本發明是有關於一種散熱裝置，特別是指一種燈具散熱裝置。 The invention relates to a heat dissipation device, in particular to a lamp heat dissipation device.

參閱圖1，聚光燈在照射強大光源的同時，也產生了許多的熱能，熱能如沒有好好處理，將可能導致元件加速老化，進而影響使用壽命。而現有之一燈具散熱裝置9，包含一連接該燈具8的基板91，及多個由該基板91彼此平行且相間隔而向上延伸的散熱鰭片92。該燈具8所產生的熱能將通過該基板91向上傳導至該等散熱鰭片92而散發至空氣中，如環境中有空氣流動，則更能增加散發熱能的效率。 Referring to Fig. 1, the spotlight generates a lot of heat energy while irradiating a powerful light source. If the heat energy is not properly handled, it may cause accelerated aging of the components, which may affect the service life. An existing lamp heat dissipation device 9 includes a substrate 91 connected to the lamp 8 and a plurality of heat dissipation fins 92 extending parallel to and spaced from each other by the substrate 91. The heat energy generated by the lamp 8 will be conducted upward through the base plate 91 to the heat dissipation fins 92 and be radiated into the air. If there is air flowing in the environment, the efficiency of dissipating heat energy can be increased.

現有之該燈具散熱裝置9確實能藉由該等散熱鰭片92，提升散熱的表面積來達成散熱的效果，然而，在不更改該散熱裝置的外型為前提下，為了更大的亮度，便需要功率更強的燈具8，也連帶造成需要散除的熱能增加。換句話說，該實施例無法幫助該燈具8提供更好的照明效果，還可能需要對應更高功率的燈具8來進行結構上的改進。 The existing heat dissipation device 9 of the lamp can indeed increase the surface area of the heat dissipation through the heat dissipation fins 92 to achieve the effect of heat dissipation. However, without changing the appearance of the heat dissipation device, for greater brightness, The need for more powerful lamps 8 also increases the heat energy that needs to be dissipated. In other words, this embodiment cannot help the luminaire 8 to provide better lighting effects, and may also require a luminaire 8 corresponding to a higher power to enter Improvements in line structure.

因此，本發明之目的，即在提供一種幫助改善照明效果的燈具散熱裝置。 Therefore, the object of the present invention is to provide a heat dissipation device for a lamp that helps to improve the lighting effect.

於是，本發明燈具散熱裝置，包含一適用於供該燈具設置的聚光單元，及一連接該聚光單元的散熱單元。 Therefore, the heat dissipating device of the lamp of the present invention includes a light condensing unit suitable for the lamp and a heat dissipating unit connected to the light condensing unit.

該聚光單元包括一適用於供該燈具設置的承載件，及二彼此相間隔地分別由該承載件兩側斜向往外延伸的延伸件。其中，每一延伸件具有一鄰近該承載件並適用於反射光能的反射面。 The condensing unit includes a carrier suitable for the lamp, and two extensions extending diagonally outward from both sides of the carrier at intervals. Each extension member has a reflective surface adjacent to the carrier member and adapted to reflect light energy.

該散熱單元包括多個由該等延伸件彼此間隔且以遠離該燈具的方向往外延伸的鰭片件。 The heat dissipation unit includes a plurality of fin members spaced apart from each other by the extension members and extending outward in a direction away from the lamp.

本發明之功效在於：只要將該燈具設置於該等反射面之間，當該燈具通電發光並產生熱能時，發出的光線照射於該等反射面並被反射而產生聚光效果；熱能則會經由該等延伸件傳導至該鰭片件，進而與空氣進行熱交換，達成改善照明效果且優化散熱的功效。 The effect of the present invention is as follows: as long as the lamp is placed between the reflective surfaces, when the lamp is energized to emit light and generate thermal energy, the emitted light irradiates the reflective surfaces and is reflected to produce a light-gathering effect; thermal energy will Conducted to the fins through the extensions, and then exchange heat with the air, to achieve improved lighting effects and optimize heat dissipation.

在本發明被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。 Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

參閱圖2，本發明燈具散熱裝置之一第一實施例，包含一適用於供該燈具L設置的聚光單元1，及一個一體連接該聚光單元1的散熱單元2。 Referring to FIG. 2, a first embodiment of a heat dissipation device for a lamp of the present invention includes a light condensing unit 1 suitable for the lamp L and a heat dissipation unit 2 integrally connected to the light condensing unit 1.

