Technical Field

[0001] This utility model patent relates to the technical field of square spot lenses, specifically to square spot lenses and square spot lamps. Background Technology

[0002] Lenses are optical systems used to change the light field distribution of LEDs. They are generally composed of transmissive and / or reflective lenses. When the light from an LED passes through a transmissive lens, it is refracted and focused. When the light from an LED passes through a reflective lens, it is reflected and focused, thereby enhancing the light utilization efficiency and luminous efficiency.

[0003] Currently, the light spots formed by lenses are mostly hill-shaped. For different lighting locations or targets, square light spots provide better lighting effects. For example, the prior patent with authorization announcement number CN210462888U discloses an LED lens that forms a uniform square light spot, including an LED light source and a lens body disposed in front of the LED light source. The lens body is composed of a total internal reflection lens and a micro array lens. The total internal reflection lens is located between the micro array lens and the LED light source, and the total internal reflection lens and the micro array lens are fixedly connected. The incident surface of the micro array lens is a plane, and the exit surface of the micro array lens is formed by several free-form surfaces arranged at equal amplitudes and distances.

[0004] In the existing technology, the uniformity of the square light spot formed by the light source projected by the lens is insufficient, and dark areas are prone to appear, resulting in poor lighting effect of the square light spot. Utility Model Content

The light-emitting surface is used to receive light transmitted or refracted by the light-transmitting surface, and the light-emitting surface is used to transmit or refract light to the large reflective area and the small reflective area. The large reflective area and the small reflective area are arranged in a closed and connected manner around the light-emitting surface, and the large reflective area and the small reflective area project light outward to form a square light spot.

[0021] Reference Figure 1-9 The image shown is a preferred embodiment of the present invention.

[0022] A square light spot lens includes a lens body 1, which includes a light-transmitting part 11 and a reflective part 13. A light source projects light onto the light-transmitting part 11, which transmits or refracts light to the reflective part 13. The reflective part 13 reflects light to form a square light spot. The light-transmitting part 11 has a light-transmitting surface, which is arranged in an arched arc shape along the direction towards the light source. The cross-section of the light-transmitting surface tends to be elliptical or elliptical. The light-transmitting surface includes a wide light area 112 and a narrow light area 111. The wide light area 112 is used for light transmission or refraction to form a wide light area, and the narrow light area 111 is used for light transmission or refraction to form a narrow light area.

[0023] In the aforementioned square spot lens, when in use, the light emitted by the light source 2 passes through the light-transmitting part 11, and then the light is transmitted or refracted by the light-transmitting part 11 to the reflective part 13, where it is reflected by the reflective part 13 to form a square spot. Since the light-transmitting surface tends to be elliptical or arranged in an elliptical shape, the light source 2 forms an elliptical spot when passing through the light-transmitting surface. At the same time, it is transmitted or refracted through the wide light area 112 and the narrow light area 111 respectively to form an anisotropic elliptical spot, which is then reflected by the reflective part 13 to form a square spot. In this way, the projected spot is easy to control and there are no dark areas. The square spot is formed more uniformly, and the square spot projection lighting effect is better.

[0024] Square light spots can be either square or rectangular, and can be adjusted to meet the lighting needs of different scenarios.

[0025] The wide light area 112 and the narrow light area 111 are arranged in a curved shape to facilitate the reception of light and reduce light loss.

[0026] Furthermore, the wide and narrow light areas are arranged in a curved shape, and the wide and narrow light areas are used for polarization. The wide light area forms a wide entrance angle, and the narrow light area forms a narrow entrance angle. The wide entrance angle is used to allow light to be transmitted or refracted to form a wide range of light areas, and the narrow entrance angle is used to allow light to be transmitted or refracted to form a narrow range of light areas; this facilitates the formation of square light spots.

[0027] The wide beam area 112 causes the light spot to increase horizontally, making it easier to form a square light spot. Example

[0028] The wide beam area 112 is provided with a first sawtooth surface, and the narrow beam area 111 is provided with a second sawtooth surface. The first sawtooth surface and the second sawtooth surface are arranged in a butt joint manner. The first sawtooth surface and the second sawtooth surface are used to make the light spot more square.

[0029] In this way, the light is processed by the first and second sawtooth surfaces, such as by diffusing or changing the light, thus playing a corrective role and facilitating the formation of square light spots.

