Description of the Invention: [Technical Field] The present invention relates to a lamp, and more particularly to a light-emitting diode lamp. [Prior Art] Since the light-emitting diode lamp using the light-emitting diode emits light in the electro-optical conversion efficiency of converting electric energy into light energy, compared with the electro-optical conversion efficiency of the old-style mercury fluorescent lamp, the electro-optic light of the light-emitting diode lamp The conversion efficiency is higher and the power is saved at the same brightness; in addition, the mercury fluorescent lamp often flickers after aging and causes eye discomfort; therefore, the fluorescent diode lamp has been gradually replaced by a mercury fluorescent lamp as a light source. Referring to FIG. 1 'A general LED lamp 1 includes a tube body 复, and a plurality of LEDs 12 accommodating the tube body 11. The LEDs 12 are arranged in a row and are accepted. Electrical energy can be converted into light energy when the outside energy is used. The tube body 11 has a transparent light-transmitting light-emitting portion m. When the light-emitting diodes 12 emit light, the light passes through the light-emitting portion U1 to emit light outward. Since the light-emitting diodes 12 are disposed on the inner peripheral surface of the tube U and can emit light only in a specific direction. Therefore, even if the tube body u is transparent and transparent, the light emitted from the light-emitting diodes 12 is still only up to (10). The viewing angle of the remaining light from the light-emitting diodes 12 is in the dark band, and the dark band is as high as 18 inches. Or greater than i8〇. In other words, 'the current light-emitting diode lamp! It is necessary to be in contact with the light-emitting diodes on the same side to receive light from the light-emitting diode lamp. [Description of the Invention] 201248080 Therefore, the object of the present invention is to provide a light-emitting diode lamp with an increased viewing angle. Therefore, the light-emitting diode lamp of the present invention comprises a light-conducting body 'complex chamber' and a light source unit. The light-guiding body is formed of a transparent material and is formed in a straight rod shape. The chambers are formed in a non-connected manner with each other. In the light guiding body; the light source unit has a light emitting diode that emits light when a plurality of power supplies are supplied. The light emitted by the light-emitting diodes from the one end of the light guiding body enters the light guiding body and is transmitted to the opposite end portion, and the light is transmitted in the light guiding body due to the existence of the chambers And changing the direction of travel and then leaving the light guiding body to the outside. The effect of the invention is that the light emitted by the light-emitting diode during power supply controls the light travel path by the refraction of the chambers, and the light is emitted outward from the outer surface of the light guide body to make the light 360. The ground emits light, which greatly increases the viewing angle of the light-emitting diode lamp. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Before the present invention is described in detail, it is to be noted that in the following description, like elements are denoted by the same reference numerals. Referring to Figures 2 and 3, a first preferred embodiment of the LED lamp 2 of the present invention comprises a light guiding body 21, a plurality of chambers 22 formed in the light guiding body 21, and a light source unit 23. The light guiding body 21 is formed in a straight rod shape, and the wearing surface 201248080 in the direction of the vertical long axis is circular. The light guiding body 21 is made of a transparent material so as to be transparent and transparent, and the light entering the light guiding body 21 is refracted at an angle and then passed out. In the first preferred embodiment, the transparent material is exemplified by pressure grams, but not limited by the pressure. The chambers 22 located in the light guide body are elongated and spaced apart from each other and formed on the light guiding body 21 at intervals, and each of the chambers 22 extends along the long axis direction of the light guiding body 21 and penetrates the The light guide body 21 contains air. «The sinusoidal chambers 22 are symmetrically arranged with each other centering on the major axis of the light guiding body 21, and if the cross section is perpendicular to the long axis direction of the light guiding body 21, the chambers 22 are surrounded by a ring shape, and The diameter of the center of the long axis of the light guiding body 21 away from the center of the long axis of the light guiding body 21 may be regarded as an approximately radial pattern. The light source unit 23 includes a side cover 231 and a plurality of light-emitting diodes 232 that are electrically converted into light when supplied. The side cover 231 is formed in a thin plate shape and is connected to one end of the light guiding body 21 to shield the side of the chamber 22 adjacent to the side cover 231. The light-emitting diodes 232 are disposed on a side of the side cover 231 adjacent to the light guiding body 21, and the light emitted by the power supply is directed toward the light-emitting body of the straight bar shape. Preferably, the light emitting diodes 232 are combined with each other on the side cover 231 at intervals and in a ring shape. When the light-emitting diode 232 connected to the side cover 231 of one end portion of the light guiding body 21 receives electric energy and emits light, the light is directed to the light guiding body along one end portion of the light guiding body 21 in which the chamber 22 is formed. The other end of the 21 transmits '· during the progress of the light, part of the light is changed by the chamber 22 so that the refractive index of the medium is different from the refractive index of the transparent material forming the light guiding body 21, 6 201248080 The original traveling direction further emits light outward, and part of the light continues to travel along the long axis direction of the light guiding body 21; the light continuing to travel along the long axis direction of the light guiding body 2丨 passes through the chambers 22 and The light guide body 21 is refracted to emit light outwardly. This process is repeated until the light guide body 21 emits light from the one end portion to the other end portion of the connection side cover 231 as a whole. Illuminated LED lamp 2. Since the chamber 22 of the LED lamp 2 is arranged in an annular structure centering on the long axis axis of the light guiding body 21, the light emitted from the LED 232 is also distributed through the evenly distributed chamber. 