BACKGROUNDOverhead light fixtures used in parking garages, office space, industrial warehouses, and the like often include fluorescent light bulbs or lamps, and typically include 3 fluorescent light bulbs. Some disadvantages of fluorescent light bulbs or lamps that are used in such fixtures are that they are not very efficient and thus consume a lot of power. For example, such fluorescent light bulbs or lamps are not very amenable to being dimmed and when they are dimmed their power factor or efficiency drops down to about 70%. In addition, fluorescent light bulbs may not provide enough light for certain fixture locations. Further, fluorescent light bulbs have an omni-directional light output pattern, not directional, and thus there is inherent loss of light radiated in a backwards direction (upwards instead of downwards). Further, fluorescent light bulbs become less efficient over time and use, and are not suitable for use in certain applications such as cold weather locations. Still further, fluorescent light bulbs tend to give off a large amount of heat, which can lead to increased air conditioning costs when used in high temperature locations and climates.

The power supply module 102 receives, for example, a 120 Volts AC input signal on input line 130 and converts the input voltage to two parallel output DC voltage signals on lines 132, 134 to power two LED bulbs or lamps 104. The power supply module converts the input voltage and current to a DC voltage and current for powering the microcontroller 108. The power supply module can also include the microcontroller 108, which is configured to be responsive to the switch 110 settings to provide an output signal on lines 132, 134 that adjust the amount of light output by the LED light assemblies 104. The sensor circuit 106 includes a motion sensor circuit that detects motion to provide for turning on the LED light assemblies 104 in response to the detected motion. The sensor circuit also includes an ambient light sensor circuit, which outputs a signal corresponding to an amount of detected ambient light. The microcontroller 108 in combination with the motion sensor of sensors 106 combine to provide an output signal that turns on the LED light assemblies 104 in response to motion detected by the motion sensor. In addition, the microcontroller 108 in combination with the ambient light sensor of sensors 106 combine to provide an output signal that adjusts the amount of light output by LED light assemblies 104. For example, if no ambient light is detected by the light sensor 144, then the light assemblies can provide a maximum light output. Alternatively, if a sufficient amount of ambient light is detected, such as may occur in daylight, then LED light assemblies can be controlled, for example to only provide half of the light capacity of the LED light bulbs or lamps.
As noted above, the lighting assembly 104 can be used as a replacement lighting assembly in existing fixtures that use fluorescent light bulbs. Alternatively, as will be detailed with respect to some embodiments of the disclosure, the lighting system and lighting assemblies can be provided as a completely new fixture that can, for example, replace an existing lighting fixture or to retrofit an existing lighting fixture.
Referring again to
As noted above, the lighting assembly 100 includes a power supply 102, which is configured in combination with the LED light assemblies 104 to retro-fit or replace existing overhead light fixtures 114 so that the LED light assemblies 104 can be used in the existing overhead light fixtures 114 or in various embodiments of the lighting system disclosed herein.

The power supply also includes a stable current and voltage maintenance circuit 140, which is illustrated in
It is to be noted that the LED light assemblies 104 according to this disclosure provide a lot more light than is typical for fluorescent light bulbs or lamps that they are intended to replace. In particular, it has been measured and tested that an existing fixture 114 retrofitted with 2 LED assemblies 104 according to this disclosure provides a lot more light than the same fixture having 3 fluorescent bulbs. Thus it may be desirable depending on the location of the existing fixture 114 to be retrofitted or a new lighting fixture comprising the lighting system of this disclosure to dim the maximum amount of light provided by the fixture provided with the LED light assemblies 104.

Another advantage of the controller 108 and the power supply module 102 and the LED light assemblies 104 according to this disclosure is that they combine to have a substantially constant Power Factor or efficiency of at least or greater than 99%, even when the amount of light output by the LED assemblies 104 is dimmed. For example, the lighting system of this disclosure has been tested and shown to have a power factor or efficiency of the lamps that remains at least 95% when the lamp light output is dimmed due to ambient light sensing by sensors 106 and ambient light sensing circuit 142 or due to fixing the amount of light output by LED light bulbs or lamps 104 to be less than maximum with the multi-position switch 110.
