Abstract

The embodiments described and claimed herein relate to insect traps (10; 110; 210). One particular embodiment of the insect trap comprises a housing (12; 112; 212) which holds a insect attracting light source (60a; 60b; 160a; 160b), an insect immobilizing device (190), and a visible spectrum light source (80a; 80b; 180a; 180b). The housing at least partially conceals the insect attracting light source, the insect immobilizing device, and the visible spectrum light source from view and includes a channel (14a; 14b; 114a; 114b; 214a; 214b) into which insects can enter the housing and approach the insect immobilizing device and through which a graduated pattern of insect attracting light can be projected into an area desired to be free from insects. The light pattern emitted from the insect trap includes a diffused light component (77a; 77b) that is reflected off of a reflective surface (26a; 26b; 126a; 126b; 226a; 226b) and an intense light component (78a; 78b) that is transmitted through a light conduit (70a; 70b; 270a; 270b). The light conduit captures light from the insect attracting light source from a first end that is in close proximity to the insect attracting light source. A second end of the light conduit is disposed near the opening of the channel and is oriented in such a manner so as to transmit the insect attracting light source into the direction of the area desired to be free from insects.

Description

- 1 AN INSECT TRAP TECHNICAL FIELD [0001] The present invention relates to an insect trap which is disguised as an ordinary light fixture or wall sconce. Such an insect trap is of particular application in eating establishments. BACKGROUND OF THE INVENTION [0002] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field. [0003] It is well known in the art to use ultraviolet ("UV") light as a means for luring insects into a trap. UV light is one form of electromagnetic radiation that has a wavelength in the approximate range of between 100 and 400 nanometers ("nm"). Although the human eye is unable to detect ultraviolet light, some animals, including many insects such as bees and flies can see UV light. UV light is subdivided into three bandwidths: UV-A, UV-B, and UV-C. UV-C is sometimes referred to as extreme ultraviolet and is characterized by wavelengths between 100 and 280 nm. UV-B is sometimes referred to as far ultraviolet and has a wavelength between 280 and 315 nm. UV-A, which is particularly relevant to the present invention, is sometimes referred to as near ultraviolet and has a wavelength between 315 and 400 nm. Light which is often referred to as a "dark light," "black light," or "black light blue" all generate UV-A light. [0004] There are several theories as to why insects are attracted to UV-A light. In their natural state, insects would be foraging and / or searching for food resources in vegetation which is in shadow and darkness. The way out of this environment is to seek light, and in particular UV light, as it is an element of sunlight. When insects fly from the interior of vegetation towards open space, they seek a bright light gap, or light intensity graduations. Also, some flowers, fungi, and liquids reflect UV-A light. Insects are believed to associate UV-A light with food sites, mating opportunities, and potential egg laying sites. UV-A is therefore believed to be a key component of insect vision.

-2 [0005] It has been observed that a number of factors positively affect the efficacy of light emitting insect traps (i.e., the rate of catch and type of species), including bulb brightness, the size of the UV emitting area, bulb orientation, trap location, flicker frequency, and wavelength. Although it is generally true that traps which incorporate brighter bulbs tend to have a greater catch rate, manufacturers must weigh a number of factors when selecting bulb brightness, such as regulatory limits on radiation exposure. The trap location has relevance since a competing UV source, such as outside light, can minimize the catch should the unit be placed by a window. Also, the insect trap ideally should be placed where insects typically go; for example, the insect trap preferably should be spaced from the ceiling. It has also been observed that insect attraction increases with increasing light intensity and when there is some background luminosity. In other words, a greater insect response can be had when a UV light pattern is emitted which includes zones of high and low intensity light. [0006] It has further been observed that UV light sources which peak in the range of 345 to 375nm, and more preferably at a wavelength of slightly less than 360 nm, provide optimum insect response. The selection of this optimal wavelength is based upon empirical research on the peak response of various insects. For example, house flies have a UV peak response at 340-350 nm. Honey bees have a UV peak response at 336 nm. Fruit Flies have a UV peak response at 345 and 375 nm. Although research continues in the spectral response of different species of insect, it has been extrapolated from the given examples that Dipterans have similar optical resolution capabilities and that UV sources that emit sub 360 nm engenders a greater response in such creatures. [0007] Finally, it has been observed that an increased catch rate may be achieved when UV-A light is directed towards the area desired to be free from insects, rather than at the wall like some prior art devices. It is believed that directing the UV-A light outward, as opposed to directing the UV-A light against the mounting wall surface, better simulates an available exit from dense vegetation. When insects fly from the interior of vegetation towards open space, they do not see a big blanket of UV light, and instead will see light within gaps between leaves that vary in size. [0008] It has been found that prior art devices that utilize UV-A light as a lure have failed to include many of these efficacy increasing features while at the same time providing a device which is well accepted by consumers. Insect traps that utilize UV-A light are often used at eating establishments, where patrons do not want to see an exposed light bulb, much less an insect trap, the thought of which can be unappetizing.

