Abstract
Description
本發明是有關於一種燈具。The invention relates to a luminaire.
隨著半導體技術的進步，發光二極體(light-emitting diode,LED)所能達到的功率越來越大，且所發出的光之強度越來越高。此外，發光二極體更具有省電、使用壽命長、環保、啟動快速、體積小...等優點。因此，發光二極體也被廣泛地應用於照明設備、交通號誌、顯示器、光學滑鼠...等產品，且更有逐漸取代傳統螢光燈具的趨勢。With the advancement of semiconductor technology, the power that light-emitting diodes (LEDs) can achieve is getting larger and larger, and the intensity of light emitted is getting higher and higher. In addition, the light-emitting diode has the advantages of power saving, long service life, environmental protection, fast startup, small size, and the like. Therefore, the light-emitting diodes are also widely used in lighting equipment, traffic signs, displays, optical mice, etc., and there is a tendency to gradually replace the traditional fluorescent lamps.
發光二極體具有指向性(directivity)，亦即其所發出的光會集中於某一個方向上。當發光二極體用於一般照明時，通常須使發光二極體作適當的排列，以使光線能夠射向不同的方向，進而盡量使環境中的各處都能被光線所照射。The light-emitting diode has directivity, that is, the light emitted by it is concentrated in one direction. When the light-emitting diode is used for general illumination, it is usually necessary to arrange the light-emitting diodes so that the light can be directed in different directions, so as to make the light everywhere as much as possible in the environment.
在一種習知發光二極體燈具中，是將發光二極體排列成相對一對稱軸旋轉對稱，而使發光二極體所發出的光沿著垂直於此對稱軸的徑向輻射。然而，由於光線都集中於徑向，因此這種發光二極體燈具有在軸向(沿著對稱軸的方向)照度不足的問題。舉例而言，若將此種發光二極體燈具安裝於天花板上時，會使得發光二極體燈具的正下方照度不足，如此會不利於使用者閱讀或從事其他需要充分照明的活動。In a conventional light-emitting diode lamp, the light-emitting diodes are arranged to be rotationally symmetric with respect to a symmetry axis, and the light emitted by the light-emitting diodes is radiated in a radial direction perpendicular to the axis of symmetry. However, since the light is concentrated in the radial direction, such a light-emitting diode lamp has a problem that the illuminance is insufficient in the axial direction (the direction along the axis of symmetry). For example, when such a light-emitting diode lamp is mounted on a ceiling, the illumination below the light-emitting diode lamp is insufficient, which may be disadvantageous for the user to read or engage in other activities requiring sufficient illumination.
另一種習知發光二極體燈具額外增加了其他發光方向的發光二極體來解決上述問題，而這些其他發光方向的發光二極體所發出的光會沿著軸向發出。然而，增加了其他發光方向的發光二極體須同時採用其他配置方向的電路板，這會導致發光二極體燈具的內部結構過於複雜、不利於散熱，且會使發光二極體燈具的成本提高。Another conventional light-emitting diode lamp additionally adds light-emitting diodes of other light-emitting directions to solve the above problems, and the light emitted by the light-emitting diodes of these other light-emitting directions is emitted along the axial direction. However, the light-emitting diodes with other light-emitting directions must use other circuit boards in the same direction, which may cause the internal structure of the light-emitting diode lamps to be too complicated, which is disadvantageous for heat dissipation, and the cost of the light-emitting diode lamps is increased. .
本發明提供一種燈具，其能同時在多個方向上提供足夠的照明。The present invention provides a luminaire that provides sufficient illumination in multiple directions simultaneously.

The reflector has a bottom and a light exit section. A part of each of the light-emitting modules is disposed in the reflector, and each of the light-emitting modules includes a carrier and a plurality of light-emitting elements. These light emitting elements are arranged on a carrier board. A portion of the illuminating elements are located within the reflector and are located between the bottom and the exit section, and another portion of the illuminating elements are exposed outside the reflector.
在本發明之一實施例中，各個發光元件具有一光軸，且這些發光元件的這些光軸實質上平行於出光截面。In one embodiment of the invention, each of the light emitting elements has an optical axis, and the optical axes of the light emitting elements are substantially parallel to the light exiting cross section.
