Description

FIELD

The field of the present disclosure generally relates to work lights. More particularly, the field of the invention relates to an apparatus and a method for a modular lighting system that may be advantageously configured into multiple lighting sources.

BACKGROUND

Automotive technicians are often responsible for performing maintenance on vehicles, as well as diagnosing problems. For example, an automotive technician may perform engine oil changes and tune-ups to keep vehicles in good working condition. Because technicians usually work in tight spaces that may also be dark, having proper lighting is crucial. The issue of dark spaces is exacerbated by the many shadows that are cast in an engine compartment due to the volume of automotive components located in the compartment. Effective lighting is important for safety of the technician, as well as enabling the technician to accurately see and better perform work on the vehicle.

A drawback to conventional lighting systems is that not all required surfaces can be desirably lit at the same time with a single lighting source. As a result, the technician is forced to use larger and brighter lights or light sticks to insert into the engine compartment. Unfortunately, the larger lights produce significant amounts of heat, especially if a particular troubleshooting area requires many hours of attention. Moreover, the larger lights often fail to illuminate the desired area. Singular lighting sources are also cumbersome in that they must be moved multiple times during a single project so as to provide the desired lighting, undesirably increasing the time required to finish a project. Utilization of multiple lighting sources may also be cumbersome due to the associated costs, and the increased clutter in the workspace. Finally, multiple lighting sources often require multiple power sources and corresponding runs of power wire, which may present a hazard in inherently dangerous working areas.

What is needed, therefore, is a modular lighting system that provides light from a plurality of sources that is capable of being manipulated in and around work areas without introducing any of the safety issues associated with conventional solutions.

In one embodiment, the lighting sources 420 may comprise one or more light emitting diodes (LEDs) disposed in any number of different configurations. However, because the light produced by an individual LED is conventionally directional and focused, it is preferable to use a plurality of LEDs in the embodiments as discussed herein. Using arrays or groups of LEDs, as well as lenses or optics, a LED lighting product can provide light over a larger area, for either ambient or task functions. In general, LEDs are driven by constant current (350 mA, 700 mA or 1A) drivers or constant voltage (10V, 12V or 24V) drivers. It is contemplated that constant current drivers may fix the current of and vary the voltage of embodiments as discussed herein, depending on the load of the LED. As most constant voltage drivers require a fixed voltage, the LED loads may be added in parallel across the output of their respective driver(s) until maximum or desired output currents are reached.

In one exemplary embodiment, the LEDs may take the form of LED strips, although the individual LEDs may take any form, size or color. As will be appreciated, the LEDs may be of the single-die, medium power variety, or may be high-power, as well as any combination thereof.

In yet another embodiment, the LED strips may be digital, such that the color of each individual LED may be changed so as to enable creating various screens and effects. As those skilled in the art will appreciate, any number of LEDs may be implemented on a particular LED strip. For example, LED strips typically comprise 30, 42, 60 or 120 LEDs per meter. It will be further appreciated that utilizing relatively more LEDs generates a higher intensity of smooth light.

In one embodiment, the lighting source 420 may comprise one or more fiber optic strips. In one embodiment, the lighting source 420 may include one or more side illumination fiber optic light guides. In one embodiment, the lighting source 420 may be a combination of various types of lighting sources. Fiber optic light guides may transmit light through glass optical fibers. In one embodiment, the lighting source 420 may comprise one or more flexible side glow fiber optic solid cores, which are well suited for linear fiber optic lighting applications such as neon replacement, cove lighting, accent lighting, as well as lighting a work area.
