The pressing member40is arranged on one side of the light transmitting element30away from the LED light board20. That is part region of the light transmitting element30is closely sandwiched between the pressing member40and the lamp holder10. The pressing member40includes a first end41and a second end42opposite to the first end41. The first end41is hinged with the lamp holder10so that the pressing member40can be turned on or off. The second end42of the pressing member40is buckled with the lamp holder10to fix the light transmitting element30on the lamp holder10. The buckle assembly50is arranged on the second end42of the pressing member40and is used for fixing the pressing member40on the lamp holder10and positioning the light transmitting element assembly30.

That is, a gap is formed between the lamp holder10and the pressing member40, which is used for clamping and positioning the light transmitting element30. What we can describe in other word is that: a lamp holder assembly includes the lamp holder10, the pressing member40and the buckle assembly50, which can be used for clamping an optical component similar to the light transmitting element30.

A first through-hole432is defined on a bottom wall431of the groove cavity43. A second through-hole11is defined on the lamp holder10aligned with the first through-hole432. The hook51is passing through the first through-hole432and the second through-hole11, and fastened to the lamp holder10. A card slot12is defined on a surface of the lamp holder10away from the pressing member40, and an end of the hook51is received in the card slot12to fix the light transmitting element30on the lamp holder10.

Referred toFIGS.5to7, the hook51includes a first hook part512, a limit part513, and a first rotating shaft511threaded at the joint of the first hook part512and the limit part513. The first hook part512and the limit part513are located on two opposite sides of the first rotating shaft511. The first hook part512and the limit part513can be integrally connected. The first hook part512is passing through the first pass hole432and the second pass hole11and is buckled to the lamp holder10. The first rotating shaft511is hinged to the pressing member40so that the hook51can be rotated around the first rotating shaft511. The limit button52includes a second rotating shaft522and a second hook part521.

The first torsion spring53is arranged around the first rotating shaft511, and one end of the first torsion spring53is in contacted with a bottom wall431of the groove cavity43, and the other end of the first torsion spring53is in contacted with the hook51. When the first torsion spring53is compressed, the first hook part512hooks the lamp holder10, and when the first torsion spring53is in an expansion state, the first hook part512is detached from the lamp holder10. The second torsion spring54is arranged around the second rotating shaft522, and one end of the second torsion spring54is also in contacted with the bottom wall431of the groove cavity43, and the other end of the second torsion spring54is in contacted with the limit button52to press the limit part513by the second hook part521of the limit button52. When the second torsion spring54is in a compression state, the second hook part521hooks the limit part513, and under the elastic force of the second torsion spring54, the limit button52presses the limit part513of the hook part51, so as to position the hook part51. When the second torsion spring54is in an expansion state, the second hook part521and the limit part513are detached. This disclosure uses the elasticity of the first torsion spring53and the second torsion spring54to fasten the pressing member40on the lamp holder10, and then position the light transmitting element30, which can realize the manual installation of the light transmitting element30without a screwdriver, this operation is simple and convenient, and the replacement of the light transmitting element30is convenient.

Referred toFIGS.7to9, in this embodiment, the limit part513includes a first guide slope515near to the limit button52, and the hook part521includes a second guide slope523near to and matching with the first guide slope515. By matching the first guide slope515and the second guide slope523, the buckle assembly50is easily fastened.

An accommodating cavity514is defined on the hook51, and the locking member55is rotatably arranged in the accommodating cavity514. A position hole433corresponding to the accommodating cavity514and the locking member55is defined on a side wall of the groove cavity43. If the locking member55is rotated into the limiting hole433, the locking member55is locked (that is, the first torsion spring53is in a locked compression state). Specifically, the locking member55can be rotated to and extended into the limiting hole433. If the limit button52is loosened, a wall of the limiting hole433blocks the locking member55to limit the rotation of the limit part513, so that the first torsion spring53on the locking member55is compressed and cannot be loosened, then the locking member55is locked (that is, the first torsion spring53is in a locked compression state) to maintain the hook51buckled to the lamp holder10. When the locking member55moves out of the limiting hole433, and the limit button52is loosened, the locking member55can release the locking of the compression state of the first torsion spring53, then the locking member55is unlocked (that is, the first torsion spring53is in an unlocked compression state).