-3 PRESENT INVENTION [0009] It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative. [0010] According to the present invention there is provided an apparatus for trapping insects and which is configured for installation on a wall surface comprising: at least one insect attracting light source that emits insect attracting light; at least one insect immobilizing device which is configured to immobilize insects; a housing holding the insect attracting light source and the insect immobilizing device; a cover which at least partially conceals the insect attracting light source and insect immobilizing device from view and prevents the insect attracting light source from directly emitting light in a direction normal to the wall surface and within approximately 30-40 degrees on either side of normal ; and an opening projecting outwardly forward through which insects may enter the apparatus; at least one light conduit in the form of a light transmitting plate like structure or fibre optic like device comprising a first end in close proximity to the insect attracting light source to capture insect attracting light that is emitted therefrom and which transmits the light along itslength to a second end, disposed near the opening, from where it is emitted to project intense concentrated patterns of insect attracting light outwardly forward from the apparatus, and at least one light channel which reflects light outwardly from the light trap and is configured such that the insect attracting light leaves the at least one light channel in a diffused pattern and wherein the diffused and concentrated patterns of light merge to form a light pattern having intensity graduations. [0011] Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to". [0012] One exemplary embodiment of a light trap utilizes two (UV-A) lamps that are at least partially hidden within the trap, but are configured to project UV light out of two light channels which face forward, away from the wall surface to which the trap is mounted. The two light -4 channels are on the left and right sides of the unit, and can include structures to prevent any display or pattern on the wall with regard to UV light. [0013] The light traps may also include two visible light sources, which can be two lamps which will deliver task lighting or an LED output which will deliver a more accent lighting, the application dictating which approach to adopt. In one instance, the visible light sources can be oriented to project light on to the wall. The visible light sources do not emit any UV component and as such do not significantly contribute to the light attraction mechanism. In such a manner, the visible light sources add to the overall assembly in its masquerade as a wall wash illumine. By combining the visible and invisible, insect attracting, light in one device, yet keeping each discreet, the unit can be perceived first and foremost as a wall wash light, thereby permitting the unit to be deployed in sensitive areas. [0014] Light pipes can be fitted within the light channels to display a vertically intense UV line within the UV radiation loom to manipulate the UV signature of the light trap. Insects sighting the UV irradiation would approach and be attracted towards the source and enter the unit where the intensity of UV is greater. Inside the unit, behind a front panel is a replaceable control board (adhesive covered board) on to which an insect could be entrapped. [0015] Other embodiments, which include some combination of the features discussed above and below and other features which are known in the art, are contemplated as falling within the claims even if such embodiments are not specifically identified and discussed herein. [0016] Advantageously, embodiments described and claimed herein solve at least some of the shortcomings of the prior art by providing light traps that cloak the insect catching nature of the device. [0017] These and other features, aspects, objects, and advantages of the embodiments described and claimed herein will become better understood upon consideration of the following detailed description, appended claims, and accompanying drawings in which: [0018] Fig 1 is a perspective view of a first embodiment of a light trap; [0019] Fig 2 is a front view thereof; [0020] Fig 3 is a side view thereof; -5 [0021] Fig 4 is a bottom view thereof, the top view being essentially a mirror image thereof; [0022] Fig 5 is an exploded view thereof; [0023] Fig 6 is a sectional view thereof (through AA of Fig 7) which includes a visual representation of the radiation loom emitted from the light channels; [0024] Fig 7 is a front view thereof which also includes a visual representation of the radiation loom emitted from the light channels; [0025] Fig 8 is aside view thereof which also includes a visual representation of the radiation loom emitted from the light channels; [0026] Fig 9 is a perspective view of a second embodiment of a light trap with its front cover in the open position; [0027] Fig 10 is a close-up perspective view thereof which demonstrates how the light pipes are installed into the trap; and, [0028] Fig 11 is a perspective view of a third embodiment of a light trap.

