Optionally, the light-transmitting cover 13 is coated with smoothing powder, so that the light-transmitting cover 13 with smoothing powder performs a second treatment on the emitted light, so that the emitted light is more uniform.

Further, the annular light emitting device further includes a reflective ring 14 disposed between the upper cover body 11 and the light emitting assembly 2 for reflecting the light emitted by the light emitting assembly 2 to the transparent cover 13 . In this embodiment, the light emitted by the light-emitting assembly 2 to the reflective ring 14 is reflected to the light-transmitting cover 13 through the reflective ring 14, and then emitted after being processed by the light-transmitting cover 13, so that the light irradiated by the annular light-emitting device can It is indirectly irradiated through the reflective ring 14, and after being processed by the light-transmitting cover 13 coated with uniform powder, the irradiated light has the advantages of uniform softness and no glare.

In the present disclosure, the light-emitting assembly 2 includes a lamp holder 21 and a plurality of LED light sources 22 arranged on the lamp holder 21; 22 are distributed at the edge of the lamp holder 21 at equal intervals, so that the LED light sources 22 are evenly distributed and form a ring structure. In this embodiment, the LED light source 22 is arranged at the edge of the lamp holder 21, that is, close to the inner side of the light-transmitting cover 13, so as to facilitate the heat dissipation of each LED light source 22, enhance the heat dissipation capability of the LED light source 22 itself, and protect the environment. The heat dissipation inside the ring-shaped light-emitting device and the influence of other components are small, which increases the stability of the ring-shaped light-emitting device; in addition, the LED light source 22 can reduce the comprehensive power consumption of the LED light source 22 close to the inner side of the light-transmitting cover 13, reaching more environmentally friendly requirements. Preferably, the distance between two adjacent LED light sources 22 is 7 mm to 10 mm. Setting it within this range can avoid affecting the luminous effect due to the excessive distance between the LED light sources 22, and can also avoid the distance between the LED light sources 22.
