Detailed Embodiments

[0020] Referring to FIG. 1, which is a schematic stereostructure diagram of a luminaire according to an embodiment of the present disclosure, the luminaire includes a lampshade 10, a heat sink 20, and a light source assembly 30.

[0021] The lampshade 10 and the heat sink 20 are both of a cylindrical structure, and the heat sink 20 is arranged inside the lampshade 10.

[0022] The light source assembly 30 includes a soft substrate 310 and LED light sources 320, the LED light sources 320 are arranged on the soft substrate 310, one surface, facing away from the LED light sources 320, of the soft substrate 310 is attached to an outer wall of the heat sink 20 and is wrapped around the outer wall of the heat sink 20, and the LED light sources 320 are separated from an inner wall of the lampshade 10 by a threshold distance.

[0023] Specifically, the lampshade 10 includes, but is not limited to, a milk-white shade or a striped shade, is made of a material which includes, but is not limited to, a PVC material, a PC material, a glass material, an acrylic material, etc., and is typically in a cylindrical shape, but may also be of a hollow prism structure, and it is only emphasized here that the lampshade 10 has a cylindrical appearance, and the heat sink 20 is arranged in a hollow structure of the lampshade 10 of a cylindrical structure.

[0024] The light source assembly 30 is arranged between the lampshade 10 and the heat sink 20. Specifically, the soft substrate 310 is arranged on an outer surface of the heat sink 20. The soft substrate 310 here includes, but is not limited to, a flexible PCB board. One surface of the soft substrate 310 is attached to the outer wall of the heat sink 20. A specific connection manner includes, but is not limited to, fixed connection with the outer wall of the heat sink 20 via plastic rivets. The other surface of the soft substrate 310 is used for arranging the LED light sources 320 to allow the LED light sources 320 to form a light-emitting surface on the surface, facing away from the heat sink 20, of the soft substrate 310. The soft substrate 310 is wrapped around the outer wall of the heat sink 20, so that the light source assembly 30 forms a light-emitting bar on a periphery of the heat sink 20, the luminaire forms a light source bar capable of emitting light at 360 degrees. Accordingly, the illumination angle of the luminaire is increased, and the luminaire is adapted to the requirements of large illumination places for a larger illumination angle.

[0025] In addition, the LED light sources 320 are separated from the inner wall of the lampshade 10 by a threshold distance, which makes the light transmitted from the lampshade 10 softer, and at the same time, facilitates air circulation so as to effectively dissipate heat from the LED light sources 320. The service life of the LED light sources 320 is improved accordingly. Furthermore, the heat sink 20 is also of a hollow cylindrical structure, which facilitates the formation of a passage for air circulation in the heat sink 20, facilitates the formation of passages for air circulation at inner and outer sides of a laminated structure formed by the heat sink 20 and the LED light sources 320, improves the heat dissipation performance of the heat sink 20, enables the heat sink 20 to effectively dissipate heat from the light source assembly 30, and effectively prolongs the service life of the light source assembly 30.

[0026] Further, referring to FIG. 2, in other preferred embodiments of the present disclosure, a plurality of rows of LED light sources 320 are arranged on the soft substrate 310 on the periphery of the heat sink 20 along a length direction of the heat sink 20, and the LED light sources 320 in the same row are arranged in a wave shape along the length direction of the heat sink 20.

[0027] Specifically, the plurality of rows of LED light sources 320 are arranged on the soft substrate 310, a specific arrangement direction is the length direction of the heat sink 20, i.e., an arrow direction shown in the drawings, two adjacent rows of LED light sources 320 are spaced apart at an interval, and the LED light sources 320 in the same row are arranged in a wave shape along the length direction of the heat sink 20, namely, when the luminaire is horizontally placed along a length direction thereof, the LED light sources 320 in the same row are not at the same horizontal height, and can be seen as a wave shape having an alternating pattern of crests and troughs (a wavy curve shown in the figure). This design may avoid the formation of a dark shadow due to the uniform arrangement of light sources when the luminaire rotates, thereby improving the illumination effect of the luminaire.

[0028] More further, the distance between each of the LED light sources 320 and the inner wall of the lampshade 10 is equal.

[0029] Specifically, the lampshade 10 and the heat sink 20 may be structurally regarded as two concentric cylinders, such that the distance between the lampshade 10 and the heat sink 20 is equal everywhere therebetween. When the light source assembly 30 is fixed to the outer wall of the heat sink 20, the distances between the plurality of LED light sources 320 in the light source assembly 30 and the inner wall of the lampshade 10 are equal, so that the light source assembly may emit light at 360 degrees, the emitted light may have a more uniform brightness around the luminaire, and then the use experience of the luminaire is improved.
