The present invention discloses a side-emitting LED panel lamp, where the side-emitting LED panel lamp includes a frame, a light-emitting element, a driving power supply, a backboard, a pressing bar, a light guide plate, and a diffusion plate; the light-emitting element, the driving power supply, and the backboard are disposed on a lower surface of the frame; the pressing bar is disposed around the backboard and covers the driving power supply; the driving power supply is electrically connected to the light-emitting element; the light guide plate is disposed on a lower surface of the backboard; the light guide plate is flush with the light-emitting element; and the diffusion plate is disposed on a lower surface of the light guide plate. In the present invention, all the components are integrally assembled. When used, the side-emitting LED panel lamp can be directly connected to a mains power supply, so as to avoid lamp damage caused because the light-emitting element does not match the driving power supply due to secondary adjustment, therefore facilitating a direct operation of a user.

The solid content contains a resin component (A) and a filler (B). The resin component (A) includes at least one of a fluorine-containing copolymer (a1) or a silicon-containing copolymer (a2). The fluorine-containing copolymer (a1) includes a fluorine-containing segment and an acrylic segment containing no fluorine or silicon. The silicon-containing copolymer (a2) includes a silicon-containing segment and an acrylic segment containing no fluorine or silicon. The filler (B) has a mean particle size falling within a range from 10 nm to 200 nm.

A lighting device includes an optical assembly and an obstruction sensor configured to receive radiation reflected by the optical assembly. The lighting device also includes a processor that is configured to receive information corresponding to the radiation reflected by the optical assembly from the obstruction sensor, and compare the received information to a plurality of known reflection patterns associated with one or more properties of the optical assembly to determine a property of the optical assembly.

The present invention provides an LED module that can prevent breakage of an LED chip due to pulse lighting for a flash when the LED module is used in a flashing lamp. An LED module (10) for flashing lamp includes: an LED substrate (13); plural LEDs (12); and plural resin layers (11). In the LED module (10), the LEDs (12) are mounted on a mounting surface of the LED substrate (13). Each resin layer (11) is stacked on a surface of each LED (12) opposite to the LED substrate (13). Adjacent resin layers (11) stacked on the LEDs (12) are separated from each other.

A luminaire includes a light emitting diode module, a driver housing, and a hollow connector that connects the driver housing and the light emitting diode module. The driver housing includes a rotatable cap and a driver that provides power to the light emitting diode module. The rotatable cap permits rotation of the hollow connector and the light emitting diode module in order to direct the light from the light emitting diode module in a desired direction. The light emitting diode module includes a plurality of optics wherein each optic covers at least one light emitting diode and at least one vent adjacent to each optic.
