This application relates to light fixtures and retrofit kits for light fixtures, and, more particularly, to light fixtures and retrofit kits with a wireless module holder.
Many traditional light fixtures are not “smart” enabled, meaning that they are not connected to other devices or networks via different wireless protocols (e.g., Bluetooth®, Wi-Fi®, near field communication, LiFi, 3G, etc.) and as such cannot operate interactively and/or autonomously. Moreover, traditional light fixtures are often difficult to retrofit with Bluetooth or other wireless capabilities because such changes require modifying the light fixture in the field, which in most cases requires an inspector to be on site and approve the modifications. Therefore, there is still a need for a system that can provide for easy installation of a wireless communication module into a new or existing light fixture.

In some examples, the housing 104 includes at least one spacer 110 that supports the wireless communication module within the housing chamber 106. When positioned on the spacer 110, the wireless communication module is spaced apart from the chamber surface 108. In the example of
In various examples, as illustrated in
In certain embodiments, at least one spacer 122 is provided on the module holder 112. In the example of
The housing 104 is removably attached to the base 102 such that the housing 104 can be selectively connected with or disconnected from the base 102. In various examples, the base 102 and the housing 104 of the wireless holder 100 may only be assembled in one configuration, which reduces or eliminates assembly error. In the example of

In the example of
An optic 914 (such as a lens, diffuser, or other suitable optic) and a reflector 916 are positioned within the housing 902 and adjacent to an opening 918 defined by the base 910. The optic 914, reflector 916, or both may be positioned through various mechanisms such as via snap-fitting onto the cover 912 or base 910 or through various other suitable connection mechanisms. The optic 914 can be made of any non-metallic material that permits light to exit through the optic 914, including, but not limited to, polymeric materials, glass, silicone and various other suitable materials for light distribution.
In some examples, the LEDs 904 are mounted on the housing 902 adjacent to a portion of an edge of the optic 914. In such cases, the optic 914 is also a light guide; however, in other examples, a separate light guide may be provided in addition to the optic 914, and the LEDs 904 may be positioned adjacent to at least a portion of an edge of the light guide. When the light guide is a separate component, the light guide may be made of any of various suitable materials for directing the light source emission including, but not limited to, air, polymers, glass, various transparent materials, or various other suitable materials or combinations of materials. In some examples, the light source emission from the LEDs 904 is directly into the optic 914. In other examples, an optical diverter is provided between the LEDs 904 and the optic 914 such that the light source emission from the LEDs 904 is directed to the optic 914 through the optical diverter. In further examples, the light fixture 900 need not be an edge-lit luminaire, and the LEDs 904 may be provided at other locations on the housing 902.
The LEDs 904 are shown provided on printed circuit boards 920 (“PCBs”). In some cases, the PCBs 920 with LEDs 904 are supported on the base 910, although they need not be in other examples. In the example of
As illustrated in
The wireless holder 100 is removably attached to the housing 902 such that the light fixture 900 can be “smart” enabled through the wireless communication module 922. In the example illustrated in
In various examples, the base 102 of the wireless holder 100 may be permanently attached to the housing 902 or may be removably attached to the housing 902. In some examples, the housing 104 can be detached from the base 102 such that the housing 104 and/or wireless communication module 922 can be repaired or replaced as desired without removing the base 102 or disassembling the light fixture 900.
As mentioned, the wireless holder 100 may allow for the light fixture 900 to be “smart” enabled. For example, the light fixture 900 may be controllable through a handheld wireless device such as a smartphone, to dim the light fixture 900, cause the light fixture 900 to change the color temperature of the light it emits, or to control other aspects of the operation of the light fixture 900. In addition, the base 102 and the housing 104 of the wireless holder 100 may only be assembled in one configuration, which reduces or eliminates assembly error. Positioning the wireless holder 100 such that the housing 104 is on the light-emitting side 906 of the light fixture 900 may also allow for maximum signal strength from the wireless communication module 922 to a user's device below.
