Commercial customized 200w led street light supply for high road

In recent years, solar energy as a clean and environmentally friendly energy source has become familiar to the public, and the concept of energy saving and environmental protection has been deeply rooted in the hearts of the people, more and more people have begun to realize the positive impact of green environmental protection on our lives, the solar lighting industry has gradually gained social recognition and development.Especially solar street lights, one of the main solar lighting, it has ultra-high environmental protection. At the same time, solar streetlights are unmatched by ordinary streetlights in performance. Therefore, solar streetlights are more and more widely used.The working principle of the solar street light system is simple. During the day, the solar panel receives solar radiation energy and converts it into electrical energy which is stored in the battery through the charge and discharge controller, when the illumination gradually decreases at night to reach the set value, the charge and discharge controller automatically detects and sends a braking command, and the battery starts to discharge, so the solar street light can be turned on automatically when the night come.Advantages of solar street lights:1) No need to lay cables, no AC power supply, no electricity bills;2) Photosensitive control;3) Good stability, long life, and high luminous efficiency;4) Easy for installation and maintenance;5) High safety performance, energy saving, and environmental protection, economical and practical.Application:It can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots, and other places.Lighting, beautiful, plays the role of road signs, signs of civilization, solar street light has become an indispensable part of people's lives.When choosing solar street lights, need to consider the road section to be installed. Different road sections and different environments will have different choices.The price of street lamps is different, in addition to the different materials, there are also different brands. Zhongshan ALLTOP Lighting Co., Ltd focuses on the research & development and production of solar lights and solar power systems insists on product development and technological innovation and has become a leading supplier of solar lighting products in China with its professional manufacturing capabilities and customer service system

Nowadays, under the situation that natural resources are less and less, green energy is more and more important, and the relevant products become more and more popular. ALLTOP LIGHTING COMPANY had been aware of this commercial opportunity for years. So we have devoted such solar products over 14 years and have a certain position and reputation in the market.All solar products rely on solar panels, whatever solar lamps, and solar systems. So today, let us make a detailed introduction to solar panels.Solar panels (also called solar cell modules) have multiple solar cells for the assembly of the assembly. A solar cell, also known as a "solar chip" or "photocell", is a photoelectric semiconductor sheet that uses sunlight to generate electricity directly. A single solar cell cannot be used directly as a power source. For power supply, a number of individual solar cells must be connected in parallel and tightly packaged into modules.Electric-Generation PrincipleThe sun shines on the semiconductor P-N junction, forming a new hole-electron pair. Under the action of the electric field of the P-N junction, the hole flows from the p region to the n region, and the electron flows from the n region to the p region. When the circuit is connected, the current is formed. That's how photoelectric effect solar cells' work.Solar power generation There are two types of solar power generation, one is the light-heat-electricity conversion mode, and the other is the direct light-electricity conversion mode.(1) The light-heat-electric conversion method uses the thermal energy generated by solar radiation to generate electricity. Generally, the absorbed thermal energy is converted into the steam of the working medium by the solar collector, and then the steam turbine is driven to generate electricity. The former process is the light-heat conversion process; The latter process is the thermoelectric conversion process(2) The photoelectric effect is used to convert solar radiation energy directly into electric energy. The basic device of photoelectric conversion is the solar cell. The solar cell is a device that directly converts solar light energy into electric energy due to photogeneration volt effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will turn the solar light energy into electric energy and generate current. When many cells are connected in series or in parallel, a square array of solar cells with relatively large output power can be formed.Composition and FunctionAt present, crystalline silicon (including polysilicon and monocrystalline silicon) is the most important photovoltaic materials, its market share is more than 90%, and in the future for a long period of time will still be the mainstream materials of solar cells.Solar panel composition and functions of each part:(1) Toughened glass: Its role is to protect the main body of power generation (such as battery), and its selection of transmittance is required:Light transmittance must be high (generally above 91%); 2. Super white toughening treatment.(2) EVA: Fixed toughened glass used for bonding and power (battery), the merits of the transparent EVA material directly affect the life of the components, exposed to the air in the EVA aging yellow, thus affecting the light transmittance of the component, thus affect the quality of the component's power in addition to the quality of EVA itself, the component manufacturer of laminating process influence is very big, Such as EVA adhesive degree is not up to standard, EVA and toughened glass, the backplane bonding strength is not enough, will cause early aging of EVA, affect the life of components.(3) Battery: The main role is to generate electricity. The mainstream of the power generation market is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages.In crystalline silicon solar cell, the equipment cost is relatively low, but the consumption and cell cost is very high, but the photoelectric conversion efficiency is also high, in the outdoor sunlight is more suitable for power generation.Thin film solar cell, has a relatively high equipment cost, but the consumption and battery cost is very low, but the photoelectric conversion efficiency is more than half of the crystal silicon cell, and the low light effect is very good, in ordinary light and can also generate electricity, such as the solar cell on the calculator.(4) Backplane: Function, sealing, insulation, waterproof. Generally, TPT, TPE, and other materials must be aging resistant, most component manufacturers are 25 years of warranty, and tempered glass and aluminum alloy is generally no problem, the key is with the backplane and silica gel can meet the requirements.(5) Aluminum Alloy: Protective laminate parts, play a certain sealing and supporting role.(6) Junction Box: Protect the whole power generation system, playing the role of the current transfer station, if the component short circuit junction box automatically disconnects the short circuit battery string, preventing burning the whole system in the junction box is the most critical is the selection of diode, according to the type of battery in the component, the corresponding diode is not the same.(7) Silica Gel: Sealing function, used to seal components and aluminum alloy frame, components, and junction box junction some companies use double-sided adhesive strips, and foam to replace silica gel, silica gel is widely used in China, the process is simple, convenient, easy to operate, and the cost is very low.

