Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] This utility model relates to a combined lens, including a lens body 100.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the lens body 100 has a flat plate structure, and its shape can be, but is not limited to, circular, rectangular, or elliptical. The lens body 100 can be made of plastic lens materials such as polycarbonate, acrylic, or polymethyl methacrylate. The lens body 100 has an incident side 101 and an exit side 102. In the illustrated direction, the lower side of the lens body 100 is the incident side 101, and the upper side is the exit side 102. The surface of the incident side 101 (lower side) of the lens body 100 is a Fresnel surface 200, and the surface of the exit side 102 (upper side) of the lens body 100 is a corrugated surface 300. The Fresnel surface 200 and the corrugated surface 300 are integrally formed on the lens body 100, which can be integral injection molding. After molding, the relative positions of the Fresnel surface 200 and the wavy surface 300 remain fixed, and they can be directly installed in different lighting scenarios without causing problems such as incorrect light guiding direction or deviation due to misassembly during the assembly process or equipment vibration during use.

[0032] In some specific embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the wavy surface 300 includes a plurality of first protrusions 310. The first protrusions 310 protrude in the thickness direction of the lens body 100 in a direction away from the incident side 101. In the illustrated direction, each first protrusion 310 protrudes upward on the exit side 102 of the lens body 100. The first protrusions 310 extend in a straight strip along the front-back direction on the exit side 102, and the first protrusions 310 are parallel to each other and arranged adjacent to each other from left to right. Adjacent first protrusions 310 share the same long side. The cross-section of the first protrusion 310 in the thickness direction of the lens body 100 is semi-circular or chamfered, thereby enabling the first protrusions 310 to collectively form a wavy surface.

[0033] In some specific embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the Fresnel surface 200 includes a plurality of second protrusions 210. The second protrusions 210 protrude in the thickness direction of the lens body 100 in a direction away from the exit side 102. In the illustrated direction, the second protrusions 210 all protrude downwards on the incident side 101 of the lens body 100. Each second protrusion 210 is concentrically arranged in a ring around the center of the lens body 100. The cross-section of the second protrusion 210 in the thickness direction of the lens body 100 is serrated. Between two adjacent protrusions, the angle of the serrated end (lower end) of the cross-section of the second protrusion 210 located in the outer ring is smaller than the angle of the serrated end (lower end) of the cross-section of the second protrusion 210 located in the inner ring. Preferably, the angle of the serrated end of the cross-section of the second protrusion 210 is at least 45° and at most 89°.

[0034] This utility model also relates to a lamp that uses the above-mentioned combined lens. For example... Figure 4 , Figure 5 and Figure 6 As shown, the luminaire also includes a lamp holder 400 and a lamp source component 500. The lamp source component 500 and the combined lens are mounted on the lamp holder 400, with the lamp source component 500 facing the incident side 101. Figure 8 As shown, the light generated by the lamp source shines outward through the Fresnel surface 200 and the corrugated surface 300 in sequence, forming a diffused light spot. If the lamp source component 500 produces light of different colors, the light spot will display rainbow colors. The relative positions between the Fresnel surface 200 and the corrugated surface 300 remain unchanged. When installed on the lamp fixture, there is no need to separately position and lock the Fresnel surface 200 and the corrugated surface 300, simplifying the assembly process and improving assembly efficiency.

[0035] In some specific embodiments of this utility model, the lamp source component 500 includes a lamp plate 510 and a plurality of focusing lenses 521. The lamp plate 510 is provided with a plurality of lamp beads 511. Each lamp bead 511 and each focusing lens 521 is aligned one-to-one, i.e., one lamp bead 511 is opposite to one focusing lens 521. Each focusing lens 521 can be mounted in the lamp holder 400 via a bracket, or it can be directly fixed to the lamp plate. Each lamp bead 511 can be set to a different light color. The lamp bead 511 illuminates the corresponding focusing lens 521, and the focusing lens 521 converges the light generated by the lamp bead 511 before projecting it onto the incident side 101. Alternatively, the plurality of focusing lenses 521 can be disposed on a focusing plate 520. The focusing lenses 521 can be integrally formed on the focusing plate 520, or multiple mounting positions can be provided on the focusing plate 520, with each focusing lens 521 mounted on its respective mounting position. Each focusing lens 521 can be arranged in a rectangular array on the focusing plate 520. Preferably, the focusing angle of the focusing lens 521 is in the range of 6° to 10°, and can be 6°, 6.5°, 7°, 7.5°, 8°, 8.5°, 9°, 9.6°, 10°, etc.

[0036] Furthermore, a mounting cavity 410 is defined within the lamp holder 400. One end of the mounting cavity 410 is open to form a projection port 411. In the illustrated direction, the projection port 411 of the mounting cavity 410 faces upward. The lamp source 500 is mounted in the mounting cavity 410. A combined lens is mounted at the projection port 411. The circumferential sidewalls of the mounting cavity 410 surround the lamp source 500, and light is transmitted outward only from the combined lens.
