Abstract

An adaptor, a light source device using the adaptor, and a lighting apparatus using the adaptor are provided. The adaptor includes a main body, a protruding part, and an operating component. The main body includes: a power supply mounting part, a light source mounting part, and a conducting circuit extending from the power supply mounting part to the light source mounting part; the protruding part is operatively movable to a blocking position for blocking the power supply mounting part from being engaged with the power supply module, and a releasing position for releasing the power supply mounting part to be engaged with the power supply module. The operating component is operatively movable on the main body to an on-position and an off-position.

First claim

The invention claimed is:

1. An adaptor for electrically connecting a power supply module with a light-emitting apparatus, comprising:
a main body, comprising:
an outer wall, forming an inner chamber,
a power supply mounting part, located at the outer wall and configured to be engaged with the power supply module;
a light source mounting part, located at the outer wall and disposed opposite to the power supply mounting part, and configured to be engaged with the light-emitting apparatus; and
a conducting circuit, located in the inner chamber and configured to be capable of being turned on and off, and configured to transmit electric power outputted by the power supply module to the light-emitting apparatus, when the power supply mounting part is engaged with the power supply module and the light source mounting part is engaged with the light-emitting apparatus,

a protruding part, movably connected to the main body, wherein the protruding part is operatively movable to a blocking position and a releasing position; when in the blocking position, the protruding part blocks the power supply mounting part from being engaged with the power supply module, and when in the releasing position, the protruding part releases the power supply mounting part to be engaged with the power supply module, and
an operating component, movably connected to the main body and the protruding part, wherein the operating component is operatively movable on the main body to an on-position and an off-position; when the power supply mounting part is engaged with the power supply module, by a resisting force from the power supply module, the protruding part moves to the releasing position and maintains in the releasing position, and the operating component moves to the on-position to turn on the conducting circuit; when the power supply mounting part is separated from the power supply module, the protruding part moves to the blocking position from the releasing position and meanwhile driving the operating component to move from the on-position to the off-position to turn off the conducting circuit.

2. The adaptor according to claim 1 , wherein the operating component is locked with the outer wall when the operating component is in the on-position; the operating component is unlocked from the outer wall when the operating component is in the off-position.

3. The adaptor according to claim 1 , wherein the main body has a longitudinal lengthwise direction along which the operating component is operatively movable on the main body.

4. The adaptor according to claim 3 , wherein the protruding part comprises a first portion and a second portion both extending along the longitudinal lengthwise direction of the main body, the first portion and the second portion are perpendicular connected.

5. The adaptor according to claim 4 , wherein ends of the first portion and the second portion each are provided with a guiding slope.

6. The adaptor according to claim 3 , wherein the main body comprises the outer wall and a sliding groove disposed on the outer wall and extending along the longitudinal lengthwise direction, the operating component is slidably disposed in the sliding groove.

7. The adaptor according to claim 6 , wherein the sliding groove comprises a locking recess, the operating component comprises a locking protrusion, the operating component is capable of operatively driving the locking protrusion to move into the locking recess to limit the operating component in the on-position.

8. The adaptor according to claim 1 , wherein the adaptor comprises an elastic member located between the protruding part and the main body, when the protruding part is in the releasing position, the elastic member provides the protruding part with an acting force which moves the protruding part towards the blocking position.

9. The adaptor according to claim 8 , wherein when the power supply mounting part is separated from the power supply module, the elastic member being compressed provides the protruding part with an acting force to move the protruding part towards the blocking position, so that the protruding part rebounds to the blocking position from the releasing position and meanwhile driving the operating component to move from the on-position to the off-position.

10. The adaptor according to claim 1 , wherein the conducting circuit comprises an on-off switch, the operating component is cooperated with the on-off switch to turn on and turn off the conducting circuit.

11. The adaptor according to claim 10 , wherein the adaptor comprises an elastic pressing piece movably connected to the main body, the operating component operatively drives the pressing piece to move towards or move away from the on-off switch so as to turn on or turn off the on-off switch.

12. A light source device, comprising:
a light-emitting apparatus; and
an adaptor for electrically connecting a power supply module with the light-emitting apparatus, the adapter comprising: a main body that comprises:
an outer wall, forming an inner chamber,
a power supply mounting part, located at the outer wall and configured to be engaged with the power supply module;
a light source mounting part, located at the outer wall and disposed opposite to the power supply mounting part, and configured to be engaged with the light-emitting apparatus; and
a conducting circuit, located in the inner chamber and configured to be capable of being turned on and off, and configured to transmit electric power outputted by the power supply module to the light-emitting apparatus, when the power supply mounting part is engaged with the power supply module and the light source mounting part is engaged with the light-emitting apparatus,

a protruding part, movably connected to the main body, wherein the protruding part is operatively movable to a blocking position and a releasing position; when in the blocking position, the protruding part blocks the power supply mounting part from being engaged with the power supply module, and when in the releasing position, the protruding part releases the power supply mounting part to be engaged with the power supply module, and
an operating component, movably connected to the main body and the protruding part, wherein the operating component is operatively movable on the main body to an on-position and an off-position; when the power supply mounting part is engaged with the power supply module, by a resisting force from the power supply module, the protruding part moves to the releasing position and maintains in the releasing position, and the operating component moves to the on-position to turn on the conducting circuit; when the power supply mounting part is separated from the power supply module, the protruding part moves to the blocking position from the releasing position and meanwhile driving the operating component to move from the on-position to the off-position to turn off the conducting circuit,
wherein the light source mounting part in the adaptor is engaged with the light-emitting apparatus so that the conducting circuit is electrically connected to the light-emitting apparatus.

13. The light source device according to claim 12 , wherein the light-emitting apparatus is a long straight light tube.

14. The light source device according to claim 12 , wherein the adaptor and the light-emitting apparatus are integrally provided.

15. A lighting apparatus, comprising:
a light-emitting apparatus;
