Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a linear lamp. Background Technology

[0002] Currently, linear lights on the market typically employ a simple optical structure design, mainly consisting of a linear housing, a built-in light source (such as an LED module), and a light-transmitting lens covering the front of the light source. Traditional lenses often use a flat or single curved structure, which limits their optical control capabilities, resulting in poor light uniformity. After light is refracted by the lens, it easily forms obvious bright and dark stripes or spots on the illuminated surface, affecting the overall lighting effect. This problem is particularly prominent in commercial or residential settings that require highly uniform lighting.

[0003] Most existing products use fully transparent or semi-transparent lenses. Because they cannot effectively block the line of sight to the light source, users inevitably see the internal light-emitting components directly. When the light emitted by the light source passes directly through the lens, the lack of effective secondary optical processing easily causes glare when looking directly at the light source. This is especially true in applications with low installation heights, where such glare can cause significant discomfort to the eyes.

[0004] In summary, existing linear lamps have significant shortcomings in optical performance, and there is an urgent need for a new linear lamp structure that can improve light uniformity and solve the glare problem. Utility Model Content

[0005] The main purpose of this invention is to provide a linear lamp that aims to achieve uniform light output and alleviate glare problems.

[0006] This invention proposes a linear lamp, comprising a linear housing with an opening on its front end face along its length, a light source element installed within the linear housing, and a lens located in front of the light-emitting face of the light source element. The light-incident surface of the lens is planar, and the light-emitting surface of the lens is provided with honeycomb-shaped concave cavities, each concave cavity having a conical inner surface. Multiple inclined surfaces on the inner surface of the conical concave cavities enhance light scattering, increase the light emission angle, and improve light emission uniformity.

[0007] Preferably, the system further includes an outer cover connected to the linear housing, which encloses the lens. The outer cover is made of opaque material and has multiple light-emitting holes. Light emitted from the light source is scattered by the lens and emitted through the light-emitting holes. The outer cover protects the lens, preventing scratches and damage that could affect the light output. By shielding the lens, even if it yellows after prolonged use, the appearance of the linear light remains unaffected, and it is not excessively glaring when viewed directly, effectively mitigating glare.

[0008] Preferably, the outer cover has a U-shaped cross-section, the front end face of the outer cover is spaced apart from the lens, and the light-emitting holes are arranged on the front end face and both sides of the outer cover.

[0009] Preferably, lens slots are provided on both sides of the opening on the front end face of the linear housing along the length direction, the linear housing is open at the end in the length direction, the lens slots extend to the end opening of the linear housing, and the two sides of the lens are inserted into the corresponding lens slots.

[0010] Preferably, the lens slot is composed of a first protrusion and a second protrusion spaced apart. When the lens is inserted into the lens slot, the edge of the light-incident surface of the lens is pressed against the second protrusion, and the first protrusion is pressed against the edge of the light-exit surface of the lens. The second protrusion is formed by recessing from the outside to the inside on the side wall along the length direction of the linear housing, and a strip-shaped groove opening outward is formed on the second protrusion. The cross-section of the strip-shaped groove is an arc shape larger than a semicircle. The opening of the strip-shaped groove facing outward has an outwardly expanding and inwardly contracting "eight"-shaped conical mouth structure. The inwardly contracting end of the conical mouth structure is connected to the strip-shaped groove to form two relatively spaced and slightly convex included angle lines. The two sides of the outer cover are provided with mounting holes one opposite to the conical mouth structure. A screw one is inserted into the strip-shaped groove through the mounting hole one and the conical mouth structure. The screw one is threadedly connected to the included angle line to realize the connection between the outer cover and the linear housing.

[0011] Preferably, an end cap is installed at the terminal opening of the linear housing. The strip groove extends to the terminal opening of the linear housing. The inner wall of the end of the strip groove facing the terminal opening is threaded. The end cap is provided with a second mounting hole opposite to the strip groove. A second screw is inserted into the strip groove through the second mounting hole for threaded connection, thereby connecting the end cap to the linear housing.

[0012] Preferably, the conical cavity is a hexagonal pyramid structure.

[0013] Preferably, both the linear housing and the outer cover are made of thermally conductive metal.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The linear lamp proposed in this invention has a flat light-incident surface on the lens and a honeycomb-shaped arrangement of concave cavities on the light-out surface of the lens. The concave cavities are conical cavities with a conical inner surface. Through multi-angle refraction and scattering of the inner surface of the conical concave cavity, the light is diffused evenly, the light-out angle is increased, and the light-out uniformity is improved.

