200923251 九、發明說明： 【發明所屬之技術領域】 本發明是有關於一種燈具，特別是有關於一種應用交 流發光二極體之燈具。 【先前技術】 一般來說，目前大部份的燈具是應用直流發光二極體 (DCLED)來做為光源。然而，由於一般民生用電皆是以交 流電來做為供電源，故燈具還必須搭配變壓器來將交流電 轉換為直流電，以供直流發光二極體進行發光運作。如上 所述，當燈具應用交流電來發光時，其需要經過兩次能量 轉換。第一次能量轉換是變壓器將交流電轉換為直流電， 而第二次能量轉換是直流發光二極體將直流電能轉換為光 能。大體而言，第一次能量轉換的能量轉換效率較低並損 耗許多電能，因而會使得直流發光二極體或燈具的發光效 率無法被提升。因此，第一次能量轉換相較於第二次能量 轉換會產生較多的熱量。 此外，在美國專利公開第2002/0117376號中揭露有一 種應用直流發光二極體做為光源之精油蒸發器（essential oil evaporator)。在此，直流發光二極體的熱量主要是在第 一次能量轉換中產生，並分佈於變壓器之上，而晶片上累 積之熱量並不足以加熱或蒸發精油。因此，在此專利中， 直流發光二極體僅用於裝飾或照明。精油乃是以一額外的 加熱裝置來加熱蒸發。 有鑑於此，本發明之目的是要提供一種具有光源之燈 200923251 具，其可產生足夠的熱量以蒸發精油。 【發明内容】 本發明基本上採用如下所詳述之特徵以為了要解決上 述之問題。也就是說，本發明提供一種燈具，包括燈體、 交流發光二極體以及插頭。交流發光二極體設置於燈體之 上。插頭電性連接於交流發光二極體。燈具可包括設置於 燈體之上的容器。容器可容納液體。液體可為水或是精油。 精油用於蒸發，水用於散熱。液體為透明或半透明，因此 交流發光二極體所提供的光線可通過液體。交流發光二極 體可鄰接於容器，因而交流發光二極體所產生之熱量可經 由容器加熱及蒸發液體。容器可由導熱材料所製成，具有 盛杯及杯蓋，盛杯係設置於燈體之上，杯蓋係設置於盛杯 之上。杯蓋實質上可為透明或半透明。燈體具有導熱表面， 導熱表面連接於交流發光二極體，且鄰接於容器，以及交 流發光二極體所產生之熱量係經由導熱表面而傳遞至容 器，以加熱及蒸發液體。插頭係相對於導熱表面。插頭係 為歐規插頭。燈具可包括加熱調變控制器，電性連接於交 流發光二極體，用以控制交流發光二極體之發光強度以及 液體之蒸發速率。燈具可包括溫度過載保護電路，電性連 接於交流發光二極體。燈具可包括燈罩，包覆交流發光二 極體。燈罩是透明的或半透明的。燈罩係成形有花紋圖案， 以及花紋圖案藉由交流發光二極體所發出之光線而投射至 燈罩之外部。燈具更包括計時器，鄰接於交流發光二極體， 其中，計時器所顯示之時間係藉由交流發光二極體所發出 7 200923251 之光線而投射至燈體之外部。燈具更包括反射器，鄰接於 交流發光二極體，用以反射交流發光二極體所發出之光 線。反射器係以轉動之方式連接於燈體。 本發明之另一實施例提供一種燈具，包括底座、支撐 架、燈體以及交流發光二極體。支撐架具有第一端部及第 二端部，其中，第一端部係相對於第二端部，並且係連接 於底座。燈體連接於支撐架之第二端部。交流發光二極體 設置於燈體之上。支撐架之第一端部以轉動之方式連接於 底座。燈體以轉動之方式連接於支撐架之第二端部。支撐 架由金屬製成，且其所產生的熱量係由支撐架、底座的金 屬外殼以及燈體進行散熱。 本發明之另一實施例提供一種燈具，包括底座、支撐 架、燈體以及交流發光二極體。支撐架以轉動之方式連接 於底座。燈體連接於支撐架。交流發光二極體設置於燈體 之上。支撐架係由金屬製成，且其所產生的熱量係由支撐 架、底座的金屬外殼以及燈體進行散熱。 本發明之另一實施例提供一種燈具，包括交流發光二 極體以及水層，環繞於交流發光二極體以進行散熱。 為使本發明之上述目的、特徵和優點能更明顯易懂， 下文特舉較佳實施例並配合所附圖式做詳細說明。 【實施方式】 茲配合圖式說明本發明之較佳實施例。 相較於傳統應用直流發光二極體的燈具，其所產生的 熱量散佈於晶片以及外部變壓器之上。在應用交流發光二 200923251 極體的燈具中，其所產生的熱量幾乎都集中於晶片之上， 由於交流發光二極體直接運用交流電源提供能量，免去了 變壓器以及變壓過程中的能量損失。因此，交流發光二極 體之晶片上所累積的熱量將足以蒸發精油。在另一實施例 中，本發明應用一低阻抗純水環繞該交流發光二極體以對 其進行散熱。在另一實施例中，本發明利用一金屬製的支 撐架以進行散熱。 第一實施例 請參閱第1圖，本實施例之燈具101可以做為一精油 蒸發器，並且其主要包括有一燈體110、一交流發光二極 體120、一插頭130、一容器140、一加熱調變控制器150 及一溫度過載保護電路160。 燈體110具有一導熱表面111。 交流發光二極體120是設置於燈體110之上。更詳細 的來說，交流發光二極體120乃是設置於燈體110之導熱 表面111之上。在一較佳實施例中，交流發光二極體120 乃是直接設置於燈體110之導熱表面111之上。 插頭130電性連接於交流發光二極體120。在本實施 例之中，插頭130是與燈體110整合在一起，並且插頭130 是設置於燈體Π0之導熱表面111之相對表面上。此外， 插頭13 0可以是一歐規插頭。 容器140是設置於燈體110之上，並且容器140可容 納有一液體（例如，精油或水）。更詳細的來說，容器140 的材質為導熱材料，並且容器140具有一盛杯141及一杯 200923251 蓋142。盛杯⑷是設置於燈體n〇之上，以承载精油或 水。杯蓋142是設置於盛杯141之上，並且杯蓋142每所 上是透明的或半透明的。值得注意的是，交流發光二=

於蒸發精油的加熱手段可不止一顆交流發光二極體。即， 一燈具101可選擇具有多個交流發光二極體環繞或鄰近容 益14 0 (之盛杯141)以達到相同的加熱功能。在另一方面’ 燈體110之導熱表面111是直接抵接交流發光二極體 120。導熱表面111是鄰近於容器140(之盛杯141)，特別 是，導熱表面111是連接或直接抵接於容器140(之盛杯 141)，交流發光二極體120所產生之熱量會經由導熱表面 111而傳遞至容器140(之盛杯141)，以加熱及蒸發精油。 如上所述，由於容器140之杯蓋142實質上是透明或 半透明的，故可以目視方式輕易得知盛杯141中之精油的 殘留罝^並據以決定是否需對盛杯141補充精油。 此外，燈具101可藉由加熱調變控制器150來提供不 同的發光或加熱模式。也就是說，加熱調變控制器150可 用來控制交流發光二極體120之發光強度以及精油之蒸發 速率。舉例來說，當使用者欲處於休息狀態時，其可以加 熱調變控制器150來降低交流發光二極體120之發光強 度。此時，交流發光二極體120所產生之熱量亦會隨之降 低，因而可同時達成暗光以及精油氣味不致於過重等效 果。反之，當使用者處於工作狀態時，其可以加熱調變控 制器150來提高交流發光二極體120之發光強度。同時， 交流發光二極體120所產生之熱量亦會隨之提高，因而可 加快精油之蒸發速度，進而達到提振精神的效果。 再者’當盛杯141中之精油的溫度過南時’電性連接 11 200923251 於插頭130與交流發光二極體120之間的溫度過載保護電 路160即會切斷供應至交流發光二極體120之交流電源， 以防止整個燈具101因精油溫度過高而發生損壞危險。 第二實施例 在本實施例中，與第一實施例相同之元件均標示以相 同之符號。 請參閱第2圖，本實施例之燈具102主要包括有一燈 體110、一交流發光二極體120、一插頭130及一燈罩170。 燈罩170是包覆著交流發光二極體120。在一較佳的 實施例中，燈罩170可與燈體110相接。此外，燈罩170 可以是透明或半透明的，以讓交流發光二極體120所發出 之光線部份或全部穿透。在本實施例之中，燈罩170上可 有至少一花紋圖案171。 至於本實施例之其他元件構造、特徵或運作方式均與 第一實施例相同，故為了使本案之說明書内容能更清晰易 懂起見，在此省略其重複之說明。 當燈具102之插頭130插接於一交流電源插座時，燈 罩170上之花紋圖案171會藉由交流發光二極體120所發 出之光線而投射至燈罩170之外部。舉例來說，燈罩170 上之花紋圖案171可藉由交流發光二極體120之照射而投 射至一牆壁上，因而可達成裝飾效果。 第三實施例

