Abstract

A light tube apparatus includes a light passing tube, a light strip, first cap end, a second cap end, a driver circuit board and a manual switch. The light passing tube are connected with the first cap end and the second cap end on opposite sides of the light passing tube. The manual switch is a fixed to the first cap end. The driver circuit board is at least partly enclosed by the first cap end. The manual switch has a switch sheath and a sliding switch. When a user moves the switch sheath, the sliding switch is moved by the switch sheath to change a position of the sliding switch for changing an operation parameter of the driver circuit.

Claims (23)

1. A light tube apparatus, comprising:

a light passing tube;

a light strip enclosed by the light passing tube emitting a light through the light passing tube;

a first cap end and a second cap end fixed to two opposite ends of the light passing tube;

a driver circuit board comprising a driver circuit, the driver circuit board being at least partly enclosed by the first cap end; and

a manual switch fixed to the first cap end, the manual switch having a switch sheath and a sliding switch, wherein the sliding switch is mounted on the driver circuit board, the first cap end has a switch opening, the switch sheath is inserted through the switch opening to connect to the sliding switch, when a user moves the switch sheath, the sliding switch is moved by the switch sheath to change a position of the sliding switch for changing an operation parameter of the driver circuit, wherein the switch sheath has a receiver groove for enclosing a handle inserted into the receiver groove, wherein the switch sheath has an elastic reverse hook deformed when the switch sheath is inserted into the switch opening and a shape of the reverse hook is elastically recovered when the switch sheath is already plugged to connect to the sliding switch.

2. The light tube apparatus of claim 1 , wherein the first cap end has a guiding groove for the driver circuit board to move along the guiding groove to a predetermined assembled position to align the sliding switch to align with the switch opening to connect to the switch sheath.

3. The light tube apparatus of claim 2 , wherein the first cap end has a stop rib for stopping movement of the driver circuit board along the sliding groove when the driver circuit board is inserted to reach the predetermined assembled position.

4. The light tube apparatus of claim 1 , wherein the switch sheath has a first wing plate and a second wing plate on opposite sides of the switch sheath, when the switch sheath is moved along the switch opening, the first wing plate and the second wing plate keeps the switch opening sealed.

5. The light tube apparatus of claim 4 , wherein the first wing plate and the second wing plate are positioned at different heights with respect to a switch top of the switch sheath.

6. The light tube apparatus of claim 1 , wherein the switch sheath has a first bottom wall and a second bottom wall arranged on opposite sides of the switch sheath, the first bottom wall, the second bottom wall and the reverse hook together enclose the sliding switch to move the sliding switch.

7. The light tube apparatus of claim 1 , wherein there are multiple types of the switch sheath to be selected to inserted into the switch opening, each type of the switch sheath corresponds to an operation status of the light strip.

8. The light tube apparatus of claim 7 , wherein the driver circuit detects the type of the inserted switch sheath to determine an optical parameter of the light strip.

9. The light tube apparatus of claim 8 , wherein the optical parameter comprises a mixed color temperature rendered by multiple LED modules of the light strip.

10. The light tube apparatus of claim 1 , wherein the switch sheath has a function circuit electrically connected to the driver circuit to expand a function of the switch circuit.

11. The light tube apparatus of claim 10 , wherein the function circuit comprises a wireless circuit for routing a message received by communicating with an external device.

12. The light tube apparatus of claim 10 , wherein the function circuit comprises an antenna electrically connected to the driver circuit.

13. The light tube apparatus of claim 1 , wherein the switch sheath has a switch top to be touched by a user to move the switch sheath.

14. The light tube apparatus of claim 13 , wherein the switch top has a sub-switch for selecting a working status to control the driver circuit.

15. The light tube apparatus of claim 14 , wherein the sub-switch is a button.

16. The light tube apparatus of claim 1 , wherein the first cap end has a rotating structure for rotating an angle of the switch sheath with respect to the driver circuit board.

17. The light tube apparatus of claim 1 , wherein the second cap end has a supplemental switch for providing a supplemental control of the driver circuit.

18. The light tube apparatus of claim 1 , wherein the switch sheath has a light indicator for indicating a working status assigned by the driver circuit.
