     DETAILED DESCRIPTION 
     Examples of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although examples of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the examples set forth herein. On the contrary, these examples are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. 
     It should be noted that the features in the examples of the disclosure can be combined with each other without conflict. Sometimes, when it is necessary to adjust the irradiation angle of the lamp, it is generally to adjust the irradiation angle of the lamp manually or by using tools, which can&#39;t intelligently adjust the irradiation angle according to personal wishes and cannot meet the needs of users. 
     As shown in  FIG. 1 , this embodiment discloses a cabinet lamp  100 . The cabinet lamp  100  includes a lamp housing, an elastic member  40 , and a light-emitting assembly  50 . The lamp housing includes a main shell  10 , and the main shell  10  includes a first shell plate  11  and second shell plate  12 . The first shell plate  11  and the second shell plate  12  are connected to each other, and the first shell plate  11  and the second shell plate  12  enclose a first space  13 . A surface of the first shell plate  11  surrounding the first space  13  or a surface of the second shell plate  12  surrounding the first space  13  is provided with a first connection part. The elastic member  40  is made of an elastic material and has suitable elasticity and rigidity. The elastic member  40  includes a second connection part, the elastic member  40  fits with the first space  13  in a plugging-in manner, and the second connection part is in snap fit with the first connection part. The elastic member  40  is configured to be installed on an inner top wall  211  of a lamp cabinet  200 . The light-emitting assembly  50  is installed on the lamp housing. 
     The lamp cabinet  100  of this embodiment has following advantages: after the elastic member  40  is installed on the inner top wall of the lamp cabinet  200 , the first space  13  of the lamp housing is aligned with the second connection part, and then the lamp housing is pushed towards the inner top wall  211  of the lamp cabinet  200 , so that the second connection part enters the first space  13  first, and then the first connection part is in snap fit with the second connection part, thereby realizing the connection between the lamp housing and the elastic member  40 . Compared with the existing cabinet lamp, the lamp housing of the cabinet lamp  100  of this embodiment and the cabinet lamp  100  of this embodiment are more convenient to be installed on the inner top wall  211  of the lamp cabinet  200 . Due to the existence of the first space  13 , and the elastic member  40  fits with the first space  13  in a plugging-in manner, that is, a part of the elastic member  40  is located in the first space  13 , the occupied space of the cabinet lamp is reduced. 
     When disassembling the lamp housing, the lamp housing is pulled away from the inner top wall  211  of the lamp cabinet  200 , so that the lamp housing can be separated from the elastic member  40 . It is more convenient to detach the lamp housing of the cabinet lamp  100  of this embodiment from the inner top wall  211  of the lamp cabinet  200 . 
     Additionally or alternatively, as shown in  FIG. 4 , the elastic member  40  of this embodiment is formed by bending an integrally metal sheet, and the elastic member  40  has few parts, which does not need to be assembled, it is relatively convenient to install and disassemble, and it has low cost. 
     The first connection part may be a groove, and correspondingly, the second connection part is a protrusion. The first connection part may be a protrusion, and correspondingly, the second connection part is a groove. The first connection part may be arranged on a surface of the first shell plate  11  enclosing the first space  13 , or the first connection part may also be arranged on a surface of the second shell plate  12  enclosing the first space  13 . If the first connection part is arranged on the surface of the second shell plate  12  surrounding the first space  13 , it is not convenient for an end cover  20  described below to be plugged in and fits with the main shell  10 . If the first connection part is arranged on the surface of the first shell plate  11  surrounding the first space  13 , and the first connection part is a protrusion and the second connection part is a groove, the first space  13  will be occupied, so that it is not convenient for the end cover  20  described below to be plugged in and fits with the main shell  10 , or the entire occupied space of the cabinet lamp  100  needs to be increased. Therefore, in order to facilitate the plug fitting with each other between the end cover  20  and the main shell  10 , and in order to reduce the volume of the cabinet lamp  100 , Additionally or alternatively, a first groove  1121  is formed on the surface of the first shell plate  11  surrounding the first space  13  in this embodiment, and the first groove  1121  is the first connection part. The elastic member  40  includes a first protrusion  421 , and the first protrusion  421  is the second connection part. 
