Abstract

An illuminating device comprises a base dimensioned to fit into the receiving cavity of an article. The base is provided therein with a threaded portion, a battery compartment, a lighting compartment, a first circular surface located between the threaded portion and the battery compartment, and a second circular surface located between the battery compartment and the lighting compartment. A light-emitting body is located in the lighting compartment and is provided with a first pin in contact with a battery set located in the battery compartment, and a second pin extending to locate on the first circular surface. A rotary switch is engaged with the threaded portion of the base and is provided with a conduction piece and an elastic conduction body located between the conduction piece and the battery set. The rotary switch is rotated to cause the conduction piece to remain in contact with the second pin so as to bring about the illuminating effect.

Claims

1. An illuminating device comprising:

a base dimensioned to fit securely into a receiving cell of an article and provided with a bore having a threaded portion, a battery compartment, a lighting compartment, a first circular surface formed between said threaded portion and said battery compartment, and a second circular surface formed between said battery compartment and said lighting compartment;

a conduction member located in said battery compartment of said base;

a light-emitting body located in said lighting compartment of said base and provided with a first pin and a second pin;

a battery set located in said battery compartment of said base, said first pin of said light-emitting body engaged to said battery set; and

a rotary switch having a threaded portion rotatably engaged with said threaded portion of said base, said rotary switch having a seat, extending through a center hole of a conduction piece, and an elastic conduction body fitted over said seat, said elastic conduction body being located between said conduction piece and said battery set, wherein said elastic conduction body permits said conduction piece to make electrical contact with said second pin of said light-emitting body through said conduction member at such time when said rotary switch is rotated;

wherein said conduction member is composed of an outer conduction tube and an inner insulation tube, said outer conduction tube provided at a first end with a through hole and at a second end with a lip extending from a periphery of said second end to engage said first circular surface, said inner insulation tube being fitted into said outer conduction tube such that said first pin of said light-emitting body extends through said inner insulation tube and that said second pin of said light-emitting body is engaged between said through hole and said outer conduction tube to engage with said battery and said inner insulation tube.

2. The device as defined in claim 1, wherein said light-emitting body is a light-emitting diode (LED).

3. The device as defined in claim 1, wherein said first pin and said second pin of said light-emitting body extend through said through hole of said outer conduction tube of said conduction member.

4. The device as defined in claim 1, wherein said inner insulation tube of said conduction member is provided with a guide hole;

and wherein said first pin of said light-emitting body extends into said battery compartment of said base through said guide hole of said inner insulation tube of said conduction member.

5. The device as defined in claim 1, wherein said light-emitting body and said battery set are provided therebetween an integrated circuit for controlling a glaring effect of said light-emitting body.

6. The device as defined in claim 1, wherein said base and said article are transparent.

7. The device as defined in claim 1, wherein said base and said article are translucent.
