Apparatuses and methods for restraining a lighting fixture selector

Systems and methods that permit initial selection of a lighting fixture output characteristic and inhibit later change of the lighting fixture output characteristic are disclosed. Embodiments include one or more devices that inhibit a lighting fixture control switch from being moved between two different positions. In some embodiments the control switch extends through an aperture in the a housing of the lighting fixture and the one or more devices are inserted into the aperture and embrace the control switch in one of the control switch's operational positions. In some embodiments the configuration of the apertures and the devices permits the devices to be inserted into the apertures in a single orientation. Some embodiments include devices with an outer surface that defines the switch embracing portion, and some embodiments include devices that are difficult to remove by hand after insertion into the aperture.

FIELD

Embodiments of this disclosure relate generally to lighting fixtures, also referred to as light fixtures or luminaires.

BACKGROUND

Lighting fixtures can include user actuated control devices, such as switches, that allow a user to change at least one characteristic of the light emanating from the lighting fixture during operation. However, it was realized by the inventors of the current disclosure that problems exist with some lighting control devices that allow users to change the characteristic of the light emanating from the lighting fixture after the lighting fixture has been installed and that improvements in the ability to inhibit variation of these lighting fixture control devices are needed. Certain preferred features of the present disclosure address these and other needs and provide other important advantages.

SUMMARY

Embodiments of the present disclosure provide an improved apparatuses and methods for restraining a lighting fixture selector.

Power companies frequently offer discounts or rebates for customers who install energy efficient lighting fixtures. However, customers can desire different options for achieving these discounts, such as, desiring incrementally brighter light for a smaller discount. There can also be regions where the color temperature of the light is regulated or incentivized. For manufactures, manufacturing a single light fixture that can be adapted for different light intensities and/or different color temperatures is advantageous since one fixture can be used to meet different demands, but power companies can resist offering discounts or rebates for light fixtures that allow a user to change the power consumption and/or color temperature of the lighting fixtures. Power companies can offer discounts and/or rebates for lighting fixtures that allow an installer, such as an electrician, to easily set the lighting fixture to a particular power consumption or color temperature setting and limit the ability of a user to adjust the power consumption and/or color temperature of the lighting fixture after the lighting fixture has been installed by the electrician.

Embodiments of the present disclosure provide methods and apparatuses for limiting the ability of a user to change the illumination output of a light fixture after the illumination has been set. In one example embodiment devices are used that restrict the ability of a user to move a switch (for example a toggle switch, a rotary switch or other form of mechanical switch), that controls the illumination output of a lighting fixture. The devices include portions that allow the devices to be securely mounted to the switch housing and portions that restrain the switch in a specific orientation. In some examples, the devices are inserted into an aperture through which a switch extends and include an aperture that receives the switch and holds it in a particular position. Embodiments can be difficult to remove from the switch housing and can be of unitary construction. Use of these devices can allow users to receive rebates or incentives from power companies for operating light fixtures with certain characteristics, such as low power consumption.

Depicted inFIG. 1is a luminaire100with one or more light sources (for example, light emitting diodes (LEDs), not depicted), a housing104and a controller102. The one or more light sources in luminaire100are functionally controlled, at least in part, by controller102. Controller102includes one or more user selectable illumination control selectors110(for example, toggle switches103and105) that control one or more characteristics of the light being illuminated by the light sources. The toggle switches103and105extend outside the housing104of luminaire100through one or more illumination selector accesses (for example, apertures108allowing access by a user, such as an electrician. Illumination selector legends116and117may optionally be included to assist a user in placing the toggle switches103and105in the desired positions.

Depicted inFIG. 2are switch restraining members (which are occasionally referred to as selector switch restraining collars) that may be included as at least part of a locking member kit170that is configured and adapted for use with luminaire100according to one embodiment of the present disclosure. Locking member kit170includes one or more switch restraining members, for example locking member172, locking member173and locking member174. Each of the locking members172,173and174includes an illumination selector receiving portion, for example, toggle switch embracing portion176, toggle switch receiving portion177and toggle switch receiving portion178, respectively, which can embrace the toggle switch (for example, snugly embrace the toggle switch with at least two opposing sides of the outer surface of the toggle switch exert a nonzero contact force (for example, a nonzero pressure) on the inner surface of the aperture108into which it is inserted). One or more of the locking members172,173and174in the locking member kit170optionally include a housing engagement feature, for example, a groove180, that increases the difficulty in removing the locking member from the housing once the locking member is installed. One or more of the locking members172,173and174may also optionally include identification features184,185and/or186to assist a user in identifying the appropriate locking member172,173or174.

