The particularly proud car owner of automobile will adopt light as luminescent device at present, the variation of face vehicle motoring condition after accusing, adopt light to make luminescent device, its shortcoming is that the life-span is limited, the break-make of especially big electric current and running environment abominable, the easier filament breaking that makes, and the mono-light prompt caused traffic accident because of light loses efficacy easily.Chinese patent CN2192506 and CN2150102 disclose respectively a kind of " multi-purpose vehicle(MPV) secure screen display " and " a kind of motoring condition electronic graph-text telltale ", they have adopted light emitting diode to show, has suggesting effect preferably, but they have all used complicated light emitting diode matrix, the circuit complexity, and adopt common river diode, brightness is low, the cost height.
The utility model is at the above-mentioned deficiency of prior art, provides that a kind of display brightness height, circuit are simple, long service life and the motoring condition read out instrument that can arbitrarily settle, cooperate the existing display lamp of automobile to use.
The purpose of this utility model is achieved in that
This motoring condition read out instrument is sat the end of by and is connected movable support, is fixed with substrate on the support, and display circuit is fixed on the substrate, light shield and substrate engagement.To selecting circuit, form by NE555 monostable circuit and R, C silicon control delay control circuit by single, double for the display circuit of this device.The positive pole of original left and right steering indicating light of automobile and brake lamp respectively with single, double to selecting circuit to be connected, input voltage, three import line connect respectively unidirectional conducting diode form single, double to conducting, by two output points output voltage individually or simultaneously.2 output voltage is respectively through one 7812 output voltages individually or simultaneously.2 output voltage is respectively behind one 7812 three-terminal voltage-stabilizing integrated package, connect the NE555 monostable circuit again, 3 pin output lines of the monostable volt circuit of NE555 connect a resistance, be connected to transistor control circuit, form switching with R, C SCR control circuit again and be connected, drive the dynamic light-emitting of super brightness light emitting diode group.R, C SCR control circuit are formed in parallel by at least two SCR control unit, at least two above superhigh brightness LEDs of serial or parallel connection in each unit, and each silicon control trigger end is connected in last control unit, and its delay time is determined by R, C.
This device can be installed on the automobile with spiral shell by base, also the end can be sat and make with magnet, is installed on the automobile with the magnetic force form.
The luminous intensity of the superelevation highly luminescent diode that the utility model is used is greater than 600mcd, and the total electricity of the superhigh brightness LED of each SCR control unit is less than the maximum current flow of this control unit silicon control permission.
The utility model has adopted time base circuit 555 to be oscillating circuit, serves as the time-delay controlling unit with R, C and silicon control, and circuit is simple, and the state that can be the braking of turning left to turn right in the running car changes the light prompt that dynamic change is provided, and has better visual effect.Adopt the super brightness light emitting diode, luminous intensity is used under the voltage conditions of regulation greater than 600mcd, and its life-span surpasses conventional luminescent device.This device can be installed in the optional position of automobile.
Below in conjunction with accompanying drawing, enforcement of the present utility model is described further:
