Description

Mobile Phone with Emitting Light

The present invention relates to a mobile phone equipped with a light function. More specifically, the present invention relates to a mobile phone equipped with a light function in which a specific portion of the antenna emits light by adding a light emitting function to an arbitrary outer circumferential surface of the mobile phone or an antenna, and the user presses or manipulates a specific key of the mobile phone.

As modern society allows people to use electricity freely, it is being used as an essential energy source for modern life. For example, electricity is required to drive various electronic products used in homes and industrial sites, and electricity is required to generate light for illuminating dark places.

On the other hand, by using such a useful electricity to emit light, the device that illuminates the dark place is collectively called a lighting fixture. Luminaires can be broadly classified into fixed types that can be fixed in a certain place (such as on a wall or desk) and mobile types that can be carried by a person. The most widely used of such portable lighting fixtures will be a flashlight.

In general, the flashlight is small in size, easy to carry, and can be very useful in various cases, such as when working in a basement where no fixed lighting device is installed or when moving a relatively distant place without a light at night. That is, in most cases, the flashlight is carried in consideration of the case where the user needs the flashlight in advance. Therefore, when the user unexpectedly, for example, to open the door or car door in a place where there is no light at night, or in the case of having to find a specific object in a cool room during power outages, the flashlight is not usually carried. You are in a difficult situation. In other words, the flashlight has the advantage of being easy to carry, while the user rarely carries it all the time.

Therefore, in recent years, an improved product in which a light device is attached to writing instruments, such as a ball pen or fountain pen, which can be carried on a daily basis, has been devised, but this requires a separate space for storing a battery or the like for supplying power to the light device. There is a problem. This causes a variety of problems, such as large size of the product and significantly higher manufacturing costs.

In addition, since the lighting device installed in the writing instrument has to be installed in a narrow internal space of the writing instrument, it is very difficult to install a general light bulb, and there is a problem that it is difficult to obtain sufficient illuminance because the LED (Light Emitting Diode) lamp is usually used. . In addition, although writing instruments are small in size and easy to carry compared to general flashlights, there is a disadvantage in that they require considerable attention to carry around at all times.

On the other hand, the rapid development of integrated circuit technology and wireless communication technology has resulted in the creation of mobile phones, which are becoming smaller and more versatile in recent years. Various functions added to the mobile phone include an alarm function for transmitting a ring tone when a user preset time, a voice dial function, a speed dial function, a text message transmission function, and an Internet connection function. Therefore, in addition to the basic voice call function of the mobile phone, the user is carrying a mobile phone at all times due to these various functions.

However, mobile phones that provide such various functions also do not provide a light function that illuminates a dark place. Although light is emitted from a liquid crystal display (LCD) panel (Pannel) of a mobile phone, the light intensity is so weak that only the letters and numbers displayed on the LCD panel can be identified. Therefore, there is a disadvantage in that mobile phones currently distributed cannot obtain flashlight level lights and thus can not perform the function of a flashlight.

In order to solve the above-mentioned disadvantages, the present invention provides a mobile phone equipped with a light function in which a specific part of the antenna emits light by adding a light emitting function to an arbitrary outer circumferential surface of the mobile phone or the antenna by the user pressing or manipulating a specific key of the mobile phone. It aims to provide.

To this end, the present invention, in a mobile phone with an antenna for transmitting and receiving radio signals, a battery for supplying power of a predetermined voltage to the mobile phone, disposed in front of the mobile phone, one or more key buttons for key data input A control unit for controlling the overall operation of the mobile phone by transmitting a control signal in response to data input from the keypad, a light emitting device installed on a part of the mobile phone to emit light according to the control signal, and emitting the light emitting device. It provides a mobile phone with a light function, characterized in that it comprises a ROM in which a predetermined program for storing.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a perspective view showing the appearance of a mobile phone 100 equipped with a light function according to an embodiment of the present invention.

1, the mobile phone 100 according to an embodiment of the present invention displays an earphone 103 for transmitting sound to the front surface 102 of the main body 101, letters, numbers, images, videos, and the like. LCD panel 104, a keypad 106 having a plurality of key buttons 105 for data input, and a microphone 108 for receiving a voice signal are arranged in this order. . In addition, the mobile phone 100 includes a flip 110 hinged to a lower end of the main body 101 and one or more special keys 113 attached to the left and right sides of the main body 101 to protrude. An antenna 114 attached to one side of the upper end of the main body 101 and a light emitting device 116 formed at the end of the antenna 114 to emit light.

