The present invention lies in the field of lighting devices and fixtures used to illuminate a subject and/or an area. In particular, the present invention relates to a new form of LED lighting material that can be used for any general lighting purpose, but has a particular use in photography and film production settings.
Due to certain characteristics and qualities of lighting devices (and fixtures) used in the film and photographic industries for illuminating a subject and/or an area, these lighting devices impose several limitations that can hinder and impede the production process. For example, the lighting devices require a lot of power and generate a lot of heat, making it difficult to use the lighting devices for a prolonged period without causing discomfort and requiring fanning or air conditioning. Moreover, the power required to supply the lighting devices is a significant cost. In addition, the lighting devices are relatively large. Therefore, a significant amount of designated space is required for their use. Transportation of the lighting devices from one place to another is not easily accomplished. Accordingly, this limits the movement and angles of the camera, thereby limiting the end product as a result. Also, with respect to filming, the time needed to switch a lighting element of the device from a daylight source to a tungsten source adds time to the filming process and slows its production.
Accordingly, a need exists to overcome the problems with the prior art lighting systems, designs and processes as discussed above.
The invention provides a lighting material, comprised of light emitting diodes (LED), that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that provide such features with an ability to illuminate a subject and/or area with greater flexibility and that would eliminate many of the limitations of prior art lighting devices. By using LEDs, a significant amount of illumination is still possible despite using less power, generating less heat, and using less space.
By way of background, in the photography and film production industries, there are devices referred to as scrims or diffusers that are used to control or adjust the quality of the light on a set. In the still and motion picture lighting industry, these devices are typically comprised of frames with diffusion cloths attached to the inside of the frame. These devices usually are found in 2′×2′, 4′×4′, and 8′×8′ feet dimensions.
The lighting material described herein is comprised of a plurality of flexible LED light strips that are attached, permanently or removably, to a flexible substrate or material to form a flexible material of light. For example, the LED light strips may be affixed to a fabric material to form a sort of cloth “rag” that can be wrapped around, attached to, or draped on many different surfaces. Because both the fabric and the LED light strips are flexible, the finished material may be wrapped around a ball and the entire ball then outwardly radiates light in a spherical shape. Moreover, as described in further detail below, this lighting material can be put into standard frames or, may be put into the frame assemblies contemplated herein, to produce a device that functions much like the scrims or diffusers used in the photography and film production industries.
Additionally, due to the modular nature of the lighting materials described herein, a number of these cloths can be placed adjacent to one another and fastened together to create a larger or distinctly shaped lighting unit. Each cloth can also be mounted directly onto a wall, like a painting, to produce light with use of a very small space. Again, the inherent flexibility of the LED light strips and the underlying substrate or material allows the finished lighting material to be easily adapted to different surfaces in a variety of ways to dynamically create a lighting element or device that is easily portable and adjustable such that it may be configured for use in many different environments and circumstances.
With the foregoing and other objects in view, there is provided, in accordance with the present invention, a lighting material, comprising a flexible substrate comprising at least one fastener shaped to removably attach the flexible substrate to a surface of the environment, at least one flexible LED light strip having LED elements and being affixed to the flexible substrate, and an electric ballast electrically connected to the at least one flexible LED light strip and, when operated, supplying power to the at least one flexible LED light strip to light at least some of the LED elements.
In accordance with another mode of the invention, a plurality of the flexible LED light strips are affixed to the flexible substrate adjacent to one another.
In accordance with a further mode of the invention, the at least one flexible LED light strip is removably affixed to the flexible substrate.
In accordance with an added mode of the invention, the flexible substrate is a first flexible substrate, and further comprising a second flexible substrate having at least one flexible LED light strip affixed thereto, the second flexible substrate further comprising at least one second fastener shaped to removably attach the second flexible substrate to the first flexible substrate.
In accordance with an additional mode of the invention, the electric ballast has an LED controller that, when operated by a user, controls characteristics of at least one of the LED elements and the flexible LED light strip.
In accordance with yet another mode of the invention, the at least one fastener removably attaches the flexible substrate to a frame assembly.
In accordance with a further mode of the invention, there is also provided a lighting device comprising the lighting material and a collapsible frame assembly to which the at least one fastener removably attaches the flexible substrate.
In accordance with another mode of the invention, the collapsible frame assembly has components adjustable to form different frame dimensions.
In accordance with an added mode of the invention, the LED elements provide light sufficient to illuminate an area of a photographic setting.
In accordance with an additional mode of the invention, the LED elements provide light sufficient to illuminate an area of a film production setting.
In accordance with yet another mode of the invention, the flexible substrate is a first flexible substrate and further comprising a second flexible substrate having at least one flexible LED light strip affixed thereto, the second flexible substrate further comprising at least one second fastener shaped to removably attach the second flexible substrate to the collapsible frame assembly.
