1 species classification has a variety of solar street lamps, solar street lamps, according to the source of cocoa is divided into the LED solar street lamp, electrodeless lamp, solar street lamp, energy-saving lamp, solar street lamp, etc. , according to the occasion can be divided into ordinary solar street light, high solar street lamp, garden landscape solar street light, solar street lamp, etc. 2, street lamp light lamps light have LED lamp, electrodeless lamp, the ordinary energy-saving lamps, metal halide lamp, etc. , and the street lamp light source, which is really good? Metal halide lamp with ordinary CFLS cost is not high, has long service life, maintenance is convenient, but such a street lamp light source power is relatively high, it is not recommended to choose; Electrodeless lamp also is a kind of energy-saving lamps, theory of life also pretty long, but the cost is high, the maintenance is not easy, this kind of light source is also not recommended choice; Street lamp LED light source is used most frequently in recent years, the light source, high efficiency and energy saving, environmental protection, long service life, convenient maintenance, price is not expensive, and many countries and regions are vigorously promoting LED, LED street lamp light source selection recommendation, LED solar street light road lighting is the preferred. 3 interval of street lamp, solar street lamp spacing interval are street lamps, is by the street lamp, street lamp lighting power on a variety of factors such as height, width of the road. Street lamp spacing is commonly 3 light pole height. 8 - 4 times. Street lamps and lanterns of the longitudinal spacing generally is 30 ~ 50 metres, when power pole or other pole, about 40 ~ 50 metres apart. Will power pole and lighting pole pole, as far as possible to save investment, if the underground cable power supply, spacing should be small, promotes the uniformity of illumination, usually is 30 ~ 40 metres spacing. 4 high solar street light, solar street lamp, Street lamp light pole height) Generally speaking, there are 4 m, 5 m, 6 m, 8 m, 10 m, etc. , street lamp highly specific usage according to the road width, general unilateral cloth lamp, street lamp height and width of the road is consistent, or street lamp height is less than the road width 1 meter. Common LED lamp power light pole height in relation to the general: 30 ~ 60 w street light height 6 meters, 60 ~ 100 w street light height 8 meters, 100 ~ 150 w street light height of 10 meters. are unique secondary optical design 1, LED light source efficiency 100 lm/W, also has the very big development space, and the theoretical value of 250 lm/W. And high pressure sodium lamp luminous efficiency was increased with the increase of power, as a result, the overall smooth effect better than high pressure sodium lamp, solar street lamp 2, has a unique secondary optical design solar street lamps, solar street light to the lighting area, further improve the efficiency of the light, in order to achieve energy-saving purpose; 3 -, solar street light itself characteristics - - - - - - The unidirectional light, no light diffusing, guarantee the light efficiency; 4, solar street light light color is higher than high pressure sodium lamp, high-pressure sodium lamp only around 23 color rendering index, and the solar street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, solar street light can, on average, more than 20% lower than the high-pressure sodium lamp, ( With reference to the British sense lighting standards) ; 5, solar street lamp light failure is small, light failure is less than 3% a year, still meet the requirements of road use illuminance to 10 years, and high pressure sodium light failure is big, has fallen by more than 30% a year or so, as a result, solar street light on the design of the use of power can be lower than the high-pressure sodium lamp; 6, solar street light automatic control and energy saving device, can realize under the condition of meet the requirements of different times lighting the biggest possible to reduce the power, saves the electricity.
