4 Outdoor Solar Lamp for Decorating Garden &Solar Light Bulb With the battery

With the increasing scarcity of earth resources and the increasing investment cost of basic energy,all kinds of potential safety and pollution hazards are everywhere.Solar energy is the most direct, common and clean energy on the earth. As a huge amount of renewable energy, it can be said that it is inexhaustible. The application of outdoor solar energy lamp in environmental protection and energy saving and its gradual formation.

Generally, outdoor solar lamp is composed of solar cell, controller, battery, light source, etc.

1. Solar Panel

Solar panel is the core part of outdoor solar lamp. It can convert the radiant energy of the sun into electric energy and send it to the battery for storage. There are three kinds of solar panels: monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. Polycrystalline silicon solar cells are generally used in areas with sufficient sunshine. Because the production process of polycrystalline silicon solar cells is relatively simple, the price is lower than that of monocrystalline silicon cells. Monocrystalline silicon solar cells are generally used in areas where there are many rainy days and relatively insufficient sunshine, because the efficiency of monocrystalline silicon solar cells is higher than polycrystalline silicon, and the performance parameters are relatively stable. Amorphous silicon solar cells are generally used in special occasions, with the highest price.

2. Controller

It can control the charge and discharge of outdoor solar lamp battery, and also control the opening and closing of the lamp. It uses the light control function to prevent over charging and over discharging of the battery. The most important thing is that it can make the outdoor solar lamp run normally.

3. Battery

The battery performance directly affects the life and performance of outdoor solar lamp. The battery stores the electric energy provided by the solar cell during the day and provides the lighting energy for the light source at night.

4. Light Source

Generally, outdoor solar energy lamp adopts special solar energy saving lamp, low-voltage nano lamp, electrodeless lamp, xenon lamp and   LED light source.

(1) Special solar energy-saving lamp: small power, generally 3-7w, high light efficiency, but short service life, only about 2000 hours, generally suitable for solar lawn lamp and courtyard lamp.

(2) Low voltage sodium has high lighting efficiency (up to 200lm / W), high price, special inverter is required, poor color rendering, and less use.

(3) Electrodeless lamp: low power, high light efficiency, good color rendering. The service life can reach 30000 hours in the municipal power supply, but the service life of the solar lamps is greatly reduced, which is similar to that of the ordinary energy-saving lamps. Moreover, the precise trigger is needed, and the cost is also high. A kind of

(4) Xenon lamp: good light effect, good color rendering, about 3000 hours of service life. The studio needs inverter to heat and astigmatism the light source.

(5) Led: LED semiconductor light source, long life, up to 80000 hours, low working voltage, good color rendering, belongs to cold light source. With high light efficiency, led as the light source of outdoor solar lamp will be a future development direction. At present, there are two kinds of low-power led and high-power LED. Each performance index of high-power LED is better than that of low-power led, but the cost is higher.
