The solar light consists of a solar cell module, a part of LED lamps, a control box (which has a charger, a controller, a battery), and a lamp pole. The light efficiency of the solar panel reaches 127Wp/m2, and the efficiency is high, which is very beneficial to the wind resistance design of the system. In the lamp holder part, 1W white LED and 1W yellow LED are integrated on the printed circuit board with a certain distance between the lattice as the plane light source.
The control box body is made of stainless steel, beautiful and durable; The maintenance-free lead-acid battery is placed in the control box, and the solar street lamp charging controller is successfully developed by using the patented technology of slow pulse fast charge and discharge. The valve-controlled sealed lead-acid battery is used in the system. It is also called a “maintenance-free battery” because of its little maintenance, which is helpful to reduce the maintenance cost of the system. The charge and discharge controller takes into account the complete functions (with light control, time control, overcharge protection, over-discharge protection, reverse protection, etc.) and cost control, to achieve a high performance-to-price ratio.
The working principle of solar light is simple. The solar cell base on the photovoltaic effect receives solar radiation during the day and converts it into electric energy output. It is stored in the battery through the charge and discharge controller. When the illuminance is gradually reduced to about 101ux at night and the open circuit voltage of the solar panel is about 4.5V, the charge and discharge controller detects this voltage, and the battery discharges the lamp holder. After 8.5 hours of battery discharge, the charge and discharge control act, and the battery discharge end. The primary function of the charge and discharge controller is to protect the battery.
The solar lamp can be widely used on lawns, squares, parks, and other occasions for decoration, belonging to the technical field of lights and lanterns. The utility model mainly adopts a lampshade to connect the bottom bracket, the battery board is placed on the battery box and inside the lampshade, the battery box is installed on the bottom rest, the light-emitting diode is installed on the battery board, and the solar panel uses wires to connect the rechargeable battery and the control circuit. The utility model has the advantages of a simple, compact and reasonable structure, no external power line, convenient use and installation, and a beautiful appearance. Due to the use of a light-emitting diode in the lower bracket, the whole lamp body is illuminated after light, and the photographic effect is better; All electrical parts are built in, and fine practicability. Incorporate serpentine lights, panel lights, solar neon lights, massage lights, etc. Other advantages of solar lighting: surrounding protection, can add new selling points for the development and promotion of a noble ecological group, can continuously reduce the cost of property management, and reduce the public share of the cost of owners. To sum up, solar lighting has the inherent characteristics of no hidden dangers, no energy consumption, green environmental protection, easy installation, automatic control, and maintenance free. It will bring distinct advantages to real estate sales and municipal engineering construction.
So how should we choose solar lights?
1. Panel size.
The choice of solar panels should base on the size of the space illuminated by solar lamps and the needs of the individual. Generally, the larger the space, the larger the panel, so that the panel can absorb more sun, and the subsequent power supply is more competent. The common panel sizes are 19 cm x 22 cm, 24 cm x 35 cm, 35 cm x 35 cm, 35 cm x 46 cm and so on. Panel size will also affect its power and conversion rate. In daily life, the choice of a conversion rate of more than 18% is actually enough.
2. Battery size.
The solar lamp works by absorbing the solar heat through the panel and then converting it into electricity to store it in the solar internal battery. Generally speaking, the larger the capacity of the cell, the more electricity it stores, and the longer it can last, so if you want to use the solar lamp for a long time, it is recommended to choose the one with a larger battery capacity.
Its capacity, but also pay attention to the number of internal batteries, generally three to four cells, its battery life will be relatively longer.
3. The number of light bulbs.
The interior of the solar lamp is composed of many little light bulbs. Often the more the number of small light bulbs inside, the brighter the brightness it can emit, and in most cases, the more internal light bulbs, the larger the volume of the solar lamp. So when you choose, you should look at the situation or consult the business to see how big the area your home needs.
4. the material of the lampshade.
There are two kinds of common lampshade materials. One is plastic material, and the other is metal material. Generally speaking, it is recommended that we choose the lampshade of metal material, because the lampshade of metal material is not easy to damage in the case of clear heat of lamps and lanterns. The whole will be more stable, and the service life of such a lampshade will be longer. In addition, we should also pay attention to choosing a lampshade with better light transmittance.
5. Select performance.
When buying solar lamps, you should pay attention to whether this lamp has performance of waterproof and lightning protection. So that it will not burn out or even cause electric shock in some thunderstorm weather, and be sure to install ground wires when connecting solar lamp lines.
Solar lamps will be more democratic in the future than they are now. Not only is it easy to install and safe to use, but also the sun is inexhaustible. We don’t need to worry about it. Our current living environment is still a shortage of oil energy and urgent coal resources, which makes the existing power generation methods far from meeting the demand for electricity consumption. Solar power generation promotion is an emergency, and the market potential is enormous. Aiming at the market and accelerating its development, the solar cell industry must have a bright future.
