Lighting device and vehicular lamp comprising same

A lighting device comprising:

• a shielding module including an opening area in an upper portion of the shielding module and a shielding area extending from the opening area, and including a lower surface portion, side surface portions extending upward from the lower surface portion, and bent portions bent from the side surface portions and defining the opening area;
• light source modules arranged between the lower surface portion and the bent portions of the shielding module;
• a first light guide member arranged on light emitting surfaces of the light source modules inside the shielding module;
• and
• a lens module arranged on the first light guide member such that a lower surface of the lens module is in contact with an upper surface of the first light guide member and a part of an upper surface of the lens module is in contact with inner surfaces of the bent portions,
• wherein light emitting directions of light emitting elements inside the light source modules form an inclination angle with the light emitting surfaces of the light source modules, the inclination angle being defined as an angle between virtual vertical lines W2 passing through centers of the light emitting elements and virtual extending lines W1 of the light emitting surfaces of the light source modules,
• wherein each of the light source modules includes:
• a light source including a light emitting element;
• a printed circuit board on which the one or more light sources are mounted;
• a second light guide member arranged on the printed circuit board;
• and
• a diffusive member arranged on the second light guide member, and
• wherein an optical pattern is disposed between transparent optical sheets between the second light guide member and the diffusive member.

A vehicular lamp comprising a lighting device including:

• a shielding module including an opening area thereon and a shielding area extending from the opening area, the shielding module including a lower surface portion, side surface portions extending upward from the lower surface portion, and bent portions bent from the side surface portions and defining the opening area;
• a light source module disposed inside the shielding module and including a second light guide member in which a light emitting element is embedded;
• a first light guide member disposed inside the shielding module and being in contact with a light emitting surface of the light source module;
• and
• a lens arranged on the first light guide member such that a lower surface of the lens is in contact with an upper surface of the first light guide member,
• wherein an inclination angle is formed between a light emitting direction of the light emitting element and the light emitting surface of the light source module,
• wherein a length of each bent portion is longer than a transverse width of the light source module,
• wherein a transverse width of the lens is longer than a transverse width of the first light guide member, and the transverse width of the lens is longer than a transverse width of the opening area,
• wherein the lighting device comprises a central region within imaginary vertical lines extending downwardly, in a vertical direction parallel to the side surface portions of the shielding member, from a perimeter of the opening area of the shielding module towards the lower surface portion of the shielding module, the central region having at least a portion of the first light guide member and at least a portion of the lens disposed therein, and
• wherein the light source module is disposed entirely below the bent portions, and the light source module is absent from the central region of the lighting device.
