The cob spotlight is a spotlight that uses a COBLED light source as a light source. The traditional spotlight source adopts halogen lamp and high-power LED. The halogen lamp has low luminous efficiency, relatively low power consumption, and the temperature of the irradiated environment rises, and the service life is short. However, the high-power led partial light effect is too strong, the spot is uneven, and there is darkness. Where. LED is far superior to traditional lighting products in terms of lighting principle, energy saving and environmental protection. Moreover, the unidirectionality of LED illumination forms the perfect support for spotlight distribution.
(1) The light source of the cob spotlight allows people's eyes to be very well protected, especially the eyes of friends with myopia.
(2) The electricity cost per day is small, energy is saved, and the cost of producing and using electricity is saved.
(3) The installation of the cob spotlight is simple and takes less time.
(4) The light source of cob spotlight is the best cob light source at present, and it is also the mainstream trend of the development of China's lamp era.
LED spotlight introductionLED spotlights are spotlights that use light-emitting diodes as a light source. Conventional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively high power consumption, increased temperature of the exposed environment, and short service life. LED light sources are far superior to traditional lighting fixtures in terms of lighting principle, energy saving and environmental protection.
1. LED spotlight can be driven by low-voltage DC: it has the advantages of small load and weak interference, and has low requirements on the use environment. 2. LED spotlights can better control the composition of the luminescence spectrum, so that it can be used well for local or accent lighting in museums and exhibition halls.
3. The illuminance of LED spotlights is very strong: the brightness attenuation is much lower than that of traditional light sources, and the price of LED spotlights is civilian.
4. LED spotlight response time is very fast: in the microsecond level, as soon as the switch is turned on, it will light up immediately, without delay and flicker.
5. The concentration of light emitted by the LED spotlight is very high: it is concentrated in a small wavelength window and has high purity.
6. The life is very long, generally between 50,000 and 100,000 hours. Because LEDs are semiconductor devices, even frequent switching will not affect the service life.
7. Good environmental protection, LED spotlights do not add "mercury" in the production process, do not need to be inflated, do not need glass casing, good impact resistance, good shock resistance, not easy to break, easy to transport, very environmentally friendly, known as "Green energy", the price of LED spotlights is civilian.
8. Energy-saving, the spectrum of LED spotlights is almost entirely concentrated in the visible light band, and its luminous efficiency can reach 80-90%. Most people think that energy-saving lamps can save 4/5 energy is a great initiative, but LED spotlights are even more energy-saving than energy-saving lamps, which is a greater reform of solid-state light sources.
