Description

Light-emitting device

Technical field

The utility model relates to a kind of light-emitting device, and it is preferable to aim to provide an illumination effect, and configurable in the electrical part product, as the light-emitting device on mobile phone or the personal digital assistant.

Background technology

On the phone luminous suggestion device is housed generally in action at present, its light emitting source is light emitting diode (LED) or cold light film.Luminous mechanism mode on the present phone in action has:

1, directly use light-emitting device or see through mist light glass, transparent, translucent material is luminous, its effect is can be directly luminous, the all existing angle of the light that this light emitting diode sends penetrates (about about 120 degree), so luminous scope can only be confined to the limited scope in light emitting diode top.

2, see through light guide plate, leaded light refers to that indirect material is luminous, this technology can prolong luminous distance, but because light guide plate can not be crooked, to the moulding restriction of having made a living, and the brightness of leaded light paper is not enough, causes illumination effect obvious inadequately.

The utility model content

In view of this, the purpose of this utility model is to provide an illumination effect preferable, and configurable in the electrical part product, as the light-emitting device on mobile phone or the individual action assistant.

The solution of the utility model " light-emitting device ", it includes lamp guide and light source at least, first, second, third and fourth side that its lamp guide has a bottom surface, an end face relative with this bottom surface and connects bottom surface and end face, light source then are arranged at wherein a side, wherein appoint two sides, wherein wantonly three sides or four sides.

The beneficial effects of the utility model are: after the light that makes light source enters lamp guide by the side of lamp guide, can make whole lamp guide luminous, to reach preferable illumination effect, whole light-emitting device can be disposed on the electrical part product, and reach the function of special light-emitting zone or illumination.
