New type of description: [Technical field of the new type] The present invention relates to an LED lamp comprising a plurality of LEDs (Light Emitting Diodes, the same applies hereinafter) arranged in parallel on a substrate of an elongated plate-like body, and The LED tube used in the LED lamp. [Prior Art] In the past, LED lamps used LED modules to greatly extend the service life, improve economy, and directly use the lamp holders on both sides of conventional fluorescent lamps to reduce heat generation to improve efficiency and improve heat dissipation. An efficient LED lamp is known (refer to Patent Document 1). Further, the terminal portion structure is also known to correspond to the diameter of the trapped end surface portion of the lamp holder of the conventional fluorescent lamp lighting fixture. This technique is also known (refer to Patent Document 2). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 3, 142, 652. [News] However, as shown in Fig. 8, a conventional LED lamp 1 is A plurality of LEDs 4b are formed on the elongated printed circuit board 4a to form the LED module 4. The LED module 4 is simply mounted on the semi-cylindrical susceptor 8, and is shielded by a semi-cylindrical cover 5. Above it, the lamp holders 6, 7 are used to fix both ends thereof, and are irradiated downward. Further, the heat generation of the LED 4b is merely a fin for forming heat dissipation in the longitudinal direction of the inside of the susceptor 8. The problem to be solved by the L ED lamps and tubes of the present invention is to consider the shape of the M399284 reflector to achieve an increase in the illumination range of the LED and to increase the illumination. Therefore, the LED lamp of the present invention is composed of a reflective plate that is elongated in a single direction and an LED tube that is juxtaposed to the inside of the reflector and is juxtaposed; the LED lamp tube includes: substantially parallel to the foregoing a heat sink on the inner side of the reflector, an LED illuminator mounted on one side of the longitudinal direction of the heat sink, or a transparent or translucent layer that shields the LED illuminator and has a length substantially the same as the length of the heat sink in the longitudinal direction a cover body (an engagement portion of both end portions in the short-side direction of the cover body is fixed at both end portions in the short-side direction of the heat dissipation plate), and an end attached to the longitudinal direction of the heat dissipation plate and the LED light-emitting body And a cover body having a terminal for LED power supply; the heat dissipation plate is disposed such that an outer peripheral portion of the heat dissipation plate is exposed and is limited to a range of 1/3 to 1/4 of the entire circumference of the lamp tube, and the heat dissipation plate is inside and outside the tube The circumference is limited to the upper half of the center portion of the aforementioned lamp tube, thereby expanding the illumination range of the LED. In addition, the LED lamp of the present invention comprises: a heat sink, an LED illuminator mounted on one side of the longitudinal direction of the heat sink, shielding the LED illuminator and having a length substantially longer than a length of the heat sink. The same transparent or translucent cover (the engaging portions of the both end portions in the short-side direction of the cover are fixed at both ends in the short-side direction of the heat-dissipating plate), and the heat-dissipating plate and the LED are mounted a cover body having a terminal for LED power supply at an end portion in the longitudinal direction of the body; the heat dissipation plate is disposed such that an outer peripheral portion of the heat dissipation plate is exposed and limited to a range of W3 to 1/4 of the entire circumference of the bulb, and The inner and outer peripheral portions of the heat dissipating plate are confined within the upper half-4 - M399284 with respect to the central portion of the aforementioned lamp tube, thereby expanding the irradiation range of the led. Preferably, the heat sink is provided with a vent hole for cooling. Furthermore, the LED lamp of the present invention comprises: a cylindrical transparent or translucent cover; and an LED illuminator comprising: a printed circuit board for LEDs fixed to the inside of the cover by a fixing means, and a package A plurality of LEDs on the 'illumination side of the printed circuit board; and LED power supply terminals and a cover provided at the end portions of the LED light-emitting body and the long side in the direction of the cover. Further preferably, the LED light-emitting body is composed of a printed circuit board and a plurality of LEDs mounted on the printed circuit board, and the LEDs are arranged in two rows along the longitudinal direction of the printed circuit board, and each of the columns The pitch is a half-pitch offset from each other and a zigzag configuration