With the rapid development of road traffic construction in China, the construction scale and quantity of highway tunnels are also getting larger and larger. Tunnel lighting has also emerged as problems such as energy conservation and safety. With the maturity of LED light source technology, domestic The lighting industry has also carried out the research and application practice of LED in highway tunnel lighting. Therefore, combining advanced control methods in tunnel lighting, using a new generation of light source with high luminous efficiency, good stability and long life will become a demand. And trends

Where is a good tunnel light drive power supply? Intelligent energy saving adjusts the brightness of light according to different time periods

Led tunnel light is a kind of light-efficiency energy-saving lamp. Light-emitting diode (LED) is used as the light source of the illuminant. It has high light efficiency and long life. It can be used for multi-purpose lighting with different mirrors. Causes glare or other uncomfortable reactions. The ballast uses overheat protection technology to ensure the life of the lamp. Imported high-purity mirror aluminum anodized material as mirror and through precise light distribution design, power factor greater than 0.9, high reflective efficiency, good light transmission, energy saving and environmental protection.

LED vs. Traditional Tunnel Lighting Source LED is a solid-state semiconductor device that converts electricity directly into light. Compared to traditional road tunnel illumination sources, LED sources have the following advantages:

(1) Low light decay: If the heat dissipation condition is good, the 10000h before the LED is positive light decay, the first 10000h light decay is 3% to 10%, and the first 50000h is basically 30%, which is far lower than the ordinary road illumination source. The light is more stable.

(2) High color rendering: general LED color rendering is about 7 0~8 0, higher if using three primary color phosphors; general high pressure sodium lamps are 20 to 35, low pressure sodium lamps are lower, so even the brightness of traditional light sources Higher than LED, but the visual effect is worse than LED, "not the brightest, but the most clear" This should be a direction for the development of LED light source applications.

(3) Lifespan: The life of LEDs is higher than that of general road tunnel illumination sources, and is now generally higher than 50000H.

(4) Price: Although the current price of LED lamp is higher than that of traditional lighting, with the maturity of manufacturing technology, its price is currently falling sharply. The price of high and low pressure sodium lamp is generally around 2,000 yuan, and its cable is auxiliary. The price of the piece is higher than the cost of the cable of the LED.

In addition, LED also has the advantages of high maintenance factor, good safety performance, no stroboscopic, energy saving and environmental protection.

Then a good LED light is closely related to the quality of its driver. As the saying goes, good horses are equipped with good saddles, and the lamps and drivers are closely related. The LED driver power supply on the market is mixed, and the price gap is huge. So how do you distinguish between good and bad?

First of all, look at the selection of materials, Bright star LED driver power supply from the selection of materials, are the quality materials that have been tested by engineers. The design is equipped with a complete design plan, with confidence for five years, the product is mainly exported, has passed CE, 3C , SAA, Rohs and other certifications, quality is guaranteed.
