擇方案二進行設計。反復觸摸電極片M,燈泡E亮度按“微亮~較亮~最亮~熄滅~微亮……”順序循環(huán)變化。C5隔離安全電容,M為觸摸電極片。電源由VDl、VS、R1和C1組成,通電后在C1兩端可獲得9V左右的直流電壓供集成電路用電。 counting目 錄摘 要 IABSTRACT I1 設計要求及方案選擇 1 1 12 理論分析與設計 2 調(diào)光燈電路的分析及設計 2 調(diào)光燈電路的分析及設計 33 電路設計 4 硬件電路的設計 4 主要元器件介紹 44 系統(tǒng)測試 6 6 6 75 總結(jié) 7參考文獻 91 設計要求及方案選擇要求設計一個小小調(diào)光,采用一個按鍵開關(guān),可以控制小電珠的燈光亮暗,亮暗程度可分若干等級(最多為10個)方案1圖11 觸摸式4擋調(diào)光燈電路原理圖 該電路的核心器件是TT6061A觸摸調(diào)光專用集成電路,它采用CMOS工藝生產(chǎn)制造而成,封裝形式主要為標準DIP一8封裝。關(guān)鍵詞:調(diào)光;LED;計數(shù)ABSTRACTUsing 4017 decimal counting chip, 9013 triode, and create a simple callback ponents such as resistors, light emitting diode light products, realize to adjust the brightness of the light emitting diode. After testing, the system achieved the gear has three adjustable brightness. Can be targeted to meet customer demand, which can be adjusted to the brightness of the lamp, so as to realize save electricity, low carbon life. Incandescent lamp and metal halide lamp is more widely applied in the field of that move light, but with the further promotion of energy conservation and emissions reduction, adjustable LED light after conquering the dimming technical barriers, started to present development trend.Key Words: lig
