M379798 五、新型說明： 【新型所屬之技術領域】 本創作係關於一種無線輸入裝置，尤指一種節能的無 線輪入裝置。 【先前技術】 由於個人電腦等科技產品已被廣泛使用，各種新型態 的輸入工具也發展出以便利人們操作這些科技產品。但 是，傳統型的輸入工具，如鍵盤與滑鼠等仍然是最為普遍 被人們所接受的輸入工具。並且，隨著人們對於移動性的 需求，人們再也不想被侷限在一個固定的地方操作電腦等 科技產品，因此各式的無線輸入工具，如無線鍵盤與無線 滑鼠等，以增人們使用這些科技產品的便利性。 這些無線輸入裝置，係利用置入於無線輸入裝置内的 電池以提供運作與無線訊號傳輸所需的電源，這些有限儲 電量的電源，通常會隨著使用者使用的頻率以及操作的方 式，於長短不一的時間内，就會耗盡其儲電量。此時，使 用者就需要進行更換電池，以維持這些無線輸入裝置的正 常運作。甚至，當電源於低電量時，這些無線輸入裝置還 會發生訊號傳輸錯誤或是訊號無法傳輸的問題。這對於使 用者來說會造成極大的困擾。因此，需要針對這些無線輸 入裝置進行有效率的電源損耗控管，以增加使用的時間。 第一圖所示為傳統的無線鍵盤示意圖。 傳統的無線鍵盤10為利用各種無線傳輸的方式進行 訊號的傳輸。當使用者於無線鍵盤10上按下任一個按鍵， 4 M379798 即產生一輸入訊號，則無線鍵盤10即可利用無線傳輸的方 式將使用者所欲輸入的輸入訊號傳輸至一電子設備（如電 腦），以讓使用者能夠進行訊號的輸入或是控制電子裝置的 運作等。另外，於無線鍵盤10的側邊或角落，通常會有複 數個指示燈以顯示鍵盤的設定狀況或是使用狀況，如第一 指示燈 11 ( Num Lock)、第二指示燈 12 ( Caps Lock)、第 三指示燈13 ( Scro 11 Lock)等，甚至會有無線鍵盤10的 電源指示燈（未顯示）、無線連線指示燈（未顯示）、模式 指示燈（未顯示）或是其他的指示燈等。 這些指示燈通常使用發光二極體（LED)做為其光源。 但是，每開啟一個LED就需要3〜5ιηΑ的耗電量，因此，使 用越多的指示燈，例如同時開啟3個指示燈（如第一、第 二及第三指示燈11、12、13)，就需要耗費9〜15mA的耗電 量，更何況於其他設計的無線輸入裝置上，還配置了許多 其他的指示燈或是裝飾燈等，更是加快了電源的消耗。這 對於儲電量不多的電池而言，無疑是雪上加霜，更是大大 地減少使用者使用的時間。於使用者不察覺的情況下或是 追求絢麗的效果的情況下，就大量地增加了電池電量的損 耗，也因此造成使用者需要頻繁地更換電池。 在另一些無線鍵盤的設計當中，取消了這些指示燈（第 一指示燈11、第二指示燈12、第三指示燈13)的設計， 這更會造成使用者於使用上，無法確認無線鍵盤10的設定 狀況或是使用狀況，更是造成使用者使用上的困擾。 【新型内容】 根據本創作之第一實施例提出一種無線輸入裝置，包 5 括.一微處理單元，產生一控制訊號；一脈寬調變單元， =該微處理單元連接，接收該控制訊號，並據以產生一脈 寬調變訊號；一光源控制單元，與該脈宽調變單元連接， 接收该脈寬調變訊號，並據以產生一驅動訊號；以及複數 個指示燈，與該光源控制單元連接，接收該驅動訊號以驅 動該複數個指示燈發光。 根據本創作之第二實施例提出一種無線輸入裝置，包 括.一微處理單元，產生一控制訊號；一光源控制單元， 與該微處理單元連接，接收該控制訊號，並據以產生一驅 動訊號；以及複數個指示燈，與該光源控制單元連接，接 收忒驅動訊號以驅動該複數個指示燈發光；其中，一叶時 單元二與該微處理單元連接，並產生—計時訊號，且該^ 處理單兀根據該計時減控制該光雜制單元停止 驅動訊號。 硪 根據本創作之第三實施例提出一種無線輪入裝置， 括：-微處理單元，產生一控制訊號；一光源控制單元， 與该微處理單7G連接，接收該控制訊號，並據以產生 ?訊號；-發光元件’與該光源控制單元連； 動訊號並據以產生-第m學單元，接收該= 凡件之該第-光束，並據以分光以產生複數個第二光 以及複數個指示燈，各自接收一第二光束。 ， 本案創作人提出本案之創作概念，本創作之機制係盘 ^知技術截然不同，俾以提供具有省電功能之 穿、 置，以促進產業升級。 灼忒 以上之概述與接下來的詳細說明及附圖，皆 進-步說明本創作為達成預定目的所採取之方式、^段= M379798 3式作的其他目的及優點，將在後續的說明 【實施方式】 的模為根據本創作第一實施例之無線輪入裝置 ，據本創作第—實施例之無線輪人裝置2G，具有 處理單元2卜-脈寬調變單元22、—光源 二 及第-指示燈η、第二指示燈12、第三指示燈i:其23中以 於本創作，第-指示燈u為Num LQek指示燈 _ f 12為Caps L〇ck指示燈、第三指示燈13為i i : k燈，且無線輸入裝置2〇為一無線鍵盤。微 21、接收使用者的輪人訊號，並透過—無線模组（未顯 傳运至-電子設備（如電腦）’並且可根據使用者對於 需求，設定’產生-控制訊號。脈寬調變單元以，接收微 處理早兀21之控制訊號’並根據控制訊號產生一脈寬調變 訊號。光源控制單元23接收脈寬調變單元22之脈寬調錄 訊號，並根據脈寬調變訊號產生驅動訊號以驅動第一指J 燈11、第二指示燈12、第三指示燈13發光，豆中，第一 指示燈11、第二指示燈12、第三指示燈13係利用發光二 極體（LED)做為其光源，但是亦可使用其他光源做此 指示燈的光源。 。本創作係利用脈寬調變單元22所產生的脈寬調變訊 號，以控制光源控制單元23驅動第一指示燈u、第二指 不燈12、第三指*燈13進行閃爍發光，以達到節省電源 消耗的目的。脈寬調變單元22可依據微處理單元Μ之設 7 M379798 疋虎產生不同工作週期㈠吻。丫士）比例之脈宽調變 ^號。即是’當使用者選擇“能麟，職處理單元21 ^產生-控制訊號’脈宽調變單& 2 2則根據此控制訊號 上生Λ有奴低工作週期（例如：30%工作週期）之脈寬 調變訊號；當使用者選擇低節能度時，則微處理單元Μ =以產生-控制訊號，脈寬調變單元22則根據此控制訊號 產生-具有較高工作週期（例如：9()%工作週期）之脈宽 調變訊號。統控制單元2 3難據此不^作週期比例之 脈寬調變訊號，以產生不同卫作週期之驅動訊號以驅動第 :指不燈第二指示燈12、第三指示燈13發光。其中， 光源控制單元23所產生之驅動職具有與脈寬調變訊號 相同之工作週期。 ”首脈寬調變單元22產生較高工作週期比例的脈寬調 受訊號’例如：90%工作週期’則表示光源控制單元23 產生具有9 0 %工作週期的驅動訊號以驅動第一指示燈 11、第二指示燈12、第三指示燈13，使得第一指示燈^、 第二指示燈12、第三指示燈13於一工作週期中，9〇%的 時間發光’ 10%的時間不發光。因此，當脈寬調變單元22 產生工作週期為90%的脈寬調變訊號時，光源控制單元23 即可控制第-指示燈H、第二指示燈12、第三指示燈13 具有與直流驅動發光相比10%的節能效果 單元22產生工作週期為簡，第一指示燈;;脈J = 不燈12、第三指TF燈13則具有與直流驅動發光相比鄕 的節能效果。即是，當工作週期比例越低時，其呈有較高 的節能效果，但是其發光亮度也越低。因此’即;^利用^匕 方法，調整無線輸入裝置20之第一指示燈u、第二护示 燈i2」第三指示燈13的耗電程度。 二傳:利用此脈寬調變單 第三指示燈u、:1動這些第―、第二及 第一、第二及笛：社-式’改交為利用脈寬調變驅動 第二才曰示燈11、12、13的驢t 者可根據其節能的 U的駆動方式。則使用 果，並細4二/進仃…以控制進行節能的效 根據“fI# ^裝置2G的電池使用時間。並且， 示㈣；定第:㈣ 同的使用習慣，以述丨At s不且即疋，可針對使用者不 常使用第-指示3/^源，雜。—般來說，使用者最 12 ( Caps Lock指示U=ClU曰不燈）以及第二指示燈 ^ 燈）因此，可將此兩個搀机中认 的工，期比例，即可大幅度地減少能 之』為根據本創作第二實施例之無線輪入裝置 單元ϊΤί置30具有一微處理單元21、-光源控制 二11、第二指示燈12、第三指示燈」 及柄早7C 31。微處理單元 號’並透過-無線模組 使=者，入訊 (如電腦），另m )表傳达至一電子設備 23 ° Ηβ^μ. - ή 生—控制訊號以控制光源控制單元 ί十U 31 _^單元21連接，於本實施例中， h早το 31 δ又置於微處理單元21内，並 時:即是，當使用者輸人η 訊號，υ時單，士直至使用者輸入下一個輸人 一叶時訊舻。# w不叶^間到一預定時間時，即產生 十⑶虎先源控制單元23 ’接收微處理單元21之控 M379798 制广虎,據以產生—驅動訊號以驅動第一指示燈"、第 一 4曰不燈I 2、第三指示押丨q、仓, 且3進仃發光，其中第一指示燈 利用丨η、第三指示燈Μ指示燈於本實施例係 作^其光源，但是亦可為其他種類的發光光源。 Μ ^來W ’使用者並非永遠制使用如第—圖所示之 無線鍵盤10，使用者可能於一俨. 备進行欣當雷…： 持績使用操作後，即 :進订h電衫、_、思考或是離料。但是，於這些 f桑作無線鍵盤10的時間内，傳統的無線鍵盤10的第二 ί不f 11、第二指示燈12、第三指示燈13仍然會持續發 光以提不使用者無線鍵盤1G的設錄態，當然，第一指示 日、第二指不燈12、第三指示燈13亦會持續消耗電源。 =二疋，若是使用者忘記關閉無線鐽盤1〇的開關，則於離 ^後-段較長時間，第—指示燈u、第二指示燈12、第三 指不燈13即會消耗光所有電池的儲電量。亦即，當使用者 於離開一段較長時間後’無線鍵盤1 〇的電池儲電量即會被 消耗殆盡’而使用者則必須重新更換電池才能夠重^使 用因此，本創作第二實施例之無線輸入裝置3〇即可自動 偵測使用者的使用狀況，於使用者—段時間未使用 動，閉第-指示燈U、第二指示燈12、第三指示燈13， 以節省電源的消耗。 根據本創作第二實施例’無線輸入裝置3〇之微處理單 =21產生一控制訊號’光源控制單元23接收此控制訊號， 亚據以產生一驅動訊號以驅動第一指示燈U、第二指示^ 12、第三指示燈13發光’此時為一正常使用模式。4 = ^ 者於無線輸入裝置30之-正常使用模式下輸入—輸入訊 唬，則微處理單元21接收此輸入訊號，並透過一無線模組 M379798 (未顯示）傳送此輸入訊號至一電子 叶未再讀人—輸人訊號，則計時單元31則產生一 二==元I則根據此計時訊號，控制^控 指示燈12、第三指示燈13即停止弟二 3〇進入-休叫直至，使用者;^無:輪入裝置 則微處理單元2〗即產生n 入如虎’ ，-驅動訊號，以重新二以源元 义且12、4三指示燈13發光，並恢復至正常使用模式。曰不 3〇 ^ ㈣:第第二指示 二=入任一個輸入訊號，則微處=二 指生示燈ίι ΤΓ以回復至正常使用模式，並恢復第」 二2、第三指示燈13以顯示無線輸 =外’本實施例亦可具有一指示燈開關32，以讓使用 ίί=^Γ號’則微處理單元21可據以控制光源控制 可自由設定第一指示 ㈣無以燈13的開啟或關閉，以 的控==根據本創作第二實施例之無爾置 根據本創作第二實施例之無绩輸入裝置別，使用者須 先開啟無線輸入裝置30,如步驟S10所示 示，32設定第-指示燈U、第二指示燈12 Π:: 不垃13的開啟或是闕閉，如步驟s】 者』M379798 V. New description: [New technical field] This creation is about a wireless input device, especially an energy-saving wireless wheel-in device. [Prior Art] Since technology products such as personal computers have been widely used, various new types of input tools have been developed to facilitate the operation of these technology products. However, traditional input tools such as keyboards and mice are still the most commonly accepted input tools. Moreover, with the demand for mobility, people no longer want to be limited to a fixed place to operate computers and other technology products, so various