     Additionally or alternatively, a surface of the first groove  1121  is an arc surface, and a surface of the first protrusion  421  facing the first groove  1121  is an arc surface. The advantage is that, when the cabinet lamp  100  is installed, the lamp housing is pushed toward the inner top wall  211  of the lamp cabinet  200 , so that the first protrusion  421  enters the first space  13  first, and then the first protrusion  421  can smoothly enter the first groove  1121  along the arc surface of the first groove  1121 , thereby realizing the snap-fit between the first groove  1121  and the first protrusion  421 , that is, the snap-fit between the second connection part and the first connection part is realized. When disassembling the lamp housing of the cabinet lamp  100 , the lamp housing is pulled away from the inner top wall  211  of the lamp cabinet  200 , and the first protrusion  421  can be smoothly separated from the first groove  1121  along the arc surface of the first groove  1121 , thereby completing the disassembly of the lamp housing from the inner top wall  211  of the lamp cabinet  200 . That is, in this embodiment, the surface of the first groove  1121  is an arc surface, and the surface of the first protrusion  421  facing the first groove  1121  is an arc surface, so that it is relatively convenient for the connection and disassembly of the lamp housing and the elastic member  40 . 
     As shown in  FIG. 2  and  FIG. 3 , the cabinet lamp  100  of this embodiment may be a strip lamp. Additionally or alternatively, two second shell plates  12  are provided, the first shell plate  11  is arranged between the two second shell plates  12 , and the two long sides of the first shell plate  11  are connected to the second shell plates  12  respectively, that is, the two ends of the first shell plate  11  in a width direction are connected to the second shell plates  12 , respectively. Specifically, the two ends of the first shell plate  11  in the width direction are connected to an inner surface of a middle position of second shell plate  12 , respectively. At least two elastic members  40  are provided, as shown in  FIG. 2 , two elastic members  40  are provided, and the two elastic members  40  are arranged at a spacing. 
     Both of a surface of the second shell plate  12  facing the first shell plate  11  and a surface of the second shell plate  12  for enclosing an installation cavity  60  are inner surfaces. An outer surface of the first shell plate  11  and an inner surface of one of the second shell plates  12  enclose a first space  13 , and the outer surface of the first shell plate  11  and the inner surface of the other second shell plate  12  enclose another first space  13 . Each of the two first spaces  13  is arranged along a length direction of the lamp housing, and the two first spaces  13  are symmetrically arranged in the width direction of the lamp housing. The elastic member  40  includes a connection part  41  and two main bodies  42  connected at two ends of the connection part  41 . Each of the two main bodies  42  is provided with the first protrusion  421 . The two main bodies  42  of the elastic member  40  fits with the two first spaces  13  in a plugging-in manner, respectively, and the two first protrusions  421  are in snap fit with the two first grooves  1121 , respectively, which improves the connection reliability between the lamp housing and the elastic member  40  and allows the lamp housing to subject a uniform stress. The connection part  41  and the two main bodies  42  enclose a clamping space  43 , and the first shell plate  11  is plugged into the clamping space  43 . 
     The first shell plate  11  includes a main plate  111  and two side plates  112 , two ends of the main plate  111  in a width direction are connected to the two side plates  112 , respectively. A surface of the main plate  111  facing the inner top wall  211  of the lamp cabinet  200  is an outer surface, and the side plate  112  extends away from an outer surface of the main plate  111 . The side plate  112  and the second shell plate  12  are connected to each other, and an outer surface of the side plate  112  and the inner surface of the second shell plate  12  enclose a first space  13 . The main plate  111  and a part of the side plate  112  are located in the clamping space  43 . 
     As shown in  FIG. 4 , Additionally or alternatively, the connection part  41  is partially bent to form a second protrusion  411 , and a length direction of the second protrusion  411  is parallel to a length direction of the first shell plate  11 . As shown in  FIG. 3 , the second protrusion  411  faces the first shell plate  11 . The advantage of forming the second protrusion  411  by bending the connection part  41  partially is that the second protrusion  411  encloses a groove, which provides a space for the deformation of the elastic member  40  and reduces the difficulty of the deformation of the elastic member  40 , thereby increasing the ease of the snap-fit between the first protrusion  421  and the first groove  1121 , and also increasing the ease of separation between the first protrusion  421  and the first groove  1121 . In this way, it is convenient to connect and disassemble the lamp housing and the elastic member  40  in this embodiment. In order to further reduce the difficulty of the deformation of the elastic member  40 , two second protrusions  411  are provided in this embodiment, and the two second protrusions  411  are symmetrically arranged. 
     As shown in  FIG. 4 , Additionally or alternatively, the connection part  41  is provided with a mounting hole  412 , the mounting hole  412  is arranged between the two second protrusions  411 , and the mounting hole  412  is configured to connect to the inner top wall  211  of the lamp cabinet  200 . The elastic member  40  can be installed on the inner top wall  211  of the lamp cabinet  200  by putting a screw to pass through the mounting hole  412 . The advantage of forming the mounting hole  412  in the connection part  41  is that the volume of the elastic member  40  is not increased, which is beneficial for the cabinet lamp  100  of this embodiment to occupy a less space. 