The locking members172,173and174include switch embracing portions that hold an illumination selector (for example, toggle switches103and105) in a particular position when mounted to an illumination selector access (for example, aperture108) of housing104. UsingFIG. 3as an example, when locking member172is mounted to the left aperture108the illumination selector (toggle switch103) is held in the lower (50 Watt) position, and when locking member173is mounted to the right aperture108the illumination selector (toggle switch105) is held in the upper (5000 Kelvin) position. Similarly, if locking member174is mounted to the left or right aperture inFIG. 3, the illumination selector (toggle switch103or toggle switch105, respectively) will be held in the middle (40 Watt or 4000 Kelvin, respectively) position.

One or more of the locking members (for example, locking members172,173and/or174) are optionally asymmetric in shape requiring the locking member to be inserted into its corresponding aperture (for example, apertures108) in a single orientation. For example, the locking members172,173and174depicted inFIGS. 2 and 3-8have orientation features181,182and183, respectively (which may also take the form of traditional keyed portions such as slots and tabs or asymmetrical geometric shapes) requiring the locking members172,173and174to be placed in a particular orientation prior to insertion into an aperture108. Different locking members hold the illumination selector in different positions and inhibit movement of the illumination selector away from the particular position in which the illumination selector is being held. Although the locking members depicted inFIG. 2hold an illumination member in one (1) of three (3) different positions, other embodiments include locking members that hold an illumination member in two (2) different positions, which further embodiments include locking members that hold an illumination member in four (4) or more different positions.

In use, a user selects the appropriate positions for toggle switches103and105to comply with the desired light output for luminaire100and inserts the appropriate one or more locking members (for example, locking member172,173and/or174) into the one or more housing apertures108(which surround toggle switches103and105) and secures one or more toggle switches103and105in the appropriate positions. When inserted into an aperture108, the outer surface of the locking member172,173and/or174engage the inner surface of the aperture108into which the locking member is inserted and the interaction (for example, friction, pressure or other holding force) between the outer surface of the locking member172,173and/or174and the inner surface of the aperture108into which the locking member is inserted hold the locking member in position within the aperture108. The embracing portion176,177and/or178of the inserted locking member172,173and/or174(each of which is a portion of the outer surface of the respective locking member) receives the toggle switch103or105(and may embrace the toggle switch103or105by contacting at least a portion of the toggle switch103or105) and prevents the toggle switch103or105from moving to a different position. In at least one embodiment, the outer surface of the locking member172,173and/or174is larger than the aperture108resulting in the locking member172,173and/or174being snugly received within the aperture108. If included with locking members172,173and174, grooves180engage with the border edge of apertures108and increase the effort required to remove locking members172,173and174from apertures108.

With the appropriate locking members172,173and174positioned within apertures108for the desired light output, it is difficult to change the positioning of the toggle switches103and105. For example, a user may need to locate and use a tool, and in some embodiments a specially designed tool, to extract locking members172,173and174from apertures108. In some embodiments extracting locking members172,173or174from apertures108will physically damage locking members172,173and174, providing a tamper evident system for assisting possible inspectors in determining whether the positioning of toggle switches103and105have been changed since installation.

With the appropriate locking members172,173and174attached to housing104, illumination selectors103and105are held in specific positions limiting the output of the light emitters (for example, LED lamps) to particular characteristics (for example, a specific power and/or color), allowing users of luminaire100to take advantage of various discounts and/or rebates offered by power companies and/or governmental agencies for using certain types of power or illumination.

Depicted inFIG. 4is a luminaire200according to another embodiment of the present disclosure. Luminaire200includes one or more light sources (for example, light emitting diodes (LEDs), not depicted), a housing204and a controller202. The one or more light sources in luminaire200are functionally controlled, at least in part, by controller202. Controller202includes one or more user selectable illumination control selectors210(for example, toggle switches203and205) that control one or more characteristics of the light being illuminated by the light sources. The toggle switches203and205extend outside the housing204of luminaire200through one or more illumination selector accesses (for example, apertures206) allowing access by a user, such as an electrician. Illumination selector legends212and213may optionally be included to assist a user in placing the toggle switches203and205in the desired positions.

Depicted inFIG. 5are switch restraining members that may be included as at least part of a locking member kit230configured and adapted for use with luminaire200according to yet another embodiment of the present disclosure. Locking member kit230includes one or more switch restraining members, for example locking member232and locking member234. Each of the locking members232and234includes an illumination selector receiving portion, for example, toggle switch embracing portion236and toggle switch embracing portion238, respectively, which can embrace the toggle switch (for example, snugly embrace the toggle switch with at least two opposing sides of the outer surface of the toggle switch exert a nonzero contact force (for example, a nonzero pressure) on the inner surface of the aperture206into which it is inserted). One or more of the locking members232and234in the locking member kit230optionally include a housing engagement feature, for example, a groove240, that increases the difficulty in removing the locking member from the housing once the locking member is installed.

