Description

Technical Field

[0001] The utility model relates to the field of stage lights, in particular to a light guide component and a stacked circuit board for stage lights. Background Art

[0002] As a kind of lamp for creating a magnificent stage effect, the volume and weight of stage lights have been significantly increased compared with traditional lamps. At the same time, in order to achieve more lighting display effects and functions, their performance has been further improved. All these require a large number of internal drive circuit boards to control various functions, so a large space is needed to arrange the circuit boards. The circuit boards also generate heat during operation. To ensure normal operation, the circuit boards with light guide columns usually need to be connected to a radiator, and the remaining circuit boards are arranged in a stacked manner to save space; for example, the stacked structure adopted in the patent with the publication number of CN220038374U needs to use the connection seats on the circuit board to arrange the double-layer circuit board. However, in this structure, the height of the connection seats is limited, resulting in a small distance between the double-layer circuit boards, and the high heat of the bottom lamp board circuit board will affect the upper-layer circuit board. Summary of the Utility Model

[0003] In order to solve the above problems of the prior art, the utility model provides a light guide component and a stacked circuit board for stage lights.

[0004] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:

[0005] A light guide component includes a light guide column arranged in a light protection sleeve; the bottom of the light guide column is connected to an LED lamp bead; a condenser cup is arranged at the top of the light protection sleeve; a fixing seat is connected to the middle of the light protection sleeve; and a support column extends downward from the fixing seat.

[0006] Further, a light-emitting lens is arranged at the top of the condenser cup.

[0007] A stacked circuit board for stage lights includes a bottom-layer circuit board; a plurality of the above-mentioned light guide components are connected to the bottom-layer circuit board; a plurality of LED lamp beads are arranged on the bottom-layer circuit board; the bottom of the support column is fixedly connected to the bottom-layer circuit board; and the fixing seat is fixedly connected to a connecting plate.

[0008] Further, the connecting plate is connected to the fixing seat through fixing screws.

[0010] Further, the middle-layer circuit board is fixedly connected to the bottom of the connecting plate.

[0011] Further, the lifting mechanism is fixedly connected to the connecting plate and / or the bottom circuit board.

[0013] Further, the connecting plate is arranged parallel to the bottom circuit board; the connecting plate is connected to the fixing base through a connecting portion arranged at the edge; the fixing base is fixedly connected to the connecting portion through a fixing screw.

[0014] The beneficial effects of the present utility model are as follows: By changing the structure of the light guide component, the light guide component has spaced connection positions, providing installation positions for the installation of double-layer or multi-layer circuit boards, thereby enabling the formation of a sandwich space with a relatively large space. On the one hand, it can be used for the stacked installation of multi-layer circuit boards to avoid the heat dissipation of the bottom circuit board affecting the upper circuit board or the middle circuit board.

[0023] For the embodiments, please refer to Figure 1 as described below:

[0024] A light guide component includes a light guide column 110 disposed within a light protection sleeve 130; the bottom of the light guide column 110 is disposed opposite to an LED lamp bead 100; a condenser cup 140 is provided at the top of the light protection sleeve 130, and a light output lens 150 is provided at the top of the condenser cup 140; a fixing base 120 is connected to the middle of the light protection sleeve 130; the fixing base 120 extends downward to form a support column 121; in one embodiment, a bottom portion of the light guide column 110 is located outside the light protection sleeve 130 to form an exposed portion 111 for rapid heat dissipation; the exposed portion 111 is generally not directly connected to the LED lamp bead 100, and there is a gap between the exposed portion 111 and the LED lamp bead 100, and the gap is about 0.05 - 0.15 mm. Due to the relatively strict control of the gap, the light conducted out by the LED lamp bead 100 is basically conducted into the light guide column 110 and finally exits from the light output lens 150;

[0025] The existence of this gap can slow down the speed of heat transfer from the LED lamp bead 100 to the light guide column 110, reduce the heating rate of the light guide column 110, and the existence of the exposed portion 111 is located below, which is beneficial to rapid heat dissipation and avoids the over - rapid temperature rise of the light guide column 110; the heat generated by the LED lamp bead 100 can be concentrated on the bottom circuit board 200, and the bottom circuit board 200 then relies on a radiator to dissipate heat. Through this structural design, the influence on the upper part of the light guide column 110 is reduced, and further the influence on the space where the connection board 220 is located is reduced;

[0026] The structure of the fixing base 120 in the light guide component provides conditions for the installation of the connection board 220, enabling the connection board 220 to be installed at a relatively far position. The support column 121 is used to support the light guide component, improve the installation stability of the light guide component, and control the distance between the light guide column 110 and the LED lamp bead 100; since the fixing base 120 is provided in the middle of the light protection sleeve 130, it is equivalent to adding a fixing structure in the middle of the light guide component, making the long - strip structure of the light guide component have two fixing positions at the bottom and in the middle. Compared with the structure that is only fixed at the bottom in the prior art, the connection stability of the light guide component of the present utility model is significantly improved, and the anti - dropping ability and the like are enhanced. The setting of the fixing base 120 also provides a basis for the installation of the connection board 220. The connection board 220 connects multiple light guide components into an integrated structure, enhancing the overall consistency and structural strength; in one embodiment, the fixing base 120 and the light protection sleeve 130 can be an integral structure or can be set as a split structure;

[0027] Such as Figure 2As shown, a stacked circuit board for a stage light includes a bottom circuit board 200; a plurality of light guiding components are connected to the bottom circuit board 200; a plurality of LED lamp beads 100 are provided on the bottom circuit board 200; the bottom of the support column 121 is fixedly connected to the bottom circuit board 200; the fixed seat 120 is fixedly connected to the connecting plate 220; in one embodiment, several connecting plates 220 are provided, and the edges of the connecting plates 220 are connected to the fixed seat 120 through connecting parts 221; the fixed seat 120 is fixedly connected to the connecting plate 220 through fixing screws 122; the connecting plate 220 is arranged parallel to the bottom circuit board 200; a sandwich space is formed between the connecting plate 220 and the bottom circuit board 200; the sandwich space can be used to install a middle circuit board 210 to realize the stacked structure setting of the circuit board; through this sandwich space, the circuit board can be arranged and installed more conveniently, and the middle circuit board 210 can be directly fixed to the bottom of the connecting plate 220 to achieve fixation. The advantage of such connection is that it can make the middle circuit board 210 and the bottom circuit board 200 have a sufficient distance. Since the bottom circuit board 200 is installed with LED lamp beads 100, it is the main heat source. Through the spaced arrangement structure, the heat of the bottom circuit board 200 is prevented from affecting the normal operation of the middle circuit board 210.

[0028] Furthermore, the sandwich space can also be used to install a lifting mechanism 300. The lifting mechanism 300 is a device for adjusting the position of the lens assembly above the light guiding component. The setting of the sandwich space enables the motor in the lifting mechanism 300 to have an installation position, thereby realizing the effective utilization of the sandwich space; the installation position of the lifting mechanism 300 can be selected to be fixedly connected to the connecting plate 220 or the bottom circuit board 200, or fixedly connected to both the connecting plate 220 and the bottom circuit board 200 at the same time to improve the connection stability of the lifting structure.

[0029] Furthermore, the connecting plate 220 can be set as a circuit board, which provides more space for installing circuit boards inside the stage light and reduces unnecessary bracket structures. The installation of the connecting plate 220 is realized by using the fixed seat 120 on the light guiding component, which simplifies the structure.

[0030] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, shall be equally included in the patent protection scope of the present invention.
