Description

INDUSTRIAL APPLICABILITY The present invention is used for portable electronic products, has low power consumption, is compact and lightweight, is close to a natural light source, is easy on the human eye, has an irregular shape with fragility, and emits light from the entire surface. Regarding the flash lighting device of the diode.

The evolution of portable electronic products is rapid, and the functions from early laptop computers to smartphones are evolving day by day, and they have not only wireless communication but also camera and video functions. In particular, with the advent of social networking services and social networking application programs, the vast majority of users of portable electronic products are using camera and video features, uploading photos and videos to social networking services. .. For this reason, the functionality and quality of cameras and videos are important for electronic products.

However, the camera lenses of early mobile phones were not equipped with flashlights, and it was not possible to take clear pictures in places where the brightness was insufficient. As light emitting diode technology grows day by day, light emitting diodes are placed beside the lens of mobile phones and used as flashlights, which are generally configurable with or without flash. be.
When a flashlight is used for shooting, the flashlight of the light emitting diode consumes a certain amount of power of the mobile phone. In other words, when a conventional light emitting diode is used as a flashlight, the power of the mobile phone itself will be used up if it is used many times. Furthermore, since the light source of the light emitting diode is a momentary point emission, the light source complementing effect is limited, and the light source is supplemented only at the moment of the flash.
Further, since the color temperature of the light emitting diode and the chromaticity of the spectrum are both different from those of the solar light source, the light source can be complemented, but the color is lost and it is unnatural. Moreover, since the light emitting diode has a complicated structure and does not have a self-luminous property, it is necessary to add a module, so that the thickness of the member for mounting the light emitting diode must be increased, and the weight and thickness must be increased. It led to an increase. In addition, the manufacturing process of the light emitting diode is complicated and difficult to install, so that the manufacturing cost increases, and therefore it cannot be said to be the most preferable light source. In addition, most of the raw materials of conventional light emitting diodes are natural resources such as rare earths and inorganic elements, and continuing to consume natural resources has a problem from the viewpoint of environmental protection and natural resource protection.

On the other hand, the light emitting diode installed in the mobile phone can also be used as a flashlight, but as mentioned above, since the light emitting diode consumes power, the mobile phone and the light emitting diode are mounted even if it is used for a short time. It consumes a lot of power from the electronic device, and if the user does not charge it frequently, it cannot be used continuously.
Also, the brightness of a single light emitting diode in a mobile phone could not achieve the best effect of lighting, and the range of lighting was also considerably limited. Furthermore, since the point emission of the light emitting diode is too strong, the pupil contracts momentarily when viewed directly with the naked eye, leaving shadows and afterimages, which leads to lens imbalance and retina damage over a long period of time, improving eyesight and health. Harmed. Notably, light emitting diodes are not the best light source, and the blue light generated in the spectrum often damages the naked eye.

Therefore, the present inventor considers that the above-mentioned drawbacks can be improved, and as a result of repeated diligent studies, he / she has come up with a proposal of the present invention for effectively improving the above-mentioned problems with a rational design.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a flash lighting device used for electronic equipment in order to solve the above problems. That is, in photography by electronic equipment, it provides a light source complementary action by self-luminous instantaneous light emission or continuous light emission, which is surface emission with low power consumption, and prolongs the continuous use time of the electric power of the electronic equipment. Further, the flash lighting device according to the present invention uses an organic light emitting diode as a light emitting material, has wireless transmission and charging functions, controls the spectrum curve of the three primary color spectra by remote control of electronic equipment, and is a light source closest to natural light. Also has a shape such as regular, irregular, or curved depending on the design.

The flash lighting device used in the electronic equipment according to the present invention for solving the above-mentioned problems and achieving the above-mentioned object has a connection unit electrically connected to the electronic equipment and one side surface of the connection unit. It comprises at least one organic light emitting diode unit that is installed and electrically connected to the electronic equipment by the connection unit, where the organic light emitting diode unit is controlled and activated by the electronic equipment and is an environmental light source. It is characterized by supplementing the shortage of LEDs.

In the flash illuminating device according to the present invention, an organic light emitting diode unit and a connection unit are combined and installed in an electronic facility or used independently, and the flash illuminating device emits light instantaneously or continuously under the control of the electronic equipment. .. It has the characteristics of high reaction speed, low power consumption, full-scale emission, and curvability. With conventional magnesium flashlights or light emitting diodes, the reaction speed is slow and the light source cannot be complemented immediately, the power consumption of electronic equipment is large, and because of point emission, only a local minute light source can be provided, and the structure of the light emitting diode element. Effectively solves various drawbacks such as thickening.

Be done. The organic light emitting layer 33 includes at least the three primary color spectra of the red region 331, the green region 332, and the blue region 333, and the regions of the three primary color spectra are mixed to generate white light closest to natural light.

In this preferred embodiment, the connection unit 2 has a plate shape and is mainly mounted on the organic light emitting diode unit 3 and serves as a medium for transmitting an electric signal to the electronic equipment 5.
