Abstract
A lighting control device is mounted in a photoflash and comprises a fixing seat and a honeycomb grid installed in said fixing seat. The terminal of an extension of one end of the honeycomb grid has a first installation member, and the other end of the honeycomb grid has a honeycomb member. An annular region of the outer surface of the honeycomb member, which is adjacent to the first installation member, has a second installation member. In application, the first or second installation member is sleeved by the fixing seat to make the photoflash generate a desired lighted area according to requirement. Thereby, the present invention can change the distance between the honeycomb member and the photoflash and adjust the area lighted by the photoflash via varying the installation way of the honeycomb grid.

DETAILED DESCRIPTION OF THE INVENTION
(8) Refer to FIGS. 1-3 for a first embodiment of the present invention. The lighting control device 1 of the present invention comprises a fixing seat 10 and a honeycomb grid 20. In one embodiment, the fixing seat 10 is made of a plastic material. The fixing seat 10 is a cylindrical-shaped fixing seat. The outer rim of one end of the fixing seat 10 has a base-installation member 12 used to install the fixing seat 10 in a base (not shown in some drawings), and the base is further installed in a photoflash (not shown in some drawings). The honeycomb grid 20 is installed in another end of the fixing seat 10. The terminal of the extension of one end of the honeycomb grid 20 has a first installation member 22. Another end of the honeycomb grid 20 has a honeycomb member 24. In one embodiment, the honeycomb member 24 is made of a metallic material. An annular region of the outer surface of the honeycomb member 24, which is near the first installation member 22 has a second installation member 26 being longer than the first installation member 22. Thus, the first installation member 22 neighbors the second installation member 26. In application, the first installation member 22 or the second installation member 26 is sleeved by the fixing seat 10 according to requirement. In the first embodiment, the second installation member 26 is sleeved by the fixing seat 10. Thereby, the distance between the honeycomb member 24 and the photoflash is shorter, and the area lighted by the photoflash is larger.
(9) Refer to FIG. 4 and FIG. 5 for a second embodiment of the present invention. The second embodiment is identical to the first embodiment in structure but different from the first embodiment in that the first installation member 22 is sleeved by the fixing seat 10 to install the honeycomb grid 20 in the fixing seat 10. Thereby, the distance between the honeycomb member 24 and the honeycomb grid 20 is longer, and the area lighted by the photoflash is smaller.
(10) Refer to FIG. 3, FIG. 6, and FIG. 7 for how the lighting control device 1 of the first embodiment is installed in a photoflash 40 through a base 30. No matter whether the first installation member 22 or the second installation member 26 is sleeved by the fixing seat 10, the fixing seat 10 is installed in the base 30 in the same way. Herein, the first embodiment where the second installation member 26 is installed in the fixing seat 10 is used to exemplify the installation of the lighting control device 1 to the base 30. In the embodiment shown in FIG. 3, FIG. 6 and FIG. 7, the combination of the fixing seat 10 and the honeycomb grid 20 is installed in the base 30 through the base-installation member 12 of the fixing seat 10. A fixing member 32 is annularly formed on and protruded from the surface of the base 30. The fixing member 32 directly sleeves the base-installation member 12 of the fixing seat 10, whereby the fixing seat 10 is installed in the fixing member 32 of the base 30 through the base-installation member 12. A mounting member 34 is extended from the lower surface of the base 30 and used to mount the base 30 in the photoflash 40. A light-pervious member 36 is arranged corresponding to the mounting member 34, allowing the light beams of the photoflash 40 to pass through. In one embodiment, a filter 50 is further disposed on the light-pervious member 36. The filter 50 is a color filter. Thereby, the light beams of the photoflash 40 are processed by the filter 50 to provide different lighting effects for the images. In the embodiment, the lighting control device 1 is installed in the base 30, and the base 30 is further mounted in the photoflash 40, whereby the honeycomb member 24 of the lighting control device 1 can control the light beams of the photoflash 40 and provide the photographer with the desired lighting effect.
(11) In conclusion, the present invention varies the installation way of the honeycomb grid to change the distance between the honeycomb member and the photoflash and regulate the area lighted by the photoflash. The present invention is simple to operate, easy to collect, convenient to carry, and less likely to malfunction.
(12) The embodiments described are only to exemplify the present invention but not to limit the scope of the present invention. Any equivalent modification or variation according to the characteristic or spirit of the present invention is to be also included within the scope of the present invention.
