solar consists of internal hydrogen release huge nuclear fusion can, as a result of the radiation energy from the sun. The vast majority of human energy you need to directly or indirectly from the sun. Different solar light life, can choose the light source with low pressure sodium lamp, low-pressure electrodeless lamp, LED lamp, low fluorescent lamp, etc. Using sodium lamp and LED lamp is more now. Sodium lamp is cheap. Life is short. Now LED lights good quality in 50000 hours, 10 hours a day in theory, can be used more than ten years. So choose a good light source in the first place.
solar lamps and lanterns of lamps and lanterns of life than ordinary power is much higher, the life of a, as a major part of the solar lamps and lanterns - - - Solar energy battery components of the service life of 25 years; The average life span for the low pressure sodium lamp 18000 hours; The average life span for the low efficient tricolor energy-saving lamps 6000 hours; The average life span for the LED more than 50000 hours; Special solar battery lifespan is 38 2 - under ah Five years; 38 - 3-150 ah 7 years. According to the local price bureau in accordance with the conventional area 'village street lights maintenance fee one-time charge according to the pure residential construction area 6 yuan / ㎡' regulation, make ordinary higher initial investment solar lamps and lanterns of lamps and lanterns are many initial investment. In short, the characteristics of the comprehensive comparison of solar lamps and lanterns saving investment are quite obvious.
different start in a different way, need different lamp ballast or drive power. This part has much effect on the light source. Especially the LED light source. Now in general use constant current source driver. The stand or fall of constant current source and set parameters is suitable for light source is very important. Basically see: precision of constant current, output efficiency, scope of protection circuit, parameter setting, etc. Choose relatively stable battery performance. And construction should closely, protected from accidental factors such as the water. It will also indirectly affect the service life of street lamps.
