[Prior Art] Among the lighting fixtures for ordinary houses, the following lighting fixtures have been popularized. 'The lighting fixture uses a ring-shaped fluorescent lamp for the main light source to cover the lower side of the circular fluorescent lamp. In this way, a cover (c〇ver) member (shade) is provided and the outer shape is formed into a spherical shape. In recent years, with the increase in the output, efficiency, and generalization of light-emitting elements such as LEDs, lighting fixtures for ordinary homes as described above have been developed which use light-emitting elements as light sources and can be expected to have a long life. On the other hand, as the temperature of the light-emitting element such as an LED rises, the output of light decreases, and the useful life becomes shorter. Therefore, in a lighting fixture in which a solid-state light-emitting element such as a led or electroluminescence (EL) element is used as a light source, it is necessary to suppress the temperature rise of the light-emitting element to improve characteristics such as durability or improvement in luminous efficiency. In the lighting fixture for a general house using an LED as a light source, for example, there is a lighting fixture in which a lighting device that controls lighting of the LED is provided around the mounting portion and is disposed in the vicinity of the lighting device. There are a plurality of LEDs, and the mounting portion is mounted on a ceiling lamp holder provided on the ceiling surface. The LED is disposed such that the light is emitted outwardly in the lateral direction, and the emitted light is reflected by the reflector provided on the ceiling surface side to reflect the front side.

Further, the LED adopts a structure disposed in the vicinity of the lighting device. Therefore, heat generated from the LED and heat generated from the lighting device may interfere with each other, and the temperature of the LED rises due to the heat. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a lighting fixture which is simplified in structure, can easily suppress temperature rise of a light-emitting element, and can image an image of light emitted from a light-emitting element.

Since the same number of light-emitting elements 22 are mounted in this manner, the light-emitting elements 22 can be shifted in position and balanced. (balance) well dispersed in the base 21: The LED package generally includes: an LED chip disposed on a body including ceramics; and a translucent resin for a mold such as an epoxy resin or a silicone resin, sealed The LED chip is a blue LED chip that emits blue light. A phosphor is mixed in the translucent resin, and a yellow phosphor is used to emit white light, and the yellow phosphor emits blue light. In addition, the LED may be mounted on the substrate 21 directly on the substrate, and the cannonball type LED may be mounted on the substrate 21. The mounting method or form is not particularly limited. 2 and 3, the substrate 21 is placed around the mounting portion 4, and the mounting surface of the light-emitting element 22 is disposed toward the front side, that is, the irradiation direction below. Further, the back side of the substrate 21 is disposed. The male body is attached to the inner surface side of the body 1, for example, by a fixing mechanism such as a screw. Therefore, the substrate 21 and the body 21 are thermally dried so that heat from the substrate 21 is conducted from the back side to the body 21 and is 彳^ As shown in FIGS. 2 and 3, the lighting device 3 includes a case having a substantially short cylindrical shape, a circuit board 31 mounted and housed in the case, and a circuit board 31 mounted on the circuit. A circuit component on the substrate. The lighting device 3 is disposed and mounted in a recess u formed in a central portion of the body 1, and is electrically connected to the adapter A side, and is connected to a commercial alternating current power source via the adapter a. The lighting device 3 receives the AC power supply to generate a DC output, and supplies the DC output to the light-emitting element 22 via a wire to control the light-emitting element 22. The women's clothing portion 4 is formed into a substantially cylindrical shape. An adapter guide 'in the center of the adapter guide is provided with an engagement opening through which the adapter A is inserted and engaged. The adapter guiding portion is disposed such that its outer peripheral surface is located on the inner peripheral side of the casing of the lighting device 3, in other words, the lighting device 3 is disposed on the outer peripheral side of the adapter guiding portion. Moreover, the adapter guide portion is inserted through the opening 12 of the body hub to extend to the front side. Further, the 'mounting portion 4 does not necessarily need to be a member called an adapter guiding portion or the like. For example, 'the opening may be formed on the main body 1 or the reflecting plate 6, and mainly means to face the ceiling holder main body Cb as a wiring device and to make it The component or part of the adapter A that is engaged. The cover member 5 includes a light-transmitting material such as an acrylic resin or the like which is milky white and has diffusibility, and includes a circular base substrate 51 formed in a flat shape, and a side edge portion 52 from which The base portion 51 has a circumferential extension extending in the circumferential direction. Also, the cover member 5 covers the light source. The rim 2 is attached to the outer peripheral edge portion of the main body 1 so as to be on the front side of the main body 1. As shown in Fig. 2, the 201215802 40050pif reflector 6 is formed by a flat f of a metal material such as a cold-rolled steel sheet, and has a rounded reflective surface 61, and an opening for operating the adapter A is formed at a substantially central portion. Therefore, part of the light emitted from the light-emitting element 22 is reflected from 61 to the front side, thereby being effectively utilized. The adapter A is electrically and mechanically connected to a portion of the ceiling lamp holder main body provided on the ceiling surface c by hanging fishing provided on the upper side, and has a substantially cylindrical shape and passes through both sides of the peripheral wall. A built-in spring (sprmg) is provided with a pair of locking portions A so as to always protrude toward the outer peripheral side. The locking portion A1 is operated by the operating lever (4) (four) provided on the lower side, and no one is from the adapter A. A power supply line ((4)) (not shown) of the lamp device 3 is led out and connected to the lighting device 3 via a $ (connector). Next, the mounting state of the lighting fixture mounted on the ceiling surface c will be described. As indicated by @2, the ceiling lamp holder main body cb is provided on the ceiling surface c. Further, the adapter A is electrically and mechanically placed on the material body Cb. From this state, as shown by the arrow in the figure, the engagement opening of the adapter guide portion of the attachment portion 4 is aligned with the adapter a, and the device body is pushed up by the hand from below until the card front portion of the adapter A is surely The snap-fit port of the adapter bow guide is engaged to perform the mounting operation. Further, when the apparatus body is detached, it can be disassembled by removing the cover member 5 and holding the operation lever provided on the adapter a to release the engagement of the locking portion A1 of the adapter A.