It should be understood, of course, that the inventions described herein are not necessarily limited to the particular embodiments illustrated. Indeed, it is expected that persons of ordinary skill in the art may devise a number of alternative configurations that are similar and equivalent to the embodiments shown and described herein without departing from the spirit and scope of the claims. [0030] Like reference numerals will be used to refer to like or similar parts from Fig to Fig in the following detailed description of the drawings.

-6 DETAILED DESCRIPTION [0031] Three particular embodiments of a light trap 10, 110, 210 are described and shown herein, the first in Figs 1-8, the second in Figs 9-10, and the third in Fig1 1. Each of these embodiments is configured for installation on a wall surface, although it is contemplated that devices which utilize the claimed features could be adapted for mounting on other surfaces. The light traps 10, 110, 210 are designed to present a neutral aesthetic, as compared to current light traps, by substantially hiding from view, within the light traps 10, 110, 210 two insect attracting light sources 60a, 60b, 160a, 160b (not shown for third embodiment) and an insect immobilizing device 190 (not shown for first and third embodiment). Although the shown embodiments each utilize two insect attracting light sources 60a, 60b, 160a, 160b, it is contemplated that more or less could be utilized with satisfactory results. Contributing to the neutral aesthetic of the trap 10, 110, 210, the insect attracting light sources 60a, 60b, 160a, 160b are maintained substantially outside of a typical bystander's line of sight, except when the light trap 10, 110, 210 is viewed from extreme angles. By concealing the light sources 60a, 60b, 160a, 1 60b within the light trap, however, insect attracting light is prevented from directly projecting forward from the light trap. To enable the insect attracting light to reach the exterior of the light traps 10, 110, 210 and project in a forward (away from the wall surface) direction, the light traps 10, 110, 210 include structures for channelling light in the desired direction, which is usually the area desired to be free of insects. Further contributing to the neutral aesthetic, the light traps 10, 110, 210 have the capability to project visible-spectrum lighting on the wall. In this respect, the three embodiments 10, 110, 210 described and shown herein are insect traps which are disguised as standard wall wash light fixtures. The three embodiments of the light trap 10, 110, 210 are substantially similar, but include slight differences in structure and in assembly, as described in more detail below. The light traps 10, 110, 210 are similar in the respect that they are all adapted to project insect attracting light into the area desired to be free of insects. They all utilize two insect attracting light sources 60a, 60b, 160a, 160b that emit ultraviolet (or UV) light, and specifically ultraviolet light of the A bandwidth (referred to herein as "UV-A" light - 2). Although UV-A light is not visible to the naked human eye, insects are able to see and are particularly attracted to UV-A light, as discussed in more detail above. Satisfactory results can be obtained with a light source that emits light within the full spectrum of the UV-A bandwidth (i.e., between approximately 315 nm and 400 nm). However, it has been found for most insect species that better results can be obtained using an insect attracting light that emits UV-A light having a predominant wavelength between 345 and 375 nm, and ideally slightly less than 360 nm. To satisfy this criterion, black light blue lamps sold under the trade name Electrosect, which emit peak UV light at 353 nm, can be used.

