In prior art, since the film and television lamp has higher requirements for luminous power and heat dissipation performance, it is necessary to provide a larger number of light source devices with larger power, and provide radiators and heat dissipation fans which can meet corresponding heat dissipation requirements. In this way, a number of internal devices and overall weight of the film and television lamp are significantly increased, so that internal layout and housing structure of the film and television lamp need to be changed accordingly. At some areas of the housing structure of the film and television lamp, such as a rear side wall provided along a light outlet direction and in face to a light outlet part, irregular inclined surface will appear to form an inclined side wall. In one aspect, there is an obtuse intersection angle between the inclined side wall and its adjacent side wall (hereinafter referred to as an adjacent side wall), the inclined side wall is usually directly connected to the adjacent side wall, and a fixing part is provided respectively on the inclined side wall and the adjacent side wall to realize connection of the inclined side wall and the adjacent side wall. since an angle between the inclined side wall and the adjacent side wall is an obtuse angle rather than a right angle, the fixing part on one of the inclined side wall and the adjacent side wall needs to be configured to be consistent with a demoulding direction of a side wall connected to the fixing part, and has a sharp intersection angle with a demoulding direction of the side wall where the fixing part is located in. In this way, the fixing part forms an inverted buckle mechanism on the side wall where the fixing part is located in, it is difficult to demould unless providing a complex demoulding mechanism for demoulding, and it is difficult to align during assembly, thus increasing difficulty and cost of manufacturing and assembly process. In another aspect, due to obtuse angle between the inclined side wall and the adjacent side wall, gravity of devices provided in the adjacent area acts on the inclined side wall and produces tilting moment at a connecting part of the inclined side wall and the adjacent side wall, causing separation trend and fatigue failure risk of the connecting part between the inclined side wall and the adjacent side wall, and thus reducing connection reliability between the inclined side wall and the adjacent side wall; connection strength between the inclined side wall and the adjacent side wall is required to be increased, so that a plurality of the fixing parts need to be provided on the inclined side wall and the adjacent side wall to form multi-point connection, in order that a number of the buckle mechanism is further increased, and difficulties of demoulding of the side wall and structural complexity of the demoulding mechanism are increased, and difficulties and cost of manufacturing and assembly process are further increased.

As shown in FIGS. 1-3, embodiments of the present application provides a lighting lamp 1, which includes a first housing 10, a second housing 20 and at least one connecting component 30, thus reducing difficulty of production and assembly of the housing structure and improving reliability of connection.

The first housing 10 extends in a first direction and provided with a first fixing part 111, and the first fixing part 111 extends along the first direction. Here, a specific direction of the first direction can be determined according to actual needs, and the embodiments of the present application do not make limitation on it. In some embodiments, the first housing 10 can be an injection molded part, and the first direction can be a mold outlet direction of the first housing 10. In this way, the first housing 10 wholy extends along its mold outlet direction, and thus can be easily demoulded from a mould, reducing manufacturing difficulty of the first housing 10. For example, the first direction can be a horizontal direction, and the first housing 10 can extend along the horizontal direction.

The second housing 20 includes a body wall 211 and a second fixing part 212 provided on the body wall 211. The body wall 211 is provided on an end of the first housing 10 along the first direction, and an angle between a thickness direction of the body wall 211 and the first direction is a sharp angle. The second fixing part 212 extends along the thickness direction of the body wall 211 in order to make mold outlet direction of the second fixing part 212 and outlet direction of the body wall 211 consistent. The body wall 211 and the second fixing part 212 both can be moulded at once in order to reduce manufacturing difficulty of the second housing 20. Since the first fixing part 111 extends along the first direction, there is a sharp angle rather a vertical angle between an extending direction of the first fixing part 111 and an extending direction of the second fixing part 212.

Through connection between the at least one first connecting part 31a and the first fixing part 111, the at least one connecting component 30 can be connected with the first housing 10. And through connection between the at least one second connecting part 32a and the second fixing part 212, the at least one connecting component 30 can be connected with the second housing 20.

Thus the first housing 10 and the second housing 20 do not need to be directly fixedly connected with each other. The first fixing part 111 on the first housing 10 can be configured to extend along the first direction, in order to make mold outlet direction of the first fixing part 111 and mold outlet direction of the first housing 10 consistent, while the second fixing part 212 on the second housing 20 can extend along the thickness direction of the second housing 20, in order to make mold outlet directions of the second fixing part 212 and mold outlet directions of the body wall 211 consistent, so that there will be no inverted buckle mechanism at the first fixing part 111 and the second fixing part 212, and though the first housing 10 and the second housing 20 are easy to demould during manufacturing, there is no need to provide demoulding mechanism, and the first housing 10 and the second housing 20 can also be more conveniently aligned during assembly, reducing difficulty and cost of production manufacturing and assembly process; In another aspect, without increasing difficulty of demoulding, a required number of first fixing parts 111 and second fixing parts 212 can be provided according to requirement of bearing strength and structural layout, so as to overcome connected structure's separation trends caused by gravity and tilting moment of adjacent devices and risk of fatigue failure, and enhance carrying capacity of the second housing 20 for devices provided in the adjacent area.
