Compared with the prior art, the illumination unit adjustment system and method can automatically adjust the color brightness of the illumination unit according to the ambient brightness of the mobile terminal, thereby enhancing the user experience on the one hand, and saving on the other hand. Power consumption.

As shown in FIG. 1, it is an operating environment diagram of the illumination unit adjustment system (hereinafter simply referred to as "adjustment system") of the present invention. In this embodiment, the adjustment system 2 is operated in the mobile terminal 1. The mobile terminal 1 can be an electronic device such as a mobile phone or a personal digital assistant (PDA). In this embodiment, the mobile terminal 1 further includes a light sensor 3, a light emitting unit 4, a memory 5, and a processor 6. The light sensor 3 is used to instantly sense the brightness value of the environment in which the mobile terminal 1 is located.

In this embodiment, the lighting unit 4 may be an indicator light for indicating the status of the mobile terminal 1 (for example, having an unread text message). The light emitting unit 4 may include a plurality of LEDs (Light Emitting Diode) modules. In order to enable the light emitting unit 4 to emit a plurality of light colors, the light emitting unit 4 includes the first LED module 41 and the first embodiment. The two LED modules 42 and the third LED module 43 are described as an example. The first LED module 41 may be a red LED, the second LED module 42 may be a green LED, and the third LED module 43 may be a blue LED module. Different color colors can be mixed by the LED modules 41, 42, 43.

It should be noted that the number of the LED modules included in the light-emitting unit 4 and the color of the emitted light may be changed according to actual needs of the user. The number of LED modules is also not limited to the three.

In this embodiment, the adjusting system 2 is configured to: when the mobile terminal 1 turns on the light emitting unit 4, according to the brightness value of the environment where the mobile terminal 1 is sensed by the light sensor 3 The color brightness of the light emitting unit 4 is adjusted.

The memory 5 is used to store various materials, such as a stylized code for storing the adjustment system 2. In this embodiment, the memory 5 is further configured to store an illumination parameter configuration table (refer to FIG. 4) that is preset by the adjustment system 2 according to a user's needs.

In this embodiment, the adjustment system 2 can be divided into one or more modules, and the one or more modules are stored in the memory 5 and executed by the processor 6 to complete the present invention. The function. For example, referring to FIG. 2, the adjustment system 2 is divided into a setup module 21, an open module 22, an acquisition module 23, a determination module 24, and an adjustment module 25. The module referred to in the present invention is a program segment for performing a specific function, and the functions of each module will be specifically described in the flowchart of FIG.

3 is a flow chart of a preferred embodiment of the method for adjusting the illumination unit of the present invention.

In step S1, the setting module 21 presets an illumination parameter configuration table according to the needs of the user, and sets one of the illumination parameters as the default illumination parameter of the illumination unit 4, and stores the illumination parameter configuration table in the memory 5. . The illumination parameter configuration table defines illumination parameters of the illumination unit 4 when the mobile terminal 1 is at different ambient brightness (see FIG. 4). The illumination parameters of the light-emitting unit 4 are current values flowing to the LED modules 41, 42, 43 respectively.

For example, a certain lighting parameter in the lighting parameter configuration table may be set as a default lighting parameter when the lighting unit 4 indicates that the mobile terminal 1 has an unread text message, such as “flowing the lighting parameter to the LED module 41 , 42 , The current value of 43 is set to the default illumination parameter of 4 mA, 2 mA, 2 mA, respectively, that is, the illumination unit 4 is set to emit a strong orange-red light by default to indicate that the mobile terminal 1 has an unread text message.

It should be noted that, in this embodiment, the illumination parameters of the light-emitting unit 4 when the mobile terminal 1 is in different ambient brightness values may be respectively set according to the RGB three-color current ratio defined by the human eye color. The lighting parameter configuration table is described.

For example, in the embodiment, the illumination parameter configuration table defines current values of the LED modules 41, 42, 43 flowing to the light-emitting unit 4 when the ambient brightness value is 0 to 75 luxes. 2 mA, 1 mA, and 1.2 mA, respectively, that is, the light-emitting unit 4 is configured to emit orange-red light with weak brightness when the mobile terminal 1 is in a dark environment, and the orange-red light with weak brightness is the user. A color that can be sensitively perceived in the case of a dark ambient light.

