Lighting arrangement using LEDs

Abstract

A lighting arrangement using LEDs that has an elongated translucent diffuser having a flat upper surface along the length of the diffuser. The transverse cross-section of the elongate translucent diffuser may have various shapes, all having substantially flat tops, including but not limited to quadrangular, rectangular, trapezoidal, and non-isosceles variations of these shapes. The elongated translucent diffuser is mounted on an elongated housing of substantially the same length to support the diffuser. The elongated housing may be solid or hollow and may contain the LEDs and circuit board, or the LEDs and circuit board may be contained within the elongated translucent diffuser. The LEDs are configured to transmit light through the diffuser so that the emitted light simulates light from a traditional neon tube.

Description

BACKGROUND OF THE INVENTION

The present invention relates generally to a sign, and more particularly to an illuminated sign incorporating an elongate diffuser or waveguide which provides a novel and attractive surface for emitting substantially uniform light.

Signs for storefronts and the like are well known throughout the art. For instance, signs for indicating whether a particular business is open, i.e., open signs, and the like are well known. Such signs have traditionally utilized neon for illumination of the sign. In such signs, a number of tubes are arranged to spell out the word or words desired such as, e.g., “OPEN”. Such tubes, traditionally round hollow glass, are filled with neon, argon, xenon, or other gases, and an electrical charge is applied to the gas by way of a pair of opposed electrodes at either end of the tube to thereby illuminate the gas and the tube. Such signs, however, suffer from a number of disadvantages. Neon tubes tend to be very brittle and susceptible to accidental breakage. During the manufacture of a neon sign the glass tubes, typically manufactured as straight linear hollow tubes, are heated and deformed into the illuminated elements of the sign, for example, to spell out the word “OPEN,” but must still retain an unobstructed hollow center with one or more ends for applying an electrical charge. The process is thus limited by the constraints of illuminating the tube with neon gas within, and the constraints imposed by the available traditional neon glass tubing which limits the design and appearance of the finished sign and requires a substantially complex fabrication process. Further, neon tubing is relatively expensive and thus replacement of the tubes is undesirable and cost prohibitive.

As such, it has become known to provide signs that simulate the appearance of neon tubing by using a series of light emitting members such as, for example, light emitting diodes (“LEDs”) arranged along the length of a housing and directed to emit substantially uniform light at a diffuser or waveguide to thereby illuminate the waveguide in a manner that simulates the appearance of neon. Such constructions are advantageous with respect to traditional neon signs in that the energy needs of these signs are quite small thereby reducing costs to the user. Further, as compared to traditional neon signs, the waveguides and housing may be produced from a relatively lighter weight and more malleable or moldable material other than glass, such as a plastic. However, such signs, despite the potential for modification of the waveguide shape made of more malleable material, continue to mimic the rounded surface of a glass tube. Diverging from the rounded light emitting surface of the neon glass tube can allow designs that are novel and thus stand out from traditional neon signs, thus becoming more noticeable and potentially more attractive to the human user. In addition, the waveguide can be designed to be more structurally sound, and can be fabricated without relying on bending or deforming glass in a secondary manufacturing step. Thus, it is desired to provide a sign that overcomes each of the foregoing disadvantages while maintaining the high quality illumination provided by the sign.

SUMMARY OF THE INVENTION

The present inventors have recognized that a significant feature of an illuminated sign is the structure and appearance of the light-emitting waveguide. Providing a waveguide that is practical, structurally and in terms of material cost, and novel or attractive, can positively affect the user's experience with the illuminated sign.

Specifically, the invention contemplates a simulated neon light including at least one elongated translucent diffuser or waveguide having an inner surface, an outer surface, and a hollow interior. The outer surface of the diffuser has a flat top portion extending substantially over the length of the elongated translucent diffuser. The light includes a housing that is configured for attachment to the translucent diffuser, and a series of light emitting diodes contained within the housing and aligned with a long axis of the elongated translucent diffuser. With this construction, the light emitting diodes when energized emit light that strikes the inner surface of the elongated translucent diffuser, such that a portion of the light is diffused and emitted by the flat portion of the outer surface. An electrical power source energizes the light emitting diodes. The simulated neon light thus has a novel look for attracting the user and enhancing their visual experience.

The housing may have an interior space and at least one open side, or the diffuser may be mounted to a support structure that is substantially solid. The diffuser may have a closed boundary extending substantially over the length of the diffuser and forming a hollow interior. The diffuser may be in the form of an assembly having a top wall portion and a securably attached bottom wall wherein the bottom wall may be a transparent or a translucent material. The diffuser may have a bottom wall that may be assembled so as to allow insertion of components, and constructed with minimal diffusive materials. Alternatively, the bottom wall may be opaque to light to allow light to only be emitted from the top wall portion of the diffuser when LEDs are mounted within the diffuser. The diffuser may have two substantially flat sides extending substantially over the length of the elongated translucent diffuser on either side of the flat top wall. The diffuser may have sides that are substantially orthogonal to the top wall or that are at an angle to the top wall. Mounting structure for attaching the LEDs may be integrated with the housing or with the diffuser.

Other aspects, features, and advantages of the invention will become apparent to those skilled in the art from the following detailed description and accompanying drawings. It should be understood, however, that the detailed description and specific examples, while indicating certain embodiments of the present invention, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof, and the invention includes all such modifications.

DETAILED DESCRIPTION

Referring now to the Figures, and initially to FIGS. 1-7, this invention relates to a lighting arrangement, such as an arrangement used to simulated neon light, which uses light emitting diodes (LED's) 27 as a light source to illuminate simulated neon lights, which are generally represented at 20.

A representative embodiment of the present invention is a sign 10, illustrated in FIG. 1 as an “OPEN” sign that is formed of a series of neon lights 20. However, it is understood that simulated neon lights 20 may be configured in a variety of shapes to display a variety of messages and designs of various colors and sizes as a sign or otherwise. It is also understood that the present invention may be used in any application, and that its use in the context of a simulated neon sign is but one illustrative example of the many applications in which the present invention may be used. In this representative embodiment, sign 10 includes a frame 16 configured for mounting the simulated neon lights 20. The simulated neon lights 20 in this embodiment are the quadrilateral border and letters ‘O’, ‘P’, ‘E’, and ‘N’ as shown in FIG. 1.

FIG. 2 shows a portion of one of the simulated neon lights 20, which includes a housing 26 and a waveguide diffuser 24 having a long axis 22, a width 42, and a length 28 wherein the diffuser 24 is securably attached to the housing 26.
