Detailed description of the invention
For making those skilled in the art be better understood from the technical solution of the utility model, real with concrete below in conjunction with the accompanying drawings
Execute example this utility model is elaborated.
Embodiment in this utility model discloses a kind of LED instruction device, and it is arranged in electronic equipment, Qi Zhong electricity
Subset has shell, photographic head and power supply, photographic head and display lamp and is all located on shell, and display lamp is arranged at photographic head
Side, is more convenient for observing.
The present embodiment by LED instruction device control display lamp in electronic equipment bright, extinguish or flash to show
The low state of charge of battery, battery full state, battery charging state, the state that is turned on and off of photographic head and system start-up
Or closed mode.Wherein electronic equipment includes, but are not limited to notebook computer, panel computer and two-in-one computer.
Specifically, continuing with Fig. 2, the LED instruction device in the present embodiment as a example by being applied to notebook computer,
LED instruction device electrically connects with embedded controller 30 and the power management chip 20 of notebook computer respectively, embedded control
Device 30 processed and power management chip 20 all electrically connect with the CPU10 of notebook computer, are used for controlling the display notes of display lamp correspondence
The duty of the power supply of this computer, photographic head and system, the display lamp in the present embodiment is dual-colored LED lamp 8, and LED indicates
Device includes display lamp, diode and signal input part, and signal input part is used for being electrically connected to dual-colored LED lamp 8 and transmitting control
Signal.Specifically, signal end includes the first end 1 and the second end 2 being connected to embedded controller 30, and is connected to power supply pipe
3rd end 3 of reason chip 20；Diode is arranged on the loop of the second end 2 and/or the 3rd end 3 to dual-colored LED lamp 8.
One section of loop of the first end 1 to dual-colored LED lamp 8 of signal input part is provided with the first resistance 6, and diode is to double-colored
