Components in the drawings are not drawn by ratio, and similar component marks are usually used to represent similar components.

The invention is further described in conjunction with the attached drawings and specific implementation mode.

Embodiment 1

As shown in FIG. 1, a lamp fixture provided by the invention includes a bottom cover 1 and a hanging board 3, wherein the hanging board 3 is installed on the bottom cover 1, and the hanging board includes a hanging board body 30. Refer to FIG. 2. The hanging board body 30 has two ends which are respectively provided with first fixing members and second fixing members, and the two ends are both provided with downward bent edges 36. The first fixing members 32 and the second fixing members 34 are respectively fixedly connected to lower end portions of respective bent edges 36 such that the first fixing members 32 and the second fixing members 34 are lower than the hanging board body 30, thus providing more operating space for installation. Refer to FIG. 4. The bottom cover 1 is provided with first openings 120 and second openings 140. First fixing portions 12 and second fixing portions 14 are respectively positioned in the first openings 120 and the second openings 140. The first fixing members 32 extend into the first openings 120 to be articulated with the first fixing portions 12, and the second fixing members 34 can extend into the second openings 140 to be fixed with the second fixing portions 14. Refer to FIG. 1. The fixed connection structure of the hanging board 3 and the bottom cover ensures that when the bottom cover 1 is fixed on the hanging board 3, the bottom cover 3 can be tightly adhered to the hanging board. In this way, the distance between a lamp body and the mounting surface is the thickness of the hanging board 3, so the whole lamp achieves a visual effect of seamless installation after installation.

Refer to FIG. 2 and FIG. 4. As shown in the figures, each one of the first openings 120 has a first relatively large opening portion 122 and a first relatively small opening portion 124, while each one of the second openings 140 has a second relatively large opening portion 142 and a second relatively small opening portion 144, and each one of the first relatively large opening portions 122 is adjacent to the corresponding one of the second relatively large opening portions 142. The first fixing members 32 are smaller than the first relatively large opening portions 122 and bigger than the first relatively small opening portions 144. The second fixing members 34 are smaller than the second relatively large opening portions 142 and bigger than the second relatively small opening portions 144. The first fixing members 32 can slide in the first openings 120, and the second fixing members 34 can slide in the second openings 140. When the first fixing members 32 and the second fixing members 34 are respectively fixed at the first relatively small opening portions 122 and the second relatively small opening portions 142, the hanging board 3 is fixed with the bottom cover 1. Further, in a preferred solution, as shown in FIG. 3, the first fixing portions 12 are first protruding blocks which are respectively positioned on two sides of the first relatively small opening portions and protrude downward; the middle portion of each one of the first protruding blocks is provided with a first groove 126 matched with the corresponding one of the first fixing members 32; the second fixing portions 14 are second protruding blocks which are positioned on two sides of the second relatively small opening portions and protrude downward; the middle portion of each one of the second protruding blocks is provided with a second groove 146 matched with the corresponding one of the second fixing members 34; when the first fixing members 32 are positioned in the first grooves 126, the second fixing members 34 are positioned in the second grooves 146.

Further preferably, as shown in FIG. 3, each one of the first protruding blocks is provided with first slopes 128 on the two sides along the sliding direction of the corresponding one of the first fixing members 32, wherein the inclinations of two first slopes on two sides of the first protruding blocks can be identical or different. Each one of the second protruding blocks is provided with a second slope 148 on one side along the sliding direction of the corresponding one of the second fixing members 34 and close to the corresponding one of the second relatively large opening portions 142. The slope design facilitates the sliding of the hanging board and makes the connection between the hanging board and the bottom cover more compact and solid. Refer to FIG. 3. More preferably, each one of the second grooves 146 is provided with a stopper portion 149 on a lateral side away from the corresponding one of the second relatively large opening portions 142, and when the second fixing members 34 contact the stopper portions 149, the second fixing members 34 are positioned in the second grooves 146.

Refer to FIG. 1-FIG. 4. The installation process of the lamp fixture is as follows. Fix the hanging board on the mounting surface first, then extend the first fixing members of the hanging boards into the bottom cover from the first relatively large opening portions, and move the first fixing members to the first relatively small opening portions such that the lamp body is hung on the first fixing members; after the lamp body is hung on the first fixing members, rotate the lamp body such that the second fixing members extend into the second relatively large opening portions; finally, move the lamp body along the length direction of the hanging board such that the second fixing members are pressed against the stopper portions. In such circumstances, the first fixing members are positioned in the first grooves, and the second fixing members are positioned in the second grooves, so the hanging board and the bottom cover are in fixed connection, completing the whole installation process. Such installation mode achieves a visual effect during the whole installation process, capable of further reducing the installation time and improving the installation efficiency.

Embodiment 2

This embodiment provides a surface mounted tube lamp and a lamp fixture. The lamp fixture is installed on a lamp body 2, wherein the lamp fixture is the lamp fixture described in embodiment 1. Preferably, the middle portion of the bottom cover is provided with a third groove 40, and the inner wall of the third groove is provided with at least one first through-hole 42 through which power wires pass. Further, as shown in FIG. 2, the hanging board 3 is positioned above the third groove 40 and is also provided with a second through-hole 38 through which the power wires pass. Refer to FIG. 1, FIG. 2 and FIG. 4. During installation of the surface mounted tube lamp, the external power wires can pass through the second through-hole 38 to enter the third groove 40, while the power wires of lighting components in the surface mounted tube lamp can extend out from the first through-hole 42, and the external power wires and the internal power wires of the surface mounted tube lamp are electrically connected in the third groove, so the whole power wiring is simple and beautiful.

Refer to FIG. 2. The hanging board 3 has two ends receptively provided with oval first mounting holes 50 and oval second mounting holes 52, wherein the extension lines of the long axes of the first mounting holes 50 are vertical to the extension lines of the long axes of the second mounting holes 52, thus limiting displacement of the hanging board caused by an external force and ensuring the stability of the installation.
