The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The utility model discloses a stage lamp with a light-homogenizing protection function, which comprises the following components in parts by weight in reference to figures 1-2: a light source 10, a light homogenizing lens piece 20, a lens mounting plate 30, a glass pattern plate 40 and/or an effect color filter plate 50 mounted to the luminaire support carrier from top to bottom. It can be understood that the lamp supporting carrier may be a lamp housing and other conventional supporting members, and of course, the lamp further includes common parts such as a circuit board, a wire, a bearing and the like which play a role in ensuring conventional lighting, which are all in the prior art of the lamp and are not in the scope of improvement of the present invention, and are not described again.

The present invention can alternatively or simultaneously set the glass pattern disk 40 and the effect color filter disk 50. Referring to fig. 3-4, the light homogenizing lens 20 is used to uniformly diffuse the highly focused light beam emitted from the light source 10, so as to reduce the temperature of the light beam; the dodging lens member 20 is mounted on the lens mounting plate 30. Referring to fig. 5-6, a plurality of glass pattern plates 41 are fixed on the glass pattern plate 40, and the pattern patterns on different glass pattern plates 41 are different, so that when light beams penetrate through the glass pattern plates 41, light can project corresponding pattern effects. Referring to fig. 7-8, the effective color filter 51 is fixed on the effective color filter disc 50, and when the light beam penetrates through the effective color filter disc, the projected light has a corresponding color filtering effect.

The lens mounting plate 30, the glass pattern plate 40, and the effect color filter plate 50 are rotatably disposed, and specifically, they are all circular plate-shaped structures and can respectively rotate around their central axes. As to how to drive the lens mounting plate 30, the glass pattern plate 40, and the effect color filter plate 50, respectively, it is known that, for example, a rotation gear may be provided at the bottom of the plate, and then the rotation gear may be driven to rotate by a motor, a transmission gear set, or a transmission pulley. Accordingly, the dodging lens member 20, the glass pattern piece 41 and the effect filter 51 can be rotated to the optical path central axis 100 of the light source 10.

Referring to fig. 9-12, when a glass pattern needs to be projected, the glass pattern disc 40 is driven to rotate, the glass pattern sheet 41 is rotated to the optical path central axis 100, and the lens mounting disc 30 is driven to rotate at the same time, so that the dodging lens 20 is also cut into the optical path central axis 100 in a linkage manner, and the highly focused light beam emitted by the light source 10 is projected onto the glass pattern sheet 41 after being uniformly dispersed by the dodging lens 20, thereby avoiding the glass pattern sheet 41 from being burnt out due to high-temperature cracking, improving the uniformity of the light beam and the light spot, and playing a role of dodging. Similarly, referring to fig. 13 to 16, when the effect color filter 51 needs to be projected, the effect color filter disc 50 is driven to rotate, the effect color filter 51 and the dodging lens 20 are rotated to the optical path central axis 100, and the lens mounting disc 30 is driven to rotate at the same time, so that the dodging lens 20 is also linked to cut into the optical path central axis 100, and the light beam is projected onto the effect color filter 51 after being scattered by the dodging lens 20, thereby avoiding the effect color filter 51 from being cracked and burned out, and simultaneously playing a role in improving uniformity of the light beam and the light spots. Of course, when it is necessary to project the glass pattern piece 41 and the effect filter 51 at the same time, the glass pattern piece 41, the effect filter 51, and the light uniformizing lens piece 20 may be cut into the optical path center axis 100 in an interlocking manner.

Because the dodging protection function is provided, the glass pattern sheet 41 and the effect color filter 51 with richer colors and better light transmission effect can be adopted, and compared with the prior art that only a metal pattern sheet can be adopted due to high temperature limitation, the dodging protection device has better color effect and light transmission effect and can meet more stage lighting requirements.

Preferably, referring to fig. 3 to 4, the lens mounting plate 30 is actually a metal pattern plate on which a plurality of metal patterns 31 are provided, specifically, chemically etched using a high temperature resistant metal material, and each of the metal patterns 31 and the dodging lens member 20 is provided in a circumferential direction. Since the metal pattern disk itself can withstand high temperature, when the metal pattern 31 is projected, scattering through the light uniformizing lens member 20 is not required, and therefore, when the metal pattern 31 is projected, the light uniformizing lens member 20 is set on the metal pattern disk, and when the metal pattern 31 is projected, the metal pattern 31 is rotated to the optical path center axis 100, and cutting of the light uniformizing lens member 20 is not required. Therefore, the utility model has the effect of metal pattern projection and has the characteristic of compact structure.

In order to be suitable for more application scenes, the utility model can also be directly used for projection of the initial light beam without any pattern or color filtering treatment. Preferably, the lens mounting plate 30 is provided with a first initial white light hole 32, and the first initial white light hole 32 is a through hole structure; the first initial white light hole 32, the metal pattern 31 and the dodging lens sheet are arranged along the circumferential direction, so that the first initial white light hole 32 can be driven to the optical path central axis 100 by the rotation of the lens mounting plate 30, and at the moment, the light beam directly passes through the lens mounting plate 30 without projecting the metal pattern 31.

Similarly, referring to fig. 7-8, a second initial white hole 52 is formed on the effect color filter 51, and the second initial white hole 52 is a through hole structure. The second initial white hole 52 and the effect filter 51 are arranged along the circumferential direction, so that the second initial white hole 52 can be driven to the optical path central axis 100 by the rotation of the effect filter 50, and at this time, the light beam directly passes through the effect filter 50 without being subjected to the filtering treatment.

Similarly, referring to fig. 5-6, a third initial white light hole 42 is formed on the glass pattern disk 40, and the third initial white light hole 42 is a through hole structure; the third initial white light hole 42 and the glass pattern sheet 41 are arranged along the circumferential direction, so that the rotation of the glass pattern disk 40 can drive the third initial white light hole 42 to the optical path central shaft 100, and at this time, the light beam directly passes through the glass pattern disk 40 to project the glass pattern.

The initial light emitting state of the utility model is as follows: referring to fig. 1-2, the first initial white light hole 32, the second initial white light hole 52, and the third initial white light hole 42 are all located on the central axis 100 of the optical path at the same time, and at this time, the light beam is in the initial projection state. When the glass pattern piece 41 or the effect filter 51 needs to be projected, the corresponding glass pattern piece 41 or the effect filter 51 and the dodging lens member 20 may be rotated and cut into the optical path central axis 100.

In order to further reduce the temperature of the light beam and protect the glass pattern sheet 41 and the effect filter 51, the present invention further includes an infrared heat-insulating sheet 60, and the infrared heat-insulating sheet 60 is fixedly disposed between the light source 10 and the lens mounting plate 30.

Preferably, the present invention further includes a light-emitting lens 70, and the light-emitting lens 70 is disposed above the glass pattern disk 40.

Preferably, the present invention further includes a focus lens 80, and the focus lens 80 is disposed between the glass pattern disk 40 and the light-emitting lens 70.

Preferably, the present invention further comprises a zoom lens 90, and the zoom lens 90 is disposed between the focus lens 80 and the light-emitting lens 70.

Preferably, the dodging lens member 20 is a biconcave lens, which can effectively diverge the highly focused light beam to achieve the dodging effect.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