Solar Street lights are being widely used to light up street, lawns, parks, etc. These solar street lights consume no power from the grid and work solely on the solar power. They also eliminate the need for underground cabling and multiple switching points.Zhongshan ALLTOP is one of Solar Lighting Manufactures ,which is located in Zhongshan City with more than 12 Years Experiences on Solar Street Lights/ Flood Light/Power System etc. The solar energy is absorbed in the daytime and is stored in the battery to power the light in the night. The light is set to be switched on once the input voltage from the solar energy falls below a threshold limit. The light is set to be switched off automatically, once the input voltage from the solar energy raises above a threshold limit.  This makes the light to glow once it becomes dark and light to switch off in the dawn. Types of Solar Street LightsSolar Street Lights are of two types. 1. Traditional Solar Street Light (also called All-in-two Solar Street Light)2. All in One Solar Street Lights            The Type of Solar Street Light Image is called All-in-two Solar Street LightThe above Type is called All-in-one Solar Street Light Components of a Solar Street LightSolar PanelSolar panel is the source of power for the solar street light. It collects the solar energy from the sun and converts it into DC power. The power of the solar panel depends on the luminary capacity and the required autonomy days. Charge ControllerCharge Controllers regulate the charging and discharging of the battery They regulate the incoming voltage to charge the battery and prevents the deep discharge of the battery. In a solar street light, the circuit to switch on and off the luminary is enclosed along with the charge controller. The charge control is either provided as a separate device or enclosed inside the luminary.  BatteryBattery stores the power generated by the solar panel. The type of battery used is C 10 Tubular battery. In some cases SMF batteries are also used as they are maintenance free and economical. The all in one street lights use Lithium Ion batteries.In terms of longer life, C 10 rated tubular batteries are the best. PoleThe all in one street light can be fitted either on a pole or on a wall. In the traditional solar street, the luminary alone can be fitted either in a pole or a wall. The pole is either MS or GI and is anti corrosive. The pole has provisions to mount the solar panels and the battery. The pole has a luminary mounting arm and solar panel mounting arm.          

We all know that street lamps need to work all night to bring light to people who go home late at night, but this kind of long-term use is very power-consuming, so in order to save energy consumption, solar street light now are the trend.Zhongshan Alltop lighting. Street light would like to explain how it works.In general, solar lamp manufacturers provide street lamp control devices with timing, light control, and even rain control functions, which are very convenient to use.Solar street lamp in the daytime under the control of the intelligent controller, the solar panel through the sunlight irradiation, absorption of solar light and converted into electric energy, the solar cell module to charge the battery bank in the daytime, the battery bank to provide power at night.The DC controller can ensure that the battery bank is not damaged due to overcharge or over-discharge. It also has light control, time control, temperature compensation, lightning protection, anti-J protection, and other functions.The solar remote control can avoid the lithium battery will not charge too much and causing damage, and the remote control has multiple functions with timing, luminosity adjustment, lightning protection lamp function, and a good realization of night lighting.The solar street lamp is a more basic and convenient control method with more applications. This controller does not need to adjust the time, will automatically sense the light intensity to control the light on and off, after the installation does not need to adjust the time of light on and off according to the season. The sky automatically goes out and the night automatically lights up. This kind of light control is now widely used in lithium solar street lamps.