22 controls the light traveling path, and cooperates with the light guiding body 21 to provide a viewing angle. That is, the non-visible angle limit is outwardly illuminated, which is much larger than the maximum viewing angle of the current LED lamp: 180. . With reference to Fig. 4, it should be noted that the light source unit 23 may also include two side cover seats 231 respectively disposed on the opposite side of the light guiding body 21 and provided for the light emitting diodes 232. When the diode is powered, the light traveling symmetrically along the long axis direction of the light guiding body 21 can be simultaneously emitted; the light emitted from the end portions of the light guiding body 21 passes through the chambers 22 to control the traveling path from It is softer, more symmetrical and uniform when shining outward. References _2, 5, and 6' Fig. 5 and Fig. 6 are external (four) illuminance distribution maps: The X-axis, the y-axis, and the z-axis of FIG. 2 are the seat & axial direction of the coordinates indicated in FIGS. 5 and 6, and the soft simulation is taken as a specific example in the first preferred embodiment. The specific examples are similar and differ in that a light-emitting diode lamp having no I-cavity to 22 is used as a comparative example (not shown), and the external irradiance distribution of both is simulated and measured. _ 5 is the simulation of the specific 201248080 】 The distribution of the external illuminance at the time of power supply ® ' 6 is the simulation of the external illuminance distribution when powering the comparative example, as can be seen from the figure, the overall example of the specific example 2 The average irradiance is 43 W/m2, and the maximum irradiance is 396 W/m2. The overall average irradiance of this comparative example is 34 W/m2, and the maximum irradiance is 270 WM2. Therefore, from the simulation data, the overall average Koda of this specific example is obtained. The illuminance is higher than the overall average irradiance of the comparative example having no such chambers; and FIG. 5 and FIG. 6 again, the illuminance difference of the light guiding body of the specific example from the both ends and the middle portion along the z-axis direction is observed. It is not large, that is, the light emitted by each part of the specific example is substantially average and has a large average irradiance compared with the comparative example; and the illuminance of the comparative example along the z-axis gradually decreases from the both ends to the middle. As a result, the illuminance of the both ends and the middle portion is not uniform, and even the light illuminance distribution pattern of the near-outer portion of the z-axis middle portion of the comparative example is shown to be close to black, that is, the illuminance at the middle portion is very low. It should be noted that the first preferred embodiment may further include a medium (not shown) filled in the chambers 22, and the refractive index of the medium is 1·4~1·7'. The preferred embodiment can also control the light travel path more precisely by matching the chambers 22 by filling the medium in the chambers 22 to control the angle of travel of the light. Referring to FIG. 7A, a second preferred embodiment of the LED lamp 2 of the present invention is similar to the first preferred embodiment except that the light guiding body 2 of the second preferred embodiment is further The microstructures 21 formed on the outer surface of the plurality of light guides 21 are regularly distributed gradually from the two ends of the light guide body 21 to the middle portion of the light guide body 201248080, and can be sandblasted and ground. The microstructure 211 of the light guiding body 21 is fabricated by a process such as coating. When the light-emitting diode 232 emits light, light can be made 360 in addition to the refraction of light by the chambers 22. The light is emitted from the light guiding body 21 to the outside, and the light is further refracted at a plurality of angles through the microstructures 211, and the light reaching the outer surface of the light guiding body 21 is also reflected by the microstructures 211. Illuminating at multiple angles, the light can be more uniformly illuminated at 36 〇<>; in addition, since the light is strongest at both ends and gradually weakens as it travels to the middle portion of the light guiding body 21, the light can be utilized The microstructures 211 of the light-conducting body 21 from the two ends to the middle end gradually make the light retreat a plurality of times by the dense microstructure 211 when the light travels to the middle portion, thereby increasing the chance of the light beam refracting outward to compensate The intensity of each beam traveling to the middle section is insufficient, and the light intensity emitted at both ends and the middle section of the light guiding body 21 is uniform and substantially similar. In summary, the light-emitting diode lamp 2 of the present invention utilizes a transparent light-guiding body 21 to fit a plurality of cavities 22 extending in the longitudinal direction of the light-guiding body 21 to increase the chance of light refraction. Hey. The outward illumination, and the use of the microstructures 211 again increases the number of times the light is refracted and reflected, so that the outwardly emitted light is more uniform, so that the object of the present invention can be achieved. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
