Talking about the shortcomings of LED street lights solar street light-litelsolar production

The color temperature of an incandescent light bulb is 2400K, which means it emits less blue light and more red and yellow light. Before the advent of electric lights, we burned wood or lighted candles at night. The color temperature of this artificial light was around 1800K, almost completely yellow/red, with almost no blue light, which is completely different from what we are facing now. According to the AMA report, the new 'white' LED solar street light, which is currently popular across the country and rapidly popularized in many cities, has two problems: first, it is dazzling and uncomfortable. Because the light spectrum of this LED solar street light is very narrow and has a lot of blue light, it will be very dazzling and will constrict the pupils. Blue light is more likely to scatter in the human eye than long-wavelength yellow and red light, and will damage the eye to a certain extent. This creates safety issues for safe driving and walking at night. You can easily verify this, try looking directly at the indicator lights on your new washing machine or other appliance and you will find it difficult because the light makes you uncomfortable. Street lights can do the same thing, especially if they have a lot of blue light and don't have proper shielding. The second question is the effect of this light on the body clock. Research has shown that the full moon can affect sleep. Color temperature can accurately describe the spectral content of light, which means how much light of different wavelengths is contained in the emitted light. This is designed to measure the light emitted by the tungsten filament in an incandescent light bulb. However, color temperature is not very accurate for measuring the color spectrum of fluorescent lamps and LED solar street light. Another measurement system called correlated color temperature (CCT) is used to measure this type of light source. It adjusts the spectral content of the light source to the color sensitivity of human vision. Using this measurement, two different types of light sources with a color temperature of 3000K will have huge differences in blue light content. Therefore, AMA believes that a CCT lower than 3000K does not guarantee the minimization of blue light. When selecting LED solar street lights, the exact spectral illuminance value of the LED solar street light should be considered at the same time - the corresponding amount of each color light produced by the light. The AMA's official statement on the causes of health problems with lights is particularly timely, as the world's artificial lights at night map, updated last week, showed that street lights are a major contributor to light pollution. According to the AMA statement, one of the problems with lighting at night is its impact on human health. Light has an impact on our biological clock, and it can have serious health consequences. Should we put warning labels on your light bulbs? At night, white LED solar street light is expected to be five times more effective at suppressing melatonin than the equivalent brightness of high-pressure sodium lamps, which have been the backbone of street lighting for decades. Melatonin suppression is a hallmark of a disturbance in the biological clock, leading to sleep disturbance. Bright nights can also affect wildlife, for example, disturbing landmarks for migrating birds, affecting some aquatic animals that nest on the shore.
