Abstract
The utility model relates to a high-power full-reflection zooming cold light focus lamp consisting of a lamp box, a bulb, a viewfinder, a shape diaphragm groupware and relevant adjusting devices. The utility model is characterized in that the bulb is one type of cold light source bulbs, such as quartz halogen bulb or metal halide gas discharging bulb. The viewfinder consists of a positive viewfinder and a negative viewfinder. The positive viewfinder is a shallow spheroid arc surface, and the negative viewfinder is a ball arc surface. The concaves of the positive and negative viewfinders are against each other. The negative viewfinder is provided with a light outlet and light guiding mirror at the bottom of the central shaft, and a shape diaphragm groupware at the front. The groupware makes the light beam converted into light spots of different shapes; the front of the shape diaphragm groupware is the lens box. The utility model is suitable for use by special lighting lamps in large arenas and has advantages of high light utilization rate, lower energy consumption, high beam quality, and far emission range.
Description
Technical field
The utility model belongs to a kind of lighting, and concrete is a kind of high-power professional special lighting light fixture that is used for occasions such as large-scale stadium, arenas, square.
Background technology
At present, illumination in places such as large stadium, arenas, squares is numerous and diverse with the lamp kind, kind is different, be to adopt incandescent lamp bulb and quartz tungsten halogen lamp bubble as light source mostly, light source and spherical reflector and lens are co-located on the central shaft, constitute transmission type optical system, its shortcoming is that optical efficiency is low, energy consumption is big, and hot spot is inhomogeneous, light of poor quality.Some American-European countries adopt dark ellipsoid minute surface reflective optical system now, and reflective mirror is a glass material; Some product adopts aluminium matter ball-type total-reflection type optical system, and these products all respectively have advantage and practicality, but also come with some shortcomings, as, glass material is frangible dangerous, and the bore that has is less than normal, is unfavorable for bulb heat radiation etc.Therefore, need to propose a kind of more reasonable structure, save the energy, light utilization efficiency is higher, and light quality is better, and the high-power illumination light fixture of novel structure practicality is to satisfy the needs of large stadium.
The utility model content
The purpose of this utility model is at the problems referred to above, a kind of high-power total reflection zoom cold light spotlight is proposed, this lamp just is being provided with, secondary two reflective mirrors, use high intensity cold light supply, the position of light source and speculum is adjustable, has the light utilization efficiency height, the quality height of light, energy savings, hot spot is various adjustable, and the characteristics of light far firing range.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-power total reflection zoom cold light spotlight, mainly comprise lamp box, bulb, reflective mirror, appearance diaphragm assembly and adjusting device, it is characterized in that: described bulb is a kind of in quartz tungsten halogen lamp bubble or the metal-halide gas discharge lamps, reflective mirror is made up of positive reflective mirror and secondary reflective mirror, positive reflective mirror is a shallow spheroid shape cambered surface, secondary reflective mirror is a ball-type cambered surface, just, the concave surface of secondary reflective mirror is relative, central shaft bottom at secondary reflective mirror is provided with a light-emitting window and a leaded light mirror, and this leaded light mirror is a plane-convex lens; The back side at positive reflective mirror is provided with a radiator of being made up of aluminium casting, positive reflective mirror is fixed on the support, this support can move forward and backward adjusting by screw rod A, and secondary reflective mirror and bulb are fixed on the bearing, and this bearing can move forward and backward adjusting by screw rod B; Be provided with appearance diaphragm assembly in the front of secondary reflective mirror, this assembly makes the light beam of ejaculation form various difform hot spots by its shadow shield, appearance plate and iris diaphragm; Be provided with a lens case in the front of appearance diaphragm assembly, be provided with an imaging len and an amplifying lens in this lens case, these two lens are installed in respectively on the mirror holder, and the position of these two lens can move forward and backward adjusting.
Described positive reflective mirror and secondary reflective mirror are made by corrosion resistant plate, scribble organic glaze and cold light deielectric-coating at catoptrical concave surface.
The centre of luminescence of described bulb is positioned at first focus of positive reflective mirror and the center of curvature of secondary reflective mirror.
The utility model is owing to adopted the total-reflection type optical system that is made of the positive reflective mirror of shallow spheroid shape cambered surface and the secondary reflective mirror of ball-type cambered surface, and the centre of luminescence of bulb places on the center of curvature of first focus of positive reflective mirror and secondary reflective mirror, the reflection ray of positive reflective mirror and through the light of secondary mirror reflects, overlap on the positive reflective mirror, repeated reflection is on the secondary reflective mirror central shaft light-emitting window in second focus of shallow spheroid shape cambered surface again, penetrate through transmissive mirror then, so obviously improved the utilization rate of light; Because positive reflective mirror, bulb and secondary reflective mirror are installed on the adjustable support, so guaranteed reflecting effect better; Just, the reflective concave surface of secondary reflective mirror scribbles organic glaze and cold light deielectric-coating, constitutes the catoptrical better effects if of cold light bundle; By reflective mirror, moulding diaphragm assembly and lens case, make that the hot spot moulding of light is more various, the quality and the range of light beam are farther.Therefore, the utility model compared with prior art, it is more reasonable to have structure, the light utilization efficiency height is saved the energy, regulates flexibly, optical quality is good, the advantage of diverse in function.
