Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to lighting devices, and more specifically, to a lighting device positioned in a bag to illuminate interior space of the bag to facilitate search for items contained therein.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.
[0003] Individuals frequently employ any number of portable fashion accessories to transport their personal effects. For example, many women carry a purse, a handbag, and, modern trends have seen a growth in the number of similar accessories for men beyond the traditional briefcases and attaches. A variety of items such as keys, pen, and makeup items may be stored and contained within handbags.
[0004] A common problem in the use of handbags is finding a specific item in the handbag, this is particularly tiresome in conditions of poor light, as it is necessary to identify an item only by its shape, especially when there are items of similar shape inside the handbag. It is difficult and time consuming to dig through handbag to locate an item stored within especially in night, or in dark places. Many people unload their handbag completely to find single item, but this is not always practical, convenient, or even possible. Sometime an external light source such as flashlight of phone or torch is used, but this requires one hand to hold the light, thereby leaving only one hand to search in the handbag. And, when the mobile phone or torch is itself in the handbag, the user must first locate mobile phone or torch itself, thereby further complicating the issue. Oftentimes, in frustration, the user ends up just feeling around in the dark for the item until it is located by touch.
[0005] Therefore, there is a need in the art to develop a lighting device that makes it relatively easy to locate items such as keys, money, and other personal accessories enclosed within a bag, thereby eliminating the need to activate a torch or smartphone light into the bag and dig around with other hand.

[0036] In an embodiment, the device 100 can be coupled to any purse, handbag, wallet, backpack, briefcase, and suitcase easily with a fastening means provided on the housing, or it can be positioned on base surface of any of a compartment of the bag.
[0037] In an exemplary embodiment, the housing 102 can be designed in such a way that all the components are accommodated inside, and no wire is visible, also, enables the user to use the device 100 easily without entangling into wire. By way of example, the housing 102 can be like a small box of any shape square, rectangular, circle, and the likes, and can be made of any material like metal, plastic, and etc.
[0038] In an exemplary embodiment, the housing 102 can accommodate all the wires of internal communication in between the lighting elements 104, the power source 106, the sensors 108, the control unit 110, and a LDR 112 to obscure these elements from view when the bag is open.
[0039] In an embodiment, the lighting element 104 can include any or a combination of like but not limited to LED strip, bulb, tube, and electric luminescent wire. For example, a strip of flexible material provided with a plurality of LEDs, all supplied through a single external connection can be coupled to the housing 102. Also, lighting elements 104 can vary in number and type, including colored lights, such as blue and pink.
[0040] In an exemplary embodiment, the lighting elements 104 can be secured to housing 102 by mechanical sealing (e.g., crimping), affixing, magnets , and fastening means such as clip formed of a plastic, metal or other material, thereby facilitating its removable mounting or attachment to any of a variety of portions of the interior of the bag. Also, the lighting elements 104 can be removed from the housing easily, to enable the user to charge electronic device with in build power source 106 provided in the housing 102.
[0041] In an embodiment, the power source 106 can be electrically coupled to the lighting elements 104 to provide electric power to illuminate each of the lighting elements 104. The power source 106 can include any or a combinations of, but not limited to, batteries, inverters, and power lines. In another embodiment, the power source 106 can include a power bank (i.e. wireless battery) having lithium-ion batteries most preferably, to store energy. It may be readily apparent to one in the art that the power source 106 can be selected as appropriate to provide sufficient power, as per the electrical requirements of the lighting elements 104.
[0042] In an embodiment, the power source 106 can be a rechargeable power source, which can be configured to receive external power (e.g., to recharge) from an external power source, such as a wall outlet, or any other suitable source of external power. Electronic communication may be established between the power source and the external power source by a cable. In an exemplary embodiment, the user can attach the cable with the power source 106 and the source of external power at the time of charging the device 100, by removing the device 100 from the bag.
[0043] In an exemplary embodiment, the cable can be of standard type (USB, mini-USB, micro-USB) or of proprietary type and dedicated to devices of a given manufacturer. And, the cable can be provided with a quick release connection to be uncoupled from the external power source.
[0044] In an embodiment, the power source 106 can be used to supply electric power to an electronic device, such as, a personal data assistant (“PDA”), a cellular telephone, mobile phone, smart watches, earbuds, earphones, and another electronic devices. The power source 106 can include a means for providing electronic communication between the power source 106 and the electronic device.
[0045] In an exemplary embodiment, the power source 106 (i.e. wireless power bank) can provide wireless charging to the device 100, which works on electromagnetic induction, where coils of wire can be provided in the base station (the charging plate), which can create magnetic field as current passes through, and can induce an electrical current in an adjacent coil of wire without actually touching it, and when the wire is part of a battery charging circuit, wireless charging can be provided easily. Wireless power bank 106 can be used with the lighting device 104 easily.
