[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] A reading light is a light that can provide certain lighting conditions for reading when the light is insufficient, and will not cause too much interference to other family members. The inventor has found that in order to facilitate the turning on of the reading light in a dark environment, an indicator light board will be considered to be set at the position of the outer cover plate, so as to provide guidance by emitting light when the user touches the outer cover plate. However, there is a certain gap between the indicator light board and the outer cover plate, so the light beam generated by the indicator light board is prone to divergence during the propagation process, which in turn causes the light beam to leak and affect the indication effect.

[0039] Please refer to Figure 1 and Figure 2The indicator light guide structure 100 and the reading light 1000 provided in the embodiment of the utility model can solve the above problems, which will be described in detail below.

[0040] refer to Figure 1 and Figure 2 The indicator light guide structure 100 is used for a reading lamp 1000. The indicator light guide structure 100 includes an indicator light board 110, an inner cover plate 120 and an outer cover plate 130. A lamp bead 111 is arranged on the indicator light board 110. A light focusing portion 121 is formed on the inner cover plate 120. The light focusing portion 121 is supported on the indicator light board 110 and surrounded by the lamp bead 111. The outer cover plate 130 is provided with a light-transmitting hole 131, and the light-transmitting hole 131 is communicated with the inner cavity of the light-focusing portion 121.

[0041] The indicator light guide structure 100 can generate a light beam through the lamp bead 111, which is supported by the indicator light board 110 through the focusing portion 121 and surrounded by the lamp bead 111, thereby avoiding a light leakage gap between the focusing portion 121 and the indicator light board 110, reducing the light beam diverging toward the surroundings, so that most of the light beam can move from the inner side of the focusing portion 121 toward the light-transmitting hole 131 and output, thereby converging the light beam and preventing it from excessively diverging to avoid affecting the indication effect.

[0042] It is worth noting that in order to make the light beam more concentrated during transmission from the focusing portion 121 to the light-transmitting hole 131, the light-transmitting area of ​​the light-transmitting hole 131 can be made smaller than the light-transmitting area of ​​the focusing portion 121, so that the light beam can always maintain the focusing effect during the propagation process.

[0043] Furthermore, in order to better play the role of identification, the shape of the light-transmitting hole 131 can be made consistent with the shape of the switch identification, thereby facilitating visual inspection by the user.

[0044] refer to Figure 2 and Figure 4 The outer cover plate 130 includes a panel 132 and a switch plate 133 which are sequentially arranged in a direction away from the indicator light plate 110. The light-transmitting hole 131 includes a first light-transmitting hole 1321 opened on the panel 132 and a second light-transmitting hole 1331 opened on the switch plate 133. The light-transmitting area of ​​the first light-transmitting hole 1321 is greater than the light-transmitting area of ​​the second light-transmitting hole 1331.

[0045] In the above technical solution, by setting two first light-transmitting holes 1321 and second light-transmitting holes 1331 with different light-transmitting areas, on the one hand, a better light beam convergence effect can be achieved, and on the other hand, a buffering effect can be achieved to prevent the light-transmitting area from changing too much when the light beam is directly transmitted from the focusing portion 121 to the second light-transmitting hole 1331, thereby causing excessive light intensity around the second light-transmitting hole 1331.

[0046] Furthermore, the switch sheet 133 in this embodiment is made of transparent material, and a light-blocking coating is coated on one side of the switch sheet 133 close to the panel 132 . The light-blocking coating can prevent excessive light beams from gathering around the second light-transmitting hole 1331 and affecting the light-transmitting effect.

[0047] It should be noted that the outer side of the switch sheet 133 (i.e., the side away from the lamp bead 111) can be coated with a colored coating to increase the aesthetics, and the specific color can be pink, green, etc. The inner side of the switch sheet 133 (i.e., the side close to the lamp bead 111) is coated with a black light-blocking coating to achieve a light-blocking effect. During the molding process of the switch sheet 133, it can be firstly screen-printed or spray-painted, and then the second light-transmitting hole 1331 in the shape of a switch LOGO can be formed by laser.

[0048] refer to Figure 2 and Figure 5 The indicator light guide structure 100 also includes a fixing frame 140, which is used to install a lamp pole 170. The indicator light board 110 is used to be arranged on a side of the lamp pole 170 away from the fixing frame 140. A supporting portion 122 is formed on the inner cover plate 120, and the supporting portion 122 is used to support the lamp pole 170.

[0049] Specifically, the fixing frame 140 is used to support and fix, and is assisted by the lamp pole 170 to achieve relative positioning of the indicator light panel 110 and the inner cover panel 120 .

[0050] refer to Figure 2 , Figure 3 and Figure 5 In order to further improve the positioning accuracy of the indicator light board 110, a positioning rib 141 can be formed on the fixing frame 140, and a first positioning hole 171 and a second positioning hole 112 are respectively formed on the lamp pole 170 and the indicator light board 110, and the positioning rib 141 is simultaneously accommodated in the first positioning hole 171 and the second positioning hole 112.

