As can be seen from the above description, in the light fixture disclosed in the embodiment of the present invention, the housing 100 is provided with the first connecting portion 120 around at least a part of the edge of the opening, the functional component 500 has the second connecting portion 511, the first connecting portion 120 can be connected to the mounting surface ring 300 through the fastener 400, and the second connecting portion 511 is pressed and fixed on the mounting surface ring 300, so as to implement the installation of the functional component 500.

Compared with the prior art, the embodiment of the utility model discloses a lamps and lanterns need not process buckle structure on casing 100 and functional component 500, have undoubtedly promoted the production efficiency of lamps and lanterns, have also simplified the matched stack process of lamps and lanterns simultaneously.

It should be noted that, in this embodiment, the lamp may be of various types, such as a down lamp, a candle lamp, a panel lamp, etc., and this embodiment does not limit the specific type of the lamp.

When the functional block 500 has a light distribution function, the functional block 500 can adjust the illumination characteristics of the lamp, such as illumination, brightness, luminous flux, and light exit angle.

In an alternative scheme, the functional assembly 500 may include a first light distribution element 510, the first light distribution element 510 has a second connection portion 511, and light emitted from the light source module 200 passes through the first light distribution element 510 and then exits from the light exit 310.

Specifically, since the second connection portion 511 is provided on the first light distribution element 510, the first light distribution element 510 is mounted and fixed when the second connection portion 511 is clamped and fixed between the first connection portion 120 and the mounting ring 300. The light emitted from the light source module 200 can be distributed through the first light distribution element 510, and the illumination characteristic of the lamp can be changed through the first light distribution element 510.

In this embodiment, the type of the first light distribution element 510 can be various, as shown in fig. 1 to 3, the first light distribution element 510 can be selected as a light diffusion plate, and after the light is emitted by the light diffusion plate in a light distribution manner, the illumination coverage area of the lamp can be significantly increased; as shown in fig. 8 to 10, the first light distribution element 510 can be selected as a lens element with a converging configuration, and after light is emitted by light distribution of the light diffusion plate, the emitted light of the lamp is more concentrated, and the light intensity and brightness of the lamp are significantly improved.

In order to further optimize the illumination characteristic of the lamp, in an optional scheme, the functional assembly 500 may further include a second light distribution element 520, the first light distribution element 510 is disposed adjacent to the light source module 200, the second light distribution element 520 is disposed on a side of the first light distribution element 510 away from the light source module 200, the second light distribution element 520 is fixedly fitted to the first connection portion 120, and light emitted by the light source module 200 sequentially passes through the first light distribution element 510 and the second light distribution element 520 and then is emitted from the light outlet 310.

It should be understood that, since the first light distribution element 510 has been clamped and fixed between the first connecting portion 120 and the mounting face ring 300 by the second connecting portion 511, that is, the first light distribution element 510 has been mounted and fixed; in this case, the second light distribution element 520 is fixedly fitted to the first connector 120, and then the functional module 500 is mounted and fixed. In a specific working process, the light emitted from the light source module 200 may first pass through the first light distribution element 510 to perform a first light distribution process, and then pass through the second light distribution element 520 to perform a second light distribution process. Based on the embodiment, the lamp comprises two light distribution structures, so that the light distribution precision and the light distribution diversity of the lamp can be improved undoubtedly.

In the present embodiment, the type of the second light distribution element 520 may be various, for example, the second light distribution element 520 may be selected as a light diffusion plate, a lens element, and the like, and the present embodiment is not limited to the specific type thereof. In a specific embodiment, as shown in fig. 11 to 13, the second light distribution element 520 may be a reflector cup, and the reflector cup can collect light emitted from the light source module 200, so that the light emitted from the lamp is more concentrated.

Under the general condition, under the condition that the second light distribution element 520 is a reflector cup, the first light distribution element 510 is a lens element with a convergence configuration, and thus, under the arrangement, light emitted by the light source module 200 can be firstly converged through the lens element for the first time, and then projected into the reflector cup for convergence for the second time after being processed, emergent light after being converged twice has higher concentration degree undoubtedly, and the illumination intensity and brightness are remarkably improved.

In the above embodiments, the horizontal cross-section of the reflector cup may be of circular configuration; in another specific embodiment, as shown in fig. 14 to 16, the second light distribution element 520 is also a reflector cup, and the horizontal cross section of the reflector cup is a square (square or rectangular) configuration. Of course, in the case where the first light distribution element 510 and the second light distribution element 520 are reflector cups, the present embodiment does not limit the specific configuration of the reflector cups.

In the case that the second light distribution element 520 is a reflector cup, since the reflector cup occupies a large space in the height direction, the first receiving space 110 is difficult to receive the reflector cup, and based on this, in an alternative scheme, the mounting surface ring 300 may be formed with a second receiving space 320 in the height direction, the light outlet 310 is communicated with the second receiving space 320, and the second light distribution element 520 partially extends into the second receiving space 320.

