Abstract

The utility model provides a projection lamp. The projection lamp comprises a lamp housing (2), a light-emitting body (9), a lamp cap (17), a lamp cap fixing plate (16) connected with the lamp cap (17), and also a fixing support (15) connected with the lamp housing (2); the lamp cap fixing plate (16) is positioned between the two side walls of the fixing support (15); and a length compensation mechanism capable of enabling the lamp cap fixing plate (16) to move up and down relatively to the fixing support (15) and be fixed on the fixing support (15) is arranged between the lamp cap fixing plate (16) and the fixing support (15). The projection lamp has the advantages that light-emitting bodies with different lengths can be conveniently mounted by using the lamp cap fixing plate with certain specification, and the height of the light-focusing point can be kept unchanged throughout.

Description

Projecting Lamp

Technical field:

The utility model relates to a kind of lighting, specifically is a kind of Projecting Lamp.

Background technology:

Projecting Lamp of the prior art in actual use, sometimes the illuminator (illuminating source) that needs to change different capacity reaches the illuminating effect of different brightness, and the length of different capacity illuminator is different usually, its length of the illuminator that power is big more will be long more generally speaking, otherwise, its length of illuminator that power is more little will be short more, the variation of length will directly influence illuminator and be installed in focal point height on the Projecting Lamp, in other words, the height of luminescent center of different length illuminator is different usually, remain the same from beginning to end in order to guarantee the focal point height behind the prior art Projecting Lamp replacing illuminator, make it keep good light efficiency, the way of people's routine all is to add a lamp holder fixed head at lamp holder bottom pad, rely on the height of this piece lamp holder fixed head to come the length of illuminator is compensated, thereby make it can keep original focal point height.But,, therefore, will need the lamp holder fixed head of a plurality of different sizes to match with it for the illuminator of a plurality of different lengths because a kind of lamp holder fixed head of specification can only be applicable to a kind of illuminator of length.

The utility model content:

The technical problems to be solved in the utility model is, provides the lamp holder fixed head of a kind of a kind of specification of need that the different length illuminator just can conveniently be installed and keeps the Projecting Lamp of focal point height.

Technical solution of the present utility model is, a kind of Projecting Lamp with following structure is provided: it comprises lamp housing, illuminator, lamp holder and the lamp holder fixed head that is connected with lamp holder, wherein, it also comprises a fixed support, fixed support is connected with lamp housing, the lamp holder fixed head is provided with one and can makes lamp holder fixed head relative fixed support move up and down and can be fixed on length compensation mechanism on the fixed support between support bracket fastened two side between lamp holder fixed head and the fixed support.

Projecting Lamp described in the utility model, wherein, length compensation mechanism can adopt following structure: be symmetrically arranged with long gain on the fixed support two side, be connected with the set screw that the lamp holder fixed head can be locked on the long gain on the long gain.

Projecting Lamp described in the utility model, wherein, lamp housing left end internal chamber wall is provided with two and is used for the wing plate that is connected with fixed support, and fixed support is connected with wing plate by screw.

After adopting above structure, compared with prior art, the utility model Projecting Lamp has following advantage: can make lamp holder fixed head relative fixed support move up and down and can be fixed on length compensation mechanism on the fixed support owing to be provided with one between the utility model lamp holder fixed head and the fixed support, therefore, the utility model can come the length of different illuminators is compensated by this length compensation mechanism, thereby makes the utility model Projecting Lamp only need a kind of lamp holder fixed head of specification the illuminator of different length just can conveniently be installed and can keep the focal point height constant all the time.