The light emitted from the light-emitting element 22 is transmitted to the outside through the cover member 5. In this case, since the light-emitting elements 22 are shifted from each other and are well-distributed in a well-balanced manner, the brightness of the thief light unit 2 can be uneven, and the image of the light emitted from the multi-figure light-emitting element can be made uniform. In addition, since the substrate 21 is located around the mounting portion 4 and the mounting surface of the light-emitting element 22 is disposed toward the front side, simplification of the structure can be achieved, and the heat from the substrate 21 can be easily configured. Heat dissipation structure. For example, as in the present embodiment, it is possible to easily realize a structure in which the back side of the substrate 21 is thermally bonded to the body 丨, and heat from the substrate 21 is conducted to the body 21 and is radiated. Thereby, the temperature rise of the i-ray element 22 can be suppressed. In addition, since the lighting device 3 is disposed on the outer peripheral side of the mounting portion 4, the substrate 21 is located around the mounting portion 4, and the back side is thermally coupled to the body i, so that heat generated from the lighting device 3 and the light-emitting element are obtained. The thermal interference between the generated heats of 22 is alleviated, so that the temperature rise of the light-emitting elements 22 can be effectively suppressed. Next, a second embodiment of the present invention will be described with reference to Fig. 5 . Fig. 5 shows the plane of the light source unit 2 in the same manner as Fig. 4 . The same or equivalent portions of the first embodiment are denoted by the same reference numerals and the description thereof will not be repeated.

Therefore, the same number (44) of light-emitting elements η in each row are many m on the circumference of a substantially concentric circle having different radii, and between adjacent columns (the inner circumference side and the center side column, the center side) And the rows on the outer peripheral side are arranged to be shifted in the circumferential direction. In the same manner as in the first embodiment, since the same number of light-emitting elements 22 are mounted in the respective rows, the light-emitting elements 22 can be shifted in position and distributed on the substrate 21 in a well-balanced manner, and can be emitted from the plurality of light-emitting elements. The image of the light is homogenized. The present invention is not limited to the configurations of the above-described embodiments, and various modifications can be made without departing from the spirit and scope of the invention. For example, the <,, and the luminaire may be a direct type mounted directly on the ceiling, or a pendant type or a ceiling type suspended from the ceiling. Further, on the substrate, the light-emitting elements may be arranged in a plurality of rows on a circumference of a polygonal shape having substantially the same center size, and may be arranged so as to be shifted in the circumferential direction between adjacent columns. Quantity women's exam. Specifically, assuming that a light-emitting element is mounted on the circumference of a hexagonal polygon, 'there is a case where the circumference of the inner hexagon is 12 201215802 % 40050pif s the circumference of the hexagon on the second side The light-emitting elements are arranged upward, and the light-emitting elements arranged inside are arranged in a circumferential direction with the light-emitting elements arranged outside. The substrate is preferably formed into a circular annular shape or a hexagonal or octagonal shape, but it is secretly defined. In short, as long as the illuminating light can be placed on the circumference or on the circumference of the polygon, the shape of the job board is not special. Further, the substrate may be divided into a plurality of pieces, and these plates may be combined to form the whole. Further, in order to increase the uniformity of the light radiated from the light source unit, a diffusion lens may be provided in accordance with the light-emitting element, or a light transmittance control mechanism may be provided on the cover member. Further, the light-emitting element can be applied to a solid-state light-emitting element such as an LED or an organic EL. The number of the light-emitting elements and the number of columns are not particularly limited.
