A retrofit light mount has a pivot rack configured to install to a T-bar frame. The pivot rack is elongated and has a U shape when viewed from above. A lamp has an LED box and a reflector. The lamp has a pivot end and a distal end. A pair of spade hooks are formed on the pivot end, including a first spade hook and a second spade hook. An inside rack vertical portion is formed on the pivot rack. The inside rack vertical portion is a vertically oriented panel. A first notch and a second notch are formed on the inside rack vertical portion. The first notch is configured to receive the first spade hook, and the second notch is configured to receive the second spade hook.

A laser projecting device and a light-combining lens are provided. The light-combining lens is a one-piece structure, and has a difference of refractive indexes less than 0.2. The light-combining lens includes collimation surfaces, reflection surfaces, and a light emergent surface. Each collimation surface defines a collimation path inside the light-combining lens. The reflection surfaces respectively located at the collimation paths are parallel to each other and arranged along an arrangement direction. The light emergent surface is located at the arrangement direction. Each reflection surface and the corresponding collimation path have an acute angle therebetween to define a reflection path. The reflection paths are overlapped in the light-combining lens to define a light-combining path. The light combining path passes through at least one of the reflection surfaces that allows light to pass therethrough along the light-combining path, and passes through the light-combining lens from the light emergent surface.

A light fixture includes a housing that defines a housing chamber having a housing opening. The light fixture is configured to emit light through the housing opening. The light fixture also includes a waveguide supported within the housing chamber and over the housing opening. The light fixture may include a backing plate supported within the housing chamber and biasing the waveguide towards the housing opening. The light fixture may include a transition cover with a cover body extending from a first portion of the waveguide to the housing opening and a light dam extending from the cover body towards a second portion of the waveguide.

A modular lighting fixture that is capable of receiving interchangeable functional modules includes a body having a main portion and a second portion. The main portion has a hollow interior defining an interior space extending in a longitudinal direction from a first open end of the main portion to a second end of the main portion. The second portion is provided at the first end and extends outwardly in a transverse direction, wherein the interior space is configured to receive and retain a functional module configured to provide non-light emitting function. A light emitting means is provided on the second portion of the body and configured to emit light.

A backlight module includes a carrying member, a light source, a light guide plate, a fixing frame and an outer component. The light source is disposed on the carrying member. The light guide plate is disposed on the carrying member, in which a light-incident surface of the light guide plate is disposed adjacent to the light source. The fixing frame fixed on a bottom portion of the carrying member along a first direction. The outer component is fixed on the fixing frame along a second direction.

The present invention is directed to a light fixture assembly and a releasable fastener for use with a light fixture assembly. The light fixture assembly includes: a first light fixture component; a second light fixture component that includes an engagement surface and an aperture; and a releasable fastener configured to extend through the aperture and engage the engagement surface when in the locked position to releasably secure the first and second light fixture components together.

A lighting device comprises a base (7), a light aggregate (3), and a lens member (1) covering the light aggregate (3). The base (7) and the lens member (1) comprise mounting holes (27, 25), the mounting holes (25) of the lens member (1) being positioned along the periphery (1A) of the lens member (1). Mounting holes (25, 27) of the lens member (1) and the base (7) are aligned, and mounting elements (11A, 11B) are extending and fixed in said mounting holes (25, 27) thereby fixing the lens member (1) to the base (7). Each of the mounting elements (11A, 11B) at least along half of the periphery (1A) of the lens member (1) are yielding elements relative to the base (7) and the lens member (1). The mounting elements (11A, 11B) have a lower Young's modulus than the base (7) and the lens member (1).

The present application provides a collapse preventing lamp, comprising a lamp panel and a lamp frame, wherein the lamp panel as a light source is installed in the lamp frame, and wherein a gap is defined between at least one side edge of the lamp panel and an edge of the lamp frame; and a baffle for shielding the gap is provided which is overlapped on the lamp frame, and the baffle is provided with an anti-collapse member for supporting a corresponding side edge of the lamp panel.
