An exemplary embodiment of the present invention will be described as follows.

The LED module 30 configured in the lamp body chassis 20 by installing the lamp body chassis 20 on the reflective surface 12 and the outer frame 11, the center protruding high and inclined toward the outer frame 11 side. ) to project the light source from which the light emitting lamp 31 is generated on the reflective surface 12 through the lens 40. .

As described above, the present invention used for indirectly irradiated LED ceiling lamps using light reflection has a length suitable for installation on the inner circumferential surface of the outer rim of the luminaire 10 to be installed and used in the lamp body chassis 20 and the lens 40. and the LED module 30 is cut.

When the cutting is completed in this way, the LED module 30 is inserted into the module coupling part 21 of the lamp body chassis 20 and combined.

In this way, when the coupling of the LED module 30 is completed, the lens 45 is inserted into the lens coupling part 22 formed in the lamp body chassis 20 and coupled.

At this time, the light emitting lamp 31 of the LED module 30 is inserted into the light emitting lamp receiving groove 45 of the lens 40 and positioned. At this time, the protruding end of the convex lens part 46 of the lens 40 and the LED module 30 Since the space of the rear end of the engaging blade 43 to be in close contact is 2.1 mm, a space is generated.

Therefore, even if the lens 40 causes thermal expansion by the heat source generated from the light emitting lamp 31 during use, no external force acts on the light emitting lamp 31 and thus is protected.

When the lens 45 is inserted and coupled to the lens coupling part 22 formed in the lamp body chassis 20 as described above, the lamp body chassis 20 is in close contact with one side of the lens 40 and the other side is The lamp body chassis 20 maintains the separated state, and the LED module 30 is also in a free state.

In such a state, when the wedge piece 29 is coupled to the wedge groove 26 of the lamp body chassis 20, which is a lens fixing means, the wedge groove 26 opens and the bending part 24 is bent, so that the pressing jaw 25 Press the coupling blade 43 of the lens 40 toward the LED module 30 to fix the rear surface of the LED module 30 in close contact with the module coupling part 21 of the lamp body chassis 20, and then the lamp body chassis 20 The contact surface 23 of the lens is in close contact with the side surface 42 of the lens 40 to firmly fix the lens.

In the present invention, which is configured by combining the LED module 30 and the lens 40 as described above, the lamp body chassis 20 is configured to face the outer frame 11 of the lamp 10, or a square outer frame 11 ) to be installed in each.

At this time, when the inclination of the reflective surface 12 of the luminaire 10 is 14° in the horizontal direction, it is ideal that the light transmitting surface 41 of the lens 40 opposite to this has an inclination of 13° in the vertical direction.

Here, as another configuration of the present invention, when the lens constituting means constitutes a separate push bar 50 separated from the lamp body chassis 20 and presses the head 51 of the push bar 50, the push bar 50 Enters from the insertion space 28 formed between the lamp body chassis 20 and the side surface 42 of the lens 40, and the pressing jaw 55 at the tip presses the coupling wing 43 of the lens 40 to the lens ( 40) and at the same time pressing and simultaneously pressing the LED module 30 so that the back surface of the LED module 30 is in close contact with the lamp body chassis 20, the module coupling part of the lamp body chassis 20 ( 21) by inserting the LED module 30 into the coupling, and then inserting the coupling wing 43 of the lens 40 into the lens coupling part 22 to couple it, and then to separate it from the lamp body chassis 20, which is a lens fixing means. of the push bar 50 is inserted into the insertion space 28 formed between the lamp body chassis 20 and the side surface 42 of the lens 40, and the lamp body chassis 20 is attached to the outer frame of the luminaire 10. When coupled to (11), the head (51) of the push bar (50) is pressed in close contact with the outer frame (11) of the luminaire (10) and the push bar (50) is formed on the side of the lamp body chassis (20) and the lens (40) As it slides in the insertion space 28 formed between 42, the pressing jaw 55 at the tip presses the coupling wing 43 of the lens 40 toward the LED module 30, and the rear surface of the LED module 30 is a lamp. It is closely fixed to the module coupling part 21 of the body chassis 20 .

At this time, the reflective surface 12 and the light transmitting surface so that the light source projected through the light transmitting surface 41 of the lens 40 coupled to the lamp body chassis 20 is evenly distributed to the reflecting surface 12 of the luminaire 10 . It is very important to match the angle of (41).

Therefore, as a result of the experiment conducted by the present applicant, when the inclination of the reflective surface 12 of the luminaire 10 is 14° in the horizontal direction, the light transmitting surface 41 of the lens 40 opposite to this has the most inclination of 13° in the vertical direction. It was ideal.

Here, both side surfaces 42 of the lens 40 are enlarged forward so that the light passing through the convex lens unit 46 is not refracted, and has the most ideal 30° inclined surface for guiding the light to be projected onto the light-transmitting surface 41 . The inclination angle of both side surfaces 42 is found in a number of experiments in consideration of the fact that the light source of the LED has straightness.

At this time, the inclination angle has a margin of about 5°, but it is most ideal to have a 30° inclined surface found in the present invention when considering the efficiency and everything according to the configuration of the lamp.

And the convex lens part 46 constituting the light emitting lamp receiving groove 45 of the lens 40 is R 1.5, and what is important here is that the light emitting lamp 31 of the LED module 30 is installed in the light emitting lamp receiving groove ( 45) and the light emitted from the light emitting lamp 31 cannot be scattered to the outside on the LED module, and even if the lens is thermally deformed, it is configured so that it does not have any effect on the light emitting lamp 31.

The present invention, as it is essential to use the indirect LED light as a home ceiling light, has great industrial use value.