On the other hand, the light emitting mechanism 116 may be manufactured integrally with the antenna 114 at the time of manufacturing the mobile phone 100, or may be manufactured separately. In the case of being manufactured separately, there is an advantage in that the light emitting device 116 may not be able to exert its performance due to long-term use, and may be replaced with a new light emitting device 116. It is not replaceable, but it has a merit that looks better than detachable.

On the other hand, the kind of the light emitting device 116 includes a light bulb using a variety of light bulbs such as a reflective light bulb, a sealed beam light bulb, an iodine light bulb, a halogen light bulb, a three-wavelength light bulb, an all-optical light bulb, and an LCD. Of course, the size of the light emitting device 116 may be relatively small enough to be attached or inserted into the antenna 114.

2 is a perspective view showing the appearance of a mobile phone 200 equipped with a light function according to another embodiment of the present invention.

The appearance of the mobile phone 200 illustrated in FIG. 2 is almost similar to that of the mobile phone 200 described with reference to FIG. 1. In FIG. 1, the light emitting device 116 is attached to the antenna 114, but in FIG. 2, the light emitting device 202 is attached to the outer circumferential surface of the upper end of the mobile phone 200 instead of the antenna 204. In FIG. 2, the light emitting device 202 is illustrated as being attached to the outer circumferential surface of the upper end of the mobile phone 200, but may be attached to the outer circumferential surfaces of the lower end, the left side and the right side of the mobile phone 200.

On the other hand, the light emitting mechanism 202 as in Figure 1 will be possible to manufacture a cell phone 200 integral or detachable. However, unlike the attachment to the antenna 114 in FIG. 1, in FIG. 2, when the cross-sectional area where the light emitting device 202 is attached is larger than that of the antenna 114, detachment may not be easy. 220) One piece would be more preferred. In addition, the light emitting device 202 described with reference to FIG. 2 may also use the same kind of light emitting devices as described with reference to FIG. 1.

Meanwhile, according to an embodiment of the present invention, the method of controlling the light emitting devices 116 and 202 described with reference to FIGS. 1 and 2 is the same, so that the method of controlling the light emitting device 116 using the mobile phone 100 illustrated in FIG. I will explain.

According to the embodiment of the present invention, first, the user can emit light by the light emitting mechanism 116 by pressing any special key 113 attached to the left or right outer peripheral surface of the mobile phone (110). The special key 113 according to the embodiment of the present invention may be configured as a push on / push off type or a push on / release off type belonging to a push type. Can be. Therefore, when the special key 113 is a push on / push off type, the light emitting mechanism 116 is repeatedly turned on and off every time the user presses the special key 113 once. If the special key 113 is a push on / release off type, the light emitting device 116 operates while the user presses the special key 113 while the special key 113 is not pressed. Operate off.

Second, the user may operate the key button 105 provided in the keypad 106 to cause the light emitting mechanism 116 to emit light. That is, the user can cause the light emitting mechanism 116 to emit light by inputting one or more specific key buttons 105 in sequence (eg, ＃-> 2-> 2 or *-> 3-> 3). This feature would be very useful in the case of cell phones that do not have a special key 113 on the left or right outer surface of the cell phone.

Third, the user may make the light emitting device 116 emit light by selecting an additional function provided by the mobile phone 110, for example, a 'light function' or an 'emergency lamp function' using the menu selection key button 105 or the like. Here, the 'light function' is a general flashlight function for the user to light up the darkness, the 'emergency light function' is a flashing light fixture 116 blinks at regular intervals to notify other people of the emergency when the user is in an emergency or emergency situation. It means function.

3 is a block diagram briefly illustrating an internal configuration of a mobile phone 100 according to an embodiment of the present invention.

An internal configuration of the mobile phone 100 according to the embodiment of the present invention includes a control unit 300, a key input unit 310, a power supply unit 330, an antenna unit 340, a light emitting device 350, and a ROM. . In addition, the voice processing unit 320 may be further provided to control the light emission of the light emitting mechanism 350 by the voice input. Of course, some of the voice processing unit 320 provided in some of the mobile phones 100 may be used.

