[0030] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.
[0031] like Figure 1 As shown, a lens that changes its angle by altering the brightness of an LED includes a first convex hull 1 and a second convex hull 2. The first convex hull 1 and the second convex hull 2 are arranged in a row, with the rows of first convex hull 1 and second convex hull 2 spaced apart. The first convex hull 1 and the second convex hull 2 are curved surfaces. The curvature angles of the first convex hull 1 and the second convex hull 2 are 20° and 45°, respectively.
[0032] like Figure 2 and Figure 3As shown, a lamp that changes its angle by altering the brightness of an LED includes a lens, a lamp body assembly 3, a power supply assembly 4, and a bracket 5. The lens is housed within the lens assembly 6, the lamp body assembly 3 is fixedly mounted on the rear side of the lens assembly 6, the power supply assembly 4 is fixedly mounted on the rear side of the lamp body assembly 3, and the bracket 5 is rotatably mounted on the lamp body assembly 3. A light shield 8 is fixedly mounted on the upper front side of the lens assembly 6.
[0033] like Figure 2 As shown, the power supply assembly 4 is equipped with a DIP switch 7, which controls the brightness of the first convex fossa 1 and the second convex fossa 2. In practical applications, customers only need to adjust the LED brightness using the DIP switch on the lamp to achieve different angle changes.
[0034] The lens of this invention adopts a free-form surface design (such as...). Figure 1 (As shown in the curved surface), when the first convex 1 at 20° is illuminated at 80% brightness and the second convex 2 at 45° is illuminated at 20% brightness, the first angle (e.g., 20°, light pattern as shown) is achieved. Figure 4 When the first convex hull 1 (20°) is 50% bright and the second convex hull 2 (45°) is 50% bright, a second angle (e.g., 30°, light pattern as shown) is achieved. Figure 5 When the first convex hull 1 at 20° is bright at 20%, and the second convex hull 2 at 45° is bright at 80%, a third angle (such as 45°, light pattern as follows) is achieved. Figure 6 ).
[0035] The lens structure of this invention differs significantly from the convex hull of other symmetrical angle lens structures. Normal symmetrical angle lens structures have convex hulls of identical diameter; the lens structure of this invention has convex hulls of two different diameters (e.g., ...). Figure 1 The two types of convex hulls have significantly different test angles when tested individually. By mixing the two angles and controlling the current, three or four angle changes can be achieved. This utility model can achieve multiple angle changes with a single lens without replacing the lens, which greatly facilitates customer operation and can meet the lighting needs of different customers and different scenarios. It expands the application range of the product, reduces the number of lenses, saves enterprise development costs, reduces customer inventory costs, and provides convenience for customer inventory.
[0036] The surface angles of the first convex hull 1 and the second convex hull 2 are 10° and 55°, respectively. Other embodiments of this invention can also have surface angles of 30° and 55°. Other structures are consistent with the embodiments.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
