This invention relates generally to the field of light sources, and more specifically to providing self-adaptable light sources.
Light sources (e.g., flashlights, lanterns, light fixtures (both portable and fixed), and equivalents) have been known and used for many years, but such light sources have been limited in their usefulness.
One problem with prior art light sources is that they require mechanical movements by a user to focus a light beam (e.g., the user must move or twist something on the prior art light source to change it from producing a narrow beam to producing a wide beam or vice versa) or to change the light source from a lantern into a flashlight or vice versa. Another problem with the prior art light sources is that they do not indicate when their battery will run out. Prior art light sources are unintelligent and do not give the user valuable information about the battery of the light source or estimate the operational time remaining
The present invention provides methods to manufacture a self-adaptable light source and implementations of self-adaptable light sources. Embodiments of the invention can be implemented in numerous ways. Three aspects of the invention are described below.

Various embodiments of the invention with a higher sampling rate will give a more accurate calculation.
In one embodiment, the beam light 205, flood light 206, and lantern light 101 use LEDs 204 controlled by pulse-width modulation (PWM) or voltage control to adjust the light of the light source. In one embodiment, the digital focus 201 adjusts the light between multiple flood and beam states by blending the beam light 205 with the flood light 206 using pulse-width modulation (PWM) or voltage control, or an equivalent control.
In one embodiment, the cap sense body 202 uses capacitive sense technology to sense when the user is holding the self-adaptable light source. In one embodiment, the soft-switch 207 turns the self-adaptable light source on to the last setting. When the self-adaptable light source is on, a quick press of the soft-switch 207 disables/enables optional cap sense interface buttons (not shown), while a press and hold of the soft-switch 207 turns the self-adaptable light source off. In one embodiment, while one or more optional cap sense interface buttons are enabled, the user may use these buttons to toggle between beam light 205, flood light 206, and lantern light 101 modes, focus the light, and adjust light intensity. In one embodiment, if the user is holding the self-adaptable light source and has the beam light 205 and or flood light 206 on and then stops touching the cap sense body 202, the beam light 205 and or flood light 206 will fade off while the lantern light 101 fades in simultaneously.
The battery (e.g., a lithium polymer battery or lithium ion battery, or an equivalent battery) with charger circuit 306 is rechargeable and is used to power the LEDs, accelerometer(s), and the data processor 305.
In one embodiment, the 1D, 2D, 3D accelerometer(s) 304 detects user movements or gestures, and detects the position and orientation of the self-adaptable light source to control the light intensity, focus, and mode. In one embodiment, having at least two accelerometers 304 allows the data processor 305 to determine the preferences of the user without requiring the user to activate any button or switches, so such buttons or switches would not be necessary on the surface of the light source. In various embodiments, examples of commands dictated by movements and gestures may include, but are not limited to, the following:
The data processor 305 processes inputs from the cap sense body 202, cap sense interface buttons 203 and accelerometer(s) 304 and controls the LEDs 204 accordingly. The data processor 305 is also programmed to learn user preferences in one embodiment.
In one embodiment the self-adaptable light source has a head 102 and body 103 used to house all the electronics inside the product. In one embodiment there could be a connector (e.g., a USB Male A connector) used to plug in a USB cable to the self-adaptable light source. In one embodiment this connector outputs 5 volts DC. In one embodiment the connector could be a mini USB or round power plug used to connect 18 volts DC to 5 volts DC to charge the battery (e.g., lithium battery or equivalent chemical storage).
The substrate 300 (e.g., a printed circuit board, or equivalent) is used to mount electronic components. The one or more batteries 306 in one embodiment can be one or more 3.7 volt lithium polymer batteries (but in alternative embodiments the batteries can be any type of battery). The battery and charger circuit 306 can regulate the incoming voltage (e.g., 110 V, 18V, 5V, or other voltage) to charge the one or more batteries (e.g., one or more lithium batteries, or equivalent batteries).
In one embodiment the data processor 305 has digital input and output ports (not shown) to control the light source and optional buttons for user input.
In one embodiment, the one or more optional buttons (not shown) can be push buttons or capacitive sense touch buttons. In one embodiment a button can be used to toggle the operation and turn on and off the self-adaptable light source.
In one embodiment, the electricity is carried by one wire or trace, and the electrical ground is carried by two wires or traces. In another embodiment, simply two wires or trace (one wire or trace for the electricity and one wire or trace for ground) are used. In alternative embodiments more electrical wires or traces can be used. In one embodiment, there is a controller module that has an on-off switch and a charger port for charging a plurality of internal batteries.
The energy source in various embodiments can be one or more batteries, a photovoltaic electrical module, an electrical recharger, or some other equivalent electrical energy source with a capacity for supplying an appropriate amount of voltage and current. One embodiment of the invention uses one or more electrochemical batteries (e.g., lithium polymer batteries, lithium ion batteries, typically rated at 3.6 volts under normal conditions and 4.2 volts when fully charged, or other equivalent electrochemical batteries, either single charge or rechargeable, or other equivalent power sources). Most of the electrical power provided by such batteries will be used for supply power to operate electronics, and to operate the data processor.
Other embodiments of the invention are possible. For example, the self-adaptable light source could be composed of several laminations of various materials for different applications. Another embodiment of the invention could provide multiple adjustable connectors to accommodate different sizes and lengths of electronics, energy sources, and cords.
The exemplary embodiments described herein are for purposes of illustration and are not intended to be limiting. Therefore, those skilled in the art will recognize that other embodiments could be practiced without departing from the scope and spirit of the claims set forth below.