[0016] Linear lights also include an outer cover. The light emitted by the light source is scattered by the lens and then emitted through the light outlet. The outer cover protects the lens from scratches and impacts that could affect the light output. By shielding the lens, even if it yellows over time, the appearance of the linear light remains unaffected. Furthermore, the light is not overly glaring when viewed directly, effectively mitigating glare. Attached Figure Description

[0024] Reference Figures 1 to 3This utility model provides a linear lamp, including a linear housing 1 with an opening on its front end face along its length, a light source 2 installed inside the linear housing 1, and a lens 3 located in front of the light-emitting face of the light source 2. The light-incident surface of the lens 3 is planar, and the light-emitting surface of the lens 3 is provided with honeycomb-shaped concave cavities 31, each concave cavity having a conical inner surface. The light source 2 is a strip-shaped LED light source board, and the light source 2 emits light towards the lens 3.

[0025] The conical cavity has a hexagonal pyramid structure containing six inclined surfaces. The light emitted by the light source 2 is refracted and scattered at multiple angles through the six inclined surfaces on the inner surface of the conical cavity, thereby uniformly diffusing the light, increasing the light emission angle, and improving the uniformity of light emission.

[0026] The linear housing 1 has an opening at its end in the length direction. A light source slot is provided inside the linear housing 1 along the length direction. The light source slot extends to the end opening of the linear housing 1. The light source component 2 is inserted into the light source slot from the end opening of the linear housing 1, thereby being installed in the light source slot.

[0027] Lens slots are provided on both sides of the opening on the front end face of the linear housing 1 along the length direction. The lens slots extend to the end opening of the linear housing 1. The lens 3 is inserted into the lens slot from the end opening of the linear housing 1, and the two sides of the lens 3 are inserted into the corresponding lens slots.

[0028] An end cap is installed at the end opening of the inline housing 1, and the end cap is installed after the light source 2 and lens 3 are installed.

[0029] An outer cover 4 is installed at the front end of the linear housing 1, enclosing the lens 3. The outer cover 4 is made of opaque material and has multiple light-emitting holes 41. The light emitted by the light source 2 is scattered by the lens 3 and emitted through the light-emitting holes 41. The outer cover 4 protects the lens 3 from scratches and impacts that could affect the light output. By shielding the lens 3 with the outer cover 4, even if the lens 3 yellows after prolonged use, it will not affect the appearance of the linear light; and when the human eye looks directly at the linear light, it will not be too dazzling, effectively alleviating the glare problem.

[0030] The outer cover 4 has a U-shaped cross-section. The front end of the outer cover 4 is separated from the lens 3 by a gap. The light-emitting holes 41 are arranged on the front end and both sides of the outer cover 4, and light is emitted from the light-emitting holes 41 on the front end and both sides of the outer cover 4.

[0031] The linear housing 1 and the outer cover 4 are made of the same material, which ensures the overall integrity of the linear light in terms of appearance.

[0032] Both the linear housing 1 and the outer cover 4 are made of thermally conductive metal. The bottom surface of the light source 2 is attached to the linear housing 1, and the heat generated by the light source 2 when emitting light is dissipated through the linear housing 1. The lower parts of both sides of the outer cover 4 are attached to the sides of the linear housing 1, and they are in contact with each other for heat conduction. Thus, the linear housing 1 and the outer cover 4 together conduct heat for the light source, which can improve the heat dissipation performance.

[0033] The lens slot is composed of a first protrusion 6 and a second protrusion 5 spaced apart. When the lens 3 is inserted into the lens slot, the edge of the light-incident surface of the lens 3 presses against the second protrusion 5, and the first protrusion 6 presses against the edge of the light-exit surface of the lens 3. The second protrusion 5 is formed by recessing from the outside to the inside on the side wall along the length of the linear housing 1, and a strip-shaped groove 51 with an outward opening is formed on the second protrusion 5. The cross-section of the strip-shaped groove 51 is an arc shape larger than a semicircle. The outward opening of the strip-shaped groove 51 is provided with an outwardly expanding and inwardly contracting "eight"-shaped conical mouth structure 52. The inwardly contracting end of the conical mouth structure 52 connects with the strip-shaped groove 51 to form two relatively spaced and slightly convex included angle lines 53. The two sides of the outer cover 4 are provided with mounting holes 42 opposite to the conical mouth structure 52. A screw is inserted into the strip-shaped groove 51 through the mounting holes 42 and the conical mouth structure 52. The screw is threadedly connected to the included angle lines 53 to realize the connection between the outer cover 4 and the linear housing 1.

[0034] The strip groove 51 extends to the end opening of the linear housing 1. The inner wall of the end of the strip groove 51 facing the end opening is provided with a thread 511. The end cover is provided with a mounting hole 2 opposite to the strip groove 51. The screw 2 is inserted into the internal thread of the strip groove 51 through the mounting hole 2 to achieve the connection between the end cover and the linear housing 1.

[0035] The second protrusion 5 is designed to support the lens 3 and also to connect the outer cover 4 and the end cap.
