Definitions

• the present disclosure relates to light fixtures, and more particularly, to a light fixture that provides forces to moveable devices therein.
• a light fixture assembly often has a heat sink.
• Springs are often used on the heat sink to generate resistance to hold the components in place. Often times, multiple springs or other devices are used which must operate simultaneously and equally. Such springs and devices do not easily allow for horizontal travel of the heat sink and therefore the heat sink may be moved at an angle which is undesirable.
• Another issue with light fixture assemblies is that designers desire smaller and smaller openings for the light. In some cases, designers would like the ceiling surface to be continuous and the light without trim. However, it is often desirable to provide access within the light fixture assembly housing to replace various components such as the LEDs, optics and drivers. Accessing the components is dependent on the removal of the baffle because the baffle apertures have become smaller.
