1、How to make a battery-powered advertising light box
Is the light box you made 220V? If so, you must buy an inverter and a battery. The battery needs to be charged every day when it is used up. If this is the case, the inverter cannot be left there for a long time, for fear of water getting wet, the best way is to use it directly. The 12V DC light bulb is directly powered by the battery, so it only needs to be charged.
Photovoltaic panel is a device that can convert solar energy into electrical energy. Common sizes include: 1000x1000mm, 1000x1200mm, 400x1000mm, etc. Different sizes of photovoltaic panels are suitable for different scenarios, and in the 400x1000 size, it is very important to choose the appropriate batteries and lamps.
Battery Selection
In 400x1000 photovoltaic panels, there are three types of batteries commonly used: nickel metal hydride batteries, lithium batteries and lead-acid batteries.
1. Nickel-metal hydride battery
Nickel-metal hydride battery has a high specific energy, can be recharged many times, and has lower storage environment requirements, but the price is relatively high. It has a long service life and is suitable for use in some relatively high-end solar lighting products, such as street lights, advertising light boxes, lawn lights, etc.
2. Lithium battery
Lithium battery has high energy density, no memory effect, and low self-discharge rate. It is suitable for use in high and extreme environments, but the price is higher. Its lifespan is short, generally 2/3~3/4 of nickel-metal hydride batteries. However, due to its small size, light weight and large capacity, it has been widely used in some solar lighting equipment that needs to be lightweight and easy to carry, such as Outdoor solar power bank, flashlight, etc.
3. Lead-acid batteries
Lead-acid batteries are cheap and have large capacity, but they are heavy, require high storage environment, have high self-discharge rate, poor sealing, etc. shortcoming. Due to its low price, it is suitable for use in some low-end solar lighting products, such as solar home lights, solar garden lights, etc.
Selection of lamps
When choosing solar lamps, you need to choose different lamps according to different scenarios, which can be roughly divided into street lamps, lawn lamps and solar household lamps.
1. Street light
Street light is a widely used solar lighting equipment. It generally requires the use of high-brightness lamp heads, coupled with enough photovoltaic panels and battery packs, to be able to Provide adequate lighting at night. In the 400x1000 photovoltaic panel, it is recommended to use high-end batteries such as nickel metal hydride batteries and lithium batteries, coupled with high-brightness LED lamp holders, as well as equipment including charge controllers and inverters.
2. Lawn lamp
Lawn lamp is a kind of solar lighting equipment widely used in outdoor landscape lighting. It generally uses low-brightness LED lamp holders to illuminate roadside lawns and lawns at night. Gardens, etc. provide adequate lighting effects. Its photovoltaic panels, battery packs and other additional equipment are relatively simple, and you can choose cheaper lead-acid batteries and solar home lights.
3. Solar home lights
Solar home lights are a convenient and easy-to-use solar lighting equipment, generally used to provide light sources in outdoor open-air environments. The photovoltaic panels are not large in size, so you can use relatively cheap lead-acid batteries and match them with low-power LED lamp holders. In home use, it is generally necessary to consider
