Abstract

An illumination device includes an elongate rod-shaped lamp having at least one light emitting diode, an electronic module coupled to a power supply device, a magnetic reed switch coupled with the power supply and a magnetic member, the illumination device being configured such that the lamp is turned ON or OFF in response to the magnetic reed switch and the magnetic member approaching or moving away from one another. The illumination device is installed in a drawer of a cabinet to automatically emit light whenever the drawer is opened.

Claims

1. An illumination device comprising:

a cabinet with at least one drawer, the drawer comprising a front panel, a rear panel, two lateral side panels;

a magnetic reed module, with an elongated tubular body, set in the backend of the drawer, combined with the drawer rear panel, comprising;

a magnetic reed switch, installed on the drawer; and

a magnetic member, installed in the cabinet and at a corresponding position of the magnetic reed switch;

a lamp, comprising at least one light emitting diode and an electronic module coupled to a power supply device to supply electric power to the light emitting diode, and the power supply device being coupled to the magnetic reed module and used to control turning ON/OFF the power supply device, so as to control the light emitting diode to emit light; and

a connecting device, with one end connected with the lamp, the other end combined with the drawer front panel.

2. The illumination device as recited in claim 1, wherein the magnetic reed module further comprises a containing space for containing the power supply device.

3. The illumination device as recited in claim 1, wherein the power supply device is a battery.

4. The illumination device as recited in claim 1, further comprising a tube for installing the electronic module.

5. The illumination device as recited in claim 4, wherein the tube is comprised of an illumination tube and a back tube, and the illumination tube is transparent, and the illumination tube is corresponsive to the light emitting diode.

6. The illumination device as recited in claim 4, wherein the electronic module comprises at least one press pillar disposed at the backside of the electronic module for abutting and securing the tube.

7. The illumination device as recited in claim 4, wherein the illumination device is installed on a lateral edge of the drawer and used as a side rod of a drawer.
