Example 1

As shown in fig. 1 and 2, the downlight of the present embodiment includes a face ring 10, a face mask 20, a reflector 30, a housing 40, a seal ring 50, a fastener 60, a circuit board 70, and a mounting bracket 80.

As shown in fig. 2 and 3, the housing 40 is a cylindrical housing, and includes a housing bottom plate 41, a housing open end 42, a housing side wall 43, and a housing flange 44. The housing bottom plate 41 is disposed opposite to the housing opening end 42, the top end of the housing sidewall 43 is vertically connected to the housing bottom plate 41, and the housing flange 44 is disposed at the housing opening end 42, vertically connected to the bottom end of the housing sidewall 43, and protrudes outside the housing 40. The housing sidewall 43 and the housing bottom plate 41 define a cavity. The housing 40 can protect the internal components of the lamp and can also serve as a heat sink to quickly remove heat from the lamp.

The reflector 30 is cylindrical, and the reflector 30 includes a reflector bottom plate 31 and a reflector open end 32 which are disposed opposite to each other. Wherein the reflector bottom plate 31 is located within the cavity of the housing 40 and abuts to the housing bottom plate 41 of the housing 40. The reflector opening 32 end extends from the open end of the housing 40 out of the housing 40 and abuts the top surface of the visor 20. The reflector 30 may also block dust while meeting the need for light collection or scattering.

As shown in fig. 3 and 4, the top of the face ring 10 is connected to the open end of the housing 40, specifically, to the housing flange 44. The cover 20 is a light-transmitting plate, and the edge portion of the cover is clamped by the face ring 10 and the reflector 30, and the cover 20 and the reflector 30 enclose a first sealed cavity 110.

In this embodiment, the face ring 10 includes a first retaining wall 1 having a ring shape, and the face mask 20 includes a first recess 4 having a ring shape. The first retaining wall 1 protrudes out of the top surface of the face ring 10 and is inserted into the first groove 4, and the shape and size of the first retaining wall 1 are consistent with those of the first groove 4. In other embodiments, the annular first groove is recessed in the top surface of the face ring 10, and the annular first retaining wall protrudes from the bottom surface of the face mask 20 and is inserted into the first groove of the face ring 10.

Even if no seal ring is installed in the annular gap 51, the present embodiment can achieve the waterproof rating of IP 44.

As shown in fig. 3, the base 6 protrudes from the top surface of the face ring 10, and the fasteners 60 pass through the housing flange 44, mount to the base 6, and connect the housing 40 to the face ring 10. The housing 40, the reflector 30, the visor 20 and the face ring 10 together enclose a second sealed chamber 120, including the gap between the housing 40 and the reflector 30, including the gap between the reflector 30 and the base 6, etc. The fasteners 60, preferably screws, are threaded into threaded holes in the top surface of the base 6 to integrally connect the housing 40 to the face ring 10.

After the screw is screwed in, the opening end face of the reflector 30 is attached to the top face of the face shield 20, and a certain pressure is maintained, so that the waterproof performance of the joint of the reflector 30 and the face shield 20 is improved, and water vapor is prevented from entering the first sealed cavity 110 from the joint.

After the screws are screwed in, the housing flange 44 is attached to the top surface of the base and a certain pressure is maintained, so that the waterproof performance of the joint of the housing 40 and the face ring 10 is improved, and water vapor is prevented from entering the second sealed cavity 120 from the joint.

In other embodiments, a resilient gasket 61 may be added between the housing flange 44 and the base 6. Under the pressure of the fastener 60, the gasket 61 can further improve the waterproof performance of the joint of the housing 40 and the face ring 10, and prevent water vapor from entering the second seal cavity 120.

A circuit board 70 is disposed in the first sealed cavity, and the circuit board 70 is a circular plate in this embodiment and is mounted to a bottom surface of the bottom plate of the reflector 30 on a side facing the face mask 20. The circuit board 70 includes a light source 71 provided on a bottom surface of the circuit board 70 on a side facing the mask 20. The connector 72 passes through the circuit board 70, the reflector 30 and the housing bottom plate 41 of the housing 40, and one end of the connector is electrically connected to the circuit board 70 and the other end is electrically connected to a power supply (not shown). The connection of the connecting piece 72 to the housing floor 41 is well sealed.

Electronic components such as the circuit board 70, the light source 71 and the like are all installed in a first sealing cavity defined by the inner wall of the reflector and the face cover, a second sealing cavity is defined by the outer wall of the reflector, the inner wall of the shell and the face ring together, and the waterproof effect of the down lamp can be further improved.

A plurality of mounting brackets 80 are uniformly distributed on the outer sidewall of the base 6 of the face ring 10 or the outer sidewall of the housing 40, one end of each mounting bracket 80 is connected to the face ring 10, and the other end thereof extends in a direction away from the outer sidewall of the base 6. The mounting bracket also comprises an elastic sheet, and the included angle between the elastic sheet and the outer side wall of the base 6 is 30-60 degrees. When the installation is carried out, the installation surface such as a ceiling can be clamped between the surface ring 10 and the installation bracket 80 through the installation bracket 80, and the fixation effect is achieved.
