Embodiment Construction

[0020] image 3 It is a schematic diagram of a multi-disk system. Please refer to image 3 , the multi-hard disk system 300 includes hard disk groups 320 and 340, which can be composed of, for example, figure 1 Controlled by different boards in the Each hard disk group has different indicator lights, such as 321 and 341, which are used to display the status of the respective hard disk group. In this embodiment, the display lights 321 and 341 can be realized by light-emitting components such as light-emitting diodes.

[0021] Figure 4 Shown is a circuit diagram of a light signal module according to a preferred embodiment of the present invention. Please refer to Figure 4 , the light signal module 400 of this embodiment can be applied to, for example image 3 The disclosed multi-disk system 300. In the light signal module 400 , it at least includes a first light-emitting component 421 , and the first light-emitting component 421 may be the display light 321 or 341 in t...

Abstract

The invention discloses a control circuit for a hard disk light signal. The hard disk light signal is generated by a first luminous component. The control circuit for the hard disk light signal comprises a first diode and a first switch. The cathode terminal of the first diode receives a first control signal. Moreover, the first switch is coupled to the anode terminal of the first diode and is used for determining whether to conduct a power supply to the first luminous component according to the state of the anode terminal of the first diode so as to generate the hard disk light signal.

Description

technical field [0001] The present invention relates to a control circuit of a hard disk light signal, and in particular to a control circuit of a hard disk light signal module. Background technique [0002] figure 1 Shown as a server system diagram with multiple motherboards. Please refer to figure 1 , in some server systems, such as the server system 100, there are multiple motherboards 121, 122, 123 and 124. In the server system 100 , a plurality of power supplies 111 , 112 are also configured to supply the power required for operation of the motherboards 121 , 122 , 123 and 124 . Wherein, the power supply 111 is used to supply the power required by the motherboards 121 and 122 , and the power supply 112 is used to supply the required power of the motherboards 123 and 124 . [0003] In addition, a plurality of hard disks are also arranged in the server system 100 . And these hard disks can be equipped with indicator lights, which can be lit when the hard disk is acti...
