Abstract

A solar energy-operated street-lamp device is disclosed. The solar energy-operated street-lamp device is characterized in that the solar energy-operated device includes a solar energy-operated absorption board, a circuit board and a storage battery that is mounted within a post seat of the lamp-post. The power stored in the storage battery will be delivered to an LED via circuit board to provide illumination. The solar energy absorption board and the transparent protective hood are of arc-shape so that the sunlight can be converged onto the solar energy absorption board and at the same time, dust particles and birds'"'"' excrement or fallen leaves will not be collected on the surface of the hood surface.

Claims

1. A solar energy-operated street-lamp device comprising a solar energy absorption board and a circuit board each located within a lamp seat of a street-lamp;

and a storage battery;

wherein the solar energy absorption board comprises a plurality of solar energy batteries arranged in a row for absorption of solar energy;

the circuit board is a circuit board body having a recharging circuit for recharging the storage battery and an illumination circuit for illuminating LEDs;

energy converted by the solar energy absorption board is stored via the circuit board as electrical energy in the storage battery; and

the storage battery is provided with an electrode connector with external threads and a center wire insertion hole, and a wire is inserted into the insertion hole via a through-hole on a covering cap and a through-hole of a waterproof pad, the covering cap urges the pad to an upper end of the electrode connector so as to secure the wire, preventing current leakage as a result of water leakage;

a center of a top face of a hood surface of a transparent protective hood at a top of the lamp seat has a conic shape and is converged into a conic body;

a light-focused reflective hood is positioned below the lamp seat and has a conic shape, and an inner wall of the reflective hood is provided with a mirror surface and a plurality of LEDs are provided on a top of the reflective hood and are facing the mirror surface; and

a colored diffusion lamp shade located below the reflective hood produces corresponding color when illuminated by the LEDs.

2. The solar energy-operated street-lamp device of claim 1, wherein the hood surface of the protective hood has a multiple-side conic shape.

3. The solar energy-operated street-lamp device of claim 1, wherein the protective hood has undergone a smooth treatment process so that particles, dust, bird feces, or fallen leaves do not collect thereon.

4. The solar energy-operated street-lamp device of claim 1, wherein the transparent protective hood has a pointed conic shape.
