LED燈泡LED bulb

本創作係為一種LED燈泡,尤指一種藉由於一燈罩以及一底座之材質內混合有預設比例之複數個光擴散粒子,達到將該LED單元(Light Emitting Diodes)所投射之光線予以發散,且令該燈罩與底座均可達到發光的狀態。The present invention is an LED light bulb, in particular, a light diffusing particle that is mixed with a preset ratio by a lampshade and a base material, so that the light projected by the LED unit (Light Emitting Diodes) is diverged. Moreover, both the lamp cover and the base can be illuminated.

市面上各式各樣的燈泡中,投射燈長久以來一直佔了相當固定之比例。傳統的投射燈,係使用110伏特之鹵素投射燈泡,不但耗電量高,且容易發熱,相對的壽命也非常短,平均壽命只有幾個月,在這個電價高漲的年代,不僅非常不環保,且其所散發之高熱亦容易造成電線走火等危險意外。Among the various bulbs on the market, projection lamps have long been a fairly fixed proportion. The traditional projection lamp uses a 110 volt halogen projection bulb, which not only consumes high power, but also is prone to heat, and its relative life is very short. The average life expectancy is only a few months. In this era of high electricity prices, it is not only very environmentally friendly. And the high heat it emits is also likely to cause dangerous accidents such as wire fire.

因此,目前市面上符合MR-16規格之LED投射燈1均利用LED本身之低耗電量的特性來改善傳統鹵素投射燈泡之缺失。請參考圖一、圖二所示,圖一、圖二分別為習用LED投射燈之立體分解示意圖以及立體組合示意圖。習用之LED投射燈1係主要包括有:至少一LED單元11、一導熱柱12、一散熱模組13、至少一金屬基板14、至少一蓋體15、一護套16、一底座17、以及一電路板18所組合而成。該導熱柱12係為一筒狀,且包括有:一頂端121、以及一底端122,並於該頂端設有至少一貫穿孔 1211。Therefore, the LED projection lamp 1 currently conforming to the MR-16 specification on the market utilizes the low power consumption characteristics of the LED itself to improve the lack of the conventional halogen projection bulb. Please refer to FIG. 1 and FIG. 2 . FIG. 1 and FIG. 2 are respectively a three-dimensional exploded schematic view and a stereoscopic combination diagram of a conventional LED projection lamp. The conventional LED projection lamp 1 mainly includes at least one LED unit 11, a heat conducting column 12, a heat dissipation module 13, at least one metal substrate 14, at least one cover 15, a sheath 16, a base 17, and A circuit board 18 is combined. The heat conducting column 12 is cylindrical and includes a top end 121 and a bottom end 122, and is provided with at least a consistent perforation at the top end. 1211.

該散熱模組13係由複數個散熱鰭片131所組合,且靠合於該導熱柱12之外圍呈放射狀間隔環形串接,並以該護套16將該散熱鰭片131之外圈框圍。並於該散熱鰭片131靠合於該導熱柱12之該頂端121處往外擴張一凹階132。該LED單元11係結合於該金屬基板14之上,並固接於該凹階132上。The heat dissipation module 13 is composed of a plurality of heat dissipation fins 131, and is radially connected to the periphery of the heat conduction column 12 in a ring-shaped series, and the heat dissipation fins 131 are surrounded by the sheath 16 Wai. The concave fins 132 are outwardly expanded at the top end 121 of the heat conducting post 12 . The LED unit 11 is coupled to the metal substrate 14 and fixed to the concave step 132.

該蓋體15係覆蓋於該金屬基板14之上並位於該凹階132內。於該底座17上其具有一弧形開口,係與該導熱柱12之底端122所環繞之該散熱鰭片131相互固定,且可令該電路板18係設置於該底座17內。該電路板18透過該導熱柱12上之該貫穿孔1211與該金屬基板14上所結合之LED單元11做電性連接。The cover 15 covers the metal substrate 14 and is located in the concave step 132. The base 17 has an arc-shaped opening, which is fixed to the heat-dissipating fins 131 surrounded by the bottom end 122 of the heat-conducting column 12, and the circuit board 18 is disposed in the base 17. The circuit board 18 is electrically connected to the LED unit 11 coupled to the metal substrate 14 through the through hole 1211 of the heat conducting column 12 .

由於該LED投射燈1所產生之光束必須透過該蓋體15投射至外界,而該蓋體15則負責該LED投射燈1二次折射的功能,但習用之該蓋體15大都採單一透鏡為主,無法將光線加以勻光呈現,以致於使該LED投射燈1的亮度過高且集中,容易產生炫光刺眼現象,且由於該散熱鰭片131直接暴露於外側,容易於手持裝配該LED投射燈1時造成該散熱鰭片131之變形,以致於影響散熱效果;另外,由於該底座17係以容納該電路板18為主,而該底座17大多採不透光之材質所構成,且結合於該底座17上之該散熱鰭片131則完全暴露於空氣中,不僅容易招致外界灰塵的卡附,更容易因濕氣或雨水導致鏽蝕的現象,進一步可能使其內部之該電路板18遭到侵蝕破壞 而短路。Since the light beam generated by the LED projection lamp 1 must be projected to the outside through the cover 15, the cover 15 is responsible for the secondary refraction of the LED projection lamp 1, but the cover 15 is generally a single lens. Mainly, the light cannot be uniformly reflected, so that the brightness of the LED projection lamp 1 is too high and concentrated, and glare glare is easily generated, and since the heat dissipation fin 131 is directly exposed to the outside, it is easy to assemble the LED by hand. When the lamp 1 is projected, the heat dissipation fin 131 is deformed so as to affect the heat dissipation effect. In addition, since the base 17 is mainly for accommodating the circuit board 18, the base 17 is mostly made of a material that is opaque, and The heat dissipating fins 131 coupled to the base 17 are completely exposed to the air, which is not only easy to attract the external dust, but is more likely to be rusted by moisture or rain, and further may cause the circuit board 18 inside. Damaged by erosion And short circuit.

有鑑於此,為改良上述習用LED投射燈1之不足及缺失所造成之困擾,因此,創作人乃決定潛心研究並加以改進所提出之LED燈泡,來加以改善習用LED投射燈1所產生缺失及困擾,經不斷的反覆測試與實驗、研究與改進,並綜集多年相關產品行銷經驗之所得,終於研創出本創作之LED燈泡,不僅進一步將LED單元之所折射之光線予以均勻化呈現,使光線亮度更趨於柔和,且設置於後方之底座亦可同時發光,其外型更加美觀並兼具保護電路以及散熱鰭片之效果,且進一步減少零件以及製程步驟,達到降低成本的目的。In view of the above, in order to improve the troubles caused by the shortage and lack of the conventional LED projection lamp 1, the creator decided to study and improve the proposed LED bulb to improve the defect of the conventional LED projection lamp 1. Troubled, after repeated repeated tests and experiments, research and improvement, and the collection of years of relevant product marketing experience, finally developed the LED bulb of this creation, not only further uniformizing the light reflected by the LED unit, so that The brightness of the light is softer, and the base disposed at the rear can also emit light at the same time.