Specifically, the mounting surface ring 300 can accommodate the second light distribution element 520 through the second accommodating space 320, so that the second light distribution element 520 can be completely accommodated inside the lamp, so that the second light distribution element 520 is not exposed, the second light distribution element 520 can be prevented from being damaged, and the second light distribution element 520 can be ensured to provide a stable light distribution effect. In general, when the light emitting direction of the second light distribution element 520 directly faces the light outlet 310, the light is distributed by the second light distribution element 520 and then emitted from the light outlet 310.

As described above, the second light distribution element 520 is fixedly engaged with the first connection portion 120, but the embodiment does not limit the specific fixing engagement manner of the second light distribution element 520 and the first connection portion 120, for example, a connection portion may be provided on the second light distribution element 520, and the second light distribution element 520 passes through the mounting surface ring 300 through the connection portion to be fixedly engaged with the first connection portion 120; of course, the second light distribution element 520 may be connected to the first connection portion 120 in various ways, for example, the second light distribution element 520 may be connected to the first connection portion 120 by snapping, adhering, or the like.

In another specific embodiment, the second light distribution element 520 may be provided with a mounting hole 521, and the fastener 400 may pass through the mounting ring 300 to be coupled to the mounting hole 521.

It should be understood that the installation position of the installation hole 521 in the second light distribution element 520 should correspond to the installation position of the fastener 400, so that after the fastener 400 connects the first connection portion 120 and the mounting surface ring 300, the fastener 400 can continue to pass through the mounting surface ring 300 and extend into the installation hole 521 for realizing the matching, thereby realizing the fixed matching relationship between the second light distribution element 520 and the first connection portion 120, so that the second light distribution element 520 can be installed and fixed inside the lamp.

Under such a configuration, only one fastener 400 is used to connect the housing 100 and the mounting surface ring 300, mount and fix the first light distribution element 510, and mount and fix the second light distribution element 520, which undoubtedly reduces the number of connectors, reduces the cost, and optimizes the internal structural layout of the lamp.

In another specific embodiment that the functional assembly includes the first light distribution element 510, the functional assembly 500 may further include a third light distribution element 530, the third light distribution element 530 is disposed adjacent to the light source module 200, the first light distribution element 510 is disposed on a side of the third light distribution element 530 away from the light source module 200, the third light distribution element 530 is mounted on the first light distribution element 510, and light emitted by the light source module 200 sequentially passes through the third light distribution element 530 and the first light distribution element 510 and then is emitted from the light outlet 310.

It should be understood that, as described above, since the first light distribution element 510 has been clamped and fixed between the first connecting portion 120 and the mounting face ring 300 by the second connecting portion 511, that is, the first light distribution element 510 has been mounted and fixed; in this case, the third light distribution element 530 is directly mounted on the first light distribution element 510, and thus the mounting and fixing inside the lamp is completed. In a specific working process, the light emitted from the light source module 200 may first pass through the third light distribution element 530 to perform a first light distribution process, and then pass through the first light distribution element 510 to perform a second light distribution process.

Likewise, the present embodiment does not limit the specific type of the third light distribution element 530. In a specific embodiment, as shown in fig. 17 to 19, the third light distribution element 530 may be a lens element with a converging configuration, the first light distribution element may be a reflector cup, and the light emitted from the light source module 200 may be converged twice in sequence.

More specifically, the third light distribution element 530 may be a component of a tir (total Internal reflection) lens and a polarized lens, the first light distribution element 510 may be a wall-wash reflector, and a polarization direction of the third light distribution element 530 matches with a light emitting direction of the first light distribution element 510. Under the arrangement, the emergent light of the lamp is intensively deflected towards the preset direction, so that the requirement of the irradiation angle of the lamp is met.

In this embodiment, the specific shape of the first connection portion 120 and the second connection portion 511 is not limited, for example, the first connection portion 120 may be a first protruding edge disposed on the edge of the casing 100, the second connection portion 511 may be a second protruding edge, and the first protruding edge and the second protruding edge are disposed correspondingly in the height direction, so that the first protruding edge can press and fix the second protruding edge on the mounting surface ring 300.

In another specific embodiment, the first connecting portion 120 may be circumferentially disposed along the opening, and the second connecting portion 511 may be circumferentially disposed along the first light distribution element 510. It should be understood that, with this configuration, when the second connection portion 511 is clamped and fixed between the first connection portion 120 and the mounting surface ring 300, the first connection portion 120 may be tightly attached to the second connection portion 511 along the circumferential direction, and the second connection portion 511 may also be tightly attached to the mounting surface ring 300 along the circumferential direction, so that there is a large contact area between the first connection portion 120 and the second connection portion 511, and between the second connection portion 511 and the mounting surface ring 300, which undoubtedly improves the mounting stability and reliability therebetween.

In this embodiment, the first connecting portion 120 may be disposed in various ways, for example, the first connecting portion 120 may extend toward the first receiving space 110, but the disposing way may interfere with the internal components of the lamp.

Based on this, in order to avoid the interference of the first connection portion 120 to the internal components of the lamp in the first receiving space 110, in an alternative scheme, the first connection portion 120 may be extended and disposed in a direction away from the first receiving space 110. Specifically, with such an arrangement, the first connecting portion 120 is disposed outside the housing 100, and the functional element 500 is located in the first receiving space 110, so that the first connecting portion 120 does not interfere with the arrangement of the internal components of the lamp.
