Description
The utility model is a kind ofly to be used for occasion such as speedway prompting driver's vigilance or as the automatic warning light of Bicycle Tail Light, to belong to the automatic alarming device technical field.
The warn device that uses on the speedway adopts reflectorized paint usually at present, can reflected signal when automobile headlamp shines, belong to passive reflecting type scheme, because the range of automobile headlamp has certain limitation and light to have stronger directionality, when the speed of a motor vehicle is very high, the driver sees that the reaction time behind the signal is very short, can't make the driver that the situation at the road place of warning is accomplished prior intelligent preparation, is unfavorable for traffic safety.Existing Bicycle Tail Light also is passive reflecting type structure, is unfavorable for the traffic safety in night.
The purpose of this utility model is at the deficiencies in the prior art, a kind of automatic alarming device in night of energy active illuminating is provided, neither use AC power, can work the long period again, be mainly used in the occasion that needs such as turning, the branch road prompting driver of speedway watches out for, also can be used as Bicycle Tail Light, use this automatic alarming device to help traffic safety.
The utility model adopts the optical semiconductor power technology, make warn device luminous automatically in night, and extinguishes daytime automatically.The utility model is made up of power supply, light-emitting device and shell, is characterized in that light-emitting device can be made of automatic switch, electro coupled oscillator and light emitting semiconductor device, and automatic switch adopts light-operated switch, light-emitting device to seal in the shell of light-permeable at one end.When ambient brightness was attenuated to a certain degree, light-operated switch was opened, and made electro coupled oscillator produce vibration, and the light emitting semiconductor device flicker is luminous; When ambient brightness was strengthened to a certain degree, light-operated switch cut out, and light emitting semiconductor device stops luminous.The ambient brightness that light-operated switch opens or cuts out can determine as required.
The utility model compared with prior art has the advantages such as effective, easy to use, with low cost and easy popularization of warning.Owing to adopt hermetically-sealed construction, can be exposed to the elements in outdoor long-term use.Adopt light emitting semiconductor device as luminous body, not only power saving, and long service life.Luminous intensity, color and scintillation frequency can determine according to actual needs, spot light can also be formed needed literal, symbol or pattern, so that improve the effect of warning.The utility model adopts the active illuminating scheme of warning, and helps traffic safety.
Fig. 1 is circuit theory diagrams of the present utility model; Fig. 2 is used for the example approach structural representation that highway is warned; Fig. 3 is the embodiment structural representation as Bicycle Tail Light.
