DETAILED DESCRIPTION

(13) In FIG. 11, a lighting apparatus includes a light source 9901, a driver 9902, a light housing 9903, an actuator unit 9904, a light passing cover 9905, and an external switch 9906.

(14) The driver 9902 is used for converting an external power 9916 to a driving current supplied to the light source 9901.

(15) The light housing 9903 is used for disposing the light source 9901 and the driver 9902. The actuator unit 9904 is connected the driver 9902 for configuring a working status of the driver 9902.

(16) The light passing cover 9905 is fixed to the light housing 9903 for a light 9917 of the light source 9901 to pass through. The external switch 9906 is mechanically connected to the actuator 9904 via a through hole as an opening 99191 of the light passing cover 9905 for the actuator to generate a control message to the driver 9902.

(17) The driver 9902 controls the light source 9901 according to the control message to configure the working status of the light source 9901.

(18) Specifically, users operate the external switch 9906. The external switch 9906 is connected to the actuator 9904, e.g. a lever, a sliding switch, a control circuit board, or a sensor. Users may pull, rotate, press, touch or perform one or more operations on the external switch to change the working status of the driver 9902.

(19) In the following embodiments, there are several embodiment options for designing the external switch.

(20) The actuator is therefore indirectly operated to generate a control message to the driver to change a working status of the driver.

(21) There are various ways for designing the control message mentioned here. For example, the actuator may actively generate a mechanical status change or an electronic signal to the driver as the control message. In some other embodiments, the driver may detect the status of the actuator, e.g. an offset adjustment value, a rotation value, a force applied on the actuator or other design that makes the driver communicating with the actuator so as the driver accordingly determines a configuration of the driver on controlling the light source.

(22) FIG. 12 illustrates a light source example. The light source may include one or more LED modules 9806, 9807. The LED modules 9806, 9807 may be controlled to change their output depending on different working statuses of the driver 9809.

(23) For example, a first working status may be associated with a cool color temperature while a second working status may be associated with a warm color temperature. The multiple LED modules may have different types of LED chips or the same LED chips covered with different fluorescent layers so as to emit different lights. When the driver separately controls the multiple LED modules for changing their output parameters, different mixed light effect may be achieved.

(24) In some embodiments, the external switch 9906 is a pull string with a first portion 9919 disposed at an inner side of the light passing cover 9905 and a second portion 9918 disposed at an exterior side of the light passing cover 9905.

(25) In some embodiments, the actuator 9904 may protrude outside the light passing cover 9905 to engage the external switch 9906 outside the light passing cover 9905.

(26) Specifically, the pull string may be made of textile material, elastic spring material, metal or plastic material, one or multiple strings.

(27) For example, two or more than two pull strings are prepared so that each pull string or their combination of operation may be associated with different settings. When one pull string example is illustrated, persons of ordinary skilled in the art would know how to place two pull strings for pulling one actuator unit or two parts of the same actuator unit. Their drawings are not provided for brevity.

(28) A portion 9919 of the pull string is placed inside the light passing cover while another portion 9918 of the pull string is placed outside the light passing cover 9905. The pull string may be inserted via an opening 99191 of the light passing cover.

(29) The light passing cover may be transparent, translucent or be designed as a diffusion layer, which diffuses and soften light output of the lighting apparatus.

(30) To enhance the structural strength, a cap 9920 may be attached to the light passing cover for passing through the pull string.

(31) In the example of FIG. 11, a column 9915 has a first end connected to the cap 9907 and has a second end connected to another cap 9908. The driver 9902 has a driver box 9914 with a central hole for the column 9915 to pass through. By using such design, the components, including the light passing cover 9905, the light housing 9903, a back cover 9930 of the light housing 9903, the driver 9902 are fixed together with the simple but elegant design.

(32) In some embodiments, an electronic component 9909 is attached to the pull string.

(33) The electronic component 9909 receives power supply from the driver 9902.

(34) In some embodiments, the pull string may be attached or embedded with one or more electronic component 9909.

(35) For example, the pull string may include an electrical wire, a sensor, a switch, a light device, an antenna or even a processor as the electronic component.

(36) For example, when the antenna 9932 is placed on the pull string, particularly at a position outside the light passing cover 9905, a better signal quality is achieved if the driver contains a wireless circuit that needs the antenna to communicate with other devices.

(37) When the antenna is placed outside the light passing cover, signal is not influenced by the light passing cover and kept away from other heat-generating or electro-magnetic wave generating components, thus making signal transmission or receiving quality being enhanced.

(38) In some embodiments, the pull string includes an electrical wire and may have a connector 9910 for connecting an electronic device 9911.

(39) The electronic device 9911 may be fixed or detachably connected to the driver 9902. The electronic device 9911 may be used for send a user command to the driver 9902. In some other embodiments, the electronic device 9911 may be a function module adding a function to the driver 9902. For example, the electronic device 9911 may include a sensor, a processor, a speaker, a camera, a battery or other function unit.

(40) In some embodiments, the electronic component 9909 is a light device with power supplied by the driver.

(41) In some embodiments, the electronic component may be a light device, e.g. a LED indicator with lower strength compared with the light source concealed by the light housing and the light passing cover.

(42) This is particularly helpful in the deep night while the light device on the pull string is taken as a night light providing weak but comfortable light strength in the night.

(43) The light device receives power supply from the driver.

(44) In some embodiments, the pull string may have a socket like an USB socket for connecting to a battery bank when in emergent situation.

(45) There are more variations may be applied based on the innovative concept mentioned above.

(46) In some embodiments, the electronic component is a detachable remote control detachably from the pull string.

(47) 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.

(48) In some embodiments, the electronic component is a remote control that may be operated directly on the pull string. In some embodiments, the electronic component may be further detached when necessary to be used as a remote control.

(49) In other words, the remote control may be attached on the pull string to prevent missing. In some cases, when users want to do so, the remote control may be detached form the lighting apparatus and uses wireless communication to change the working status of the driver.

(50) In some embodiments, the pull string has a connector at the exterior side of the light passing cover.

(51) The connector is detachably connected to an external device and supplies power generated by the driver to the external device.

(52) In some embodiments, the pull string has a connector at the exterior side of the light passing cover.

(53) The connector is detachably connected to an external device and supplies power generated by the driver to the external device.

(54) In some embodiments, the driver includes a driver box 9914 and a driver circuit 99022.

(56) Specifically, the driver may include a driver circuit board 99021. There is a mechanical switch 99023 disposed on the driver circuit board 99021. The mechanical switch 99023 may be structurally connected to the actuator unit 9904, e.g. a lever for sliding or moving the mechanical switch to change a working status of the driver.

(57) In some embodiments, a top end of the pull string is fixed to the lever.

(58) The pull string has a top end and a bottom end. The top end is fixed to the actuator and the bottom end is exposed outside the light passing cover for a user to pull to change a configuration of the driver.

(59) In some embodiments, 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.

(60) The opaque may be an elastic unit 14 in FIG. 6 that is deforms during assembly and recovers to original shape when an external force is released.

(61) When the elastic unit is opaque, the opaque unit prevents light exiting from a through hole for passing the pull string.
