DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] With regard to the technical means by which the present invention achieves the above-mentioned objects, embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0022] Referring to FIGS. 2 to 4, the present invention provides an inductive illumination structure 4 of a lighting device 3. The lighting device 3 comprises a main body 31 having a lower accommodating chamber 311 and an upper accommodating chamber 312 and a mounting base 32 vertically connected to the main body 31. The mounting base 32 is fixedly coupled to a longitudinal plane 5.

[0023] Referring to FIGS. 5 and 6, the inductive illumination structure 4 includes a moving object sensing unit 41, a lighting unit 42, and a signal processing unit 43. The moving object sensing unit 41 is disposed inside the lower accommodating chamber 311 of the main body 31. The moving object sensing unit 41 includes a compartment seat 412 having a plurality of sector spaces 411 and a plurality of sensors 413 disposed inside the sector spaces 411, respectively. The lighting unit 42 is disposed inside the upper accommodating chamber 312 of the main body 31. The lighting unit 42 includes a multi-segment folding plate 421 and a plurality of light sources 422 disposed on the outer wall of the multi-segment folding plate 421. The signal processing unit 43 is disposed inside a horizontal section 321 of the mounting base 32 of the lighting device 3. The signal processing unit 43 is electrically connected to the sensors 413 and the light sources 422, respectively.

[0024] Referring to FIGS. 2 to 4, a front edge of the lower accommodating chamber 311 is provided with a transparent cover 33. A front edge of the upper accommodating chamber 312 is provided with a lampshade 34. The compartment seat 412 has a semi-circular shape. The compartment seat 412 is equally divided into the sector spaces 411 each gradually enlarged outwardly. The included angle of the sector space 411 may be set to any parameter, such as 45 or 60 or 90 degrees. The light sources 422 correspond in position and in number to the sensors 413.

[0025] Referring to FIGS. 4 and 5, the inductive illumination structure 4 of the lighting device 3 provided by the present invention is implemented. The light sources 422 of the lighting unit 42 correspond in position and in number to the sensors 413 of the moving object sensing unit 41. When the first sensor 413 of the inductive illumination structure 4 detects the presence of the moving object (the moving object is in the sensing range of the first sensor 413), the first light source 422 corresponding to the first sensor 413 is activated by the signal processing unit 43 electrically connected to the first sensor 413 and the light source 422. The first light source 422 provides illumination for the moving object. When the moving object continues to move and the second or third sensor 413 detects the presence of the moving object, the second or third light source 422 corresponding to the second or third sensor 413 can be activated by the signal processing unit 43. The second or third light source 422 sequentially provides illumination for the moving object.

[0026] Referring to FIGS. 5 and 6, the inductive illumination structure 4 of the lighting device 3 of the present invention can accurately provide illumination required for the moving object. The plurality of light sources 422 and the same number of sensors 413 are disposed in the upper accommodating chamber 312 and the lower accommodating chamber 311 of the main body 312, respectively. When a moving object is detected in the sensing range of one of the sensors 413, the signal processing unit 43 receives the sensing signal, and then transmits an activation signal to the light source 422 located above the sensor 413 to accurately provide illumination required for the moving object.

[0027] Referring to FIGS. 5 and 6, the light source 422 of the inductive illumination structure 4 of the present invention is activated automatically and can be changed in response to the change of the position of the moving object. When the moving object is detected in the sensing range of the first sensor 413, the first light source 422 corresponding to the first sensor 413 can be activated by the signal processing unit 43. When the moving object continues to move (the first sensor 413 does not detect the presence of the moving object, the first light source 422 is turned off), the moving object is detected by the second sensor 413, and the second light source 422 corresponding to the second sensor 413 can be activated by the signal processing unit 43. The startup and shutdown of each light source 422 is fully automated.

[0028] Through the description of the above embodiments, it can be seen that the inductive illuminating structure of the lighting device of the present invention has the following effects:

[0029] 1. The present invention can provide the required illumination for moving objects quickly and accurately. It saves the cost of the motor provided in the conventional lighting device and simplifies the components of the lighting device. The inductive illumination structure of the lighting device is innovative and can reduce the manufacturing cost.

[0030] 2. In the present invention, the light sources 422 are located above the corresponding sensors 413, respectively. The light sources 422 and the sensors 413 are disposed inside the main body 312. Each light source 422 receives the signal of the corresponding sensor 413. There is no need for all the light sources to pivot and swing along with the moving object, so that the failure rate of the inductive illumination structure of the lighting device is reduced greatly.

[0031] 3. The light sources 422 of the present invention correspond in position and in number to the sensors 413. The activation of the light source 422 is automated by the signal processing unit 43 and changes in response to changes in the location of the moving object. When the moving object moves from the first sensing area to the second sensing area, the first sensor 413 turns off the first light source 422 because no moving object is detected. The second sensor 413 activates the corresponding second light source 422 when detecting the presence of the moving object. The light sources start the automated inductive illumination structure of the lighting device.

[0032] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
