Referring to <FIG>, which is a schematic stereostructure diagram of a luminaire according to an embodiment of the present disclosure, the luminaire includes a lampshade <NUM>, a heat sink <NUM>, and a light source assembly <NUM>.

The lampshade <NUM> and the heat sink <NUM> are both of a cylindrical structure, and the heat sink <NUM> is arranged inside the lampshade <NUM>.

The light source assembly <NUM> includes a soft substrate <NUM> and LED light sources <NUM>, the LED light sources <NUM> are arranged on the soft substrate <NUM>, one surface, facing away from the LED light sources <NUM>, of the soft substrate <NUM> is attached to an outer wall of the heat sink <NUM> and is wrapped around the outer wall of the heat sink <NUM>, and the LED light sources <NUM> are separated from an inner wall of the lampshade <NUM> by a threshold distance.

Specifically, the lampshade <NUM> 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 <NUM> has a cylindrical appearance, and the heat sink <NUM> is arranged in a hollow structure of the lampshade <NUM> of a cylindrical structure.

The light source assembly <NUM> is arranged between the lampshade <NUM> and the heat sink <NUM>. Specifically, the soft substrate <NUM> is arranged on an outer surface of the heat sink <NUM>. The soft substrate <NUM> here includes, but is not limited to, a flexible PCB board. One surface of the soft substrate <NUM> is attached to the outer wall of the heat sink <NUM>. A specific connection manner includes, but is not limited to, fixed connection with the outer wall of the heat sink <NUM> via plastic rivets. The other surface of the soft substrate <NUM> is used for arranging the LED light sources <NUM> to allow the LED light sources <NUM> to form a light-emitting surface on the surface, facing away from the heat sink <NUM>, of the soft substrate <NUM>. The soft substrate <NUM> is wrapped around the outer wall of the heat sink <NUM>, so that the light source assembly <NUM> forms a light-emitting bar on a periphery of the heat sink <NUM>, the luminaire forms a light source bar capable of emitting light at <NUM> 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.

In addition, the LED light sources <NUM> are separated from the inner wall of the lampshade <NUM> by a threshold distance, which makes the light transmitted from the lampshade <NUM> softer, and at the same time, facilitates air circulation so as to effectively dissipate heat from the LED light sources <NUM>.

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

It is to be understood that term used in the embodiments of the present disclosure is for the purpose for descripting the specific embodiments, rather than limiting the present application. The singular forms "a", "an", "the" and "said" used in the embodiments of the present application and the appended claims also include multiple forms. Generally, "multiple" includes at least two unless the context clearly indicates other meanings, but does not exclude the situation of including at least one.

It is to be understood that term "and/or" used in the present disclosure is only an association relationship describing associated objects and represents existence of three relationships. For example, A and/or B may represent three conditions, i.e., independent existence of A, coexistence of A and B and independent existence of B. In addition, character "/" in the present disclosure usually represents that previous and next associated objects form an "or" relationship.

It should be understood that although the terms first, second, third, etc. may be used to describe certain components in the embodiments of the present disclosure, these components should not be limited only to those terms. These terms are only used to distinguish the components from each other. For example, a first certain component may also be referred to as a second certain component without departing from the scope of the embodiments of the present disclosure. Similarly, a second component may also be referred to as a first certain component.

Depending on the context, the words "if" and "in case of" used herein may be interpreted to mean "when" or "while" or "in response to determining" or "in response to monitoring". Similarly, depending on the context, the phrase "if determined" or "if monitored (conditions or events stated)" can be interpreted as "when determined" or "in response to determination" or "when monitored (stated condition or event)" or "in response to monitor (conditions or events stated)".

In the embodiments of the present disclosure, "substantially equal to", "substantially perpendicular to", "substantially symmetrical", etc. mean that the macroscopic size or relative positional relationship between the two features is extremely close to the relationship described. However, it is clear to those skilled in the art that the positional relationship of an object is difficult to be constrained at a small scale or even a microscopic angle due to the existence of objective factors such as errors and tolerances. Therefore, even if there is a slight error in the size and positional relationship between the two, it does not have a great influence on the realization of the technical effect of the present disclosure.

It should also be noted that the terms "including", "containing" or any other variations thereof are intended to encompass a non-exclusive inclusion, such that the item or system including a series of elements includes not only those elements but also other elements not explicitly listed, or elements that are inherent to such item or system. In the absence of more restrictions, an element defined by the phrase "including one. " does not exclude the existence of additional identical elements in the item or system that includes the element.

In the above-described embodiments, although the above method is illustrated and described as a series of acts for the purpose of simplifying the explanation, those skilled in the art will understand and appreciate that these methods are not limited by the order of actions, because in one or more embodiments, some acts may occur in a different order and/or concurrently with other acts from the illustration and description herein or illustrated or described herein, but which may be understood by those skilled in the art. Those skilled in the art will appreciate that information, signals, and data may be represented using any of a variety of different technologies and techniques. For example, the data, instructions, commands, information, signals, bits (bits), symbols, and chips referenced throughout the above description may be by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof to represent.
