M383086 V. New description: [New technical field] The present invention relates to a light-emitting diode lamp, and more particularly to a lamp for outdoor lighting. [Prior Art]

The conventional street lamp structure is mostly a mercury lamp or a halogen lamp which is joined to one end of the end of the vertical pole. One or more light bulbs or light-emitting elements are arranged in the lamp, and the lamp is provided with a reflector to reflect the light source to achieve night illumination. The purpose. A conventional mercury lamp or a tooth lamp type street lamp is basically a lighting device with high energy consumption and short life compared with a led lighting device.

The light-emitting diode has the characteristic of beam concentration, but the brightness of the LED is not as good as that of the eye a few years ago. Therefore, it is only used for signal lights, rear lights or decorative lights, and the blue LED eye shape and its price drop in recent years. Thanks, the application of white LED is more extensive. _ is advertised as energy-saving and carbon-reducing today. Governments of various countries are not willing to take political or technical support. 13 This is generally expected that LED will replace incandescent lamps as the main lighting supplier. Different from the principle of illumination of incandescent bulbs, it is called cold cathode. It does not, it is very power-saving and as long as it is properly dissipated, its service life can reach tens of thousands of small incandescent bulbs. The conventional LED street light fixtures are often composed of dozens of (10) arrays. After the light distribution, there will still be a bottle angle. But the tool itself does not have the _ angle of Wei. Silk, the whole LED lamp is in the dimension h, the whole T (four) wire must be used to repair the ball from the inconvenience. 3 M383086 In view of this, the present invention provides a modular lamp tube for outdoor lighting, which can be used in [new content]. The novel discloses an LED, and b, comprising: a lamp housing, the shape of the lamp shell is approximately semicircular _ The long strip body has a platform inside the strip body, and the wrap board containing the wafer is placed on the platform; the plurality of fins are expanded in a double wing shape and the fins are arranged at intervals in the strip body. On the appearance. 2. A plurality of storage strips are provided on the _ of the approximately semi-cylindrical body at the ends of the substantially semi-cylindrical body to provide the lamp tube device. When the lamp tube bearing base is provided with a relative tooth groove, the axis can be adjusted. The towel ^ line field turns to the rotation of Ke Xiaodu. Outer buckle and screw lock 'This: There is a power cord and a thin circuit:;==: [Embodiment] The following description is accompanied by the illustration. In which, according to an embodiment of the present invention, the LED in the illustration The circuit board is only an example and is not intended to limit the patent details of the present invention. For example, the LED circuit board towel D-crystal (four) is limited to the one shown in the figure, it can be a single row of multiple ❹ 颗 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , In the example, it is a single row, or a double row, so that each LED die can obtain the closest heat dissipation condition. The remaining perspective view of the lamp tube housing 1G and LEi) circuit board 8G which is not disclosed in the present invention is shown in Fig. 1A. The lamp housing (four) is in a shape close to a half _ less than a semicircle, and the two are half-removed. And (10) there is an LED lamp 17 on the circuit board, and the back surface (refers to the concave platform μ in the lamp housing, the touch-face) is a metal plate to simplify (10) the circuit board is mounted on the lamp housing. 15 is bored through the hole i5a of the led circuit board 80 on the concave flat A ^ opposite lying lion hole 15b.减 个 赖 赖 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ The 4Q gap ❹ westward distribution) is shown in Figure 1A. Please also refer to the back view of the lamp on the back of Fig. 1 . In Fig. 1 , the fins 4 can be seen on the semicircular surface. The heat sink fins 4 are not equally sized in each of the preferred embodiments. ^ If 'it's a big 4 〇Α, a small staggered arrangement, please refer to Figure Μ, Figure and Figure 1 Ε. The large and small staggered fins 40 can make the distance between two adjacent large fins not appear crowded. In another embodiment, '匕 may also be two small heat sink fins 40B sandwiched between two adjacent large heat sink fins'. In another embodiment, it may also be two adjacent large The heat-dissipating fins 40A are sandwiched between - a medium heat sink and a small heat sink. The variation of the above embodiment is adjusted according to the distance between the two adjacent heat dissipation fins 40 and the south degree. That is to say, when the heat dissipating fins 40 are high and dense, the two adjacent large and small pieces of the bumps can have an improvement in the broadcast, and another advantage is that better heat convection is obtained. Another advantage of the above-described heat dissipating film 4 垂直 perpendicular to the axial direction of the tube is the provision of rain and the discharge of brittle edges. Compared with the conventional tube, the loose sheet is more parallel to the long axis, so that when it rains, the water will be more ruined. In addition, dust is likely to accumulate in the fins of the fins. In addition to affecting heat dissipation, sand dust has the disadvantage that the potential difference between the dust concealer area and the unshielded area is the same as that of the hot fin. This tube is scattered, 18 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Table 3 Bu-Intentional Concave Platform 18 The radiating fins 40 are perpendicular to the volume of the same person, the same dissipative and ambiguous: the other benefit of the distribution is that the heat-dissipating fins of the phase 4 〇 her Degree and interval, the new east-west distribution, the parallel _ line (that is, the long side of the lamp is no matter what is Xiao) ° large heat dissipation area means the way _ flow mode, compared to _ pl - In the case of A, the thickness of the heat-dissipating Korean film 40 is 〇. 2mm wide and 50 coffee, phase: 1m brewing's standing on the surface of a semi-cylindrical tube with a length of 300, but the thickness Q.2mra is arranged parallel to the area of the sheet. The heat dissipation fins of the long 3Gta are the same as the heat dissipation efficiency of 2. 8mm. The Newtonian heat convection cooling law Q~hA(T^ ~Tf) +., /, the medium force is the thermal convection coefficient 'thermal convection coefficient is not the physical property of the flow' but will be subject to the _ geometry, the more The influence of parameters such as current and the nature of the body. That is, the fluid is related to the laminar flow, or the vortex flow, where the fluid refers to air. Among them, the vortex heat can provide the best transmission and the transition flow. (4) Riding, the horizontal and vertical arrangement method of the new type of fins on the semi-cylindrical surface is formed on the surface of the semi-cylindrical surface in the same manner as the planar type, but in the form of a long strip, / for the outdoor Street lights, in the environment, the cold air at night can provide the heat convection required for street lighting. Therefore, the heavy load of the scale flow is more than the heat transfer, that is, how to reduce the airflow of the engine ship (4) and the convection of the heat sink fins. The above-mentioned heat dissipation of the present invention is 4G (including large and small heat-dissipating pieces): the small-sized heat dissipation of the bearing method reduces the heat-dissipating area, but it is easy to enter the heat-dissipating Korean film of the lamp tube 10, _. And make = :. In addition, the heat dissipation is 4Q, which is a kind of bat-like exhausting double-wing, and further the heat convection environment of the two cars. In particular, as shown in FIG. 1D, the heat-dissipating Korean film method 41 (the body between the wings) is low, so that the ambient gas 4 above the lamp tube can be dispersed into each of the heat-dissipating Korean films. The effect of heat convection. _According to the experimental results, the lamp of this surface can effectively reduce the temperature of the wafer in the middle of the field. Especially in the environment of Xu Feng, the temperature of the LED chip can be effectively reduced. Please refer to the experimental data in Table 1. 2.
