Description
Technical field
The present invention relates to a kind of wearing in head and the convenient head lamp that carries out the light source zoom, particularly a kind ofly come the displacement of electronic adjustment dolly camera device by induction installation, reach the head lamp device of convenient toggle lights zoom.
Background technology
When people carry out activity in the place of night or light deficiency; for want of light guides direction; so usually can utilize flashlight to come when auxiliary illuminations; yet vacate the people that both hands carry out work or other affairs for needs; for example mining site workman, night the mountain forest person of patrolling and guarding or other related work personnel; can wear the head lamp on the crown this moment; not only solved required lighting problem; also so that these a little personnel can be more convenient in work; therefore head lamp has just replaced flashlight, becomes people's best selection in night insufficient light situation.
Although the appearance of head lamp, efficiently solve people and can vacate both hands, deal with the work or carry out the problem of other affairs, but traditional head lamp is on light source design, it all is the mode that adopts fixed focal length, make light source by the past front irradiation of the mode that reflects, and under this kind design, it only has the function of light illumination, need to concentrate light source irradiation a bit if run into, or when wanting to utilize the light source of diffusion type to shine certain whole regional extent, because of the restriction on traditional headlamp designs, cause it to carry out the light source zoom in response to varying environment, therefore, it function just occurs in the use and does not apply denouncing of using.
In order to solve the problem that traditional head lamp light source can't zoom, begin to have the varifocal Improvement type head lamp of manufacturer's research and development optical assembly, such as US Patent 11/662,309 patent application case, it is in order to solve the in the past deposited situation about using of traditional head lamp function, conceive the improvement light source zoom head lamp Patent Case, when if this patent is pointed out to need to adjust the light source focal length, then can rotate or the housing of pull light-emitting device with manual mode, make light-emitting device along with housing carries out displacement, and then reach the effect of adjusting the light source focal length, but under this kind design, if the user works half, when temporary needs is adjusted the light source focal length, just can produce following problem:
1. may speckle with in oily matter or the hand in user's hand and still have gloves on, if directly remove to adjust head lamp with hand, might cause light source to be stained with dirty via the hand contact, and the brightness of remote-effects light source, therefore also may cause being stained with on head or the head lamp surface and affix oil stain, and indirectly allow the user be infected maybe need to expend time in the probability that cleans to increase.
Moreover, all similar traditional mechanical switch mode of operation of quoting case as proof of existing headlight switch needs to go it is pulled with hand, control its switch, but the user also increases the difficulty that switch is sought relatively in the insufficient light situation, and the inconvenience that causes the user to operate.
Therefore, in order to address the above problem a little, when user's wish is adjusted the light source focal length, often need remove first the oily matter in the hand or gloves are removed, or because can not find switch, and produce in a rush situation, thereby cause the user in operational inconvenience, and therefore, the light source zoom head lamp after the improvement, being subject to still needs in operation by manually controlling, and therefore still has in the use and need treat improved problem points.
In view of this, the inventor improves the shortcoming of its manual operation light source zoom inconvenience in order to promote the competitiveness of light source zoom head lamp, drops into especially the design of the present invention's " convenient zoom lens control device of head lamp ", hope is by characteristics of the present invention, and then promotes its usability industrially.
