Description

Battery with Flash {BATTERY COMPRISING A FLASH}

The present invention relates to a battery for supplying power to a wireless communication device or a mobile phone, and more particularly to a battery provided with a flash to emit light by applying power to the light emitting diode provided in the battery.

The flash is usually stored in a certain space in the room, and it is common to find and use it in the storage space when lighting is needed, such as when a power failure occurs or when going to a dark place.

However, since the flash is not frequently used and is inconvenient to carry, the user does not always carry it, so there is a problem in that it cannot be used immediately when it is necessary to illuminate the surroundings urgently.

In particular, when looking for a keyhole in a dark place, or when looking for an object, there is a problem that the efficiency is inferior in using the flash because there are many cases that do not have a flash.

Therefore, in recent years, a small flash, which is easy to carry by the user, has been introduced, but this also has not increased in use due to the small need for carrying all the time.

In addition, when the flash is not used for a long time, there is a problem that the battery cannot be used even when there is a flash when the battery is discharged and needs to be used.

On the other hand, mobile phones and wireless communication devices are small in volume and easy to carry, and their use is rapidly increasing in recent years because of the characteristics of being able to talk with the other party anywhere regardless of the place.

In addition, in recent years, cameras and camcorders have been added to provide a more realistic screen. To this end, the LCD screen of a wireless communication device or a mobile phone is changed to color, and the resolution is continuously increasing. Such a liquid crystal screen is generally provided with a backlight on its rear surface, and emits light from the backlight using battery power so that characters or screens formed by the liquid crystal appear by the light.

In addition, as the LCD screen is changed to color and the resolution is increased, the brightness of the light displayed on the LCD screen increases, and users frequently use the light displayed on the LCD screen as a light source to illuminate the environment when searching for objects in a dark place. Doing.

However, as the brightness of light emitted from the backlight increases, the consumption of power charged in the battery increases, and thus, when the user frequently uses the light emitted from the backlight as a light source for illuminating the environment, the user calls the wireless communication device or the mobile phone. There was a problem that the capacity of the battery is insufficient when you want to use or other additional features.

Therefore, the present invention has been made to solve the above-mentioned problems, and the light emitting diode which emits light to the outer surface of the battery for supplying power to a mobile phone or a wireless communication device carried by many people recently is provided, such light emission The present invention provides a battery having a flash that a user can always carry by using power supplied to a diode directly from a battery.

The battery with a flash according to the present invention, as shown in Figure 1, the battery body 10 is provided with a power supply terminal 11, the light emitting diode 20 located on the upper portion of the battery body 10, It includes a circuit unit 30 for applying an appropriate current to the light emitting diode 20, and a switch 40 for controlling the power supply of the circuit unit 30.

The battery body 10 is a plastic housing surrounding the inside of the battery in order to protect the inside of the battery generally used in a mobile phone or a wireless communication device, a power terminal connected to the mobile phone or wireless communication device to supply power (11) is formed.

The power terminal 11 is a conventional battery power terminal located under the battery body 10 and formed on the front and rear of the battery body 10, and a charger is connected to a surface which is not in contact with a wireless communication device or a mobile phone. It is charged and is formed of a metal material through which a current can flow to supply power to the mobile phone through a surface contacting the mobile phone, and is formed of two metals having a positive electrode (+) terminal and a negative electrode (−) terminal.

In this case, in order to easily connect the LED 20 to be described later to the battery body 10, it is preferable to form the LED socket portion 12 provided on one surface of the battery body 10.

As shown in FIG. 3, the LED socket part 12 includes a connection part 36 for connecting the light emitting diodes 20 to the battery body 10, and the connection part 36 and the light emitting diodes 20. It consists of a rectangular parallelepiped housing 35 in which a storage space to be stored is formed.

The connection part 36 has a power connection port formed at one side of the housing 35 to be electrically connected to the power terminal 11 when the light emitting diode 20 is connected to the connection part 36.

The inner bottom of the housing 35 is provided with a reflector to improve light emission, and the upper portion of the housing is preferably formed of a structure that can be opened and closed to facilitate replacement of the light emitting diodes 20.

The light emitting diode 20 generates a small number of carriers (electrons or holes) using a p-n junction structure of a semiconductor and emits light by recombination thereof, and is also referred to as a light emitting diode (LED). In the present invention, it is preferable to use a high brightness LED.

The light emitting diode 20 may be configured as a light emitting diode in which two connection terminals protrude in one direction, as well as a light emitting diode in which connection terminals protrude in both directions.

The connecting line 31 is composed of a general wire through which current can flow from the positive terminal (+) to the negative terminal (-), and the resistor 33 has an appropriate resistance value according to the type of the light emitting diode 20. It is composed.

In general, a diode may flow in only one direction, and both sides of the diode exhibit a constant voltage characteristic when the current flows. As a result, there is no voltage drop proportional to the current, such as resistance, and voltage drop occurs regardless of the current flowing through the diode.

Therefore, since the light emitting diode also has the characteristics of a general diode, if a voltage higher than the rated operating voltage is applied to both ends of the light emitting diode, there is a risk that the light emitting diode is damaged while an overcurrent flows.

In order to solve this problem, a resistor is connected to the light emitting diode in series, and the resistance is used to cover a voltage exceeding the rated voltage of the light emitting diode, which is technically expressed as a transconductance that converts the voltage source into a current source. acts as a transconductance.

That is, when the power supply voltage across the light emitting diode and the series resistor changes, the voltage of the light emitting diode is constant. Therefore, only the voltage across the series resistor changes, so that the brightness of the light emitting diode can be adjusted with a current change proportional to the changed voltage. Will be.

For example, if a 5V voltage is connected to a light emitting diode rated at 3V, a voltage of 2V higher than the rated voltage of the diode is applied. Therefore, in order to handle an excess voltage of 2V at a current of 20mA, According to the formula, connect a resistor with a resistance of 2V / 20mA = 100Ω in series. This prevents the LED from being damaged by overvoltage.

The protection circuit module (PCM) circuit 34 allows the safety circuit to be driven during charging and discharging of the battery, thereby protecting the battery from overcharging and overdischarging, and preventing overcurrent from flowing into the mobile phone battery. This circuit protects the mobile phone and the human body from the battery and extends the battery life and maintains safety when using a wireless communication device or mobile phone.

The switch 40 is a general switch that controls the flow of current to emit light of the light emitting diodes 20. The switch 40 protrudes on one side of the battery body 10 so that a user can easily find the connection line 31. ) Is electrically connected.

In addition, it is preferable to wrap the outside of the switch 40 in a soft non-conductor such as rubber to prevent the user from being injured or electric shock when the switch is turned on or off.
