in the photovoltaic technology and LED lighting efficiency under the situation of rapid development, solar street light and solar LED street lamp is popularized and applied in the urban and rural areas, but also exposed some shortcomings and the insufficiency of its existence, especially in the main city road on the application of the illumination brightness and continuous rainy days under the condition of reliability and maintenance of at ordinary times is not satisfactory, the reason is mainly the solar cell conversion efficiency is only about 17%, and ask for a higher power of road lighting solar cells, and related equipment quality, the life also can not meet the relevant requirements, are the causes of unsatisfactory, so its existence, the temporary difficulties, no problem, before installing solar LED street light to moderate and comfortable. 1, adjust measures to local conditions to install solar LED street light. First of all, the sun or poor area should not be installed, high-rise buildings with shortages caused by sunshine city installed as far as possible or not; Second, solar LED street lamp power provided by the current lack of expressway, primary and secondary trunk road and yingbin road illumination requirements, recommend city if installation, is suitable for installation in the yard, parks, green space and landscape, the local rainy night personnel scarce, even no one. Dim light or no lights no greater impact. If install on the road in urban NaDao, recommended to the method of grid complementary lighting, using this method only needs to consider a year sunshine needs the longest, and the night lighting shortest period of electricity demand, the rest can be added by the mains, the largest use of the solar cell efficiency, can use the minimum battery capacity, system costs the least and the solar system has reached the highest reliability can be particularly beneficial to the city was equipped with a lighting cable on the road of solar LED street lamp, for street lamp adopt double circuit power supply of the city better. Adopting solar energy and grid complementary to do a good job related to consider different road lighting to maintain requirements, the choice of the access of the grid points, etc. Outside the city suburbs, rural and island, the scenic spot, the top of the mountain power populated areas or in disaster relief emergency lighting can be appropriately installing solar LED street lamp, can solve the problem of lighting for. 2, moderately install solar LED street light. Solar energy and LED is a new technology, new energy, new light source, is destined to occupy the important position in the future, but there is still in the stage of development, luminous efficiency is low, Currently under high pressure sodium lamp 140 lm/W) Inconsistent, large droop, light color, color temperature deviation, the secondary light distribution processing level is not high, driving power supply design is not perfect, the life is far lower than the LED their own life, the solar cell conversion efficiency is low, short service life of the battery and synchronous control difficult, and many other problems to be solved. We should be objective and rational view on the development of the solar LED lighting, growing, and its future prospects, take the attitude of enthusiasm, support and promote its development, and improve and improve, in the application of solar LED street lamp although shortcomings at present stage, but still has its unique advantages, such as solar LED lighting in certain occasions ( Island, scenic spot, the top of the hill, a remote place, etc. ) In the application of the landscape lighting ( Courtyard lamp, lawn lamp, etc. ) May promote solar system aspects as well as the regional network in centralized mining power supply applications ( Wuxi has set up a file in the test run) And so on, is still obvious advantages, demonstration application also has positive significance. But should not blindly, disorder of promotion. Growth needs a process, the LED street lamp, if not properly treated, LED lighting, now talk about large-scale applications will waste may appear too much investment, investment, leave too much hidden trouble for the future.
