The first thing to understand is that the so-called navigation light you are talking about does not wait. It has no energy of its own and is only a reflector.
The principle is the same as that of your common bicycle rear lights. This is a multi-faceted reflector, no matter it is irradiated with light source at any angle, it can be reflected if you don't. believe it, go to the road at night and observe all the taillights of the bikes. They will “glow” under the illumination of car headlights. In fact, it is simply the omnidirectional reflection of polycrystals.
It's just that the reflective signs on the road now look very different. They use new luminescent film technology and can be attached to any object.
What else can you do with the sun than light paper?
1. Solar water heater: This is relatively common. The tubevacuum absorbs heat from the sun and converts it into thermal energy. Thermal energy is transferred to the water tank to heat the water. Even if it rains continuously, just use the electric heater to heat. A little. You can also use hot water to take a bath at night. If there is no problem, of course you should choose qualified and safe solar power to have such a guarantee and make it convenient, safe and secure. use;
2. Photovoltaic Solar Panels: Many cities have installed solar street lights. Photovoltaic panels absorb sunlight, convert it into electrical energy and store it in the battery. At night, they can produce electricity for lighting. Not only solar street lights, but also solar street lights, lawn lights, table lamps, solar flashlights, solar chargers, etc. are tou made up of photovoltaic panels to absorb solar energy.
3. Solar Heating and Cooling: Used in many projects.
