此時，副光源22之第二發光二極體LED2-LED7 處於辅助照明狀態，而是否需要進行辅助照明則由 光電三極體K1控制。具體控制過程為：1 )光電三 極體K1受光弱時，光電三極體K1等同於斷路，電 阻R6接至第一直流電壓8的正極，處於高邏輯狀態 使三極體Q3導通，由第一直流電壓8給副光源22 之第二發光二極體LED2-LED7供電，進行輔助照 明；2)光電三極體K1受光強時，光電三極體K1 等同於短路，三極體Q3的基極被短接至地，三極體 Q3不能導通，第一直流電壓8不給副光源22之第 二發光二極體LED2-LED7供電，副光源LED2-LED7 不進行辅助照明。 如果在停電之應急狀況下，第一直流電壓8與 第二直流電壓9均無輸出，蓄電池BT不再充電， 三極體Q3不導通，主光源21之第一發光二極體LED 不亮。由於電容Cl已經儲電，經電阻R3放電使三 極體Q2導通，且二極體D3經電阻R2和三極體Q2 接至地，三極體Q1的基極電壓拉低，使三極體Q1 導通，電池BT經三極體Q1給副光源22之第二發 光二極體LED2-LED7供電使其發光，穩壓二極體 Z1中電流持續向電容C1充電，並維持使三極體Q2 導通，故電池BT能經三極體Q1持續放電。 此時，副光源22之第二發光二極體LED2-LED7 18 201113464 處於應急照明狀態，而是否需要進行應急照明則由 光電三極體K2控制。具體控制過程為：i)如光電 三極體K2受光弱，光電三極體K2等同斷路，三極 體Q2工作狀態不受影響’副光源22之第二發光二 極體LED2-LED7由蓄電池BT供電進行應急照明； 2)如光電三極體K2因受光強而導通時，三極體q] 的基極被拉至地’電容C1被放電，三極體Q2截止， 並使三極體Q1截止，故蓄電池BT不給副光源22 之第*一發光一極體LED2-LED7供電，副光源22之 第二發光二極體LED2-LED7不進行應急照明。 由上述的實施方式已進一步清楚說明本發明的 技術特徵及達成之功效，包括： 1) 本發明供一種能控制普通照明、辅助照明 及應急照明的發光二極體燈具，藉由在控制電路中 的轉換控制電路，當通電時，主光源發光照明，副 光源可經控制在環境亮度低時進行辅助照明補光，

The base of the triode Q1 is connected to the one body D1 through the diode D3. Under the high voltage logic of the cathode of the diode D3, the emitter and the base of the polar body q! cannot be biased and turned on, so the pole The emitter Q2 of the body Q2 and the collector are not conducting, the battery BT cannot discharge the second light-emitting diode led2 led7 of the secondary light source 22, and the diode D2 is charged by the resistors R1 and R4 to charge the capacitor C1. 17 201113464 At this time, the second light-emitting diodes LED2-LED7 of the sub-light source 22 are in an auxiliary illumination state, and whether or not auxiliary illumination is required is controlled by the phototransistor K1.

A DC voltage 8 supplies power to the second LEDs LED2-LED7 of the sub-light source 22 for auxiliary illumination; 2) When the phototransistor K1 receives light, the phototransistor K1 is equivalent to a short circuit, and the base of the triode Q3 The pole is shorted to ground, the triode Q3 cannot be turned on, the first direct current voltage 8 does not supply power to the second light emitting diode LED2-LED7 of the auxiliary light source 22, and the auxiliary light source LED2-LED7 does not perform auxiliary illumination. If there is no output of the first DC voltage 8 and the second DC voltage 9 in the emergency situation of power failure, the battery BT is no longer charged, the triode Q3 is not turned on, and the first LED of the main light source 21 is not illuminated.

Turned on, so the battery BT can continue to discharge through the triode Q1. At this time, the second light-emitting diodes LED2-LED7 18 201113464 of the secondary light source 22 are in an emergency lighting state, and whether emergency lighting is required is controlled by the photoelectric triode K2. The specific control process is: i) If the phototransistor K2 is weak, the phototransistor K2 is equivalent to the open circuit, and the triode Q2 is not affected. The second light-emitting diode of the sub-light source 22 is LED2-LED7 by the battery BT. Power supply for emergency lighting; 2) If the phototransistor K2 is turned on due to the light intensity, the base of the triode q] is pulled to the ground. Capacitor C1 is discharged, the triode Q2 is turned off, and the triode Q1 is turned off. As a result, the battery BT does not supply power to the first light-emitting diode LED2-LED7 of the sub-light source 22, and the second light-emitting diode LED2-LED7 of the sub-light source 22 does not perform emergency lighting.
