Description

Technical Field

[0001] This utility model belongs to the field of stage lighting, specifically relating to a multi-source integrated light guide module and stage lighting fixture for LED stage lights. Background Technology

[0002] Stage lighting, as a type of lighting fixture specifically designed for stage performances, needs to change its lighting effects according to changes in the stage scene, such as changing the light color or adjusting the brightness. LED light sources, as a crucial light source for stage lighting, are widely used due to their high luminous efficiency, excellent combined rendering effects, energy saving, environmental friendliness, and long lifespan. However, a single LED light source module typically includes multiple packaged LED chips. When the LED light source changes color or increases brightness, the temperature of the LED chips rises, triggering the LED chip's temperature protection mechanism, which automatically reduces the brightness of the LED chips, thus diminishing the stage lighting effect.

[0003] In existing technologies, such as patent document CN210511102U, an LED stage light and its light panel module are disclosed, which includes multiple LED beads, each LED bead including at least two sub-beads, thereby optimizing the arrangement and wiring of the LED beads and reducing the wiring difficulty. However, since each LED bead includes at least two sub-beads, the heat dissipation effect of the sub-beads is reduced. During use, the sub-beads are prone to triggering the temperature protection mechanism, resulting in a decrease in the brightness of the sub-beads and affecting the lighting effect of the stage light. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a multi-source integrated light guide module and stage lighting fixture for LED stage lights. By individually packaging the LED beads, the heat dissipation efficiency of the LED beads is improved, solving the problem of LED bead brightness reduction caused by high temperature triggering high-temperature protection due to excessive temperature.

[0005] This invention is implemented as follows: A multi-source integrated light guide module for LED stage lights includes a light source component, which includes multiple LED bead groups and a light guide component corresponding to each LED bead group. The light guide component covers the LED bead groups, and each LED bead group includes multiple uniformly distributed LED beads, each LED bead being independently packaged. By independently packaging the LED beads, excessive concentration of multiple LED beads is avoided, creating gaps between them to provide channels for air circulation, improving the heat dissipation efficiency of the LED beads, and thus reducing the risk of the LED beads' brightness decreasing due to overheating triggering high-temperature protection. Simultaneously, the independently packaged LED beads allow for the configuration of more types of LED beads and enable independent and combined control of the LED beads, further enriching the lighting effects of the stage lights.

[0006] The light guide assembly includes a mounting base, a light guide sheet, and a light guide opening arranged sequentially. A light guide rod corresponding to the LED bead is inserted into the mounting base. The light guide rod includes an input end near the LED bead and an output end away from the LED bead, and the light guide sheet covers the output end. Since the individually packaged LED beads are dispersed at the light path center of each LED bead, when guiding multiple dispersed LED beads with a single light guide rod, the radial dimension of the light guide rod needs to be increased, thereby expanding the scattering range of light during light guiding and easily leading to excessive dispersion of light during light guiding, reducing the light guiding effect. When guiding light to a single LED bead with a light guide rod corresponding to the LED bead, the radial dimension of the light guide rod only needs to correspond to a single LED bead, reducing the radial dimension of the light guide rod, thereby reducing the scattering range of light during light guiding and improving the light guiding effect.

[0007] The light guide rod gradually increases in size from the light-incident end to the light-outcident end. The mounting base has a mounting groove corresponding to the light guide rod, and the mounting groove contains a snap-fit ​​protrusion adapted to the light guide rod. When the light guide rod is inserted into the mounting groove, the snap-fit ​​protrusion abuts against and limits its position. Since light gradually diffuses after being emitted from the light source, the gradual increase in size of the light guide rod from the light-incident end further adapts its shape to the diffused light, thereby further improving the light guiding effect.

[0008] Preferably, the light source assembly further includes a lamp bead mounting plate, on which the lamp bead groups are mounted. Multiple lamp bead groups are evenly distributed in a ring from the center of the lamp bead mounting plate outwards, avoiding excessive concentration of multiple lamp bead groups that could cause the stage light to form glaring light spots and improving the lighting rendering effect of the stage light.

[0009] Specifically, the mounting base is fixedly connected to the LED bead mounting plate, including a connecting part fixedly connected to the LED bead mounting plate and a mounting part for mounting the light guide rod. The light-emitting end face of the light guide rod is flush with the top surface of the mounting part, and the periphery of the light-emitting end is in contact with the inner wall of the mounting groove. The light-incident end of the light guide rod extends out of the mounting part and is close to the LED bead. When the light-emitting end face of the light guide rod is flush with the top surface of the mounting part, the light guiding effect of the light guide rod is further improved. If the light guide rod is higher than the top surface of the mounting part, light will diffuse outward from the protruding part of the light guide rod, causing some light to fail to exit from the light-emitting end face of the light guide rod, thus causing the light from multiple light guide rods to interfere with each other and reducing the light guiding effect of the light guide rod. If the light-emitting end face of the light guide rod is lower than the top surface of the mounting part, light from the light guide rod will be reflected in the mounting groove, increasing the light loss rate and thus reducing the light guiding effect of the light guide rod.

