Referring to fig. 1, the present embodiment provides a laser lamp, including: a light source part 100, an optical fiber 200, a light uniforming member 300, a sealing part 400, and a light transmitting member 500. The light source part 100 is a laser light source and is used for emitting strong light after being electrified, the optical fiber 200 is provided with a light inlet end 210 and a light outlet end 220, the light inlet end 210 of the optical fiber 200 is connected with the light source part 100, the light outlet end 220 of the optical fiber 200 is connected with the light homogenizing piece 300 and is used for realizing total reflection of light transmitted by the optical fiber 200, the light emitted by the optical fiber 200 through the light homogenizing piece 300 can be homogenized, and the light emitted by the light outlet end 220 of the optical fiber 200 is uniformly diffused after passing through the light homogenizing piece 300. The sealing portion 400 covers the light uniformizing member 300 and the light exit end 220, and seals and protects the light uniformizing member 300 and the light exit end 220 of the optical fiber 200. The light-transmitting member 500 is located on the light-emitting side of the light uniformizing element 300 and is used for transmitting the emitted light of the light uniformizing element 300.

The working principle of the laser lamp provided by the embodiment is as follows: the light source part 100 adopts a laser light source, emits high-brightness strong light after being electrified, the emitted light is conveyed in the optical fiber 200, the optical fiber 200 conducts the light to the light homogenizing piece 300, the light homogenizing piece 300 and the light emitting end 220 are covered by the sealing part 400, the light homogenizing piece 300 and the light emitting end 220 of the optical fiber 200 are protected, and the situation that the end face of the optical fiber 200 is burnt due to the fact that small dust easily causes energy gathering is avoided. The light is totally reflected and homogenized through the light homogenizing part 300, strong light is emitted to the light transmitting component 500 after the homogenized light is emitted from the light homogenizing part 300, and the light penetrating through the light transmitting component 500 is emitted to a stage, so that a better stage lighting effect is realized.

The laser lamp provided by the embodiment has the beneficial effects that: the embodiment conducts the light through the optical fiber 200, so that the light is directly transmitted to the total reflection part from the light source part 100, and the light energy waste caused by that the light is directly scattered on the lamp body and the light is all emitted to the inner wall of the lamp body or is leaked through a gap is avoided. It is thus clear that the embodiment has improved the utilization ratio of the light that the light source sent out, produces the very strong light of luminance through laser light source, shines on the stage after passing the transmission subassembly, satisfies the luminance demand of light on the stage, makes the light on the stage brighter, realizes better stage lighting effect.

Referring to fig. 1 and fig. 2, further, the light source portion 100 includes a three-primary-color tunable light source, which includes a red light source, a green light source and a blue light source; the red light source, the green light source and the blue light source are respectively and independently controlled. At present, a fluorescent powder light source or a xenon lamp is mostly adopted as a light source, the color temperature of white light emitted by the xenon lamp is fixed and cannot be adjusted, and the output energy and the brightness are also limited by the light source. When the tricolor adjustable light source is adopted, the brightness of the red light source, the green light source and the blue light source can be independently adjusted, so that the brightness of three colors can be matched, and light sources with different color temperatures can be obtained. This realizes the adjustable control of the color temperature of the light emitted from the light source unit 100, and increases the practicability of the laser lamp.

The light source part 100 is connected through the optical fiber 200, the light inlet end 210 of the optical fiber 200 can be detachably connected or fixedly connected with the light source part 100, the optical fiber 200 can transmit light in a long distance, the light intensity loss in the transmission process is small, and the working performance is reliable, so that the light source part 100 is easily subjected to modular design through the light transmitting mode of the optical fiber 200, when the light source part 100 is used, the optical fiber 200 is directly connected with the light source part 100, the optical fiber 200 on the light source part 100 can be directly detached when the light source part is not used, and the light source part 100 is very convenient to use through the modular design. And realize long distance transmission through optic fibre 200, not only avoided the light direct can carry out the scattering and the light that leads to all shines on the lamp body inner wall or leaks through the gap and cause the light energy waste, light source part 100 can not set up with the casing of laser lamp moreover. For example, when the housing of the laser lamp is placed on the stage shelf, the light source part 100 may be disposed on the ground, so that the specification of the light source part 100 may not be limited, and thus, the light source part 100 having a large specification may be disposed, thereby realizing high energy output. The traditional light source needs to be fixed on a high shelf, the specification of the traditional light source is limited by the bearing of the shelf, and the high-brightness output cannot be realized.

