Abstract
The utility model relates to an automatic luminous display device for an optical control telephone, which is composed of a telephone housing, an external DC battery, a light-sensitive device, a control circuit, a super high brightness luminous diode group, etc. The utility model adopts the external DC battery and super high brightness luminous diodes, so the utility model can provide super high brightness luminous service, a telephone can be beautiful and bright when the telephone is used in dark environment, and the utility model has high enjoying value; the utility model utilizes the characteristics of the light-sensitive device, so the utility model can automatically provide luminous service in dark environment, and the service time of the battery is extended; the utility model has the advantages of simple circuit and low cost, and the utility model effectively increases the grade of the telephone and enhance the purchase desirability of users.
Description
The utility model relates to a kind of display unit, the automatic noctilucence display unit of particularly a kind of light-operated phone.
Luminous tube in the existing telephone noctilucence display unit all is direct power taking sources on the phone exchange line, and electric current is limited to be restricted brightness because of providing; Make its noctilucent function be difficult to performance.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of automatic noctilucence display unit of light-operated phone that the service of super bright noctilucence can just be provided under dark environment automatically is provided.
The purpose of this utility model can reach by following measure: the utility model comprises telephone case, it is characterized in that: also have battery, light-sensitive device, control circuit, super bright light-emitting diode group, light-sensitive device links to each other with the input of control circuit, the output of control circuit links to each other with super bright light-emitting diode group, and battery links to each other with control circuit and super bright light-emitting diode.
The purpose of this utility model can also reach by following measure: light-sensitive device adopts photo resistance R
w, R
wBe loaded on the face-piece of telephone case.Photo resistance R
wOne end and adjustable resistance R
1Join, the base stage of the other end and triode BG is joined, the LED in the collector electrode of BG and the superelevation shell light-emitting diode group
1～LED
6Join.
Fig. 1 is a functional-block diagram of the present utility model;
Fig. 2 is an assembling shape assumption diagram of the present utility model;
Fig. 3 is an electrical schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 2, the utility model is made up of telephone case 1, battery 2, light-sensitive device 3, control circuit 4, super bright light-emitting diode group 5 etc.Photo resistance R
wBe loaded on the face-piece of telephone case 1; Dc-battery 2 is loaded in the telephone case 1, and for circuit provides DC power supply, magnitude of voltage is more than 3 volts.Electronic circuit board and super bright light-emitting diode group 5 are loaded on the position of nearly telephone key-press in the face-piece.
With reference to Fig. 3, control circuit 3 comprises triode BG, adjustable resistance R
1, resistance R
2Deng; Super bright light-emitting diode group 5 adopts super bright LED
1～LED
6Photo resistance R
wOne end and adjustable resistance R
1Join base stage and the resistance R of the other end and triode BG
2Join the collector electrode of BG and LED
1～LED
6Join.Its photo resistance R is being arranged under the environment of light
wResistance is little, not conducting of triode BG, and luminous tube is not luminous; When being under the dark situation; R
wIt is big that resistance becomes, triode BG conducting, LED
1～LED
6Send than high light, the noctilucence service is provided.Adjust adjustable resistance R
1Can obtain under desirable light dark situation, just lighting light-emitting diode group.
The utility model has following advantage compared to existing technology:
1, adopts external direct current pool and super bright light emitting diode, the noctilucence of its super brightness Service can make telephone set bright (when off hook state) extremely attractive in appearance when dark situation uses, Very high ornamental value is arranged.
2, utilize the characteristic of light-sensitive device, just automatic lifting can for the noctilucence service under dark situation Prolong the service time of battery, and circuit is simple, cost is lower, has effectively improved telephone set Class strengthens user's desire to buy.