[0030] The reflective part 13 includes a large reflective area 132 and a small reflective area 131. The light-transmitting part 11 has a light-emitting surface 14, which is used to receive light transmitted or refracted by the light-transmitting surface. The light-emitting surface 14 is also used to transmit or refract light to the large reflective area 132 and the small reflective area 131. The large reflective area 132 and the small reflective area 131 are arranged in a closed and connected manner around the light-emitting surface 14. The large reflective area 132 and the small reflective area 131 project light outward to form a square light spot.

[0031] With the combined action of the large reflection area 132 and the small reflection area 131, the light rays projected or reflected by the light-emitting surface 14 reach the large reflection area 132 and the small reflection area 131, and are then reflected by the large reflection area 132 and the small reflection area 131 to form a square light spot.

[0032] The light transmitted or refracted by the wide light area 112 passes through the light-emitting surface 14 to the large reflection area 132. The large reflection area 132 is provided with a first microstructure, which is arranged in an array and laid flat in the large reflection area 132. The light transmitted or refracted by the narrow light area 111 passes through the light-emitting surface 14 to the small reflection area 131. The small reflection area 131 is provided with a second microstructure, which is arranged in an array and laid flat in the small reflection area 131. The first microstructure and the second microstructure are used to make the light spot more square; thus, it is convenient to form a square light spot.

[0033] The first microstructure includes multiple first microfacets, which are arranged in a curved shape and have polygonal cross-sections. Each first microfacet is arranged in an array to cover a large reflective area 132. The second microstructure includes multiple second microfacets, which are arranged in a curved shape and extend in a long strip. Each second microfacet is arranged in an array to cover a small reflective area 131.

[0034] The combination of each first microfacet can diffuse the light, making the light spot appear square. The combination of each second microfacet can diffuse the light, making the light spot appear square.

[0035] The light-transmitting part 11 includes a light-shielding surface 12, which is arranged in an enclosing manner to form a light-entry cavity. The light-entry cavity is arranged correspondingly to the light source. The end of the light-shielding surface 12 is arranged to be joined with the light-transmitting surface. The light-shielding surface 12 is used to reflect light to the light-transmitting surface and to prevent light from leaking to the outside of the lens body 1.

[0036] This reduces light loss and effectively improves light utilization, enhances light efficiency, and improves the projection effect of the square light spot. Example

[0037] The reflective part 13 includes a large reflective area 132 and a small reflective area 131. The light-transmitting part 11 has a light-emitting surface 14, which is used to receive light transmitted or refracted by the light-transmitting surface and to transmit or refract light to the large reflective area 132 and the small reflective area 131. The large reflective area 132 and the small reflective area 131 are arranged in a closed and connected manner around the light-emitting surface 14. The dimming surface 15 is simultaneously covered with the large reflective area 132, the small reflective area 131 and the light-emitting surface 14.

[0038] With the combined action of the large reflection area 132 and the small reflection area 131, the light rays projected or reflected by the light-emitting surface 14 reach the large reflection area 132 and the small reflection area 131, and are then reflected by the large reflection area 132 and the small reflection area 131 to form a square light spot.

[0039] Lighting fixture examples: A square spot lamp includes a lens body 1, a light source 2, and a lamp body 3. The lamp body 3 includes a lamp tube 31. The light source 2 and the lens body 1 are respectively installed on the lamp tube 31, and the lamp tube 31 is arranged at an angle.

[0040] In this way, by assembling the lens body 1 and the light source 2 to the lamp body 3, and then assembling the lamp body 3 to the wall and cabinet, the light is projected onto the target object through the lamp tube 31 to form a square light spot.

[0041] It includes multiple lamp bodies 3, multiple light source components 2 and multiple lens bodies 1. Each lamp body 3, each light source component 2 and each lens body 1 is assembled and arranged one by one. Each lamp body 3 is arranged in sequence, and the square light spots formed by each lens body 1 are arranged in sequence and connected.

[0042] In this way, by cooperating with multiple lamp bodies 3, multiple square light spots can be spliced ​​together in the horizontal direction to meet different applications.

[0043] The principle of square light spot formation: The light-transmitting surface is arranged in an elliptical shape. When light passes through the light-transmitting surface, it forms an elliptical light spot. With the help of the wide light area 112 and the narrow light area 111, the elliptical light spot gradually tends to become square, forming an irregular elliptical light spot. Then, with the help of the microstructure of the reflective part 13 to reflect the light, a square light spot is formed.

[0044] Furthermore, by arranging the lamp tube 31 at an angle, the formation of the light spot has a distinction between the near beam area and the far beam area. The microstructure of the reflector 13, in conjunction with the reflected light, forms a trapezoidal light spot. Then, by adjusting the near beam area and the far beam area, the trapezoidal light spot is projected into a square light spot.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