第一實施例相同，故為了使本案之說明書内容能更清晰易 懂起見，在此省略其重複之說明。 第五實施例 請參閱第5圖，本實施例之燈具500主要包括有一底 座510、一支撐架520、一燈體530、多個交流發光二極體 540及一電源插頭550。 支撐架520具有一第一端部521及一第二端部522。 第一端部521是相對於第二端部522。支撐架520是藉由 第一端部521而以轉動之方式連接於底座510。 燈體530是以轉動之方式連接於支撐架520之第二端 部522。因此，燈體530與支撐架520之間的角度可以調 整，進而可調整交流發光二極體540之照明角度及區域。 在燈體530之上設置有多個交流發光二極體540，交 流發光二極體540與電源插頭550電性連接。更詳細的來 說，電源插頭550乃是藉由一電源線S而電性連接於交流 發光二極體540。 如上所述，當燈具500之電源插頭550插接於一交流 電源插座（未顯示）時，交流發光二極體540即會提供照明 用之光線。此外，藉由調整燈體530與支撐架520之間的 相對轉動位置及/或支撐架520與底座510之間的相對轉動 位置，交流發光二極體540所發出之照明光線的方向即可 被調整。另外，藉由同時調整燈體530與支撐架520之間 的相對轉動位置及支撐架520與底座510之間的相對轉動 位置，即可達成收疊燈具500之目的。 14 200923251 第六實施例 請參閱第6圖，本實施例之燈具600主要包括有一底 座610、一支撐架620、一燈體630以及多個交流發光二極 體 640。 支撐架620連接於底座610。 該燈體630係以可轉動的方式連接該支撐架620。因 此，該燈體630與該支撐架620之間的角度可以被調整， 以調整交流發光二極體640的照射角度以及照射區域。 在燈體630之上設置有多個交流發光二極體640，藉

INSTRUCTIONS: TECHNICAL FIELD The present invention relates to a luminaire, and more particularly to a luminaire to which an AC illuminating diode is applied. [Prior Art] In general, most of the current lamps use a DC LED as a light source. However, since the electricity used for ordinary people's livelihood is powered by AC power, the lamp must also be equipped with a transformer to convert the AC power into DC power for the DC light-emitting diode to perform the light-emitting operation. As mentioned above, when the luminaire uses alternating current to illuminate, it requires two energy conversions. The first energy conversion is a transformer that converts alternating current to direct current, and the second energy conversion is a direct current light emitting diode that converts direct current electrical energy into light energy. In general, the energy conversion efficiency of the first energy conversion is low and consumes a lot of electrical energy, so that the luminous efficiency of the DC light-emitting diode or the luminaire cannot be improved. Therefore, the first energy conversion produces more heat than the second energy conversion. Further, an essential oil evaporator using a direct current light-emitting diode as a light source is disclosed in U.S. Patent Publication No. 2002/0117376. Here, the heat of the DC light-emitting diode is mainly generated in the first energy conversion and distributed on the transformer, and the accumulated heat on the wafer is not enough to heat or evaporate the essential oil. Therefore, in this patent, the direct current LED is used only for decoration or illumination. The essential oil is heated and evaporated by an additional heating device. In view of the above, it is an object of the present invention to provide a light source lamp 200923251 which generates sufficient heat to evaporate essential oil. SUMMARY OF THE INVENTION The present invention basically employs the features detailed below in order to solve the above problems. That is, the present invention provides a light fixture including a lamp body, an alternating current light emitting diode, and a plug. The alternating current LED is disposed on the lamp body. The plug is electrically connected to the alternating current LED. The luminaire can include a container disposed over the body of the