Light Emitting Diode Microarray Flash

Abstract

The invention discloses a light-emitting diode micro-array flashlight, which is applied to a mobile phone to generate an adjustable lighting source or project an image, which includes a micro-light-emitting diode array module, a light-mixing optical module and an optical module. The micro light emitting diode array module is arranged in the casing of the mobile phone to generate patterned image light sources. The light-mixing optical module and the optical module are detachably arranged on the outer surface of the casing of the mobile phone, and are used to receive the image light source emitted by the micro-LED array module and respectively irradiate the light source or project it into an image. The invention utilizes a light-emitting diode array chip combined with an external light-mixing optical module to produce a flashlight with adjustable light type and color. By replacing the light-mixing optical module with an optical module, the image light source is projected into an image, so that the mobile phone has a projection function.

Description

technical field [0001] The present invention relates to a flashlight, and in particular to a light-emitting diode micro-array flashlight applied to a smart phone and using a micro-light-emitting diode array module. Background technique [0002] Along with the change of life style, the situation that utilizes mobile phone as shooting and recording device is more and more prevalent, because the portable characteristic of mobile phone makes people can record scenery, portrait and the scene that sees anytime and anywhere. However, with the increase in popularity, the requirements for various scene performance characteristics according to each shooting environment and display requirements have also increased. [0003] Although it is now possible to use subsequent photo editing software to modify the captured images or videos to achieve various situational performances, this method of using post-production to obtain the desired image often needs to be manually adjusted one by one....

AI Technical Summary

Problems solved by technology

Because the existing LED fill light of smartphones is a single light source, it is impossible to adjust the warm or cool color light according to the shooting environment requirements, which leads to the situation that the follow-up still needs to be artificially modified by retouching software.

Although some existing smartphones have developed a two-color light source for the fill light to complement the modulation function of the color temperature, in situations that require special light sources, such as: Apple light for selfies or dark green light for creating fear effects, What's more, to further highlight the theme, the use of strong and weak light sources in different positions, or the double halo effect required for special situations, cannot easily achieve the needs of the situation.

[0005] On the other hand, the use of smart phones as a digital medium for audio-visual entertainment and office discussions has become more and more popular. However, due to the small size of smart phones, it is not enough to provide multiple people to read through the display screen on the mobile phone. , thus requiring the use of projection technology to produce larger image presentations

[0006] Existing projector modules use components such as backlights and optical filters to produce the required images. If you want to use the same technology on a mobile phone so that the mobile phone can directly project, the small size of the mobile phone makes the heat dissipation difficult. The problem will be highlighted, and the power required by the general projection module is too large for the mobile phone, and it is not convenient to realize the projection function on the mobile phone

[0007] It can be seen that the above-mentioned prior art still has many deficiencies, is not a good design, and needs to be improved urgently.