Since the external shape of locking members232and234is rectangular, it is possible to insert each locking members232and234into apertures206in two orientations. For example, each of locking members232and234can be inserted into apertures206(seeFIG. 4) in the orientations depicted inFIG. 5and in orientations in which the locking members232and234have been rotated 180 degrees from the orientations depicted inFIG. 5. With locking members232and234rotated 180 degrees from the orientations depicted inFIG. 5, switch embracing portion236of locking member232will be oriented toward the upper end of the locking member232and the switch embracing portion238of locking member234will be in a similar, if not the same, orientation as depicted inFIG. 5since switch embracing portion238is centrally located in locking member234.

In use, a user selects the appropriate positions for toggle switches203and205to comply with the light output requirements for luminaire200and inserts the appropriate one or more locking members (for example, locking member232and/or234) into the one or more housing apertures206(which surround toggle switches203and205) and secures one or more toggle switches203and205in the appropriate positions. When inserted into an aperture206, the outer surface of the locking member232and/or234engage the inner surface of the aperture206into which the locking member is inserted and the interaction (for example, friction, pressure or other holding force) between the outer surface of the locking member232and/or234and the inner surface of the aperture206into which the locking member is inserted hold the locking member in position within the aperture206. The embracing portion236and/or238of the inserted locking member232and/or234(each embracing portion being at least a portion of an inner surface of an aperture within the respective locking member) receives the toggle switch203or205(and may embrace the toggle switch203or205by contacting at least a portion of the toggle switch203or205) and prevents the toggle switch203or205from moving to a different position. In at least one embodiment, the outer surface of the locking member236and/or238is larger than the aperture206resulting in the locking member236and/or238being snugly received within the aperture206. If included with locking members232and234, grooves240engage with the border edge of apertures206and increase the effort required to remove locking members232and234from apertures206.

With the appropriate locking members232and234positioned within apertures206for the desired light output, it is difficult to change the positioning of the toggle switches203and205. For example, a user may need to locate and use a tool, and in some embodiments a specially designed tool, to extract locking members232and234from apertures206. In some embodiments extracting locking members232and234from apertures206will physically damage locking members232and234, providing a tamper evident system for assisting possible inspectors in determining whether the positioning of toggle switches203and205have been changed since installation.

With the appropriate locking members232and234attached to housing204, illumination selectors210are held in specific positions limiting the output of the light emitters (for example, LED lamps) to particular characteristics (for example, a specific power and/or color), allowing users of luminaire200to take advantage of various discounts and/or rebates offered by power companies and/or governmental agencies for using certain types of power or illumination.

Depicted inFIG. 7is a luminaire300according to a further embodiment of the present disclosure. Luminaire300includes one or more light sources (for example, light emitting diodes (LEDs), not depicted), a housing304and a controller302. The one or more light sources in luminaire300are functionally controlled, at least in part, by controller302. Controller302includes one or more user selectable illumination control selectors310(for example, toggle switches303and305) that control one or more characteristics of the light being illuminated by the light sources. The toggle switches303and305extend outside the housing304of luminaire300through one or more illumination selector accesses (for example, apertures307) allowing access by a user, such as an electrician. Illumination selector legends314and315may optionally be included to assist a user in placing the toggle switches303and305in the desired positions.

Depicted inFIG. 8are switch restraining members that may be included as at least part of a locking member kit350configured and adapted for use with luminaire300according to yet another embodiment of the present disclosure. Locking member kit350includes one or more switch restraining members, for example locking member352and locking member353. Each of the locking members352,353and354includes an illumination selector receiving portion, for example, toggle switch embracing portion356, toggle switch embracing portion357and toggle switch embracing portion358, respectively, which can embrace the toggle switch (for example, snugly embrace the toggle switch with at least two opposing sides of the outer surface of the toggle switch exert a nonzero contact force (for example, a nonzero pressure) on the inner surface of the aperture307into which it is inserted). One or more of the locking members352,353and354in the locking member kit350optionally include a housing engagement feature, for example, a groove360, that increases the difficulty in removing the locking member from the housing once the locking member is installed.

Since the external shape of locking members352,353and354is rectangular, it is possible to insert each locking members352,353and354into apertures307in two orientations. For example, each of locking members352,353and354can be inserted into apertures307(seeFIG. 7) in the orientations depicted inFIG. 8and in orientations in which the locking members352,353and354have been rotated 180 degrees from the orientations depicted inFIG. 8. With locking members352,353and354rotated 180 degrees from the orientations depicted inFIG. 8, the switch embracing portion356of locking member352will be oriented toward the upper end of the locking member352, the switch embracing portion357of locking member353will be centrally located in locking member353, and the switch embracing portion358of locking member354will be oriented toward the lower end of the locking member354.