[0046] In an embodiment, the sensors 108 can be configured within the housing 102 to detect the entity in a pre-defined area near the bag. The sensors 108 can include but not limited to proximity sensor, motion sensor, image capturing unit, and infrared sensor. During use, the sensors 108 can be activated based on the presence of the user, such activation can occur when the user reaches into the bag, or when the user approaches the bag. The activation of the sensors 108 can send a first set of signals to the control unit 110, to activate the lighting elements 104 to illuminate interior of the bag. Also, the lighting elements 104 can be deactivated upon removal of the item causing activation of the sensors 108, such as when the user removes their hand from the interior of the bag.
[0047] In an embodiment, upon detection of an entity, at least one of the sensor 108 can generate and transmit a first set of signals to the control unit 110. In an exemplary embodiment, the sensors 108 can be coupled within the housing or near the zipper, clasp mechanism, button, snap, and Velcro also to detect presence of the entity.
[0048] In an embodiment, the control unit 110 can include one or more processors. The one or more processors may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processors may be configured to fetch and execute computer-readable instructions stored in a memory operatively coupled to the one or more processors. The memory may include any non-transitory storage device including, for example, volatile) memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.
[0049] In an embodiment, the control unit 110 can be communicatively coupled to the sensors 108 and the power source 106. The control unit 110 can include one or more processors associated with a memory, the memory storing instructions executable by the one or more processors. The control unit 110 can be configured to analyse the received first set of signals to be assured regarding the presence of the entity in the proximity of the bag and correspondingly actuate a LDR 112. The LDR 112 can detect daylight, natural light, or light inside the bag and generate a second set of signals which can be transmitted to the control unit. The second set of signals pertains value of intensity of the light in the interior of the bag already.
[0050] In an embodiment, upon receiving the value of intensity from the LDR 112, the control unit 110 can activate the lighting elements 104 with a pre-defined intensity. In an exemplary embodiment, the pre-defined intensity can use different level such as high, mid, and low. When the light in the interior of the bag is found normal, the lighting elements 104 can be illuminated at a low level. Similarly, when no light is found in the interior of the bag the lighting elements 104 can be illuminated at a high level.
[0051] In an embodiment, the light dependent resistor (photo resistor) 112 can be used to detect light in the interior of the bag, when the light falls on the LDR 112, then the resistance changes, and accordingly the LDR 12 can transmit signals to the control unit 110. For example, when the LDR 112 is in darkness, then it can commands the control unit to activate the lighting elements 104 with high level intensity, and when brightness is found by the LDR 112 in the interior of the bags, it can command the control unit 110 not to activate the lighting elements 104 or only activate the lighting elements 104 with low level intensity, that assists in saving power.
[0052] In an exemplary embodiment, an on/off switch (not shown) can be positioned at or near an opening of the bag, such as zipper, snap, Velcro, button, and the likes, which can be used to activate the lighting elements 104 manually. For example, a user, such as a contractor, may need to leave their bag open throughout the day while working, and the lighting elements 104 are turned on whole day, even the light is not necessarily needed. In this manner, having the on/off switch (or other power interrupter) would be useful for conserving battery power and the overall useful life of the device 100. When the bag is opened by the user, the user can turn ON the switch to activate the lighting elements 104 to illuminate interior of the bag, and the user can turn off the switch to deactivate the lighting elements 104 when the item is found or needs to close the bag.
[0053] FIG. 2 illustrates a circuit diagram of a lighting device in accordance with an embodiment of the present disclosure.
[0054] As illustrated, a circuit 200 is disclosed, the circuit 200 can include a light dependent resistor 112, power source (shown as battery), transistor Q1, lighting elements 104, relay (shown as on/off switch), and resistors R1 and R2. In an embodiment, the transistor Q1 can be configured with to control flow of current in the circuit to activate and deactivate the lighting elements 104 accordingly. In an exemplary embodiment, BC547 can be used in the circuit of the proposed invention which can perform two operations forward bias and reverse bias to control supply of electric power in the circuit. In an embodiment, when the bag is opened by the user, it can be detected by at least one of the sensor 108, correspondingly the control unit 110 can actuate the light dependent resistor 112 to detect light falling on it.
[0055] In an exemplary embodiment, when the bag is opened in daylight, the sensor 108 can detect presence of a user and commands the control unit 110 in the form of first set of signals, the control unit 110 can analyse the first set of signals, and can actuate the light dependent resistor, when the user is found in the proximity of the bag. Upon actuation, the light dependent resistor 112 can detect light falling on it, and if it is found less compared to the resistance of circuit, the light dependent resistor 112 can commands the control unit 110 to activate the lighting elements 104 with low intensity, or commands to subsist deactivated, where the command can be transmitted in the form of second set of signals. The control unit 110 can extract level of intensity from the second set of signals, and accordingly control intensity of lighting elements 104. Similarly, when the bag is opened in night time, and the light dependent resistor 112 can be actuated by the control unit 110, the resistance can be found high, thus, the light dependent resistor 112 can commands the control unit 110 to activate the lighting elements 104 with high intensity.
