Description

Technical Field

[0001] The present invention relates to the technical field of garage LED lights, in particular to an up-and-down light-emitting lens and a lamp. Background Art

[0002] In recent years, most indoor parking lots and underground parking lots have started to use LED lights. Compared with traditional lighting fixtures, LED lights are more energy-efficient and environmentally friendly. Since indoor and underground parking lots do not receive natural light, in an environment with poor lighting, garage lights must not only meet the ground illuminance for normal vehicle driving, but also reduce the impact of glare on the human eye.

[0003] The existing ways for garage lights to achieve lighting mainly include: direct lighting and indirect lighting. In direct lighting, the garage light directly emits downward light through a downward light-emitting lens or a downward light-emitting cover; however, there is a lack of upward light to supplement the background brightness in the airspace of the parking lot, and the anti-glare effect is inferior to that of garage lights with upward light. In indirect lighting, while the garage light emits downward light through a downward light-emitting lens or a downward light-emitting cover, an upward light-emitting lens is added above the lamp to emit upward light; although the presence of upward light can reduce the glare effect, it also increases structures such as the upward light-emitting aluminum substrate, the upward light-emitting lens, and the upward light-emitting lamp beads of the lamp, increasing the cost and making the structure complex. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an up-and-down light-emitting lens and a lamp, without additionally increasing the structure of the upward light-emitting lens, and only generating reflected and refracted upward light through a single downward light-emitting lens, so as to achieve an indirect lighting effect and be able to achieve an anti-glare effect with a more concise structure.

[0005] An up-and-down light-emitting lens includes a lens body, and a first light bulb structure, a second light bulb structure, and a light guide structure are arranged on the lens body; wherein,

[0006] The number of the first light bulb structures is multiple, and the multiple first light bulb structures are closely arranged around the center of the lens body to form a first light bulb layer with the center of the lens body as the center of the circle; each first light bulb structure has a light inlet and a light-emitting surface, and the light-emitting surface is a convex arc.

[0007] The number of the second light bulb structures is multiple, and the multiple second light bulb structures are closely arranged around the second light bulb layer to form a second light bulb layer; each second light bulb structure has a light inlet and a light-emitting surface, and the light-emitting surface is a convex arc and has a downward groove.

[0008] The number of the light guiding structures is one or more, and the light guiding structures are arranged around the second light bulb layer; each light guiding structure includes a first light guiding surface adjacent to the outermost second light bulb of the second light bulb layer, a second light guiding surface adjacent to the first light guiding surface, and a third light guiding surface adjacent to the second light guiding surface;

[0009] Light rays are emitted from the light emitting surfaces of the first light bulb structure and / or the second light bulb structure, pass through the first light guiding surface, the second light guiding surface, and the third light guiding surface, and then are emitted to the upper side of the lens body.

[0010] Preferably, the first light guiding surface is parallel to the light incident port direction of the second light bulb and intersects with the extension line of the light emitting surface of the second light bulb;

[0011] Preferably, the second light guiding surface is perpendicularly arranged relative to the first light guiding surface;

[0012] Preferably, the third light guiding surface is at the edge of the lens body and has a plurality of folded edges, and at least one surface of the folded edges is inclined upward;

[0013] Preferably, the first light bulb layer includes two or more of the first light bulb structures; the second light bulb layer includes two or more of the second light bulb structures;

[0014] Preferably, the lens body is in any one of a regular polygon, an irregular polygon, a triangle, a circle or an ellipse;

[0015] Preferably, a specular reflection material or an electroplated bright surface material is further arranged on the lens body;

[0016] Preferably, the lens body is made of any one or more of a plastic material, a glass material, and a metal material; the surface treatment of the lens body includes any one or more of texturing, frosting, electroplating or reflective paper back glue;

[0017] A lamp includes a lamp body and the above-mentioned up and down light emitting lens; the up and down light emitting lens is installed on the lamp body.

[0018] For the up and down light emitting lens and the lamp provided by the present invention, the first light bulb structure can form a down light with Type VS light distribution, and then through the light guiding structure, a part of the light rays can form an up light with a certain proportion. The structure is concise and the light control is efficient; the second light bulb structure is arranged on the periphery of the first light bulb structure, and can realize Type VS light distribution. When the light rays enter the light guiding structure for total reflection and refraction, an up light of more than 5% can be realized.

