Abstract

A power switch structure with both light emission and DC power conversion functions is electrically connected to an electric appliance and an AC power supply, and the power switch structure includes a casing, a converting module installed in the casing and electrically connected to the AC power supply for converting AC power into DC power, a control switch electrically connected to the electric appliance, the AC power supply and the converting module for switching a using status of the electric appliance, and switching to an output of the DC power according to the using status of the electric appliance, and a first light source module electrically connected to the control switch and driven by the DC power to emit light.

Claims

1. A power switch structure with both light emission and DC power conversion functions, electrically coupled to an electric appliance and an AC power supply, and comprising:

a casing, having a frame and an installing portion, and the installing portion being disposed at the center of the frame;

a converting module, installed in the casing and electrically coupled to the AC power supply, for converting AC power into DC power;

a control switch, installed at the installing portion, and electrically coupled to the electric appliance, the AC power supply and the converting module, for switching a using status of the electric appliance, and the control switch having a first DC power contact and a second DC power contact provided for switching the DC power to be outputted to the first DC power contact or the second DC power contact according to the using status of the electric appliance; and

a first light source module, having a first LED light source, and being electrically coupled to the first DC power contact and driven by the DC power to emit light.

2. The power switch structure with both light emission and DC power conversion functions as recited in claim 1, further comprising a first light guide plate installed on a side of the first LED light source, and the first LED light source is driven by the DC power to light up the first light guide plate.

3. The power switch structure with both light emission and DC power conversion functions as recited in claim 2, wherein the first light source module is installed in the casing, and the frame further includes a hollow portion provided for installing the first light guide plate.

4. The power switch structure with both light emission and DC power conversion functions as recited in claim 2, wherein the first light guide plate includes at least one first pattern layer formed thereon and provided for the first LED light source to show bright and dark lights through the first pattern layer.

5. The power switch structure with both light emission and DC power conversion functions as recited in claim 2, further comprising a second LED light source installed on a side of the first light guide plate, and electrically coupled to the second DC power contact, for driving the second LED light source and the first LED light source to emit lights of different colors.

6. The power switch structure with both light emission and DC power conversion functions as recited in claim 1, wherein the control switch is one selected from the collection of a capacitive touch panel unit and a mechanical press key unit.

7. The power switch structure with both light emission and DC power conversion functions as recited in claim 1, further comprising a second light source module, and the second light source module having a third LED light source, and being electrically coupled to the second DC power contact, and a second light guide plate installed on a side of the third LED light source, such that the third LED light source can be driven by the DC power to light up the second light guide plate.

8. The power switch structure with both light emission and DC power conversion functions as recited in claim 7, wherein the second light guide plate includes at least one second pattern layer formed thereon, and provided for the third LED light source to show bright and dark lights through the second pattern layer.
