Description

Flash unit

Technical field

The utility model about a kind of optical devices, especially about a kind of optical devices being applied to flashlamp.

Background technology

In the information age now, the mankind grow with each passing day for the dependence of electronic installation, and in response to the high speed of electronic product now, high-effect and lightening requirement, the portable electronic devices of tool camera function gradually becomes main flow, and become indispensable instrument in modern's life, make the use of various image capture unit (such as traditional camera, digital camera, have the mobile phone etc. of image acquisition function) more and more extensive.For promoting the shoot function of image capture unit, usually needing arranging one flash unit in image capture unit, being used to when image capture unit is taken, provide light filling effect to make up the situation of ambient light deficiency, and then obtain image more clearly.

Refer to Fig. 1, it is the structural representation of existing flash unit.Flash unit 1 comprises flash-o-lens (flashlens) 12 and using light emitting diode as the light emitting source 11 providing light beam L1, and flash-o-lens 12 has the structure 121 of sawtooth like shape close to the one side of light emitting source 11; Wherein, the light beam L1 that light emitting source 11 provides can first outwards export after flash-o-lens 12, and the structure 121 of sawtooth like shape is the direct of travel in order to change through light beam L1 wherein, the light beam L1* outwards exported is spread, to reach the effect to environment light-supplementing.

But, existing flash unit 1 light filling poor effect, it is uneven that reason is that the light beam L1* after via flash-o-lens 12 spreads, make to be caught light region in brightness be everywhere not quite similar; Be with, many technical schemes are suggested to improve above-mentioned defect, such as more evenly good after outside output through changing light beam that the structure of flash-o-lens itself enables light emitting source provide, it is disclosed by U.S. Patent application US2012/0176801 publication number and U.S. Patent application US2014/0226299 publication number.Only, flash-o-lens itself often has outward appearance to limit, therefore excessively curved surface is not used, and current trend is combined with mechanism by flash-o-lens, the mechanism combined with flash-o-lens thus just needs the breasting face corresponding with flash-o-lens, thus cause the optical surface of flash-o-lens to be restricted, otherwise just cannot be combined with breasting face.Therefore under the limitation required with process technique in appearance and modeling and laser intensity, the flash-o-lens after change structure often has limitation, is not easily accepted or volume production by market, and its thickness cannot effectively reduce, and does not also meet light, thin, short and small trend.

In addition, also have and be suggested to the technical scheme increasing light uniformity coefficient through arranging optical scattering structure on the shell (such as phone housing) of position corresponding to flash-o-lens, it is disclosed by U.S. Patent application US2012/0018322 publication number, but because shell makes its precision cannot match with flash-o-lens because of processing procedure limitation, therefore the effect brought is still limited.Moreover the mode arranging slidingtype diffuser plate before United States Patent (USP) US5477292 notification number is set forth in flash unit is to the uniformity coefficient after promoting light beam and outwards exporting, but this will increase the complexity of mechanism and the integral thickness of flash unit.

In addition, the demand of user to image quality grows with each passing day, and the color (so-called colour temperature) of the image obtained after therefore expecting to utilize image capture unit to take should be true to nature as much as possible, therefore also more exquisite to the colour temperature fidelity of flashlamp.Furthermore, because the flash unit 1 shown in Fig. 1 only has single light emitting source 11, i.e. so-called single sudden strain of a muscle (singleflash), therefore the color degree of saturation of the light filling of flash unit 1 pair of environment has not enough situation, and cannot adjust colour temperature.In view of this, second light emitting source (two sudden strain of a muscle) and even the 3rd light emitting source (three dodge) that can provide the light filling of different-colour also can be set again, to improve above-mentioned defect in existing flash unit.But because the multiple light emitting sources in flash unit not have same luminescent center, therefore how can to reach homogenising in the mixing of colour temperature and the mixing of light filling intensity be a problem urgently to be resolved hurrily.

Again, light emitting source in general flash unit, as light emitting diode (LED), in its light beam provided, to account for the proportion of its light source frequency spectrum not low for the part of blue light, but because blue light is not often accepted by user or environment, therefore how by blue light components, the light beam be converted into by user or environment accept also becomes important topic.

According to above explanation, existing flash unit has the space of improvement.
