AN LED LIGHTING SYSTEM

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Application No. 14/941 ,594, filed November 14, 2015, entitled An LED Lighting System, which claims the benefit of U.S. Application No. 62/103,099, filed January 14, 2015, entitled LED Lamp System, both of which are hereby incorporated by reference in their entirety.

FIELD OF THE DISCLOSURE

[0002] This invention generally relates to light systems or fixtures, and, more particularly, to an LED lighting system.

BACKGROUND

[0003] The background information is believed, at the time of the filing of this patent

application, to adequately provide background information for this patent application. However, the background information may not be completely applicable to the claims as originally filed in this patent application, as amended during prosecution of this patent application, and as ultimately allowed in any patent issuing from this patent application. Therefore, any statements made relating to the background information are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

[0004] Surface mount and recessed fluorescent light fixtures, such as strip and troffer light fixtures, have typically been installed to provide general lighting of large indoor spaces. For example, surface mount and recessed type fluorescent strip light fixtures may include stem and pendant mounted suspended variations as well as those fixtures mounted directly to a ceiling or in the ceiling.

[0005] Typically, such strip fixtures include a channel in the form of an inverted trough or troffer, with the channel being attached to or recessed in the ceiling. Lamp holders or sockets are attached to the channel or troffer. A ballast is attached within the channel and wiring attaches the ballast to the lamp holders. Power is supplied to the ballast by wiring brought into the channel through the top or end of the channel. A ballast cover is used to cover the ballast and wiring. Linear fluorescent lamps are then placed in the lamp holders for operation of the fixture. The lamps may be left bare or covered for providing light to the space below. Because of their low cost and utilitarian use, fluorescent strip light fixtures are currently installed in abundance. For example, typical uses include warehouses, retail stores, such as grocery, drug, and

department stores, where the fixtures are commonly mounted in continuous rows.

[0006] Since the introduction of the fluorescent lamp at the 1939 World Fair, fluorescent lighting technology has greatly advanced. For example, over the years, lamp and ballast manufacturers have developed fluorescent lamp-ballast systems with improved efficiencies. More recently, light emitting diode (LED) LED lamps have been developed. An LED lamp uses solid-state LEDs as the source of light. An LED may comprise a conventional semiconductor light emitting diode or an organic or polymeric light emitting diode. LED lamps may have one or more advantages over fluorescent lamps, for example, LED lamps do not contain mercury, they may turn on more instantaneously, they may have a longer service life, and they may have a greater efficiency.

[0007] It may be desired to provide advantages of LEDs to light fixtures and lighting systems that have traditionally used fluorescent lamps. SUMMARY
