With the promotion of solar street lamp products by the government for many years and the increasing spread of new urban construction, solar street lamps are installed in more and more ways, rural lanes, scenic spots, individual homes, factories and other places.
LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy. It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation.
Early solar street lamps use lead-acid batteries, which have reached the end of their life after seven or eight years of use. At the beginning of the lithium battery has more advantages than lead-acid battery: small size, large capacity, high discharge depth, the use of life factory, many users need to replace the lithium battery, so how to replace the lithium battery solar street lamp lead-acid battery?
The following is a detailed description of the street lamp lithium battery replacement device method:
In the first case, if you want to negotiate with lithium battery solar street lamps, the manufacturer will be responsible for after-sale, so customers do not need to worry too much. The quality of the equipment is guaranteed by the skilled personnel of the manufacturer, and the fault maintenance is convenient in the later stage.
The second case is a customer has the solar street light, need to change into the lithium battery of lead-acid batteries, the company may specifically sends skills man the door device on light pole of lithium battery, take water proof connector may be directly connect with solar panels, the lithium battery voltage maintenance, change the lithium battery need to change the lithium battery at the same time special control device.
The controller working voltage is divided into 12V system or 24V system, the exchange process should be careful. After connecting the lithium battery with the controller, the solar photovoltaic modules charge the lithium battery during the day, in some cases 4-5 hours can be full of electricity, at night when the solar photovoltaic module voltage is lower than 3.7V, the lithium electric controller holds the lithium battery to discharge the light source.
Solar street lamp lithium battery installation method is relatively simple, solar street lamp manufacturers will be responsible for the installation. It is advocated that customers who buy lithium battery solar street lamps do not install their own devices, but need professional manufacturers to install them, so that street lamps manufacturers are not responsible for after-sales service after failure, resulting in unnecessary economic loss.
