## Abstract

A solar street lamp includes a connecting base configured with a mounting port for mounting the solar street lamp on top of a lamp post. A bottom plate having a rear portion mounted on top of the connecting base includes a lower surface upon which is mounted, in a forward portion of the bottom plate, a plurality of light-emitting modules. A solar panel is supported above the bottom plate and separated from the bottom plate by a wiring gap space. A battery and power supply are mounted below the bottom plate, inside a mounting chamber formed in the connecting base. A rear plug is detachably disposed on a rear edge of the connecting base. Detaching the rear plug provides access for maintenance to the power supply and battery mounted in the mounting chamber and permits the solar panel to be withdrawn from the solar street lamp.

## Claims

### Claim 1

A solar street lamp, comprising:
a solar panel to convert sunlight into electrical energy;
a plurality of light-emitting modules that emit light using the energy converted by the solar panel, the light-emitting modules being mounted on a bottom surface of a bottom plate;
first and second connecting bars each having an upper groove for supporting a side edge of the solar panel and a lower groove for supporting a side edge of the bottom plate, wherein the first and second connecting bars are configured to support the solar panel and the bottom plate a predetermined minimal separation based on a wire gap space used to interconnect components of the solar street lamp, the first and second connecting bars serving to seal sides of the wire gap space;
a front plug disposed at a front end of the bottom plate, for sealing a front of the wire gap space;
a rear plug disposed at a rear end of the bottom plate, for sealing a rear of the wire gap space;
a battery to receive and store the energy converted by the solar panel;
a power supply that provides power from the battery to the light-emitting modules, the battery and power supply being mounted in the solar street lamp below the bottom plate; and
a connecting base for mounting the solar street lamp on top of a mounting pole or post, the connecting base configured to have:
a mounting port comprising an opening on a bottom side of the connecting base, to fit over a top of the mounting pole or post;
an upper surface configured to support a rear portion of the bottom plate; and
a mounting chamber configured to mount the battery and the power supply as being mounted below the bottom plate of the solar street lamp,
wherein the connecting base is further comprised to have an access port for the mounting chamber such that the rear plug configured for sealing a back area of the wire gap space is further configured to seal the access port for the mounting chamber such that removing the rear plug provides an access to the mounting chamber of the connecting base for servicing the battery and the power supply.

### Claim 2 (depends on 1)

The solar street lamp of claim 1, further comprising a control module mounted in the mounting chamber of the connecting base, to automatically control an illumination brightness of the light-emitting modules.

### Claim 3 (depends on 2)

The solar street lamp of claim 2, wherein the control module comprises:
a microwave emitter;
a microwave inductor;
an arithmetic comparator; and
a control circuit which is connected with the light emitting modules.

### Claim 4 (depends on 1)

The solar street lamp of claim 1, wherein the mounting hole at the bottom of the connecting base is configured to be fixedly connected with a top of a lamp post and an included angle between an axis of the mounting hole and a bottom surface of the bottom plate is predetermined to aim the light-emitting elements in a predetermined desired orientation without any adjustment.

### Claim 5

A solar street lamp, comprising:
a solar panel supported above a bottom plate at a predetermined distance based on a wire gap space minimally needed to provide interconnection wiring for components of the solar street lamp, the bottom plate having mounted on a bottom surface of a front portion thereof a plurality of light-emitting modules;
a connecting base upon which the bottom plate is supported in a rear portion of bottom base, the connecting base configured with a mounting chamber inside of which mounting chamber are mounted a battery to store energy converted by the solar panel and a power supply to supply power to the light-emitting modules;
a front plug disposed at a front end of the bottom plate, for sealing a front of the wire gap space; and
a rear plug disposed at a rear end of the bottom plate, for sealing a rear of the wire gap space,
wherein the solar panel is supported above the bottom plate using first and second connecting bars each having an upper groove for supporting a side edge of the solar panel and a lower groove for supporting a side edge of the bottom plate, the first and second connecting bars providing side seals for the wire gap space,
wherein the mounting chamber of the connecting base has an access opening that is covered by the front plug when the front plug is attached, and
wherein, when the front plug is detached, the access opening of the mounting chamber permits access to service the battery and power supply.
