Abstract

The present disclosure relates to a rotary-type display apparatus using, for example, a light emitting diode (LED) which is a semiconductor light-emitting device, wherein the apparatus can be applied to technical fields related to display apparatuses. According to the present invention, a rotatory-type display apparatus using a light-emitting device comprises: a fixing part including a motor; a rotating part located on the fixing part and rotated by the motor; and a light source module which includes at least two rod-shaped panels coupled to the rotating part and arranged radially, and light-emitting device arrays respectively disposed on the panels in the longitudinal direction, wherein the height of the at least two panels from the rotating part may be different.

First claim

What is claimed is:

1. A rotary-type display device comprising:
a fixed portion including a motor;
a rotary portion positioned on the fixed portion and configured to be rotated by the motor;
a light source module including at least two elongated panels coupled to and extending radially from the rotary portion, and
height adjusters configured to position the at least two elongated panels of the light source module at different heights,
wherein each of the at least two elongated panels comprises a light-emitting element array longitudinally disposed along the panel,
wherein the at least two elongated panels are positioned at different heights.

2. The rotary-type display device of claim 1 , wherein each of the at least two panels comprises a coupler coupled to the rotary portion.

3. The rotary-type display device of claim 2 , wherein each of the at least two panels extends from a corresponding coupler.

4. The rotary-type display device of claim 2 , wherein each coupler has an edge oriented parallel to a light-emitting element array of an adjacent panel.

5. The rotary-type display device of claim 4 , wherein the edge of the coupler does not interfere with the light-emitting element array of the adjacent panel.

6. The rotary-type display device of claim 2 , wherein the rotary portion comprises an upper frame to which the height adjuster is coupled.

7. The rotary-type display device of claim 6 , wherein the upper frame has at least one coupling hole with which the light source module is coupled.
