Self-locking trim ring and channel for optic lens
A lamp comprises an optical lens. The lamp further comprises a self-locking trim ring including a plurality of teeth. The self-locking trim ring is disposed over the optical lens. The lamp further comprises a heat sink. The heat sink has an inner chamber wherein the optical lens is disposed in the inner chamber. The heat sink also has an outer chamber disposed radially outwardly from the inner chamber. The outer chamber has a recess that engages the plurality of teeth. The self-locking trim ring secures the optical lens to the heat sink.
1. A lamp comprising:
an optical lens;
a self-locking trim ring including a plurality of teeth, the self-locking trim ring disposed over the optical lens; and
a heat sink including:
an inner chamber, wherein the optical lens is disposed in the inner chamber; and
an outer chamber disposed radially outwardly from the inner chamber, the outer chamber having a recess that engages the plurality of teeth;
wherein the self-locking trim ring secures the optical lens to the heat sink.
2. The apparatus of claim 1 , wherein:
the recess comprises a plurality of cutouts; and
the outer chamber further comprises a groove, wherein the groove receives the plurality of teeth through the cutouts.
3. The apparatus of claim 2 , wherein the self-locking trim ring further comprises a plurality of bosses that align with the plurality of cutouts and prevent the self-locking trim ring from rotating.
4. The apparatus of claim 1 , wherein the optic lens comprises a flange and wherein the inner chamber comprises an inner groove that receives the flange.
5. The apparatus of claim 1 , wherein the inner chamber comprises an inner groove that receives an adhesive.
6. The apparatus of claim 1 , wherein the self-locking trim ring is plastic.
7. The apparatus of claim 1 , wherein the self-locking trim ring is permanently locking.
8. A lamp comprising:
an optical lens;
a self-locking trim ring comprising a plurality of ridges having flanks; and
a lens housing comprising:
an inner channel for supporting the optical lens;
a sealant disposed within the inner channel, the sealant creating a bond between the lens housing and the optical lens;
an outer channel comprising a recess for engaging the flanks of the plurality of ridges; and
a barrier for separating the inner channel and the outer channel, the barrier holding the optic lens in place and preventing the optic lens from shifting within the inner chamber;
wherein the self-locking trim ring secures the optical lens to the lens housing.
9. The lamp of claim 8 , wherein:
the recess comprises a plurality of openings and the outer channel is for receiving the plurality of ridges via the openings.
10. The lamp of claim 9 , wherein the self-locking trim ring further comprises a plurality of protruding guides for aligning with the plurality of openings to prevent the self-locking trim ring from rotating.
11. The lamp of claim 8 , wherein the inner channel is for receiving the optical lens comprising of a flange.
12. The lamp of claim 8 , wherein the self-locking trim ring is synthetic.
13. The lamp of claim 8 , wherein the self-locking trim ring permanently secures the optical lens to the lens housing.
14. A method for securing an optical lens to a heat sink of a lamp, comprising the steps of:
inserting the optical lens into an inner chamber of the heat sink of the lamp;
aligning a plurality of teeth of a self-locking trim ring with a plurality of cutouts of a recess in an outer chamber of the heat sink;
inserting the teeth into a groove in the outer chamber, through the cutouts;
and
rotating the self-locking trim ring to engage the recess with the plurality of teeth.
15. The method of claim 14 , further comprising the step of permanently coupling the recess with the plurality of teeth by rotating the self-locking trim ring until a plurality of bosses of the self-locking trim ring align with the plurality of cutouts to prevent the self-locking trim ring from further rotating.
16. The method of claim 14 , further comprising the step of rotating the self-locking trim ring until a plurality of bosses of the self-locking trim ring align with the plurality of cutouts to prevent the self-locking trim ring from further rotating.
17. The method of claim 14 , further comprising the step of inserting a sealant into a groove of the inner chamber prior to inserting the optical lens into the inner chamber.
18. The method of claim 14 , wherein the step of inserting an optical lens into an inner chamber of a heat sink comprises inserting a flange of the optical lens into a groove of the inner chamber.
19. The method of claim 14 , wherein the step of aligning a plurality of teeth of a self-locking trim ring with a plurality of cutouts of a recess in an outer chamber of the heat sink comprises aligning a trim ring guide mark with a heat sink guide mark.