in the long-side direction, whereby the irradiation efficiency can be improved. According to the LED lamp of the present invention, the heat dissipating plate is disposed such that the outer peripheral portion of the heat dissipating plate is exposed and is limited to the range of W3 〜1 /4 of the entire circumference of the lamp tube, and the inner and outer peripheral portions of the heat dissipating plate are limited to each other. Within the upper half of the center of the lamp tube, the illumination range of the LED is widened, and the room can be efficiently illuminated by the reflective 'plate. Further, since the reflecting plate can be irradiated to the front efficiently, the power consumption is reduced under the same illuminance, and the cost can be reduced. According to the lamp of the present invention, the irradiation range is widened and the power consumption is reduced. Further, with regard to the structure of the lamp tube, the number of parts is reduced, the weight is light, the manufacturing cost can be reduced, and inventory management becomes easy. By providing a vent hole in the cover or the heat sink, the heat dissipation effect can be further promoted. Further, in the LED illuminator, the LED illuminator is arranged in a zigzag manner on the printed circuit board in the longitudinal direction, whereby the LED illuminator can be uniformly illuminated. [Embodiment] The LED lamp of the present invention reduces the heat radiating plate for the illuminating body of the LED lamp tube, and shields the periphery of the LED lamp tube to expand the light irradiation range more than ever. [Embodiment 1] As shown in Fig. 1, the LED lamp 1 of the present invention is constituted by a thin semicircular arc reflecting plate 2a and a reflecting plate LED lamp la. As shown in FIGS. 1 and 7B, the LED lamp 1a includes a heat dissipating plate 3a that is engaged with the reflecting plate 2a, and an LED illuminating body 4 that is attached to the heat dissipating plate 3a. The cover 5 is transparent or translucent to the length of the heat dissipation plate 3a. The two-part portion in the short-side direction of the cover is fixed to the end portions of the heat-dissipating plate 3a and the LED light-emitting body 4 in the longitudinal direction of the short-side direction of the heat-dissipating plate 3a: the LED power supply terminal 6a is provided. The lid body 6 and the cover body 7 are independent of the power source 9 (refer to Fig. 4). The heat dissipation plate 3a of the LED tube la is narrowed to a width of about 15 mm to 20 mm in the longitudinal direction of the longitudinal direction (see, for example, an arc-shaped shape exposed in the circumferential direction of the tube, and the LED is attached thereto. The reflector plate with the LED lamp in one direction is in the direction of 2 a inside the table 7 A and the parallel 倂S 4, the card portion of the same end portion is shielded, and the short side of the device for fixing the front is fixed) For example, the angle of the center of the circle of the lamp -6-M399284 la is 90° or less. Further, the inner and outer peripheral portions 3e of the heat radiating plate 3a are confined to the upper half of the central portion of the bulb 1a. As shown in the figure, a gap portion is formed between the outer peripheral portion of the arc-shaped region exposed in the circumferential direction of the bulb and the inner and outer peripheral portion 3 e of the tube. In this manner, the light of the LED illuminator 4 is diffused and irradiated in the lateral direction by narrowing the width of the heat radiating plate 3a, and is reflected downward by the reflecting plate 2a. - The heat sink 3a is made of aluminum. In the first embodiment, the LED illuminator 4 is a ?-column having a small amount of heat generation. Further, as for the shape of the reflecting plate 2a, as shown in Figs. 6A and 6B, the entire shape is a shallow bottom. The reflector 2a is an anodizing treatment of an aluminum substrate, and the reflecting surface thereof is covered with a glass by PVD. The reflection angle of the reflecting surface is adjusted so that the light of the L E D luminous body 4 is totally reflected toward the ground direction, whereby the illuminance can be efficiently improved. Further, in order to reflect the light of the LED 4b downward, the depth of the reflecting plate 2b may be deep as shown in Fig. 6C. ^ The reflector 2a is fixedly attached to a fixture such as a ceiling (not shown), and is attached to a ceiling or the like by a known attachment means such as a bracket or a wood screw. The reflector 2a is engaged with the fixture to be suspended. The outer cover lb is covered on the outer side of the reflecting plate 2a. A power source 9 is disposed inside the cover lb. The LED light-emitting body 4 is composed of a printed circuit board 4a and a plurality of LEDs (light-emitting diodes) 4b mounted on the printed board 4a. For example, M399284, which is a TANABAR SLIM (trade name) equivalent, which