     Additionally or alternatively, one end of the second shell plate  12  surrounding the first space  13  is an inner end, a surface of the connection part  41  facing away from the first shell plate  11  is an outer surface, and the outer surface of the connection part  41  is coplanar with an end surface of the inner end of the second shell plate  12 . Therefore, after the elastic member  40  is connected to the lamp housing, the elastic member  40  is hidden between the two second shell plates  12 , and the elastic member  40  cannot be seen from the outside, which allows the cabinet lamp  100  of this embodiment to be more beautiful and to reduce the space occupied by the cabinet lamp  100  of this embodiment in the lamp cabinet  200 . 
     Additionally or alternatively, the lamp housing has an installation cavity  60 , and the light-emitting assembly  50  is arranged in the installation cavity  60 . The light-emitting assembly  50  includes a light board  51  and a light body installed on the light board  51 . Two ends of the light board  51  are installed on two adjacent inner walls of the lamp housing, respectively, that is, the light board  51  in this embodiment is obliquely arranged in the installation cavity  60 . An intersection angle is formed between the light board  51  and the second shell plate  12 , and the intersection angle between the light board  51  and the second shell plate  12  ranges from 20 degrees to 70 degrees. After the cabinet lamp  100  is installed on the inner top wall  211  of the lamp cabinet  200 , an intersection angle between the light board  51  and an inner bottom wall  221  is formed and is in a range from 20 degrees to 70 degrees; in this angle range, more light from the light body can be irradiated to an inner side wall  231  of the lamp cabinet  200 . The light irradiating on the inner side wall  231  of the lamp cabinet  200  is reflected by the inner side wall  231  and then irradiates on the inner bottom wall  221  of the light cabinet  200  to illuminate an object in the lamp cabinet  200 . Because the light for illuminating the object in the lamp cabinet  200  is a reflected light, no glare occurs, and there is no need to install a diffusion plate in the lamp housing to uniform the light. In this way, the volume of the lamp housing is reduced, and the lamp housing in this embodiment is thinner and a less space is occupied. 
     Additionally or alternatively, each of two adjacent inner walls of the lamp housing is provided with a slot, and two ends of the light board  51  in a width direction fits with the slots in a plugging-in manner, respectively. When installing the light board  51  in the installation cavity  60  of the lamp housing, the two ends of the light board  51  in a width direction are plugged into the two slots, respectively, which is convenient for installing the light board  51 . When disassembling the light board  51 , the light board  51  can be drawn out from the slots, and it is convenient to disassemble the light board  51 . Specifically, as shown in  FIG. 3 , an inner surface of the first shell plate  11  is provided with a first slot  1111 , and an inner surface of the second shell plate  12  located in the installation cavity  60  is provided with a second slot  122 . The two ends of the light board  51  fits with the first slot  1111  and the second slot  122  in a plugging-in manner, respectively. 
     Additionally or alternatively, the main shell  10  of this embodiment is an integrally formed member, that is, the first shell plate  11  and the second shell plate  12  of this embodiment are integrally formed, so that the main shell  10  does not need to be assembled, which also allows the installation and disassembly of the main shell  10  to be more convenient. 
     As shown in  FIG. 2  and  FIG. 5 , Additionally or alternatively, the lamp housing of this embodiment further includes an end cover  20 , a part of the second shell plate  12  surrounding the first space  13  is an inner section, and the inner section of the second shell plate  12  is provided with a first limiting protrusion  121 . The end cover  20  is provided with a guide part  21 , and the guide part  21  may be an inserting block. The guide part  21  fits with the first space  13  in a plugging-in manner, and the first limiting protrusion  121  is configured to limit the guide part  21 . The connection structure between the end cover  20  and the main shell  10  is simple and convenient. The end cover  20  can be detached from the main shell  10 , so that it is convenient to replace the light-emitting assembly  50  in the installation cavity  60  of the lamp housing. Each of two ends of the end cover  20  in a width direction is provided with a guide part  21 , and the two guide parts  21  fits with the two first spaces  13  in a plugging-in manner, respectively. The end cover  20  may be an injection molding part, which has high molding efficiency, low cost, few components, and convenient installation and disassembly. 
