DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] It should be noted that when an element is referred to as being “connected to” or “disposed on” another element, it can be directly on the other element or indirectly on the other element.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] Please combine Figures 1 to 3The utility model provides a lens 100, comprising: a light-absorbing surface 1 / 2 located on the left and right sides, and an arc-shaped curved surface formed between the two light-absorbing surfaces; the curved surface comprises a number of arc sections realized according to the method of the above-mentioned embodiment, and both the inner and outer side surfaces of the curved surface are light-emitting surfaces 3 / 4. The lens 100 is a full-curved lens, and the thickness of each arc section of the curved surface is different, and the light-emitting angle of each section of the curved surface is different. Specifically, setting the two side surfaces of the lens as light-absorbing surfaces helps to effectively control the light irradiation on the light-absorbing surface 1 / 2, and overcomes the problem of the light being reflected back and forth multiple times between the two surfaces, and finally forming stray light on the irradiation surface. Furthermore, the lens 100 is a waterproof lens with an independent silicone ring, and can be used alone in outdoor scenes. In addition, frosted parts are formed on both sides of the light-emitting surface of the lens 100, so that the lighting effect of the three-sided window frame can be consistent. The lens 100 of the present invention has been minimized and compatible with small light-emitting surface chips for large-angle light emission, further overcoming the reflection on both sides of the lens 100 and avoiding stray light. Traditional window lamps with large-angle lenses will face similar problems. Our solution is to match the lens with the smallest light-emitting surface, minimize the lens size, and weaken the stray light reflected from the side wall of the lens through a special internal structure. Furthermore, the light source adopts a patch light source with a package size of 2016. After the light source is distributed through the lens, the light spot can be distributed with equal width on the top and side surfaces of a window sill with a width of 3m and a height of 4.5m. The overall width of the light spot is between 750-850mm, and its light spot distribution is as follows. Figure 5 shown.

[0033] The lens 100 is set as a full-curved lens, and the light output angle of each arc section thereof is different, so that the product can achieve the function of equal-width light spot.

[0034] Please combine Figures 5 to 8 The utility model is a window lamp, comprising: a fixed frame 01 having an accommodating cavity, a light-emitting module 02 installed in the accommodating cavity and emitting a light spot toward one side of the fixed frame 01; the light-emitting module 02 has a lens 100 as described above, which is covered on each light source.

[0035] In a preferred embodiment, the light-emitting module 02 comprises: a control circuit board 021 mounted within a fixed assembly 020; a plurality of light sources 022 mounted on the control circuit board 021; a lens 100 covering each light source 022; a structural member 023 securing each lens 100 and having a central slot a formed therein for light to pass through; a baffle 024 slidably positioned across the slot a; and a balancing link structure 025 disposed within the fixed assembly 020 and below the control circuit board 021. Specifically, the structural member 023 is provided with engaging rails b1 on either side of the slot a, each rail having a first toothed structure formed thereon; and the baffle 024 is provided with a second toothed structure formed on either side of the toothed structure for interaction with the toothed structure. The shape of the slot a matches the curved surface of the lens 100. Sliding the baffle 024 allows for adjustment of the light output, thereby facilitating adjustment of the uniformity of the light spot. More specifically, the lens 100 includes at least four lenses. In this embodiment, the number of the lenses 100 is four. The left and right lenses 100 respectively control the light spots on the left and right sides of the window. The two middle lenses illuminate the top surface and the upper side, ensuring that the relatively distant top surface is illuminated. The side light is superimposed to fill the low-light area on the upper side. The zoning control further enables this product to have a better light uniformity effect. Furthermore, the balance link structure 025 of this embodiment includes: a first balance bar movably mounted on the bottom plate of the fixed component 020, a second balance bar arranged above the first balance bar and cross-mounted with the first balance bar in an X structure, and a connecting rod that passes through the first balance bar and the second balance bar and is sleeved with an elastic member. This structural setting overcomes the eccentricity problem during unilateral rotation of this product.

[0036] From the above description, it can be seen that a window lamp of this product uses a lens 100 to make this product have the effect of equal-width light spot, and the balancing connecting rod structure 025 is installed in the fixed component 020, so that this product has a better stability effect when in use. In addition, the engaging slide rail b1 is formed on the structural member 023, and the baffle 024 can be slidably engaged with the engaging slide rail b1. The light output control is achieved by moving the baffle 024, so that this product has better light output uniformity and strong versatility.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
