INSTRUCTIONS: ‘Technical Field to Which the Invention Alonged The present invention relates to a Li:D bulb', particularly to an innovative designer of its heat sink structure. [Prior Art] According to the fact that the bulb made by the LED (abbreviated as LED) has the advantages of power saving and durability compared with the conventional bulb, the market share has gradually increased. . However, in terms of the structural aspect of the LED bulb, in order to meet the demand for high brightness, the number of LEDs must be relatively increased, and when the number of LEDs reaches a regulation, it will generate relatively high heat when it is lit. The influence of the components on the use of life and safety, therefore, the design of the heat dissipation mechanism has become an essential and important structural part of the high-reliability LED bulb. In the design of the heat dissipation structure of the LED bulb, the simple one is set on a heat sink body, and a heat dissipation hole is formed on the peripheral side of the main body of the LED bulb to facilitate the heat out of the outside, but the heat dissipation structure Because it is a passive method, it cannot force and efficiently dissipate the heat absorbed by the heat sink body. Therefore, the heat dissipation efficiency is poor, and it is insufficient for the heat dissipation of high-brightness and high-efficiency LED bulbs. ^ Another kind of conventional LED bulb heat dissipation structure type is as shown in Figure i, which is added to the corresponding heat sink body 11 of the L fairy bulb 10 - the cooling fan 12 '俾y wrong is generated by the operation of the cooling fan 12 The air flow W is driven to force the word ', ', and the gas is discharged to the outer 邠'. The LED bulb 1 is provided with a vent hole 200920996 14 and an air inlet hole 15 at the circumferential side interval; however, the conventional LED bulb heat dissipation structure remains There are the following problems:
由於其散熱座體11供組設散熱風扇10之該側散熱面13 係設成平面態樣，因此，當該散熱風扇12旋轉運作時，被 散熱風扇12所推送之氣流W撞擊該散熱面13後，將產生側 向轉折且直接透過LED燈泡10周側所設排氣孔14排出外部 :然而，由於LED燈泡10周側所設之進氣孔15與前述排氣 孔14位置相當臨近（一般僅約3公分間距），因此，由排 氣孔14側向排出之熱氣流W將容易再度由進氣孔15吸入匕 ED燈泡10内，進而形成熱氣流w反復循環之現象，如此— 來，由於該散熱風扇10運作上難以導入冷空氣，勢必大幅 影響其散熱效益而造成效能不彰之缺憾。Since the heat dissipating body 11 is configured to planarize the side heat dissipating surface 13 of the heat dissipating fan 10, when the cooling fan 12 rotates, the airflow W pushed by the cooling fan 12 strikes the heat dissipating surface 13 After that, a lateral turn will be generated and directly discharged through the vent hole 14 provided on the circumferential side of the LED bulb 10; however, since the intake hole 15 provided on the circumferential side of the LED bulb 10 is relatively close to the vent hole 14 (generally Only about 3 cm spacing), therefore, the hot air flow W discharged laterally from the vent hole 14 will be easily inhaled into the 匕ED bulb 10 again by the air inlet hole 15, thereby forming a phenomenon in which the hot air flow w is repeatedly circulated, thus, Since the cooling fan 10 is difficult to introduce cold air in operation, it is bound to greatly affect the heat dissipation efficiency and cause a lack of performance.

LED bulb 1 〇 The assembled luminaire (when the LED bulb 10 is surrounded, it will cause the hot airflow W to be expelled and the hood is intensified), making its hot air more difficult: to solve the problems of the above-mentioned light bulbs, such as Developed a goal that can be more and more "innovative structure 1 to be considered by the relevant industry and then to think about breakthroughs.

[Invention content] 200920996 The main purpose of the present invention is to provide a heat sink for a led bulb. The problem to be solved is the problem that the heat dissipation fan of the conventional led bulb operates when the airflow hits the heat dissipating surface and then turns laterally and directly discharges through the exhaust hole to form a hot air circulation phenomenon, which greatly affects the heat dissipation benefit. Thinking about the breakthrough; the heat sink block is disposed inside the main body of the LED bulb and corresponding to the heat dissipation fan module, and the main body of the LE:D bulb is provided with a connection group, a module, a projection part and an electric control module; the heat sink comprises a heat sink body defining a heat conducting portion and a heat radiating portion, wherein the heat conducting portion is for combining the LED module, and the heat radiating portion is connected with the heat dissipating fan module Corresponding to the technical feature of the present invention to solve the problem, the main part is that the heat radiating portion is provided with a slanting guide flow surface, and the oblique guide flow surface is corresponding to the fan module; II innovative and unique design enables the present invention Compared with the prior art, the following advantages can be achieved: The heat sink has an oblique direction d, and the needle guide surface is not counted, so that the airflow passes through the political fan module and the oblique guide can be passed through The slope of the flow surface is guided to be inclined = the diameter of the row to allow the discharge airflow to be pinched away from the air intake hole, and there is a death M w 1 , and when the led bulb is surrounded by a cover shell, the oblique guide heat is used.
