Mobile phone with desk lamp with dimmer switch
Technical field:
The utility model relates to a kind of mobile phone with desk lamp with dimmer switch, and it belongs to communication technique field, particularly a kind of mobile phone that illumination functions can be arranged.
Background technology:
Along with popularizing gradually of mobile phone, the user is also vigorous gradually for the additional function demand of mobile phone, mobile phone that can night illumination more and more is subjected to user's favor, particularly from the mobile phone of main regulation flashlight brightness, not only the user can control the power of brightness according to the needs of oneself, and also favourable energy savings meets the theory of energy-conserving and environment-protective and low-carbon (LC) life.But the mobile phone that has illumination functions at present only is to rely on cellular phone power supplies directly to power, and can not control the brightness of illuminating lamp as required, and the energy consumption of battery of mobile phone is big like this, and the suitable cycle of battery of mobile phone is shorter.
Summary of the invention
The purpose of this utility model is to provide a kind of mobile phone with desk lamp with dimmer switch that can independently debug lighting brightness according to surrounding enviroment.
The purpose of this utility model is achieved in that
A kind of mobile phone with desk lamp with dimmer switch, it comprises hand-set host body and the illuminating lamp that is arranged on the mobile phone main body, the power line of described illuminating lamp is connected with battery of mobile phone, it is characterized in that connecting the power management chip that can realize voltage-regulation on described battery of mobile phone, described power management chip is connected on the illuminating lamp; Described mobile phone master chip is provided with a pulse-width modulation circuit that is connected and can realizes lighting brightness with illuminating lamp.
Described pulse-width modulation circuit comprises triode and adjustable resistance that a high frequency is connected.
The utility model is by being provided with control circuit unit on the mobile phone master chip, not only supported the illumination functions of mobile phone, also can support what brightness intelligence was regulated, the software interface intelligence that makes the user pass through mobile phone is regulated the brightness of torch lamp, and realized the reasonable use of cellular phone power supplies, the consumption of having saved battery of mobile phone.

Embodiment:
Below in conjunction with accompanying drawing 1, Fig. 2 and Fig. 3, the utility model is further detailed:
In the present embodiment, the utility model comprises hand-set host body 1 and the illuminating lamp 2 that is arranged on the mobile phone main body, the power supply of described illuminating lamp 2 is connected with battery of mobile phone, in order to realize the purpose of this utility model, connect the power management chip that can realize voltage-regulation on described battery of mobile phone, described power management chip is connected on the illuminating lamp; Described mobile phone master chip is provided with a pulse-width modulation circuit that is connected and can realizes lighting brightness with illuminating lamp.Described pulse-width modulation circuit comprises triode and adjustable resistance R that a high frequency is connected.Mobile phone master chip of the present utility model is existing mobile phone master chip, as the MTK6255 chip for cell phone; The power management chip that is connected on the battery of mobile phone is MTK6305.
During use of the present utility model, the user can open illumination functions by the mobile phone operation interface, this moment, mobile phone CPU was by special-purpose control interface control power management chip, power management chip interior lighting circuit carries pulse-width modulation circuit, and can be according to the brightness regulation of the instruction from 1% to 100% of CPU end.
