[0030] like Figures 1-6 As shown, in one embodiment of this utility model, an in-vehicle reading light is provided, including a housing 10, a circuit board 20, five light guides 30, and a shielding member 40. The circuit board 20 is fixed inside the housing 10 and has five sets of light-emitting units 21, each set of light-emitting units 21 including two LED beads. The light guides 30 are made of PC material or acrylic material. The five light guides 30 are disposed inside the housing 10, and each light guide 30 corresponds to a set of light-emitting units 21. The light guide 30 has a light-incident surface 31, a light-emitting surface 32, and a reflective surface 33. The light-incident surface 31 is close to the light-emitting unit 21. The light emitted by the light-emitting unit 21 is incident on the light-incident surface 31, then reflected by the reflective surface 33 to the light-emitting surface 32, and finally emitted by the lamp head 60. The shielding member 40 is made of silicone material. The shielding member 40 is located on the side of the circuit board 20 facing the light guide member 30. The shielding member 40 has five through holes 41, each through hole 41 corresponding to a set of light-emitting units 21. The inner wall of the through hole 41 surrounds the light-emitting unit 21. The edge of the through hole 41 is provided with a light-blocking protrusion 42, which extends away from the circuit board 20.

[0031] This embodiment discloses an in-vehicle reading light. By designing a shielding component 40 on the circuit board 20, and since the inner wall of each through-hole 41 surrounds the corresponding light-emitting unit 21, and the edge of the through-hole 41 is designed with a light-blocking protrusion 42, the light-blocking protrusion 42 can block the light emitted by the light-emitting unit 21 from shining onto the adjacent light guide component 30. This ensures that the light emitted by each light-emitting component can be incident on the light-incident surface 31 as much as possible, improving the uniformity of the light emission of the in-vehicle reading light. At the same time, this in-vehicle reading light abandons the traditional method of directly fixing the light-blocking block on the circuit board 20, reducing the difficulty of processing and assembly and the production cost.

[0032] In one embodiment, five groups of light emitting units 21 are arranged at intervals along the length direction of the shell 10, and the light blocking protrusions 42 are arranged between two adjacent light guides 30. Only the middle three of the five through holes 41 are designed with the light blocking protrusions 42, and the two through holes 41 at the ends are not designed with the light blocking protrusions 42, because there is no other light guide 30 in front of the corresponding light guide 30, which will not cause any impact. At the same time, the inner wall of the shell 10 will also block the light emitted by the two light emitting units 21 at the ends, so the two through holes 41 at the ends do not need to be additionally designed with the light blocking protrusions 42.

[0033] In one embodiment, the edge of the shielding piece 40 is bent to form a flange 43, and the flange 43 is attached to the side wall of the circuit board 20. The shielding piece 40 is in a block structure, and by designing the flange 43 at the edge of the shielding piece 40, the flange 43 can limit the position of the shielding piece 40 installed on the circuit board 20, so that the positioning accuracy of the through hole 41 and the light emitting unit 21 is improved during assembly. Further, the shielding piece 40, the light blocking protrusion 42 and the flange 43 are integrally formed.

[0034] In one embodiment, the four corners of the circuit board 20 are respectively provided with mounting holes 22, and the four corners of the shielding piece 40 are respectively provided with accommodation notches 44, and each accommodation notch 44 corresponds to one mounting hole 22. The circuit board 20 is fastened to the shell 10 by passing through the mounting hole 22 with a bolt, and the design of the accommodation notch 44 can make the mounting hole 22 completely exposed, so as to facilitate the bolt to pass through during assembly.

[0035] In one embodiment, the circuit board 20 is provided with two first positioning holes 23, and the shielding piece 40 is provided with a second positioning hole 45 corresponding to the first positioning hole 23. By designing the first positioning hole 23 and the second positioning hole 45 to cooperate, the installation position of the shielding piece 40 on the circuit board 20 is unique, so that the shielding piece 40 and the circuit board 20 are quickly aligned during assembly.

[0036] In one embodiment, in order to facilitate the installation and fixation of the five light guides 30, the shell 10 is provided with a support 50, and the support 50 is connected with each light guide 30.

[0037] In the specification of the utility model, a large number of specific details are explained. However, it can be understood that the embodiments of the utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail, so as not to obscure the understanding of the specification.

[0038] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
