Bo tells great cause of China's solar photovoltaic industry has only just begun, it is a never-ending industry. Below small to tell you about the advantages and disadvantages of solar energy. The advantages of solar energy (1) common: the sun shine on the earth, there is no geographical restrictions, whether on land or sea, either mountains or islands, are everywhere, and recent opening direct solar silicon [2] development and use, and without exploitation and transport. (2) sound: development and utilization of solar energy does not pollute the environment, it is one of the most clean energy, environmental pollution is getting worse today, and this is extremely valuable. (3) enormous: Each year the sun to reach the earth's surface radiation equivalent to about 130 trillion tons of coal, which belongs to the largest amount of energy in the world today can be developed. Disadvantage of solar energy (1) Dispersion: the total amount of solar radiation reaching the Earth's surface, despite great, but energy flux density is very low. On average, near the Tropic of Cancer, in the summer the weather is sunny, the irradiance of the largest solar radiation at noon. In the winter, roughly only half cloudy generally only about 1/5 of the energy flux density is so low. (2) Instability: Limited by day and night, season, geographic latitude and altitude and other natural conditions and the effects of sunny, cloudy, clouds, rain and other random factors, therefore, at a certain ground both intermittent solar irradiance , but also it is very unstable, which gives large-scale application of solar energy more difficult. In order to make solar energy a continuous, stable energy, and ultimately become an alternative energy can compete with conventional energy sources, energy storage must be a good solution to the problem, that sunny day solar radiation stored up as much as possible 40W solar street lighting manufacturers to for night or on cloudy days, but there is also one of the solar storage utilization weak link. Bo said the cause of the small series and some of the problems often said LED light on the site, in this article, will be mainly from the good, LED light two issues bad talk, not just from the LED light LED lights, including other LED lighting problems. Lights in people's lives, in the city at night activities, roads, commercial lighting, people on the street certainly more and more attention. Because the light directly affects the health and quality of human beings, in fact, there is not only a man of plants and animals. Let me talk about the good aspects: First, that in medicine 50W solar street lighting manufacturers, talk about LED is a semiconductor light-emitting device, ends with a suitable voltage, into the semiconductor carrier fluid occurs in line with 80W solar street lighting manufacturers, causing photon emission is generated light. Say the practical lights manufacturers, to modern medical cosmetic surgery hospital, Ms. love long acne, will give you a certain degree of LED light irradiation, acts as an anti-inflammatory. The main effect of light stimulation wavelength, the irradiation dose and the way, and the final therapeutic effect, and would need professional doctors to grasp this problem dose and manner. Disadvantages of light: interference or excessive light pollution caused by optical radiation are harmful to human health and the impact on the human environment. You can directly kill insects and plants. Not only is the sun, the light also cause photoaging, that human skin aging, because it causes the secretion of the human brain to remove melatonin in the pineal gland. 50W solar street lighting manufacturers, cause Bo (certified), street by the Henan cause manufacturers to provide lighting Equipment Co., Ltd. Bo. Henan cause Bo Lighting Equipment Co., Ltd. (www.zzdybcdj.com) is Zhengzhou City View light fixtures leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the cause of the leadership with the staff warmly welcome all inquiries negotiations to create the great cause of a better future.
