[00062] In the case of the illuminable connector of the second preferred embodiment, it may be used to provide an emergency charge to a discharged mobile device, at least to a level at which the mobile device can provide service.

Fourth Preferred Embodiment

[00063] With reference to figure 13 there is illustrated in electronic schematic form a circuit diagram for an illuminable connector and cable combination according to a fourth preferred embodiment. In this instance the components illustrated operate functionally as follows:

[00064] The Illuminable Connector (IC) is a multi-functional charging adaptor for smart devices such as smart phones, tablets or other portable devices. The functions include:

Provide a controllable source of illumination to locate the charging port of the smart device.

Function as a torch when disconnected from an external power source.

- Function as an emergency power bank providing up to 50% charge (ie 1500mAh) to a

typical smart device

[00065] The main electronic components are:

- Lithium Polymer (Li-Po) batteries with at least lSOOmAh

Battery charging circuit - providing SV output

- On/off switch (possibly with turn knob that adjusts the level of illumination)

LED (possibly surface mount types which are smaller)

Connector for input power (male) - USB 2.0/3.0

- Connectors for output power (male) - Micro B, Lightning or Type-C

[00066] In this instance the basic appearance of the IC may be similar to a charging cable but with slightly greater width and height. The width and height is then limited by the width and height (or thickness) of the Li-Po batteries. [00067] Components designated in figure 13 have the following specifications:

[00068] Material Considerations

[00069] In this embodiment the IC enclosure includes the following characteristics:

It is flexible.

The case can be used in typical indoor and outdoor environments.

The operating temperature is typical of Li-Po batteries being in the range (O - 50 °C).

It can take some amount of impact.

[00070] In a preferred form two versions can be constructed - a basic version that can provide up to a " half-charge" (1500mAh) - and an extended version that provides a full charge to a smart phone (3000mAh).

[00071] In a preferred form in order for the IC to be flexible, multiple small Li-Po batteries may be assembled length wise allowing the IC to bend in between the batteries.

[00072] In a preferred form the assembly is constructed as sealed so as to be water resistant.

Summary

[00073] A primary purpose of at least some embodiments of the invention is to assist in poor- absent light environments, to locate the charging port on portable devices, for example, though not limited to, mobile phones and tablets. It may be provided to users who, for example, use their mobile devices as an alarm clock, or sleep with the device within hand's reach. [00074] The connector may be provided with the options of full length battery assisted, short battery assisted adaptor options that fits in the palm of the hand, as well as a simple hard wired version without rechargeable battery. This latter version is ideally intended to be used as a primary power cable, generally remaining connected to a primary or mains power source, used in conjunction with short adapter (battery assisted) option.

[00075] Although the connector's primary purpose and function is to locate the charging port on portable devices in poor or absent light environments, it also has second and a third functions of providing a rechargeable torch and emergency mobile device charger. The rechargeable built-in battery cell will be constantly recharged while the connector is plugged in to a primary 240V input - 5V output, so that when disconnected from the primary power source the LED can act as a torch to, for example, assist in a midnight trip to the bathroom without disturbing a possible sleeping partner.

[00076] Thus the unique properties of the invention which distinguishes it from similar devices are;

The ability to control the LED by means of the momentary-contact switch and rechargeable battery cell,

- The data port connector ' s function of its primary purpose of USB data transfer and mobile device charging remain unimpaired,

The ability to function as a light source while disconnected from a primary power source. The ability to provide an emergency charge to a discharged mobile device.

[00077] Thus, with reference to Figure 12, this tri purpose device is intended to provide a controllable source of illumination to locate the charging or data port of a smartphone, tablet or other portable device. Its secondary purpose is its ability to become a torch once disconnected from its primary power source, enabled by its built-in battery cells. Its third purpose is its ability to provide an emergency charge to a completely discharged portable device. Adaptor versions will be limited to the number of battery cells and achievable charge percentage, but the full length cable versions may well be able to achieve a full charge to a completely discharged portable device, dependent on the number of battery cells built into the device.

[00078] The components depicted in Figure 12 are intended to give a clear understanding of the functions of the device. Components and circuitry may be altered accordingly to best suit end user market fit products. The device's intended functions will not be altered.
