Abstract
The utility model discloses an earphone with a luminescent indication device, and the earphone comprises an earphone shell, wherein the earphone shell is provided with light emitting diodes (LEDs), each LED is electrically connected with a control circuit, and the control circuit is electrically connected with a power supply. By adopting a light-control switch of a photosensitive resistance, luminance needed by switching on the circuit is preset, the power supply can be automatically switched on in weak light environment and other environments, the LEDs on the earphone shell emit light and are uniformly distributed along the circumferential direction of an earphone shell handle part, so that the light can be seen from different angles, the earphone is striking, when the earphone is required to use, the earphone can be rapidly discovered through the light, the defect that the conventional earphone is difficult to find can be avoided, and convenience in use can be realized. The power can be cut off by the light-control switch in a completely dark environment or in an environment with strong light, so that the LEDs are stopped emitting light continuously, and the waste of the electric energy can be avoided.
Description
Technical field
The utility model relates to a kind of earphone that has light-emitting device instructions.
Background technology
In the bad environment of lighting condition, such as in car, because light is bright inadequately; When need using earphone owing to do not have luminous indicating lamp on the earphone, the color of adding earphone in most cases with car in environment consistent; So the difficulty of searching is made troubles to people.
The utility model content
The utility model technical problem to be solved provides a kind of earphone that has light-emitting device instructions can be in low light environment luminous, easy to use automatically.
For solving the problems of the technologies described above; The technical scheme of the utility model is: have the earphone of light-emitting device instructions, comprise ear casing, on the said ear casing light-emitting diode is installed; Said light-emitting diode is electrically connected with control circuit, and said control circuit is electrically connected with power supply.
As optimized technical scheme, said control circuit is for adopting the light-operated switch of photo resistance.
As optimized technical scheme, said light-emitting diode is three, and said light-emitting diode along the circumferential direction is distributed on the outer peripheral face of said ear casing shank.
Owing to adopted technique scheme, have the earphone of light-emitting device instructions, comprise ear casing, on the said ear casing light-emitting diode is installed, said light-emitting diode is electrically connected with control circuit, and said control circuit is electrically connected with power supply.Adopt the light-operated switch of photo resistance can preestablish the required brightness of turning circuit, in car, wait in the low light environment turn-on power automatically, the lumination of light emitting diode on the ear casing; And light-emitting diode circumferentially evenly distributes along the ear casing shank, can see light from all angles, makes earphone become eye-catching; When people use earphone at needs; Can find earphone rapidly through light, avoid earphone in the past to look for the defective of difficulty, easy to use.Light-operated switch can be cut off the electricity supply in the environment that dark or light are stronger fully, and the continuation that stops said light-emitting diode is luminous, and electric energy avoids waste.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: the 1-ear casing; The 2-light-emitting diode; The 3-light-operated switch.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.In the detailed description below, some example embodiment of the utility model has only been described through the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation of spirit that does not depart from the utility model and scope, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection range of claim.
As depicted in figs. 1 and 2, have the earphone of light-emitting device instructions, comprise ear casing 1, on the said ear casing 1 light-emitting diode 2 is installed, said light-emitting diode 2 is electrically connected with control circuit, and said control circuit is electrically connected with power supply.
Said control circuit is for adopting the light-operated switch 3 of photo resistance, because of the circuit structure and the operation principle of said light-operated switch 3 belongs to known technology, repeats no more here, also do not give illustrating among the figure.
Said light-operated switch 3 is set in and waits in the low light environment turn-on power automatically in the car, makes said light-emitting diode 2 luminous, and in the stronger environment of complete dark or light, can cut off the electricity supply, and the continuation that stops said light-emitting diode 2 is luminous.
Said light-emitting diode 2 is three, and said light-emitting diode 2 along the circumferential direction is distributed on the outer peripheral face of said ear casing 1 shank.
This arrangement of light-emitting diode, no matter which kind of spatial attitude earphone is in, and always within people's sight, can there be luminous dead angle in said light-emitting diode.
The conduction mode of light-operated switch comprises that self-locking is bright and excites, secretly excites and accurate bright excite etc. that the light-operated switch that adopts in the present embodiment is the light-operated switch of accurate bright mode of excitation, and the brightness range that excites of setting meets the light conditions in the car; In all not conductings under the situation preferably of fully dark or light, after night, people left car, in the car fully dark get off; This moment, light-operated switch can make circuit break off; Stop light-emitting diode and continue luminously, when perhaps light was stronger by day, light-operated switch also can open circuit; Do not allow meaningless luminous of light-emitting diode, avoided the waste electric energy.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
Claims (3)
