Lighting module and lighting device provided with 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.

Lighting apparatus and automotive lamp comprising same

The present invention provides a light source module for a vehicle comprising: a plate-like heat sink; substrates provided on both sides of the heat sink, respectively; light emitting devices provided on the substrates, respectively; a hole for transmitting light emitted from the light emitting devices; and a pair of bases coupled to the outside of the substrates, wherein the light emitting device includes a first light emitting device and a second light emitting device which are arranged diagonally, and a blocking member is disposed at a lower end of the second light emitting device. As such, it is possible to increase the heat dissipation efficiency by increasing the contact between the heat sink and the substrates.

Light source module for vehicle

Provided is a lighting unit for a vehicle capable of implementing surface light emission from a single light emitting surface. The light unit can function to implement a light emitting region in which at least two light colors are displayed or different light colors are implemented, or to locally emitting light.

Lighting unit for vehicle

The present invention relates to a structure of an edge-type back light unit, particularly to a structure comprising a light source receiving part, which receives a light source such as LED formed to the central direction of an optical plate at one side or the other side of the optical plate. The present invention has excellent optical property and has an effect of wide application to various LCDs because it comprises a light source receiving part, which can install a printed circuit board mounting the light source such as LED to an embedded form in an edge-type back light unit.

Back light unit

A light unit is provided. The light unit includes a PCB mounted with a plurality of LEDs, and a light guide member having a plurality of reception grooves piercing therethrough and receiving the LEDs, wherein the light guide member includes one surface and the other surface opposite to the one surface, and the one surface of the light guide member is further coated with the resin material. The reception grooves are formed in the light guide member and are filled with a fluid resin material, thus preventing the damage to the LED caused by the difference between the thermal expansion rates of the components such as the light guide member, the reflection film and the PCB.

Light unit

Disclosed is a light unit. The light unit includes a printed circuit board formed thereon with a plurality of LEDs and a light guide member having receiving holes to receive the LEDs. At least one round part having a predetermined curvature is formed at an edge defined in an intersection between an upper surface and an inner surface of the receiving hole. Since the round part is formed at the edge in the receiving hole receiving the LED at the portion of the light guide member, the light distribution is improved so that the light efficiency is increased.

Light unit having light guide member with receiving holes with round part

The present invention provides a light unit, comprising a printed circuit board equipped with a plurality of LEDs; and a light guide member equipped with mounting grooves to house the LEDs. It is preferred that the light guide member comprises one surface and another surface facing the one surface; a first density pattern area and a second density pattern area having higher density than that of the first density pattern area are formed in the one surface; and the second density pattern is disposed in an area closer to the light emitting surface of the LED than the first density pattern area. According to the present invention, hot spots can be removed by forming high density optical patterns on the upper surface of a light guide member and diffusing the light of LEDs; meanwhile, the transmission range of light can be extended and light extraction efficiency can be improved by disposing low density optical patterns in adjacent areas.
