Abstract

The utility model relates to a turning light for a bicycle, mainly comprising an electric source, electronic switches, a time delay circuit, a logic circuit, a drive LED circuit and a pulse generator. The electronic switches and the time delay circuit comprise two circuits which are a left turning circuit and a right turning circuit. When one of the electronic switches is pressed, the time delay circuit generates a signal to the logic circuit, the logic circuit gives two signals to control the drive LED circuit and enable one of LED bright lastingly and the other LED flashing, and left turning and right turning can be known via comparison. Then the electronic switches are presses simultaneously, the two sets of LEDs radiate lastingly to be used as a mark for driving at night. The utility model can improve the security of driving at night for bicycles.

Description

Turning light of bicycle

The utility model relates to a kind of car light, especially a kind of turning of bicycle lamp.

Domestic most of cities street lighting at night is poor at present, and bicycle quantity is many, turns to night to see clearly, often has traffic accident.

The purpose of this utility model provides a kind of turning of bicycle lamp, and it can improve bicycle in night travel safety, shows clear and definite turn sign when especially turning to, alerting.

The purpose of this utility model is achieved in that the turning of bicycle lamp mainly partly is made up of power supply, electronic switch and time delay circuit, decision circuit, driving LED circuit and impulse deviser five.Electronic switch and time delay circuit comprise left-hand rotation, the two cover circuit of turning right, and when pressing one of them, circuit produces signal to decision circuit, a decision circuit and provides two paths of signals, control Driver Circuit, for two paths of LED, one group of flash of light, one group of Chang Liang, contrast is promptly changeed as can be known to the left or to the right.When left and right when turning to button to press simultaneously, decision circuit output two-way same signal, control Driver Circuit makes two groups of LED Chang Liang, can make the sign of going out walking in the night.More than two methods, (default 1-5 minute) time delay circuit SELF CL entire circuit after work a period of time, lamp goes out, circuit is in keeps marquis's state, in case people's malfunction button is arranged, guarantees to save power supply, when pressing stop key, then all circuit all quit work, and lamp does not work, and circuit recovers to keep marquis's state.

Owing to adopt technique scheme, when control circuit is in when keeping marquis's state, consumed power is few, power saving and decide light and represent steering direction with the flash of light contrast, ocular and clear, and night visual range is greater than 20 meters; Owing to adopt timing circuit can prevent the malfunction switch, the long-time bright lamp that causes; Body seal prevents that rainwater from entering in addition, uses components and parts few, easy to install.The utility model has improved bicycle night travel safety, reduces accident rate.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the utility model constructional drawing.

Fig. 2 is the utility model scheme of installation.

Fig. 3 is the utility model schematic circuit diagram.

Among the figure 1, base plate 2, shell 3, battery 4, circuit card 5, connecting strap 6, electronic switch 7, bicycle 8, headlight 9, back light

Shell in Fig. 1 (2) is tightly connected with drain pan (1), circuit card (4) by screw retention on drain pan (1), electronic switch (6) is positioned on the shell (2), battery (3) is contained in the shell, whole housing (1,2) is installed in respectively on the handlebar or on the rear object carrier with screw and clip by connecting strap (5), headlight (8) is contained in the seal box together with power supply (3), control circuit (4) and switch (6), sees Fig. 2.K1 is the left-hand rotation switch in Fig. 3, and K2 is the right-hand rotation switch, and K3 is for stopping.When pressing K1, the forward and backward left-handed turning that shows simultaneously, promptly forward and backward left blinking red lamp, forward and backward right red light is decided light, and vice versa.When pressing K1K2 simultaneously then before and after two red lights all decide light " can be used as the night flight or navigation lamp.The utility model is provided with timing function, can set 1-5 minute duration of light, extinguishes automatically after then.

Claims
