LED Spot Light Series

LED to shoot the light, English name is LED spotlights, 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.LED lamp is mainly used for decoration, commercial space, lighting and building lighting, etc., with the development and progress of LED technology, the market of LED lamp performance advantage is very outstanding, high purity aluminum reflector, the beam is the most accurate and reflective effect is best;Symmetrical light distribution systems such as narrow Angle, wide Angle and asymmetric etc., and the projector lamp is equipped with a scale plate, people can adjust the radiation Angle conveniently according to the scale.In addition, in order to facilitate maintenance, the LED projector lamp is replaced by a back-up switch.The lighting decoration effect is first-rate, and the LED projection lamp can realize the dynamic effects of gradual change, jumping, color flashing, random flashing, gradual change, chase and scanning.

Product superiority

1. LED spotlights can be driven by low-voltage direct current: it has the advantages of small load and weak interference, and has low requirements on the use environment.2. LED spotlights can control the composition of the luminous spectrum well, so that they can be well used for local or key lighting in museums and exhibition halls.

3. The luminous directivity of LED spotlights is very strong: the luminance attenuation is much lower than that of traditional light sources, and the price of LED spotlights is fairly civilian.

4. The response time of LED spotlights is very fast: at the microsecond level, as long as the switch is on, it will be on immediately without any delay or flicker.

5. The light energy concentration of LED spotlights is very high: it is concentrated in a small wavelength window with high purity.

6. The service life is very long, generally between 50,000 and 100,000 hours, because LED is a semiconductor device, and even frequent switching will not 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, the spectrum of LED spotlights is almost all concentrated in the visible light frequency band, and its luminous efficiency can reach 80 ~ 90%.It is generally believed that the energy-saving of energy-saving lamps 4/5 is a great innovation, but LED spotlights are more than 1/2 energy efficient than energy-saving lamps, which is a greater reform of solid light sources.
