A downlight having direct-press assembling mechanism includes a housing, a light source board, a light cover and a plurality of spring fastening members. The housing has a cylindrical body, an opening disposed at one end of the cylindrical body and a plurality of fixing portions disposed on the outer wall of the cylindrical body. The light source board is disposed inside the cylindrical body. The light cover is disposed on the cylindrical body to cover the opening. The two ends of each of the spring fastening members is provided with a supporting portion and a locking portion respectively. The supporting portion is combined with the fixing portion corresponding thereto after a force is applied to directly press the supporting portion toward the fixing portion corresponding thereto. The above structure can reduce the difficulty of the assembling process and increase the work efficiency in order to decrease the manpower cost.

The specification and drawings present a new light accessory holder, comprising only one part, for placing and interchanging multiple optical accessories in a lighting fixture near/in front of a light sources such as LEDs. The holder can use multiple notched springs (e.g., three) to push accessories forward and holds them in a desired position. The may be removed from the lighting fixture, so the user can load into the holder whatever accessories are needed, and then return the re-loaded holder into the light fixture. Accessories may include but are not limited to diffusers, glass components (optical filers), Hexcel Louvers, snoots, or other objects that are intended to alter the color or shape of a light source.

A light emitting diode (LED) lighting system includes an enclosure, a trim, and at least one attachment mechanism. The enclosure can include at least one heat-generating device and an enclosure collar, where the enclosure is made of a first thermally conductive material. The trim can include a trim collar and at least one wall that defines a passage, where the trim collar abuts the enclosure collar, and where the passage has a reflector and a LED is disposed therein. The least one attachment mechanism can removably couple the trim collar to the enclosure collar, where the at least one attachment mechanism includes a back plate that is mechanically coupled to an upper flange and a lower flange, where the upper flange contacts the enclosure collar and the lower flange contacts the trim collar.

An automatic lamp installation mechanism includes a support element having one end of rotatably connected to a side of a fixing base; an elastic element arranged between the support element and the fixing base, a fixing element provided on the support element and including a first catch element; and a limiting element provided on the side of the fixing base and having a triggering element and a second catch element, wherein the triggering element is located apart from the fixing base.

A light fixture includes a light module and a trim assembly, where the trim assembly is removably coupled to the light module. The light module includes a module assembly that accommodates a light source. Further, the light module includes an additional heat sink that is optionally coupled to the module assembly. The trim assembly includes a lens, a reflector, and a trim. In particular, the reflector is coupled to the trim by inserting tabs extending downwards and substantially perpendicular from a collar of the reflector into through slots on a top collar of the trim such that the lens is securely retained and disposed in between the reflector and the trim.

An optical attachment feature of a light-emitting diode (LED) lighting system includes an enclosure, a trim, a reflector, and a diffuser. The enclosure can include an enclosure wall forming a cavity and an enclosure collar having a first profile. The trim can include a trim collar that abuts to the enclosure collar, wherein the trim collar has a second profile. The reflector can include an outer surface, an inner surface having reflective material disposed thereon, and a reflector collar having a first optical attachment mechanism. The diffuser can include a diffuser collar, where the diffuser collar can include a second optical attachment mechanism and a third optical attachment mechanism, where the second optical attachment mechanism can couple to the first optical attachment mechanism, and where the third optical attachment mechanism is disposed within a feature formed by the first profile and the second profile when the enclosure collar is mechanically coupled to the trim collar.

An illuminant with at least two LEDs mounted on mutually opposite sides of a support plate and a reflection surface formed as a concave mirror, in which concave mirror the LEDs are arranged, wherein a housing part of the illuminant made of a transparent housing material is provided, which housing part at the same time forms an in relation to the main propagation direction lateral external surface of the illuminant and supports a reflecting layer forming the reflection surface at an internal surface opposite to the external surface.

A lighting device may be provided according to the embodiment of the present invention. The lighting device according to the embodiment of the present invention includes: a light source which includes a substrate including a top surface and a bottom surface, a plurality of light emitting devices disposed in a central portion of the bottom surface of the substrate, and an input/output portion disposed in an edge portion of the bottom surface of the substrate and electrically connected to a wire; and a body which is coupled to the substrate of the light source and includes an opening through which light from the plurality of light emitting devices of the light source passes. The body includes an inner surface which defines the opening. The body includes a cover portion which is disposed on the inner surface of the body and covers the input/output portion of the light source and the wire.

An LED lamp includes a heat dissipation lamp holder; an LED lamp panel mounted on a front side of the heat dissipation lamp holder; a light transmitting panel covering the LED lamp panel; and a locking assembly including: an engaging member movably mounted on the heat dissipation lamp holder; a button hinged to the heat dissipation lamp holder; and a first elastic resetting member connected to the button and abutting against the heat dissipation lamp holder. The button is provided with a connecting portion engaged with the engaging member to enable the engaging member to lock the light transmitting panel, when the button is pressed, the first elastic resetting member is compressed, and the connecting portion is disengaged from the engaging member, so that the engaging member unlocks the light transmitting panel.