[0010] Specifically, the connecting part has a perforated side, allowing the LED beads to be exposed on the mounting base, thus enabling the LED beads to have further contact with the air and further improving the heat dissipation efficiency of the LED beads.

[0011] Preferably, the light guide rod is square prism-shaped and made of high-transparency glass; the light guide sheet is made of frosted glass. High-transparency glass has good light transmittance, reducing light loss during light guiding and thus improving the light guiding effect of the light guide rod; the light guide sheet made of frosted glass can convert the transmitted light into parallel light, making the stage light effect more uniform.

[0012] Preferably, the types of LED beads include RGBW four-in-one LED beads, RGBL four-in-one LED beads, single monochrome LED beads, dual-color LED beads (warm and cool colors), and multi-color mixed LED beads.

[0013] Preferably, the lamp bead group includes 2-5 LED lamp beads.

[0014] A stage lighting fixture includes the aforementioned multi-source integrated light guide module for LED stage lights, and further includes a lens module and a zoom module. The light guide module is sandwiched between the lens module and the zoom module. The zoom module includes multiple evenly distributed driving components. The output end of each driving component is connected to the lens module and drives the lens module to reciprocate along the optical path of the light guide module to adjust the focusing effect of the lens module. This allows the focusing effect of the lens module to match the ever-changing stage scene, improving the practicality of the stage lighting fixture.

[0015] Preferably, the zoom module further includes a heat dissipation component, which includes multiple heat dissipation fins. The heat dissipation fins are thermally connected to the LED beads, increasing the heat dissipation area of ​​the LED beads, further improving the heat dissipation efficiency of the LED beads, and further preventing the LED beads from reducing brightness due to high temperature protection.

[0016] Specifically, it also includes a fan module, which includes multiple fans. The air outlets of the fans face the heat sink fins. The fans increase the airflow speed between the heat sink fins, improve the heat dissipation efficiency of the heat sink fins, and thus improve the heat dissipation efficiency of the LED beads, preventing the LED beads from reducing brightness due to high temperature protection.

[0017] The beneficial effects of this utility model are:

[0018] This utility model proposes a multi-source integrated light guide module and stage lighting fixture for LED stage lights. On the one hand, by individually packaging the LED beads, the heat dissipation efficiency of the LED beads is improved, avoiding the LED beads from triggering high-temperature protection due to excessive temperature, which would lead to a decrease in brightness. At the same time, it also allows the LED beads to be controlled independently and in combination, further enriching the lighting effects of the stage lights. On the other hand, by guiding the light of each LED bead individually through a light guide rod corresponding to the LED bead, the radial dimension of the light guide rod is reduced, thereby reducing the scattering range of light during light guiding and improving the light guiding effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1-5 As shown, a multi-source integrated light guide module for LED stage lights includes a light source assembly 11, which includes multiple LED bead groups 112, and a light guide component 12 corresponding to the LED bead groups 112. The light guide component 12 covers the LED bead groups 112. Each LED bead group 112 includes multiple uniformly distributed LED beads 1121, and each LED bead 1121 is independently packaged. By independently packaging the LED beads 1121, excessive concentration of multiple LED beads 1121 is avoided, and gaps are created between the multiple LED beads 1121, providing a channel for air to circulate among them. This improves the heat dissipation efficiency of the LED beads 1121 and reduces the risk of the LED beads 1121 losing brightness due to overheating triggering high-temperature protection. At the same time, the independently packaged LED beads 1121 can be configured with more types of LED beads and can be independently and combined for control, further enriching the lighting effects of the stage lights.

[0031] In this embodiment, the LED bead 1121 is an RGBW four-in-one LED bead 1121.

[0032] In this embodiment, the lamp bead group 112 includes three LED lamp beads 1121.

[0033] The light guide assembly 12 includes a mounting base 121, a light guide sheet 123, and a light guide port 124 arranged sequentially. A light guide rod 122 corresponding to the LED beads 1121 is inserted into the mounting base 121. The light guide rod 122 includes a light-incident end near the LED beads 1121 and a light-outcident end away from the LED beads 1121. The light guide sheet 123 covers the light-outcident end. Since the independently packaged LED beads 1121 are distributed at the light path center of each LED bead 1121, the light guide rod 122 guides multiple LED beads 1121 to their respective light paths. When using scattered LED beads 1121 for light guiding, the radial dimension of the light guide rod 122 needs to be increased, thereby expanding the scattering range of light during light guiding. This can easily lead to excessive dispersion of light during light guiding, reducing the light guiding effect. When using a single LED bead 1121 for light guiding via the light guide rod 122 corresponding to the LED bead 1121, the radial dimension of the light guide rod 122 only needs to correspond to a single LED bead 1121, reducing the radial dimension of the light guide rod 122. This reduces the scattering range of light during light guiding and improves the light guiding effect.