For example, when the ambient brightness value is 75-180 luxes, the currents flowing to the LED modules 41, 42, and 43 of the light-emitting unit 4 are respectively 4 mA, 2 mA, and 2 mA, that is, the light-emitting unit 4 is disposed. When the ambient brightness is bright, the mobile terminal 1 emits orange-red light with strong brightness, and the orange-red light with strong brightness is a light color that can be sensitively perceived by the user when the ambient brightness is bright.

It should be noted that the illumination parameter configuration table of the above-mentioned light-emitting unit 4 can be specifically set according to the needs of the user. For example, when the user wants the light-emitting unit 4 to emit only one light color, such as blue light, the user can only use the third LED. The current of the module 43 is configured to configure the currents of the first LED module 41 and the second LED module 42 to be zero.

In step S2, when the mobile terminal 1 needs to turn on the lighting unit 4 to indicate the state of the mobile terminal 1, the opening module 22 turns on the lighting unit 4 according to the set default lighting parameter.

For example, when the mobile terminal 1 has an unread text message, the opening module 22 is based on the preset default lighting parameters (ie, the current flowing to the LED modules 41, 42, 43 respectively is 4 mA, 2 mA, 2 mA) to turn on the LED modules 41, 42, 43 so that the light-emitting unit 4 emits a bright orange-red light to remind the user that the mobile terminal 1 has an unread text message.

In step S3, the acquisition module 23 acquires the ambient brightness value sensed by the light sensor 3 when the mobile terminal 1 turns on the light emitting unit 4. For example, the ambient brightness value sensed by the light sensor 3 is 70 luxes.

In step S4, the determination module 24 determines whether the acquired illumination parameter in the illumination parameter configuration table is consistent with the current illumination parameter of the illumination unit 4, and if not, performs step S5, if the process is consistent. Then, returning to step S3, the ambient brightness value sensed by the light sensor 3 is continuously acquired.

For example, the determining module 24 determines that the acquired ambient brightness value 70luxes in the lighting parameter configuration table is "the current flowing to the LED modules 41, 42, 43 is 2 mA, 1 mA, 1.2 mA, respectively" The current illumination parameter of the light-emitting unit 4, that is, "the current flowing to the LED modules 41, 42, 43 is 4 mA, 2 mA, 2 mA, respectively" does not coincide with this, and step S5 is performed at this time.

In step S5, the adjustment module 25 adjusts the illumination parameter of the illumination unit 4 to the illumination parameter corresponding to the acquired ambient brightness value in the illumination parameter configuration table, thereby adjusting the color brightness of the illumination unit 4.

For example, the adjustment module 25 can adjust the illumination parameter of the illumination unit 4 to the corresponding illumination parameter of the acquired ambient brightness value 70Luxes in the illumination parameter configuration table through the I2C bus bar. The current values of the LED modules 41, 42, and 43 are adjusted to 2 mA, 1 mA, and 1.2 mA, respectively. That is, the color brightness of the light-emitting unit 4 is adjusted from orange-red light having a strong brightness to orange-red light having a weak brightness. Since the weaker orange-red light is a light color that the user can feel sensitively when the ambient brightness is dark (the ambient brightness value is 70 Luxes), by adjusting the color brightness of the light-emitting unit 4, on the one hand It can be ensured that the lighting unit 4 can play the role of reminding the user, and on the other hand, the power consumption is adjusted.

It can be seen from the flow steps of the present invention that the illumination parameters of the illumination unit 4 can be set in advance according to the needs of the user, and different illumination parameters can be configured under different ambient brightness, when the mobile terminal 1 turns on the illumination. When the unit 4 indicates the state, the present invention can automatically adjust the color brightness of the light emitting unit 4 according to different ambient brightness of the mobile terminal 1. On the other hand, the user's experience is enhanced due to the change of the color brightness. Compared with the prior art, the light-emitting unit 4 indicates the state of the mobile terminal 1 with a fixed color brightness, which further saves power.
