Description
本發明係有關一種燈泡,更特別有關一種發光二極體燈泡。 The present invention relates to a light bulb, and more particularly to a light emitting diode bulb.
發光二極體由於具有低耗能、高效率之優點,目前正大力推廣用來做為照明用之光源。雖然發光二極體燈泡具有上述的優點,但是有散熱的問題必須解決。若無法有效地散熱,高溫會造成發光二極體的發光效率降低、壽命減少以及波長偏移等問題,甚至是燒毀發光二極體晶片。 Light-emitting diodes are currently being promoted as a light source for illumination because of their low energy consumption and high efficiency. Although the light-emitting diode bulb has the above advantages, the problem of heat dissipation must be solved. If the heat cannot be effectively dissipated, the high temperature may cause problems such as reduced luminous efficiency, reduced lifetime, and wavelength shift of the light-emitting diode, and even burning of the LED chip.
習知技術有在發光二極體燈泡的燈頭上裝設散熱鰭片,來將發光二極體燈泡在運作過程中所產生的熱量散逸。上述之散熱鰭片雖可將熱量散出,然而其體積龐大,外觀並不討喜。再者,裝設散熱鰭片會增加製造成本,也會使得燈泡的整體重量增加。 Conventional technology has a heat sink fin mounted on the base of the light-emitting diode bulb to dissipate the heat generated by the light-emitting diode bulb during operation. Although the heat dissipating fins described above can dissipate heat, their bulk is large and the appearance is not satisfactory. Furthermore, the provision of heat sink fins increases the manufacturing cost and also increases the overall weight of the bulb.
有鑑於此,便有需要提出一種方案,以解決上述問題。 In view of this, there is a need to propose a solution to solve the above problems.