wireless input tools, such as wireless keyboards and wireless mice, to increase people's use of these The convenience of technology products. These wireless input devices utilize a battery placed in the wireless input device to provide power for operation and wireless signal transmission. These limited power storage power sources are usually used according to the frequency and operation mode of the user. In a short period of time, it will deplete its power storage. At this point, the user will need to replace the battery to maintain proper operation of these wireless input devices. Even when the power is low, these wireless input devices may have a problem of signal transmission errors or signals cannot be transmitted. This can be extremely confusing for the user. Therefore, efficient power loss control is required for these wireless input devices to increase the time of use. The first figure shows a schematic diagram of a traditional wireless keyboard. The conventional wireless keyboard 10 transmits signals by means of various wireless transmissions. When the user presses any button on the wireless keyboard 10 and the 4 M379798 generates an input signal, the wireless keyboard 10 can transmit the input signal desired by the user to an electronic device (such as a computer) by wireless transmission. ) to allow the user to input signals or control the operation of the electronic device. In addition, on the side or corner of the wireless keyboard 10, there are usually a plurality of indicators to indicate the setting status or usage status of the keyboard, such as the first indicator light 11 (Num Lock) and the second indicator light 12 (Caps Lock). , the third indicator light 13 (Scro 11 Lock), etc., even the wireless keyboard 10 power indicator (not shown), wireless connection indicator (not shown), mode indicator (not shown) or other indications Lights, etc. These indicators typically use a light-emitting diode (LED) as their source. However, every time you turn on an LED, you need 3~5ιηΑ of power consumption. Therefore, the more indicators are used, for example, three indicators (such as the first, second, and third indicators 11, 12, 13) are turned on at the same time. It takes 9 to 15 mA of power consumption, not to mention the other wireless input devices, and many other indicators or decorative lights, which speed up the power consumption. This is undoubtedly worse for batteries that don't store a lot of electricity, and it greatly reduces the time users spend. In the case where the user does not notice or pursues a brilliant effect, the battery power is greatly increased, and the user needs to frequently replace the battery. In the design of other wireless keyboards, the design of these indicators (the first indicator 11, the second indicator 12, and the third indicator 13) is cancelled, which may cause the user to use the wireless keyboard. The setting status or usage status of 10 is even more troublesome for users.

