Description
Technical field
The present invention relates to the optical focusing mechanism being applied on lighting apparatus, particularly a kind of short arc xenon lamp optical focusing
Mechanism.
Background technology
According to《GBT24954-2001 ships and marine technical high speed marine searchlight》Requirement, whether may be used according to focal length
Adjusting, marine searchlight can be divided into focal length is fixed and the class product of focus adjustable formula two.Searchlight on domestic market is big absolutely
Majority is the fixed product of focal length, also has only a few that the inside cavity of searchlight is provided with focal length adjustment device.
According to optical reflection principle, when the illuminator of searchlight light source overlaps with the focus of speculum, searchlight transmitting
The facula area gone out is minimum, the luminous intensity highest of light fixture；When focus of the light source luminescent body along straight deviation speculum, searchlighting
The facula area of lamp be will be enlarged by, and its luminous intensity is also reduced, so facula area is inversely proportional with the luminous intensity of light fixture.
Searchlight product needs root sometimes when the long distance illuminations such as night flight, lifesaving and warning and target search task is performed
Adjust the range of exposures of light fixture in time according to field condition（Facula area）.But the searchlight product that focal length is fixed is due to its focal length
Cannot be adjusted so such product can only be scanned for fixed facula area, this will bring many to search mission
Inconvenience.And the searchlight that focal length adjustment device is built in lamp chamber also has its obvious shortcoming：Searchlight in normal work, due to
Greatly, the temperature inside lamp chamber can be more than 90 DEG C, so after light fixture can only be waited to be stopped and cool down for the caloric value of its light source
Lamp chamber could be opened carries out the adjustment of focal length to it.So on the one hand cannot Real Time Observation searchlight hot spot adjustment situation, separately
On the one hand the quality time of search mission can also be delayed.
The content of the invention
The technical problems to be solved by the invention are directed to the luminous focal length of searchlight product in the prior art and fix and adjust
A kind of two built-in problems of coke installation, there is provided the more rational short arc xenon lamp optical focusing mechanism of new structure.
The technical problems to be solved by the invention are realized by following technical scheme.The present invention is a kind of short arc
Xenon lamp optical focusing mechanism, is characterized in：
The mechanism includes support, screw mandrel slide block device and adjusting means；Described support include connection horizontal support and
Longitudinal carrier；Screw mandrel slide block device is arranged on horizontal support, and adjusting means is arranged on longitudinal carrier；
Described screw mandrel slide block device includes tumbler and screw mandrel, and the power output of tumbler is connected with screw mandrel,
Sliding block is installed on screw mandrel, push rod is fixed with sliding block；
Described adjusting means includes adjusting rod, and adjusting rod is arranged on longitudinal carrier by connecting shaft, and push rod is connected to
On the bottom of adjusting rod, the top of adjusting rod is provided with lamp fixing device, and described lamp fixing device includes base, covered on base
Equipped with lamp socket is slided, the upper end of adjusting rod is fixed on slip lamp socket.
Of the present invention kind of short arc xenon lamp optical focusing mechanism, further preferred technical scheme is：
First, described tumbler is reducing motor, and reducing motor is connected by shaft coupling with screw mandrel.Or, it is described
Tumbler is rotated handle and is connected with screw mandrel by shaft coupling to rotate handle.So, the present invention just have manual focusing or from
2 kinds of selections of dynamic focusing.
2nd, the middle part of adjusting rod is arranged on the middle part of longitudinal carrier by connecting shaft；
3rd, described push rod front portion is provided with bending part, and the perforate for being provided with and coordinating with bending part, bending are asked under longitudinal carrier
Portion is plugged in perforate；
4th, described base is provided with the slot of some outward openings, and described slip lamp socket is provided with some inserted links,
Every inserted link is correspondingly arranged in a slot；
5th, described slot and inserted link are respectively preferably 3；
6th, described horizontal support and longitudinal carrier preferred vertical are set.
Lighted because short arc xenon lamp is 360 °, so searchlight product needed is gathered by optical mirror to it
It is burnt.Optical mirror is parabolic curve（）Rotate a circle what is formed around x-axis.According to the optics of parabolic mirror
Property, when light source center is located at the focal point of speculum, light source light after the reflected mirror reflection of light that focus sends is put down
Row is projected, and in this case, luminous energy is converged to greatest extent, and its irradiation facula area is minimum.If light source is not in reflection
The focal point of mirror, will spread after the reflected mirror reflection of light that now light source sends, and its irradiation facula area will expand.
The present invention mainly enables short arc xenon lamp to carry out the movement of left and right in the horizontal direction by a whole set of mechanism.It is logical
Change xenon lamp illuminator is crossed with the relative position of optical reflection mirror foci to adjust the irradiation facula area of searchlight.Focusing master
If changing the relative position of light source luminescent body and optical reflection mirror foci to realize.The present invention is by the corresponding transmission of design
Mechanism realizes the horizontal rectilinear motion of short arc xenon lamp.With reference to the overall structure feature of searchlight product, the present invention selects silk
Bar slide block mechanism coordinates corresponding transmission device to realize focusing function.
Compared with prior art, what technical solution of the present invention was brought has the beneficial effect that：Mechanism of the present invention is reasonable in design, behaviour
Make convenient and swift.The adjustment of the luminous focal length of searchlight product with short arc xenon lamp as light source can easily be realized.Not only make
Searchlight product can at any time adjust irradiation facula area when performing and searching and rescuing with screening mission according to actual conditions, while passing through
Focus adjusting mechanism is external, also ensure that crewman easily and timely can be adjusted in focusing.It is not only due to reduce and is performing
Because the time that dismounting lamp holder is caused wastes during search and rescue task, and also improve the security of product.
