Description
本創作係有關一種發光二極體球泡燈,特別是一種具有全週光分佈效果之全週型發光二極體球泡燈。The present invention relates to a light-emitting diode bulb, in particular to a full-circumferential light-emitting diode bulb having a full-circumferential distribution effect.
由於發光二極體(LED)具備省電、使用壽命長及不含汞等有毒物質的優點,使得LED球泡燈逐漸受到使用者的青睞。然LED球泡燈常會因其散熱問題而導致電路基板損壞或者是LED損壞,因此為了使LED球泡燈可長時間運用並維持一定亮度,LED球泡燈需設置有散熱裝置以將LED發光時所產生的熱能適當排出至外界。Because LEDs have the advantages of power saving, long service life and no toxic substances such as mercury, LED bulbs are gradually favored by users. However, LED bulbs often cause damage to the circuit board or LED damage due to heat dissipation problems. Therefore, in order to enable the LED bulb to be used for a long time and maintain a certain brightness, the LED bulb needs to be provided with a heat sink to illuminate the LED. The generated heat is properly discharged to the outside world.
一般LED球泡燈主要包含LED模組及散熱結構,散熱結構組設於LED模組下方,以透過散熱結構將LED模組所產生之熱能散出,圖1所示為習知一種LED球泡燈之散熱結構示意圖,如圖1所示,散熱結構10包含複數金屬鰭片12,各金屬鰭片12以扣接串聯方式呈環狀等間隔排列,並利用鋁膏、錫膏或接著劑予以膠合,之後再對金屬鰭片12進行陽極處理;又LED模組之電路基板(圖中未示)係以導熱膠固定於金屬鰭片12之頂緣121,以便經由電路基板與金屬鰭片12的接觸使LED模組所產生之熱能傳導至金屬鰭片12,且藉由各金屬鰭片12間之空隙供空氣流動,以將熱能散出。The general LED bulb mainly comprises an LED module and a heat dissipation structure, and the heat dissipation structure is disposed under the LED module to dissipate the heat energy generated by the LED module through the heat dissipation structure. FIG. 1 shows a conventional LED bulb. Schematic diagram of the heat dissipation structure of the lamp. As shown in FIG. 1 , the heat dissipation structure 10 includes a plurality of metal fins 12 , and the metal fins 12 are arranged in a ring at equal intervals in a snap-fit manner and are coated with an aluminum paste, a solder paste or an adhesive. Gluing, and then anodizing the metal fins 12; the circuit board (not shown) of the LED module is fixed to the top edge 121 of the metal fin 12 by a thermal conductive adhesive so as to pass through the circuit substrate and the metal fins 12 The contact causes the thermal energy generated by the LED module to be conducted to the metal fins 12, and the air flows through the gaps between the metal fins 12 to dissipate the heat energy.
在上述LED球泡燈之散熱結構10中,當應用於具有高瓦數之LED模組時,溫度容易集中於金屬鰭片12之外緣122,無法用手直接碰觸,使用上較為危險。同時金屬鰭片12表面也容易因金屬導電而有安全顧慮或電磁波干擾等問題。又金屬鰭片12原本銳利的外緣122雖然已經陽極處理或各種塗料的噴塗處理,但仍然無法避免手部割傷上的安全問題。In the heat dissipation structure 10 of the LED bulb described above, when applied to an LED module having a high wattage, the temperature is easily concentrated on the outer edge 122 of the metal fin 12, and it is not directly touched by the hand, which is dangerous in use. At the same time, the surface of the metal fin 12 is also prone to safety concerns or electromagnetic interference due to metal conduction. Moreover, the original sharp outer edge 122 of the metal fin 12 has been anodized or sprayed with various paints, but the safety problem of hand cuts cannot be avoided.
另一方面,習知LED球泡燈之LED模組受限於結構的設計,發光角度受到限制,只能有半週型,亦即低於180度的發光角度,使整個LED球泡燈發光角度窄且發光強度不均勻。On the other hand, the LED module of the conventional LED bulb is limited by the design of the structure, and the illumination angle is limited, and only the half-cycle type, that is, the illumination angle lower than 180 degrees, enables the entire LED bulb to emit light. The angle is narrow and the luminous intensity is not uniform.
為了解決上述問題,本創作目的之一係提供一種全週型發光二極體球泡燈,其發光角度增寬,且發光強度均勻,而呈一全週光分佈,可改善習知發光二極體球泡燈因LED的光源直向性問題所導致之狹窄發光角度及發光強度不均勻的缺失。In order to solve the above problems, one of the purposes of the present invention is to provide a full-circumference type light-emitting diode bulb, which has a wide illumination angle and uniform luminous intensity, and exhibits a full-circumferential distribution, which can improve the conventional light-emitting diode. The body bulb has a narrow illumination angle and a lack of uneven illumination intensity due to the directivity problem of the LED light source.
