When, the LED indoor luminaire of the present invention can also be used without the suspension member 128: ❹疋 is fixed in cooperation with the ceiling or other structure of the house. The support frame 14 serves as a base body for arranging the LED modules 2, and includes four tapered cylinders 14a to 14d made of a high heat conduction steep material, and four fixing members 15 for the cylinder. In this embodiment, a cross section is rectangular in shape and is composed of four isosceles trapezoidal plates. The female-tapered cylinder 14a forms a small-diameter end and a large-diameter end. The trapezoidal plates of the four tapered cylinders 14a to 14d have the same height, but the cross-sectional size of the same height from the taper: 14a to the tapered cylinder 14d gradually becomes smaller. Each of the corners of the corresponding large-diameter ends of the tapered cylinders 14a to 14d is provided with a solid. The 201017065 fixed projections 140a to 140d' are provided with internal threads for each of the fixing projections 14a to 14d.

The cones 14a to 14d correspond to the position of each LED module and have a through hole for the wires of the LED module to pass through. . Referring to FIG. 6 at the same time, the four tapered cylinders Ua to 14d are coaxially stacked with the smallest dimension ❹=the axis of the tapered cylinder 14d (in this embodiment, the shaft refers to the connecting line of the center of the two ports of the tapered cylinder). (stacked), the largest size cone W is located on the outermost ring, the smallest size is located in the innermost circle, and the corresponding trapezoidal plates between the cones have the smallest spacing of the cones of 2 and 2 The diameter of the four cones 14^ is gradually increased from the outer ring to the inner ring, that is, the difference between the adjacent cones 14a to 14d, thereby The power supply circuit installed centrally with the frame 1 “ LED LED LED LED indoor luminaire as a whole is far away from the back cover to the small diameter end of the micro-bumps 14a to 14d toward the side away from the back cover η: the mother-conical cylinder 14a ~14d forms four planes inclined by a certain angle upwards, with an inclination of 3 〇. Odd to ^ = another: two ritual f 14 is through the cone cylinder... with the back cover 12 knot: at the start, and the cone When the cartridge 14a is assembled, it is abutted against the outer periphery of the outer edge 12 of the large open end of the tapered cylinder 14a, and the horizontal edge 12 of the heart and the back cover 12: The flange extending member 15 is a long strip body, and each fixing member 15 is provided with five fixing holes 152 of a distance of 201017065, wherein two fixing holes 152 are located at two ends of the fixing member 15. Each fixing The four immediately adjacent fixing holes 152 of the member 15 correspond to the fixing projections 140a to 140d at the corresponding corners of the four tapered cylinders 14a to 14d, and the two are locked by screws or the like. The LED module 20 includes a long strip. The circuit board 22 and the plurality of LED units 24 integrated on the circuit board 22. The LED module 20 is disposed in a horizontal direction on each of the outer surfaces of the above-mentioned tapered cylinders 14a to 14d, and the circuit board 22 of the LED module 20 Parallel to the plane of the cones 14a to 14d, and two LED modules 20 are arranged in a flat shape on each plane of the tapered cylinder 14a of the outermost outer ring, on each plane of the tapered cylinders 14b to 14d. An LED module 20 is disposed. The LED module 20 is disposed on the cones 14a to 14d, and then the light guide cover 30 is disposed on the LED module 20. The light guide cover 30 is composed of a top cover 32 and The edge 34 is formed, and the overall contour matches the shape of each plane of the cones 14a-14d in a trapezoidal shape, and the top cover 32 mainly forms an accommodating space. The LED module 20 is covered, and the edge 34 is used for fixing to the cones 14a to 14d. The power circuit module 40 includes a rectangular box 42 having a desired circuit 44 therein. The casing 42 is covered with a cover 46, and a through hole is formed in the center of the cover 46 for the suspension member 128 on the back cover 12. The required circuit 44 may include a driving circuit, a control circuit, a voltage stabilizing circuit, and a current. The power circuit module 40 is disposed at the center of the innermost cone-shaped cylinder 14d, and the four corners of the box body 42 are provided with fixing holes 48 for mounting with one end of each fixing member 15 Locking. Referring to FIG. 6 again, after assembly of the LED indoor lamp, a plane which is inclined along the central axis of the 201017065 cones 14a-14d away from the back cover 12 and which emits light outwardly and the cones 14a-14d are formed. The inclination (taper), the distance between the planes of the cones .14a to 14d, and the height difference between the cones 14a to 14d make the vertical light emitted by the LED module 20 not be adjacent to the cone Blocked by 14a~14d. In other words, at least part of the main light emitted by the LED module 20 on the inner cones 14b to 14d (for example, the light perpendicular to the light emitting surface of the LED module 20) is irradiated on the outer cylindrical cones 14a to 14c. In addition to the projection range (projection area) in the light-emitting direction, that is, the light emitted from the LED module 20 on the tapered cylinders 14b to 14d of the inner ring at least perpendicular to the light-emitting surface of the LED module 20 itself and the cone of the outer ring The annular band regions surrounded by the projection lines of the cylinders 14a to 14c in the light-emitting direction do not overlap, and therefore the main light emitted from the LED module 20 is not irradiated onto the tapered cylinders 14a to 14c of the outer ring. Since the light of the LED indoor luminaire of the present invention is inclined outwardly, the irradiation area thereof is relatively wide, and the light is uniformly softened due to the parallel illumination of the plurality of LED modules 20. In addition, the support frame 14 on which the LED module 20 is mounted is a combination of relatively independent cones 14a to Ud, and the structure thereof is flexible and stable in terms of manufacturing and modification, and subsequent maintenance. The operable elasticity is relatively large, and the cost is relatively low. Further, the number of the cones 14a to Ud can be appropriately increased or decreased according to the demand, thereby correspondingly enhancing or reducing the illumination brightness of the light. It can be understood that the cross-sectional shape of the cone of the LED indoor lamp of the present invention may be a polygon such as a triangle or a pentagon, and the size or the number of the LED module may be converted into a cone according to the shape of the cone. The size of the plane is more matching the size or number. The more the number of sides of the polygon, the led room 11 201017065 ί::=! Installed in a direction parallel to the edge of the barrel:::: 耆 and the edge of the cone (four) are installed perpendicularly. In addition, the shape of the back cover and the circuit case also varies with the shape of the cross section of the cone. In summary, the present invention complies with the requirements of the invention patent and loves to apply for the law. The above is only the preferred embodiment of the present invention, and those skilled in the art will be able to devise equivalent modifications or variations in the spirit of the present invention.
