technical field

The invention relates to the field of optics, in particular to a lamp for producing three-dimensional lighting effects.

Background technique

In modern entertainment venues, TV stations and large-scale performances, it is usually necessary to produce three-dimensional lighting to make the stage effect better. With the progress of the times, the requirements for the effect of three-dimensional lighting are getting higher and higher, and prisms are often used as three-dimensional lighting effects on the stage.

Referring to FIG. 1 , a single-sided prism is commonly used in the prior art, but because of the small light angle of the single-sided prism, the light spots are easily interlaced and unclear, giving people a sense of visual confusion. Especially when using a single-sided polygonal prism, because the number of prisms increases, the mirror area of the prism itself becomes larger, resulting in serious light attenuation and blurring of the spot. Therefore, the lighting effects of the existing single-sided prism stage lamps are relatively poor.

detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

Referring to FIG. 2 , a lamp for generating three-dimensional lighting effects described in this embodiment includes a light source 1 , a reflective bowl 2 , a first optical assembly 4 , a second optical assembly 5 , a double-sided prism 6 , and a third optical assembly 7 . The light source 1 is installed in the reflective bowl 2 . The double-sided prism 6 is installed between the second optical assembly 5 and the third optical assembly 7 . The first optical assembly 4 , the second optical assembly 5 , and the third optical assembly 7 are coaxially arranged sequentially along the main optical axis. The light source 1 is used to generate light, which is focused by the reflective bowl 2, passes through the first optical assembly 4, the second optical assembly 5, the double-sided prism 6, and the third optical assembly 7 in sequence, and then is exported.

The interior of the reflective bowl 2 is hollow and one end is open, and the inner wall 21 of the reflective bowl 2 is an arc surface for focusing the light beam generated by the light source 1 . The reflective bowl 2 can be integrally formed with the light source 1, or the reflective bowl 2 and the light source 1 can also be two separate entities, and the two are detachably connected.

The first optical assembly 4 includes a first adjustment member 42 and a first optical lens 41 mounted on the first adjustment member 42 . The first regulating member 42 defines a first light-transmitting hole (not shown) along its axial direction. The first optical lens 41 is inserted into the corresponding first light-transmitting hole, and the first light-transmitting hole can be cut into two sections. The first optical lens 41 is used to form a parallel beam of light transmitted through the reflective bowl 2 and/or the light source 1 . The first optical lens 41 can reciprocally slide on the first adjusting member 42 along the propagating direction of the main optical axis, so that the light spot becomes clear.

The second optical assembly 5 includes a second optical lens 51 and a second adjusting member 52 for installing the second optical lens 51 . A second light-transmitting hole (not shown) is defined inside the second regulating member 52 along its axial direction. The light can propagate through the second light transmission hole. The second optical lens 51 is mounted on one end of the second adjusting member 52 and covers the second light transmission hole. The second optical lens 51 is driven by the second adjusting member 52 to reciprocate along the central axis, and is used for focusing or diverging the light beam transmitted from the first optical assembly 4 .

Referring to FIG. 3 and FIG. 4 , the double-sided prism 6 is used to form a three-dimensional lighting effect, and the double-sided prism 6 includes a first prism sheet 61 and a second prism sheet 62 disposed opposite to each other. The first prism sheet 61 and the second prism sheet 62 can be fixedly connected by adhesives such as glue, or both can be integrally formed. The number of ribs of the first prism sheet 61 is at least three, and each rib is equally spaced. The first prism sheet 61 is in the shape of a regular polygon. The shape and size of the second prism sheet 62 are the same as that of the first prism sheet 61 . The bottom surfaces of the two prism sheets are overlapped or bonded and fixed. Each prism on the first prism sheet 61 and each prism on the second prism sheet 62 are alternately arranged to bisect each other. The number of prisms of the first prism sheet 61 is half of the number of required light spots.

The third optical component 7 is used to amplify the light beam. The third optical assembly 7 includes a third optical lens 71 and a third optical lens mounting part 72 . The third optical lens mounting part 72 also defines a third light-transmitting hole (not shown) along the axial direction. The third optical lens 71 protrudes from one end of the third optical lens mounting member 72 . The third optical lens 71 completely covers the third light transmission hole. The outer surface of the third optical lens 71 is a convex arc surface. Preferably, the first optical lens 41 , the second optical lens 51 and the third optical lens 71 are all of the prior art, so details are not repeated here.

The lamp for producing three-dimensional lighting effects of the present invention may further include a pattern sheet 3 installed between the light source 1 and the first optical assembly 4 . Preferably, the gobo 3 is placed close to the focus position.

Taking the number of prisms of the first prism sheet as six as an example, the working principle of the lamp for producing three-dimensional lighting effect of the present invention will be described. And referring to Fig. 1 and Fig. 2 in combination, further embodies the effect of the present invention.

After the lamp for generating three-dimensional lighting effect of the present invention is energized or other energy is supplied, the light source emits light. The light passes through the reflective bowl and is focused for the first time by the curved inner wall of the reflective bowl to form a very focused beam of light (optical axis). The gobo can be placed close to the focus position so that the beam of light can pass through the gobo. When the beam of light passing through the pattern sheet passes through the first optical assembly, the position of the first optical lens on the first adjusting member is adjusted to make the light spot clear. When the light beam reaches the predetermined effect, stop adjusting the first optical lens. The light beam passing through the first optical component is then converged and diverged by the second optical component, and then passes through a polygonal prism to form an independent three-dimensional spot, and finally the optical component is enlarged and exported to form a complete optical path.

When no prism is used in the luminaire, the resulting light spot has only a single pattern. However, when the present invention adopts a double-sided prism, the number of patterns generated by the lamp is equal to the sum of the number of prisms in the double-sided prism. For example, when the number of prisms of the first prism sheet and the second prism sheet are both six, the lamp for producing three-dimensional lighting effect of the present invention will produce twelve mutually independent and clear patterns. However, when the existing single-sided prisms produce the same number of patterns, the number of prisms must be equal to the number of patterns, or be the sum of the number of double-sided prisms of the double-sided prism in the present invention. For example, when twelve patterns are to be produced, the number of ribs of the single-sided prism must be twelve prisms to achieve twelve identical patterns.

In addition, when producing the same number of patterns, the number of prisms of each prism sheet using a double-sided prism is reduced by half relative to the prior art, and the included angle between two adjacent prisms on each prism sheet in the double-sided prism is relatively Existing technology will be doubled. Therefore, the use of double-sided prisms can effectively reduce light attenuation, and the generated patterns are independent of each other. Therefore, the lighting effect produced by the lamp for producing three-dimensional lighting effect of the present invention is much better than that of the prior art.

Those skilled in the art can make various other corresponding changes and deformations according to the above-described technical solutions and ideas, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
