No additional decorative trim elements or baffles are required and the diffuser lens both illuminates and covers the ceiling aperture to provide a smooth illuminated unitary appearance. This outermost diffuser lens is illuminated from above by an illumination system which includes a ring support on which the LEDs may be mounted, along with an optical stack which collects light output from the LEDs and both illuminates and redirects the light through the outermost diffuser lens. This outermost diffuser lens provides appearance of smooth continuous illumination output along its entire surface and while also covering aperture edges formed in the ceiling for the recessed fixture. ## Claims ### Claim 1 A trimless recess light fixture, comprising: an outer lens having a first diameter;
