solar street lamps to high-tech energy saving products in modern People's Daily life, however, solar energy while in the course of long-term use final cost generally lower than traditional lights, but due to its cost to install initial capital investment is larger, coupled with repair and maintenance of late as a result of the structure complexity of product cost is higher, so the promotion has been on the point which may be embarrassing. Plus some other smaller r&d and production of solar street lamps factory qualified rate and poor stability of the lamps in the cause of the high failure rate for a lot of people a good impression is to let the promotion of solar street lamps. So how can failure rate of the biggest solar street lamps with utmost to save the cost of late? A solar street lamp, solar street light integral analysis, in a nutshell, is on the basis of the original lighting lamps and lanterns, adopted a new energy supply. But due to the adopted a new energy supply, there will be a lot of form a complete set of components: (1) panels, (2), (3) battery controller. As we all know, the more simple, the less likely the point of failure, and solar energy lamp' Solar energy lamp is by solar panels light into electrical energy. 】 More out of the three key components, the fault point a times more than ordinary lamp, such as between the parts can't compatible with each other, problems came out. Therefore, a combination of solar energy lamp is a unity of science and technology, rather than simple parts assembly body, without mastering certain science and technology, it is hard to produce qualified products. 1. Failure phenomenon ( 1) : light damage is mainly adopts the light source is LED, solar lamp, dc energy saving lamps, dc discharge lamp and energy-saving lamps, etc. (1) the LED is the ideal light source, but to solve the problem of droop; (2) dc discharge lamp, its high light efficiency, very suitable for illumination high places, roads; (3) is currently used more dc energy saving lamps, low cost, low on the main road bar street light and garden light is quite a good light source, take the new rural construction for solar street lamps, a large part of the dc energy saving lamps is adopted. But these are several kinds of light sources ( In addition to the LED is its own reason) As long as in the solar system, its light damage phenomenon is quite a lot. ( 2) : short service life of battery & gt; Battery used in a solar system at present is mainly maintenance-free lead-acid battery' The greatest characteristic of maintenance-free lead-acid batteries, just as its name implies is 'free maintenance. 】 , when in use, in addition to the environment temperature, there are two important indicators: (1) (2) the discharge voltage of charging pressure values. In solar lighting system, overcharge time is not much, and easy to control, and from the annual average 【 。 。 。 】 To calculate, are often under charge, all kinds of brand battery technology index of discharge voltage is essentially 10. 5V( With 12 v battery' Battery is a kind of chemical energy directly into electrical energy device, is designed according to the rechargeable batteries, rechargeable by reversible chemical reactions, usually is refers to the lead-acid battery, it is one of the battery, belongs to the secondary battery. 】 As an example) , but it is put to full fill full set, namely to 0. 1 c discharge rate to measure, and the discharge rate of solar lighting system is in commonly 0. About 025 c, like this small current discharge rate, poor in rizhao, under the condition of insufficient battery charging, such as winter or rainy day in a row, will run out of battery power, appear serious irreversible damage phenomenon, greatly shorten the service life of battery.
