Abstract

The utility model relates to a supervision card for a taxi driver, which is composed of an electroluminescent screen and a transparent piece, wherein, the transparent piece is printed with a full name, a name, a photo, and a code mark of the supervision card or job number, an organization, a supervision telephone and number, and contents for supervising relevant things, foreign translation, etc. The electroluminescent screen uses a DC source of the vehicle to cause a specially make inverter to emit light. The gang control can be carried out via the opening and closing of front vehicle lamp and indicating lamps of empty vehicles. Switch can be individually arranged to control. Supervision contents on the supervision card can be clearly seen in the evening or dark environment. The utility model is good for supervision and complaint to improve the quality of service.

Description

Taxi driver's supervisory card

The utility model relates to a kind of solid plate light source, belongs to light source technology and display technique field, and the particularly at night a kind of or taxi that also can show content of supervision in darker environment is with driver's supervisory card (hereinafter to be referred as supervisory card).

The solid plate light source adopts electroluminescence screen (hereinafter to be referred as the EL screen) light source.This light source have power consumptive province, luminous soft, visual angle greatly, not dazzling characteristics, itself and the slide with supervisory card content cooperate as supervisory card of the present utility model.

The purpose of this utility model is to provide a kind of supervisory card, even not only by day at night or in the darker environment, luminous with the EL screen by having supervisory card title, name, photograph, numbering or job number, unit, complaint telephone and number and supervising relevant other guide and the slide of all content of supervision such as foreign language translation clearly shows to reach; Because not luminous, cause the content of supervision that can not see supervisory card in evening or the darker environment clearly to change driver's supervisory card that original taxi uses, the effect that does not have supervision and complain influences the situation of service quality.

The purpose of this utility model realizes by following manner:

Supervisory card is made of EL screen, slide and shell with content of supervision, and shell one side has display window, and slide inserts or be placed in this window place, and the light-emitting area of EL screen is close to slide, uses DC power supply on the car by inverter and luminous.EL screen in the supervisory card is luminous controlled by headlight and opening or closing of empty wagons identification light, and this control mode has mandatory; Also can switch be set separately controls.Two kinds of control modes all can prolong the serviceable life of supervisory card.

Below in conjunction with accompanying drawing the utility model is described in further detail, wherein:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a circuit diagram of the present utility model, and L represents that EL screen, N represent inverter, K ₁K ₂Expression switch, S ₁Expression headlight, S ₂Expression empty wagons identification light and E represent automobile-used DC power supply.

Embodiment

Referring to Fig. 1 and Fig. 2, supervisory card by EL shield L, slide 1 and shell with content of supervision constitute, shell has display window.EL screen L mainly is made of transparency electrode 2, electroluminescence layer 3, insulation reflection horizon 4 and back electrode 5.Lead-in wire and the lead-in wire of the back electrode 5 and output terminal of inverter N of the transparency electrode 2 on the EL screen L is connected, and the input end of inverter N passes through K switch ₂With headlight S ₁Be connected in parallel.EL screen L's is whether luminous by headlight S ₁K switch ₁With empty wagons identification light S ₂K ₂Control.

The slide with content of supervision 1 of adapted adopts the thin slice of plastics matter or other suitable material, and content of supervision is in accordance with regulations made in advance, and the area size is identical with the light-emitting area of EL screen L, adopts the display window place that inserts or be installed in shell.Inverter N makes for supervisory card is special.

Claims

1, a kind of taxi driver's supervisory card, it comprises that EL screen L, the slide 1 with content of supervision and shell constitute, shell has display window.EL screen L with the DC power supply E on the car by inverter N and luminous; It is characterized in that:

(1) said EL screen L is mainly by transparent electroplax 2, electroluminescence layer 3, and insulation reflection horizon 4 and back electrode 5 constitute;

(2) said slide 1 adopts the thin slice of plastics matter or other suitable material to make in advance according to content of supervision:

(3) said inverter N is the HF voltage way of output, shields luminous optimum efficiency to reach EL.

2, according to right 1 described taxi driver's supervisory card, the described EL screen of its feature L is connected with the output terminal of inverter N, the input end of inverter N is in parallel with headlight by K switch 2, and EL screen L's is whether luminous by the K switch 1 of headlight S1 and K switch 2 controls of empty wagons identification light S2.
