[0031] See also Figures 1 to 3 One embodiment of the present invention provides a downlight, comprising: a housing 10 , a main light source assembly 20 and an indicator light assembly 30 .

[0032] The housing 10 is provided with a light guide cavity 11 and a light guide structure 12. The light guide structure 12 is located on the side of the light guide cavity 11 and outside the light guide cavity 11. The light output side of the housing 10 is provided with a first light output port 13 and a second light output port 14.

Alternatively, in some other optional embodiments, the light guide structure 12 includes a light guide channel 122 connected to the second light outlet 14. The light guide channel 122 is located on the side of the light guide cavity 11 and outside the light guide cavity 11. The indicator light assembly 30 emits light toward the light guide channel 122. The light emitted by the indicator light assembly 30 is guided by the light guide channel 122 and then emitted from the second light outlet 14.

[0034] In this embodiment, the light guide structure 12 includes a light guide column 121 and a light guide channel 122. The light guide channel 122 is located on the side of the light guide cavity 11 and outside the light guide cavity 11. The light guide channel 122 is connected to the second light outlet 14. The light guide column 121 is at least partially installed in the light guide channel 122 and extends toward the second light outlet 14. The indicator light assembly 30 emits light toward the light guide column 121.

[0039] In some optional embodiments, a circuit board 152 is provided in the accommodating cavity 15, and the main light source assembly 20 and the indicator light assembly 30 are both electrically connected to the circuit board 152. The accommodating cavity 15 facilitates the installation of the circuit board 152, and a driving circuit or other suitable circuit structure can be provided on the circuit board 152.

[0040] In some optional embodiments, the indicator light assembly 30 is arranged on a side of the circuit board 152 away from the main light source assembly 20, and the circuit board 152 blocks the light guide cavity 11 and the indicator light assembly 30, thereby further preventing the light emitted by the indicator light assembly 30 from entering the light guide cavity 11.

[0041] The specific structure of the main light source assembly 20 can be appropriately designed according to actual needs. For example, the main light source assembly 20 includes a substrate and a plurality of LED lamp beads arranged on the substrate. The substrate is arranged in the light guide cavity 11, and the LED lamp beads face the first light outlet 13.

[0042] The specific structure of the indicator light assembly 30 can be appropriately designed according to actual needs. For example, the indicator light assembly 30 includes an LED indicator light, which points toward the light guide structure 12. The indicator light can be used to indicate the operating status of the downlight.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