The energy transmitted in the optical fiber 200 is very high, and the tiny dust on the end surface easily causes energy accumulation, burns out the end surface, and needs to be protected, so the sealing part 400 covers the light homogenizing piece 300 and the light emitting end 220 to effectively protect the light emitting end 220, and in addition, a protective cover is also arranged at the joint of the light inlet end 210 of the optical fiber 200 and the light source, so that the joint of the light inlet end 210 and the light source is sealed to effectively protect the light inlet end 210.

In one embodiment, the light unifying member 300 includes hexagonal rods 310, and the hexagonal rods 310 are disposed in the sealing part 400. The hexagonal rod 310 is specifically a hexagonal solid rod, the hexagonal solid rod is located at the light exit end of the optical fiber 200, and the hexagonal solid rod totally reflects the light emitted from the light exit end 220 of the optical fiber 200, so that light loss is avoided, and the hexagonal solid rod can also homogenize the light emitted from the light exit end 220 of the optical fiber 200, so that the light can be uniformly irradiated in a certain area. By arranging the hexagonal rods 310, the emitted light energy is homogenized and then irradiated onto the light transmission component 500, and the patterns on the light transmission component 500 are irradiated onto a stage.

The hexagonal rod 310 may be fixed in the sealing part 400 by a metal spring, so that the total reflection condition is destroyed at the pressure joint of the metal spring, which causes light to overflow, and the light transmission effect is not good, therefore, in an embodiment, an adhesive part 320 is provided between the hexagonal rod 310 and the sealing part 400, and the hexagonal rod 310 and the sealing part 400 are fixed by adhesive bonding through the adhesive part 320, so that the hexagonal rod 310 is fixed in the sealing part 400 to guide light, and the total reflection condition of light is satisfied between the adhesive part 320 and the hexagonal rod 310, so that light does not leak from the joint of the adhesive part 320 and the hexagonal rod 310. In order to meet the total reflection condition, the bonding part 320 is fixed by low-refractive-index glue, and a total reflection condition is still kept between the low-refractive-index glue and the hexagonal rod 310, so that the overflow optical power is effectively reduced, and the optical energy utilization rate is enhanced. It should be noted that the bonding portion 320 in this embodiment does not melt due to strong light irradiation or heating, which results in glue failure.

In one embodiment, the refractive index of the bonding portion 320 is: 1.3-1.42. In this embodiment, glue with a refractive index of 1.32 is specifically selected, for example, epoxy resin glue. The process is mature, can be directly purchased in the market and is convenient to select. The fixation of the hexagonal rods 310 can be realized through glue, so that the process is simple, the light on the hexagonal rods 310 is prevented from overflowing through total reflection, the loss is reduced, and the light intensity is improved.

The sealing part 400 is mostly of a hollow metal structure, the hollow metal structure has an inner cavity 410, the light homogenizing member 300 and the light incident end 210 of the optical fiber 200 are both arranged in the inner cavity 410, and the joint of the light incident end 210 and the light homogenizing member 300 is sealed through the sealing part 400 of the hollow metal structure. If overflow light exists at the joint of the optical fiber 200 and the light homogenizing member 300, the overflow light can irradiate into the inner cavity 410 of the hollow metal structure and be absorbed by the inner wall of the sealing part 400, so that the overflow light cannot directly irradiate onto the light-transmitting component 500, and the light-transmitting component 500 is prevented from being influenced by the overflow stray light. Since the light source part adopts the laser light source, the light intensity of the laser emitted by the laser light source is very strong, if the sealing part 400 is not adopted, the overflowing stray light can irradiate on the light-transmitting component 500, and the stray light at different angles irradiates on the light-transmitting component 500, so that the patterns transmitted to the stage become fuzzy. Therefore, the sealing member 400 covers the light-emitting end 220 of the optical fiber and the light-uniforming member 300, so that the influence of the overflowing light can be avoided. However, the temperature inside the sealing part 400 is likely to rise after the overflowing light is irradiated to the inner wall of the sealing part 400. Therefore, the sealing portion 400 needs to be improved, specifically as follows:

in one embodiment, a heat dissipation assembly 420 is disposed on the sealing part 400, and the heat dissipation assembly 420 is used for dissipating heat inside the sealing part 400. The heat dissipation unit 420 dissipates heat from the sealing part 400, so that heat in the sealing part 400 is not excessively concentrated, and temperature rise in the sealing part 400 is prevented. The heat sink assembly 420 may take various forms such as a heat sink fan, a heat sink vent, etc. to remove excess heat by heat exchange with air.