該聚光單元1包括一適用於供該燈具L設置的承載件11，及二分別由該承載件11兩側彼此相間隔地斜向往外延伸的延伸件12，該等延伸件12鄰近於該承載件11之一側與該承載件11相配合形成一適用於供氣流通過之導流通道13。其中，該承載件11具有一呈貫穿狀的通風孔111；每一延伸件12具有一鄰近該承載件11且較佳是呈鏡面而能反射光線的反射面121，及一用以供該散熱單元2設置的散熱面122。值得一提的是，在製造上該等延伸件12之夾角大小可視使用者的需求進行改變，當需要較強烈而聚集的光束時，可將該夾角縮小；當需要較分散的光照時，則可將該夾角增大。 The condensing unit 1 includes a carrier 11 suitable for the lamp L, and two extensions 12 extending diagonally outward from the two sides of the carrier 11 and spaced apart from each other, the extensions 12 are adjacent to the One side of the bearing member 11 cooperates with the bearing member 11 to form a guide channel 13 suitable for air flow. Wherein, the supporting member 11 has a through-hole 111; each extending member 12 has a reflecting surface 121 adjacent to the supporting member 11 and preferably a mirror surface capable of reflecting light, and a heat dissipation surface The heat dissipation surface 122 provided by the unit 2. It is worth mentioning that the angle of the extensions 12 can be changed according to the user's needs during manufacturing. When a strong and concentrated light beam is needed, the angle can be reduced; when more scattered light is required, then The angle can be increased.

該散熱單元2包括多個由該等延伸件12彼此間隔且以遠離該燈具L的方向往外延伸的鰭片件21。需要特別說明的是，該聚光單元1及該散熱單元2應具備優異的散熱性，以及良好的結構強度，故較佳為銅、鋁的其中之一或其合金。 The heat dissipation unit 2 includes a plurality of fin members 21 spaced apart from each other by the extension members 12 and extending outward in a direction away from the lamp L. In particular, the light-concentrating unit 1 and the heat-dissipating unit 2 should have excellent heat dissipation and good structural strength, so it is preferably one of copper, aluminum, or an alloy thereof.

參閱圖3，以下將具體說明該第一實施例的聚光機制，當該燈具L通電並發光時，光線將從多個方向射出，其中，遠離該承載件11而沒接觸該等延伸件12的光線將持續向前投射，而向該等反射面121照射的光線，將會被該等反射面121反射進而也向前投射，進一步使該燈具L發射的光線往同一方向投射，達成匯聚多方向的光線於同一方向投射進而產生聚光的效果。於此同時，照射強光所伴隨而來的熱能，一部分會被從流經該通風孔111的氣流先行帶走，或是經由該承載件11往該導流通道13移動而被流經該導流通道13的氣流帶走，也會同時經由每一延伸件12之個別散熱面122，分別被導引到該等鰭片件21，再與空氣中的氣流進行熱交換，達成散熱的效果。 Referring to FIG. 3, the light focusing mechanism of the first embodiment will be described in detail below. When the lamp L is energized and emits light, light will be emitted from multiple directions, wherein it is away from the carrier 11 without contacting the extensions 12 The light of will continue to be projected forward, and the light irradiated to the reflective surfaces 121 will be reflected by the reflective surfaces 121 and then projected forward, so that the light emitted by the lamp L is projected in the same direction to achieve convergence The light in the same direction is projected in the same direction to produce a spotlight effect. At the same time, a part of the heat energy accompanying the strong light will be taken away from the airflow passing through the vent hole 111 first, or move to the diversion channel 13 through the carrier 11 to be passed through the guide The air flow of the flow channel 13 is also taken away through the individual heat dissipation surfaces 122 of each extension member 12 to be directed to the fin members 21 respectively, and then exchanges heat with the air flow in the air to achieve the effect of heat dissipation.

值得一提的是，當該氣流經由一側之該等鰭片件21流動並流經該導流通道13時，因為該等延伸件12彼此並未相連，而使鄰近該導流通道13之一側的該承載件11實質上會露出一部份而能夠與空氣接觸，並提供該氣流流動至另一該延伸件12的路徑，因此該氣流同樣能夠經由該導流通道13帶走熱能，於該導流通道13擴散後經由另一該延伸件12通過，並通過另一該延伸件12之該等鰭片件21而進一步帶走熱能，而能夠提升散熱的效果。 It is worth mentioning that when the airflow flows through the fins 21 on one side When moving and flowing through the diversion channel 13, because the extension members 12 are not connected to each other, the carrier 11 adjacent to one side of the diversion channel 13 will substantially expose a part of it and be able to contact with the air , And provide a path for the airflow to flow to the other extension 12, so the airflow can also take away heat energy through the guide channel 13, diffuse through the guide channel 13, pass through the other extension 12, and pass The fins 21 of the other extension 12 further take away the heat energy, which can improve the heat dissipation effect.

