Description of drawings:
Fig. 1 is the schematic appearance of embodiment, and Fig. 2 is the electrical schematic diagram of embodiment.
Among the figure, 1, handle 2, lamp box 3, reflector.
Embodiment:
Embodiment, a kind of high brightness emergency light.
With reference to Fig. 1, Fig. 2, this high brightness emergency light is made of step-down rectifying circuit, indicating circuit, current-limiting circuit, switching circuit, inverter oscillation device, step-up transformer B2, storage battery E and protective circuit thereof and fluorescent tube RL.Step-down rectifying circuit is made of transformer B1 and bridge rectifier D 1-D4; indicating circuit is made of pressure limiting resistance R 1 and LED (indicator light); current-limiting circuit is made of resistance R 2 and diode D5; the output of current-limiting circuit connects the input of protective circuit; two outputs of protective circuit are just connecting storage battery E; negative pole; storage battery E adopts lithium-ions battery; the positive pole of battery is connected by the input of switching circuit with the inversion oscillator; switching circuit comprises electronic switch K1 and hand switch K2, and electronic switch K1 is made of electromagnetic relay J and diode D6.The inversion oscillator is made of capacitor C 4, resistance R 3 and high power transistor VT1, resistance R 3 and capacitor C 4 backs in parallel one end are connected in the base stage of transistor VT1, are connected in the positive pole of battery behind the filament of other end connection fluorescent tube one end and the input coil L2 of step-up transformer B2.The output of inversion oscillator is connected with the input coil L1 of step-up transformer B2, and the output winding L3 of step-up transformer connects fluorescent tube RL, and fluorescent tube RL adopts 16W 2D type trichromatic fluorescent light tube, and its light efficiency that sends is equivalent to 85W scalding lamp.
Basic functional principle: when should anxious lamp connecting electric main; the 220V civil power is reduced to low-voltage AC through transformer B1; become low-voltage DC through the sub-D1-D4 rectification of bridge rectifier; behind current-limiting resistance R2 and unilateral diode D5, enter the input of protective circuit again; electric current charges to battery E from the output output of protective circuit again; when electric weight is charged to the set upper limit value; protective circuit can be cut off charge power supply automatically; when battery discharge to the regulation lower limit the time; protective circuit also can be cut off supply current automatically, thereby protects storage battery effectively.Protective circuit Shenzhen magnificent company of shaking is on sale.The electric current of lithium battery is by relay normally closed switch K1 and the hand switch K2 that loads supplies with, have only when electric main has a power failure and hand switch K2 when closed storage battery E just power to the inversion oscillator, the vibration of the gap of inversion oscillator is to step-up transformer B2 input high-frequency current, high frequency voltage after step-up transformer B2 boosts to lamp tube power supply.
Outstanding contributions of the present utility model are that step-up transformer B2 protective device is set; that is: the filament of fluorescent tube A end is serially connected on the loop of the input current of inversion oscillator; electric current is from the positive pole of battery, and the filament of the K2 that flows through, K1, L2, fluorescent tube A end, the base stage of R3, VT1, emitter, common ground to the negative pole of battery form the loop.Under normal circumstances, during VT1 vibration conducting, battery is step-up transformer B2 input high-frequency current by the collector and emitter of L1 and C1, VT1, and the high-frequency current of the output winding L3 of step-up transformer B2 forms the loop from B end, A end, L2, battery E, common ground, the emitter of VT1, the collector electrode of fluorescent tube.When fluorescent tube was pulled down in maintenance, although hand switch K2 closure, battery E was cut off for the input current that the inversion oscillator provides, and VT1 ends, thereby prevented that effectively step-up transformer B2 is broken down by high-voltage.In common emergency light, owing to there is not described protective device, this phenomenon often occurs: hand switch is not closed during because of the replacing fluorescent tube, the high pressure that the conducting of inversion oscillator produces will cause step-up transformer breakdown.Therefore, the utility model is provided with the protective device of step-up transformer B2, is the notable feature of emergency light.
