Cause Bo said in the previous article, "From the consumer perspective LED streetlight standards" have introduced the current domestic LED lamp industry standard than the chaos of the reason, in fact, specifically LED lights criteria should be divided into two parts: Performance indicators and health indicators. But the standard here, a great number of domestic small business or not compliance, performance indicators in line with a number of large companies, but health indicators still blank, many companies said health standards are European and American standards. The development of standards is to have a scientific basis, based on extensive scientific and objective data on the basis of the experimental. Because of different races on color temperature, color rendering index, illumination and other indicators of visual health requirements are different. And different regions, when the sun dipped, energy is the extent (clouds, air) is not the same absorption, light intensity is different, so the color temperature is different, this is the health indicators of people of different races in different regions, LED lights should be different . This is just one aspect of the standard, LED lights use different production sites of Zhengzhou, where pole is good, but also have a certain standard, the above said is the overall standard. For example pedestrian lighting, area lighting and street lighting are standard will be different. For example, that people walking on the road of LED lights, LED lights illuminate pedestrians pole, requiring optical perforation and more gentle angle changes, the light emitted to gentle high visual comfort. As for the residential quarters of the LED lights, the color temperature is lower than 4000 K LED lamp is more suitable, but in fact the most widely used is 3000 K LED lights, lamps and illumination of the lamp lumen output is lower for the community, not only outdoor, indoor lighting is also appropriate standards. Bo tells cause solar lights can illuminate different areas, solar street light uses the sun. It includes a solar panel, battery charger, rechargeable battery Zhengzhou pole lookin home purchase, and the LED light bulb composition. Depending on the requirements and model selection, it can be a small independent unit, or it can be a large system. In the latter case, the machine has a large solar panel, a large battery. Battery-powered lamps used in many work at night. Kaiyuan solar street below the components of the system manufacturers to introduce solar lights: solar energy is an inexhaustible, clean energy, and if oil to calculate solar radiation to the Earth approximately equal to 2.5 millions of barrels per day of oil . Therefore, solar energy is a huge source of energy. When it comes to the use of solar energy, mainly by the two forms, there are active and passive. Wherein the active use of mainly using photoelectric conversion, the passive use of that light and heat conversion. Solar street light with vast solar energy resources for the good of what pole quality energy Zhengzhou, where the sun can recharge the battery plates, night reconverted to electricity to provide energy. Solar street light how complex and expensive pipeline laying is not required, compared to traditional lights safer, more convenient and more energy efficient. Typically solar street lighting system is composed of multi-chip or single-chip panels, controlled intelligent light control or charge controller and solar street light control box, low pressure sodium lamp and rectifiers, batteries and pole components. Light efficiency of solar panels is good, wind. Battery box beautiful and practical, usually made of stainless steel. Place the battery and control box controller. Under normal circumstances, the solar system using the valve control sealed lead-acid battery, which is also known as "maintenance-free battery," is help reduce maintenance costs. The charging and discharging of intelligent control also control the cost of solar lights, to achieve a high price. Which Zhengzhou pole good quality, great cause (certified), pole provided by the Henan cause Bo Lighting Equipment Limited. 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.
