Additionally, the backpack device is hand or machine-washable.
In one embodiment, the light up backpack device comprises a light component and a power pack component. The light component typically comprises a plurality of LEDs which are in communication with the power pack component. The power pack component comprises a microprocessor (or controller), at least one power source, a control switch, a transformer, a receiver, and at least one sensor, all for powering and controlling the LEDs. Further, at least one power source is typically a battery contained within a battery enclosure. In one embodiment, the battery is rechargeable. Then at least one battery provides the electricity needed to power the LEDs. Further, the power pack component, along with the battery, can be positioned inside the backpack device and communicates with the PCB (i.e., the plurality of LEDs) via wires or other connecting means.
In one embodiment, the power pack component comprises a transformer for voltage conversion. Specifically, the transformer converts the DC voltage from the battery to a usable DC voltage for the LEDs.
In one embodiment, the light component further includes a plurality of LEDs positioned on the exterior of the body component, wherein the LEDs provide illumination on the exterior surface in order to allow a user to be more easily seen in low-light conditions. Preferably, the device comprises at least one light emitting diode (LED), however, other fluorescent or incandescent lighting systems are contemplated. The plurality of LEDs can be situated around the perimeter or any location within the exterior surface of the backpack device in order to provide sufficient illumination for a user.
In one embodiment, the light component may be of a type comprising an LED, an incandescent, or a fluorescent, but is preferably a plurality of LEDs. In one embodiment, the plurality of LEDs are secured to a printed circuit board (PCB) via any suitable means as is known in the art. The PCB can be any suitable shape and size as is known in the art, with any number of LEDs attached. The PCB is then secured to the exterior surface of the backpack via adhesives, gluing, sewing, at least one nylon hook and loop strip, which enables the PCB to be temporarily installed and removed from the backpack device, as needed.
In one embodiment, the power pack component comprises a control switch which manually controls the plurality of LEDs. The control switch is located on the PCB of the LEDs and offers a means for a user to turn on or off the LEDs. In one embodiment, the power pack component is contained in a pocket attached to the interior of the front or back panel or is directly secured to the interior of the front or back panel.

In one embodiment, the power pack component comprises a light sensor. The plurality of LEDs communicate with the light sensor to turn off the LEDs when ambient light is detected. It shall be noted that the term ambient light is being used to describe light that is provided by the outside environment and may be artificial or naturally produced. Further, the light sensor will only turn off the LEDs after a predetermined period of time of ambient light is detected. For example, the predetermined amount of time may be 30 seconds of ambient light that is required before the light sensor turns off the LEDs. Furthermore, after a predetermined amount of time has elapsed where there is no more ambient light, the light sensor can turn the LEDs back on provided that the control switch is turned to the “ON” position. Thus, the light sensor ensures that the powering means (i.e., battery) are used efficiently.
In one embodiment, the power pack component comprises a motion sensor that is an impact sensor for detecting impact motion, such as occurs when walking. In a preferred embodiment, the controller determines a rate of motion detected by the motion sensor and sets a corresponding activation pattern, wherein the controller deactivates the LEDs after a predetermined period of time of detecting substantially no motion. Upon detection, the motion sensor transmits a signal to the microprocessor to activate the LEDs. The motion sensor also detects when the user stops moving, thereby deactivating the LEDs. The motion sensor may rely on any means, including microwave energy, ultrasonic waves, or radio frequency signals, to detect the motion of a user with the backpack device, however, infrared means are preferred.
In the preferred embodiment, the motion sensor is a passive infrared radiation detector (PIR). The motion sensor is sensitive to changes in radiation from within a close range. The user within the range emits infrared radiation of sufficient magnitude to trigger the motion sensor to provide an output signal. It is preferable, that the range of the motion sensor is narrowly focused to avoid detecting extraneous movements. Too large of a range will unnecessarily activate the lighting assembly, while too small of a coverage area will not activate the lighting assembly when required.
In one embodiment, the controller detects motion of the backpack via the motion sensor, the controller activates the LEDs with a corresponding rate of activation. As the rate of motion of the user will vary as the user increases and decreases motion, the rate of activation of the LEDs will vary. A variable illumination of the LEDS will increase the likelihood of the user and backpack device being noticed by other people.
In one embodiment, highly reflective material may surround opposing sides of the LEDs. It shall be noted that the use and amount of highly reflective material is important in that the more, the better.
In one embodiment, a schematic diagram of the light component and power pack component of the backpack device is shown. The light component includes at least one LED that employs at least three different color diodes in one casing; traditionally, these are red (R), green (G), and blue (B). The different colored diodes can be combined in different proportions to produce thousands of resultant colors when viewed by the human eye. In some embodiments, the LED includes fiber optic filaments attached thereto to allow the light illuminated from the LED to travel through the filament and glow at the other end.
The power pack component comprises a microprocessor, and a power supply in addition to at least one LED. In certain embodiments, at least one LED is formed into one or more arrays of LEDs, wherein each array that emits the same color have their cathode and anodes electrically tied together to form a channel. The channel is controlled by the microprocessor independently of the other channels. It is possible that some arrays may have a higher or lower total number of LEDs than others. It is also possible to have an array with only one LED that forms a channel.
Preferably, the power pack component includes one microprocessor to control the illumination and color of the LEDs, however, some embodiments may have multiple microprocessors controlling multiple sets of LEDs and their respective arrays. In operation, the user selects the desired resultant light color (i.e., white, purple, green) for the desired LED via a control switch. Preferably, the control switch is a sliding switch or a touch wheel switch, however, as readily recognized by those of ordinary skill in the art, a variety of control switches are appropriate, and these alterations and modifications are likewise contemplated. In addition, the control switch is configured to manually activate and deactivate the light component. The control switch is positioned on the power pack component and placed on a bottom surface of the interior volume of the backpack device, however, it is likewise contemplated that other suitable locations of the control switch are likewise contemplated, such as directly on a PCB. After the user selects the desired resultant color, the control switch relays the desired resultant color to the microprocessor.
The microprocessor controls the relative intensity level of each LED to achieve the desired resultant color. The intensity level of the LED is controlled using a pulse-width modulation (PWM) algorithm of a fixed current source provided by the power supply, preferably a battery. The microprocessor is able to control the different colored diodes within the LED by varying and modulating the current and relative intensity level to one another that flows through the different colored diodes that are encased within the LED. In the preferred embodiment, this is done by the PWM algorithm within the microprocessor, which adjusts the PWM for each LED to achieve the desired resultant color.
The PWM algorithm allows linear control of the intensity level of the different colored diodes in the LEDs; that is, the intensity level of the different colored diodes in the LED is directly proportional to the width of the pulse. The PWM algorithm uses pre-stored calibration data to determine the PWM that should be applied to achieve the desired resultant color. By varying the PWM of the different colored diodes of the LED, it is possible to generate thousands of different resultant colors. Although a microprocessor using a PWM algorithm is disclosed, this does not imply that there are no other means of accomplishing voltage and current control. These means are readily apparent to those of ordinary skill within this art and are all deemed within the spirit and scope of the present invention.