-7 [0032] In the three embodiments 10, 110, 210 the insect attracting light sources 60a, 60b, 160a, 160b are positioned within light housings 12, 112, 212 behind the front cover 50, 150, 250 of the housing. The front cover 50 prevents the insect attracting light source from directly emitting light in a direction normal to the wall surface and within approximately 30-40 degrees on either side of normal. Since the insect attracting light sources 60a, 60b, 160a, 160b are generally shielded from view, the light traps 10, 110, 210 utilize light channels 14a, 14b, 114a, 114b, 214a, 214b and light pipes 70a, 70b, 270a, 270b to direct insect-attracting light outwardly from the light trap 10, 110 and away from the wall structure to which the traps 10, 110 are mounted. [0033] The light channels 14a, 14b, 114a, 114b, 214a, 214b are oblong in shape, are generally vertically oriented, and have and combined area of approximately 0.032 m2, although it is contemplated that devices having light channels of various other shape and orientations will fall within the scope of the claims. The light channels 14a, 14b, 114a, 114b, 214a, 214b include reflective surfaces 26a, 26b, 126a, 126b, 226a, 226b to effectively reflect light outwardly from the light trap 10, 110, 210. Due to the concealed nature of the insect attracting light sources 60a, 60b, 1 60a, 160b, emitted insect attracting light extends laterally from the sources 60a, 60b, 160a, 160b, in a direction generally parallel to the wall surface, toward the reflective surfaces 26a, 26b, 126a, 126b, 226a, 226b. The reflective surfaces 26a, 26b, 126a, 126b, 226a, 226b are oriented at an angle of approximately 120 degrees from the wall structure to thereby reflect the insect attracting light into the area desired to be free from insects. The reflective surfaces 26a, 26b, 126a, 126b, 226a, 226b can also serve as shields for blocking the transmission of insect attracting light onto the wall surface to which the light trap 10, 110, 210 is attached. Alternatively, the light trap could include separate shields to perform such a function. [0034] The light pipes or conduits 70a, 70b, 170a, 170b, 270a, 270b provide a second means for channel light in the desired direction by effectively "bending" concentrated, insect attracting light through the opening of the light channels 14a, 14b, 114a, 114b, 214a, 214b. In the shown embodiments, the light conduits 70a, 70b, 170a, 170b, 270a, 270b are acrylic plate like structures, although it is contemplated that other materials, such as glass, and other light conduit(s), including fibre-optic like devices, could be used in a similarly effective manner. The light conduits 70a, 70b, 170a, 1 70b, 270a, 270b at a first end abut the insect attracting light source 60a, 60b, 160a, 160b to capture concentrated insect attracting light. Light is transmitted through the light conduit 70a, 70b, 170a, 170b, 270a, 270b and is emitted from the second, opposing end of the light conduit 70a, 70b, 170a, 170b, 270a, 270b, which is disposed near -8 the opening of the light channel 14a, 14b, 114a, 114b, 214a, 214b. In the shown embodiments, the lengthwise dimension of the light conduit 70a, 70b, 170a, 170b, 27a, 270b is oriented generally parallel with the lengthwise dimension of the light channels 14a, 14b, 114a, 114b, 214a, 214b, although alternative embodiments are contemplated where the conduits are oriented in various other direction. Due to the light conduit's plate like structure, the light projected from the conduit is characterized by an intense line of insect attracting light. However, other patterns are contemplated depending upon the specific type of light conduit that is utilized. In use, the insect attracting light that is reflected off of the reflective surfaces 26a, 26b, 126a, 126b, 226a, 226b tends to leave the light channels in a diffused pattern 77a, 77b, while the insect attracting light that is transmitted through the light conduits is much more intense and is emitted from the light channels in a much more concentrated pattern 78a, 78b. The diffused and concentrated patterns of light which are emitted from the light channels merge to form a light pattern 79a, 79b having intensity graduations. The patterns of light emitted by the light channels 14a, 14b, 114a, 114b, 214a, 214b and associated