Abstract
The utility model relates to a road sign board for buses and trolley buses. The utility model comprises a box body, a surface pattern of the box body, a plurality of luminous diodes and a power supply control part, wherein, the box body is connected with a bus body, and the surface pattern of the box body is provided with a light transmission part. A plurality of luminous diodes are connected in series into groups, and the luminous diodes are connected with the power supply control part in parallel; so power supply can be matched with the voltage drop of the luminous diodes. All luminous diodes and the power supply control part are assembled on a printed circuit board. By the arrangement of all luminous diodes, the printed circuit board just corresponds to the light transmission part of the surface pattern of the box body when the printed circuit board is assembled in the box body. The utility model has the advantages of simple structure and strong practicability.
Description
The utility model relates to a kind of public vapour, electric car road number plate, particularly relates to a kind of a kind of novel, energy-conservation, road luminous display unit efficiently that is applied on city motor bus, the electric car.
At present, the road number plate of most public vapour, electric car all can not be luminous, this to night the rider extremely inconvenient, make people not judge whether the city motor bus taken advantage of for oneself going in advance from head-on sailing the automobile that comes prepare so that carry out by bus.As masses' the important vehicle, city motor bus need assemble the night lights sign.Adorned the trackless trolley car of the number plate sign of passing by on one's way owing to adopt filament lamp as light source, the power consumption height, the life-span is short.
The purpose of this utility model is the above-mentioned defective that overcomes existing road number plate, provide a kind of can active illuminating, life-span length, the public vapour of power consumptive province, electric car road number plate.
For achieving the above object, the utility model provides a kind of public vapour, electric car road number plate, it comprises one and car body bonded assembly casing, tank surface pattern (2) with a light transmission part, a plurality of light-emitting diodes (1) and a power control part branch (V1), these a plurality of light-emitting diodes (1) are connected in groups and so that the tube voltage drop of power supply and light-emitting diode in parallel with this power control part branch (V1) is complementary, each light-emitting diode (1) and power control part branch are assemblied on the printed circuit board, and just the arranging when making in this printed circuit board (PCB) is assemblied in casing (3) corresponding to the light transmission part of tank surface pattern (2) of each light-emitting diode.
According to the road number plate of the utility model manufacturing, owing to adopt light-emitting diode as light source, can active illuminating, thereby distinguish it is city motor bus beyond can being 100 meters, and about 60 meters, can see the road trade mark clearly, and reliable operation, life-span is long, and no-failure operation can be more than 5 years.Owing to adopt luminescent device efficiently, power consumption generally can be about 3 watts.In addition, when light-emitting diode adopts double-colored (for example red and green) or three looks (for example red, green and blue), can show different colors and face the demonstration of glimmering when entering the station in different occasions according to the operation needs of automobile.And when a plurality of city motor buss travelled on same circuit, the car that can stipulate easily not go the same way number adopted different Show Colors, more helps distinguishing.In addition, this road number plate compact conformation is attractive in appearance, practical.
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described.It is determinate to be to be understood that these specifically describe right and wrong, and these purpose of description are in order more to be expressly understood embodiment of the present utility model.In the accompanying drawing:
Fig. 1 is the schematic perspective view of road of the present utility model number plate;
Fig. 2 is the electrical schematic diagram of road of the present utility model number plate.
At first, please refer to Fig. 1, it represents the road number plate schematic perspective view of a preferred embodiment of the present utility model.This road number plate roughly comprises 3, one tank surface patterns 2 of a casing and a plurality of light-emitting diode 1 that is distributed in the light transmission part of pattern 2.Wherein casing 3 adopts metal plastic-blasting or plastic injection-moulded forming, and is firm and attractive in appearance, and it can be fixed or fixed with magnetic force by the appropriate section of screw and car body.Tank surface pattern 2 can be formed through computer carving by the clear sheets such as for example organism glass of overlay film, remove the visuals of overlay film like this through engraving, and for example " 386 " among Fig. 1 are printing opacity.Preferably the color contrast of this light transmission part and remainder is very strong, and when not needing lumination of light emitting diode, when for example travelled daytime, this road number plate can be used as similar common road number plate and uses like this.This tank surface pattern 2 and casing 3 sealings (anti-rainwater) are connected or constitute one, light-emitting diode 1 can be welded on the circuit card (not shown), can make things convenient for circuit to connect like this, and in place fixedly the time in casing when circuit card, light-emitting diode 1 is just corresponding with the light transmission part (" 386 ") of tank surface pattern 2.
Please refer to Fig. 2 then, the electrical connection schematic diagram of its expression light-emitting diode 1 on circuit card.Light-emitting diode (LED) 1 can adopt superhigh brightness LED, carries out dot matrix according to road number plate pattern form and size and arranges (see figure 1).According to the tube voltage drop of LED, each LED (L1, L2 ..., tube voltage drop LN5) for example is 2 to 21V, can adopt 6 to be one group and to be in series so, to reach the about 12V of general automobile storage battery voltage.Each is organized light-emitting diode and is connected in parallel on the power supply.The represented part of V1 is the power control part branch among Fig. 2, and it generally can be stable-pressure device, is about to automobile power source and supplies with LED through voltage stabilizing.If Alternating Current Power Supply or other non-matching voltage are arranged, it can change into the rectifying and voltage-stabilizing device, and the constant voltage power suspply of 1 2V is supplied with LED.C1 and C2 among Fig. 2 are respectively cond, when on the automobile noise jamming being arranged, can play the effect of filtering.Vin and Vout represent the voltage input and output side respectively, and GND represents ground terminal.
Although described a preferred embodiment of the present utility model in conjunction with the accompanying drawings, be on this basis can make much improved.For example light-emitting diode can adopt the red and green color diode, thereby also introduces the control corresponding part in the control power unit V1 of LED, can realize at least that like this redness, green and yellow different colours show.Introduce redness, green and blue LED and realize that the demonstration of multiple color also is feasible.Can partly make adjustment and realize glimmering in light emitting control and show that this can provide a kind of information of rider and realize safe effect when pulling in and setting off.The circuit problem that above-mentioned these display mode control aspects may run into can be solved by the instruction of the related circuit control part of the light emitting diode (LED) display screen that generally adopts, and when it be applied on city motor bus and the electric car time, a kind of special fresh effect is provided.Automatic light-operated circuit can also be introduced, when the same day is subduing like this, the luminous operation of LED road number plate can be automatically made.
Should be appreciated that those skilled in the art can also make multiple correction and remodeling according to above-mentioned instruction.The utility model intention is included in the various road number plates that belong to the different variations of claim and equivalent thereof in the open scope.
