Solar light emitting diode (LED) garden lamp

Abstract

The invention provides a solar light emitting diode (LED) garden lamp. The solar LED garden lamp comprises a lamp cap, a lamp rack and a storage battery which is arranged in the lamp rack, the upper end of the lamp rack is connected with the lamp cap through a rotating connecting part, and a solar cell panel is fixedly mounted at the lower end of the rotating connecting part. The solar LED garden lamp is characterized in that an LED light source module is arranged in the lamp cap, the solar cell panel comprises an upper layer insulation substrate and a lower layer insulation substrate, a transparent electric conduction layer and a thin film cell panel are disposed between the upper layer insulation substrate and the lower layer insulation substrate, a back electrode layer is mounted between the thin film cell panel and the lower layer insulation substrate, the LED light source module comprises an aluminum substrate and LEDs, a plurality of bowl-shaped grooves are formed in the aluminum substrate, the LEDs comprise chips and fluorescent powder, the chips are fixed on aluminum plates at bottom surfaces of the bowl-shaped grooves, the fluorescent powder is arranged on the chips, and copper foil circuit boards are connected with the chips through gold lines. The solar LED garden lamp has the advantages that the solar energy utilization ratio is high, the service life is long, the luminous efficiency is high, and the like.

Description

technical field [0001] The invention relates to a solar LED garden light. Background technique [0002] The existing solar LED garden lights have the following deficiencies: first, the solar panel has a low ability to collect solar energy; second, the heat dissipation effect of the LED light source is not good, which affects the service life; third, the epoxy resin in the LED is easily disturbed by ultraviolet rays , After working for a long time, the resin gradually becomes cloudy, which affects the luminous efficiency. Contents of the invention [0003] The object of the present invention is to provide a solar LED garden light with high utilization rate of solar energy, long service life and high luminous efficiency in view of the above situation. The purpose of the present invention can be achieved through the following solutions: a solar LED garden light, including a lamp holder, a lamp holder and a battery arranged inside the lamp holder, the battery is electrically ...