However, the locking members in locking member kit350include orientation members that will result in the apertures defined by the switch embracing portions356,357and358being located in different positions relative to the illumination selection accesses (apertures)307if inserted into apertures307after being rotated 180 degrees. For example, the switch embracing portion356of locking member352is located a distance362from the edge of locking member352that is different from the distance364at which the switch embracing portion358of locking member354is located from the edge of locking member354. As such, when locking member352is rotated 180 degrees from the orientation depicted inFIG. 8and inserted into an aperture307, the switch embracing portion356will be located a distance362from the top edge of aperture307(“top” as depicted inFIG. 7), which will be a different distance from the distance364that the switch embracing portion358of locking member354will be located from the top of aperture307when locking member354is inserted into an aperture307while in the orientation depicted inFIG. 8. Similarly, when locking member353is rotated 180 degrees from the orientation depicted inFIG. 8and inserted into an aperture307, the switch embracing portion357will be located a different distance from the top edge of aperture307(“top” as depicted inFIG. 7) than the switch embracing portion357would be located if the locking member353was not rotated from the orientation depicted inFIG. 8and inserted into aperture307.

Embodiments where distances362and364are equal are similar to the locking members in locking member kit230depicted inFIG. 5.

In use, a user selects the appropriate positions for toggle switches303and305to comply with the light output requirements for luminaire300and inserts the appropriate one or more locking members (for example, locking member352,353and/or354) into the one or more housing apertures206(which surround toggle switches203and205) and secures one or more toggle switches203and205in the appropriate positions. When inserted into an aperture206, the outer surface of the locking member232and/or234engage the inner surface of the aperture307into which the locking member is inserted and the interaction (for example, friction, pressure or other holding force) between the outer surface of the locking member352,353and/or354and the inner surface of the aperture307into which the locking member is inserted hold the locking member in position within the aperture307. The embracing portion356,357and/or358of the inserted locking member352,353and/or354(each embracing portion being at least a portion of an inner surface of an aperture within the respective locking member) receives the toggle switch303or305(and may embrace the toggle switch303or305by contacting at least a portion of the toggle switch303or305) and prevents the toggle switch303or305from moving to a different position. In at least one embodiment, the outer surface of the locking member352,353and/or354is larger than the aperture307resulting in the locking member352,353and/or354being snugly received within the aperture307. If included with locking members352,353and354, grooves360engage with the border edge of apertures307and increase the effort required to remove locking members352,353and354from apertures307.

With the appropriate locking members352,353and354positioned within apertures307for the desired light output, it is difficult for a user to change the positioning of the toggle switches303and305. For example, a user may need to locate and use a tool and, in some embodiments, a specially designed tool to extract locking members352,353and354from apertures307. In some embodiments extracting locking members352,353and354from apertures307will physically damage locking members352,353and354, providing a tamper evident system for assisting possible inspectors in determining whether the positioning of toggle switches303and305have been changed since installation.

With the appropriate locking members352,353and354attached to housing304, illumination selectors310are held in specific positions limiting the output of the light emitters (for example, LED lamps) to particular characteristics (for example, a specific power and/or color), allowing users of luminaire300to take advantage of various discounts and/or rebates offered by power companies and/or governmental agencies for using certain types of power or illumination.

While locking member kits170,230and350depict two (2) or three (3) locking members, other embodiments include four (4) or more locking members. Similarly, while luminaires100,200and300depict two (2) switches for controlling an illumination characteristic of the light emitter(s), other embodiments include luminaires with one (1) switch, and still other embodiments include luminaires with three (3) or more switches.

The locking members in one or more of the embodiments may comprise, or be solely constructed of, silicone or some other type of material that allows insertion of the locking member into an aperture in a lighting fixture and difficulty removing the locking member from the aperture. In some embodiments the locking members comprise, or are solely constructed of, materials that are commonly referred to as plastics, and may be elastomeric in nature.

Reference systems that may be used herein can refer generally to various directions (e.g., upper, lower, forward and rearward), which are merely offered to assist the reader in understanding the various embodiments of the disclosure and are not to be interpreted as limiting. Other reference systems may be used to describe various embodiments, such as referring to the direction of projectile movement as it exits the firearm as being up, down, rearward or any other direction.

While examples, one or more representative embodiments and specific forms of the disclosure have been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive or limiting. The description of particular features in one embodiment does not imply that those particular features are necessarily limited to that one embodiment. Some or all of the features of one embodiment can be used or applied in combination with some or all of the features of other embodiments unless otherwise indicated. One or more exemplary embodiments have been shown and described, and all changes and modifications that come within the spirit of the disclosure are desired to be protected.
