Description

a lighting device

The invention is a safety reminding device, which can be installed in various occasions where people need to be reminded, especially in schoolbags.

The existing safety reminder device is just a reflective fluorescent device, which uses the reflection of strong light to emit light in the dark to remind people's attention. If it is installed in a school bag, it reminds people that there are people in front. This reflective fluorescent device exists. The disadvantage is that there must be strong light irradiation in the dark, and its visibility is low, and it needs to be seen at a relatively short distance, which does not meet the safety requirements.

The object of the present invention is to overcome the above disadvantages and provide a light-emitting device that does not require strong light irradiation and has relatively long-distance visibility. The basic structure is reasonable, simple, safe and practical.

The structural representation of the present invention is as shown in accompanying drawing, comprises luminous body (1) and control device (2), and wherein luminous body (1) is transistor, and the input end of control device (2) is connected with power supply, and output end is connected with power supply. The illuminant (1) is connected.

The above-mentioned luminous body (1) can be a luminous sheet (1), can also be a luminous strip (11), or includes a luminous sheet (1) and a luminous strip (11).

The control device (2) includes an oscillating circuit and a boosting circuit, the input end of the oscillating circuit is connected to the power supply, the output end is connected to the input end of the boosting circuit, and the output end of the boosting circuit is connected to the luminous body (1).

The concrete structure of the present invention will be described in detail below in conjunction with embodiment:

Fig. 1 is the structural representation of the embodiment of the present invention;

Fig. 2 is the control circuit diagram of the embodiment of the present invention;

Fig. 3 is a schematic diagram of the structure of the present invention used in a school bag.

Example;

The structure schematic diagram of the present invention is shown in Figure 1, comprises luminous body (1) and control device (2), and wherein luminous body (1) is transistor, comprises luminous sheet (1) and luminous bar (11), controls The device (2) includes an oscillating circuit and a boosting circuit, wherein the oscillating circuit includes resistors R1, R2, R3, capacitors C1, C2 and a triode T, and the boosting circuit includes a step-up transformer Tr, and one end of the resistor R3 is respectively connected to the resistor One end of R1 and R2 is connected, the other end of R3 is connected to the base b of the transistor T, the other end of the resistors R1 and R2 are respectively connected to the power supply and one end of the capacitor C1, and the other end of the capacitor C1 is connected to the step-up transformer Tr The Tr2 terminal is connected, the capacitor C2 is connected between the base b and the collector c of the triode T, the emitter e of the triode T is connected to the Tr1 terminal of the step-up transformer Tr, and the Tr3 and Tr4 terminals of the step-up transformer Tr are respectively connected to the luminous body The two ends of (1) are connected, as shown in Figure 2. In order to facilitate installation and control, the above-mentioned control device (2) is installed on the box body (4), and the upper cover (5) and the battery cover (6) can also be installed on the box body (4), and the control device (2) A switch (3) is connected to the top, and the switch (3) can be fixedly mounted on the box body (4), as shown in Figure 1.

Fig. 3 shows the structure schematic diagram of the present invention for the schoolbag, the box body (4) equipped with the control device (2) can be placed on the inner side of the schoolbag, and the light-emitting sheet (1) and the light-emitting strip (11) can be placed on the inside of the schoolbag. The outside of the schoolbag can be covered with a layer of transparent material to protect the luminous sheet (1) and the luminous strip (11), wherein the luminous sheet (1) and the luminous strip (11) can be made of fluorescent powder of different colors As a result, the light-emitting sheet (1) is made to emit fluorescence of different colors in slices, and the light-emitting strip (11) is segmented to emit fluorescence of different colors.

When the present invention is in use, toggle the switch (3) and turn on the power supply, then the resistors R1, R2, and R3 provide the static bias current for the triode T, so that the triode T is turned on. At this time, the step-up transformer Tr and the capacitor C2, resistor R2 forms a positive feedback loop to make the circuit resonate, and the resonant voltage becomes a high voltage after the step-up transformer Tr, which is provided to the light-emitting sheet (1) and the light-emitting strip (11); the above-mentioned switch (3) can be a band selection switch, when When it is in the dry state 1, the light-emitting sheet (1) flickers; in the dry state 2, the circuit is disconnected; The light bar (11) flashes.

Since the present invention is equipped with a power supply, it can emit light without strong light irradiation; in addition, the present invention has high visibility due to the use of fluorescent materials with good luminous performance; it can play a better role in safety reminders and reduce the risk of traffic accidents. take place; in addition, the present invention can also be used for traveling abroad, so that find companion. The invention is a novel light-emitting device with reasonable structure, simple structure, safety and practicality.
