[0033] When a part in this specification is said to be connected to another part, this includes not only direct connections but also connections with other elements intervening. Furthermore, when a part is said to include a component, this does not exclude other components, unless otherwise specifically stated, but rather implies the inclusion of additional components.

[0034] While terms such as "first," "second," and "third" may be used herein to describe various components, these components are not limited by these terms. These terms are used to distinguish one component from another. For example, without departing from the scope of the present invention, a first component could be referred to as a "second" or "third" component, and similarly, a "second" or "third" component could be referred to interchangeably.

[0035] The lighting device of the present invention includes a main body coupled to a ceiling and an indirect lighting unit coupled to the main body. The indirect lighting unit includes an indirect light, a main frame, a first diffusion unit, and a second diffusion unit. The indirect lighting emits light. The main frame is arranged to block light of the indirect lighting from propagating straight from the indirect lighting to the outside of the lighting device. The first diffusion unit is arranged so as not to be exposed to the outside of the lighting device and diffuses the light of the indirect lighting. The second diffusion unit is configured so that at least a portion thereof is arranged between the first diffusion unit and the main frame and at least a portion thereof is exposed to the outside of the lighting device, thereby transmitting the light of the indirect lighting to the outside of the lighting device. Since the first diffusion unit is arranged so as not to be exposed to the outside, light does not propagate straight from the first diffusion unit to the illuminated space. Instead, light passing through the first diffusion unit is reflected by the main frame and propagates to the outside of the lighting device through the second diffusion unit.

[0036] Hereinafter, a lighting device according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an exploded perspective view of a lighting device according to an embodiment of the present invention.