Referring to FIG. 1, the control unit 300 functions to control the overall operation of the mobile phone 100 using key data or voice data input from the key input unit 310 or the voice input unit 320. In general, a microcontroller or the like is included.

The key input unit 310 receives key data from a plurality of key buttons 105 arranged on the keypad 106 and transmits the key data to the controller 300.

The voice processing unit 320 receives a voice input from the microphone 108 and performs voice processing, digital signal processing, voice recognition, and the like to recognize voice data, and includes a voice recognition dedicated chip. Therefore, when the user pronounces, for example, "light" or "emergency lamp" through the microphone 108 of the mobile phone 100, the light emitting device 350 emits light. At present, since a speech recognition technology applied to a mobile phone is a well-known technique well known to those skilled in the art, a detailed description thereof will be omitted.

The power supply unit 330 functions to supply power for driving the mobile phone 100.

The antenna unit 340 includes a light function according to the present invention in addition to the general function such as transmission and reception of radio waves. The antenna unit 340 according to the embodiment of the present invention includes an AND gate 342 to perform a write function, and a light emitting device 350 is connected to a signal output terminal of the AND gate 342. . When the signal related to the write function is input from the key input unit 310 or the voice processing unit 320, the antenna unit 340 of the light emitting device 350 responds to the control signals A and B transmitted from the control unit 300. An enable signal C for emitting light is generated.

The ROM 360 stores a predetermined program for emitting the light emitting device 350 according to the embodiment of the present invention. That is, when the user selects the 'light function' through the predetermined menu key of the keypad 106, the controller 300 drives a predetermined program stored in the ROM 360 to the LCD panel 104. Display the Image menu.

Referring to the light emitting process of the light emitting device 350 according to an embodiment of the present invention, when the user inputs the key data or voice signal related to the light function using the key button 105 or the microphone 108, the control unit 300 ) Receives the processed signal from the key input unit 310 or the voice processing unit 320. The control unit 300 receiving a signal from the key input unit 310 or the voice processing unit 320 generates high level control signals A and B having a logic value of '1'. The AND gate 342 generates a high level enable signal C for emitting the light emitting device 350 when the control signals A and B transmitted from the controller 300 are all at a high level.

On the other hand, the control unit 300, if the control signal (A, B) is both at a high level, that is, the state that the light emitting mechanism 350 is emitting light for more than a predetermined period of time, the control signal (A, B) is a logic value ' Transition to Low Level, which is 0 '. In general, the mobile phone 100 operates by receiving power from the battery 112. When the light emitting device 350 emits light for a long time, the power of the entire mobile phone 100 is generally due to the high power consumption of the light emitting device 350. This is because the consumption is very large.

Of course, the light emission time (setting period) may be predetermined for each mode or may be arbitrarily selected by the user.

If the user inputs key data or voice signal related to the emergency light function other than the light function described above, the control unit 300 alternates between the high level control signal A and the high level and the low level at regular intervals. Generate signal B. Therefore, the enable signal C output from the AND gate 342 also has the same frequency as the control signal B output from the control unit 300 and transitions to the high level and the low level. The light emitting device 350 functions as a kind of emergency light that is repeatedly turned on and off at a predetermined number of times in response to the enabled enable signal C.

In FIG. 3, the case where the light emitting device 350 is attached to the antenna 114 is described. However, the same principle may be applied to the case where the light emitting device 350 is attached to the outer circumferential surface of the mobile phone 200 as illustrated in FIG. 2.

The above description is merely illustrative of the present invention, and those skilled in the art to which the present invention pertains will be capable of various modifications without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present specification are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited thereto. The scope of the present invention should be construed by the claims below, and all the technologies within the equivalent scope should be construed as being included in the scope of the present invention.

As described above, in the past, it was very cumbersome for a user to always carry a flashlight in case of emergency, but according to the present invention, a light function is added to a mobile phone which is almost always carried by general users, which is useful at night or in dark places. Will be available.

In addition to the general light function, the mobile phone may further include an emergency light function, so that the user may use it as a tool to notify others of his / her location in case of emergency.
