Abstract

The invention provides an anti-dazzling intelligent dimming triangular warning board and aims to overcome two major defects that conventional LED flashy triangular warning boards are fixed and unitary in brightness and are not eye-catching under sunlight irradiation in sunny days and too dazzling in dark nights. The anti-dazzling intelligent dimming triangular warning board is composed of a battery (1), a control switch (2), a battery voltage boosting module (3), a flashing brightness control module (4), a photosensitive diode (5) and triangularly-arranged LED flashing light emitting tubes (6) which are electrically connected in order. The anti-dazzling intelligent dimming triangular warning board is characterized in that the flashing brightness control module (4) and the photosensitive diode (5) are newly added inside the warning board. The flashing brightness control module and the photosensitive diode are applied on the LED flashing triangular warning board at the same time, so that voltage going to LEDs (light emitting diode) can be increased or decreased automatically according to various actual brightness needs in sunny days, cloudy days and overcast days and at dusk and night so as to realize automatic dimming.

Description

Technical field

[0001] The present invention relates to a triangular warning sign for automobile failure, which is a highly eye-catching triangular warning sign with LED flash placed on the road behind the car whenever a car breaks down (breaks down) or an accident occurs on the road, which belongs to the spare parts of the car. Vehicle failure triangle warning sign field. Background technique

[0002] At present, there is a great safety hazard in the LED flashing triangle warning signs purchased in the auto parts market and online: that is, there is only a single fixed flashing brightness, and it cannot be automatically adjusted according to the large difference between day and night, sun and night on the road. . If the brightness of this traditional LED triangular warning sign is fixed at a high brightness suitable for flashing under sunlight, once it is used at night, it will cause glare and dazzle to every car behind, which will cause a great safety hazard . Therefore...