在本發明之一實施例中，各個發光元件例如為一發光二極體。In an embodiment of the invention, each of the light-emitting elements is, for example, a light-emitting diode.
在本發明之一實施例中，各個發光模組之這些發光元件沿著實質上垂直出光截面的方向排列。In one embodiment of the invention, the light emitting elements of each of the light emitting modules are arranged in a direction that is substantially perpendicular to the light exiting cross section.
在本發明之一實施例中，這些發光模組環繞一通過出光截面的中心軸線配置。In one embodiment of the invention, the lighting modules are disposed about a central axis passing through the exit section.
在本發明之一實施例中，燈具更包括一散熱座，散熱座的一部分配置於反射燈罩內，且這些發光模組配置於散熱座上。散熱座可具有多個凹槽，且這些發光模組分別配置於這些凹槽中。這些凹槽可沿著實質上垂直於出光截面的方向延伸。In an embodiment of the invention, the luminaire further includes a heat sink, and a part of the heat sink is disposed in the reflector, and the light modules are disposed on the heat sink. The heat sink can have a plurality of grooves, and the light emitting modules are respectively disposed in the grooves. These grooves may extend in a direction substantially perpendicular to the light exiting cross section.
在本發明之一實施例中，燈具更包括一驅動電路，其配置於反射燈罩的底部，並位於反射燈罩中，而驅動電路電性連接至這些發光模組。燈具可更包括一電性接頭，其配置於底部上，並位於反射燈罩外，其中電性接頭電性連接至驅動電路。In an embodiment of the invention, the luminaire further includes a driving circuit disposed at the bottom of the reflector and located in the reflector, and the driving circuit is electrically connected to the illuminating modules. The luminaire can further include an electrical connector disposed on the bottom and outside the reflector, wherein the electrical connector is electrically connected to the driving circuit.
在本發明之一實施例中，燈具更包括一透光燈罩，其係配置於反射燈罩上，其中暴露於反射燈罩外的這些發光元件的另一部分收容於透光燈罩中。透光燈罩可具有多個透氣開口，且這些透氣開口貫穿透光燈罩。In an embodiment of the invention, the light fixture further includes a light-transmitting lamp cover disposed on the reflector lamp cover, wherein another portion of the light-emitting elements exposed outside the reflector lamp cover is received in the light-transmitting lamp cover. The light transmissive lamp cover can have a plurality of gas permeable openings, and the gas permeable openings extend through the light transmissive lamp cover.
在本發明之一實施例中，反射燈罩具有一反射面，其係位於反射燈罩的內壁。藉由反射面將位於反射燈罩內的這些發光元件所發出的光反射至出光截面，且位於反射燈罩內的這些發光元件的部分所發出的光會通過出光截面而往遠離底部的方向傳遞。反射面例如為凹面。反射燈罩可具有多個透氣開口，且這些透氣開口貫穿反射燈罩。In an embodiment of the invention, the reflector cover has a reflective surface that is located on the inner wall of the reflector. The light emitted by the light-emitting elements located in the reflector is reflected by the reflecting surface to the light-emitting section, and the light emitted by the portions of the light-emitting elements located in the reflector is transmitted through the light-emitting section in a direction away from the bottom. The reflecting surface is, for example, a concave surface. The reflector can have a plurality of venting openings and the venting openings extend through the reflector.
本發明之另一實施例提出一種燈具，其包括上述反射燈罩及上述發光模組及一透光燈罩。各個發光模組環繞一通過出光截面的中心軸線配置。透光燈罩配置於反射燈罩上，其中暴露於上述反射燈罩外的發光元件的上述另一部分收容於上述透光燈罩中。Another embodiment of the present invention provides a light fixture including the reflector lamp cover, the light emitting module, and a light-transmitting lamp cover. Each of the light emitting modules is disposed around a central axis passing through the light exiting section. The light-transmitting lamp cover is disposed on the reflector lamp cover, and the other portion of the light-emitting element exposed to the outside of the reflector lamp cover is received in the light-transmitting lamp cover.
