AI Technical Summary
In existing lamps, the gap between the radiator and the front ring causes light leakage, affecting the use effect.
A positioning groove is opened on the upper part of the surface ring of the lamp, and a positioning convex edge is formed outside the positioning groove. The inner diameter of the positioning convex edge is greater than the outer diameter of the radiator. The connecting plate of the radiator is locked in the positioning groove through the limiting groove and studs to ensure that the outer edge of the radiator is limited to the inner side of the positioning convex edge.
Through this design, light is effectively prevented from leaking from the gap between the radiator and the surface ring, increasing optical density and improving the use effect.

Technical Field
[0001] The utility model relates to the technical field of lamps, in particular to a lamp without light leakage. Background Art
[0002] Usually, the lamp includes a front ring and a heat sink. The upper part of the existing front ring does not have a groove. Usually, the heat sink is directly locked to the upper end of the front ring against the screw hole. The outer diameter of the upper end of the front ring is consistent with the outer diameter of the heat sink. This causes the internal light to leak from the gap between the heat sink and the front ring, affecting the use effect. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a light leakage-free lamp, including a face ring and a heat sink, the upper portion of the face ring is recessed into a positioning groove, the outer edge of the positioning groove forms a positioning convex edge, the inner diameter of the positioning convex edge is larger than the outer diameter of the radiator, the radiator is buckled in the positioning groove so that the outer edge wall of the radiator is limited to the inner side of the positioning convex edge.
[0004] A further implementation scheme of the utility model is that a plurality of limiting grooves are circumferentially formed on the positioning convex edge.
[0005] A further implementation scheme of the utility model is that a stud is formed on the outer wall of the positioning flange, the stud is integrally formed corresponding to the outer side of the limiting groove, and the upper end surface of the stud is flush with the bottom surface of the limiting groove.
[0006] A further implementation scheme of the utility model is that a boss is formed on the bottom surface of the positioning groove for supporting the bottom edge of the radiator.
[0007] A further implementation scheme of the utility model is that a connection plate is convexly formed on the outer edge of the radiator, and the connection plate passes through the limiting groove and is locked on the stud by screws.
[0008] A further implementation scheme of the utility model is that a reinforcing rib is formed and connected between the boss and the positioning flange.
[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] A positioning groove is provided at the upper end of the front ring, the outer side of the positioning groove is a positioning convex edge, and a limiting groove is provided on the positioning convex edge. The outer diameter of the radiator is smaller than the inner diameter of the positioning convex edge. Therefore, when the connecting plate on the radiator is installed on the stud corresponding to the limiting groove, the outer edge of the radiator is limited to the inner side of the positioning convex edge, thereby achieving better light leakage prevention, increasing light tightness, and improving the use effect.
[0011] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1 and Figure 2The utility model provides a light leakage-free lamp, including a face ring 1 and a heat sink 2. The upper portion of the face ring 1 is recessed into a positioning groove 10, and a positioning convex edge 11 is formed on the outer edge of the positioning groove 10. The inner diameter of the positioning convex edge 11 is larger than the outer diameter of the heat sink 2. The heat sink 2 is buckled in the positioning groove 10, so that the outer edge wall of the heat sink 2 is limited to the inner side of the positioning convex edge 11, that is, the outer edge of the heat sink 2 is sunken in the positioning groove 10, and light sealing is achieved through the positioning convex edge 11, thereby achieving a better anti-light leakage effect.
[0019] In addition, a plurality of limiting grooves 12 are circumferentially formed on the positioning flange 11 , and a stud 13 is formed on the outer wall of the positioning flange 11 . The stud 13 is integrally formed corresponding to the outer side of the limiting groove 12 , and the upper end surface of the stud 13 is flush with the bottom surface of the limiting groove 12 .
[0020] A boss is formed on the bottom surface of the positioning groove 10 for supporting the bottom edge of the heat sink 2 , and a reinforcing rib 14 is formed and connected between the boss and the positioning convex edge 11 .
[0021] In addition, a connecting plate 20 is convexly formed on the outer edge of the radiator 2, and the connecting plate 20 passes through the limiting groove 12 and is locked on the stud 13 by screws. Therefore, when the connecting plate 20 on the radiator 2 is installed on the stud 13 corresponding to the limiting groove 12, the outer edge of the radiator 2 is limited to the inner side of the positioning convex edge 11, thereby achieving better light leakage prevention, increasing light tightness, and improving the use effect.
