For example, it can be fixedly connected, detachably connected or integrated; it can be mechanically connected or electrically connected; it can be directly connected, indirectly connected through an intermediate medium, and can be the internal connection of two elements or the interaction relationship of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

As shown in FIGS. 1 to 4, the luminaire of the embodiment of the present disclosure is suitable for, but not limited to, automobile, motorcycle, ship and various luminaire application places, for example, severing as car lamps, spotlights, plant lamps, wall washer lamps, street lamps or light pipes. The luminaire comprises a lamp shell 10, a light-transmitting panel 20, a light source assembly 30 and two end covers 40, wherein the lamp shell 10 is provided with an installation cavity 11 with an opening at the front side, and the light source assembly 30 is arranged in the installation cavity 11. The lamp shell 10 provides support and installation for the entire structure. The light source assembly 30 gives out light after being connected to the external power supply, playing a lighting role. On the one hand, the light-transmitting panel 20 seals the opening formed at the front side of the installation cavity 11, and on the one hand it plays a role in transmitting light.

Furthermore, as shown in FIGS. 3 and 4, the luminaire further includes a sealing strip assembly 50, and the inner wall of the installation cavity 11 is provided with upper embedding groove 12 and lower embedding groove 13 corresponding to each other at a position close to the opening. The upper and lower ends of light-transmitting panel 20 are respectively embedded into the upper embedding groove 12 and the lower embedding groove 13. And the light-transmitting panel 20 is abutted against the inner wall of the upper embedding groove 12 and the inner wall of the lower embedding groove 13 by the sealing strip assembly 50, i.e. the sealing strip assembly 50, via the light-transmitting panel 20, is jointly pressed by the inner wall of the upper embedding groove 12 and the inner wall of the lower embedding groove 13. Thus, on one hand the position of the light-transmitting panel 20 is fixed, and on the other hand the gap between the light-transmitting panel 20 and the inner wall of the upper embedding groove 12 and the gap between the light-transmitting panel 20 and the lower embedding groove 13 are sealed. The two end covers 40 are respectively fixed at the opposite ends of the lamp shell 10, and jointly restrict the light source assembly 30, the light-transmitting panel 20 and the sealing strip assembly 50 from coming out from the two sides of the installation cavity 11. In this way, the light source assembly 30, the light-transmitting panel 20 and the sealing strip assembly 50 cannot come out of the installation cavity 11 from both sides of the installation cavity 11.
