A solar lamp is an electric light that is converted from solar panels into electricity. During the day, even on cloudy days, the solar panels can collect and store solar energy. As a kind of safe and environment-friendly new electric lamp, solar lamp has been paid more and more attention.
First let's understand the system structure of solar lamp. The solar lamp consists of solar cell module, part of LED lamps, control box (the control box contains charger, controller, battery) and light pole. Solar panel light efficiency reaches 127Wp/m2, high efficiency, very favorable for 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 and arranged in a lattice with a certain spacing as the plane light source. The control box is made of stainless steel, beautiful and durable. Maintenance-free lead-acid battery is placed in the control box and a solar street lamp special charging controller is developed by adopting the patented technology of slow pulse rapid charging and discharging. The system USES valve-controlled sealed lead-acid battery, which is also known as "maintenance-free battery" due to its low maintenance, which is conducive to reducing the maintenance cost of the system. In the design, the charge-discharge controller takes into account the complete functions (including light control, time control, over-charge protection, over-discharge protection and reverse connection protection, etc.) and cost control, so as to achieve a high cost performance.
Next, we will talk about the principle of technology. Solar lamp working principle is simple, using the principle of photovoltaic effect made of solar cells. During the day, the solar panel receives solar radiation energy and converts it into electrical energy output, which is stored in the battery after charging and discharging controller. At night, when the illumination gradually decreases to about 101ux, the solar panel open circuit voltage is About 4.5V, the charge and discharge controller detected this voltage value after the action, the battery on the lamp discharge. After the battery discharged 8.5h, charge and discharge control action, the battery discharge. The main function of charge and discharge controller is to protect battery.
Let's look at its advantages. Solar energy generally refers to the radiation energy of sunlight, which is generally used for power generation in modern times. Since the formation of the earth, living organisms have mainly survived by the heat and light provided by the sun. Since ancient times, humans have also known how to use sunlight to dry things and as a way of preserving food, such as salt making and salted fish. However, with the reduction of fossil fuels, solar energy is intentionally further developed. There are two ways to utilize solar energy: passive utilization (photothermal conversion) and photoelectric conversion. Solar power generation is a new renewable energy source. In a broad sense, solar energy is the source of many energy on the earth, such as wind energy, chemical energy, water potential energy and so on.
With the increasing scarcity of the earth's resources and the increasing cost of investment in basic energy, various security and pollution risks can be described as ubiquitous. In this way, solar lighting products emerge with the popularity of solar water heaters. Here we make a practical comparison between the effects of solar lamps and the use of municipal electric lamps.
Contrast one: The installation of municipal electric lighting lamps is complicated. There are complicated working procedures in municipal electric lighting lighting projects. First, cable should be laid. Here, a large number of basic projects, such as cable trench excavation, buried pipe laying, pipeline crossing and backfilling, should be carried out. Then long-term installation and debugging, if any line has problems, large areas of rework. Moreover, the terrain and line requirements are complex, and the cost of manual and auxiliary materials is high. Solar lighting installation is simple: Solar lighting installation, do not need to lay complex lines, as long as a cement base, and then fixed with stainless steel screw.
Contrast two: City electric lighting has potential safety hazards: because of the construction quality, landscape lighting transformation, material aging, abnormal power supply, water and gas pipeline conflict and so on, city electric lighting has brought many potential safety hazards. Solar lighting has no potential safety hazards: Solar lamps are ultra-low voltage products, safe and reliable operation.
Other advantages of solar lighting: green environmental protection, can add new selling points for the development and promotion of noble ecological community; sustainable reduction of property management costs, reduce the cost of public share of owners. In conclusion, the inherent characteristics of solar lighting, such as safety, energy saving, no consumption, green environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages to the sales of buildings and the construction of municipal engineering.
Finally, let's talk about its performance. Solar lamp can be widely used in grass, square, park and other occasions decoration, it belongs to the technical field of lamps. The lamp shade is mainly used to connect the bottom bracket, the solar panel is placed on the battery box inside the lamp shade, the battery box is installed on the bottom bracket, the led is installed on the solar panel, the solar panel USES a wire connection can be charged battery and control circuit. The structure of the utility model is integrated, simple, compact and reasonable. No external power cord, easy to use and install, beautiful appearance. Because the light emitting diode is placed in the bottom bracket, the whole lamp body is illuminated after the light emitting and the light feeling effect is better. All electrical components are built-in with good practicability. Including snake lamp, plate lamp, solar energy neon lamp, massage lamp and so on.
Of course, In practice, solar outdoor lighting is a little more complicated. In addition to large capacity batteries and solar panels, the system includes advanced dedicated monitors. When the lights go off, the solar cells start charging and when they are recharged, they get more power. The key is outdoor solar lighting, solar photovoltaic house solar panels, have a dedicated microprocessor control system and batteries. It is connected to a specially designed load lamp equipped with a super reflectivity and high energy ballast. It has the advantages of high brightness, easy installation, reliable operation, no cable laying, no consumption of conventional energy and long service life. High brightness LED light emitting diode design, no manual operation, automatic lighting in dark, automatic extinguishing in daylight. The products have strong fashion sense, bright texture, fine, modern sense, mainly used in residential green belt, industrial park green belt, tourist attractions, parks, courtyards, square green space and other places of lighting decoration.
