The first housing 20 has a first receiving cavity 21, and the second housing 30 has a second receiving cavity 31. The first housing 20 is partially mounted in the second receiving cavity 31. The second housing 30 has a light exiting opening 32 extending through the second receiving cavity 31. The first receiving cavity 21 is provided with a light emitting unit 22, and the light emitting unit 22 faces the light emitting port 32, so that the light of the light emitting unit 22 is from the second. The light exit port 32 of the housing chamber 31 is emitted.

Specifically, the first receiving cavity 21 has an opening 23 facing the second housing 30 , and the light emitting unit 22 faces the opening 23 . The second receiving cavity 31 extends through the second housing 30 and has a pair of interfaces 33 opposite to the light exit opening 32. The pair of interfaces 33 are in contact with the first receiving cavity 21, and the light emitted by the light emitting unit 22 passes through the first housing 20 in sequence. The opening 23 and the second receiving cavity 31 are then emitted from the light exit port 32. Since the second housing 30 is rotatable in the mounting ring 10 and the second housing 30 is coupled to the first housing 20, the first housing 20 follows the second housing 30 when the second housing 30 is rotated. Rotating together; the first housing 20 is swung relative to the second housing 30 for adjusting the swing of the light-emitting unit 22 by adjusting the first housing 20, adjusting the rotation of the light-emitting unit 22 by adjusting the second housing 30, thereby implementing the light-emitting unit 100 Adjustment of the direction of the light.

The mounting ring 10 is annular, specifically annular, and is sleeved on the outer wall of the second housing 30. A circlip 11 is disposed on the outer wall of the mounting ring 10, and a face ring 12 is formed at one end of the mounting ring 10 toward the light exit opening 32.

In this embodiment, the limiting ribs 37 of the second casing 30 and the limiting ribs of the inner wall of the mounting ring 10 are each such that the angle at which the second casing 30 can rotate is in the range of 0 to 355 degrees. Of course, when the number of the limiting ribs of the two increases, the range of the angle at which the second housing 30 can rotate is reduced. For example, if the two limiting ribs are respectively disposed, the second housing 30 can rotate at an angle. In the range of 0 to 180 degrees.

In order to reduce the light loss, the reflector 40 is provided in the second housing chamber 31. The light exit port of the reflector 40 faces the light exit port 32 of the second casing 30, and the light entrance port of the reflector 40 faces the pair of interfaces 33 of the second casing 30. The outer wall of the reflector 40 is circumferentially formed with a card slot 41. The inner wall of the second receiving cavity 31 is circumferentially provided with a buckle 38, and the buckle 38 is engaged with the card slot 41 to fix the reflector 40 in the second receiving cavity 31. When the second housing 30 needs to be rotated, the user can drive the reflector 40 to rotate, thereby driving the second housing 30 to rotate. Of course, instead of providing the reflector 40, a reflective material may be coated on the inner wall of the second casing 30. It should be noted that, since the user needs to swing the first housing 20 through the second receiving cavity 31, when the reflector 40 is disposed in the second receiving cavity 31, the height of the reflector 40 should not be too high, and the reflector 40 The light entrance port cannot abut on the first housing 20.

As shown in FIG. 3, the first housing 20 is coupled to the second housing chamber 31. The first housing 20 is annular, specifically annular, and the first housing 20 is sized to be partially received in the second receiving cavity 31. In the circumferential direction, the outer wall of the first housing 20 is formed with a pair of convex first guiding portions 24, and the second housing 30 is formed adjacent to the inner wall of the pair of interfaces 33 with a pair of second portions suitable for the first guiding portion 24 to be inserted. The guiding portion 39, the circumferential direction and the bottom of the second guiding portion 39 are provided with a limiting portion, and when the first housing 20 and the second housing 30 are mounted, the guiding and the limiting are realized by the first guiding portion 24 and the second guiding portion 39. .

In this embodiment, the first pivot hole 241 is formed on the first guiding portion 24, the second pivot hole 391 is formed on the second guiding portion 39, and the pivoting shaft is two through the second from the two sides. The pivot hole 391 and the bolt 50 of the first pivot hole 241. Of course, the pivot shaft can also be a screw or other fastener such as a pin. As a variant, a pivot may be provided on the outer wall of the first housing 20, and a pivot hole is provided in the inner wall of the second housing 30, and the pivot is rotatably mounted on the pivot hole, and the first housing 20 is also realized. The pivotal connection of the second housing 30.

The circumferential dimension of the first housing 20 is smaller than the circumferential dimension of the second housing 30, so that the first housing 20 can swing relative to the second housing 30 in the second receiving cavity 31, and the swing angle is at plus or minus twenty. Within the range.

The luminaire provided in this embodiment can adjust the direction of the outgoing light of the luminaire according to the change of the key illumination area. The swinging of the first housing 20 relative to the second housing 30 can be prevented by the set screw 60 when the adjustment of the outgoing light direction of the luminaire is not required. Specifically, the stop screw 60 is detachably passed through the second housing 30 and the first housing 20. Of course, the stop screw 60 does not overlap the pivot.

As shown in FIG. 4, the first receiving cavity 21 further includes an optical element 25 covering the light emitting unit 22. The optical element 25 is an optical lens that is locked in the first receiving cavity 21 . The first receiving cavity 21 further includes a light source plate 26 supporting the light emitting unit 22, and a fixing ring 27 that is snapped into the opening 23 of the first receiving cavity 21. The light emitting unit 22 is an LED.

The luminaire 100 further includes a heat dissipating portion 70 extending from the first housing 20 toward the second housing 30, that is, the heat dissipating portion 70 is integrally formed with the first housing 20. The heat dissipating portion 70 includes a central heat sink 71 aligned with the first housing 20, and a peripheral heat sink 72 surrounding the central heat sink 71. The end of the peripheral heat sink 72 adjacent to the second housing 30 has an outer surface from the outer surface of the central heat sink 71. When the heat sink 72 extends the recess 721 to swing the first housing 20 about the pivot relative to the second housing 30, the second housing 30 can be partially received in the recess 721 without interfering with the peripheral heat sink 72. . The groove 721 is an annular wedge groove, and the groove 721 has a wedge shape in a vertical direction.

The structural features of the luminaire of this embodiment are described above, and the assembly and use of the luminaire are described below.
