Lithium battery of solar street light prices

Since 08 white LED the luminous flux over 100 lm/W, the national each city street lamps before the high-pressure sodium lamp with new LED lights. The cost of the reasons behind the city, LED street lamp power consumption is generally half of high pressure sodium lamp power consumption, and the service life of the latter is a former

as a result of white light leds luminous flux in 2008, more than 100 ml/tile, every city throughout the country in a new light emitting diode lamp to replace the previous street lamps of high pressure sodium lamp. The reasoning behind this is cost. Led street lamp power consumption is half of the ordinary high pressure sodium lamp, the service life of the latter is twice that of the former, greatly saved the city costs, relieves the problem of shortage of electric power city. However, many people feedback is unsatisfactory. They said that white led street lamp is too bright. Previously, high pressure sodium lamp to the city or yellow light, but light emitting diode lamp has different frequencies of light, a dazzling white light. Of high pressure sodium lamp color temperature between 2000 k to 2500 k, and the color temperature of white light-emitting diodes (oleds) in more than 3000 k, this is also why people think it is too dazzling, too bright. Many people complain about white leds is too light, lit up the whole street, influenced their sleep. Others point out that leds will light pollution and retinal damage. Although many residents complain, led street lamp manufacturers still believe that the benefits of light emitting diode is far more than these shortcomings. In the current situation, change of installed led street lamp is a waste of manpower, material and financial resources. And it brings convenience and bring value compared to the problem of led lighting products is still a social need and accept, as long as they are reasonable and not excessive use, such as reducing the use of children, as far as possible choose yellow light-emitting diodes (leds), pay attention to protecting leds shell and avoid exposure to light. Led lamp manufacturers also suggest that you should choose your favorite sense of light. Is white light, color temperature 5800 k - 6300 k, Gao Liuming, applicable range, strong color rendering. Color temperature of 4000 K - 5000 K neutral light. Household is mainly in the color of light, create a warm atmosphere. Any development and application of science and technology is a double-edged sword. People should learn to accept it, smarter, and play the advantages of it, limit or control its adverse applications. This is a scientific attitude towards life.
