These and other directional terms should not be construed as limiting terms.

As shown in fig. 1, 2 and 4, a multi-scene application lighting fixture 100 includes a housing 1, a light source assembly 2, a light transmissive cover 3 and a light shielding accessory 4.

The housing 1 has a top wall 11, a peripheral side wall 12, and a housing space 13 defined by the top wall 11 and the peripheral side wall 12, and the bottom of the housing 1 has a light outlet 14. The light source assembly 2 is disposed in the accommodating space 13. The light source assembly 2 comprises a light source plate 21, a plurality of light emitting elements 22 integrally arranged on the light source plate 21, wherein the light emitting elements 22 may be LED beads. The light source plate 21 is attached to the top wall 11 of the housing 1 by means of a first screw 23. Of course, in other embodiments, the connection between the light source board 21 and the housing 1 is not limited to the screw connection, but may be other detachable or non-detachable connection, such as snap connection, adhesive connection, or riveting. The top wall 11 is provided with a driving power supply 7 electrically connected with the light source assembly 2. Specifically, the driving power supply 7 is electrically connected to the light source assembly 2 through the cable 71 passing through the housing 1. The light-transmitting cover 3 is attached to the bottom of the housing 1 and closes the light outlet 14.

The bottom of the housing 1 is detachably connected with a face ring 6, and the face ring 6 and the housing 1 jointly clamp the light-transmitting cover 3 therebetween. Specifically, the face ring 6 is attached to the bottom of the housing 1 by a second screw 61. Of course, in other embodiments, the connection relationship between the face ring 6 and the housing 1 is not limited to screw connection, but may be other detachable or non-detachable connection, such as snap connection, adhesive connection, riveting, etc. In order to prevent mosquitoes from entering the multi-scene application lighting lamp through the gap between the light-transmitting cover 3 and the shell 1, a sealing ring 5 is arranged at the joint of the light-transmitting cover 3 and the shell 1. Specifically, the bottom edge of the housing 1 is provided with a ring of engaging groove 16, and the seal ring 5 is engaged in the engaging groove 16 and has a portion protruding out of the engaging groove 16.

The whole shell 1 is formed by die casting an aluminum alloy material. A plurality of heat dissipation parts 15 formed integrally with the housing 1 are uniformly provided on the outer side of the peripheral side wall 12 of the housing 1, the inside of each heat dissipation part 15 is hollow, and each heat dissipation part 15 is provided with a heat dissipation hole 151 and a heat dissipation port 152 communicating with the inside thereof. The heat dissipation port 152 penetrates the heat dissipation portion 15 in the up-down direction. In this structure of the plurality of hollow heat dissipation parts 15 circumferentially arranged, when heat is dissipated, the heat generated by the light source assembly 2 is transferred to the housing 1 and transferred to the external environment, the external air enters and exits the inside of the heat dissipation parts 15 through the heat dissipation holes 151 and the heat dissipation openings 152, and the external air flows through the heat dissipation openings 152 of the heat dissipation parts 15 to form convection in the vertical direction, so that the heat is exchanged with the housing 1 in a convection manner, and a good heat dissipation effect is achieved. The convection heat dissipation of the heat in the multi-scene application lighting lamp 100 to the periphery can be realized, the heat dissipation effect is improved, and the multi-scene application lighting lamp is suitable for a light source assembly with higher power. In this embodiment, the heat dissipation portion 15 has a prismatic structure, however, in other embodiments, the specific structure of the heat dissipation portion 15 may have other shapes, which is not limited herein. The heat dissipation port 152 may be provided alone, and the heat dissipation hole 151 may be omitted. In addition, in order to facilitate assembly of the face ring 6 with the housing 1, a connection between the face ring 6 and the housing 1 may be provided on the heat radiating portion 15.

As shown in connection with fig. 1, 4 and 7, the shade attachment 4 comprises a plurality of replaceable, differently shaped shade shields 41, the shade attachment 4 being configured to: any one of the plurality of light shields 41 is detachably attached to the outside of the light shield 3 alone and can shield part of the light shield 3 so that a portion of the light shield 3 that is not shielded forms a light emitting region complementary to the shape of the light shield 41. Specifically, the light-transmitting cover 3 and the light-shielding accessory 4 are both plate-shaped structures. The shade attachment 4 includes three shades 41, the three shades 41 having the shape of a 1/4 crescent, a half moon and a 3/4 crescent, respectively. When the light shield 41 of a different shape is replaced, the light shield 41 may be attached to the face ring 6 by a third screw 42. Of course, in other embodiments, the connection between the light shield 41 and the housing 1 may be other detachable connection methods, such as a snap connection.

As shown in fig. 1 to 3, when the 1/4 crescent-shaped light shield 41 is used, the area of the light emergent region formed by the non-shielded part of the light-transmitting cover 3 is larger, and the light-transmitting cover can be applied to darker scenes.

As shown in fig. 4 to 6, when the half-moon-shaped light shield 41 is used, the area of the light-emitting area formed by the non-shielded part of the light-transmitting cover 3 is moderate, and the light-emitting opening 14 is half-shielded, so that the half-moon-shaped light shield can be applied to a scene with moderate brightness.

As shown in fig. 7 to 9, when the 3/4 crescent-shaped light shield 41 is used, the area of the light-emitting area formed by the non-shielded part of the light-transmitting cover 3 is smaller, and the light-emitting area can be applied to brighter scenes. Therefore, different light shields 41 can be used alternatively in different atmosphere scenes, and the light emitted by the light source assembly 2 is emitted from only one side of the light emitting port 14, so that the light emitting effect is better.

Of course, in other embodiments, in order to realize that the light shielding accessory 4 can selectively shield the light-transmitting cover 3, so as to adjust the light emitting area of the light emitting opening 14, so that the lighting fixture can be suitable for different application scenes and atmospheres. The shade attachment 4 is not limited to the above-described structure in which the shade 41 of different shapes is replaced independently, but may be a shade member of other structures, for example, a foldable shade sheet mounted on the outer side of the light-transmitting cover 3, and the size of the light-emitting area of the light-emitting opening is adjusted by folding and unfolding the shade sheet. The specific structure of the shade attachment 4 is not limited by the illustration only.

The technical scope of the present application is not limited to the above description, and those skilled in the art may make various changes and modifications to the above-described embodiments without departing from the technical spirit of the present application, and these changes and modifications should all fall within the scope of protection of the present application.