[0034] In this embodiment, the light source assembly 11 further includes a lamp bead mounting plate 111, and the lamp bead group 112 is mounted on the lamp bead mounting plate 111. Multiple lamp bead groups 112 are evenly distributed in a ring from the center of the lamp bead mounting plate 111 outwards, which avoids the excessive concentration of multiple lamp bead groups 112 causing the stage light to form a glaring light spot and improves the lighting rendering effect of the stage light.

[0035] Specifically, the mounting base 121 is fixedly connected to the LED bead mounting plate 111, including a connecting part 1212 fixedly connected to the LED bead mounting plate 111 and a mounting part 1211 for mounting the light guide rod 122. The light-emitting end face of the light guide rod 122 is flush with the top surface of the mounting part 1211, and the periphery of the light-emitting end is in contact with the inner wall of the mounting groove 12111. The light-incident end of the light guide rod 122 extends out of the mounting part 1211 and is close to the LED bead 1121. When the light-emitting end face of the light guide rod 122 is flush with the top surface of the mounting portion 1211, the light guiding effect of the light guide rod 122 is further improved. If the light guide rod 122 is higher than the top surface of the mounting portion 1211, light will diffuse outward from the protruding part of the light guide rod 122, causing some light to fail to exit from the light-emitting end face of the light guide rod 122. This will cause the light from multiple light guide rods 122 to interfere with each other, reducing the light guiding effect of the light guide rod 122. If the light-emitting end face of the light guide rod 122 is lower than the top surface of the mounting portion 1211, the light emitted from the light guide rod 122 will be reflected within the mounting groove 12111, increasing the light loss rate and thus reducing the light guiding effect of the light guide rod 122.

[0036] Specifically, the connecting part 1212 has a hollowed-out periphery, so that the LED lamp bead 1121 is exposed to the mounting base 121, allowing the LED lamp bead 1121 to further contact the air, thereby further improving the heat dissipation efficiency of the LED lamp bead 1121.

[0037] The light guide rod 122 gradually increases in size from the light input end to the light output end. The mounting base 121 is provided with a mounting groove 12111 corresponding to the light guide rod 122. The mounting groove 12111 is provided with a snap-fit ​​protrusion 12112 adapted to the light guide rod 122. When the light guide rod 122 is inserted into the mounting groove 12111, the snap-fit ​​protrusion 12112 abuts against and limits the light guide rod 122. Since light gradually diffuses to the surroundings after being emitted from the light source, the gradual increase in size of the light guide rod 122 from the light input end to the light output end further adapts the shape of the light guide rod 122 to the diffused light, thereby further improving the light guiding effect.

[0038] In this embodiment, the light guide rod 122 is square prism-shaped and made of high-transparency glass; the light guide sheet 123 is made of frosted glass. High-transparency glass has good light transmittance, reducing light loss during light guiding, thereby improving the light guiding effect of the light guide rod 122; the light guide sheet 123 made of frosted glass can convert the transmitted light into parallel light, making the stage light effect more uniform.

[0040] like Figure 6 As shown, this is one embodiment of the present invention. The main technical solution of this embodiment is the same as that of Embodiment 1. Features not explained in this embodiment are explained in Embodiment 1 and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0041] In this embodiment, the lamp bead group 112 includes three LED lamp beads 1121.

[0042] Example 3

[0043] like Figure 7 As shown, a stage lighting fixture includes a multi-source integrated light guide module 1 for LED stage lights as described in Embodiment 1 or Embodiment 2, and further includes a lens module 2 and a zoom module 3. The light guide module 1 is sandwiched between the lens module 2 and the zoom module 3. The zoom module 3 includes a plurality of evenly distributed driving components 31. The output end of the driving component 31 is connected to the lens module 2 and drives the lens module 2 to reciprocate along the light path direction of the light guide module 1 to adjust the focusing effect of the lens module 2, so that the focusing effect of the lens module 2 can match the ever-changing stage scene, thereby improving the practicality of the stage lighting fixture.

[0044] In this embodiment, the zoom module 3 further includes a heat dissipation component 32, which includes multiple heat dissipation fins. The heat dissipation fins are thermally connected to the LED bead 1121, which increases the heat dissipation area of ​​the LED bead 1121, further improves the heat dissipation efficiency of the LED bead 1121, and further avoids the LED bead 1121 from reducing brightness due to high temperature protection.

[0045] Specifically, it also includes a fan module 4, which includes multiple fans 41. The air outlets of the fans 41 face the heat dissipation fins. The fans 41 accelerate the airflow between the heat dissipation fins, improve the heat dissipation efficiency of the heat dissipation fins, and thus improve the heat dissipation efficiency of the LED beads 1121, preventing the LED beads 1121 from reducing brightness due to high temperature protection.
