LIGHT-EMITTING ELEMENT PACKAGE AND LIGHTING DEVICE HAVING SAME
The lighting device disclosed in the embodiment of the invention includes a light emitting device package including a plurality of lead frames, a body coupled to the plurality of lead frames, a cavity in which a front side portion of the body is opened, and a light emitting chip disposed on a first lead frame that is any one of the plurality of lead frames; a circuit board on which the light emitting device package is disposed and having a first pad portion; a resin layer covering the light emitting device package on the circuit board; a reflective member disposed between the resin layer and the circuit board and into which a lower portion of the light emitting device package is inserted; and a light blocking portion overlapping the light emitting device package in a vertical direction on the resin layer, wherein the first lead frame may include a first frame disposed at a bottom of the cavity and is bent from the first frame to a lower surface of the body, and a first bonding portion coupled to the first pad portion of the circuit board, and the first bonding portion may protrude from the lower surface of the body toward a rear side portion of the body more than the rear side portion of the body.
Vehicle lamp
A vehicle lamp suppressing design deterioration due to moire is provided. The vehicle lamp includes: a first plate material including a plurality of first light transmissive areas transmitting light therethrough and a first light non-transmissive area positioned between the plurality of first light transmissive areas and not transmitting light therethrough; a second plate material including a plurality of second light transmissive areas transmitting light therethrough and a second light non-transmissive area positioned between the plurality of second light transmissive areas and not transmitting light therethrough, the second plate material being layered on the first plate material; and a light source that emits light via the plurality of first light transmissive areas of the first plate material and the plurality of second light transmissive areas of the second plate material, where the plurality of second light transmissive areas are larger, in acreage, than the plurality of first light transmissive areas.
LIGHTING APPARATUS AND AUTOMOTIVE LAMP COMPRISING SAME
The lighting device disclosed in the embodiment of the invention includes a substrate; a plurality of light emitting devices disposed on the substrate and emitting light in at least a first direction; a resin layer sealing the plurality of light emitting devices; and an optical member disposed on the resin layer, wherein the resin layer may include a first light blocking portion integrally formed with the resin layer and having a transmittance lower than that of the resin layer on an emission-side region of each of the plurality of light emitting devices.
HOMOGENOUS LED VEHICLE LAMP
A homogenous light-emitting diode (LED) lamp for an automotive vehicle is provided that includes multiple LEDs configured as a LED array and a diffusion sheet. The diffusion sheet has a curvature aligned with the LED array for smoothing and bending light emitted by the LEDs for the purpose of creating a lighting appearance substantially lacking hotspots. An automotive vehicle lamp for producing homogenous light is provided. The vehicle lamp includes multiple LEDs each positioned a first distance apart from one another to form an array of LEDs, and a diffusion sheet positioned a second distance from the array of LEDs for smoothing light emitted from the array of LEDs. The first distance and the second distance are arranged for the purpose of providing a substantially homogenous light output from the vehicle lamp when viewed through the diffusion sheet.
LENS WITH ELONGATED RADIATION PATTERN
An elongated lens (300) is formed with a trough (310) along the long axis on the light emitting surface of the lens. The elongated lens (300) may include a curved wall (325) about its perimeter, and a smooth transition (317) between the curved wall (325) and the trough (310). The trough (310) may include a concave shape along both the long axis and the short axis, although the radius of curvature of the concave shape may differ between the long and short axes. The eccentricity of the illumination pattern may be controlled by the size of the trough (310) and these radii of curvature.
Through-Type Lamp and Vehicle
A through-type lamp includes a housing and an outer surface cover. The housing is provided with a slot extending along the extension direction Y of the housing. The outer surface cover is provided with a protrusion extending in the extension direction of the outer surface cover. The protrusion is clamped in the slot, so that the housing and the outer surface cover (6) define a light chamber. A vehicle includes the through-type lamp.
Lighting apparatus and automotive lamp comprising same
