The rear lamp apparatus includes a light source configured to irradiate beams, a hologram lens configured to generate a specific image when the beams irradiated from the light source are incident thereto and a reflector disposed to position the beams of the light source incident thereto and reflect the beams irradiated from the light source to transmit the beams to the hologram lens. A shield is disposed between the light source and the hologram lens to block the beams irradiated from the light source to prevent the beams from being incident to the hologram lens. Accordingly, the rear lamp apparatus resolves distortion when a hologram image is formed and is advantageous in a layout by reducing a reproduction distance when a recording distance of the hologram image is increased. ## Claims ### Claim 1 A rear lamp apparatus of a vehicle, comprising: a light source configured to irradiate beams; a hologram lens configured to generate a specific image when the beams irradiated from the light source are incident thereto; a reflector disposed to position the beams of the light source incident thereto and configured to reflect the beams irradiated from the light source to transmit the beams to the hologram lens; and a shield disposed between the light source and the hologram lens to block the beams irradiated from the light source to prevent the beams from being be incident to the hologram lens, wherein the light source, the shield, and the hologram lens are disposed sequentially in a linear arrangement, and the reflector is disposed above or below the linear arrangement and is formed to transmit the beams to the hologram lens when the beams irradiated from the light source are reflected, and wherein the reflector is formed to transmit the beams at the same angle as a specific image recording angle of the hologram lens when the beams irradiated from the light source are reflected. ### Claim 2 (depends on 1) The rear lamp apparatus of a vehicle of claim 1, wherein the reflector is formed in a parabolic shape having the linear arrangement as an axis and having an installation position of the light source as a focus, and wherein the beams irradiated from the light source are transmitted in parallel with each other to the hologram lens when the beams are reflected. ### Claim 3 A rear lamp apparatus of a vehicle, comprising: a light source configured to irradiate beams; a hologram lens configured to generate a specific image when the beams irradiated from the light source are incident thereto; a reflector disposed to position the beams of the light source incident thereto and configured to reflect the beams irradiated from the light source to transmit the beams to the holograms lens; and a shield disposed between the light source and the hologram lens to block the beams irradiated from the light source to prevent the beams from being be incident to the hologram lens, wherein the shield is disposed to prevent interference with a path through which the beams irradiated from the light source are reflected from a first end portion of the reflector and are then incident to a first end portion of the hologram lens and a path through which the beams irradiated from the light source are reflected from a second end portion of the reflector and are then incident to a second end portion of the hologram lens. ### Claim 4 (depends on 1) The rear lamp apparatus of a vehicle of claim 1, wherein the second end portion of the shield is disposed above a first beam path through which the beams irradiated from the light source are reflected by the reflector and are then transmitted to the first end portion of the hologram lens. ### Claim 5 (depends on 1) The rear lamp apparatus of a vehicle of claim 1, wherein the second end portion of the shield is disposed below a second beam path through which the beams irradiated from the light source are directly transmitted to the second end portion of the hologram lens. ### Claim 6 (depends on 1) The rear lamp apparatus of a vehicle of claim 1, wherein the second end portion of the shield is disposed above a third beam path through which the beams irradiated from the light source are reflected by the reflector and are then transmitted to the second end portion of the hologram lens. ### Claim 7 (depends on 1) The rear lamp apparatus of a vehicle of claim 1, wherein the second end portion of the shield is disposed in a virtual triangle area formed by a first beam path through which the beams irradiated from the light source are reflected by the reflector and are then transmitted to a first end portion of the hologram lens, a second beam path through which the beams irradiated from the light source are directly transmitted to the second end portion of the hologram lens, and a third beam path through which the beams irradiated from the light source are reflected by the reflector and are then transmitted to the second end portion of the hologram lens. ### Claim 8 (depends on 1) The rear lamp apparatus of a vehicle of claim 1, wherein the shield has a blocking section that blocks the beams irradiated from the light source to prevent the beams from being directly incident to the hologram lens and a reflecting section bent from the blocking section and configured to reflect the beams reflected by the reflector to be incident to the hologram lens. ### Claim 9 (depends on 8) The rear lamp apparatus of a vehicle of claim 8, wherein the reflector has a first reflecting section configured to reflect the beams irradiated from the light source to be transmitted to the hologram lens and a second reflecting section configured to reflect the beams irradiated from the light source to be transmitted to the reflecting section. ### Claim 10 (depends on 8) The rear lamp apparatus of a vehicle of claim 8, wherein an angle formed by the blocking section and the hologram lens and an angle formed by the reflecting section and the hologram lens are less than an angle at which the beams irradiated from the light source and reflected by the reflector are incident to the hologram lens. ### Claim 11 (depends on 8) The rear lamp apparatus of a vehicle of claim 8, wherein the blocking sections and the reflecting sections of the shield are extended to be repeated multiple times in a length direction. ### Claim 12 (depends on 8) The rear lamp apparatus of a vehicle of claim 8, wherein the reflecting section forms a background image based on a shape that forms the reflecting section in an area of the shield.
