    • BACKGROUND OF THE INVENTION Field of the Invention
  • This invention relates to light fixtures, more particularly to light fixtures having both normal or main light illumination and light emitting diode (“LED”) nightlight or accent light illumination, to LED downlights with main light illumination and LED nightlight illumination, to an LED ceiling/wall light fixture with a main light and with a nightlight, and related LED lighting arrangements.
  • This invention relates to light fixtures, and particularly to LED ceiling light fixtures with various types of illumination, to LED ceiling light fixtures with more than one type of lighting including but not restricted to nightlights, to LED ceiling lights with controllable correlated color temperature (“CCT”) and with an LED nightlight, and to LED lights with a nightlight, and where the LED light has variable CCT.

    • Description of the Prior Art
  • Various electrically operable lighting devices are known which are either nightlights or light sources including a main lighting source. However, none are believed to have heretofore been known where the nightlight (or other additional light source) directs illumination in particular directions which are predominantly separate from the direction of the illumination of the main light. This in particular applies to LED lighting fixtures. Thus, no light sources are known to exist, particularly with respect to LED light sources, where the main light source can be directed in many directions whereas the nightlight (or other additional light source) is directed to a specific area such as along a ceiling as an adjacent surface to receive illumination.
  • LED light fixtures such as LED ceiling light fixtures in general are well known in the art. For example, LED downlights generally include a housing mountable in a holder referred to as a canister or can, mounted in a ceiling or elsewhere. LED components located in the housing include a driver with electronic circuitry for providing electrical power to a group of LEDs and a diffuser for transmitting diffused LED illumination from the LED in downlight. The LED downlight typically emits luminosity with a fixed value of CCT, which luminosity can be varied in its intensity by a dimmer switching circuit that is installed in the room or other facility for controlling the electricity in the electrical interface in which the LED downlight is mounted. Commonly assigned U.S. Pat. No. 10,091,855 discloses an LED light fixture with a manually variable CCT. There are LED nightlights for emitting LED illumination of low intensity which are used to provide a lower end of illumination at night time. Such nightlights are typically mounted in electrical receptacles located near a floor or on a wall. Nightlights were not heretofore known to be an additional component of LED lights of any sort, including ceiling or wall lights or of any other type of lights at all.
  • Also not heretofore known are any ceiling lights such as flushmount lights having nightlights as an additional source of illumination. LED ceiling lights are also well known. See for example commonly assigned U.S. Pat. Nos. 9,500,352 and 9,541,270, each entitled Integral LED Light Fixture. These are often called flushmounted LED ceiling lights. Such LED light fixtures are widely used. However, they have not heretofore been accompanied with nightlights. Other types of LED light fixtures including canless downlights, puff lights, low profile flushmount lights, LED lights connectable to a junction box for receiving electric power therefrom, and the like, are not known where the main light is accompanies by the nightlight.

