Disclosed herein is a lighting fixture in which a threadless fit is achieved between a lens cover and a housing. The lighting fixture comprises a housing, a circuit board and a lens cover. The housing and the lens cover are arranged on opposite sides of the circuit board. The housing comprises a first slot. The lens cover comprises a first tab configured to fit into the first slot by a threadless fit, thereby securing the lens cover to the housing. Compared with lighting fixtures in the prior art, the lighting fixture of the present disclosure can save process steps, simplify manufacturing process, reduce manufacturing cost, and improve heat dissipation and light distribution efficiency.

Lighting fixture with threadless fit

An LED assembly includes a substrate, an LED module mounted on the substrate, and a lens plate disposed on the substrate. The lens plate has a lens portion disposed atop the LED module and defining a space between an inner surface of the lens portion and the LED module. A filler material having a refractive index greater than air fills the space between the LED module and the inner surface of the lens portion. The LED module includes a chip holder mounted on the substrate, a red LED chip mounted on the chip holder, and an optical encapsulant covering the top surface of the LED chip. The LED module is a plastic leaded chip carrier package. The refractive index of the filler material preferably differs from the refractive index of the optical encapsulant by at most ±0.3.