With the objects of the invention in view, there is also provided a lighting kit, comprising at least one flexible substrate comprising at least one fastener, at least one flexible LED light strip having LED elements, fasteners shaped to removably affix the at least one flexible LED light strip to the at least one flexible substrate, a collapsible frame assembly to which the at least one fastener removably fastens the at least one flexible substrate, the collapsible frame assembly being adjustable to form different frame dimensions, and an electric ballast electrically connected to the at least one flexible LED light strip and, when operated, supplying power to the at least one flexible LED light strip to light at least some of the LED elements.
In accordance with another mode of the invention, the at least one flexible LED light strip of the lighting kit is a plurality of flexible LED light strips and the fasteners are shaped to removably affix the plurality of flexible LED light strips to the at least one flexible substrate.
In accordance with a further mode of the invention, the at least one flexible substrate of the lighting kit is a plurality of flexible substrates and the fasteners are shaped to removably affix the plurality of flexible LED light strips to the plurality of flexible substrates interchangeably.

Referring now to the figures of the drawings in detail and first, particularly to
The LED light strips 10 may be affixed to any flexible, but durable, substrate or material of any type, size, and/or shape that is suitable for its application. Thus, the finished lighting material 1 is easily portable and flexible and, therefore, can easily be applied to and accommodate the shape of nearly any object or fixture (e.g., a window, wall, door, car, frame, column or pole, or sphere) for illuminating a desired subject or space. By way of illustration,
The LED light strips may be detachably or permanently affixed to the underlying material or substrate of the lighting material in a variety of different ways. For example, the LED light strips can be sewn to the substrate or permanently attached to the substrate using a strong adhesive. In the exemplary embodiment shown in
In
Advantageously, a theoretically unlimited number of these flexible LED lighting materials can be temporarily or permanently fastened side-by-side to each other to expand the dimension and scope of the lighting material in an unlimited manner. Any suitable fastener or other connecting measures can be used to interconnect the lighting materials to each other. For example, as shown in the exemplary embodiment of
Furthermore, a myriad of ways of temporarily attaching the individual lighting materials to the surface of an object, fixture, and/or frame are contemplated herein and will ultimately depend on the type of surface to which the lighting material is being attached. For example, in the event of a relatively flat surface, suction cups or snaps can be used to attach the lighting material thereto. In the exemplary embodiment illustrated in
In another example, best shown in
To specifically adapt the flexible LED lighting material to the film and photographic industries, the lighting material may be provided as part of an assembly kit (or product) for constructing a scrim or diffuser as used in the art. Along with one or more of the lighting materials, this inventive kit also contains one or more collapsible frame assemblies that can be built to different dimensions ranging from, for example, 1-feet by 2-feet, 2-feet by 2-feet, 2-feet by 4-feet, to 4-feet by 4-feet. Each collapsible frame assembly may be specifically designed to be used with the lighting material (e.g., the frame's dimensions or any fastening measures that correspond or mate to the fasteners of the lighting material). To construct the scrim or diffuser, the collapsed frame is built to the desired size and one or more of the lighting materials is affixed to the frame using, for example, snaps, any of the attachment methods described above (and shown in
Once a frame structure is built from the collapsible frame assembly 350, the LED lighting material may be temporarily attached to the frame structure using any suitable type of attachment mechanism, including the various types described above. For example, in the exemplary embodiment shown in
As mentioned above, to supply electrical power to the one or more LED light strips of the lighting material, a ballast system 20 is provided. As depicted in
The electric ballast 35 not only supplies electrical power to the lighting material, but can also be configured to control a variety of functions of the lighting material. For example, the electric ballast 35 may comprise control circuitry that provides the ability to control and adjust the color temperature and light intensity of the LED elements of the LED light strips. In another example, the electric ballast 35 may be able to intelligently determine when a malfunction (e.g., a burnout) occurs in one or more of the LED elements or LED light strips and automatically cease the flow of electrical power to that particular LED element and/or LED light strip and/or automatically adjust the direction of flow and/or the amount of electrical power that is being supplied to the working LED elements and/or LED light strips to protect the working LED elements and/or LED light strips from being damaged due to the malfunction. In addition, control circuitry may be incorporated into the electric ballast 35 to allow a user to manually operate one or more switches to adjust certain parameters or characteristics of the LED elements by using a control device that is hardwired to the lighting material 1 with a control cable (not shown). Alternatively, wireless functions may be incorporated into the electric ballast 35 that would allow the user to remotely transmit control signals (e.g., via Wi-Fi or DMX) from a remote console (not shown).
