Abstract
The utility model provides an indicating lamp for passenger less taxies. The utility model comprises an outer shell and an indicating lamp circuit, wherein the indicating lamp circuit comprises a photosensitive resistance. The photosensitive resistance can change self resistance values according to sensed light intensity, and changes the lighting brightness of the indicating lamp circuit as a result. Due to the adoption of the technical scheme of the utility model, passengers can clearly distinguish taxi states beyond thirty to fifty meters. Simultaneously, the utility model does not interfere with vehicles or pedestrians at the opposite side.
Description
Technical field
The utility model relates to automobile-used indicator lamp, relates in particular to the empty wagons indicator lamp that a kind of taxicar is used.
Background technology
At present, the empty wagons indicator lamp is convertible structure mostly in the general-duty taxicar, embodies vehicle-mounted state by whether luminous the font on it (normally " empty wagons " printed words) is.But the volume of convertible structure is less relatively, and simultaneously there is light intensity heavy handled problem again in luminous font, if light too a little less than, under the interference of extraneous high light, be not easy to distinguish vehicle-mounted state; Often make the person of picking up be difficult to distinguish.If otherwise light is too strong, then night or rainy weather are easy to generate and dazzle the eyes, and make the opposite vehicles or pedestrians have potential safety hazard.
So just needs are a kind of can be according to the taxicar empty wagons indicator lamp of its display brightness of environment light intensity automatically regulating.
Summary of the invention
The purpose of this utility model provides a kind of light of responding to external environment, the taxicar empty wagons indicator lamp of automatic compensation luminous intensity.
The technical scheme that the utility model adopted is: hot pouring plastic stent on printing opacity PC film, the light-emitting diode (LED) by photoconductive cell control in parallel on the wiring board of indicator lamp.When extraneous light changed, according to the intensity difference, photoconductive cell can change its resistance, thereby the operating voltage of regulating diode changes LED lightness, to reach the purpose of automatically regulating luminous intensity.
According to the utility model: a kind of taxicar empty wagons indicator lamp is provided, comprise shell and indicator light circuit, described indicator light circuit comprises photoconductive cell, and described photoconductive cell changes the resistance of himself according to its light intensity of experiencing, thereby changes the luminosity of described indicator light circuit.
According to a preferred embodiment of the present utility model, described indicator light circuit comprises photoconductive cell, op amp, aerotron, light-emitting diode and current-limiting resistance; Described current-limiting resistance is serially connected on the described light-emitting diode; Described light-emitting diode has a plurality of, constitutes a pattern jointly.
The described shell of indicator lamp of the present utility model comprises following structure: an after poppet, have several hot pick posts on it, and the wiring board of described indicator light circuit is fixed on the described after poppet by described hot pick post, also has several mounting holes on the described after poppet; One front frame has several card bases on it, described card base passes the mounting hole of described after poppet and is fixed on the described after poppet, thereby realizes the connection of front and back support; After described front and back support was connected, described indicator light wire board was between described front and back support; The PC film of one printing opacity is positioned at the front of described front frame, sees through the pattern that light-emitting diode constituted on the visible described indicator light circuit wiring board of described PC film.
In order to obtain preferable result of use, described PC film surface is through twice printing and with UV curing.
Used the taxicar indicator lamp of the technical solution of the utility model, can make the person of picking up distinguish vehicle-mounted state so that external enwergy is clear, the opposite vehicles or pedestrians have not been caused interference again simultaneously at 30-50 rice.
Description of drawings
Feature of the present utility model, essence and advantage will be below become more obvious after the further describing in conjunction with the accompanying drawings and embodiments:
Fig. 1 is the insight structural map of indicating lamp structure of the present utility model;
