Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
The thought of the utility model scheme is to improve the material of original computer state indicator light lampshade, and by control circuit the demonstration of computer state indicator light is controlled.This scheme only needs a computer state indicator light can realize demonstration to the computing machine different conditions.
The structure of active computer status indicator lamp comprises lamp cover 101, light emitting diode 102 and lampshade 103 referring to Fig. 1, and the utility model changes the material of lampshade into the mist luminescent material, and adopts the light emitting diode of high brightness.Because the physical characteristics of mist luminescent material itself, the light transmission that the light emitting diode of high brightness is launched uses the lampshade of this material can produce uniform halation, thereby the illuminated area of enlarging state pilot lamp strengthens indicating effect, also makes the light that sheds softer simultaneously.
A circuit that is used for the state of a control pilot lamp is set, can make status indicator lamp along with the variation of computer mode produces different display effects by this control circuit, this control circuit is a Single Chip Microcomputer (SCM) system, comprises a singlechip chip of realizing control function, provides the crystal oscillator of work clock and some auxiliary capacitors, resistance for single-chip microcomputer.The control principle of this control circuit is the signalisation singlechip chip with computer operation and dormant state, make the state output different control signal of singlechip chip by the program of in singlechip chip, solidifying, utilize this control signal that computer state indicator light is changed along with the variation of computer mode according to computing machine.
This computer state indicator light can be arranged on the main frame of computing machine, also can be arranged on the display, the two principle is identical, just if be arranged on the main frame, then the pin of the external interrupt pin of singlechip chip connection is output terminal pin Sleep Led and the Power Led on the computer motherboard, if be arranged on the display, then be output terminal pin Sleep Led and the Power Led on the display.
An embodiment who is the utility model scheme shown in Figure 2, singlechip chip among this embodiment is the AT89C2051 of MCS51 series, the VCC of this AT89C2051 chip connects 5 volts of power supplys, this power supply can be to be provided by computer power supply, mainboard or display, also can be to obtain GND ground connection by transformation; RSC is connected with the positive pole of resistance R 1 with capacitor C 3, the other end ground connection of resistance R 1, and the negative pole of electrochemical capacitor C3 connects the power supply of computing machine; Capacitor C 1 and C2 one end ground connection, the other end connect the two ends of XT2 and the XT1 port and the crystal oscillator T1 of this AT89C2051 chip respectively; Two external interrupt pin I0.P32 of this AT89C2051 chip and I1.P33 respectively with computer motherboard on two output terminal pin Sleep Led be connected with Power Led; The I/O port of this AT89C2051 chip is connected with the negative pole of light emitting diode L1, and present embodiment specifically is to adopt the A0.P10 port to be connected with the negative pole of light emitting diode L1, and the positive pole of light emitting diode L1 is connected with the positive pole of power supply by resistance R 2.
The AT89C2051 chip can obtain the message of external interrupt according to the variation of Power Led and Sleep Led output level, thereby learn the variation of computer mode, so can design the Single-chip Controlling flow process, make the AT89C2051 chip export different control signals, make computer state indicator light can carry out the state indication according to the variation of computer mode.This control flow is referring to Fig. 3, corresponding following steps:
A1. P10 port output low level after energized makes computer state indicator light be in normal bright state.
The P10 port after energized output low level by setting in advance realization.
A2. detect whether external interrupt is arranged,, illustrate that then computing machine transfers dormant state to, enter step a3 if having, otherwise, step a1 returned.
Computing machine transfers level that dormant state makes Sleep Led pin output to by high step-down by duty, and therefore the I0 that is attached thereto the AT89C2051 chip that connects produces negative edge, thereby has produced external interrupt 0.
A3. control the PWM ripple of P10 port output duty cycle circulation change, make computer state indicator light circulation flicker, and detect whether external interrupt is arranged, if external interrupt is arranged, illustrate that then computing machine goes back to duty again, therefore return step a1, if no, then return step a3.
Computing machine goes back to level that duty makes Power Led pin output by high step-down by dormant state, and therefore the I1 that is attached thereto the AT89C2051 chip that connects produces negative edge, thereby has produced external interrupt 1.
Step a3 is by the PWM ripple of operation breather program realization P10 port output duty cycle circulation change, and the flow process of this breather program may further comprise the steps referring to Fig. 4:
B1.P10 port output one-period and dutycycle are 0 PWM ripple, and start timer T0 and T1, by the PWM wave period and the dutycycle of this two timer control P10 ports output.
B2. the initial value of varying cyclically T1, thus the dutycycle of PWM ripple changed, make P10 can export one-period and fix, and the PWM ripple of dutycycle circulation change.
The dutycycle from 0% to 100% that the initial value of T1 can be configured such that the PWM ripple increases gradually, and then from 100% to 0% reduces gradually.
Because the average current that flows through in the light emitting diode is directly proportional with the dutycycle of PWM ripple, therefore can control in the light emitting diode electric current circulation change regularly by the variation of PWM ripple dutycycle, thereby make light emitting diode can produce the effect of circulation flicker.
After in control circuit, being provided with these two programs, therefore during the computing machine operate as normal, computer state indicator light Chang Liang, again because lampshade can produce uniform halation, what therefore pilot lamp showed is bright, the most maximum circular halation, when computing machine is in dormant state, computer state indicator light from secretly to bright, again from bright to secretly changing, in the brightness circulation change, the halation size is circulation change also, so computer state indicator light has produced the effect of the same flicker that circulates with people's breathing.
This scheme can make computer state indicator light produce different indicating effects by the program of revising in the single-chip microcomputer, and the instruction cycle of single-chip microcomputer be the ms level, therefore can make the variation of pilot lamp seem very soft, level and smooth.
