Abstract

The utility model discloses a searchlight, which fixes the light tube, the back cover and the mirror seat into a whole, and the inner parts of the back cover and the mirror seat are respectively provided with a parabolic reflector and a protective mirror; a xenon lamp used as light source is arranged on the focus of the parabolic reflector, and a spherical reflector or a convex lens is arranged on the light path of the xenon lamp, and the focus of the parabolic reflector, the lighting point of the xenon lamp and the spherical center of the spherical reflector or the convex lens are coincided together. The energy of the xenon lamp is fully used to improve the light chroma and enhance the utilization rate of the light source. The xenon light has good starting property and long service life which increases continuous operation time, and which has important significance in the war circumstance.

Description

Seachlight

The utility model relates to optical instrument---condenser class.

Condenser is widely used in the illumination on aerial ground and sea and search operation, particularly airport illumination and the illumination apparatus on the ship etc. when boarding a plane the night flight land.Existing searchlight; on the parabolic reflector mirror foci, adopt powerful carbon arc lamp; though this lamp source has higher brightness; and has an enough little luminous point; can satisfy the requirement of searchlight; but the only 90 minutes useful life of its carbon-point; so in use must change carbon-point continually, each replacing must be opened bonnet, and is very inconvenient; and because the carbon-point combustion oxidation makes the position of luminous point produce skew; thereby must be equipped with automatic focusing mechanism, in addition, the burning of carbon-point is easy to pollute speculum and protective glass; reduce the transmitance of the reflectivity and the protective glass of speculum, influenced brightness.

The purpose of this utility model is to provide a kind of simplified structure, increases the service life, and can open and have the searchlight of intense light source at any time.

The light source of searchlight of the present utility model is connected with external circuit, adopt high-power, superhigh pressure xenon lamp, be positioned on the focus of parabolic reflector, according to paraboloidal optical characteristics, the light path that xenon lamp can be projected on it is transmitted into the direction that needs illumination again after assembling.Spherical reflector or at least one convex lens can be set on light path simultaneously, the light path that spherical reflector can not directly project on the parabolic reflector xenon lamp another part is launched after spherical reflector turns back to parabolic reflector again, and convex lens can be directly with the infinite distant place of light directive, form illuminating bundle, the light energy that this just utilizes the light source xenon lamp to be sent fully, the utilance of raising light source.

The utility model compared with prior art, and is simple in structure, and the superhigh pressure xenon lamp has very high brightness, compares with the carbon arc lamp of equal-wattage, and its luminous point is little, and surface brightness height, luminous energy are easy to cover at a distance, and its photochromism more approaches sunlight; Xenon lamp has and reaches 500 hours useful life; Xenon lamp has good starting characteristic, and the energy transient starting is with driveing with the pass; The luminous point position of xenon lamp can not change, thereby need not Focusing mechanism, does not also pollute the environment; Spherical reflector and convex lens improve the light source utilance greatly, increase brightness, thereby make the xenon lamp that uses lower-wattage under the situation of same luminous intensity reaching, energy savings.

To describe in further detail according to above-mentioned accompanying drawing embodiment below.

Searchlight (referring to Fig. 1-3) has the fluorescent tube (4) of a metal drum shape, fluorescent tube (4) wall has louvre, fan and so on cooling system is contained in fluorescent tube (4) inwall, and the two ends of fluorescent tube (4) are screwed connection bonnet (1) and microscope base (8) is integral.

Parabolic reflector (2) is housed in the bonnet (1), it is high-power superhigh pressure xenon lamp (3) that the focus of this mirror is provided with the light source that links to each other with external power, xenon lamp (3) is bearing on the tabular lamp socket (5), after regulating xenon lamp (3) luminous point during assembling and parabolic reflector (2) focus overlapping lamp socket (5) is fixed on fluorescent tube (4) inwall.Spherical reflector (7) or at least one convex lens (10) are set on the light path of xenon lamp (3), more than one convex lens (10) can be arranged relatively or arrange in opposite directions, the centre of sphere of spherical reflector (7) or convex lens (10) must coincide with the luminous point of xenon lamp (3), it is fixed on the lamp socket (5) by bearing (6), and the centre of sphere three of the luminous point of the focus of parabolic reflector (2), xenon lamp (3), spherical reflector (7) or convex lens (10) coincides together in other words.Improved the utilance of light source, increased brightness, made the infinite distant place of light directive.

Microscope base is equipped with protective glass on (8), and this protective glass can be spherical mirror (9) or level crossing or by a plurality of sections bonding diverging lens that form of cylinder (11).Spherical mirror (9) and level crossing do not produce deviation to light, only play the protection searchlight.The effect of diverging lens (11) is to provide an illumination than angle pencil of ray.
