The street lamp head has a high color rendering index, good color rendering, more realistic and bright colors, and a variety of color temperatures are available to meet the color temperature requirements of different occasions. Green and environmentally friendly, does not contain polluting elements such as lead and mercury, and does not pollute the environment. Wide input voltage, PWM constant current technology, high efficiency, low heat generation, and high constant current accuracy.
The light color rendering of LED street lamp heads is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamp heads reaches more than 75. From the perspective of visual psychology, to achieve the same brightness, the illumination of LED street lamp heads can be reduced by more than 20% on average compared to high-pressure sodium lamps.
LED is a low-voltage device, and the voltage to drive a single LED is a safe voltage. The power of a single LED in this series of products is 1 watt, so it is safer than using a high-voltage power supply, and is particularly suitable for use in public places.
LED street lamp head is made of aluminum alloy die-casting, which can effectively dissipate heat, waterproof and dustproof. The surface of the lamp is anti-ultraviolet and corrosion-resistant, and the overall lamp meets the IP65 standard; the outer cover can be made of PC tube, which can withstand high temperatures up to 135 degrees, high-strength tempered glass cover; high-power LED light source; high-efficiency imported constant current source.
1: Solar street lamp head must use LED light source. When installing the lamp head, you must consider its size, because it is installed on the bracket. If the size is too large, it will bring a lot of load to the socket, which is easy to cause safety hazards.
2: LED lamp head has no filament burning, heat precipitation and other factors, so the service life will be longer and not easy to damage. In addition, the heat dissipation effect of LED lamp head is very good. If the heat dissipation is good, the light decay will be slower. If the light decay is slow, it can be used for a longer time, that is, the life span will be longer.
3: The general lamp head has uniform light color: no lens is added, and the brightness is increased without sacrificing uniform light color, ensuring uniform light color without aperture. LED does not contain harmful metal mercury, unlike high-pressure sodium lamps or metal halide lamps, which will cause harm to the environment when scrapped.
4: The lamp head has high brightness and low heat generation. LED light source is a typical green lighting source and will not cause light pollution to the environment. Moreover, the LED light source has high brightness. Even if the brightness is very high, the heat generation is much slower than that of ordinary lighting fixtures, which is also one of its advantages.
