Abstract
The utility model discloses a functional lamp fitting, particularly a micro prefocus lamp. The utility model is composed of a transformer, a nodal bar, a lamp barrel and a lamp body seat, wherein, the lamp barrel is connected with the lamp body seat; the nodal bar is respectively connected with the transformer and the lamp body seat; the lamp barrel is formed by the connection of an exit pupil lens, a focusing lens ring, and a barrel body; the focusing lens ring is in movable connection with the barrel body in the axial direction; an aperture diaphragm is arranged in the barrel body; an entrance pupil lens can be used as a replacement for the aperture diaphragm; a diaphragm for the elimination of vignette is arranged between the exit pupil lens and the aperture diaphragm in order that luminous spots can have sharp outlines, and stray light outside the luminous spots can be eliminated; the lens can be used as a replacement for the diaphragm for the elimination of vignette.
Description
The utility model relates to a kind of functional lighting, especially miniature spotlight.
Present functional spotlight lamp can only be used for stage, dance hall, lacks the miniature functional spotlight lamp that commerce, building, family etc. locate.And the functional polyalkylene light modulation of stage, dance hall use is specifically long-pending big, and power is big, can not be applicable to place and closely use that spaces such as trade display window, building, family are narrow and small.Existing miniature shot-light is optically focused not, does not become light beam, and its spot size is immutable, and light spot profile is not obvious, does not even become hot spot.
Goal of the invention of the present utility model is to provide a kind of miniature spotlight with high-quality projected spot.
The utility model is made up of transformer (1), pole (2), lamp tube (3) and lamp body seat (4), lamp tube (3) is connected with lamp body seat (4), pole (2) is connected with lamp body seat (4) with transformer (1) respectively, lamp tube (3) is made up of emergent pupil lens (5), focusing lens circle (6) and cylindrical shell (7), focusing lens circle (6) is connected for the axially-displaceable formula with cylindrical shell (7), establishes aperture diaphragm (13) in cylindrical shell (7).The utility model also can adopt the alternative of entrance pupil lens (15) as aperture diaphragm (13).Be further to improve optical quality, the utility model in cylindrical shell (7) emergent pupil lens (5) and aperture diaphragm (13) between be provided with the vignette light hurdle (16) that disappears, this vignette light hurdle (16) that disappears also can lens (17) as the alternative on its vignette light hurdle (16) that disappears.
Compared with prior art, the utlity model has following advantage:
1. because can intercepting reflector and light source, aperture diaphragm in the utility model or entrance pupil lens are incident in the lamp tube light preferably, so hot spot is evenly clear, obvious.In the focusing process, can make clear, the variable size of light spot profile.In addition, because near the aperture diaphragm that is in the reflector focal point has resistant to elevated temperatures advantage,, and has the low advantage of simple structure of cost so the utility model is not subjected near the influence of the high temperature of reflector focus.The vignette light hurdle that disappears can further improve the hot spot image quality, eliminates the outer veiling glare of hot spot.
2. the elasticity coloured paper pressure ring in the utility model have can adorn easily, the advantage of colour changing paper, the color of conversion projected spot easily and light beam.
3. the setting of expanded metal lath both can guarantee heat radiation, can make reflector fix and locate with the tubular pedestal preferably again, had the advantage of being convenient to transport.

Fig. 3 is two a structural representation of the utility model lamp tube example
Fig. 4 is three a structural representation of the utility model lamp tube example
With reference to the accompanying drawings, specific embodiments of the present utility model being done one describes in detail:
The utility model is by transformer (1), pole (2), lamp tube (3) and lamp body seat (4) are formed, lamp tube (3) is connected with lamp body seat (4), pole (2) is connected with body seat (4) with transformer (1) respectively, lamp body seat (4) is by tubular pedestal (8), light source (9) and reflector (10) are formed, between tubular pedestal (8) and reflector (10), be provided with the expanded metal lath (12) of location usefulness, to guarantee that reflector (12) can not make the light source off-axis because of vibration, be convenient to heat radiation simultaneously, lamp tube (3) is by emergent pupil lens (5), focusing lens circle (6) and cylindrical shell (7) are formed, focusing lens circle (6) is connected for the axially-displaceable formula with cylindrical shell (7), in the present embodiment, can adopt guided way and gathering sill to realize, also can adopting is threaded realizes that axially-displaceable connects, the utility model also is provided with aperture diaphragm (13) in cylindrical shell (7), the all right entrance pupil lens (15) of this aperture diaphragm (13) are as its alternative, so that the utility model can form obvious hot spot, the utility model also can be established the vignette light hurdle (16) that disappears between emergent pupil lens (5) in the cylindrical shell (7) and aperture diaphragm (13), the utility model adopts the alternative of lens (17) as the vignette light hurdle (16) that disappears, for ease of changing coloured paper, the place ahead of the utility model emergent pupil lens (5) is provided with elasticity coloured paper pressure ring (14).
Claims (7)
