Problems solved by technology

Existing patent applications related to lighting mobile phones are all simple circuits that use load switches to directly control light-emitting elements. It is not suitable to use this circuit for mobile phones, because the design concept of modern mobile phones is: use semiconductor chips to replace load switches , use the trigger signal to realize the switching function, for example, the power-on and power-off functions of all mobile phones are realized through the trigger signal

Embodiment Construction

[0009] First, put the reflective metal tube (1-2) tightly on the high-brightness light-emitting diode LED (1-1), and put the assembled lighting source (1), lighting adjustment integrated circuit (2), button (K) It is welded on the mobile phone circuit board (5), and an illumination control button K (3) is arranged at an appropriate position of the mobile phone casing (4).

[0010] When the lighting control button K (3) is pressed, the bistable trigger circuit (2-1) flips over and outputs a high level, and the current adjustment circuit (2-2) receives an instruction to enter the working state, and the high-brightness light-emitting diode LED (1 -1) Glow. With the length of the pressing time, the output current changes steplessly from 1 to 30 mA, and it is completed within 3 seconds. When it reaches 30 mA, it locks. No matter how long the pressing time is, the working current will not exceed 30 mA. . Release the button K (3) when the appropriate light is reached, the circuit (...

Abstract

The invention uses a lighting regulation IC to control the high-brightness light-emitting diode. The light regulation IC is composed of bistable trigger circuit and current regulation circuit, and its output current can be steplessly tuned within range of 1-30 MA to meet different requirement of illumination.

Description

Technical field [0001] The invention belongs to the technical field of communication and relates to an illuminating mobile phone with adjustable light intensity. technical background [0002] At present, there is no mobile phone that can be used for lighting on the market. Existing patent applications related to lighting mobile phones are all simple circuits that use load switches to directly control light-emitting elements. It is not suitable to use this circuit for mobile phones, because the design concept of modern mobile phones is: use semiconductor chips to replace load switches , use the trigger signal to realize the switch function, for example, the power-on and power-off functions of all mobile phones are realized through the trigger signal. Contents of the invention [0003] The invention provides an illuminating mobile phone with adjustable light intensity, which increases the range of use of the mobile phone and is ready for emergencies. [0004] The technical...
