Description

Technical Field

[0001] This utility model relates to the field of LED visual supplement light technology, specifically to a uniform shadow light source. Background Technology

[0002] In film and television shooting and still photography, creating a three-dimensional and uniform lighting effect is crucial. While traditional single ring lights can eliminate shadows, the light is too flat and lacks a sense of depth. Professional lighting uses multiple independent light fixtures to achieve three-dimensional lighting, but it has inherent drawbacks such as complex system setup, inconvenience in adjusting and synchronizing the angles of each light source, high equipment cost, and poor portability. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] In view of this, the present invention provides a uniform light source, which has main illumination and is equipped with an auxiliary light source that can be flexibly adjusted and can be stably hovered.

[0005] (II) Technical Solution

[0006] The technical solution adopted by this utility model to solve the above problems is:

[0007] A uniform light source includes a main light source and a plurality of auxiliary light sources arranged around the main light source. The main light source includes a main light source housing, a main light source lamp plate disposed within the main light source housing, and a diffuser covering and connected to the main light source housing. A hinge is provided on the outer wall of the main light source housing, the hinge including a first connecting arm and a second connecting arm hinged to each other, and a damping hinge shaft is provided at the hinge point. The auxiliary light sources include an auxiliary light source housing, an auxiliary light source lamp plate installed within the auxiliary light source housing, and a uniform light plate connected to the auxiliary light source housing as a cover. The main light source housing includes a hinge shaft placement groove disposed on the outer wall, the damping hinge shaft is placed in the hinge shaft placement groove, the first connecting arm of the hinge is connected to the main light source housing, and the second connecting arm is connected to the auxiliary light source housing. The first connecting arm of the hinge extends along the height of the main light source housing, and the second connecting arm extends along the height of the auxiliary light source housing.

[0008] In the above technical solution, the main light source serves as the primary lighting source, providing the main illumination and lighting the core area. The auxiliary light source serves as a supplementary lighting source. To eliminate shadows caused by the main light source, the damping hinge shaft of the hinge is placed in the hinge shaft placement slot, making full use of the limited space. The purpose of the hinge is to allow the user to adjust the angle of the auxiliary light source. The damping hinge shaft inside the hinge helps the auxiliary light source maintain the adjusted angle stably, preventing it from loosening and sagging. Furthermore, the height of the first connecting arm extends to the height of the main light source housing, making its connection with the main light source housing more stable. The same applies to the second connecting arm.

[0009] Furthermore, the main light source includes a diffuser covering and connected to the housing of the main light source; the auxiliary light source includes a light-diffusing plate connected to the housing of the auxiliary light source as a cover; the main light source is generally annular, the diffuser includes a light-transmitting surface, and the light-transmitting surface surrounds the center of the main light source to form a frustum side surface; the main light source lamp plate is correspondingly disposed below the light-transmitting surface; the light-emitting surface of the main light source is a conical surface; the light-emitting surface of each auxiliary light source is a fan-shaped ring; and radially extending intervals are provided between each auxiliary light source.

[0010] In the above technical solution, the main light source is set in a ring shape so that it can provide uniform ring illumination without dead angles. The light-transmitting surface is the light-emitting surface of the main light source. The light-emitting surface of the main light source is set in the shape of a frustum around the central axis of the main light source. The light-diffusing plate is the light-emitting surface of the auxiliary light source, which plays a role in guiding the light and improving the light efficiency and quality.

[0011] Furthermore, the main light source housing includes a decorative frame and a base.

[0012] In the above technical solution, the fastening screws fix the base to the bottom of the decorative frame.

[0013] Furthermore, the base is provided with a threaded through hole, which extends from the base to the top wall of the hinge shaft placement slot of the main light source housing, and the fastening screw cooperates with the threaded through hole.

[0014] Furthermore, the bottom end of the fastening screw engages with the hinge; when the fastening screw is screwed into the threaded through hole and moves downward, the bottom end of the fastening screw presses against and fixes the hinge.

[0015] In the above technical solution, after the fastening screw is tightened, its bottom applies a downward pressure force to the hinge, thereby fixing the first connecting arm and the second connecting arm.

[0016] Furthermore, a first thermally conductive pad is provided inside the decorative frame, and the first thermally conductive pad is in contact with the main light source panel. A second thermally conductive pad is provided inside the auxiliary light source housing, and the second thermally conductive pad is in contact with the auxiliary light source panel.

[0017] In the above technical solution, the first thermal pad is attached to the back of the main light source lamp board, and the second thermal pad is attached to the back of the auxiliary light source lamp board, which can prevent the lamp board from overheating and extend the product life.

[0018] Furthermore, a number of auxiliary light sources circumferentially surround the main light source; a radially extending interval is provided between two adjacent auxiliary light sources.

[0019] In the above technical solution, multiple auxiliary light sources are set so that they can supplement light from multiple angles and more thoroughly eliminate shadows around the subject.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0022] 1. The main light source provides a soft main light, which, together with multiple auxiliary light sources that can be adjusted at multiple angles, works together to make the illuminated object receive uniform light, effectively avoiding the problem of harsh projection.

[0023] 2. The damping hinge shaft in the hinge allows the auxiliary light source to be stably suspended at any angle. Users can flexibly adjust the position of the supplementary light according to actual needs. The operation is simple and can be maintained stably. Attached Figure Description