lamp. The container can hold a liquid. The liquid can be water or an essential oil. Essential oils are used for evaporation and water is used for heat dissipation. The liquid is transparent or translucent so that the light provided by the AC LED can pass through the liquid. The alternating current LED can be adjacent to the container so that the heat generated by the alternating current LED can be heated and vaporized by the container. The container may be made of a heat conductive material having a cup and a lid, the cup being disposed above the lamp body, and the cup lid being disposed on the cup. The lid can be substantially transparent or translucent. The lamp body has a thermally conductive surface, the thermally conductive surface is coupled to the alternating current light emitting diode, and adjacent to the container, and the heat generated by the alternating light emitting diode is transferred to the container via the thermally conductive surface to heat and evaporate the liquid. The plug is relative to the thermally conductive surface. The plug is a European standard plug. The luminaire may include a heating modulation controller electrically connected to the AC illuminating diode for controlling the illuminating intensity of the AC illuminating diode and the evaporation rate of the liquid. The luminaire may include a temperature overload protection circuit electrically connected to the AC illuminator. The luminaire can include a light cover that encloses the alternating current LED. The lampshade is transparent or translucent. The lampshade is formed with a pattern, and the pattern is projected to the outside of the lampshade by the light emitted by the AC light-emitting diode. The luminaire further includes a timer adjacent to the illuminating diode, wherein the time displayed by the timer is projected to the outside of the lamp body by the light of the 200923251 emitted by the ac diode. The luminaire further includes a reflector adjacent to the alternating current illuminating diode for reflecting the light emitted by the alternating current illuminating diode. The reflector is coupled to the lamp body in a rotational manner. Another embodiment of the present invention provides a light fixture including a base, a support frame, a lamp body, and an alternating current light emitting diode. The support frame has a first end and a second end, wherein the first end is opposite the second end and is coupled to the base. The lamp body is coupled to the second end of the support frame. The alternating current LED is disposed above the lamp body. The first end of the support frame is rotatably coupled to the base. The lamp body is rotatably coupled to the second end of the support frame. The support frame is made of metal and the heat generated by it is dissipated by the support frame, the metal casing of the base, and the lamp body. Another embodiment of the present invention provides a light fixture including a base, a support frame, a lamp body, and an alternating current light emitting diode. The support frame is coupled to the base in a rotational manner. The lamp body is connected to the support frame. The alternating current LED is disposed above the lamp body. The support frame is made of metal, and the heat generated by it is dissipated by the support frame, the