[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0023] Example 1:
[0024] like Figure 1 and Figure 2 As shown, an ambient light bracket with a foldable light-shielding structure mainly includes a bracket body 1. The bracket body 1 is integrally formed through an injection molding process. The bracket body 1 is provided with a light guide accommodating groove 1a extending from one end to the other. The groove walls on both sides of the light guide accommodating groove 1a are provided with light guide clipping protrusions 1d distributed along the length thereof. The thickness of the light guide clipping protrusions 1d gradually decreases from the groove opening of the light guide accommodating groove 1a to the groove bottom. The light guide clipping protrusions 1d on the groove walls on both sides are symmetrically distributed, that is, the light guide clipping protrusions 1d act in pairs, and together limit the linear light guide 3 to prevent the linear light guide 3 from sliding out of the light guide accommodating groove 1a. The light guide accommodating groove 1a is provided with light guide support ribs 1e distributed along the length thereof. The light guide support ribs 1e extend circumferentially from one groove opening to the other groove opening, and the light guide support ribs 1e provide support for the linear light guide 3. In this embodiment, each pair of light guide clipping protrusions 1d is arranged at equal distances, and a light guide support rib 1e is provided on both sides of each pair of light guide clipping protrusions 1d. The light guide clipping protrusions 1d and the light guide support rib 1e work together to make the installation structure of the linear light guide 3 more stable and reliable, not easy to shift, and reduce wear.
[0025] Furthermore, at least one end of the bracket body 1 is provided with a light-shielding flap 1b. The number of light-shielding flaps 1b depends on the light-intake method of the linear light guide 3. When the linear light guide 3 receives light from one end, only one light-shielding flap 1b is required. When the linear light guide 3 receives light from both ends, two light-shielding flaps 1b are required. The light-shielding flap 1b can be flipped open or closed over the notch of the light guide receiving slot 1a. The light-shielding flap 1b can be plugged in, snapped into, or otherwise closed over the notch of the light guide receiving slot 1a. In this embodiment, one side of the light-shielding flap 1b is connected to one side of the notch of the light guide receiving slot 1a via at least one foldable folding portion 1c. The other side of the light-shielding flap 1b can be connected to the other outer wall of the light guide receiving slot 1a via a snap-fit connection, resulting in a simple and reliable connection. According to the shape of the bracket body 1, a folding portion 1c is provided in this embodiment. The middle part of the folding portion 1c can be bent. One end of the folding portion 1c is connected to one side wall of the light guide accommodating groove 1a, and the other end is connected to one side outer wall of the light shielding flip cover 1b, so that the light shielding flip cover 1b can be folded. A first clip (1n) is provided on the other side outer wall of the light shielding flip cover 1b, and a corresponding first snap protrusion (1k) is provided on the other side outer wall of the light guide accommodating groove 1a. The first clip (1n) and the corresponding first snap protrusion (1k) can be snap-fitted. The shape of the first snap protrusion (1k) is not limited to a cone or other shape with a side bevel. The light shielding flip cover 1b is provided with a light guide clearance groove 1b1 extending from one end to the other end. The shapes of the light guide clearance groove 1b1 and the light guide accommodating groove 1a are both adapted to the shape of the linear light guide 3. When the light-shielding flip cover 1 b is buckled into the notch of the light guide accommodating groove 1 a , the light guide yielding groove 1 b 1 and the light guide accommodating groove 1 a together limit the linear light guide 3 .
[0026] Furthermore, one end of the bracket body 1, which has a light-shielding flap 1b, is enlarged to form a mounting seat retaining groove 1f. This mounting seat retaining groove 1f communicates with the light guide accommodating groove 1a. Second engaging protrusions 1m for mounting the bracket body 1 are provided on either side of the outer wall of the mounting seat retaining groove 1f. Two opposing lamp holder clamping arms 1g are provided on the side of the mounting seat retaining groove 1f facing away from the light guide accommodating groove 1a. Each lamp holder clamping arm 1g is provided with a sliding guide 1h extending along its length on either side, with a bayonet 1i disposed between the two sliding guides 1h of each lamp holder clamping arm 1g.
[0027] Example 2:
[0028] like Figures 2 to 5 As shown, a linear atmosphere lamp mainly includes the above-mentioned atmosphere lamp bracket with a folding shading structure, a lamp head 2 and a linear light guide 3.
[0029] See also Figure 2 and Figure 3The linear light guide 3 includes a light guiding section 3c, at least one end of which is connected in sequence to a light mixing section 3b and a light input section 3a. In this embodiment, the linear light guide 3 is light input at one end, and therefore, the linear light guide 3 includes a light input section 3a, a light mixing section 3b, and a light guiding section 3c connected in sequence. The linear light guide 3 is installed in the light guide accommodating groove 1a, and the light mixing section 3b can be shielded by the light shielding flip cover 1b. A limiting boss 3d extending circumferentially along the linear light guide 3 is provided between the light input section 3a and the light mixing section 3b. The limiting boss 3d serves as a limit when the light input section 3a is installed. A plurality of anti-rotation protrusions 3a1 and a third clamping protrusion 3a2 are provided on the outer circumference of the light input section 3a.
[0030] See also Figures 2 to 5 The lamp holder 2 includes a lamp housing 2a and a PCBA 2d integrated with a plurality of LED lamp beads 2d1. The lamp housing 2a includes a lamp housing body 2a1 and a shell cover 2a4 that snaps onto the lamp housing body 2a1. A mounting seat 2a2 protrudes from the lamp housing body 2a1 toward a side away from the shell cover 2a4. The lamp housing body 2a1 and the shell cover 2a4 together enclose a PCBA mounting cavity 2b. The PCBA 2d is mounted within the PCBA mounting cavity 2b. The mounting seat 2a2 is provided with a light guide mounting hole 2c extending from the outer end surface of the mounting seat 2a2 to the PCBA mounting cavity 2b. The inner wall of the light guide mounting hole 2c is provided with an anti-rotation groove 2c1 corresponding to each anti-rotation protrusion 3a1 and a fourth engaging protrusion 2a5 corresponding to each third engaging protrusion 3a2. The light inlet section 3a is inserted into the light guide mounting hole 2c, and its light inlet end face faces the light-emitting surface of each LED lamp bead 2d1. The third clamping protrusion 3a2 and the fourth clamping protrusion 2a5 are engaged with each other, and the anti-rotation groove 2c1 and the anti-rotation protrusion 3a1 are used to prevent rotation. Therefore, the connection between the linear light guide 3 and the lamp holder 2 is simple and reliable.
[0031] Furthermore, each side of the lamp housing body 2a1 is provided with a retaining slot 2a3 that mates with the corresponding sliding guide portion 1h, and a fifth engaging protrusion 2a6 that engages with the bayonet 1i. The sliding guide portion 1h of the lamp holder clamping arm 1g is inserted into the corresponding retaining slot 2a3 and snap-fits with the fifth engaging protrusion 2a6 via the bayonet 1i. At this point, one end of the retaining slot 2a3 rests against the end surface of the retaining slot 1f of the mounting base, near the sliding guide portion 1h, and the mounting base 2a2 is inserted into the retaining slot 1f. This simple and reliable connection between the lamp holder 2 and the bracket body 1 facilitates assembly.
