請參考圖1及圖2,本發明筆記型電腦100包括鍵盤部分10及監視器部分20,該鍵盤部分10與監視器部分20是透過轉軸30連接在一起的,以上部分為習知技術,這裡就不具體說明。其中,在圖1的第一較佳實施方式中,該鍵盤部分10的最上部的中間位置處,也就是靠近該轉軸30的部分設有一長條形的光源40,在圖2的第二較佳實施方式中,該監視器部分20的最下部的中間位置處,也是靠近該轉軸30的部分設有該長條形的光源40。之所以將光源40設置在該鍵盤部分10的最上部或監視器部分20的最下部的中間位置處,是為了提高該光源40的照明效果,以使用戶可方便在較暗 處使用該鍵盤部分10。 Referring to FIG. 1 and FIG. 2, the notebook computer 100 of the present invention includes a keyboard portion 10 and a monitor portion 20, and the keyboard portion 10 and the monitor portion 20 are connected through a rotating shaft 30. The above part is a prior art, here It is not specified. Wherein, in the first preferred embodiment of FIG. 1, an intermediate portion of the uppermost portion of the keyboard portion 10, that is, a portion adjacent to the rotating shaft 30, is provided with an elongated light source 40, which is the second in FIG. In a preferred embodiment, the elongated light source 40 is disposed at a portion of the lowermost intermediate portion of the monitor portion 20 that is also adjacent to the rotating shaft 30. The light source 40 is disposed at the uppermost portion of the keyboard portion 10 or at the lowermost intermediate position of the monitor portion 20 in order to improve the illumination effect of the light source 40 so that the user can conveniently be darker. This keyboard portion 10 is used.
其中,上述實施方式中的光源40為一發光二極體,其他實施方式也可選用其他類型的光源。該第一與第二較佳實施方式的區別僅在於該光源40的設置位置不同,其他部分則均相同,其他實施方式也可同時在該鍵盤部分10的最上部及該監視器部分20的最下部的中間位置處設置兩個光源40,以使照明效果更好,具體可根據實際需要進行設計。 The light source 40 in the above embodiment is a light emitting diode, and other types of light sources may be selected in other embodiments. The difference between the first and second preferred embodiments is only that the position of the light source 40 is different, and other parts are the same. Other embodiments may also be at the uppermost portion of the keyboard portion 10 and the most of the monitor portion 20 at the same time. Two light sources 40 are disposed at the lower intermediate position to make the lighting effect better, and the design can be designed according to actual needs.
請參考圖3,本發明還提供一用於控制該光源40的光源控制電路50,該光源控制電路50包括該光源40、四個電阻R1-R4、三個NPN型電晶體Q1-Q3。其他實施方式中,該NPN型電晶體Q1-Q3也可選用其他類型的電子開關,如場效應電晶體等。 Referring to FIG. 3, the present invention further provides a light source control circuit 50 for controlling the light source 40. The light source control circuit 50 includes the light source 40, four resistors R1-R4, and three NPN-type transistors Q1-Q3. In other embodiments, the NPN type transistors Q1-Q3 may also be selected from other types of electronic switches, such as field effect transistors.
該電阻R1的第一端連接至筆記型電腦100內部的一工作電壓端3D3V,該工作電壓端3D3V在筆記型電腦100處於工作狀態時提供電壓(如3.3V),在筆記型電腦100處於休眠狀態時不提供電壓。該電阻R1的第二端連接至電晶體Q1的基極,該電晶體Q1的射極接地,集極連接至該光源40的陰極及該電晶體Q3的集極。該光源40的陽極透過該電阻R3連接至筆記型電腦100內部的備用電壓端5V_DUAL,該備用電壓備用電壓端5V_DUAL在筆記型電腦100處於工作狀態及休眠狀態時均提供電壓(如5V)。該電阻R2的第一端連接至筆記型電腦100的一睡眠訊號端S3_sleep#,該睡眠訊號端S3_sleep#在筆記型電腦100處於工作狀態時始終保持高電平狀態,在筆記型電腦100處於休眠狀態時提供一由高低電平組成的方波訊號。該電阻R2的第二端連接至該電晶體Q2的基極,該電晶體Q2的射極接地,集極透過該電阻R4連接至該備用電壓端5V_DUAL 。該電晶體Q3的射極接地,基極連接至該電晶體Q2的集極。 The first end of the resistor R1 is connected to a working voltage terminal 3D3V inside the notebook computer 100, and the working voltage terminal 3D3V provides a voltage (such as 3.3V) when the notebook computer 100 is in an operating state, and is in a sleep state in the notebook computer 100. No voltage is supplied in the state. The second end of the resistor R1 is coupled to the base of the transistor Q1, the emitter of the transistor Q1 is grounded, and the collector is coupled to the cathode of the source 40 and the collector of the transistor Q3. The anode of the light source 40 is connected to the standby voltage terminal 5V_DUAL inside the notebook computer 100 through the resistor R3. The standby voltage standby voltage terminal 5V_DUAL provides a voltage (for example, 5V) when the notebook computer 100 is in an active state and a sleep state. The first end of the resistor R2 is connected to a sleep signal terminal S3_sleep# of the notebook computer 100, and the sleep signal terminal S3_sleep# is always in a high state when the notebook computer 100 is in an active state, and is in a sleep state in the notebook computer 100. The state provides a square wave signal composed of high and low levels. The second end of the resistor R2 is connected to the base of the transistor Q2, the emitter of the transistor Q2 is grounded, and the collector is connected to the standby voltage terminal 5V_DUAL through the resistor R4. . The emitter of the transistor Q3 is grounded and the base is connected to the collector of the transistor Q2.