is a bar module for lighting having a square shape of about 1 square, has a transparent or translucent cover 5, for example, made of synthetic resin. In order to attach and fix the heat radiating plate 3a, the carbon nanotubes are made of a fixed portion in the short-side direction, and the heat-dissipating plate 3a is short from the one end side in the longitudinal direction of the cover 5. After the engaging portion at the end portion in the side direction is fitted, the sliding portion is further slid and inserted, whereby the heat radiating plate 3 a is attached to the cover 5 . The above LED tube la, as shown in Figs. 7A and 7B, can be used not only as a low-power LED tube for a new lamp, but also as an old discharge lamp for an existing lamp. Easily replaced with LED tubes for use. In the above-described manner, the heat radiating plate 3a is disposed such that the outer peripheral portion of the heat radiating plate 3a is exposed and limited to 1⁄4 of the entire circumference of the bulb 1a, and the inner and outer peripheral portions 3e of the heat radiating plate 3a are limited to The inside of the upper half of the center portion of the bulb 1a (upper position) is opened, so that the irradiation range of the LED 4b can be widened. [Embodiment 2] Fig. 2 is a view showing a second embodiment of the lamp of the present invention, which comprises a cover 5a made of a cylindrical transparent or translucent polycarbonate or the like, and an LED illuminator 4 (with: The LED printed circuit board 4a fixed to the inside of the cover 5a by a fixing means, and a plurality of LEDs 4b) mounted on the irradiation side of the printed circuit board 4a are disposed in the longitudinal direction of the LED light-emitting body 4 and the cover 5a. The LED power supply terminal 6a and the lids 6 and 7 at the end (see Fig. 4). As the fixing means M399284 for the LED printed circuit board 4a and the above-described cover 5a, for example, the following structure can be employed. In other words, the lids 6 and 7 are provided with projections that are engaged with the printed circuit board 4a and the like at both end portions in the longitudinal direction, and the lids 6 and 7 are attached to both ends of the cover 5a. Thereby, the printed circuit board 4a is fixed by this. On the back side of the printed circuit board 4a, the vent holes 5c and 5d for heat dissipation are provided in the cover 53. The vent holes 5c and 5d are arranged in a row along the longitudinal direction of the tube or in a zigzag shape. In the figure, there are two places in the circumferential direction, but only one or more are required. The number is not particularly limited. Further, it is preferable that the printed circuit board 4a is provided with a through hole penetrating the upper and lower portions at an appropriate portion. Further, not only the back side of the printed board 4a but also the upper side of the cover 5a and below the position of the printed board 4a, the vent holes 5c, 5d may be provided. 3] Fig. 3 shows a third embodiment of the lamp of the present invention. By exposing the outer peripheral portion of the heat radiating plate 3b and confining it to the range of 1/3 to 1/4 of the entire circumference of the lamp, the LE D4b can be made. The irradiation range is expanded, and the inner and outer peripheral portions 3 e of the heat dissipation plate 3 b are confined to the upper half of the central portion of the bulb, and the outer peripheral portion and the inner and outer peripheral portions 3 e of the tube become hollow portions. . The heat dissipation plate 3b is formed with an exhaust hole 3c penetrating from the outside of the cavity portion on the back side of the L E D luminous body 4 to the outside. The vent holes 3 c may be arranged side by side at an appropriate interval along the longitudinal direction of the tube, or may be arranged in a zigzag shape, and the number of the vent holes 3 c is not particularly limited. The heat is efficiently discharged to the outside. Here, the symbol 3d indicates the fin for heat dissipation of the heat dissipation plate 3b. Ymn&4 [Embodiment 4] Fig. 5 shows a fourth embodiment of the present invention, in which the LEDs 4b of the LED illuminators 4 of the lamp are arranged in two rows along the longitudinal direction of the printed circuit board, and the sections of each column The pitch is offset from each other by a half pitch and is formed in a zigzag configuration in the longitudinal direction. Thus, even when the light is just turned on, the space between the LEDs 4b does not appear dark, and the LED can be illuminated. The whole body appears to emit light uniformly. Thereby, even a small number of LEDs 4b can uniformly illuminate the entire interior of the room. The LED lamp 1 and the lamp 1 a of the present invention have a long life and can expand light, and can be used in various places such as a office, a home, and a management room by preparing various lengths in the longitudinal direction.
