The disadvantage of LED solar street lighting system is what

Incandescent light color temperature is 2400 k, which means it less blue, red and yellow. Before in the light, we burn wood or night candles light, this kind of artificial light color temperature around 1800 k, is almost entirely yellow/red, almost no blu-ray

incandescent lamp color temperature is 2. 4 million, which means it emit less blue, and red and yellow light more. Before there were lights we burn wood or light a candle in the evening. This kind of artificial light color temperature is about 1. 8 million, is almost entirely yellow/red, almost no blue light, and we are now facing this situation is completely different. According to the AMA's report, the new model at present is very popular throughout the country, and is promoted rapidly in many cities. White; Led lights, there are two problems: the first dazzling, uncomfortable. Because the leds have a narrow spectrum, there are a lot of blue light, it will be very dazzling, will make the pupil contraction. In the long wave band, blu-ray scattering in the human eye more easily than the yellow and red, after reaching to a certain extent can damage eyes. This will bring security to safe driving and walking at night. You can easily verify this, and try to look at your new washing machine or other appliances for light. You will find it very difficult, because the light makes you feel uncomfortable. Street lamp can produce the same effect, especially they have a lot of blue light, without the proper shielding. The second problem is that this kind of light on the influence of the biological clock. Research shows that: the full moon affects sleep. Light color temperature can be accurately described by the spectral content, which means that the emission of light contains many different wavelengths of light. This is to measure the incandescent light bulb in the glow of tungsten wire. However, color temperature for measuring fluorescent lamps and leds light chromatography is not very accurate. Another set of correlated color temperature ( 有条件现金转移支付) Measurement system is used to measure this type of light source. Based on human visual sensitivity to color to adjust the spectral content of the light source. Using this method, color temperature is 3 million of two different types of light source in blu-ray content will have a huge difference. Therefore, AMA believes that 3 million fewer CCTS cannot guarantee under blue light. Choosing led lamps and lanterns, led lamps and lanterns ought to be considered at the same time the accuracy of the spectral intensity of illumination. Ndash light produced by the corresponding number of each color light. Lighting the cause of health problems the AMA's official statement came very timely. Last week to update the world of artificial light brightness figure shows at night, street lamp light pollution is the main component. According to a statement from the AMA, night lighting is one of the problems caused by its effect on human health. Light have an effect on our body clock. This will have serious consequences for health. We should be in your light bulb put a warning label? In the evening, white leds light on inhibition of melatonin, is expected to high pressure sodium lamp QiangWu times than with the same brightness. This kind of high pressure sodium lamp is the lights in the past few decades the pillar. Melatonin suppression is a sign of biological clock disorder, result in a sleep disorder. Bright night also affects wildlife, such as interference of migratory birds nest and on the shore, the landmark of aquatic animals.
