Describe concrete structure of the present utility model in detail below in conjunction with embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include luminophor (1) and control device (2), wherein luminophor (1) is an electric crystal, include light tiles (1) and light-emitting section (11), control device (2) includes oscillatory circuit and booster circuit, wherein oscillatory circuit includes resistance R 1, R2, R3, capacitor C 1, C2 and triode T, booster circuit includes step-up transformer Tr, one end of resistance R 3 respectively with resistance R 1, the end of R2 connects, the other end of R3 is connected with the base stage b of triode T, resistance R 1, the other end of R2 is connected with power supply respectively and is connected with an end of capacitor C 1, the other end of capacitor C 1 is connected with the Tr2 end of step-up transformer Tr, capacitor C 2 is connected between the base stage b and collector c of triode T, the emitter e of triode T is connected the Tr3 of step-up transformer Tr with the Tr1 end of step-up transformer Tr, the Tr4 end is connected with the two ends of luminophor (1) respectively, as shown in Figure 2.For the ease of installing and control, above-mentioned control device (2) is installed on the box body (4), and loam cake (5), battery cover (6) also can be housed on the box body (4), and is connected with switch (3) on the control device (2), switch (3) can be packed on the box body (4), as shown in Figure 1.
Figure 3 shows that the utility model is used for the structural representation of school bag; the box body (4) that is equiped with control device (2) can be placed the inboard of school bag; light tiles (1) and light-emitting section (11) are placed the outside of school bag; and can cover the material of layer of transparent thereon; in order to protection light tiles (1) and light-emitting section (11); wherein the fluorescent powder of light tiles (1) and the available different colours of light-emitting section (11) is made; make light tiles (1) burst send the fluorescence of different colours, make light-emitting section (11) segmentation send the fluorescence of different colours.
The utility model in use, toggle switch (3), energized, then resistance R 1, R2, R3 provide quiescent bias current for triode T, make triode T conducting, at this moment step-up transformer Tr and capacitor C 2, resistance R 2 constitute positive feedback loop, make circuit produce resonance, resonance potential becomes a high pressure behind step-up transformer Tr, offer light tiles (1) and light-emitting section (11); Above-mentioned switch (3) can be range switch, and when its group during in state 1, light tiles (1) flicker is dialled when state 2, and circuit disconnects, and dials when state 3, and light tiles (1) and light-emitting section (11) all glimmers, and group when state 4, light-emitting section (11) glimmers.
The utility model is owing to be provided with power supply, therefore, do not need the strong illumination can be luminous; In addition, the utility model so visibility is far away, can play safe preferably reminding effect owing to adopt the fluorescent material of good luminous performance, reduces the generation of traffic hazard; In addition, the utility model also can be used for going sightseeing, so that seek the companion.The utility model is a novel light-emitting device a kind of rational in infrastructure, simple, safe and practical.
