The LED 20 is a light emitted from the LED chip 21 by the hemispherical lens unit 22 is irradiated with a constant irradiation angle range (θ), usually 60 °, 45 °, 30 °, 20 °, etc. It is divided into having an irradiation angle range of θ, which is selected and used according to the lighting design.

The LED 20 is well known and will not be described in more detail, and the number of outputs and mountings will be understood to be variously modified according to the lighting design.

The side panel 11 of the metal panel member 10 covers the lower surface of the metal panel member 10 and is detachably coupled to the cover panel member 30 having transparency.

The cover panel member 30 is provided with mounting protrusions 30a inserted into the mounting grooves 12 in the longitudinal direction on both sides thereof, and the mounting protrusions 30a are inserted into the mounting grooves 12 to allow the metal panel to be inserted into the mounting grooves 12. It is attached to the member 10.

The mounting protrusions 30a may be coupled to each other by slidingly coupled through any one end of both ends of the mounting groove 12 in which both ends are open, and the cover is formed on the bottom surface of the metal panel member 10. By pushing the panel member 30 upward, the mounting groove 12 may be inserted and coupled by the elastic force of the side portion 11.

The cover panel member 30 is inserted between the side portions 11 on the upper surface, and the coupling portion 31 having the mounting protrusions 30a formed on both sides is protruded, and the amount of the coupling portion 31 is increased. A cover portion 32 is formed on the side to cover the lower surface of the side portion 11.

That is, the cover panel member 30 is mounted by coupling the mounting protrusions 30a into the mounting groove 12 in a state in which the coupling portion 31 is inserted between the side portions 11, and the cover portion ( 32 covers the lower surface of the side portion 11 to cover the metal panel member 10 from being exposed downward.

On the other hand, the cover panel member 30 has a lens insertion groove 33 is inserted into the lens portion 22 of the LED 20 on the upper surface.

The lens insertion groove 33 is formed in a hemispherical shape to correspond to the hemispherical lens portion 22, and is a portion for emitting light emitted through the lens portion 22 to the outside, the lower portion of the metal panel member 10 Since the lens unit 22 of the protruding LED 20 is inserted, the thickness of the metal panel member 10 can be made thinner.

In addition, the cover panel member 30 is formed with the lens insertion groove 33, the diffusion portion 34 for diffusing light emitted through the lens insertion groove 33 is formed on the upper portion, the diffusion portion at the bottom Covering the (34) and includes a transmission portion 35 for transmitting and emitting the diffused light.

In addition, a plurality of refractive grooves 37 are formed on the lower surface of the cover panel member 30 to refract light passing through the transmission part 35 to spread more evenly.

In addition, the cover panel member 30 is provided on the upper surface with a reflector 36 for reflecting light downward, refracted by the diffusion portion 34 and the refractive groove portion 37 is the upper portion of the cover panel member 30 By reflecting the light toward the lower side of the cover panel member 30, that is, the outside to allow the light emitted from the LED 20 to be emitted to the outside without loss as much as possible.

The reflector 36 is provided on the upper surface of the cover panel member 30 except for the lens insertion groove 33 into which the lens unit 22 of the LED 20 is inserted, thereby providing light of the LED 20 to the lens insertion groove. Only to emit through the 33 and to minimize the light lost between the lens insertion groove (33).

That is, as shown in FIG. 3, the light generated from the LED chip 21 of the LED 20 is irradiated with a constant irradiation angle range through the lens unit 22, and the light emitted through the lens unit 22 is emitted. It is evenly discharged to the outside through the diffusion part 34 and the transmission part 35 through the lens insertion groove 33.

In addition, the light is further diffused through the refraction groove 37 to be emitted more evenly to the outside, and is reflected through the reflector 36 between the lens insertion groove 33 is emitted to the outside to be emitted to the outside without loss.

On the other hand, both ends of the metal panel member 10 is provided with a cover fixing member 40 for fixing and releasing both ends of the cover panel member 30.

The cover fixing member 40 fixes and releases both ends of the cover panel member 30 to prevent the mounted cover panel member 30 from being separated during use or to fix the mounted cover panel member 30. Release the state to make it detachable.

The cover fixing member 40 is provided with a hinge portion 42 hinged to the side portion 11 of the metal panel member 10 on both sides, the groove cover portion blocking the open end of the mounting groove 12 (42) and a locking fixing portion (43) for hanging and fixing the end of the cover panel member (30).

In addition, both end portions of the cover panel member 30 are provided with a locking stepped portion 38 in which the locking fixing portion 43 is recessed.

In addition, any one of the engaging surface of the engaging step portion 38 and the locking fixing portion 43, the fixing projection (38a) protrudes, the other insertion surface projection insertion groove into which the fixing projection (38a) is inserted The cover panel member 30 is formed by a male and female coupling between the fixing protrusion 38a and the protrusion insertion groove 38b in a state in which the locking fixing portion 43 is seated on the locking step portion 38. Fix more firmly.

That is, in the state in which the cover panel member 30 is mounted on the metal panel member 10, each of the cover fixing members 40 provided on both sides of the metal panel member 10 is rotated to hold the locking part 43. ) Is positioned on the locking step 38 and the locking fixing part 43 is fixed to the both ends of the cover panel member 30, and the groove cover part 42 opens the open end of the mounting groove 12. By blocking, the cover panel member 30 is firmly fixed without flowing from the mounting groove 12.

In addition, when the cover fixing member 40 is fixed by walking both ends of the cover panel member 30 to release the locking state by rotating the locking fixing part 43 in the opposite direction, the mounting groove 12 is opened. The cover panel member 30 can be easily removed from the metal panel member 10 by separating the mounting protrusion 30a of the cover panel member 30 from the mounting groove 12 through both ends of the open mounting groove 12. It can be separated.

As described above, the present invention is composed of a metal panel member 10 and a cover panel member 30 covering the metal panel member 10 without a separate metal substrate, so that the maximum thickness of the lighting apparatus using the LED 20 can be achieved. It can be made thin.

In addition, the light emitted through the lens insertion groove 33 of the cover panel member 30 is diffused and refracted through the diffuser 34 and the refraction groove 37 to be emitted to the outside to illuminate a large area evenly. will be.

In addition, as shown in FIG. 5, the mounting bolt 50 coupled through the mounting hole of the metal panel member 10 is directly connected to the ceiling 1 to be easily installed.
