Abstract

The invention provides an optical focusing mechanism of a short-arc xenon lamp. The mechanism comprises brackets, a screw rod slide block device and an adjusting device, wherein the brackets comprise a transverse bracket and a longitudinal bracket; the screw rod slide block device is mounted on the transverse bracket; the adjusting device is mounted on the longitudinal bracket; the screw rod slide block device comprises a rotating device and a screw rod; the adjusting device comprises an adjusting rod; the adjusting rod is mounted on the longitudinal bracket by a connection shaft; a push rod is connected with the lower part of the adjusting rod; a lamp fixing device is arranged at the upper part of the adjusting rod and comprises a base; the base is provided with a sliding lamp holder in a sleeving manner; and the upper end of the adjusting rod is fixed on the sliding lamp holder. The mechanism provided by the invention is reasonable in design, and convenient and rapid to operate. The adjustment of a light-emitting focal length of a searchlight product taking the short-arc xenon lamp as a light source can be easily realized.

Description

technical field [0001] The invention relates to an optical focusing mechanism applied to lighting equipment, in particular to an optical focusing mechanism for a short-arc xenon lamp. Background technique [0002] According to the requirements of "GBT24954-2001 High-speed Marine Searchlights for Ships and Marine Technology", marine searchlights can be divided into two types: fixed focal length and adjustable focal length according to whether the focal length is adjustable. At present, the vast majority of searchlights on the domestic market are fixed-focus products, and there are very few searchlights with focal length adjustment devices inside the cavity. [0003] According to the principle of optical reflection, when the illuminant of the searchlight source coincides with the focus of the reflector, the spot area emitted by the searchlight is the smallest, and the luminous intensity of the lamp is the highest; will expand, and its luminous intensity will also decrease, so...
