Description

Searchlights that enable constant centering of focus and focal length of lamps {lantern to center assambly making constant the lentern focus and the facal distance}

The present invention relates to a searchlight that can be installed at a constant center of focus and focal length of the lamp, and more particularly, an assembly structure in which a lamp installed in a lamp fixing part of a searchlight such as a lantern can be accurately fixed to a center of a reflector. The present invention relates to a searchlight capable of constantly centering the focus and focal length of a lamp so that light can be accurately irradiated forward without being refracted by the reflector.

In general, searchlights, such as lanterns, are used to carry a light while lighting a dark place when needed, and to power the lamp through a battery. There are various types of special portable searchlights for military use, coastal lighting, firefighting firefighting, home lanterns for emergency use, industrial lanterns for factories and companies, and underwater lanterns for use on the seabed. In particular, the portable special searchlight and the underwater lantern of the lantern supplies power to the lamp to irradiate the object of high brightness light.

Such a conventional searchlight is composed of a head, a reflector provided in the head, a lamp connected to a lamp driver, and a lamp case provided with a switch and a handle.

However, such a conventional lantern, that is, a searchlight has a reflector provided in the head, and a lamp is provided and separated in the front part of the ballast or the battery, and flows between the head inner wall so that the lamp cannot be accurately positioned at the focal center of the reflector. In the case of assembling at the production site or reassembling after disassembly, the center of focus of the lamp and the reflector can not be located accurately, which is cumbersome to be fixed after every adjustment. In particular, since the lamp fixing part which has the lamp is in contact with the battery has a structure in contact with the battery, when the lantern shakes during use, the lamp or the lamp driving part flows and the light cannot be accurately positioned at the focal center of the reflector. There is a problem that the irradiation distance is short and the original brightness is significantly reduced.

Therefore, the present invention was devised to solve the above problems, and the present invention provides a lamp fixing part in which the lamp is installed in the ballast housing so that the lamp installed in the lantern fixing part of the search lamp can be accurately positioned at the focal center of the reflector. Assemble with multiple bolts, combine the rear screw of the reflector with the front screw of the lamp fixing part, and connect the socket and the head in order so that the lamp or lamp fixing can be accurately positioned at the center of focus of the reflector at all times without flow. The objective is to provide a searchlight that can be centered on a constant focus and focal length of the lamp.

The present invention is a battery module is mounted on the rear inner side, the top light main body having a female thread on the inner peripheral surface of the front end; A male screw is formed on the outer peripheral surface of the rear end of the case member, and is assembled to the female screw of the main body of the tower lamp. A ballast housing in which a plurality of bolt coupling holes are formed at equal intervals; A handle integrally provided on an outer surface of the case member and equipped with a switch for turning on / off a lamp; A fixture having a lamp base is provided at the center of the front surface, and an internal thread is formed at an inner circumference at regular intervals from the lamp base, and a rear surface of the fixture is provided with a protruding piece in close contact with the sledge of the ballast housing. A lamp fixing part in which a plurality of holes in which bolts are fitted to the protruding pieces are drilled at equal intervals and closely assembled to the ballast housing; The front and rear screw portions are formed on the front and rear surfaces of the cylindrical tube, respectively, and the rear screw portion is coupled to the screw coupling portion of the ballast housing, and the lamp fixing portion is fitted and fixed to the center of the cylindrical tube. A spaced socket; A connector tube is provided on the rear side of the fallopian tube-shaped reflective member, and a screw tube protruding at an end of the connector tube is screwed into the female screw of the lamp fixing part, and a lamp is inserted into the center of the connector tube. A ball reflector; The screw portion formed on the rear inner surface is screwed to the front threaded portion of the socket, the head is provided with a transparent window;

The present invention as described above, so that the lamp is installed in the lamp fixing part of the searchlight can be accurately positioned to the center of the reflector, assembling the lamp fixing part in which the lamp is installed in the ballast housing with a plurality of bolts, the screw portion on the outer surface of the lamp insertion hole Is formed to protrude so that the threaded portion is assembled with the threaded portion of the lamp fixing portion, and connects the socket between the head and the ballast housing so that the lamp or lamp fixing portion can be accurately positioned at the center of focus of the reflecting mirror at all times without flow. As a result, the light is not refracted by the reflector, so that the light is accurately directed toward the front.
