With the development of high-power LEDs over the years, these new light sources are no longer satisfied as lamps for general lighting, and have begun to march into the blue ocean of road lighting. With the support of the government, LED street light demonstration streets began to bloom on the streets of major cities around the world. Most of these
solar street lights use relatively high color temperature and relatively high brightness. We might as well analyze the yellow light and white light from the illuminance and visual sensitivity, which one is better. So let me explain to you: the most important measure of brightness road lighting is not the road illuminance, but the road brightness from the driver's perspective (test point!). From the perspective of visual function, the main purpose of road lighting is to enable drivers to detect obstacles that may appear on the road in time and respond in time. When there is an obstacle on the road, the low brightness of the obstacle surface will form a contrast with the brightness of the road as the background, so that it can be seen by the driver in time. So, is there a difference in road brightness between cool and warm light? This is true. All currently used road surface materials have stronger reflectivity for long-wavelength light, that is to say, the red light component is easily reflected, and the blue light component is more absorbed. If you want to achieve qualified road brightness, you have to increase the luminous flux and power consumption of solar street lights. On the road with the same other parameters, the low color temperature road lighting has higher brightness in the driver's direction than the high color temperature road lighting. The safety of driving at night. Due to the yellowing effect of the human eye lens with age, the eyes of middle-aged and elderly people will become less and less sensitive to blue light. That is to say, even if the objective brightness of warm white light (or yellow light) and cool white light on the road surface is the same, in the eyes of middle-aged and elderly drivers, the subjective brightness of warm white light or yellow light is higher. That is to say, under the same conditions, warm white light or yellow light is more conducive to middle-aged and elderly drivers to find possible obstacles on the road. After the yellow light is used in street lights, it not only ensures the safety of roads and streets, but also brings a warm atmosphere; , street light manufacturers, , led street light manufacturers, street light poles, street light pole manufacturers, landscape lights, landscape light manufacturers, magnolia lanterns, magnolia lanterns manufacturers, minority street lights Yangzhou Global Solar Technology Development Co., Ltd. is a company engaged in outdoor road lighting Manufacturers, the main products are city circuit lights, solar street lights, high pole lights, , all kinds of special-shaped landscape lights, magnolia lights, Chinese lights, ethnic minority street lights, etc. Welcome to our factory for inspection and consultation to discuss business cooperation
