New description: [New technical field] This creation involves a warning device that is installed on a cooling fan to sense whether the temperature of the cooling fan circuit is abnormal. [Prior Art] The CPU (central processing unit) and various Ic chips installed in the host computer generate heat (collectively called heat source) during operation, and this heat must be removed in time to avoid high temperature on the CPU and 1C chip. Damage is caused. Therefore, where a cpu or 1C chip is placed on the motherboard, a cooling fan that directly discharges heat is usually provided. In addition, the heat generated from the CPU or 1C chip will remain in the casing of the computer mainframe. Therefore, an additional cooling fan must be installed at the appropriate position of the machine (4) to extract the heat from the casing. The above-mentioned political heat fan only provides a simple heat-discharging function, and does not provide a singularity function. Therefore, when the cooling fan fails or the temperature of the circuit is increased, the electronic component is easily caused by the lack of warning. burn. The current computer system has an over-temperature protector through an embedded controller (_EC) on the motherboard. The embedded control benefits the temperature of the battery system, and according to the output pulse width modulation (10) width mGdulation, PWM) signal, and then controls the speed of the system touch system with the pulse width and low signal, Dalong The effect of the temperature. Of course, such a super 'plate insurance. In another way, because it is designed as a feedback ((9) this fine) system, the M432073 operation is performed, so that the embedded controller must correspond to the output pulse width modulation signal according to the feedback temperature detection result. On the other hand, this over-temperature protection method is usually combined with a preset threshold of multiple temperatures for segmentation control, so that the embedded controller must respond to the output pulse width modulation signal according to different temperature segments. Therefore, the response of this over-temperature protection method is not fast enough and sensitive. The cooling fan control circuit provided by Taiwan Patent No. 1,354,494 is to solve the problem of the conventional embedded controller described above, which can determine whether to cut φ to manually adjust the pulse wave of the pulse width modulation signal according to the ambient temperature. Width, and then adjust the speed of the cooling fan with the adjusted pulse width modulation signal. However, manually adjusting the pulse width is not only inflexible to react to temperature changes' and is also inconvenient to use. [New content] The purpose of this creation is to solve the problem that the conventional cooling fan only has a simple heat-discharging function φ without overheat warning function; and the Taiwan η53· patent case can be switched to manually adjust the pulse width to control The speed of the cooling fan is not only incapable of reacting to changes in temperature, but also inconvenient to use. The ship of the present invention is provided with at least a light-emitting unit and a temperature detecting circuit. The temperature detecting circuit is electrically connected to the light-emitting unit. When the temperature of the circuit is measured, the temperature rises to a specific operation. The temperature_circuit drives the light-emitting unit to emit light. The light-emitting unit finds light that can emit a color that is not colored to provide a warning that the user's cooling fan is in a normal use state or an overheated state. 4 tearing means of the present invention, comprising: a fan drawing, at least - a lighting unit and a temperature side circuit; the lighting unit and the temperature _! circuit are in contact with the fan body ' and the temperature side circuit is connected to the lighting unit, # The temperature detecting circuit drives the light emitting unit to emit light when the temperature of the temperature side to the circuit rises to a specific value. The hairline of the work may include a first light source, a first light source, a first light source, and a temperature gamma circuit, and the first transistor having a "thermistor...connected" source. And a second transistor connected to the second light source. When the circuit is at a normal temperature, the first transistor is not turned on to make the first light source not emit light, but the second transistor is turned on to cause the second light source to emit light. When the temperature of the circuit rises, the resistance of the thermistor is lowered, so that the first transistor is turned on, so that the first source emits light but the second transistor does not conduct, so that the second light source does not emit light. . Based on the long service life and power saving considerations, the light source uses a light-emitting diode (LED). In order to enable the light source to see the light source in multiple orientations, the present invention can set a complex array of light-emitting units in the fan body. . In order to allow the user to clearly distinguish whether the cooling fan is in normal temperature operation or overheating operation (4) 'This creation can produce red light (4) as the first light source, and the LED capable of generating peak light as The second light source. The temperature side of this creation can be called the surface of the county to make the power supply. Therefore, when the thief secret _ can not discharge the heat, the temperature of the cooling fan can be used to (4) act to make the source flow abnormal. At high temperatures, the illuminating warning. This creation has the heat dissipation of the display device. In addition to the chassis providing LeBron ^ Tian Bing, _ computer, motherboard recovery: for heat release, it can also be applied to power supply cards and other devices that require heat dissipation or device.
