An LED lamp for illuminating a surface under a flat angle in linear lighting applications such as cove lighting and wall washing is provided. It produces a uniform intensity distribution and a uniform color output throughout the beam pattern of the light beam produced by a multi-color LED light source. The lamp comprises a body of an extruded profile. The body comprises at least one section with a mirrored surface and at least a lens section which allows exiting of light from the body. At least one LED preferably having a LED lens is provided at the inner side of the body. This combination of optical systems results in an asymmetric beam pattern from the source.

A lighting unit body comprises: a light source; and shaped-members, in which a housing portion in which the light source is disposed, reflective surfaces for reflecting light from the light source, and an emission outlet for emitting the light from the reflective surfaces are respectively formed in the longitudinal direction. When a position at which the emission outlet is disposed is defined as forward and a direction orthogonal to the longitudinal direction is defined as a front-to-rear direction, and a direction orthogonal both to the longitudinal direction and the front-to-rear direction is defined as a left-to-right direction, then the emission outlet is formed in a front portion of the reflective surfaces, and the housing portion is formed in a rear portion of the reflective surfaces directed obliquely rearward at a predefined inclined angle on one of left or right side. The predefined inclined angle is an angle that inhibits visual observation of the light source from the front of the emission outlet, and the left-to-right direction position at which the light source is disposed is included in the left-to-right direction position at which the emission outlet is located.

Electrical lighting housings and heat sinks constructed of pitch-based carbon fiber that act as heat sinks for light emitting diode (“LED”/“LEDs”) lights. Greater heat dissipation cools the LED lights and power suppling components, which in turns increases the life span of these components, without the need for active cooling. Due to the improved physical strength of pitch-based carbon fiber over aluminum and other typical heat sink and housing materials, the wall thickness of a housing can be decreased when using pitch-based carbon fiber which can further aid in thermal transfer.

An LED tube lamp comprises a glass tube; a diffusive layer covered on the glass tube; two end caps coupled to the glass tube; a light strip attached inside the glass tube and comprises a first set of connecting pads; a plurality of light sources; and a power supply module comprises a circuit board, a rectifying circuit, and a filtering circuit. The circuit board comprises a first surface, a second surface opposite to and substantially parallel to the first surface and the axial direction of the glass tube, and a second set of connecting pads arranged on one of the surfaces. The light strip, a portion of the circuit board being stacked with the light strip, and at least one set of the connecting pads is disposed between the light strip and the portion of the circuit board are stacked sequentially in a radial direction of the glass tube.

A high-efficiency linear light source focused strip lamp has a strip lamp frame, a strip lamp plate provided on the strip lamp frame, a condensing lens arranged above the light emitting direction of the light-emitting chip, and a strip lamp cover connected to the strip lamp frame and located above the condensing lens; the strip lamp cover is provided with a convex lens array that visually stretches the light-emitting chip along a length direction. The high-efficiency linear light source focused strip lamp performs light distribution through the concentrating lens in the vertical length direction, and achieves high-efficiency sweeping function, and in the longitudinal direction, the light-emitting chip is performed visually stretching by the convex lens arrays on the strip lamp cover, thus achieving the effect of the line light source, solves the original glare problem without affecting the efficiency.

Disclosed herein is an optical assembly and a luminaire with extreme cutoff beam control optics. The optical assembly includes a base, a plurality of lenses disposed on the base and spaced from each other, a plurality of light emitting diodes (LED), and a reflector having a curved surface (e.g., concave shape, parabolic shape, etc.) disposed adjacent to at least one of the plurality of LEDs.
