Abstract
A multifunctional luminous electric torch comprises an elliptical casing and three high-brightness LEDs. The elliptical casing consists of an upper cover casing and a lower cover casing which are connected to be suitable for handholding in a fastening manner, the three high-brightness LEDs are fixed in the front of the casing, a key switch is arranged in the front of the upper cover casing, a storage battery is mounted inside the rear of the casing, a square groove is arranged on the outer surface, corresponding to the key switch, of the lower cover casing, a rotation plug is hinged into the groove, a control circuit board is arranged between a plug in the casing and the key switch, the control circuit board outputs weak current in a charging manner to drive the LEDs to emit weak light for illumination, and the control circuit board is respectively and electrically connected with the LEDs, the key switch and the storage battery. The pressed key switch is pressed to turn on the storage battery power supply to light the LEDs so as to realize the basic emergency illumination function of the electric torch, the rotation plug is rotated out of the groove to be plugged into a household power socket when charging at night, and the control circuit board performs charging protection on the battery, and simultaneously a voltage dividing and current limiting circuit in the circuit board outputs low current to drive the LEDs to perform weak light illumination, so that the multifunctional luminous electric torch can be simultaneously used as a luminous lamp for illumination when being charged.
Description
Technical field
The utility model relates to the high-brightness LED lamp flashlight, particularly a kind of multi-functional noctilucence flashlight with night-light illumination.
Background technology
The high-brightness LED lamp flashlight has become the commodity of household indispensability, owing to adopt LED to substitute traditional tungsten than miniature bulb, makes present LED flashlight adopt the flashlight energy consumption of miniature bulb lower than tradition, and brightness is higher.But the subject matter that present rechargeable LED lamp flashlight exists has: just use when 1. having only the emergency lighting of needs, the usual all long-time idle built-in battery overdischarge of flashlight then and damaging reduces the service life of LED lamp flashlight greatly; 2. LED lamp flashlight does not have the function of automatic degree of regulation, so it can not need old man, the very inconvenience of child of luminescent lighting as luminous lamp low light level illumination use for the room.
The utility model content
For addressing the above problem, the utility model is intended to propose a kind of multi-functional noctilucence flashlight, can be directly and the household outlet illumination of pegging graft as the luminous lamp low light level use.
The technical scheme in the invention for solving the above technical problem is: multi-functional noctilucence flashlight, contain by the be fastened and connected oval-shaped shell that becomes to be fit to hold and be fixed on three LEDs of housing front portion of shell of top cover and lower cover shell, the shell of top cover front portion is provided with key switch, in the housing rear portion, battery is installed, the lower cover shell outer surface of corresponding key switch is provided with the square groove, hinged rotary connector in the groove, it is characterized in that: being provided with charging output weak current driving LED between plug in housing and the key switch and sending the control circuit board of low light level illumination, control circuit board respectively with LED, key switch connects and battery is electrically connected.
In the control circuit board of the present utility model, charging circuit is connected with three LEDs of switch triode with parallel connection through key switch, series connection one dividing potential drop current-limiting circuit between the LED lamp string of charging circuit and parallel connection, and the base stage of switch triode is connected with the dividing potential drop current-limiting circuit.
The beneficial effects of the utility model are: press of key switch conducting battery feed is lighted LED, realizes the basic function of emergency illumination of flashlight; Night is when charging; from groove, screw out rotary connector and insert household outlet; control circuit board carries out the protectiveness charging to battery; carry out low light level illumination through the dividing potential drop current-limiting circuit output LOW current driving LED in the circuit board simultaneously, make the utility model in charging, serve as the luminous lamp illumination and use.

Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is an electrical block diagram of the present utility model;
Among the figure: 1. housing; 2. shell of top cover; 3. lower cover shell; 4.LED; 5. key switch; 6. battery; 7. groove; 8. rotary connector; 9. control circuit board; 10. charging circuit; 11. switch triode; 12. dividing potential drop current-limiting circuit.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1～multi-functional noctilucence flashlight shown in Figure 3, contain by the be fastened and connected oval-shaped shell that becomes to be fit to hold 1 and be fixed on three LEDs 4 of housing 1 front portion of shell of top cover 2 and lower cover shell 3, shell of top cover 2 front portions are provided with key switch 5, in housing 1 rear portion, battery 6 is installed, lower cover shell 3 outer surfaces of corresponding key switch 5 are provided with square groove 7, hinged rotary connector 8 in the groove 7, be connected a charging output weak current driving LED 4 between plug in housing 1 and the key switch 5 and send the control circuit board 9 of low light level illumination, control circuit board 9 respectively with LED4, key switch 5 connects and battery 6 is electrically connected, specifically be that charging circuit 10 in the control circuit board 9 is connected with three LEDs 4 in parallel through key switch 5 and switch triode 11, series connection one dividing potential drop current-limiting circuit 12 between the LED4 lamp string of charging circuit 10 and parallel connection, the base stage of switch triode 11 is connected with dividing potential drop current-limiting circuit 12.
Describe concrete operation principle of the present utility model and action below in detail.
As Fig. 1～Fig. 3 and shown in Figure 4, night is when charging to the utility model, shown in rotate rotary connector 8 out concavo-convex and insert household electrical appliances 220V supply socket, bridge rectifier, filtering and the voltage stabilizing of the charging circuit 10 in control circuit board 9 are charged to battery 6, and this moment, key switch 5 was in off-state; Send low light level illumination through treated VD through the step-down generation weak current driving LED4 lamp string in parallel of dividing potential drop cut-off current simultaneously, i.e. during the utility model charging, the insertion household outlet can be filled the use of light luminous lamp.When the utility model charging finishes, extract rotary connector 8 and screw in the groove 7 it hiding from the household electrical appliances supply socket, battery 6 directly makes control circuit board 9 charged, push closed key switch 5, the medium voltage of dividing potential drop current-limiting circuit 12 makes the emitter-base bandgap grading and the colelctor electrode conducting of switch triode 11, the LED4 lamp string of big current drives parallel connection is luminous, realizes the basic function of traditional LED4 flashlight.
