Referring to fig. 1 to 6, an embodiment of the present application discloses a lighting fixture, which includes a substrate 100, a mounting portion 200, and a light source module 300.

The substrate 100 is a base member of the lighting fixture, and the substrate 100 can provide a mounting base for other components of the lighting fixture. The first side 130 of the substrate 100 is provided with the printed circuit 120, avoiding the need for a separate circuit board arrangement in the lighting fixture. Under the condition, the substrate 100 can serve as a partial shell and a power module of the existing lighting lamp, so that the substrate 100 achieves the effect of multiple purposes, the number of parts of the lighting lamp can be reduced, the structure of the lighting lamp is simplified, and the number of parts of the lighting lamp is reduced. The specific process of disposing the printed circuit 120 on the substrate 100 is known in the art, and for the sake of brevity, will not be described herein again.

Substrate 100 and mounting portion 200 are disposed opposite to each other so that substrate 100 and mounting portion 200 form a housing of the lighting fixture, and since substrate 100 and mounting portion 200 may be plate-shaped members and substrate 100 and mounting portion 200 are disposed opposite to each other, substrate 100 may be attached to mounting portion 200, and therefore, the thickness of the housing formed by substrate 100 and mounting portion 200 is small, and the lighting fixture can be disposed thinly and has a neat and tidy appearance, so that the appearance of the lighting fixture is simplified. Specific kinds of the substrate 100 and the mounting portion 200 may be various, for example, a hard plastic plate, an acrylic plate, a metal plate, and the like, which is not limited in the embodiment of the present application.

Specifically, the first surface 130 of the substrate 100 faces the mounting portion 200, that is, the surface of the substrate 100 opposite to the mounting portion 200 is the first surface 130, so that the printed circuit 120 is located in the lighting fixture, and the printed circuit 120 is prevented from being exposed outside the lighting fixture to affect the appearance of the lighting fixture, and meanwhile, the printed circuit 120 is located in the lighting fixture to further protect the printed circuit 120, so that impurities (dust or liquid) are prevented from falling on the printed circuit 120, and accordingly, poor stability of the printed circuit 120 due to the impurities is avoided.

Mounting hole 210 has been seted up to installation department 200, and light source module 300 sets up in mounting hole 210, that is to say, light source module 300 inlays and establishes in installation department 200, and under this kind of circumstances, light source module 300 and installation department 200 share the thickness space of illumination lamps and lanterns to make light source module 300 not occupy the extra thickness space of illumination lamps and lanterns, avoid leading to the thickness size of illumination lamps and lanterns great because of light source module 300 and installation department 200 superpose in proper order, and then make illumination lamps and lanterns set up thinly.

Meanwhile, the light source module 300 is electrically connected to the printed circuit 120, specifically, the mounting hole 210 may be a through hole, and a portion of the light source module 300 may pass through the mounting hole 210 and be directly electrically connected to the printed circuit 120, so as to avoid adding other electrical connection components in the lighting fixture, so as to electrically connect the light source module 300 to the printed circuit 120.

In the lighting fixture disclosed in the embodiment of the present application, the substrate 100 is disposed opposite to the mounting portion 200, the printed circuit 120 is disposed on the first surface 130 of the substrate 100 facing the mounting portion 200, the light source module 300 is disposed in the mounting hole 210, and the light source module 300 is electrically connected to the printed circuit 120. In this scheme, printed circuit 120 directly sets up on base plate 100, avoids setting up solitary circuit board device in the illumination lamps and lanterns to make base plate 100 reach the effect that a thing is multi-purpose, thereby can simplify the structure of illumination lamps and lanterns, reduce the spare part quantity of illumination lamps and lanterns, and then make things convenient for the staff to carry out the dismouting of illumination lamps and lanterns.

Meanwhile, the light source module 300 and the mounting part 200 share the thickness space of the lighting fixture, so that the light source module 300 does not occupy the extra thickness space of the lighting fixture, and the situation that the thickness size of the lighting fixture is large due to the fact that the light source module 300 and the mounting part 200 are sequentially overlapped is avoided, and the lighting fixture can be arranged to be thin. Therefore, the problems of large thickness and inconvenient disassembly and assembly of the lighting lamp are solved.

Specifically, the lighting fixture may have a housing, and the substrate 100 has a second surface opposite to the first surface 130, and at least a portion of the second surface constitutes one of outer surfaces of the housing, so as to simplify a structure of the lighting fixture and reduce the number of components of the lighting fixture.

The thickness of the substrate 100 may be determined according to the size of the substrate 100, that is, the area of the substrate 100, and when the substrate 100 is larger, the thickness of the substrate 100 also needs to be larger to meet the strength requirement of the lighting fixture. Of course, the thickness of the substrate 100 may be determined by the material of the substrate 100, for example, the thickness of the iron substrate 100 may be smaller than the thickness of the aluminum substrate 100 in the case of the same size.

Meanwhile, the light and thin aluminum plate is also beneficial to heat dissipation of the lighting lamp, so that the heat dissipation performance of the lighting lamp is excellent.

Further, the mounting portion 200 may be an aluminum-plastic plate, which has a relatively small weight and a relatively high strength, and thus the lighting fixture can be further made light and thin.
