Problems solved by technology

[0004] However, the light irradiation device described in Patent Document 1 has a structure in which the irradiation directions of light from a plurality of light sources are changed, and there is a problem that it is difficult to obtain a uniform amount of light in the light irradiation range.
[0005] Also, when using a camera to take pictures and illuminate the subject with light, if the light irradiation range is smaller than the photographic angle of view, the light cannot be irradiated on the entire subject; if the light irradiation range is larger than the photographic angle of view, then the light will be redundant. Power is wasted due to diffusion, and at the same time, it causes discomfort to the surroundings due to light leakage

Embodiment Construction

[0047] Below, referring to the attached Figure 1 to Figure 7 , the first embodiment of the present invention will be described in detail. The light irradiation device 1 in this embodiment is as follows Figure 7 A light irradiation device for an optical zoom camera 4 incorporated in a cellular phone 2 is shown. When photographing with the optical zoom camera 4, the light irradiation device irradiates light to the photographed subject in a dark place as so-called flash.

[0048] like figure 1 and figure 2 As shown, the light irradiation device 1 has: a yoke 3 as a fixed body; an irradiation lens support body 7 with an irradiation lens 6 mounted on its inner circumference; frame 8 and front spring 9; and base 5 and rear spring 11 arranged on the yoke 3 at the rear side of the illuminating lens 6 in the optical axis direction (hereinafter referred to as the rear side). A spacer (insulator) 17 is disposed between the rear spring 11 and the yoke 3 . The light source body 10...

Abstract

The invention provides a light irradiating device which can increase or decrease the light irradiation range with a simple structure, a camera device and a mobile terminal device with a camera. The light irradiating device 1 provided in the invention comprises a driving unit which movably supports an irradiating lens support body 7 of an irradiating lens 6. The driving unit comprises coils 15 which are equipped on the periphery of the irradiating lens support body 7; and magnets 13 equipped on an iron 3 and opposed to the periphery face of the coils 15. The range of the irradiation towards an irradiated object is increased or decreased by moving the irradiating lens support body 7 along the optical axis direction through the electromagnetic force after the coils 15 are electrified.

Description

technical field [0001] The present invention relates to a light irradiation device for irradiating light on an object to be irradiated, a camera device having the light irradiation device, and a mobile terminal device with a camera. Background technique [0002] Patent Document 1 (Patent Publication No. JP2007-47706) discloses a light irradiation device that drives a light source support by a drive unit to change the irradiation direction of light from a plurality of light sources. The technique described in this patent document 1 changes the irradiation range and light distribution characteristic to the object to be irradiated by changing the irradiation direction of light of a plurality of light sources. [0003] Also, Patent Document 2 (Patent Publication No. JP2007-53840) discloses a compact camera mounted in a mobile phone, and the compact camera is provided with an optical zoom function. [0004] However, the light irradiation device described in Patent Document 1 has...
