Abstract
A power saving lamp includes a base, a cover, a light source and a solar cell. The cover is fixed on the base. The light source is arranged on the base and inside the cover. The solar cell is arranged on the base or the cover and close to the light source. The solar cell can convert the solar power into electric power for further use to realize the use of driving the light source to emit light. The utilization efficiency of the light from the light source can be improved and the electric power can be saved. Besides, when the solar cell is closer to the light source, the photoelectric converting efficiency of the solar cell is higher and the recycle of the light can be realized. The utilization efficiency of the light from the light source can be further improved and the electric power can be saved.
