Abstract
A flashing schoolbag capable of adjusting brightness automatically consists of a schoolbag body, a flashing circuit, a battery, a light sensitive circuit and a single chip microcomputer circuit. The schoolbag body is provided with the battery, the flashing circuit is arranged on a surface, facing to others, of the schoolbag body and is connected with the battery and the single chip microcomputer circuit, the single chip microcomputer circuit controls the flashing circuit, the light sensitive circuit is connected with the battery and the single chip microcomputer circuit, the flashing circuit consists of an LED, the single chip microcomputer circuit can measure brightness of an external environment via the light sensitive circuit so as to control the brightness of the flashing circuit, as a brightness adjusting function is added, the brightness of the LED can be correspondingly reduced at night or in a weak-light environment, the energy-saving purpose is achieved while safety warning effect is realized, when in day time or in a brighter environment, the brightness of the LED can be strengthened automatically so as to increase comparison and difference between the schoolbag body and the surrounding environment, and accordingly personal safety of students is improved more reliably.
Description
Technical field
The utility model patent relates to a kind of flash of light school bag, particularly can regulate the flash of light school bag of brightness automatically.
Background technology
At present students in middle and primary schools' traffic safety problem is one of problem of being concerned about the most of parents of student and school teacher always, also can be described as a social concerns problem.The safety that students in middle and primary schools' traffic safety is particularly gone to school on the road that classes are in the winter time is difficult to guarantee, the colour of sky is black and mist is usually arranged on the road that classes are over of going to school winter, and automobile driver can not in time be found the student in the place ahead sometimes, and causes the generation of traffic accident.The product that some case and bag flashers are arranged in the market can play certain warning function, but its flash of light part brightness is constant, and the battery power consumption is many.
The utility model content
The purpose of the utility model patent aims to provide a kind of simple and reasonable, easy to use; Can play the effect of caution, safety; And energy-conserving and environment-protective can be regulated the flash of light school bag of brightness automatically, to overcome brightness constancy in the prior art, the many weak points of power consumption.
The technical scheme that the utility model patent is adopted is: a kind of flash of light school bag that can regulate brightness automatically; Be made up of school bag, flasher circuit, battery, photosensitive circuit, single chip circuit, be provided with a battery in the described school bag, the one side towards other people of school bag is provided with a flasher circuit; Flasher circuit is connected with battery; And be connected with single chip circuit, single chip circuit control flasher circuit, photosensitive circuit connect battery and link to each other with single chip circuit; Described flasher circuit is made up of the LED light emitting diode, the LED light emitting diode by the central point of wiring board to around radial pattern arrange.
The utility model has the advantages that volume is little, in light weight, safe ready, flasher circuit can active illuminating, brightness is big, can be good at pointing out the automobile driver at student rear in time to find the student, guarantee student's personal safety.Because increased the function of regulating brightness, this product can reduce the brightness of emitting components accordingly at night or the darker environment of light application ratio, in security warning, plays purpose of energy saving; And by day or ambient brightness stronger the time, the brightness of emitting components is with automatic grow, to improve the contrast and the difference of school bag and surrounding environment.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: 1, school bag, 2, flasher circuit, 3, battery, 4, photosensitive circuit, 5, single chip circuit, 6, the LED light emitting diode.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in the figure, a kind of flash of light school bag that can regulate brightness automatically is made up of school bag 1, flasher circuit 2, battery 3, photosensitive circuit 4, single chip circuit 5; It is characterized in that described school bag 1 is provided with a battery 3; The one side towards other people of school bag 1 is provided with a flasher circuit 2, and flasher circuit 2 is connected with battery 3, and links to each other with single chip circuit 5; Single chip circuit 5 control flasher circuits 2, photosensitive circuit 4 connects battery 3 and links to each other with single chip circuit 5; Described flasher circuit 2 is made up of LED light emitting diode 6, LED light emitting diode 6 by the central point of wiring board to around radial pattern arrange.
During the utility model patent work, battery 3 is the entire circuit power supply, and single chip circuit 5 can be measured the brightness of external environment through photosensitive circuit 4, and regulates the brightness of LED light emitting diode 6 in the flasher circuit 2 according to the illumination brightness in the external world; Single chip circuit 5 through the calculating of program, draws the optimal brightness of LED light emitting diode 6 in the flasher circuit 2 after the brightness that records external environment, and controls the brightness of LED light emitting diode 6 according to optimal brightness.The concrete variation is if the brightness of external environment is strong, and the brightness of LED light emitting diode 6 will be strong more; If the brightness of external environment is low, the brightness of LED light emitting diode 6 will step-down.The flash of light of the utility model patented product partly can be regulated brightness along with the power of extraneous light automatically; Can play energy-conservation, prolong the battery effect of service time; Can improve the contrast and the difference of school bag and surrounding environment, improve student's personal safety more reliably.