基於上述，在本發明之實施例之燈具中，各個發光模組的這些發光元件的一部分位於反射燈罩內，而另一部分暴露於反射燈罩外。由於位於反射燈罩內的發光元件所發出的光會被反射燈罩反射，而射向遠離反射燈罩的底部之方向，且暴露於反射燈罩外的發光元件所發出的光則射向另一方向，因此本發明之實施例之燈具能同時在多個方向上提供足夠的照明。Based on the above, in the luminaire of the embodiment of the present invention, a part of the light-emitting elements of each of the light-emitting modules are located inside the reflector, and another portion is exposed outside the reflector. Since the light emitted by the light-emitting elements located in the reflector is reflected by the reflector, and is directed away from the bottom of the reflector, and the light emitted by the light-emitting elements exposed outside the reflector is directed to the other direction, The luminaire of an embodiment of the invention can provide sufficient illumination in multiple directions simultaneously.

The driving circuit 140 is electrically connected to the light emitting modules 120 to drive the light emitting elements 124 to emit light. In the embodiment, the driving circuit 140 is, for example, a driving circuit board. The luminaire 100 can further include an electrical connector 150 disposed on the bottom portion 112 and located outside the reflector cover 110. The electrical connector 150 is electrically connected to the driving circuit 140. In this embodiment, the electrical connector 150 can be electrically connected to an external power source, for example, the electrical connector 150 is screwed into a socket (not shown).
在本實施例中，燈具100更包括一透光燈罩160，其係配置於反射燈罩110上，其中暴露於反射燈罩110外的這些發光元件124的另一部分(例如發光元件124b)收容於透光燈罩160中。發光元件124(如發光元件124a與124b)所發出的光127(如發光元件124a所發出的光127a及發光元件124b所發出的光127b)會通過透光燈罩160而傳遞至外界。In this embodiment, the luminaire 100 further includes a light-transmitting lamp cover 160 disposed on the reflector cover 110, wherein another portion of the light-emitting elements 124 (for example, the light-emitting elements 124b) exposed to the outside of the reflector cover 110 is housed in the light-transmitting member. In the lampshade 160. The light 127 emitted by the light-emitting elements 124 (such as the light-emitting elements 124a and 124b) (such as the light 127a emitted by the light-emitting element 124a and the light 127b emitted by the light-emitting element 124b) is transmitted to the outside through the light-transmitting cover 160.
在本實施例中，反射燈罩110具有一反射面116，其係位於反射燈罩110的內壁。藉由反射面116將位於反射燈罩110內的這些發光元件124(如發光元件124a)所發出的光127a反射至出光截面114，且光127a會通過出光截面114而往遠離底部112的方向傳遞。在本實施例中，光127a可接著通過透光燈罩160的頂部162而傳遞至外界。在本實施例中，反射面116例如為凹面，以調整光127a射出至外界的方向。然而，在其他實施例中，反射面116亦可以是平面、凸面或其他形狀的表面。在本實施例中，反射燈罩110例如是以塑膠材質製成，而其內壁藉由電鍍或噴塗反射膜，以形成反射面116。然而，在其他實施例中，反射燈罩110亦可以是用金屬或其他材質所製成。In the present embodiment, the reflector cover 110 has a reflective surface 116 that is located on the inner wall of the reflector 110. The light 127a emitted by the light-emitting elements 124 (such as the light-emitting elements 124a) located in the reflector 110 is reflected by the reflecting surface 116 to the light-emitting section 114, and the light 127a is transmitted through the light-emitting section 114 in a direction away from the bottom 112. In the present embodiment, light 127a can then be transmitted to the outside through the top 162 of the light transmissive cover 160. In the present embodiment, the reflecting surface 116 is, for example, a concave surface to adjust the direction in which the light 127a is emitted to the outside. However, in other embodiments, the reflective surface 116 can also be a planar, convex or other shaped surface. In the present embodiment, the reflector cover 110 is made of, for example, a plastic material, and the inner wall thereof is plated or sprayed with a reflective film to form a reflective surface 116. However, in other embodiments, the reflector cover 110 can also be made of metal or other materials.
