Description of the Invention: [Technical Field] The present invention relates to a street lamp, and more particularly to a street lamp having an elliptical light-emitting diode that can increase an irradiation range. [Prior Art] The streetlights of the transmission and charging are mainly composed of white woven lamps and photographic lamps. Incandescent lamps are the oldest sources of light and are still widely used today. The principle of the white woven lamp is to use the current to generate high heat through the filament to emit light. Because the crane wire has the characteristics of melting point south and low evaporation rate, the current filament is all the crane wire, in addition to the crane wire inside the lamp, in addition It is filled with an inert gas to reduce the rate of the crane 4 to prolong its life. The most important feature of incandescent lamps is the cost-benefit/brightness H and continuous dimming; but the disadvantage is that the efficiency is low, causing the large 4-knife electric^ to be radiated in the form of heat, so it will generate high heat when energized. Its life span is short, and the number of hours of use generally does not exceed one thousand hours. The principle of illumination of a halogen lamp is similar to that of an incandescent lamp. The difference is that the tooth lamp is filled. The halogen in the lamp and the filament are produced in a (four) cycle, so that the efficiency and life of the lamp are higher than that of the incandescent lamp. Because of its excellent color temperature and color rendering, and a fairly good light collection, point lighting source. Halogen lamps are as inefficient as incandescent lamps, and the disadvantages of large amounts of heat dissipation are also limited, resulting in a short life span of more than two thousand hours. Due to the rapid advancement of technology by Ik, the existing ^^ has gradually benefited from the lack of low service life of incandescent lamps and halogen lamps replaced by light-emitting diodes (LEDs) and high-power LEDs. Although the light-emitting diode has the advantages of power saving and long life, the only drawback is that the household of the light-emitting diode is only concentrated in the middle of the light-emitting head, and the light shape is unchanged. Used with secondary optics, not only high optical loss, but also poor light efficiency. Therefore, the application of the light-emitting diode and the high-power light-emitting diode to the street lamp alone requires a substantial increase in the power of the street lamp, but the power-saving efficiency is greatly reduced. Referring to Fig. 1, it is a partial view of a street lamp of a conventional light-emitting diode. Therefore, generally, a street light of a light-emitting diode (LED) is used. To enhance the illuminance (Lux, candlelight), it is necessary to cooperate with a lens (Lens) applied between the light-emitting diode (LED) 101 and the lamp housing body 102. ) 1〇3, to improve the illumination of the light source of the street lamp by the use of secondary optics. Although the high-power light-emitting diode 1〇1 plus the lens (Lens) 1〇3, the street light 100 can meet the requirements of the specification by the application of the primary optics. However, the addition of the lens (Lens) i 〇 3 not only greatly increases the area of the lamp body of the entire street lamp, but also the area of the circuit board (pCB) 1〇4, and the assembly is not easy; in addition, the lens (Lens) l The volume of 〇3 has occupied the area of the lamp shell, which caused the arrangement of the illuminating diodes 1〇1 to be too scattered, which in turn caused the light source of the entire illuminating diode group to be concentrated, thereby affecting the overall illuminance of the street lamp 100 (Lux ). Referring to Fig. 2, a plan view of a street lamp 100 of a conventional light-emitting diode, on which a light source is irradiated on a road surface 105. 6 1312398 1丄 Refer to Figures 1 and 2. Due to the limited range of source illumination of the existing light-emitting diode street lamp 100, the use amount of the product 100 street light 100 is particularly increased on the road surface of the key illumination, so that although the light-emitting diode has a power-saving effect, Under the premise of the increase in the number of street lamps (10) and the addition of lenses (Lens) 103, the overall material cost and electricity cost are relatively higher; therefore, in the case of global energy decline, it is indeed necessary to seek solutions. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a street lamp having an elliptical light-emitting diode, and an elliptical light-emitting diode that generates an asymmetric light source is coupled to a street lamp to solve the existing street light using the light-emitting diode. The secondary optics cause shortcomings such as increased volume of the lamp group, difficulty in amplifying and assembling the circuit board, and the like. According to the above object of the present invention, a street lamp having an elliptical light-emitting diode is provided, comprising a light pole, a lamp housing body, and a plurality of elliptical light-emitting diodes.

Referring to Fig. 6, a plan view in which a plurality of elliptical light-emitting diodes are arranged in the body of the lamp housing is shown. Referring to Fig. 7, it is a side view of an elliptical light-emitting diode. Referring to FIG. 4, FIG. 6, and FIG. 7, the elliptical LEDs 300 may be arranged in an array on the circuit substrate 230 and housed inside the lamp housing body 220. Each of the elliptical LEDs 300 has a power 1312398 310, a light emitting diode lens 320, and two wafer main terminals 330 of at least iw. Referring to Fig. 5, it is a perspective view of a rounded light emitting diode. / Referring to FIG. 5, FIG. 6 and FIG. 7, the light-emitting diode lens 32 is "on the wafer main body 31" and the light-emitting diode lens 32 has a transmissive portion 32. The transmissive portion 321 is a three-dimensional semi-elliptical shape and has a _ section 3211. In the present embodiment, the elliptical cross section η is such that the transmissive portion 321 is adjacent to the surface of the wafer body 31. The circular expansion section 3211 has a long axis X and a short axis Y, wherein the ratio of the light shape scattered by the major axis X and the minor axis γ is greater than or equal to 15 to 5, that is, the illumination of the major axis X and the minor axis Υ The light shape ratio is between 1.5 and 5.
