Abstract

A solar lamp may include a bottom plate, a lamp post, and a lighting complex. In one embodiment, the lamp post is fixed to the bottom plate and has three segments. The three segments are retractable thereby allowing the height of the lamp post to be adjusted. The lighting complex is installed at the top end of the lamp post and comprises a housing and a solar panel which is placed onto the top side of the housing. The housing may include a frame and with glass panels installed, and enclose a LED lamp, a rechargeable battery, and required wirings. The present invention is advantageous because the solar lamp can be easily and quickly installed or uninstalled, and the height of the lamp post can be easily and conveniently adjusted.

Claims

1. A solar lamp comprising a bottom plate;

a lamp post having a plurality of segments that are telescopically connected; and

a lighting complex having a housing and a solar panel, wherein the height of the solar lamp is adjustable by controlling the number of segments of the lamp post.

2. The solar lamp of claim 1, wherein the bottom plate is a square shaped metal plate with four connecting holes each located at one of the four sides of the bottom plate, and a screw bolt will be inserted into corresponding connecting holes to secure the lamp on the ground.

3. The solar lamp of claim 1, wherein the lamp post has a first segment, a second segment, and a third segment;

the size of the first segment is greater than the second segment, and the size of the second segment is greater than the third segment; and

the first segment is fastened on the bottom plate.

4. The solar lamp of claim 3, wherein the first segment and the second segment are hollow, having a first receiving space and a second receiving space respectively;

the first receiving space is configured to receive the second segment while the second receiving space is configured to receive the third segment.

5. The solar lamp of claim 4, wherein the first segment and second segment are connected by a first connector, while the second segment and the third segment are connected by a second connector.

6. The solar lamp of claim 5, wherein the first connector has a first inner securing unit to secure the second segment to prevent undesirable falling into the first receiving space, while the second connector has a second inner securing unit to secure the third segment to prevent undesirable falling into the second receiving space.

7. The solar lamp of claim 6, wherein a second button is located outside the second segment is used to unlock the second inner securing unit of the second connector, so the third segment is received in the second receiving space to lower the height of the solar lamp;

and a first button is located outside the first segment to unlock the first inner securing unit of the first connector, so the second segment with the third segment therein is received in the first receiving space to further lower the height of the solar lamp.

8. The solar lamp of claim 7, wherein by pressing the first button, the second segment is pulled out from the first receiving space until the first inner securing unit restricts the movement of the second segment, while by pressing the second button, the third segment is pull out from the second receiving space until the second inner securing unit restricts the movement of the third segment to restore the height of the solar lamp.

9. The solar lamp of claim 1, wherein the lighting complex is disposed at a top portion of the third segment of the lamp post, and the lighting complex comprises a housing and a solar panel placed on the top of the housing.

10. The solar lamp of claim 9, wherein the housing includes an LED lamp, a rechargeable battery, and related wiring devices to connect the LED lamp to the battery and to connect the battery to the solar panel.

11. The solar lamp of claim 10, wherein the solar panel is disposed on top of the housing and facing upward for sun light collection;

the sun light collected by the solar panel is converted to electrical energy and stored in the rechargeable battery, and when the user turns on the LED lamp, the LED lamp is powered by the rechargeable battery.

12. The solar lamp of claim 1, wherein the solar panel is disposed underneath the housing.
