Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, 2, for a kind of novel optical assembly that is applicable to stage lighting of the present utility model, it comprises lamp plate 20, light source 10, reflecting component 30 and convex lens 60, wherein, light source 10 is fixed on lamp plate 20, according to the illumination needs of stage lighting, this light source 10 can be the LED lamp pearl that is packaged in lamp plate 20 upper surfaces, can be also other light-emitting components, the open column shape body structure of reflecting component 30 for being surrounded by four sidewalls 31, and the taper that this column is big up and small down, the end face of reflecting component 30 and arbitrary cross section are all square, that is to say that four sidewalls 31 of reflecting component 30 are around the central shaft circumference array of column, be the central axis of column and the optical axis coincidence of light source 10, that is to say, the luminous point of light source 10 is positioned on the central axis of reflecting component 30, the upper end of column forms light perforation hole 32, bottom forms incident light hole 33, incident light hole 33 and light perforation hole 32 are communicated with by the hollow space of column, being fixed on lamp plate 20 of reflecting component 30, and its lower surface fits in the upper surface of lamp plate 20, light source 10 is housed inside in incident light hole 33.The inner surface of sidewall 31 forms reflective surface, in order to increase reflecting effect, can be silver-plated at the inner surface of sidewall 31, and certainly, as adopted transparent glass to make reflecting component 30, the outer surface that can be chosen in sidewall 31 is silver-plated, makes the outer surface of sidewall 31 form reflective surface.Above-mentioned convex lens 60 are placed in the top of light perforation hole 32 as lens unit, the axis of these convex lens 60 can be and the optical axis coincidence of light source 10, it is for converging light beam, lens unit can be also multiple optical axises along light source 10 arrange lens, the optical axis coincidence of the axis of lens and light source 10, also can, according to the requirement of stage shadow, different eyeglasses or lens combination be set, to export the shadow matching with stage surface.
Fig. 3 is the light path schematic diagram of above-mentioned optical module, a part of light that the light that light source 10 penetrates and optical axis included angle are less directly penetrates through light perforation hole 32, reflecting through equally distributed four reflectings surface on reflecting component 30 with the larger light of optical axis included angle of other, the space surrounding due to four reflectings surface has certain tapering, therefore, the light also finally being penetrated by light perforation hole 32 through multiple reflections and the angle of optical axis reduce greatly than the angle of initial light and optical axis, thereby realize gathering of light beam, and because reflecting component 30 has larger length, all light that light source 10 sends are all used effectively, there will not be the phenomenon of side light leak.
Reflecting component 30 shown in above-mentioned Fig. 2, it adopts the sidewall 31 of four equal thickness to surround, that is to say, the space that the outer surface of all sidewalls 31 surrounds is a up big and down small cone, the space that the inner surface of all sidewalls 31 surrounds is similarly a up big and down small cone, at the outer surface that utilizes sidewall 31, during as reflective surface, this reflecting component 30 needs to adopt light transmissive materials to make, for example transparent glass; Reflecting component of the present utility model can also be as shown in Figure 5, reflecting component is the cone structure that an employing transparent glass is made, on it, being provided with one has upper surface to be through to the through hole of lower surface, the foursquare length of side that through hole arbitrary cross section becomes all equates, the thickness of sidewall from top to bottom reduces gradually, and the lateral surface of sidewall forms reflective surface.In addition, reflecting component of the present utility model can also be as shown in Figure 4, reflecting component has six equal thickness sidewalls around its central shaft circumference array, certainly, reflecting component can be also to be surrounded by eight, ten sidewalls, and reflecting component sidewall can be n in a word, and wherein n is more than or equal to four even number, thus, on reflecting component, form the even number reflective surface that is more than or equal to four.
In the utility model, for fixing reflecting component 30, can be to fix a fixed cover 40 by screw on lamp plate 20, what reflecting component 30 was fixing be inserted into this fixed cover 40 inside.For light source 10 is normally worked, the lower surface of above-mentioned lamp plate 20 is also installed with multiple fin 50.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