參閱圖4，該等鰭片件21只要彼此相間隔而提升與空氣接觸的表面積，即可達成所預期之功效，但需要特別說明的是，該等鰭片件21在特定的延伸方向時，能夠額外達成特殊的功效。以該第一實施例為例，該等鰭片件21是以平行於地面的方向往外延伸，藉由此一技術特徵，每二相鄰的該等鰭片件21間隔界定出的每一橫向貫通的導熱通道22。當環境多是以水平氣流H為主時，即可提供該等水平氣流H暢通的橫向熱交換途徑，進而提升散熱的效果。 Referring to FIG. 4, as long as the fins 21 are spaced apart from each other to increase the surface area in contact with air, the desired effect can be achieved, but it should be particularly noted that when the fins 21 are in a specific extension direction, Can achieve additional special effects. Taking the first embodiment as an example, the fins 21 extend outward in a direction parallel to the ground. With this technical feature, every two adjacent fins 21 are spaced apart in each lateral direction.通通的热热channel22. When the environment is dominated by the horizontal air flow H, the horizontal heat exchange path of the horizontal air flow H can be provided to improve the heat dissipation effect.

參閱圖5、6，則是本發明燈具散熱裝置之一第二實施例，與該第一實施例的主要差異在於：該等鰭片件21在使用時是如圖6所示地垂直於地面。藉由此一技術特徵，每二相鄰的該等鰭片件21間隔界定出的每一縱向貫通的導熱通道22。當該第二實施例是設置於容易產生煙囪效應的室內相對高處時，環境空氣大多是因為煙囪效應影響而垂直向上流動的垂直氣流V，設置於該第二實施例上的該燈具L之熱能，將會從該承載件11，經由該等延伸件12傳導至該等鰭片件21，再被垂直向上之該垂直氣流V帶走；於此同時，投射於該等反射面121的光線也會被匯聚而產生聚光的效果，也就是說，該第二實施例也同樣能夠達成聚光且散熱的效果。 5 and 6, it is a second embodiment of the heat dissipation device of the lamp of the present invention. The main difference from the first embodiment is that the fins 21 are perpendicular to the ground as shown in FIG. 6 when in use . With this technical feature, every two adjacent fin members 21 define each longitudinally-through heat conduction channel 22 at intervals. When the second embodiment is installed at a relatively high place in the room where the chimney effect is likely to occur, the ambient air is mostly a vertical air flow V that flows vertically upward due to the influence of the chimney effect. The lamp L provided in the second embodiment Thermal energy will be transferred from the carrier 11 through the extensions 12 The fins 21 are led to the vertical air flow V which is vertically upward; at the same time, the light rays projected on the reflective surfaces 121 are also concentrated to produce a light-concentrating effect, that is, the The second embodiment can also achieve the effects of condensing light and dissipating heat.

重新參閱圖1及圖2，最後，以下將會將該第一實施例及現有之一燈具散熱裝置，分別承載二具有相同之熱設計功耗要求的燈具，並在同一環境溫度下進行檢測，所得數據可整理為以下表一：

Referring back to FIGS. 1 and 2, finally, the first embodiment and one of the existing lamp heat dissipation devices will respectively carry two lamps with the same thermal design power consumption requirements and be tested at the same ambient temperature. The data obtained can be organized into the following table 1:

由上表可知，現有之該燈具散熱裝置與該第一實施例在經過90分鐘後的測試時間後，均能夠將最終溫度控制在78℃左右，但從物件重量來看，該第一實施例的淨重比現有之該燈具散熱裝置輕1100克，說明該第一實施例確實能藉由結構的改變來達成改善散熱效率的功效。且另一方面，倘若想將該第一實施例設置在散熱要求更高的燈具上，僅需在維持同樣結構的前提下進行體積的擴張，較大的該等延伸件12及該等鰭片件21能夠提升與空氣接觸的表面積，進一步提升散熱的效率，也就是說，當該第一實施例的淨重與現有之該燈具散熱裝置相同時，散熱效率將會更為優異。 It can be seen from the above table that the existing heat dissipation device of the lamp and the first embodiment can control the final temperature at about 78°C after a test time of 90 minutes, but from the perspective of the weight of the object, the first embodiment The net weight is 1100 grams lighter than the existing heat dissipation device of the lamp, indicating that the first embodiment can indeed achieve the effect of improving heat dissipation efficiency through structural changes. On the other hand, if the first embodiment is to be installed on a lamp with higher heat dissipation requirements, it is only necessary to expand the volume while maintaining the same structure. The larger extensions 12 and the fins The component 21 can increase the surface area in contact with the air and further improve the efficiency of heat dissipation. That is to say, when the net weight of the first embodiment is the same as the existing heat dissipation device of the lamp, the heat dissipation efficiency will be more excellent.

綜上所述，本發明燈具散熱裝置，藉由該等延伸件12 上的該等反射面121形成的聚光效果，配合該等鰭片件21產生散熱效果，以及針對環境流場方向設計的該等鰭片件21，更能夠配合施用環境進行更有效率地散熱，故確實能達成本發明之目的。 In summary, the heat dissipation device of the lamp of the present invention, through the extensions 12 The light-concentrating effect formed by the reflective surfaces 121 on the surface cooperates with the fins 21 to produce a heat dissipation effect, and the fins 21 designed for the direction of the environmental flow field can more effectively dissipate heat in accordance with the application environment Therefore, the purpose of cost invention can indeed be achieved.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention.
