Abstract

The utility model discloses an automatic luminescence and catacaustic chip, comprising a catacaustic chip, a photosensitive tube, a light-emitting diode, a DC amplifying circuit and a centrifugal switch outer shell. When the illuminance is smaller than 2-4 ux, and a bicycle runs, the catacaustic chip luminates automatically. When the illuminance is greater than 2-4 ux, or the bicycle stops rotation, the catacaustic chip extinguishes automatically, so that drivers of motor vehicles and pedestrians can pay attention to the bicycles with catacaustic chip. Therefore, traffic accidents can be reduced, and urban night scene is beautified.

Description

Automatic luminous heliopiece

The utility model relates to a kind of cycle wheel light echo sheet.

Present cycle wheel light echo sheet, also being side reflector is passive type, relies on extraneous irradiation luminous (reflective), brightness is very weak, does not have the external light source irradiation not luminous, should not be seen clearly by the people.

The purpose of this utility model is to provide a kind of energy luminous light echo sheet automatically, no matter has or not the ambient light irradiation, and itself enough can be luminous automatically.When ambient light illumination was rotated less than 2-4Lux and cycle wheel, light-emitting diode was luminous automatically in the light echo sheet, and when ambient light illumination stopped operating greater than 2-4Lux or cycle wheel, light-emitting diode extinguished automatically in the light echo sheet.Can cause that thus motor vehicle operator and pedestrian note having the bicycle of automatic luminous light echo sheet, reduce traffic accident, and the beautifying city night scene.

Figure 11 for the utility model by site plan on bicycle.

The utility model is by automatic luminous light echo sheet shell, photosensitive tube, light-emitting diode, and dc amplification circuit, centrifugal switch and battery are formed.Wherein the shell of light echo sheet adopts existing redness or the yellow translucent poly-rare plastics of stupid second to make.Principle of work is: when bicycle stopped, the centrifugal switch interrupting power circuit was not worked, and luminous demonstration is unglazed, not consuming electric power.Bicycle rotates back centrifugal switch closure, and circuit power is connected, if ambient light illumination greater than 2-4Lux, photosensitive tube 3DU conducting, BG ₁, BG ₂End, the display led no current passes through, and is not luminous; When ambient light illumination during less than 2-4Lux, photosensitive tube 3DU ends, BG ₁, BG ₂R is passed through in conducting ₂Current limliting makes LED have the 10-15mA electric current to pass through, and LED sends shows signal.

Circuit connects as Fig. 2,3DU emitter power connection negative pole, and the 3DU collecting electrode meets BG ₁Base stage and R ₁One end, R ₁Another termination K ₂End, BG ₁Collecting electrode meets K ₂End BG ₁Emitter meets BG ₂Base stage, BG ₂Emitter meets R ₂One end, R ₂Other end power connection negative pole, BG ₂Collecting electrode connects the LED negative pole, and the LED positive pole meets K ₂End, K ₁The termination power positive pole.

Automatic luminous light echo sheet external form and structure are circular as Fig. 3, microscler as Fig. 4, prismatic such as Fig. 5, Fig. 6.Circular automatic luminous light echo sheet shell (1) is circular, and the gong silk hole (2) that shell is fixed on the bike spoke is Long Circle.The shell of microscler automatic luminous light echo sheet is that (26) are microscler, and the gong silk hole (2) that is fixed on the rung bar is circle, and the automatic luminous light echo sheet shell of prismatic (27) section is a prismatic, and the gong silk hole that is fixed on the rung bar is circular (2).Three kinds of automatic luminous light echo sheets, its inner structure is centrifugal switch (3), two joint No.5 cells (4), light-emitting diode (5) circuit card (6), photo-transistor (7) photometry partly leans out outside the housing as Fig. 3, Fig. 4, or within housing as Fig. 5, the fastening lower casing gong silk hole (8) of going up.

Centrifugal switch adopts weight hammer type such as Fig. 7, by tup (9), and spring (10), reed (11), housing compositions such as (12).Wherein normality lower spring (10) is enclosed within on the tup (9) and by elastic force tup (9) is resetted, reed (11) disconnects, not conducting of circuit, when illuminance tup (9) during less than 2-4Lux and during bicycle running, under action of centrifugal force, overcome the elastic force of spring (10) and oppress reed (11), make its connection, circuit turn-on, LED work, the light echo sheet is luminous.

The utility model also can adopt following several centrifugal switch:

A, disc spring formula such as Fig. 8, an end of disc spring (13) are fixed in housing (14) midway location, and the other end and tup (16) connect, and under centrifugal action, tup (16) is overhanging, connect circuit turn-on with reed (15).

B, Extension Spring-type such as Fig. 9, an end of extension spring (17) are fixed on housing (19) top, and the other end and tup (18) connect, and under action of centrifugal force, tup (18) overcomes the pulling force of extension spring and overhangingly connects circuit turn-on mutually with reed (20).

C, reed-type such as Figure 10, following reed (21) is fixed on the insulcrete (25) with upper reed plate (24), all use flexible metallic material, there are counter weight (23) and contact (22) in upper reed plate (24) top, upper reed plate (24) and following reed (21) afterbody all with the circuit connection, under the situation of centnifugal force greater than counter weight, upper reed plate (24) overcomes self rigid elastic force and bending, and contact circuit turn-on with following reed (21).

Automatic luminous light echo sheet is fixed on the bicycle spoke at bicycle position such as Figure 11, and this example is microscler automatic luminous light echo sheet.Circular automatic luminous light echo sheet and the automatic luminous light echo sheet of prismatic are also all installed in the bicycle position by its microscler automatic luminous light echo sheet.
