrical narrow angle, wide angle and asymmetric distribution system, and the projection lamps are attached to the scale board, people can adjust the scale according to the scale easy to adjust. In addition, in order to facilitate maintenance, LED projection lamp behind the use of open replacement lamp. Lighting decorative effect of first-class, LED flood light can achieve gradient, jump, color flicker, random flashing, gradient alternation and chase, scan and other dynamic effects. LED projection lights and LED underwater lights, LED buried lights, LED wall washer can be used independently, can also be used interchangeably, resulting in more changes in the effect, and LED projection lamp is mainly used for single building, historical buildings Exterior lighting, green landscape lighting, the building outside the light through the lighting, billboard lighting and other special lighting facilities, as well as bars, dance halls and other entertainment venues lighting, the market development prospects.
