Abstract

A lighting apparatus includes a light source, a driver, a light housing, an actuator unit, a light passing cover, and an external switch. The driver is used for converting an external power to a driving current supplied to the light source. The light housing is used for disposing the light source and the driver. The actuator unit is connected the driver for configuring a working status of the driver. The light passing cover is fixed to the light housing for a light of the light source to pass through. The external switch is mechanically connected to the actuator via a through hole of the light passing cover for the actuator to generate a control message to the driver. The driver controls the light source according to the control message to configure the working status of the light source.

First claim

The invention claimed is:

a light source;
a driver for converting an external power to a driving current supplied to the light source;
a light housing for disposing the light source and the driver;
an actuator unit connected to the driver for configuring a working status of the driver;
a light passing cover fixed to the light housing for a light of the light source to pass through; and
an external switch mechanically connected to the actuator unit via a through hole of the light passing cover for the actuator unit to generate a control message to the driver, wherein the driver controls the light source according to the control message to configure the working status of the driver, wherein the light source comprises multiple types of LED modules, the multiple types of LED modules have different optical parameters, the driver control the multiple types of LED modules to mix a mixed light corresponding to the working status.

2. The lighting apparatus of claim 1 , wherein the external switch is a pull string with a first portion disposed at an inner side of the light passing cover and a second portion disposed at an exterior side of the light passing cover.

3. The lighting apparatus of claim 2 , wherein an electronic component is attached to the pull string, the electronic component receives power supply from the driver.

4. The lighting apparatus of claim 3 , wherein the electronic component is a light device with power supplied by the driver.

5. The lighting apparatus of claim 3 , wherein the electronic component is a detachable remote control detachable from the pull string, when the detachable remote control is detached from the pull string, the remote control sends the control message to the driver via a wireless circuit of the driver.

6. The lighting apparatus of claim 3 , wherein the pull string has a connector at the exterior side of the light passing cover, the connector is detachably connected to an external device and supplies power generated by the driver to the external device.

7. The lighting apparatus of claim 2 , wherein the driver comprises a driver box and a driver circuit, the actuator unit is a lever connected to a mechanical switch of the driver circuit.

8. The lighting apparatus of claim 7 , wherein a top end of the pull string is fixed to the lever.

9. The lighting apparatus of claim 8 , wherein an opaque unit is used for fixing the top end of the pull string to the lever and covers a through hole for inserting the pull string.

10. The lighting apparatus of claim 1 , wherein the multiple types of LED modules have different color temperatures.

11. The lighting apparatus of claim 1 , wherein the light source comprises multiple light module respectively electrically connected to the driver, the light module has a U-shape plate mounted with multiple LED modules, the U-shape plate has a first arm, a second arm and a connection part, the first arm and the second arm are connected at opposite ends of the connector part.

12. The lighting apparatus of claim 11 , wherein the first arm has a longer length than the second arm.

13. The lighting apparatus of claim 11 , wherein the U-shape plates are fixed to a back cover of the light housing.

14. The lighting apparatus of claim 11 , wherein the U-shape plates are disposed surrounding the driver.

15. The lighting apparatus of claim 14 , wherein the second arm of one U-shape plate has a light source connector plugged to a driver connector of the driver for electrically connecting the LED modules on said one U-shape plate to the driver.

16. The lighting apparatus of claim 1 , wherein the external switch comprises a rotation button for a user to rotate the rotation button to configure the working status of the driver.

17. The lighting apparatus of claim 1 , wherein the external switch comprises a pressing button for a user to press the button to configure the working status of the driver.

18. The lighting apparatus of claim 1 , wherein a back cover of the light housing has a first reflective layer for reflecting the light of the light source to the light passing cover, the first reflective layer has a central opening for placing the driver.
