Abstract
The utility model discloses an LED control circuit of a triangle warning board comprising an LED disposed on the triangle warning board. A control circuit of the LED is constituted by a first chip (U1) and a second chip (U2). A power supply anode is connected with a power supply cathode sequentially by a first chip (U1), a second chip (U2), and an LED. The first chip (U1) and the second chip (U2) can be used to control the flickering of the LED. The LED control circuit is advantageous in that the working state of the LED can be changed into flickering, the dynamic effect can be provided, and the attention of the driver can be attracted, and therefore the warning effect of the triangle warning board can be obviously enhanced, the secondary accident can be prevented; the structure is simple, and the implement is convenient.
Description
Technical field
The utility model relates to circuit field, is specifically related to a kind of LED control circuit of triangle warning plate.
Background technology
Warning sign is the conventional jury rig on automobile, the general state triangular in shape of outward appearance, so be called again triangle warning plate, must be in strict accordance with " law on road traffic safety " requirement, the passive refractive body of being made by the plastics reflectorized material, principle is that the car owner on the way runs into while happening suddenly traffic accident, utilizes the reflective function of warning sign, remind other vehicle to note dodging, to avoid second accident.The LED that Chang Liang has been installed on the triangle warning plate had at present further improves alarming effect, but the driver can produce visual fatigue when driving for a long time, and static triangle warning plate can not guarantee that the driver can make the reply reaction in time, and alarming effect is bad.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of LED control circuit of triangle warning plate, can solve the LED Chang Liang of existing triangle warning plate, the bad problem of alarming effect when the driver produces visual fatigue.
The utility model is achieved through the following technical solutions:
A kind of LED control circuit of triangle warning plate, comprise the LED on triangle warning plate, the control circuit of described LED mainly is comprised of the first chip U1 and the second chip U2, positive source connects power cathode through the first chip U1, the second chip U2, LED successively, and described the first chip U1 and the second chip U2 control the LED flicker.
The further improvement of the utility model scheme is that the model of described the first chip U1 is NE555.
The further improvement of the utility model scheme is that the model of described the second chip U2 is MH7702.
The further improvement of the utility model scheme is that the cycle of described LED flicker is 0.3 ~ 1 second.
The further improvement of the utility model scheme is, described LED comprises the branch road of three parallel connections, and every route a plurality of LED lamp pearl and a resistance are composed in series; Can guarantee that other branch roads are unaffected in the situation that there is LED lamp pearl to damage.
The further improvement of the utility model scheme is that described every branch road correspondence is arranged on three limits of triangle warning plate.
The utility model advantage compared with prior art is:
One, the operating state of LED is changed into to flicker, form dynamic effect, attract driver's attentiveness, obviously strengthened the alarming effect of triangle warning plate, avoid the generation of second accident;
Two, simple in structure, it is convenient to implement.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the LED structural representation.
Embodiment
A kind of LED control circuit of triangle warning plate, comprise the LED on triangle warning plate, described LED comprises the branch road of three parallel connections, and every route a plurality of LED lamp pearl and a resistance are composed in series, and described every branch road correspondence is arranged on three limits of triangle warning plate; The control circuit of described LED mainly is comprised of NE555 the first chip U1 and MH7702 the second chip U2, positive source connects power cathode through NE555 the first chip U1, MH7702 the second chip U2, LED successively, and described NE555 the first chip U1 and MH7702 the second chip U2 control LED and glimmer with the cycle of 0.3 ~ 1 second.
