Description

Technical Field

[0001] The present invention belongs to the field of stage and landscape lighting fixtures, and particularly relates to the field of battery lamps. Background Art

[0002] Existing battery lamps for stage and landscape lighting generally have a relatively large volume and a single installation method. Most of them adopt a handle suspension type. In terms of adjusting the emission angle direction, it is generally limited to changing the direction of suspension by the handle. However, when the battery lamp is directly placed on a flat stage, the light-emitting angle cannot be changed. At the same time, for existing stage and landscape lighting fixtures, in many cases, it is necessary to perform angle transformation on the emitted light, and angle transformation elements such as diffusion films or diffusion sheets will be used. The installation of traditional diffusion films or diffusion sheets is generally relatively complex and requires special auxiliary fixing parts. The disassembly is also relatively complicated. The entire assembly needs to be disassembled first, and then the diffusion film or diffusion sheet is disassembled.

[0003] Therefore, how to design a battery lamp with multiple installation methods, simple light-emitting angle change, and convenient disassembly and assembly of angle transformation elements is the problem to be solved by this patent. Summary of the Invention

[0004] The purpose of the present invention is to provide a battery lamp to solve the above problems. The purpose of the present invention is achieved through the following technical solutions:

[0005] A battery lamp includes a lamp body (1) and a handle. The lamp body includes a front cover assembly, a lens, an LED lamp board assembly, a circuit board assembly, and a rear cover assembly. The LED lamp board assembly includes an LED light source. It is characterized in that the LED light source is a single LED lamp bead, and the lens is a single lens; the lamp body further includes a rechargeable battery assembly; the front cover assembly includes a plastic front cover, a planar transmissive glass, and an angle transformation element; the rear cover assembly includes a plastic rear cover, an adjusting member, and a magnet; the rechargeable battery is located inside the plastic rear cover; the outer surface of the plastic front cover is provided with an opening for transmitting light; the angle transformation element is movably installed in the accommodation cavity formed by the plastic front cover and the planar transmissive glass; the inner surface of the top of the accommodation cavity is a ramped curve; the plastic rear cover is provided with a groove for installing the adjusting member, a magnet groove for installing the magnet, and a support frame for tying a cord or a strip; the length * width * height dimension of the lamp body ≤ (130mm * 120mm * 100mm).

[0006] Further, the contact surface between the planar transmissive glass and the plastic front cover is a circular convex rib. The outside of the circular convex rib is a glue application groove, and the inside of the circular convex rib is an accommodation cavity for accommodating the angle transformation element.

[0007] Further, the plastic rear cover is a box-shaped body with one side open, and the groove, the magnet groove, and the support frame are respectively distributed on the outer surface of the bottom of the plastic rear cover.

[0008] Further, it is characterized in that the height of the adjusting member exposed on the outer surface of the bottom of the plastic rear cover is adjustable, and the adjusting member can be completely accommodated in the groove when the height is minimized.

[0009] Further, the depth of the magnet groove is greater than the thickness of the magnet.

[0010] Further, the magnet is a cuboid and is located directly above the support frame.

[0011] Further, the opening on the outer surface of the plastic front cover is circular, the main body of the angle conversion element is a circular flat plate or a hemispherical cover, the material of the angle conversion element is acrylic or PC, and the diameter of the opening is greater than the diameter of the main body of the angle conversion element.

[0012] Further, the opening is provided with multiple positioning holes facing outward, the outer edge of the angle conversion element is provided with the same number of positioning feet as the positioning holes of the opening, and the diameter of the circle formed by the connection of the multiple positioning holes is greater than the diameter of the circle formed by the connection of the multiple positioning feet.

[0013] Further, the diameter of the circle formed by the connection of the multiple positioning feet is greater than the diameter of the opening.

[0014] Further, the circular flat plate is provided with a plurality of hand-held holes.

[0015] Compared with the existing stage lamps, the present technical solution has the following obvious advantages:

[0016] 1 - Small volume and rechargeable: The length * width * height dimensions of the lamp body ≤ (130mm * 120mm * 100mm), which is very small in stage and landscape lamps; at the same time, it comes with a built-in battery, can work normally without connecting to the mains power, and is rechargeable;

[0017] 2 - Diversified installation methods: In addition to the conventional handle suspension mode, it can also adopt the magnet adsorption iron plate mode, and multiple lamps can be directly placed on an iron plate; or directly pass through with ropes, Velcro, etc. and then tie them to a tubular object;

[0018] 3 - Simple light output angle adjustment structure: The placement angle of the lamp can be directly changed by adjusting the height of the adjusting member, so as to adjust the projection angle of the emitted light.