工作時,若筆記型電腦100處於工作狀態,由於該備用電壓端5V_DUAL及該工作電壓端3D3V均提供電壓,則該電晶體Q1始終保持導通狀態,故而該光源40始終處於接通電源的狀態,即該光源40始終發光,此時該光源40除了具有指示筆記型電腦100處於工作狀態的功能外,由於其設置於該鍵盤部分10的最上部或監視器部分20的最下部的中間位置處,故可同時對該鍵盤部分10提供照明用的光線,以使用戶在光線較暗的地方也能方便的進行鍵盤操作。 During operation, if the notebook computer 100 is in an active state, since the standby voltage terminal 5V_DUAL and the working voltage terminal 3D3V are both supplied with voltage, the transistor Q1 is always kept in an on state, and thus the light source 40 is always in a power-on state. That is, the light source 40 is always illuminated. At this time, the light source 40 has a function of indicating that the notebook computer 100 is in an operating state, and since it is disposed at the uppermost portion of the keyboard portion 10 or at the lowermost intermediate position of the monitor portion 20, Therefore, the keyboard portion 10 can be provided with illumination light at the same time, so that the user can conveniently perform keyboard operation in a place with low light.
若筆記型電腦100處於休眠狀態時,該工作電壓端3D3V不提供電壓,則該電晶體Q1始終保持截止狀態,由於該睡眠訊號端S3_sleep#在筆記型電腦100處於休眠狀態時提供一由高低電平組成的方波訊號,則在該睡眠訊號端S3_sleep#為高電平時,該電晶體Q2導通,而該電晶體Q3截止,進而該光源40不發光,而在該睡眠訊號端S3_sleep#為低電平時,該電晶體Q2截止,而該電晶體Q3導通,進而該光源40發光。又由於該睡眠訊號端S3_sleep#為方波訊號,則筆記型電腦100處於休眠狀態時該光源40為閃爍狀態,進而指示筆記型電腦100處於休眠狀態。 If the notebook computer 100 is in the sleep state, the working voltage terminal 3D3V does not provide a voltage, the transistor Q1 is always kept off, because the sleep signal terminal S3_sleep# provides a high and low voltage when the notebook computer 100 is in the sleep state. When the sleep signal terminal S3_sleep# is at a high level, the transistor Q2 is turned on, and the transistor Q3 is turned off, and the light source 40 does not emit light, and the sleep signal terminal S3_sleep# is low. At the level, the transistor Q2 is turned off, and the transistor Q3 is turned on, and the light source 40 is illuminated. Moreover, since the sleep signal terminal S3_sleep# is a square wave signal, the light source 40 is in a blinking state when the notebook computer 100 is in a sleep state, thereby instructing the notebook computer 100 to be in a sleep state.
本發明筆記型電腦100所設計的光源40不僅可以用來指示筆記型電腦100的工作狀態,還由於該光源40設置在了該鍵盤部分10的最上部或監視器部分20的最下部的中間位置處,故還可在光線較暗時為鍵盤部分10提供照明用的光線,使其更具人性化。 The light source 40 designed by the notebook computer 100 of the present invention can be used not only to indicate the operating state of the notebook computer 100, but also because the light source 40 is disposed at the uppermost portion of the keyboard portion 10 or at the lowermost intermediate position of the monitor portion 20. Therefore, it is also possible to provide illumination for the keyboard portion 10 when the light is dim, making it more user-friendly.
