Description

Many minute surfaces stage Projecting Lamp

Technical field

The utility model relates to a kind of stage illumination, lighting light fixture, specifically, is the stage floodlight about a kind of light path member multifaceted reflecting mirror mirror that is deep hood type.

Background technology

Along with the development of social economy with culture, modernized arenas is vigorously built everywhere, but traditional stage lamp is difficult to adapt to the requirement of the stage scale of modernized arenas.Usually, traditional stage illumination, lighting light fixture mainly contains three kinds: first kind is that stage projector, second kind are that stage soft light (or claiming imaging lamp) and the third are the stage signal lamps.Their light source is the row's of employing silk structure all, no matter be the light source of single filament or double filament, only allow filament vertically to light, gradient can not surpass 45 ° otherwise adjacent filament can touch jumping because of the effect of gravity, cause damaging, particularly this row's silk light source light and shade that structure produced is irregular, can form the filament image, on light channel structure, first kind and second kind of stage illumination, lighting light fixture all belong to the transmission-type light channel structure, light source is outwards exported the stage irradiates light by Fresnel lens or convex lens, and light source moves focusing along the optical axis of lens, and the light of output is soft, light and shade is even, and certain projection distance arranged, but foot, because light channel structure is simple, the lens relative aperture is little, cause the utilization rate of light low, more seriously, be subjected to the refraction of the glass of lens own and the absorption of crystal, the light output efficiency of light fixture only be about the total light of light source logical 20%.In order to improve delivery efficiency, the light channel structure of the third stage illumination, lighting light fixture has adopted spherical reflector, this spherical reflector is installed in the lamp outer casing, on this shell, focus adjusting mechanism is housed, it connects mutually with the interior lamp socket of this shell, supporting the lifting of this lamp socket, can move along the optical axis of this spherical reflector along with the adjusting of focus adjusting mechanism, optical effect according to the mat spherical reflector, the brightness of illumination and the effective range of light fixture have been improved, though can raise the efficiency, there is the uneven shortcoming of illuminating ray, particularly the light and shade that produces of filament of light source imaging is uneven and cause it can not be used for carrying out scenic spot personage's illumination.

Summary of the invention

As mentioned above, how to improve the efficient and the soft uniform quality foot technical problem to be solved in the utility model of light of stage illumination, lighting light fixture output light, for this reason, the purpose of this utility model is to provide a kind of many minute surfaces stage Projecting Lamp.

The technical solution of the utility model is as follows:

According to stage illumination, lighting light fixture of the present utility model, it comprises an ostiolate lamp outer casing, be subjected to the supporting of this focus adjusting mechanism and regulate the lamp socket of lifting establishing a focus adjusting mechanism on this shell and in this shell, be provided with one, and insert a parabolic lampshade along the opening of this lamp outer casing, the top central authorities of this lampshade have a through hole, the center through hole that one light source is inserted in this lamp socket and passes this lampshade enters in this lampshade and is positioned on its optical axis, and can move along described optical axis with the adjusting of described focus adjusting mechanism, characteristics are: the above-mentioned throwing face lampshade of a. is made of apart from identical minute surface is one-body molded some lump cokes, is for example connected by 72 minute surfaces to surround a dark hood-shaped bigbore parabolic reflector; B, above-mentioned light source contain some rhizoids, and are the circumferential arrangement of cage type shape.

By shape and cover moldeed depth degree, each piece minute surface is divided into some section pieces that are connected from hood-shaped top to the peristome direction in many minute surfaces of the present utility model.

Lamp outer casing of the present utility model is also established one and can be loaded and unloaded or transparent protective cover to be opened/closed.

Compare with traditional stage illumination, lighting light fixture, the utlity model has substantial characteristics and progress, its advantage is as follows:

1, light source of the present utility model because filament adopts cage shape shape circumferential arrangement, has increased the distance of adjacent filament, therefore both can vertically light, also can level light, be difficult for during use jumping electricity, improved service life because of the filament gravitate produces to collide to cause;

2, light path member of the present utility model adopts hood-shaped deeply, bigbore many minute surfaces of parabola mirror construction, and the light source of cooperation cage shape shape circumferential arrangement filamentray structure, make light fixture output light both have the uniformity of light of traditional Nonopaque type light channel structure, the high efficiency that also has the projection light of conventional reflective light channel structure, stage lighting for equal-wattage, the utility model is compared with traditional transmission-type stage lighting, effectively output light improves three times, compare with the conventional reflective stage lighting, the light and shade inequality that does not exist the filament imaging to cause, this light has reached the even soft light quality of transmission-type light fixture, has reached the efficient of the long drive journey high brightness of reflective lamp again.

Description of drawings

Fig. 1 is a light fixture cross-sectional schematic of the present utility model.

Fig. 2 is an embodiment schematic diagram of the utility model light path member.

Fig. 3 and Fig. 4 are respectively that the master of an embodiment of light source of the present utility model looks schematic diagram and looks up schematic diagram.

The specific embodiment

Provide better embodiment of the utility model according to Fig. 1～Fig. 4 below, and described in detail,, just be not used for limiting claim protection domain of the present utility model so that architectural feature of the present utility model and functional characteristics are described better.

See also Fig. 1; as shown in the figure; the utility model comprises a lamp outer casing 1; it has an opening and connects mutually can load and unload the mode that maybe can open and close with an over cap 6; on this lamp outer casing 1, be provided with a focus adjusting mechanism that is used for focusing 2; and in this lamp outer casing 1, establish a light source socket 3 and insert installation one parabolic lampshade 4 (being the light path member) along the opening of this lamp outer casing 1; the center of top of this lampshade 4 has a through hole 41; one light source 5 is placed on the optical axis of this lampshade 4 and on this through hole 41 is planted its pin this lamp socket 3; this lamp socket 3 is by the supporting of this focus adjusting mechanism, and is subjected to it to regulate lifting and drives on the optical axis that this light source 5 is lampshade 4 at the light path member and move.

See also shown in Figure 2, parabolic lampshade 4 of the present utility model constitutes by the minute surface of some lump coke distances is one-body molded, and in the present embodiment, lampshade 4 is hood-shaped deeply, heavy caliber structure, offer a through hole 41 in its center of top, be divided into the many minute surfaces 42,43 of two joint shapes according to its configuration.

See also Fig. 3 and Fig. 4, light source 5 of the present utility model is a cage shape shape quartz halogen bulbs, in the present embodiment, the 2kw bulb is arranged with circumferential by 12 filaments, therefore, the spacing of adjacent two rhizoids is longer, no matter vertically light or level is lighted and can not touched, this structure also improves the light quality of light source 5.