metal case of the base, and the lamp body. Another embodiment of the present invention provides a light fixture comprising an alternating current light emitting diode and a water layer surrounding the alternating current light emitting diode for heat dissipation. The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims. [Embodiment] A preferred embodiment of the present invention will be described with reference to the drawings. Compared to conventional luminaires that use DC illuminators, the heat generated is spread over the wafer and external transformers. In the luminaires that use AC illuminator II 200923251, the heat generated by them is almost concentrated on the wafer. Since the AC illuminator directly uses AC power to provide energy, the transformer and the energy loss during the transformer process are eliminated. . Therefore, the heat accumulated on the wafer of the alternating current diode will be sufficient to evaporate the essential oil. In another embodiment, the present invention applies a low impedance pure water surrounding the ac diode to dissipate heat. In another embodiment, the present invention utilizes a metal support for heat dissipation. For the first embodiment, please refer to FIG. 1 . The lamp 101 of the present embodiment can be used as an essential oil evaporator, and mainly includes a lamp body 110 , an AC light emitting diode 120 , a plug 130 , a container 140 , and a The modulation controller 150 and a temperature overload protection circuit 160 are heated. The lamp body 110 has a heat conducting surface 111. The AC LED 120 is disposed on the lamp body 110. In more detail, the AC LED 120 is disposed on the heat conducting surface 111 of the lamp body 110. In a preferred embodiment, the AC LED 120 is disposed directly on the heat conducting surface 111 of the lamp body 110. The plug 130 is electrically connected to the AC LED 120. In the present embodiment, the plug 130 is integrated with the lamp body 110, and the plug 130 is disposed on the opposite surface of the heat conducting surface 111 of the lamp body Π0. In addition, the plug 130 can be a European plug. The container 140 is disposed above the lamp body 110, and the container 140 can accommodate a liquid (e.g., essential oil or water). In more detail, the container 140 is made of a thermally conductive material, and the container 140 has a cup 141 and a cup of 200923251 cover 142. The cup (4) is placed above the lamp body n〇 to carry essential oil or water. The lid 142 is disposed over the cup 141 and the lid 142 is transparent or translucent in each case. It is worth noting that the alternating light illuminator = 120 is adjacent to the container 14 之 (the cup 141), or / and the lamp body 〖 ο _ the heat conducting surface ill is adjacent to the container 14 〇 (the cup 141). The heating modulation controller 150 is electrically connected to the alternating current 120. In the present embodiment, the surface of the modulation control 110 is heated. The lamp body temperature overload protection circuit 16G is electrically connected between the light emitting diodes 120. 