In one embodiment, the heat dissipation assembly 420 specifically includes: a window 421 and a lens 422. The window 421 is opened on the surface of the sealing part 400 and communicated with the inside of the sealing part 400; the lens 422 is disposed within the window 421. By connecting the window 421 and the inner cavity 410 in the same way, overflow light can be emitted out of the sealing part 400 through the window 421, and the overflow light is emitted out of the window 421, so that the light intensity in the inner cavity 410 of the sealing part 400 is reduced, energy concentration and temperature rise in the inner cavity 410 are avoided, and the purpose of timely heat dissipation is achieved.

The window 421 is provided on the side of the sealing part 400 so that the overflowing light passing through the window 421 is not irradiated toward the light transmitting member 500. Thus, the overflowing light is emitted through the side surface of the sealing portion 400 and does not emit to the front light-transmitting component 500, so that the influence of stray light on the light-transmitting component 500 is avoided while heat dissipation is realized.

The lens 422 is disposed in the window 421 to seal the window 421, so that the light can penetrate through the window 421 and simultaneously the dust can be prevented from entering the window, thereby achieving a better sealing effect on the sealing part 400. Moreover, the lens 422 can increase the transmission of the overflowing light, so that the emitted overflowing light is transmitted out of the lens 422 as much as possible, thereby reducing the light intensity of the part of the overflowing light in the inner cavity 410 and improving the heat dissipation efficiency.

The light transmission member 500 in this embodiment may be disposed outside the sealing portion 400, or may be disposed on the light exit end 220 surface of the sealing portion 400. When the sealing part 400 is arranged on the outer side, the sealing part 400 can be independently arranged away from the sealing part, the structural form of the sealing part is not limited by the size of the sealing part 400, the structure can be conveniently and adaptively designed, and more light and shadow effects can be realized. When the light transmitting member 500 is disposed on the light emitting end 220 surface of the sealing portion 400, the light transmitting member 500 serves as a part of the sealing portion 400 to seal the light emitting end 220 surface of the sealing portion 400.

In one embodiment, the light transmissive assembly 500 includes a patterned disk 510, the patterned disk 510 including a transparent substrate 511, and a patterned layer 512 disposed on the transparent substrate 511. The pattern disc 510 on the light transmission assembly 500 can be rotatably or fixedly arranged, the light emitted from the light homogenizing member 300 irradiates onto the pattern disc 510, part of the light irradiates onto the stage through the transparent substrate 511, and the other part of the light can be blocked or converted by the pattern layer 512, so that the stage presents a light and shadow effect, and the stage light and shadow requirement is met.

In one embodiment, the transparent substrate 511 is a glass substrate, and the pattern layer 512 is a metal film layer or a dielectric reflective film layer. The glass substrate has mature manufacturing process, low cost and high light transmission, and the metal film layer or the dielectric reflecting film layer can have better reflecting effect on light so that the light is not easy to penetrate, thus different patterns can be presented on the stage.

The traditional pattern disc is usually made of transparent plastic or glass and is hollowed to form a pattern layer, the thickness of the pattern layer formed in the mode is large, when a laser light source is adopted as a light source part, and high-brightness light irradiates on the pattern layer with large thickness, laser interference can be generated, and the formed pattern is unclear. In this embodiment, the pattern layer 512 is a metal film layer or a dielectric reflective film layer plated on the transparent substrate 511, and the thickness of the entire pattern disc 510 can be reduced by plating, so that laser interference is not generated, and the patterns on the stage are clear.

It is easy to think that the pattern layer 512 is not only a metal film layer or a dielectric reflective film layer with a light reflecting effect, but also various optical film layers, such as a light filtering film layer, a light splitting film layer, etc., which allow light to transmit through the pattern layer 512, thereby converting white into other different colors, such as seven colors, a single color, etc. Further enhancing the stage lighting effect.

For example, the pattern layer 512 may also be a metal film layer or a dielectric reflective film layer and an optical film layer, so as to enrich the color of light and shadow.

In one embodiment, the patterned disk 510 is implemented in a rotatable manner to rotate the pattern presented on the patterned disk 510, and therefore, the light transmission assembly 500 further comprises a motor 520, the motor 520 is in driving connection with the patterned disk 510, and the patterned disk 510 is rotated by the driving of the motor 520. For example, a gear is coupled to the pattern disk 510, and the motor 520 drives the pattern disk 510 through the gear. Generally, in order to show a complete light and shadow effect of the pattern disk 510, a roller is mounted on the motor 520, the roller abuts against the outer contour of the pattern disk 510, and the roller is connected with the outer contour by friction force, and the motor 520 drives the roller to rotate and also drives the pattern disk 510 to rotate, so that the motor 520 can be arranged on one radial side of the pattern disk 510, and does not interfere with light transmission of the pattern disk 510 in an axial region.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
