The backlight of electronic product such as mobile phone, MP3 realized that by the LED on the circuit board two kinds of implementations are arranged at present: (1) evenly places a plurality of LED background lights in the key area of circuit board, and the light direct irradiation that sends forms backlight on button.(2) place the luminous LED-backlit lamp of several side at the edge of the key area of circuit board, place light guide plate below button, the side-emitting led light that sends is transmitted to each button below by the leaded light groove on the light guide plate, is radiated on the button equably.

The LED background light that uses provides power supply and current circuit by the cabling on the circuit board for it at present, the press key lamp of electronic product such as mobile phone, MP3 probably need consume tens milliamperes of electric currents, if long-time use will be shortened the service time of electronic products such as mobile phone, MP3 to a great extent.

Summary of the invention

In view of this, the utility model embodiment provides a kind of energy-conservation device backlight and electronic product to reach purpose of energy saving.

For solving the problems of the technologies described above, the utility model embodiment provides a kind of energy-conservation device backlight, comprising:

Guidance panel: be used for the keying input information on the pressing operation panel;

Light emitting module: luminous when being used for described button and pushing;

Connect shell fragment: being connected or disconnection of described connection shell fragment and electron product circuit plate controlled in the deformation that produces when being used to utilize described button to push;

Correspondingly, the utility model embodiment also provides a kind of energy-conservation electronic product backlight, comprising:

Connect shell fragment: being connected or disconnection of described connection shell fragment and circuit board controlled in the deformation that produces when being used to utilize described button to push;

Embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment is clearer, below with reference to accompanying drawing and for two example two, the utility model is further described.

First embodiment that the utility model provides is a kind of energy-conservation device backlight, comprising:

Among Fig. 1, guidance panel 101, it is used for the keying input information on the pressing operation panel 101, described information is character or command information, described guidance panel 101 comprises button, and described guidance panel 101 is made of light transmissive material, and the bottom of described button directly contacts or indirect contact with light emitting module 102, when the user presses described button, pressure is acted on light emitting module 102 by button;

Light emitting module 102, it is luminous when pressing that it is used for described button, described light emitting module 102 is made up of the push type luminescent material, when the pressure of pressing generation when described button acts on the described push type luminescent material, described push type luminescent material sends the light of particular color, pressure is passed to connect shell fragment 103 simultaneously;

Connect shell fragment 103, described connection shell fragment 103 constitutes by having deformation recovery capability metal, or nonmetally constitute and cover copper on the surface of connecting portion by what have a deformation recovery capability, when the pressure that produces when described button is pressed is passed on the described connection shell fragment 103 by described light emitting module 102, deformation take place and are connected with the circuit board corresponding site in described connection shell fragment 103, thus when described circuit board transmits described button and presses the signal of generation;