     Specifically, one end of the second shell plate  12  surrounding the first space  13  is an inner end, and the first limiting protrusion  121  is provided on the inner end of the second shell plate  12  and the first limiting protrusion  121  faces the first space  13 . A gap is provided between the first limiting protrusion  121  and the first shell plate  11 , which enables the main body  42  of the elastic member  40  to enter the first space  13  through the gap, and enable the first protrusion  421  on the main body  42  to be in snap fit with the first groove  1121 . It is more convenient to arrange the first limiting protrusion  121  on the inner end of the second shell plate  12  than to arrange the first limiting protrusion  121  at other positions on the inner section of the second shell plate  12 . 
     In order to further improve the connection reliability between the end cover  20  and the main shell  10 , it is preferable that the end cover  20  and the main plate  111  are in snap fit with each other in this embodiment, so that it is convenient to connect the end cover  20  and the main plate  111 , and it is also convenient to separate the end cover  20  from the main plate  111 . After the end cover  20  is clamping in the main plate  111 , the end cover  20  cannot move in the length direction of the lamp housing. In order to allow the end cover  20  to be immovable in the width direction of the lamp housing and to fix the position of the end cover  20 , Additionally or alternatively, the outer surface of the first shell plate  11  and the inner surface of the second shell plate  12  in this embodiment enclose a limiting groove  14 , one limiting groove  14  is provided. The guide part  21  is plugged into the limiting groove  14 , and the limiting groove  14  is configured to limit the guide part  21 . After the guide part  21  is plugged into the limiting groove  14 , the guide part  21  cannot move in the width direction of the lamp housing, and then the entire end cover  20  cannot move in the width direction of the lamp housing. 
     If each of the two first spaces  13  is provided with the limiting groove  14 , and the two guide parts  21  need to be limit fitting with the two limiting grooves  14 , respectively, it will increase the difficulty of installing the end cover  20  on the main shell  10 , or needs to improve the machining accuracy of the limiting groove  14  and the guide part  21 , thereby increasing the processing cost. In this embodiment, in order to reduce the difficulty of installing the end cover  20  to the main shell  10  and to reduce the cost, as shown in  FIG. 2 , one of the first spaces  13  has a limiting groove  14 , and the other first space  13  has no limiting groove  14 . The advantage of one limiting groove  14  is that it is convenient for one of the guide parts  21  to enter into the limiting groove  14 , thereby facilitating the connection between the end cover  20  and the main shell  10 . 
     Additionally or alternatively, in this embodiment, the end cover  20  and the main plate  111  are in snap fit with each other in two ways. The first way is that the main plate  111  is provided with at least two clamping grooves  1112 , the at least two clamping grooves  1112  are arranged at a spacing in a width direction of the main plate  111 , and the at least two clamping grooves  1112  are distributed at different length positions of the main plate  111 . The end cover  20  is provided with at least two fastening-holding parts  22 , the fastening-holding parts  22  may be clamping blocks, and the clamping grooves  1112  are in snap fit with the fastening-holding parts  22 , respectively. The second way is that the end cover  20  is provided with at least two clamping grooves  1112 , the at least two clamping grooves  1112  are arranged at a spacing in a width direction of the end cover  20  and the at least two clamping grooves  1112  are distributed at different length positions of the end cover  20 . The main plate  111  is provided with at least two fastening-holding parts  22 , and the clamping grooves  1112  are in snap fit with the fastening-holding parts  22 , respectively. Because a length of the cabinet lamp  100  is relatively long, in this embodiment, the at least two clamping grooves  1112  or the at least two fastening-holding parts  22  are arranged at different width positions of the cabinet lamp  100  and different length positions of the cabinet lamp  100 , which is beneficial for the first shell plate  11  to subject a uniform stress. 
     As shown in  FIG. 3 , the cabinet lamp  100  of this embodiment further includes a light-transmitting cover  30 . The inner surface of the first shell plate  11 , the inner surface of the second shell plate  12 , the light-transmitting cover  30 , and the end cover  20  enclose the installation cavity  60  of the lamp housing. 
     A part of the second shell plate  12  surrounding the first space  13  is an inner section, and another section of the second shell plate  12  is an outer section. The light-transmitting cover  30  fits with the outer section of the second shell plate  12  in a plugging-in manner. Specifically, one end of the second shell plate  12  surrounding the first space  13  is an inner end, and another end of the second shell plate  12  is an outer end. The light-transmitting cover  30  fits with the outer end of the second shell plate  12  in a plugging-in manner. The light of the light body on the light board  51  obliquely irradiates the light-transmitting cover  30  and exits from the light-transmitting cover  30 .
