Relevant detailed description of the present utility model and technology contents, it is as follows to see also following detailed description and description of drawings, and accompanying drawing and detailed description are as illustrative purposes only, are not to be used to limit the utility model.
Cooperate and consult Fig. 1 and Fig. 2, be respectively light source module three-dimensional exploded view of the present utility model and partial sectional view.This light source module is in order to use with a camera module 50 collocation, and specifically, this light source module is transferred on an imaging lens 52 of camera module 50, so that the light source of camera module 50 when the close-range photography to be provided.In the present embodiment, camera module 50 is that a commercially available digital camera is an example, does not then limit with this during actual enforcement.
This light source module comprises an adapter 12, a sleeve 14, one first luminescence unit 16 and one second luminescence unit 18.Adapter 12 is undertaken in camera module 50, and the mode of accepting of adapter 12 and camera module 50 can be for being spirally connected or magnet absorption; Adapter 12 has one provides the perforation 122 of imaging lens in 52 through its, and perforation 122 is by an axis I, and the internal face that adapter 12 correspondences are penetrated with perforation 122 places is provided with an internal thread 124, and an optical axis of its axis I and imaging lens 52 coincides.
When reality is used, when the camera module 52 that undertakes this light source module carries out filming image, camera module 50 can support the top of standing on a surperficial S (as shown in Figure 2) by the support of sleeve 14, and the user need not application of force handheld camera module 50, so can carry out the shooting of surperficial S like a cork.
Consult Fig. 2 again, part by 16 outgoing of first light emitting diode is passed through the light that surperficial S reflects via light and another part that a surperficial S reflects, can promptly can directly not enter imaging lens 52 via these sleeve 14 outside transmissions of using light-transmitting materials to make by first light emitting diode, 16 emergent raies.Therefore, even if surperficial S is for level and smooth and when having the lower material of contrast such as fingerprint on it, this material only can make part light enter imaging lens 52 in the mode of scattering, avoiding the photo-sensitive cell overexposure of camera module internal, and causes the unclear situation of image fog to take place.Wherein the light that sent of first light emitting diode 16 can be infrared light, visible light or ultraviolet light, with the corresponding matching various materials that throw light on; Its mid-infrared light and ultraviolet light can be corresponding at article with infrared light mark and ultraviolet light mark, as bill, forge the detection of function; In addition, ultraviolet light can cooperate with fluorescein stain and reaches fluoroscopic examination, and its range of application for example is the detection of the trickle slight crack in metal surface.
Consult Fig. 1 and Fig. 2 again, second luminescence unit 18 is positioned at sleeve 14, and be positioned at the rear of first luminescence unit 16, and second luminescence unit 18 is towards the I direction emergent ray that parallels to the axis, promptly the light emission direction of second luminescence unit 18 is roughly parallel to axis I, to produce a coaxial light source, coaxial light source is directly towards the object emergent ray, to illuminate this object effectively, side by side, light by the object reflection is covered with in the photo-sensitive cell of camera module 50 inside, can finish the shooting of arbitrary small part of object effectively.Second luminescence unit 18 comprises one second endless belt 182 and at least one second light emitting diode, 184, the second luminescence units 184 are arranged at second endless belt 182.In the present embodiment, second endless belt 182 is a flexible circuit board, so that after second light emitting diode 184 is mounted thereon, can bends easily and be placed in the sleeve 14.The light that second light emitting diode 184 is sent can be infrared light, visible light or ultraviolet light, with corresponding matching illumination different material; Its mid-infrared light and ultraviolet light can be corresponding at article with infrared light mark and ultraviolet light mark, as bill, forge the detection of function; In addition, ultraviolet light can cooperate with fluorescein stain and reaches fluoroscopic examination, and its range of application for example is the detection of the trickle slight crack in metal surface.
Moreover, this light source module of the present utility model also includes a switch element 20, switch element 20 is arranged at sleeve 14 peripheries and is electrically connected at first luminescence unit 16 and second luminescence unit 18, and the user can select to light first luminescence unit 16 or second luminescence unit 18 according to the characteristic of object.Side by side, switch element 20 has the function of regulating first luminescence unit 16 and second luminescence unit, 18 luminosity, and the user can regulate optimum luminosity according to the difference of shooting condition and take.
This light source module of the present utility model also further includes a power supply unit 30, power supply unit 30 is placed in adapter 12 and is electrically connected at first luminescence unit 16 and second luminescence unit 18, required electric power provides when providing first luminescence unit 16 and second luminescence unit 18 luminous, for instance, power supply unit 30 can comprise at least one battery.
Cooperate and to consult Fig. 3, be the partial sectional view of the light source module of the utility model second embodiment.This light source module roughly light source module with Fig. 1 and Fig. 2 is identical, difference is, the leading section 142 of sleeve 14 rearward end 144 relatively moves forward and backward along axis I direction, specifically, leading section 142 is bolted on this rearward end 144, therefore, when needs cooperate the actual light mathematic(al) parameter of camera module 50 and adjust camera module 50 and this subject apart from the time, can rotate leading section 142 relatively by relative rearward end 144, and change the entire length of sleeve 14 easily.
Cooperate and consult Fig. 4, be the light source module three-dimensional exploded view of the utility model the 3rd embodiment.This light source module roughly light source module with Fig. 1 and Fig. 2 is identical, difference is, this camera has omitted adapter 12 with the light source module, sleeve 14 directly is undertaken on the imaging lens 52 of camera module 50, and comes first luminescence unit 16 and second luminescence unit 18 are powered by camera module 50 power supplys own.
The above; it only is preferred embodiment of the present utility model; therefore be not and limit protection domain of the present utility model,, all should be contained within the scope of patent protection of the present utility model so the equivalence of using the utility model instructions and accompanying drawing to do such as changes with modification etc.
