Description

Status Indicator

technical field

The present invention relates to a status indicator light, and in particular to a status indicator light suitable for electronic devices.

Background technique

Generally speaking, the electronic device usually has a status indicator light exposed from the casing, so that the user can understand the operation status of the electronic device. For example, in a general computer host or server, there is usually a status indicator next to the network interface to indicate the current network connection status and network transmission status. In addition, the status indicator light can be used to indicate the operating status of the computer's hard disk, CD-ROM or other devices.

The existing status indicator usually has a plurality of interconnected light guide bars and a plurality of light sources respectively corresponding to the light guide bars, wherein the light guide bars are exposed from the housing of the electronic device to transmit the light emitted by the light sources to the outside. However, the light guide rods of the status indicators are usually connected to the same base, so that the light emitted by each light source will be transmitted to other non-corresponding light guide rods through the base body. This phenomenon will cause the light guide bar exposed on the housing of the electronic device to emit wrong indicator light, causing troubles to users.

Detailed ways

FIG. 1 is a top view of a status indicator light according to an embodiment of the present invention. FIG. 2 is a perspective view of the light guide structure in FIG. 1 . Please refer to FIG. 1 and FIG. 2 , the status indicator light 100 of this embodiment is suitable for an electronic device 50 . The status indicator light 100 includes a light guide structure 110 and at least two light sources 120 (three are shown). The light guide structure 110 includes a base 112 , at least two light guide columns 114 (three are shown) and at least one light blocking layer 116 (two are shown). In this embodiment, the electronic device 50 is, for example, a server, and the status indicator light 100 is, for example, disposed next to the network interface of the server to indicate the network connection status and network transmission status.

The seat body 112 is disposed in the electronic device 50, and has at least two transparent parts 112a (shown as three) and at least one arched part 112b (shown as two) connected between adjacent transparent parts 112a. ), wherein the two ends of each arched portion 112b are respectively connected to the two adjacent light-transmitting portions 112a. The light guide rods 114 are respectively connected to the light-transmitting portion 112a and extend toward the extension direction of the arched portion 112b , wherein the electronic device 50 exposes one end of each light guide rod 114 . The light blocking layer 130 is disposed on an inner surface S of the arch portion 112b. The light sources 120 are disposed on the base body 112 and respectively correspond to the transparent portions 112a, wherein each light source 120 is used to emit light passing through the corresponding transparent portion 112a and the corresponding light guide rod 114 for status indication.

It is worth noting that each light-shielding layer 116 has a light-shielding effect, and can prevent the light emitted by the light sources 120 on both sides of the corresponding arched portion 112 b from being transmitted to the non-corresponding light-transmitting portion 112 a and the light guide column 114 . Specifically, when one of the light sources 120 emits light according to the operation of the electronic device 50 and the other light source 120 does not emit light according to the operation of the electronic device 50 , the arched portion between the two light sources 120 The light blocking layer 116 on the inner side of 112b can block the light emitted by one of the light sources 120, preventing it from being transmitted to the light-transmitting portion 112a and the light guide bar 114 corresponding to the other unlit light source 120 to generate wrong status indicating light.