[0019] Compared with the prior art, the present technical solution can simultaneously achieve the two functions of upward emission and downward emission, without the need to additionally add an upward-emitting lens and its derivative structure products, thereby reducing costs and increasing efficiency. At the same time, it can meet the scene application function and has higher visual comfort. For example, after adding upward-emitting light to the garage light lens, it can not only play a decorative role in illuminating the ceiling, but also supplement the background brightness of the entire parking lot environment, weaken the contrast between light and dark in the entire environment, increase visual comfort, and create a good parking environment.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Provide an up-and-down shooting light lens, as Figures 1 to 11 shown, including: a lens body 1, and a first light bulb structure 2, a second light bulb structure 3 and a light guide structure 4 are arranged on the lens body. Among them, the light bulb structure is also called the lens optical structure.

[0037] Specifically, the number of the first light bulb structures is multiple, and the multiple first light bulb structures are closely arranged around the center of the lens body to form a first light bulb layer; each first light bulb structure has a light inlet 21 and a light-emitting surface 22, and the light-emitting surface is a convex arc. The first light bulb structures are distributed inside the lens body, and can achieve TypeV / Type VS light distribution. Its light emission is relatively uniform (as Figure 5 shown), and can achieve the uniformity of the illuminance on the garage floor, and ensure the good lighting environment requirements for vehicle driving in the underground parking lot.

[0038] It should be noted that the Type type of the lamp light distribution is a form of the spatial distribution of the luminous intensity emitted by a lamp. The TypeV light distribution type is generally applicable to places with relatively low installation heights (such as parking lots). It is required that the installation height of the lamp is low, and the light coverage range is relatively large. Generally, there are two shapes of light hitting the ground, one is a circular light spot (TypeV), and the other is a square light spot (TypeVS).

[0039] The number of the second light bulb structures is multiple, and the multiple second light bulb structures are closely arranged around the second light bulb layer to form a second light bulb layer; each second light bulb structure has a light inlet 31 and a light-emitting surface 32, and the light-emitting surface is a convex arc and has a downward groove 33. The second light bulbs are distributed outside the first light bulb layer, and can achieve TypeV / Type VS light distribution. The luminous intensity is mainly concentrated around the light distribution (as Figure 8 shown), and can generate a relatively large luminous intensity to enter the lens light guide structure to generate more upward shooting light, and weaken the glare degree felt by the human eye.

[0040] The number of light guiding structures is one or more, that is, the light guiding structures can be a single one arranged around the second light bulb, or multiple ones arranged around the second light bulb layer. Each light guiding structure includes a first light guiding surface 41 adjacent to the outermost second light bulb of the second light bulb layer, a second light guiding surface 42 adjacent to the first light guiding surface, and a third light guiding surface 43 adjacent to the second light guiding surface. The light rays are emitted from the light emitting surface of the outermost second light bulb of the first light bulb and / or the second light bulb layer, pass through the first light guiding surface, the second light guiding surface, and the third light guiding surface, and then are emitted to the upper side of the lens body. Taking the light emission of the second light bulb structure light guiding structure as an example, the light emission effect is as Figure 11 shown. At the same time, the schematic diagram of the light emission of the entire up-and-down light emitting lens can be seen in Figure 12 .

[0041] Furthermore, the first light guiding surface is parallel to the light inlet direction of the second light bulb and intersects with the extension line of the light emitting surface of the second light bulb. The second light guiding surface is perpendicularly arranged relative to the first light guiding surface. The third light guiding surface is at the edge of the lens body and has a plurality of folded edges 44, and at least one surface of the folded edges is inclined upward. With this setting, when the light rays enter the light guiding structure again, total reflection and refraction can occur, so that more than 5% of the upward-emitted light can be achieved, reaching the optimal effect.

[0042] Furthermore, the specific shape of the lens body can be any one of a regular polygon, an irregular polygon, a triangle, a circle or an ellipse, which is not limited here.

[0043] Furthermore, a specular reflection material or an electroplated bright surface material is also provided on the lens body to improve the reflection effect.

[0044] Furthermore, the material of the lens body is not limited either. For example, any one or more of plastic materials, glass materials, and metal materials can be used; the surface treatment of the lens body includes any one or more of texturing, frosting, electroplating, or reflective paper back glue.

[0045] Provide a lamp, as Figure 13 shown, including a lamp body 5 and the up-and-down light emitting lens as described above; the up-and-down light emitting lens is installed on the lamp body. The components such as the light source and the circuit board included in the lamp body are prior art and will not be elaborated here.

[0046] The above is the elaboration of the up-and-down light emitting lens and the lamp of the present invention to help understand the present invention; however, the implementation manners of the present invention are not limited by the above embodiments. Any changes, modifications, substitutions, combinations, and simplifications made without departing from the principle of the present invention shall be equivalent replacement manners and are all included in the protection scope of the present invention.