在本實施例之燈具100中，發光元件124b所發出的光127b可直接通過透光燈罩160而射出至外界，亦即沿著垂直於中心軸線C的徑向輻射至外界。另一方面，發光元件124a所發出的光127a則會被反射燈罩110反射至出光截面114，並沿著大約平行於中心軸線C的方向(即軸向)傳遞至透光燈罩160，且接著通過透光燈罩160而傳遞至外界。如此一來，燈具100在徑向與軸向所提供的光強度便能夠較為接近，因此當燈具100用於一般照明用途時，便能夠較為均勻地照亮環境中的各個區域。In the luminaire 100 of the present embodiment, the light 127b emitted by the illuminating element 124b can be directly emitted to the outside through the translucent cover 160, that is, radiated to the outside in a radial direction perpendicular to the central axis C. On the other hand, the light 127a emitted by the light-emitting element 124a is reflected by the reflector 110 to the light-emitting section 114, and transmitted to the light-transmitting cover 160 in a direction approximately parallel to the central axis C (ie, the axial direction), and then passed. The light cover 160 is transmitted to the outside. In this way, the light intensity provided by the luminaire 100 in the radial direction and the axial direction can be relatively close, so that when the luminaire 100 is used for general illumination purposes, the various areas in the environment can be more uniformly illuminated.
在本實施例中，反射燈罩110可具有多個透氣開口118，且這些透氣開口118貫穿反射燈罩110。透氣開口118可使燈具100內部與外部的空氣流通，以增進發光元件124的散熱。此外，在本實施例中，透光燈罩160可具有多個透氣開口164，且這些透氣開口164貫穿透光燈罩160。透氣開口164亦可使燈具100內部與外部的空氣流通，以增進發光元件124的散熱。在本實施例中，透氣開口164例如是位於透光燈罩160的頂部162，亦即透光燈罩160之遠離反射燈罩110之一端。透氣開口118與透氣開口164例如皆為長條狀開口。然而，在其他實施例中，透氣開口118與透氣開口164亦可以是呈其他形狀的開口。In the present embodiment, the reflector cover 110 can have a plurality of venting openings 118 and the venting openings 118 extend through the reflector 110. The venting opening 118 allows air to circulate inside and outside the luminaire 100 to enhance heat dissipation from the illuminating element 124. Moreover, in the present embodiment, the light transmissive lamp cover 160 may have a plurality of gas permeable openings 164, and the gas permeable openings 164 extend through the light transmissive lamp cover 160. The venting opening 164 also circulates air inside and outside the luminaire 100 to enhance heat dissipation from the illuminating element 124. In the present embodiment, the venting opening 164 is, for example, located at the top 162 of the translucent cover 160, that is, one end of the translucent cover 160 away from the reflector 110. Both the venting opening 118 and the venting opening 164 are, for example, elongated openings. However, in other embodiments, the venting opening 118 and the venting opening 164 may also be openings in other shapes.
綜上所述，在本發明之實施例之燈具中，各個發光模組的這些發光元件的一部分位於反射燈罩內，而另一部分暴露於反射燈罩外。由於位於反射燈罩內的發光元件所發出的光會被反射燈罩反射，而射向遠離反射燈罩的底部之方向(如軸向)，且暴露於反射燈罩外的發光元件所發出的光則射向另一方向(如徑向)，因此本發明之實施例之燈具能同時在多個方向上提供足夠的照明，例如可使軸向發出的光之強度與徑向發出的光之強度較為接近。In summary, in the luminaire of the embodiment of the invention, a part of the illuminating elements of each illuminating module is located in the reflector, and the other part is exposed outside the reflector. Since the light emitted by the light-emitting elements located in the reflector is reflected by the reflector, and is directed away from the bottom of the reflector (such as the axial direction), the light emitted by the light-emitting elements exposed outside the reflector is directed to the other In one direction (e.g., radial), the luminaire of an embodiment of the present invention can provide sufficient illumination in multiple directions at the same time, for example, the intensity of the light emitted from the axial direction is relatively close to the intensity of the light emitted radially.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，故本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