The creator of the case proposed the concept of creation of this case. The mechanism of this creation is different from that of the technology, so as to provide a power-saving function to promote industrial upgrading. The above summary and the following detailed description and accompanying drawings are all steps to illustrate the other ways and advantages of this creation for the purpose of achieving the intended purpose, paragraph = M379798 3, which will be explained in the following [ The wireless wheeling device according to the first embodiment of the present invention has a processing unit 2, a pulse width modulation unit 22, a light source 2, and a wireless wheeling device according to the first embodiment of the present invention. The first indicator light η, the second indicator light 12, and the third indicator light i: in the 23rd, the first indicator light u is the Num LQek indicator _ f 12 is the Caps L〇ck indicator, the third indication Lamp 13 is an ii: k lamp and wireless input device 2 is a wireless keyboard. Micro 21, receiving the user's wheel signal, and through the - wireless module (not shown to - electronic devices (such as computers)' and can set the 'generating-control signal' according to the user's demand. Pulse width modulation The unit receives the control signal of the microprocessor 21 and generates a pulse width modulation signal according to the control signal. The light source control unit 23 receives the pulse width modulation signal of the pulse width modulation unit 22, and adjusts the signal according to the pulse width modulation signal. A driving signal is generated to drive the first finger J lamp 11, the second indicator light 12, and the third indicator light 13 to emit light, and the first indicator light 11, the second indicator light 12, and the third indicator light 13 are used in the bean. The body (LED) is used as the light source, but other light sources can also be used as the light source of the indicator light. The creation uses the pulse width modulation signal generated by the pulse width modulation unit 22 to control the light source control unit 23 to drive the first An indicator light u, a second indicator light 12, and a third finger light 13 perform flashing illumination to save power consumption. The pulse width modulation unit 22 can be different