  • These and other objects will be apparent from the description to follow and from the appended claims.
  • The present invention in one respect provides an LED light fixture which in one form comprises an LED illumination source for being mounted on a ceiling to provide illumination for such purposes as to illuminate a space, and a nightlight for providing a subdued LED illumination.
  • The present invention in one embodiment provides an LED ceiling/wall light with LED nightlight which in one form comprises an LED illumination source for being mounted on a ceiling or wall to provide illumination for such purposes as to illuminate a space, and a nightlight for providing a subdued LED illuminating source. The LED illumination incorporates a variable CCT and can be dimmed. The nightlight can also be used as an accent light.
  • A ceiling/wall LED light with LED nightlight when in its preferred embodiment, can be installed primarily on ceiling, but could also be installed walls, floors and the like. The inventive ceiling/wall LED light with LED nightlight has some very new, important and useful features. It can provide illumination by means of a “main light,” as opposed to a nightlight as discussed below, in various manually selectable CCTs varying from a warm white light, a soft white light, a cool white light, a bright white light and daylight (or a smaller number of variations), and which can be dimmed with a dimmer switch. In order to change the CCT of the LED ceiling/wall light with LED nightlight in its preferred embodiment, a finger actuable switch is provided for determining the color temperature of the luminosity which varies from warm white to daylight as indicated above. The LED ceiling/wall light with LED nightlight according to a preferred embodiment of the invention is discussed below, wherein the LED nightlight can be selectively activated to provide a low luminosity of preferably 40 lumens at 2000k color temperature (CCT), which requires very small input energy, preferably around 3.5 watts. The finger actuable switch is located in a compartment or cavity defined by a base and a lens or diffuser, the latter being removable to render them manually operable.
  • The LED ceiling/wall light with LED nightlight according to a preferred embodiment of the invention is usually mounted in a ceiling or wall, and has a downward (or forward) facing face, and around which is an annular or peripheral portion. The downward or forward face oftentimes has a circular cross-section, but the invention is not limited to either a circular or a generally cylindrical shape. It could have corners or other shapes, so the inventive LED lighting fixture could have the general configuration of a cylinder, a rectangular, parallelepiped, a truncated cone, a hexagonal prism, a spheroid end portion and combinations of the foregoing, and the like, or have an irregular configuration. The LED nightlight provides luminosity through an annular or other peripheral edge which preferably surrounds an upper portion or rearward face (proximate the ceiling or wall and distal the floor or an opposite wall) of the inventive LED ceiling/wall light with LED nightlight. The LED nightlight could be located on the rearward or forward part of the LED ceiling/wall light with LED nightlight, but it is advantageously disposed on the rearward part in the preferred embodiment. The forward face typically would incorporate a diffuser. As mentioned above, the LED nightlight is advantageously proximal the ceiling or wall in which the LED ceiling/wall light with LED nightlight is mounted. The inventive LED ceiling/wall light with LED nightlight incorporates electronic circuitry for two illumination sections, the higher luminosity main light section and the lower illumination nightlight section. The electronic circuitry for each of the two illumination sections are advantageously operated independently of each other. Furthermore, the LED ceiling/wall light with LED nightlight according to the invention can incorporate a variable CCT. It could be dimmable. Either or both of the main light section and the nightlight section usually modifies or treats either or both of the main light and the nightlight by passing the emitted light through one or more transmitting functional items such as a lamp shade, a diffuser or lens, a transparent cover, a light guide sheet or plate, a reflector, a transparent cover with light modifying features, reflective sheeting, and a transmittance mask.
  • The present invention in one of its forms provides an LED lighting fixture preferably for being mounted on a ceiling such as a flushmount, a puff light, a low profile flushmount, a downlight or a canless downlight. A downlight when in one of its preferred embodiment can be installed in many installed recessed housings. The inventive downlight has some very new, important and useful features. It can provide illumination in various pre-selected CCTs varying from a warm white light, a soft white light, a cool white light, a bright white light and daylight. In order to change the CCT of the downlight in its preferred embodiment, a finger actuable switch is provided for determining the CCT of the luminosity which varies from warm white to daylight as indicated above. Moreover, the downlight according to a preferred embodiment of the invention further incorporates a nightlight which can be selectively activated to provide a low luminosity of preferably 40 lumens at 2000k CCT, requiring very small input energy, preferably around 3.5 watts
  • The downlight is usually mounted in a ceiling, and has a downward (or forward) directed face, and around which is an annular or peripheral portion. The face usually has a circular cross-section, but the invention is not limited to a circular shape. It could have corners or other shapes. The nightlight provides luminosity through an annular edge which preferably surrounds the visible portion or forward face of the inventive downlight. The forward face typically would incorporate a diffuser, and the nightlight is proximal both the diffuser of the inventive downlight and the ceiling in which the downlight is mounted. The inventive downlight incorporates electronic circuitry for two illumination sections, the downlight section and the nightlight section. Each section has a light output provided by separate sets of LEDs. However, the inventive concept also includes a ceiling-mounted LED nightlight.
  • The operation of this aspect of the inventive downlight in one of its preferred form is very simple. Once the inventive downlight is properly installed, typically in a ceiling, can or housing, the electronic circuitry is operated by a switch such as a conventional wall switch. When the wall switch is changed from the “off” position to the “on” position, a main light set of LEDs for the downlight section is actuated, causing the downlight LEDs to emit illumination according to the pre-set CCT. Whenever the illumination of the nightlight is sought, the user moves the wall switch from the “on” position for activating the main set of LEDs, to the off position and finally back to the on position to turn the main set of LEDs off and to actuate nightlight LEDs. The switching arrangement is due to the switching circuitry connected to the wall switch and to the downlight nightlight.
  • The rearward portion of the nightlight in one of its preferred forms has a digitally movable switch which can be moved between the various color temperatures to which the downlight can be set for generating illumination of the desired color temperature. The switch makes appropriate changes in the electric circuitry to make the selected variation in the CCT. The desired color temperature can be set by removing the downlight from the housing in which it is installed or prior to installation, and setting the switch to the desired color temperature.
  • As used herein, the word “forward” refers to the direction of illumination, and the term “rearward” refers to the direction behind the source of illumination. Thus “rearward” means behind the light fixture and proximal the ceiling or wall, and “forward” means in front of the light fixture and proximal the floor.
  • The term “array of LEDs” is used in this application. The exact nature of the LEDs is not significant with respect to the invention. The term “array of LEDs” means any type of LEDs. This includes one or more LEDs, string or strip LEDs, or any length of the LED assembly, equally spaced, selectively spaces or randomly spaced LEDs, all of the latter fall within the meaning of the term “array of LEDs” as used herein.
  • The term “printed circuit board” is used to define the structure to which an array of LEDs is mounted. Although printed circuit board usually includes circuitry included in the printed circuit board, the term printed circuit board is used more broadly in this document. The term “printed circuit board” means herein any support for LEDs, whether or not all or part of an electric circuit is included in the printed circuit board.

  • FIG. 1 illustrates the use of a downlight according to a preferred embodiment of the invention, with only the nightlight or accent mode (the nightlight and accent are the same mode of operation) in its low energy and low luminosity mode. The nightlight or accent mode is actuated by turning the operating switch for the inventive downlight portion (which can be a wall switch, for example) from the off position to the on position, then to the off position and back to the on position, thereby first actuating the downlight. As used hereinafter, the overall lighting unit in this embodiment is referred to as “the downlight.” The nightlight requires a very small input electrical energy, oftentimes of about 3.5 watts. Each of FIGS. 1 and 2A-2E demonstrate the use of the inventive downlight in a bathroom. As indicated initially, FIG. 1 shows nightlight emitting illumination in the nightlight/accent mode. FIG. 2A shows illumination when the downlight is set by a downlight mode switch described hereinafter to the warm white mode of 2700k. In FIG. 2B, the downlight mode switch is set to 3000k to set the CCT in a soft white mode. When a cool white mode is desired, the CCT switch is set to 3500k and the luminosity is a cool white mode as shown in FIG. 2C. A bright white mode illumination occurs when the CCT switch is set to the 4000k setting illustrated in FIG. 2D. Finally, when a daylight mode is desired, the downlight CCT switch is set to 5000k as shown in FIG. 2E.
  • FIGS. 3A-3F show a pair of downlights according to the preferred embodiment of the invention in adjacent sections of a hallway. The nightlight/accent mode is shown in FIG. 3A.