[0019] 4 - The angle conversion element can be installed and disassembled directly and separately, without being bundled with other parts for disassembly and assembly;

[0020] The 5-angle transformation element is inserted into the accommodation cavity formed by the plastic front cover and the planar transmissive glass through the positioning holes, and then rotated by hand. Since the inner surface of the top of the accommodation cavity is a ramped curve, that is, the activity space of the angle transformation element in the accommodation cavity gradually narrows, the angle transformation element can be automatically fastened without loosening, and no other fixing method is required.

Detailed Embodiment

[0031] The innovative points of the present invention will be further described below with reference to the drawings.

[0032] As shown in the attached Figure 1-6As shown in the figure, a battery lamp includes a lamp body (20) and a handle (10). The lamp body (20) includes a front cover assembly (30), a lens (40), an LED lamp board assembly (60), a circuit board assembly (50), and a rear cover assembly (80). The LED lamp board assembly (60) includes an LED light source. Among them, the LED light source is a single LED lamp bead (61), and the lens is a single lens (40). The lamp body (20) further includes a rechargeable battery assembly (70). The front cover assembly (30) includes a plastic front cover (1), a planar transmissive glass (3), and an angle conversion element (2). The rear cover assembly (80) includes a plastic rear cover (5), an adjusting member (6), and a magnet (7). The rechargeable battery (70) is located inside the plastic rear cover (5). The outer surface of the plastic front cover (1) is provided with an opening (11) for transmitting light. The angle conversion element (2) is movably installed in the accommodation cavity (4) formed by the plastic front cover (1) and the planar transmissive glass (3). The inner surface of the top of the accommodation cavity (4) is a ramped curve (12). The plastic rear cover (80) is provided with a groove (51) for installing the adjusting member (6), a magnet groove (53) for installing the magnet (7), and a support frame (52) for tying a cord or a strip. The length * width * height dimensions of the lamp body (2) ≤ (130mm * 120mm * 100mm).

[0033] The beneficial effects of the above technical solution are as follows: A battery lamp with a small volume is provided. Under this design, while the lamp body (20) can meet the installation space of various functional components, the volume of the lamp body (10) will not be too large and the weight will not be too heavy, so that it is more conducive to magnet adsorption installation and the binding installation of a cord or a strip. When the length * width * height dimensions of the lamp body are 130mm * 120mm * 100mm, a relatively balanced point is reached. If the volume is larger, it will cause an increase in the weight of the lamp body, which is not conducive to magnet adsorption installation and the binding installation of a cord or a strip. And it can be understood that the smaller the size of the lamp body (20), the better. At the same time, when the angle conversion element (2) is rotatably installed in the accommodation cavity (4), when it rotates to the bottom position of the ramped curve (12), it will automatically snap into the bottom position due to the narrowing of the moving space without any screw fixing structure. When it is necessary to replace different angle conversion elements (2), rotate the angle conversion element (2) in the reverse direction to rotate the angle conversion element (2) from the position with a small gap of the ramped curve (12) to the position with a large gap.

[0034] As a preferred embodiment, the contact surface between the planar transmissive glass (3) and the plastic front cover (1) is an annular convex rib (14). The outer side of the annular convex rib (14) is a glue application groove (13), and the inner side of the annular convex rib (14) is a receiving cavity (4) for accommodating the angle conversion element (2). The beneficial effect of this technical solution is that the fixation problem of the planar transmissive glass (3) and the installation problem of the angle conversion element (2) are simultaneously solved by the annular convex rib (14), making the structure extremely simplified.

[0035] As a preferred embodiment, the plastic rear cover (5) is a box-shaped body with one open side. The groove (51), the magnet groove (53), and the support frame (52) are respectively distributed on the outer surface of the bottom of the plastic rear cover (5). The beneficial effect of this technical solution is that the space at the bottom of the plastic rear cover (5) is fully utilized without additional structural design on other surfaces of the plastic rear cover (5). At the same time, since the fixing method of the lamp is generally related to the bottom of the plastic rear cover (5), it is more convenient and direct to concentrate the groove (51), the magnet groove (53), and the support frame (52) on the plastic rear cover (5).

[0036] Specifically, the height of the adjusting member (6) exposed on the outer surface of the bottom of the plastic rear cover (5) is adjustable. The adjusting member (6) can be completely accommodated in the groove (51) when the height is minimized. The beneficial effect of this technical solution is that when the lamp does not need to adjust the height, the adjusting member (6) will not affect other functions and uses of the lamp.

