Abstract

Electronic equipment according to the present invention includes: an illumination unit that is mounted so as to form the surface of a housing and is capable of transmitting a light from inside the housing to outside; and a light-emitting unit that emits a light to the illumination unit from inside the housing and is mounted inside the housing. Then, the light-emitting unit includes a plurality of RGB LEDs (Light Emitting Diodes) that can emit red, green and blue lights, and the respective RGB LEDs are arranged so that part of a light emitted to the illumination unit by a predetermined one of the RGB LEDs and part of a light emitted to the illumination unit by another of the RGB LEDs overlap each other before entering the illumination unit.

First claim

The invention claimed is:

1. A mobile phone comprising:
an illumination unit that is mounted so as to form a surface of a housing of the mobile phones and is capable of transmitting a light from inside the housing to outside; and
a light-emitting unit that emits a light to the illumination unit from inside the housing and is mounted inside the housing,
wherein the light-emitting unit includes a plurality of RGB LEDs (Light Emitting Diodes) that can emit red, green and blue lights, and the respective RGB LEDs are arranged such that illumination directions of the RGB LEDs are diagonal to an illuminated face of the illumination unit so that part of a light emitted to the illumination unit by a predetermined one of the RGB LEDs and part of a light emitted to the illumination unit by another of the RGB LEDs overlap each other before entering the illumination unit, and
the respective RGB LEDs are arranged on a first side of a blocking object formed inside the housing so that lights emitted by the respective RGB LEDs shine beyond the blocking object and illuminate and illuminated face located on a second side of the blocking object.

2. The mobile phone according to claim 1 , wherein the respective RGB LEDs are arranged so that lights emitted to the illumination unit by the respective RGB LEDs overlaps each other by about one third to about one half.

3. The mobile phone according to claim 2 , wherein the respective RGB LEDs are arranged so that about one third of a light emitted to the illumination unit by a predetermined RGB LED, only on one side of which another of the RGB LEDs is located, of the RGB LEDs overlaps part of a light emitted to the illumination unit by the other RGB LED.

4. The mobile phone according to claim 2 , wherein the respective RGB LEDs are arranged so that about one half of a light emitted to the illumination unit by a predetermined RGB LED, on both sides of which others of the RGB LEDs are located, of the RGB LEDs overlaps part of respective lights emitted to the illumination unit by the other RGB LEDs that are located on both the sides of the predetermined RGB LED.

5. The mobile phone according to claim 1 , wherein the respective RGB LEDs can be arranged in a state that LEDs emitting respective colors of lights are placed in any order.

6. The mobile phone according to claim 1 , wherein the respective RGB LEDs are arranged so that a close portion of the illumination unit to a predetermined member located inside the housing can be illuminated with lights emitted by the RGB LEDs from inside the housing.
