Description
本發明係關於一種高功率之照明燈具；特別是指具有熱管以提高燈具之散熱效率者。 The present invention relates to a high power lighting fixture; in particular, to a heat pipe to improve the heat dissipation efficiency of the lamp.
LED已被廣泛地應用於各種場所之照明燈具上，然而，對於大功率之燈具，例如漁船之集魚燈、大型球場之球場燈、舞台燈、礦場燈……等，係使用高功率之LED燈，其單位發光的亮度大，但相對地，高功率之LED燈在運作時會產生大量的熱量，使得燈具的外殼或LED燈的燈座因受到高溫而熔毀，或使高功率LED燈因高熱而損壞，導致LED燈組故障而無法發亮的問題。習知的LED燈由於散熱能力不足，導致大功率之燈具在發展上備受限制。而部分LED燈為了要裝設散熱模組，往往使得組裝過程變的複雜，影響產能，確實有加以改良的必要。 LED has been widely used in lighting fixtures in various places. However, for high-power lamps, such as fishing boats, fishing boats, stadium lights, stage lights, mine lights, etc., high-power LEDs are used. The brightness of the unit light is large, but relatively, the high-power LED lamp generates a large amount of heat during operation, so that the lamp housing or the lamp holder of the LED lamp is melted due to high temperature, or the high-power LED lamp is made. Damage caused by high heat, causing the LED light unit to malfunction and fail to illuminate. Conventional LED lamps are limited in their development due to insufficient heat dissipation capability. In order to install a heat dissipation module, some LED lamps often make the assembly process complicated and affect the production capacity, and it is necessary to improve it.
為了解決高功率燈具的散熱問題，習知有以熱管輔助燈具傳導熱量以提高散熱效率者，例如請參閱我國發明專利證書號第I403675號「燈具散熱裝置」以及我國發明專利證書號第I414717號「高散熱之發光二極體模組及發光二極體燈具」者，其均係利用熱管之快速均溫導熱的特性將燈具產 生的熱快速帶離燈具，並於熱管上裝設鰭片以協助散熱。 In order to solve the heat dissipation problem of high-power lamps, it is known to use heat pipe-assisted lamps to conduct heat to improve heat dissipation efficiency. For example, please refer to China Invention Patent No. I403675 "Lamp Heat Dissipation Device" and China Invention Patent No. I414717" The high-heat-emitting LED module and the light-emitting diode lamp are all made by the characteristics of the rapid temperature-dependent heat conduction of the heat pipe. The raw heat is quickly taken away from the luminaire, and fins are placed on the heat pipe to assist in heat dissipation.
然而，具有熱管以協助導熱或散熱的燈具大多係將熱管直接裝設於燈具上，藉由熱管與燈具之壁面直接接觸以傳遞熱能，但是兩種金屬混合接觸時會降低導熱效率，造成導熱不均，因此，習知的燈具在導熱的均勻度及散熱效率方面，仍有可改善的空間。 However, most of the lamps with heat pipes to assist heat conduction or heat dissipation are directly installed on the lamps, and the heat pipes are directly in contact with the wall surface of the lamps to transfer heat energy, but the two metals are mixed to reduce the heat conduction efficiency, resulting in no heat conduction. Therefore, the conventional luminaire still has room for improvement in terms of heat conduction uniformity and heat dissipation efficiency.
有鑑於此，本發明人潛心構思並更深入研究，終於發明出一種流體冷卻式燈具。 In view of this, the inventors have conceived and studied more deeply, and finally invented a fluid-cooled luminaire.

The main purpose of the luminaire is to make the heat conduction between the lamp and the heat pipe average, and to improve the heat conduction efficiency between the lamp and the heat pipe, thereby improving the heat dissipation efficiency of the lamp.
