Abstract
The utility model relates to a character display and flicker warning lamp for police vehicles, which is provided with a transparent lamp cover body, wherein, lighting diode matrix boards are respectively arranged in the lamp cover body, and the lighting diode matrix boards respectively face to a front cover face and a rear cover face, can be connected with each other into arbitrary character groups or figure groups and are arranged in a dot matrix mode; the lighting diode matrix boards are connected with a control box of a flickering and normal-luminous control circuit. Except that the lamp cover needs to use a full-transparent lamp cover, other parts of the appearance of the utility model are basically consistent with the traditional warning lamp arranged on the top of the existing police vehicle, but because a light source of the utility model uses high-brightness lighting diodes and an electronic control circuit, flickering intensity is greatly increased, and a warning system can be effectively operated under abominable meteorological conditions, such as rain, fog, etc.; moreover, the intention of an operating state is definitely displayed by various character groups and various figure groups, which are composed of the high-brightness lighting diodes. The utility model has the advantages of firm structure, convenient operation and use, little power consumption and long service life.
Description
Technical field
The utility model relates to the warning lamp of special vehicle.
Background technology
The warning lamp that is used for public security special vehicle roof at present mostly is to realize alarm function by single light flash, its structure is in the alternate translucent lampshade of microscler red indigo plant several direct current incandescent lamp bulbs to be installed, be provided with reflective focusing rotating disk around every bulb, during use, bulb is long bright, the rotating disk rotation, thus flicker effect produced.The shortcoming that this warning lamp exists is that scintillation light intensity is low, and particularly in the misty rain sky, light penetration power is not enough, and the caution distance is near relatively; And power consumption is big, and service life is also shorter.Existing advanced warning lamp is to adopt the flash lamp that electronics discharges and recharges and the light-emitting diode panel form of high brightness, it is low to preferably resolve scintillation light intensity like this, the problem that propagation distance is short, but they still have only single flashing function, and do not show the function of alert status or intention.
Summary of the invention
The purpose of this utility model is for special vehicle especially police vehicle provides a kind of good flicker effect that not only has, and the warning lamp of energy while display working condition or intention.
Technical solution of the present utility model is: it comprises lampshade, it is characterized in that being separately installed with in the lampshade dot matrix LEDs plate towards preceding cover and back cover, the high brightness LED any literal or graphical set, random color that connects into the dot matrix way arrangement is installed on this matrix plate, and this dot matrix LEDs plate is connected with flicker, normal bright control circuit control box by cable.
The utility model outward appearance except that lampshade adopt full impregnated bright, traditional warning lamp basically identical that install at others and existing police car top, but because its light source has adopted high brightness luminescent two utmost points and electronic control circuit, not only improved scintillation intensity greatly and make the caution system can more effective work under bad weather conditions such as misty rain, but also the high brightness LED of available different colours is set at various specific literal, the graphical set intention of display working condition clearly, and reaches different caution effects.The utility model sound construction, manipulate easy, power consumptive province, long service life.

Fig. 1 is the utility model general structure schematic diagram.
Fig. 2 is dot matrix LEDs plate circuit control principle figure of the present utility model.
The specific embodiment
Embodiment, the lampshade 1 of warning lamp adopts transparent material to make, its external form is consistent with existing common warning lamp, the middle part is equipped with loudspeaker 4 in the lampshade 1, arrange totally four blocks of dot matrix LEDs plates 2 and on the lampshade floor board framing, be separately installed with front and back two, select for use a part of light emitting diode 3 can connect to form " public security patrol " on the matrix plate, printed words such as " POLICE " demonstration, and formation is set the illuminating circuit group, be called for short the setting group, all the other light emitting diodes 3 are called for short the back of the body and show group, these the two groups luminous tubes that can adopt different colours respectively as backing illuminating circuit group, partly use blueness as font, all the other are with red.The setting group of matrix plate 2 and the back of the body show group and are connected with circuit 7 in flicker, the normal bright control circuit control box 6 with lead 5 respectively, circuit board 7 by power line 8 with (+12V) dc source is connected, and is respectively equipped with siren switch 9 and warning lamp switch 10 on the guidance panel.Circuit on the circuit board 7 by power supply stabilization circuit and word show/the blink states conversion control circuit forms.Power supply stabilization circuit is made up of circuit of three-terminal voltage-stabilizing integrated IC1 (7805) and voltage-stabiliser tube W1, capacitor C 4 and triode BG1, the former supplies control circuit work by output+5V dc source, and latter's output+2~3V dc source is for the work of dot matrix LEDs plate (concrete voltage is fixed according to the diode of employing); And word shows/the blink states conversion control circuit comprises the generation pulse signal part is made up of resistance R 1, R2, capacitor C 2 and IC 2 (555) and partly is made up of the output circuit that triode BG2 and relay J 01 are formed, changed by K switch 2 realization states.Wherein the power supply of transporting to triode BG2 and relay J 01 control triode BG1 output through resistance R 5 by resistance R 1, R2, capacitor C 2 and IC 2 (555) generation pulse signals is the pulse power.When K switch 2 in " A " when position, setting group power input connects the pulse power of being sent here by relay J 01, the back of the body shows group power input ground connection, this moment, warning lamp was the flicker of setting group, the back of the body shows group and does not work, and is usual patrol state; When K switch 2 in " B " when position, setting group power input connects the voltage-stabilized power supply of being sent here by triode GB1, the back of the body shows the group power input and connects the pulse power of being sent here by relay J 01, this moment, warning lamp was setting group Chang Liang, the back of the body shows the group flicker, is the state of emergency.
