[0031] Embodiment one

[0032] Referring to Figures 1 to 5 As shown in the figure, the embodiment provides an indicator lamp assembly 2, which is used to be installed in a target device housing 1, the housing 1 is provided with a light outlet hole 101, the indicator lamp assembly 2 is installed in the housing 1 through a connecting piece 4, and the indicator lamp assembly 2 is used to conduct the light generated by itself to the outside of the housing 1 through the light outlet hole 101.

[0033] Specifically, the indicator lamp assembly 2 of the embodiment includes a circuit board 21, a light source 22 and a light guide piece 23. The light source 22 is installed on the circuit board 21 and controlled by the circuit board 21, and the related circuit on the circuit board 21 can be used to control the color of the light source 22 and the opening and closing of the light source 22. The light guide piece 23 includes a mounting part 231 and a light guide part 232, the mounting part 231 is configured to be at least partially stacked with the circuit board 21, the connecting piece 4 penetrates the circuit board 21 and the mounting part 231, and extends into the housing 1, thereby fixing the indicator lamp assembly 2 in the housing 1. The light guide part 232 extends towards the light outlet hole 101, and is used to conduct the light emitted by the light source 22 to the outside of the housing 1, the light guide part 232 includes an incident surface 2321 and an exit surface 2323, the light emitted by the light source 22 enters the light guide part 232 through the incident surface 2321, and then exits the light guide part 232 through the exit surface 2323, and is projected to the outside of the housing 1 through the light outlet hole 101, so that it can be observed by the device operator.

[0034] Referring to Figure 2 As shown in the figure, the light guide part 232 of the embodiment further includes a reflecting surface 2322 arranged between the incident surface 2321 and the exit surface 2323 along the light path, the reflecting surface 2322 has a certain included angle with the incident surface 2321, which is used to reflect the light coming from the incident surface 2321 to the exit surface 2323, and then refract the light out of the light guide part 232 through the exit surface 2323.

[0035] Further, the exit surface 2323 and the incident surface 2321 in the embodiment are arranged at an included angle, and the operator adjusts the exit direction of the light at the exit surface 2323 by changing the included angle between the exit surface 2323 and the incident surface 2321.

[0036] Furthermore, in this embodiment, the reflective surface 2322 is a total reflection surface. When the light from the incident surface 2321 shines on the reflective surface 2322, the reflective surface 2322 performs total reflection of the light, avoiding the light from being refracted at the reflective surface 2322 and exiting the light guide part 232.

[0037] In this embodiment, the light rays emitted from the incident surface 2321 only need to undergo one total internal reflection to reach the outside of the housing 1, thus avoiding energy loss of the light rays.

[0038] Reference Figure 2 As shown, in this embodiment, the light guide portion 232 is configured to extend at least partially toward the direction close to the circuit board 21, that is, the light guide portion 232 is configured to have a certain thickness in the arrangement direction of the circuit board 21 and the mounting portion 231, and one side of the circuit board 21 abuts against the light guide portion 232.

[0039] Furthermore, the circuit board 21 is held against the incident surface 2321 of the light guide section 232 along the light emission direction of the light source 22.

[0040] Reference Figures 2 to 5 As shown, in this embodiment, the light source 22 is located on the side of the circuit board 21 away from the mounting portion 231, and the light guide portion 232 extends toward the area close to the circuit board 21 to form an incident surface 2321.

[0041] Reference Figures 2 to 5 As shown, in this embodiment, the light source 22 and the incident surface 2321 are arranged at intervals. After the light source 22 emits light, it causes scattering in the air, which changes the direction of light transmission, so that the light can be directed toward the incident surface 2321 at different angles.

[0042] Therefore, after the light passes through the incident surface 2321 and the light guide 232, it will be directed towards the reflecting surface 2322 at multiple incident angles. The light reflected by the reflecting surface 2322 also has multiple exit angles, so that the light has multiple refraction angles when it exits from the exit surface 2323, thereby causing the light to be scattered into the air.

[0043] In addition, it should be noted that the number of reflective surfaces 2322 in the above embodiments is not a limitation on the inventive concept of this application. The number of reflective surfaces 2322 and the tilt angle relative to the horizontal plane can be arbitrarily set, and can be set according to actual needs.

[0046] Specifically, the light guide part 232 of the light guide 23 comprises an incident surface 2321, two uneven diffuse reflection surfaces 2324 and an exit surface 2323 arranged in sequence along the light path, and the light is incident into the light guide part 232 from the incident surface 2321, repeatedly reflected between the two diffuse reflection surfaces 2324, and finally shot to the exit surface 2323 to be emitted from the light guide part 232 and scattered into the air.

[0047] Further, the light guide part 232 is made of a diffuse reflection material.

[0048] Preferably, the diffuse reflection material can be titanium dioxide.

[0049] In addition, it should be noted that the number of the diffuse reflection surfaces 2324 in the above embodiments is not a limitation of the inventive concept of the present application, and the number of the diffuse reflection surfaces 2324 and the inclination angle relative to the horizontal plane can be arbitrarily set, and can be set according to actual needs.
