Hereinafter, the apparatus 100 for changing the shape of the illumination output through the flashlight module included in the rear of the user terminal will be abbreviated as the illumination shape changing apparatus 100 and described.

FIG. 2 is a diagram showing the configuration of an apparatus for changing a shape of lighting output through a flashlight module included in the rear of a user terminal according to the present invention.

The apparatus 100 for changing the lighting shape according to the disclosure may include a flashlight module 1300, a filter module 1400, a user interface 1500, a display 1600, a control unit 1100, and a memory 1200. .

According to one disclosure, the flashlight module 1300 may include a lighting module installed at the rear of the user terminal. The flashlight module 1300 may include at least one LED.

According to one disclosure, the flashlight module 1300 may be provided with at least one, and other mobile devices that provide a camera function in addition to other functions such as digital cameras or smart phones, tablet PCs, personal portable terminals, etc. It can be installed in several different devices such as.

According to the invention, at least one additional emitter is used as a conventional remote communication module, e.g. as a remote control for an external device or with a flash for other communication purposes to convey data or control signals to the external device. . The term "emitted to the environment" means that the light passes through the flash light lens as the final optical element, where the flash light lens can be held by the device, where the flashlight module 1300 is in a housing, or It is installed by the housing itself.

According to one disclosure, the flashlight module 1300 is based on the center LED, the first lens located at the upper end of the center LED, a reflector installed around the first lens and reflecting the light signal incident from the center LED, and the center LED. It characterized in that it comprises a plurality of LED modules arranged in a circle, a focus lens located on the upper portion of the plurality of LED modules, and a plurality of second lenses arranged in a semicircular shape under the plurality of LED modules.

According to one disclosure, in the flashlight module 1300, at least one additional emitter is an infrared emitter, invisible light is infrared light, and invisible light emission direction is an infrared light emission direction, or at least one additional emitter is UV- It is an emitter, and can be provided in such a way that the invisible light is UV-light and the invisible light emission direction is the UV-light emission direction.

The flashlight module 1300 of one disclosure avoids any redundancy of additional emitter systems, for example infrared (IR) or ultraviolet (UV) emitter systems, in mobile devices such as smartphones or tablets. The opening in the mobile device used for the camera flash is simultaneously reused for additional emitters for communication purposes, for example as a remote control typically using infrared light. The claimed assembly only requires providing remote communication (control) capabilities to the additional emitter as an additional hardware component, but the housing of the flashlight module 1300 and the optical lens of the flashlight module 1300 also provide the emitted invisible light. It is used for, in turn, eases assembly and reduces the overall required footprint of a dual function solution. In addition to communication purposes, additional invisible light emitters may be used for inspection purposes, such as near-distance lighting, for example for a counterfeit detector or required to make other UV or IR conversion inks or features visible.

The flashlight module 1300 may be arranged in a device that already has a camera and a flash light lens. In this case the flashlight module 1300 is suitably arranged at a location behind the flash light lens to emit visible light from the flash light emitter as well as invisible light from the additional emitter via the flash light lens.

Alternatively, the flashlight module 1300 comprises a flash light lens arranged at a first distance in front of the flash light emitter to shape the flash light beam emitted from the visible flash light emitter in which the flashlight module 1300 itself Wherein the optical axis is the optical axis of the flash light lens and the position and orientation of the flash light lens is also the invisible light through the flash light lens in the invisible light emission direction in which the additional emitter deviates from the optical axis of the flash light lens. It is suitably adapted to be able to emit. The flashlight module 1300 may be provided in such a way that the first distance is typically 0.3 mm±0.15 mm.

The flashlight module 1300 may be provided in such a way that the flash light lens has a lateral size sufficient to cover the flash light emitter and additional emitter when viewed in a direction parallel to the optical axis of the flash light lens. A sufficiently large lens allows flexible positioning of the additional emitters within the flashlight modules 1300, where the invisible light allows the flash light lens to be formed without any difficulties or additionally required optics to shape the invisible light beam. Can still be released through. In camera flash applications, the lateral size of the flash light lens is generally 2-3 times larger than that of a flash light emitter, for example an LED light source, making it possible to aim the visible light of the camera flash onto the scene being photographed. The flashlight module 1300 may be provided in a manner in which the flash light lens is a Fresnel lens.

According to one disclosure, the flashlight module 1300 is at least an additional emitter (and also the flash light lens is the case of the flashlight module 1300 including a flash light lens) to reduce the invisible light by 30°-80°, preferably. In a manner that is suitably arranged for emission into the environment (after passing through the flash light lens) under an average emission angle α between the optical axis and the invisible light emission direction of 50°-70°, more preferably about 60°. Can be provided. The emission angle of the invisible light makes it possible to control the device while at the same time reliably directing the invisible light to the electronic device for communication with the electronic device from a remote location by means of an invisible light beam, wherein the flashlight module ( 1300) is installed in it. Because the emitted light is not visible, any display solution that controls the orientation of the device holding the flashlight module 1300 during communication is not applicable. Accordingly, a user directing the invisible light beam toward the electronic device must visually direct the invisible light toward the intended direction and adjust the orientation of the flashlight module 1300 accordingly. Therefore, the device holding the flashlight module 1300 should not block the viewing direction. Specified emission angles are used for this purpose. The average emission angle is the average angle of invisible light emitted to the environment from the flash light lens in a given emission cone.

According to one disclosure, the flashlight module 1300 may be provided in such a way that the additional emitter is adapted to provide invisible light of an emission intensity of at least 10 mW/sr to the environment in the invisible light emission direction. The additional emitter can be adapted to provide invisible light with a power of at least 1 mW from the flash light lens in the invisible light emission direction. Typically the invisible light beam propagates with a certain light cone comprising a spacing of different emission angles and an intensity change over emission angles, where the FWHM intensity is distributed over the spacing of emission angles ranging from 20°. About 1 mW/sr is needed to communicate with the electronic device at a distance of about 6 m, where a power of 2 mW/sr is preferred. A much larger distance is undesirable to avoid controlling electronic devices that are not intended to be controlled, for example nearby electronic devices. Invisible light from emitters arranged outside the optical axis passing through conventional flash light lenses typically directs 5% of its power to a target area defined by the average emission angle. A target output power of 2 mW over a distance of 6 m can be easily achieved by, for example, so-called 8 mil IR chips, delivering a total of 50 mW peak output power in remote control protocol pulsed conditions.

The flashlight module 1300 may be provided in a manner in which the second distance is about 0.9 mm to deliver the required power in a desired direction. In general, the term "about" in combination with certain values will mean a spacing around ±30% from a given given value to cover certain adjustment deviations.

Would be the best compromise between the flashlight module 1300 design and the preferred direction of emission from the mobile device.

The flashlight module 1300 may be provided in such a way that the flash light emitter preferably comprises an array of LEDs arranged in a rectangular emission area in a suitable arrangement. LEDs are compact light sources that can be easily controlled. Such an array of emitters provides a flash light beam with a greater intensity and/or a wider emission angle.

In another embodiment, for some of the multiple additional emitters, the second distances are the same, where the other second distances are different. In another embodiment, all the second distances are the same. All these embodiments are directed to holding the device holding the flashlight module 1300 in different orientations that still enable communication with external electronic devices independent of the orientation of the devices holding the flashlight module 1300. This is possible because at least one of the plurality of additional emitters emits its invisible light towards the external electronic device, for example for remote control of the external device.

The flashlight module 1300 can be provided in such a way that the housing holding at least a flash light emitter and an additional emitter is a single piece housing, preferably the housing also holds a flash light lens.
