Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lighting fixture capable of emitting light in multiple modes. Background Technology

[0002] Lenses are used in many common lighting fixtures. Existing lenses often use a one-to-one installation method with LED chips, and the light sources are generally scattered and difficult to concentrate. Therefore, the brightness of the light is limited. For example, industrial and mining lamps require higher brightness. The current approach can only increase the power of the lamp, which puts a great strain on the lamp's lifespan and energy consumption. Moreover, existing industrial and mining lamps generally only have one light emission mode, and the light distribution curve angle of the lens is fixed and single, which cannot meet the needs of changing usage environments. Utility Model Content

[0003] This invention provides a lamp that can emit light in multiple modes, which can solve the problems of existing lamps with lenses having difficulty concentrating light, insufficient brightness, and a single light emission mode.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lamp capable of emitting light in multiple modes, comprising a lens plate and a lamp plate disposed on the back of the lens plate. A first spiral lens and a second spiral lens are concentrically disposed on the end face of the lens plate. The first spiral lens and the second spiral lens are arranged adjacent to each other radially. The surfaces of the first spiral lens and the second spiral lens are both arc surfaces, and their light distribution curve angles are different. A plurality of LED beads are arranged on the lamp plate along the center of the cross-section of the first spiral lens and the second spiral lens. By setting two adjacent spiral lenses, the light emitted by the LED beads is concentrated. The light can be refracted twice between the two spiral lenses, changing the angle. This not only results in high brightness and energy saving, but also allows for the formation of multiple light emission modes.

[0005] Preferably, both the first and second spiral lenses are Archimedean spirals, with the spacing between adjacent turns of the Archimedean spiral being strictly consistent, so that the first and second spiral lenses can be tightly nested together.

[0006] Preferably, the deflection angle between the first spiral lens and the second spiral lens is 180°, which can cover a relatively large area.

[0007] Preferably, the light distribution curve angle of the first spiral lens is 60° and the light distribution curve angle of the second spiral lens is 120°. The light emitted from the first and second spiral lenses undergoes mutual secondary refraction to form a light distribution curve angle of 90°. Forming a 90° illumination is beneficial for concentrating the light rays and shooting them vertically downward.

[0008] Preferably, the first spiral lens and the second spiral lens are different colors to meet the needs of various usage environments.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] By setting two adjacent spiral lenses to concentrate the light emitted by the LED beads, the light can be refracted twice between the two spiral lenses, changing the angle. This not only results in high brightness and energy saving, but also allows for the combination of various light-emitting modes. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1-4As shown, this utility model provides a lamp capable of emitting light in multiple modes, including a lens plate 1 and a lamp plate 4 disposed on the back of the lens plate 1. A first spiral lens 2 and a second spiral lens 3 are concentrically disposed on the end face of the lens plate 1. The first spiral lens 2 and the second spiral lens 3 are arranged adjacent to each other radially. The surfaces of the first spiral lens 2 and the second spiral lens 3 are both arc surfaces, and their light distribution curve angles are different. A plurality of LED beads 5 are arranged on the lamp plate 4 along the center of the cross-section of the first spiral lens 2 and the second spiral lens 3. By setting two adjacent spiral lenses, the light emitted by the LED beads 5 is concentrated. The light can be refracted twice between the two spiral lenses, changing the angle. This not only results in high brightness and energy saving, but also allows for the formation of multiple light emission modes.

[0022] Specifically, the first spiral lens 2 and the second spiral lens 3 can be an integral structure with the lens plate 1. The first spiral lens 2 and the second spiral lens 3 have the same width but different thicknesses. The different thicknesses result in different light distribution curve angles. The number of LED beads 5 can be increased or decreased according to requirements. The lengths of the first spiral lens 2 and the second spiral lens 3 should be as long as possible, and they should be arranged adjacent to each other, occupying as much area as possible on the end face of the lens plate 1, resulting in more concentrated light emission. The first spiral lens 2 and the second spiral lens 3 are different colors to meet the needs of various usage environments.

[0023] like Figure 1 As shown, both the first spiral lens 2 and the second spiral lens 3 are Archimedean spirals, with the spacing between adjacent turns of the Archimedean spiral being strictly consistent. This allows the first spiral lens 2 and the second spiral lens 3 to be tightly nested together. Furthermore, the deflection angle between the first spiral lens 2 and the second spiral lens 3 is 180°, enabling the coverage of a relatively large area.

[0024] like Figure 5-7 As shown, the light distribution curve angle of the first spiral lens 2 is 60°, and the light distribution curve angle of the second spiral lens 3 is 120°. The light emitted from the first spiral lens 2 and the second spiral lens 3 forms a light distribution curve angle of 90° after mutual secondary refraction. The formation of 90° illumination is beneficial to concentrate the light and shoot it vertically downward.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
