Description

Technical Field

[0001] The utility model relates to the field of solar lamps, in particular to a solar lamp with low power consumption and high brightness. Background Art

[0002] The working principle of solar lamps is to convert solar energy into electrical energy to achieve lighting. The top is a solar panel, also known as a photovoltaic module. It uses solar cell modules to generate electricity, batteries to store electricity, and controllers to control the charging and discharging of batteries to work. It does not require laying cables, does not require AC power supply, and does not generate electricity bills. In the past, silicon was used as a solar cell material, but China's ability to produce silicon wafers is still too low, and most materials rely on imports, resulting in too high costs for solar cells. In order to promote solar power generation on a large scale, scientists must reduce the cost of solar cell materials, or find cheaper solar cell materials.

[0003] When optimizing existing solar lamps based on low power consumption and high brightness, most of them are reflected in the aspect of automatic cleaning. For example, the Chinese utility model patent with patent number CN106764885B discloses "An easy-to-clean solar lamp", which includes a lamp post and a lamp body arranged on the lamp post, the lamp body includes a light-emitting mechanism and a heat dissipation mechanism, the heat dissipation mechanism includes a solar cell heat dissipation plate, an LED lamp heat dissipation plate and a water storage vertical pipe, the solar cell heat dissipation plate is fixed on the top of the water storage vertical pipe, the LED lamp heat dissipation plate is located at the bottom of the water storage vertical pipe, the LED lamp heat dissipation plate is provided with a water collecting groove, the water collecting groove is connected to a guide pipe and connected to the water storage vertical pipe through the guide pipe, wherein a torsion spring is connected between the lamp body and the lamp post, and a counterweight block is also connected to the lamp body, the water storage vertical pipe has a water storage part and a deflection part, the deflection part is located above the water storage part and is connected to the water storage part, when the water storage part stores water, the center of gravity of the lamp body remains stable, and when the deflection part stores water, the center of gravity of the lamp body is deflected.

[0004] Although the above-mentioned low-power and high-brightness solar lights have certain advantages in automatic cleaning, they still have certain disadvantages:

[0005] like Figure 6As shown, after the water fills the water storage part, it will gradually flow into the deflection part. The rainwater injected into the deflection part will gradually shift the center of gravity of the lamp body, and the ball in the amplifier tube will roll to one side, eventually causing the lamp body to tilt. The accumulated water in the water storage vertical pipe will flow out through the guide tube again, and the dust accumulated in the solar cell heat sink and the water storage vertical pipe will flow out with the rainwater, thereby cleaning the lamp body. However, it is difficult to protect the above-mentioned solar lamp based on low power consumption and high brightness when not in use, resulting in the solar lamp being easily damaged by external impact when not in use. In addition, it is difficult to collect mosquitoes, cigarette ashes and cigarette butts based on low power consumption and high brightness, resulting in the environmental sanitation around the solar lamp being easily damaged.
