Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0011] Such as figure 1 Shown, the present invention is made up of following four parts:

[0012] A certain timing control circuit, the core device is a 555 timer, which is used to drive and control the strobe rate of the ultra-bright light-emitting diode LED in the display circuit, and is the core part of the present invention.

[0013] A photoresistor control circuit, the photoresistor controls the stroboscopic speed of starting and closing the controller and display circuit.

[0014] A display circuit, which receives the output signal of the timing control circuit, adopts a super bright yellow LED display circuit, which is composed of super bright light-emitting diodes connected in series and parallel.

[0015] A rectification circuit is used to provide DC voltage for the timing control circuit (timer).

[0016] Circuit principle such as...

Abstract

The invention relates to a traffic warning fog-proof lamp used in toll islands or both sides of fog sections along freeways to provide sight induction for drivers in foggy or abnormal weather. The invention comprises a time control circuit as a core component, a rectifier circuit which provides a direct current power supply for the time control circuit, a display circuit which receives output signals of the time control circuit and a photosensitive resistance control circuit; wherein, the output of the photosensitive resistance control circuit is connected with the time control circuit to control the opening and closing of a timer and the stroboscopic speed of the display circuit; the photosensitive resistance control circuit comprises a multi-vibrator and a stroboscopic control circuit; the display circuit consists of ultra bright blue light emitting diodes connected in a parallel and serial way; a 555 timer is adopted as the time control circuit. The invention is used for automatically turning off or turning on the traffic warning fog-proof lamp and providing sight induction for drivers according to visibility degree. The lamp has a simple structure, is practical and plays a good role of energy saving.

Description

technical field [0001] The invention relates to a traffic warning anti-fog lamp, which is used on the head of a toll island or on both sides of a foggy section along an expressway, and is automatically activated in foggy days or when the weather is abnormal and guides the driver's line of sight. Background technique [0002] In the field of traffic, regardless of the toll station toll island or the fog section of the highway, traffic warning and anti-fog lights are essential. The current anti-fog lights are powered by mains or solar energy around the clock. However, under the condition of fine weather and high visibility, the anti-fog lights still work normally, which not only has no effect, but also increases the waste of energy. Therefore, need a kind of according to the strength of visibility, the traffic warning anti-fog lamp that can shut down automatically, start, solve the present situation of current energy waste. Contents of the invention [0003] In order to ove...
