Solar Lawn Lights

The above number for the new installation of the initial illumination value of lighting, so the illumination can not meet the fast road and trunk road. Solar street lights should be used in the trunk road, slip road, the main road with caution. 2, lighting timeLED lights daily working hours should be the same as the general requirements of the work of the street, the design should consider the winter sunshine time is short, its working hours should be able to 12 hours above. As the LED lights affected by the weather larger, in case of continuous rainy days to make LED lights lack of electricity and can not be used. The state is no standard on the LED lights in the low irradiance (continuous rainy days), allowing minimum working hours without making the provisions, is generally based on the lighting manufacturers and local weather conditions, should be low intensity (continuous rainy days) work Situation in the work of 15 to 20 days. In the design should take full account of the capacity of solar panels and batteries. 3, lightning protection groundingLED street lamp operating voltage is generally 12V or 24V, is a safe voltage, do not do electrical protection grounding. But LED street lamp metal pole should do lightning protection grounding resistance is not greater than 10 ohms.

Wuwei Vocational College Graduation Design??Today, the full development and utilization of solar energy is the world 's sustainable development of energy policy decisions, energy conservation has become the theme of social life. Road lighting and people's production and life are closely related, with the accelerated process of urbanization in China, green, efficient, long life LED lights gradually into the people's vision. Compared with the traditional lighting tools, ultra-bright white LED lighting source small size, light weight, good direction and can withstand a variety of harsh conditions, in terms of power consumption, life and environmental aspects of unparalleled superiority, plus On the energy efficiency of solar lamps and easy installation, so where the frequency of alternating current lamps, LED lamps will reach the antenna, the 21st century will be solid luminescent materials as the core, that is, represented by LED as a new light source, green The century of lighting. In the future, with the government's attention and increase investment, solar LED lights will become a century of highly competitive new green light source and set off a new revolution in the field of lighting. Solar LED road lighting does not need to set up transmission lines or trench laying cable, do not have to manage and control, can be installed in the square, parking, golf courses, parks, parks, streets and highways and other places. According to the relevant principles of design and aesthetics, this paper sets out six sets of street lamp design and selects one of the more suitable ones.