structures are depicted in Figures 6-8. [0035] With specific reference now to Figures 1-8, the first embodiment of the light trap is shown. The light trap 10 generally comprises a light housing 12 which is configured to be mounted to a wall structure and to support various other components of the light trap 10. The shown embodiment of the light housing 12 is constructed of several components to define openings for the light channels 14a, 14b. Such components include a rear panel 20, two end panels (or mouldings) 30a, 30b, an internal chassis plate 40, a front cover 50, and an electronic ballast 42. The electronic ballast 42 is a choke which regulates the current when the UV lamp is running. [0036] The second embodiment of the light trap 110, as shown in Figures 9-10, also includes a light housing 112 which is constructed of several components. Such components include a rear panel 120, two end panels 130a, 130b, and a front cover. As may not be clearly shown in the figures, the second embodiment does not utilize an internal chassis plate, since such structure is integrated with the rear panel 120. [0037] The third embodiment of the light trap 210, as shown in Figure 11, is nearly identical to the second embodiment 110, except with respect to the front cover 250. [0038] In the embodiments shown and described herein, the rear panel 20 has a centre portion and two bent wing portions on the left and right side therefore, which extend at an -9 angle to the centre portion. It is contemplated that the rear panel 20 is fabricated from a metal material, such as Aluminium whereby the inside surface of the bent wing portions serve as the reflective surfaces 26a, 26b for the light channels 14a, 14b. It is also contemplated that the rear panel 20 could be fabricated from some other material, even a material such as plastic, which may not be sufficiently reflective. In such cases, an additional reflective structure may be provided in the light channel 14a, 14b, such as a metallic-like sticker which is adhered to the inside surface of the rear panel 20. As far as structure is concerned, the rear panel is provided with several apertures to enable the light trap 10 to be mounted to a wall surface, to provide a cable outlet, and to allow the electronic ballast 42 to be mounted thereto. Although the embodiments shown and described herein are intended to be wall-mounted, the light trap could be free standing, could be mounted to some sort of stand or pole, or could be mounted in any other manner. [0039] Attached to opposing sides of the chassis plate 40 of the first embodiment, and the chassis region of the rear panel 120 of the second embodiment, are the insect attracting light sources 60a, 60b, 160a, 160b. Although not depicted in the figures, the wiring and related components for powering the insect attracting light sources and visible-spectrum light sources are enclosed behind the chassis plate 40 of the first embodiment and the chassis region of the rear panel 120 of the second embodiment. [0040] Each of the end panels 30a, 30b, 130a, 130b include a plurality of slots or the like for receiving and/or engaging with opposing ends of the rear panel 20, 120 and internal chassis plate 40. For the end panels 30a, 30b of the first embodiment, a first slot is provided along a rear edge of each end panel for receiving the rear panel 20 and a second slot, which has the same general contour as the chassis plate 40, is provided extending from a rear edge of each end panel 30a, 10 30b for receiving the chassis plate 40. Each of the end panels 30a, 30b are provided with an additional pair of slots which are configured to receive the light conduits 70a, 70b. The end panels 30a, 30b also include slots which are configured to engage with the front cover 50. For such purpose, the bottom end panel 30b includes two inwardly-diverging, open bottomed slots which are configured for sliding engagement with the front cover. The top end panel 30a includes two inwardly-diverging, closed-bottom slots which are also configured for sliding engagement with the front cover. However, the closed-bottom of the slot in the top end panel 30a engages with the cover to hold the cover in place. The control board (not shown) is intended to be tucked in at the transition of the end panels 30a, 30b and chassis plate 40.