30, and turbulence, as described above, when the plug 13 of the lamp 101 is plugged into a socket (not shown), the AC LED 12 〇 & the power source cup m and the essential oil therein are transparent Or translucent:: and fever. The light emitted by the photodiode 120 can penetrate the cup 141 to prevent the heat generated by the alternating current and the alternating current diode (4) and =, and the fine of 141. Compared to the DC LED, the AC=120 has no transformer, so 'AC LED 12:: Paint: The polar body is concentrated on its wafer' so it accumulates in the AC LED = heat The heat on the wafer is much larger than the heat deposited on the DC light-emitting diode. Therefore, the alternating current LED 12G can evaporate the essential oil. = On the general case, the DC LED chip is not used, the heating method of the essential oil. In more detail, when the alternating current illumination is not adjacent to the container 140 (the cup 141) and the container 14 is formed by the anvil 12, the alternating current LED 120 generates the thermal backup. The prepared crucible 4 is heated and evaporated by the container 10 200923251 140 (the cup 141). In another embodiment, the heating means for evaporating the essential oil may have more than one alternating current LED. That is, a luminaire 101 can optionally have a plurality of ac diodes surrounding or adjacent to the susceptor 140 (the cup 141) to achieve the same heating function. On the other hand, the heat conducting surface 111 of the lamp body 110 directly abuts the alternating current light emitting diode 120. The heat conducting surface 111 is adjacent to the container 140 (the cup 141). In particular, the heat conducting surface 111 is connected or directly abuts the container 140 (the cup 141), and the heat generated by the AC LED 120 is transmitted through the heat conduction. The surface 111 is transferred to the container 140 (the cup 141) to heat and evaporate the essential oil. As described above, since the cup lid 142 of the container 140 is substantially transparent or translucent, the residual oil of the essential oil in the cup 141 can be easily visually recognized and it is determined whether or not the cup 141 needs to be replenished with the essential oil. Additionally, the luminaire 101 can provide different illumination or heating modes by heating the modulation controller 150. That is, the heating modulation controller 150 can be used to control the luminous intensity of the alternating current LED 120 and the evaporation rate of the essential oil. For example, when the user wants to be at rest, he can heat the modulation controller 150 to reduce the illumination intensity of the AC LED 120. At this time, the heat generated by the AC LED 120 is also lowered, so that the dark light and the essential oil odor are not excessively equivalent. On the contrary, when the user is in the working state, it can heat the modulation controller 150 to increase the luminous intensity of the alternating current LED 120. At the same time, the heat generated by the AC LED 120 is also increased, so that the evaporation speed of the essential oil can be accelerated, thereby achieving the effect of boosting the spirit. Furthermore, 'When the temperature of the essential oil in the cup 141 is over the south, the electrical connection 11 200923251 between the plug 130 and the AC LED 120 is cut off and supplied to the AC LED. 120 AC power supply to prevent the entire lamp 101 from being damaged due to excessive temperature of the essential oil.
