Analysis of the Development Status of Solar Lighting Lamps and Comparison of Advantages

  • 2021-09-07

        Solar lights are converted into electricity by solar panels. During the daytime, even on cloudy days, solar panels can collect and store the energy needed. As a kind of inexhaustible safe and environmentally friendly new energy, solar energy has received more and more attention.

        The use of solar photovoltaic power generation is an irreversible trend in energy utilization. China has become the world’s second largest electricity consumer market after the United States, and its demand growth rate is the highest in the world. However, the shortage of petroleum energy and the urgent need of coal resources have made the existing power generation methods far unable to meet the demand for electricity consumption. The promotion of solar power generation is quite urgent and the market potential is huge. With regard to the market, and to accelerate development, the solar energy industry is bound to have a lot to do.

        Solar lighting products emerge with the popularization of solar water heaters. Here we compare the effects of solar lights and mains lights.


Comparison of Solar Lights and Mains Lights

1. The installation of mains lighting fixtures is complicated

        There are complicated operating procedures in the mains lighting project. First of all, cables must be laid, and a large number of basic works such as excavation of cable trenches, laying of concealed pipes, threading in the pipes, and backfilling must be carried out. Then carry out a long-term installation and debugging, if any of the lines has a problem, a large area of rework is required. In addition, the terrain and lines are complex, and the labor and auxiliary materials are costly.

        While the solar lighting is easy to install: when solar lighting is installed, there is no need to lay complicated lines, just make a cement base and fix it with stainless steel screws.


2. High electricity bills for mains lighting

        There are fixed and high electricity costs in the work of mains lighting fixtures, and it is necessary to maintain or replace the lines and other configurations for a long time, and the maintenance cost is increasing year by year.

        While the solar lighting lamps are free of electricity charges: solar lights are a one-time investment, without any maintenance costs, the investment cost can be recovered in three years, and long-term benefits.


3. Mains lighting has potential safety hazards

        Mains lighting lamps and lanterns bring many safety hazards due to the construction quality, the transformation of landscape engineering, the aging of materials, the abnormal power supply, and the conflict between water and electricity pipelines.

        However, solar lighting has no safety hazards: solar lamps are ultra-low voltage products, which are safe and reliable in operation.


Other Advantages of Solar Lighting Lamps

        Green and environmental protection, can add new selling points to the development and promotion of the noble ecological community; it can continuously reduce the cost of property management and reduce the cost of the public share of the owners. In summary, the inherent characteristics of solar lighting, such as no hidden dangers, energy saving and no consumption, green environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages for real estate sales and municipal engineering construction.

Application of Solar Lights

        The solar light can be widely used in the decoration of grassland, square, park and other occasions, and belongs to the technical field of lamps and lanterns. The lampshade is mainly used to connect the bottom bracket, the battery panel is placed on the battery box and built in the lampshade, the battery box is installed on the bottom bracket, the light-emitting diodes are installed on the battery panel, and the solar panel uses wires to connect the rechargeable battery and the control circuit. The utility model is integrated, simple, compact and reasonable in structure; no external power cord, easy to use and install, and beautiful in appearance; due to the use of light-emitting diodes in the bottom bracket, the entire lamp body is illuminated after light is emitted, and the light perception effect is better; All electrical components are built-in, which has good practicability.

        In practice, of course, solar outdoor lighting lamps will be more complicated. In addition to large-capacity batteries and solar panels, the system also includes advanced dedicated monitors. When the lighting is stopped, the solar-powered battery starts to charge, and then when it is fully charged, it gets more power. The key is that solar outdoor lighting and solar photovoltaic houses are equipped with solar panels, all with a dedicated microprocessor control system and batteries. It is connected to a specially designed load lamp equipped with super reflectivity and high energy ballast. It has the advantages of high brightness, easy installation, reliable work, no cables, no consumption of conventional energy, and long service life. Using high-brightness LED light-emitting diode design, no manual operation is required, the lamps will automatically light up in dark, and automatically go out at dawn. The products have strong sense of fashion, bright texture, fineness, and modernity. They are mainly used in the lighting decoration of residential green belts, industrial park green belts, tourist scenic spots, parks, courtyards, square green spaces and other places.


Classification of Solar Lighting Lamps

        (1) Compared with ordinary LED lights, solar home lights have built-in lithium batteries or lead-acid batteries and are charged by one or more solar panels. The general charging time is about 8 hours, and the use time is as long as 8-24 hours. Generally with charging or remote control function, the appearance varies according to user needs.

        (2) The role of solar signal lights for navigation, aviation, and land traffic lights is very important. In many places, power grids cannot provide power. Solar signal lights can solve the power supply problem. The light source is mainly LED with small particles and directional light. Achieved good economic and social benefits.

        (3) The power of the solar lawn light source is 0.1~1W. Generally, small-particle light-emitting diodes (LED) are used as the main light source. The power of the solar panel is 0.5~3W, and two batteries such as 1.2V nickel battery can be used.

        (4) Solar landscape lights are used in squares, parks, green spaces and other places, using various shapes of low-power LED point light sources, line light sources, and cold cathode modeling lights to beautify the environment. Solar landscape lights can get better landscape lighting effects without destroying the green space.

        (5) The solar sign lamp is used for the illumination of night guide indication, house plate and intersection sign. The requirement for the luminous flux of the light source is not high, the configuration requirement of the system is low, and the usage is large. The light source of the sign lamp can generally be a low-power LED or cold cathode lamp.

        (6) Solar street lights are used in village roads and country roads, and are currently one of the main applications of solar photovoltaic lighting devices. The light sources used are low-power high-pressure gas discharge (HID) lamps, fluorescent lamps, low-pressure sodium lamps, and high-power LEDs. Due to its overall power limitation, there are not many cases applied to urban arterial roads. With the complement of municipal lines, solar photovoltaic lighting street lights will be more and more applied on the main road.

        (7) Solar insecticidal lights are used in orchards, plantations, parks, lawns and other places. Generally, fluorescent lamps with a specific spectrum are used, and the more advanced use of LED violet lamps, through its specific spectrum radiation to trap and kill pests.

        (8) The solar flashlight uses LED as the light source, which can be used in field activities or emergency situations.

        Solar courtyard lights are used in the lighting and decoration of urban roads, commercial and residential communities, parks, tourist attractions, squares, etc. It is also possible to change the above-mentioned mains lighting system into a solar lighting system according to user needs.