-10 [0041] For the end panels 130a, 130b of the second embodiment, a first slot is provided for receiving the rear panel 120. The top end panel 130a includes a second, elongated slot which is configured to receive a first end of the control board. The bottom end panel 130b includes a lip which is adapted to engage with the opposed end of the control board, which on a standard control board (such as the one sold by Brandenburg with product number BBG1012.5) is a folded over portion. Each of the end panels 130a, 130b also include a pair of slots which are configured to engage with the end portions of the light conduits 170a, 170b. The light conduits 170a, 170b have a length which is less than the length between the two end panels 130a, 130b whereby the conduits can be angled into the conduit supporting slots as depicted in Figures 9-1 O.The ends panels 130a, 130b also include apertures which serve as hinges for the front cover 150, which is adapted to pivot between open and closed positions. [0042] To hold the light housing 12 together, fasteners engage with the chassis plate 40 of the first embodiment, or the rear panel 120 through apertures which are provided on the end panels 30a, 30b, 130a, 130b. [0043] Both embodiments of the end panels 30a, 30b, 130a, 130b include generally conically or concave shaped, recessed portions 36a, 36b (not depicted in the Figs for the second and third embodiments) into which a visible spectrum light source can be attached. In one particular embodiment, the visible spectrum light source is an LED GU 10 light bulb. [0044] The structure of the three embodiments of the light conduits 70a, 70b, 170a, 170b, 270a, 270b are substantially similar although the first embodiment abuts the insect attracting light source 60a, 60b from the side while the second and third embodiments abut the insect attracting light source 160a, 160b from the rear. To facilitate such configuration, the conduits 70a, 70b, 170a, 170b, 270a, 270b have lengths that extend in more than one dimension, whereby the first embodiment 70a, 70b includes one bend along its length, while the second and third embodiments 170a, 170b, 270a, 270b include two bends. [0045] The front covers 50, 150, 250 are substantially similar, although, as discussed above, the first embodiment is configured for sliding engagement with the end panels 30a, 30b, while the second and third embodiments are configured for pivoting engagement with the end panels 130a, 130b. The front panels 50, 150, 250 extend in a lateral dimension a sufficient distance to shield the insect attracting light sources 60a, 60b, 1 60a, 160b from any light of sight extending normal to the light fixture and within 30-400 to either side thereof. The front covers 50, 150, 250 also extend a distance upwardly and downwardly of the end panels 30a, - 11 30b, 130a, 130b to shield the wall wash light elements 80a, 80b, 180a, 180b, which display visible light 4, from view. [0046] The front cover 250 of the third embodiment, as shown in Figure 11 , includes a plurality of windows 295 which provide an additional escape of UV light from the light trap 250. Although the shown embodiment utilizes a plurality of windows 295, any number can be used. The windows 295 are disposed in two separate groupings, one on the right side of the light trap and the other on the left side of the light trap. Each grouping of windows 295 is arranged in a triangular pattern, although any pattern can be used. Each window 295 is generally rectangular, although it is contemplated that the windows 295 can have any shape. In the shown embodiment, the windows 295 are translucent or screened to mask what is inside of the light trap (the UV lamps and insect immobilizer), although the windows 295 can be clear. Any material can be used for the windows, including glass and plastics (such as acrylic). [0047] To provide the windows 295 with a translucent appearance, the inside surface of the windows could be a roughened surface, similar to the cover housing as No. 6,108,965, which is incorporated by reference. As used herein, the term "roughened surface" means a surface that is broken, uneven, textured, bumpy or which otherwise does not have a smooth profile. Such a surface may be formed by sandblasting or moulding the windows 295 using a mould with a textured surface. It is believed that by providing the windows 295 with a roughened inner surface which is in facing relationship with the UV lamps, the transmission of insect attracting light from the UV lamps through the front cover 50 can be enhanced. While not wanting to be bound by theory, it is believed that the roughened surface acts as a magnifier of the light from the light source. [0048] Although the inventions described and claimed herein have been described in considerable detail with reference to certain embodiments, one skilled in the art will appreciate that the inventions described and claimed herein can be practiced by other embodiments to those presented for the purposes of illustration. Indeed, it is contemplated, that the light trap can take many different shapes, orientations, and forms, besides those described and shown herein. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
