Abstract
The utility model provides a kind of LED flash lamp module, comprises PCB, is integrated in the LED flashlamp array in PCB, it is characterized in that, described LED flashlamp array is made up of the LED flashlamp that many lens focus are different.LED flash lamp module provided by the utility model is by the LED flashlamp with different optical performance is carried out simple module array combination, realizes the function of focusing; Different effects of taking pictures can be realized, as annular LED flash lamp module by the arrangement mode of different LED flashlamp.LED flash lamp module structure provided by the utility model is simple, is easy to be widely used in the carry-on equipment such as mobile phone.
Description
Technical field
The utility model relates to a kind of flashlamp, particularly a kind of LED flash lamp module of focus adjustable.
Background technology
Current flashlamp is generally divided into gas flashlamp and LED flashlamp, and the mode of operation of gas flashlamp is only the flash of light of trigger pulse formula, namely reaches glittering state instantaneously from the state of not working.The light lightened like this has very strong pungency to the eyes of people and nerve, belongs to light pollution, can cause certain potential safety hazard.As new type light source, LED flashlamp progressively substitutes gas flashlamp, and LED flashlamp has following advantage by contrast: can continuous illumination, and luminescence process easily controls, and power consumption is little, can save a large amount of electric energy.
Mobile phone, digital camera coordinating generally by camera and LED flashlamp, realize the function of taking pictures night.Existing LED flashlamp is all the camera lens adopting fixed focal length, and that is, LED flashlamp hot spot is in use changeless.Currently available technology also has zoom lens, but this kind of camera lens is bulky, complex structure, is not suitable for the carry-on equipment such as mobile phone.
Utility model content
For the deficiencies in the prior art, it is simple that the purpose of this utility model is to provide a kind of structure, the LED flash lamp module that lens focus is adjustable.
To achieve these goals, the utility model is by the following technical solutions: a kind of LED flash lamp module, comprise PCB, be integrated in the LED flashlamp array in PCB, described LED flashlamp array is made up of the LED flashlamp that many lens focus are different.
Preferably, the implementation of the LED flashlamp that described lens focus is different is that LED lamp bead is identical, and secondary optical lens is different.
Preferably, the implementation of the LED flashlamp that described lens focus is different is that LED lamp bead is identical, and secondary optical lens is identical, but relative position is different.
Preferably, the implementation of the LED flashlamp that described lens focus is different is the encapsulating structure difference of LED lamp bead, and secondary optical lens is identical.
Preferably, the implementation of the LED flashlamp that described lens focus is different is that LED lamp bead is different, and secondary optical lens is different.
Preferably, the arrangement mode of described LED flashlamp array is linear pattern, annular or rectangle.
LED flash lamp module provided by the utility model is by the LED flashlamp with different optical performance is carried out simple module array combination, realizes the function of focusing; Different effects of taking pictures can be realized by the arrangement mode of different LED flashlamp, as annular LED flash lamp module, 360 degree can be realized and evenly take.The structure of this LED flash lamp module is simple, is easy to be widely used in the carry-on equipment such as mobile phone.
Accompanying drawing explanation
Fig. 1 is embodiment one structural representation of the utility model LED flash lamp module;
Fig. 2 is embodiment two structural representation of the utility model LED flash lamp module;
Fig. 3 is the front view of the embodiment three of the utility model LED flash lamp module.
Embodiment
Embodiment one
The utility model provides a kind of LED flash lamp module, as shown in Figure 1, in PCB 1, linear pattern fixes the different LED lamp bead of two hot spots, a secondary optical lens 4 is installed respectively above two LED lamp pearls, these two secondary optical lens 4 are identical, the LED flashlamp that final formation two lens focus are different, the LED lamp bead that wherein two hot spots are different is LED lamp bead 2 and LED lamp bead 3.Now define the light beam degree (FOV) of flashlamp by hot spot homogeneity 30%, the beam angle of the LED that LED lamp bead 2 and secondary optical lens 4 are formed is 90 degree, and the beam angle of the LED that LED lamp bead 3 and secondary optical lens 4 are formed is 45 degree.In the process used, camera lens zoom information passes to this LED flash lamp module by sensing circuit, change the light intensity ratio of LED lamp bead 2 and LED lamp bead 3, realize this module beam angle the change of 45 degree to 90 degree, finally realize the synchronous zoom of flash lamp module and camera lens.
Embodiment two
As shown in Figure 2, be the structural representation of the utility model LED flash lamp module.Wherein in PCB 1, linear pattern fixes two identical LED lamp bead 5, installs ordinary optical lens 6 and soft light optical lens 7 above two LED lamp pearls respectively, finally forms the different LED flash lamp module of two lens focus.
Embodiment three
The LED lamp bead 8 that fixing many optical properties of annular are different in PCB, above annular LED lamp pearl, install annular secondary optical lens 9, the annular LED flash lamp module that final formation many lens focus are different, its front view as shown in Figure 3.This ring flash module not only can realize focusing function, and can provide very uniform light when taking pictures, and make the photo effect taken more clear, the light of 360 degree ensure that the spreadability of whole camera lens.
The above; be only the embodiment in the utility model; but protection domain of the present utility model is not limited thereto; in the technical scope that any people being familiar with this technology is disclosed in the utility model, the conversion that can expect easily or replace all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
