Total Claims: 8
Claim 1
Independent Claim
157 words
Elongated one-piece plastic lighting panel trim elements for attachment to each of the outer marginal edges of a thick cellular lighting panel to facilitate mounting the lighting panel in a ceiling suspended lighting panel frame without routing the marginal edges of the lighting panel, said lighting panel trim elements being peripherally mounted on each outer marginal edge of the lighting panel, each lighting panel trim element having a throat section for receiving the top, side and bottom marginal edges of the thick cellular lighting panel, each lighting panel trim element also having a horizontal wall section integral and in direct line with the throat bottom wall section and extending outwardly from the lighting panel for mounting the lighting panel relative to the ceiling suspended lighting panel frame, and said lighting panel trim elements each also having a flexible top wall lip portion for securing the lighting panel within the throat sections of the lighting panel trim elements.
