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.
