Abstract: A skylight LED lighting system is described. The system utilizes LED lights attached to or near a skylight in order to provide a user with the ability to increase the amount of light being directed into an area. The system can utilize a LED controller to allow the user to control the light output intensity. The LED controller provides a smooth range of changing brightness levels. The system can utilize one or more solar cells and batteries to power the LED lights. The system can be controlled via a radio frequency remote control. Additionally, the system can utilize a flexible, skylight-shaped installation housing that can be inserted into the skylight under compression. When the compression is released, the ring expands to press against the inside of the skylight and holds the skylight LED lighting system in place.

Abstract: A LED controller that allows the user to control the output intensity of one or more LED lights is disclosed. The intensity levels or brightness of the LED lights are not limited to 3, 4 or even 10 levels of light output; instead, the LED controller provides what appears to the human eye as a smooth range of changing brightness levels depending on the needs the user.

Abstract: A LED louvers and lighting system is described. The system can utilize interchangeable LED light assemblies placed within LED light modules. The light output from the light modules can be directed and diffused via a selection of louvers. A LED controller can be utilized to allow a user to control the light output intensity from the light modules. The LED controller provides a smooth range of changing brightness levels. The system can be controlled via a wired switch and/or a radio frequency remote control. Additionally, the LED light modules are daisy chainable and can utilize low-voltage wiring for ease of installation.

Abstract: A cooling apparatus (27) for a locomotive dynamic brake resistor grid stack (22) including a flow directing diffuser (24). The flow directing diffuser includes at least one turning vane member (26) disposed at an angle to the flow stream axis for directing a portion of the cooling air from a high velocity area of the air stream into a lower velocity area of the air stream. The flow directing diffuser may include an annular ring-shaped turning vane member (28) for directing high velocity air into a center low velocity area. The flow directing diffuser may further include a V-shaped turning vane member (32) associated with each corner (34) of the surrounding duct (36) for directing high velocity air into each corner low velocity area. Air is supplied to the duct 36 housing the flow directing diffuser by a mixed flow fan (54).
