Abstract

Disclosed is a lighting device. The lighting device includes: a housing; a coupling member being coupled to the housing and having an insertion groove; at least one reflector disposed within the housing and having a parabolic surface; and a power supply unit being disposed in a space formed between the reflector and the corner of the housing, and providing at least one of electric power and a driving signal to a light source unit coupled to the insertion groove, wherein at least one first groove is formed on the wall surface of the coupling member, wherein at least one second groove is formed on the wall surface of the housing, wherein a first side of the reflector is inserted and coupled to the second groove, and wherein a second side of the reflector is inserted and coupled to the first groove.

Claims

1. A lighting device comprising:

a housing;

a coupling member being coupled to the housing and having an insertion groove;

at least one reflector disposed within the housing and having a parabolic type surface; and

a power supply unit being disposed in a space formed between the reflector and the corner of the housing, and providing at least one of electric power and a driving signal to a light source unit coupled to the insertion groove,

wherein at least one first groove is formed on a wall surface of the coupling member,

wherein at least one second groove is formed on a wall surface of the housing,

wherein a first side of the reflector is inserted into the second groove and

wherein a second side of the reflector is inserted into the first groove.

2. A lighting device comprising:

a housing;

a coupling member being coupled to the housing and having an insertion groove;

at least one reflector disposed within the housing and having a parabolic type surface;

a light source unit having an upper part and a lower part; and

a power supply unit being disposed in a space formed between the reflector and the corner of the housing, and providing at least one of electric power and a driving signal to a light source unit,

wherein the upper part of the light source unit is coupled to the coupling member and light emitted from the lower part of the light source unit emits to the reflector,

wherein at least one first groove is formed on a wall surface of the coupling member,

wherein at least one second groove is formed on a wall surface of the housing,

wherein a first side of the reflector is inserted into the second groove, and

wherein a second side of the reflector is inserted into the first groove.

3. The lighting device of claim 2, wherein the light source unit comprises:

a first body including a first inclined part toward the reflector;

a second body including a second inclined part toward the reflector;

a middle body formed between the first body and the second body; and

a plurality of light emitting diodes which are disposed on the first inclined part and the second inclined part respectively.
