LED display screens and LED electronic display screens are increasingly appearing in people's vision, and LED lighting has also been tested on some main roads with LED street lights. What conditions do LED street lights need to meet?
(1) Energy saving has the characteristics of low voltage, low current, high brightness. LED lamps used as LED street lamps must have the characteristics of low voltage, low current, and high brightness to ensure normal use and efficient energy conservation during installation.
(2) New green environmental protection light source, LED uses cold light source with low glare and no radiation. It does not emit harmful substances during use. LED has better environmental benefits, with no ultraviolet and infrared rays in the spectrum, and can be recycled. It does not contain mercury and is safe to touch without pollution. It is a typical green lighting source.
(3) Long service life. LED street lamps require continuous use and require batch replacement, which is also troublesome. Therefore, long service life is also an important factor in the selection. The basic service life of LED lighting lamps produced by Shenghao Optical Display is over 50000 hours, fully meeting this condition.
(4) The lamp structure is reasonable. LED lamps will completely change the structure of the lamps. According to different usage requirements, the structure of LED lamps will increase the brightness again through rare earth under the condition of increasing the initial brightness, and the luminous brightness will be further improved through the improvement of optical lenses. LED is a solid state light source packaged with epoxy resin, and its structure does not have easily damaged components such as glass bulb filaments. It is an all-solid structure, so it can withstand shock without being damaged.
(5) The light color is simple, and the light color is multiple. LED street lights used as street lights must have a simple light color and do not require too much noise. It is necessary to ensure both the lighting brightness and road safety.
(6) High security. LED light sources are driven by low voltage, with stable emission and no pollution. There is no stroboscopic phenomenon when using 50Hz AC power supply, and there is no ultraviolet B band. The color rendering index Ra is close to 100. The color temperature is 5000K, which is closer to the sun's color temperature 5500K. It is a cold light source with low heat output and no thermal radiation, and can accurately control the light type and luminous angle, with soft light color and no glare; It does not contain substances such as mercury and sodium that may harm LED street lamps.