according to the setting of the micro processing unit 7 M379798 Work cycle (a) kiss. Disabilities) ratio of the PWM ^ number. That is, when the user selects "Energy, the processing unit 21 ^ generates - control signal ' pulse width modulation list & 2 2 according to this control signal has a slave low duty cycle (for example: 30% duty cycle) The pulse width modulation signal; when the user selects low power consumption, the micro processing unit Μ = generates a control signal, and the pulse width modulation unit 22 generates according to the control signal - having a high duty cycle (for example: The pulse width modulation signal of 9 ()% duty cycle). The control unit 2 3 is difficult to use the pulse width modulation signal of the cycle ratio to generate the driving signals of different guard cycles to drive the first: The second indicator light 12 and the third indicator light 13 emit light, wherein the driving position generated by the light source control unit 23 has the same duty cycle as the pulse width modulation signal. The first pulse width modulation unit 22 generates a higher duty cycle ratio. The pulse width adjustment signal 'for example: 90% duty cycle' indicates that the light source control unit 23 generates a driving signal having a 90% duty cycle to drive the first indicator light 11, the second indicator light 12, and the third indicator light 13, Make the first indicator ^, second Lamp 12, the third indicator 13 in a working cycle, the light emitting time 9〇% '10% of the time does not emit light. Therefore, when the pulse width modulation unit 22 generates a pulse width modulation signal with a duty cycle of 90%, the light source control unit 23 can control the first indicator light H, the second indicator light 12, and the third indicator light 13 to have a direct current Compared with the 10% energy-saving effect unit 22, the driving illumination is simple, the first indicator light; the pulse J=no-light 12, and the third-finger TF lamp 13 have an energy-saving effect compared with the direct-current driving illumination. That is, when the duty cycle ratio is lower, it exhibits a higher energy saving effect, but the luminance thereof is also lower. Therefore, the power consumption of the first indicator light u and the second indicator light i2" of the wireless input device 20 is adjusted by the method. Second pass: use this pulse width to change the single third indicator u,: 1 move these first, second and first, second and flute: social-style 'replacement to use pulse width modulation to drive the second The 驴t of the lights 11, 12, 13 can be based on the swaying mode of the energy-saving U.