[0051] During the assembly process, it is necessary to first move the lamp pole 170 close to the fixing frame 140 so that the positioning rib 141 passes through the first positioning hole 171, and then move the indicator light board 110 close to the lamp pole 170 so that the positioning rib 141 passes through the second positioning hole 112, thereby ensuring the relative position stability of the indicator light board 110, the lamp pole 170 and the fixing frame 140.

[0052] In this embodiment, the cross-sections of the positioning rib 141, the first positioning hole 171 and the second positioning hole 112 are all circular; of course, in other embodiments of the present invention, the cross-sections of the positioning rib 141, the first positioning hole 171 and the second positioning hole 112 can also be rectangular, triangular, prism-shaped, fan-shaped or other shapes, and there is no limitation on their specific cross-sectional shapes.

The fastener 150 is connected to the fastening hole 142 and abuts against a side of the indicator light board 110 away from the lamp pole 170 .

[0054] In the above technical solution, by taking pictures of the matched fastening holes 142 and the fasteners 150 , the indicator light board 110 can be locked to one side of the lamp pole 170 through the fasteners 150 .

[0055] In this embodiment, the fastener 150 can be a bolt, the fastening hole 142 can be a screw hole, the rod of the bolt is threadedly connected to the screw hole, and the bottom surface of the head of the bolt is tightly against the indicator light board 110; of course, in other embodiments of the utility model, the fastening hole 142 can also be a light hole, the fastener 150 can be a light rod with a head structure, the light rod and the light hole have an interference fit, and the head structure is tightly against the indicator light board 110.

[0056] refer to Figure 2 In order to avoid interference with the installation of the fastener 150 and to avoid the welding point connected to the indicator light board 110, a avoidance groove 123 is provided on the side of the inner cover plate 120 close to the indicator light board 110, and one end of the fastener 150 is accommodated in the avoidance groove 123.

[0057] refer to Figure 2 and Figure 5 In order to prevent the indicator light board 110 and the lamp pole 170 from relative deflection during the cooperation with the positioning ribs 141 , the number of the positioning ribs 141 can be at least two, and positioning ribs 141 are provided on both sides of the lamp bead 111 .

[0058] In this embodiment, the number of positioning ribs 141 is on both sides, and the lamp bead 111 is located between the two positioning ribs 141; of course, in other embodiments of the present invention, the number of positioning ribs 141 can also be three, four, five, etc., and multiple positioning ribs 141 can be arranged in multiple rows and columns, and the lamp bead 111 can be located between any two adjacent positioning ribs 141.

[0059] refer to Figure 2 In order to improve the positioning effect of the outer cover plate 130 , the indicator light guide structure 100 may further include a decorative cover 160 , which is sleeved on the outer cover plate 130 .

[0060] Specifically, the decorative cover 160 is a hollow circular ring structure, the inner side of which cooperates with the panel 132 and the switch piece 133 at the same time, and bosses for limiting are formed at both ends of the decorative cover 160, respectively limiting the side where the panel 132 and the switch piece 133 are away from each other, thereby preventing the panel 132 and the switch piece 133 from moving away from each other.

[0061] refer to Figure 1 and Figure 2 The embodiment of the utility model further provides a reading lamp 1000 , including a driving member 300 , a main light source 400 and an indicator light guide structure 100 , wherein the driving member 300 is electrically connected to the main light source 400 and the indicator light board 110 .

[0062] Specifically, the driving member 300, the indicator light panel 110, the inner cover plate 120 and the outer cover plate 130 are all arranged at one end of the lamp pole 170, and the main light source 400 is arranged at the other end of the lamp pole 170. The lamp pole 170 is a hollow structure, and the wiring harness connected between the driving member 300 and the main light source 400 can be accommodated in the hollow inner cavity of the lamp pole 170.

[0065] (1) The indicator light guide structure 100 can generate a light beam through the lamp bead 111, and the focusing portion 121 is supported against the indicator light board 110 and enclosed around the lamp bead 111, thereby avoiding a light leakage gap between the focusing portion 121 and the indicator light board 110, reducing the light beam diverging toward the surrounding, so that most of the light beam can move from the inner side of the focusing portion 121 toward the light-transmitting hole 131 and output, thereby converging the light beam and preventing it from excessively diverging to avoid affecting the indication effect.

[0066] (2) The indicator light guide structure 100 can be provided with two first light-transmitting holes 1321 and second light-transmitting holes 1331 with different light-transmitting areas. On the one hand, it can achieve a better convergence effect on the light beam, and on the other hand, it can play a buffering role to prevent the light beam from being directly transmitted from the focusing portion 121 to the second light-transmitting hole 1331 due to excessive change in the light-transmitting area, thereby preventing the light around the second light-transmitting hole 1331 from being too strong.