[0037] Specifically, the depth of the magnet groove (53) is greater than the thickness of the magnet (7). The beneficial effect of this technical solution is that when the lamp does not require magnet adsorption installation, the magnet (7) will not affect other functions and uses of the lamp.

[0038] Specifically, the magnet (7) is a cuboid and is located directly above the support frame (52). The beneficial effect of this technical solution is that when a cord or strip passes through the gap below the support frame (52) and is then tied, the support frame (52) and the magnet (7) are wound together, enabling the overlap of the two installation methods of magnet adsorption installation and tying installation.

[0039] As a preferred embodiment, the opening (11) on the outer surface of the plastic front cover (1) is circular, and the diameter of the opening (11) is greater than the body diameter of the angle conversion element (2); the material of the angle conversion element (2) is acrylic or PC, and the body of the angle conversion element (2) is a circular flat plate or a hemispherical cover. The beneficial effect of this technical solution is that the acrylic or PC material has good light transmittance. Different angle conversion elements (2) can be used according to different angle requirements, and the brightness loss of the emitted light is still within the controllable range; at the same time, the diameter of the opening (11) is greater than the body diameter of the angle conversion element (2), so that when the angle conversion element (2) is directly placed on the planar transmissive glass (3), it automatically enters the accommodation cavity (4) formed by the plastic front cover (1) and the planar transmissive glass (3), which is more conducive to installation.

[0040] As a preferred embodiment, the opening (11) is provided with three positioning holes (111) facing outward. The outer edge of the angle conversion element (2) is provided with positioning feet (21) having the same number as the opening positioning holes (111), and the diameter of the circle formed by the connection of the three positioning holes (111) is greater than the diameter of the circle formed by the connection of the three positioning feet (21). The beneficial effect of this technical solution is that it is convenient for the positioning and installation of the angle conversion element (2) on the front cover. It can be understood that the number of the positioning holes (111) or the positioning feet (21) can also be one, two or four, and their functions are the same as those of the three positioning holes (111) in the appendix Figure 3 There is no difference.

[0041] Furthermore, the diameter of the circle formed by the connection of the three positioning feet (21) is greater than the diameter of the opening (11). The beneficial effect of this technical solution is that the positioning feet (21) are clamped more tightly on the ramped curve (12) in the accommodation cavity (4). Otherwise, if the diameter of the circle formed by the three positioning feet (21) is too small, the part of the positioning feet (21) stuck in the ramped curve (12) of the accommodation cavity (4) is too little, and it is easy to loosen when encountering vibration or impact.

[0042] As a preferred embodiment, the circular flat plate-shaped angle conversion element (2) is provided with 3 holding holes (22). The beneficial effect of this technical solution is that by grasping the angle conversion element (2) through the 3 holding holes (22), it is easier to hold, place and rotate the angle conversion element (2), making the whole operation process more convenient. It can be understood that the number of holding holes is 3, which is the easiest to be operated by human hands. When the number of holding holes is 2 or 4, their functions are the same as those of 3.

[0043] As shown in the appendix Figure 7The schematic diagram is a diagram of adjusting the light output angle of the battery lamp by means of an adjusting member (6), wherein the adjusting member is preferably a hand screw. When placed normally, the battery lamp is perpendicular to the ground, and the hand screw is completely hidden in the groove (51) without any support or angle adjustment function; when the light output angle of the battery lamp needs to be changed, the hand screw is screwed out of the groove (51), and the screw head of the hand screw plays the role of supporting the lamp. The extension length of the hand screw is adjusted accordingly according to the light output angle of the battery lamp required. This method is effective in that the method of changing the light output angle of the battery lamp is extremely simple, fast, and effective, and can be adjusted anytime and anywhere according to the needs.

[0044] As attached Figure 8 The figure is a schematic diagram of a battery lamp installed on an iron plate (9c). The installation can be completed by directly adsorbing the magnet (7) on the back cover of the battery lamp onto the iron plate (9c). Moreover, multiple battery lamps can be adsorbed on one iron plate at the same time for use together. This lamp installation method is also a very simple and quick lamp installation method.

[0045] As attached Figure 9 This is an embodiment of a battery lamp installed on a fixing tube (9a). When the fixing frame of the performance venue is a slender tube, because the battery lamp of the present design is light and small, the lamp can be tied to the fixing tube (9a) by Velcro (9b) or a rope passing through the supporting frame (52) of the battery lamp without worrying about loosening.

[0046] The above embodiments are only to further illustrate the technical solution of the present invention, but not to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
