Description
本發明係關於一種燈條燈具，尤係關於一種將燈條排列以形成圓狀光型輸出之燈條燈具。 The present invention relates to a light bar luminaire, and more particularly to a light bar luminaire in which light bars are arranged to form a circular light output.
發光二極體(Light Emitter Diode；LED)燈與傳統的白熾燈在相同的照度下比較，LED燈約可節省40%以上之電能效益，也因為如此，各國的節能措施當中包含了將LED導入各項照明領域，因而促使各式各樣的LED照明裝置之產生。 Light Emitter Diode (LED) lamps are compared with traditional incandescent lamps at the same illumination. LED lamps can save more than 40% of the energy efficiency. Because of this, the energy-saving measures in various countries include the introduction of LEDs. Various lighting fields have thus led to the creation of a wide variety of LED lighting devices.
LED燈條係一種將LED呈線性排列之發光裝置，由於製作容易、成本低，因此其應用逐漸地擴展開來。然而，一般常用之燈具中，提供具圓狀光型之圓形燈具是普遍地被使用。由於長方形LED燈條與圓形燈具先天之不相容性，因此，無法將較具經濟效益之LED燈條運用於圓形燈具中。 The LED light bar is a light-emitting device in which LEDs are linearly arranged, and its application is gradually expanded due to ease of manufacture and low cost. However, in a commonly used luminaire, a circular luminaire provided with a circular light type is generally used. Due to the inherent incompatibility of rectangular LED strips and circular luminaires, it is not possible to use more economical LED strips in circular luminaires.
鑒於上述之應用之不便，一般圓形燈具中採用LED的手段通常有二：一為使用單顆大功率之LED，然大功率之LED產熱多，因此需要良好之散熱，而此一需求將提高燈具設計複雜度，增加成本；二為使用圓形電路板，將LED於圓形電路板做陣列排列，使其可投射出圓形光型，雖此一手段可達成投射出圓形光型之目的，然而，圓形電路板具成本高等之不利因素。 In view of the inconvenience of the above applications, there are generally two ways to use LEDs in a circular luminaire: one is to use a single high-power LED, but the high-power LED generates more heat, so it needs good heat dissipation, and this demand will be Improve the complexity of the luminaire design and increase the cost; secondly, use a circular circuit board to arrange the LEDs in a circular circuit board so that they can project a circular light pattern, although this method can achieve a circular light pattern The purpose, however, is that the circular circuit board has a disadvantage of high cost.
綜上所述，LED燈條係一種製作容易、成本低之照明裝置，然而目前仍無法將此一具經濟效益之LED燈條運用於普 遍使用之圓形燈具上。而此一技術之突破，實待研究開發。 In summary, the LED light bar is a lighting device that is easy to manufacture and low in cost. However, it is still impossible to apply this economical LED light bar to the general lighting. Used on round lamps. The breakthrough of this technology is subject to research and development.

And with this arrangement method, an optical output close to a circle can be obtained. Moreover, in this manner, since the light bars 102 have a relatively spaced space, the efficiency of convection of the hot and cold air can be improved. What is more, the present invention discloses that the light bar 102 is arranged to produce a circular light output, and the present invention has better fault replacement than conventional techniques using a circular circuit board. That is, if there is an LED failure, the entire circuit board needs to be replaced by a circular circuit board, and the technology disclosed in the present invention only needs to replace the light bar 102 where the faulty LED is located.
第一端部304固定於環形部106上之方式有許多種，本實施例係以螺絲204將電路板202上相對應之開孔(未繪示)鎖入位於環形部106上相對應之螺孔(未繪示)。 There are a plurality of ways in which the first end portion 304 is fixed to the annular portion 106.

And abutting one of the side edges 308 of the light bar 102 adjacent thereto. Therefore, in the technique disclosed in the present invention, at least three or more light bars 102 may be annularly arranged in the light bar lamp 100 to produce a circular light pattern. The positions at which the light bars 102 are abutted may be the same so that the surrounding polygonal regions 310 have the same inner angle at the center position. However, this condition is preferred but not necessary, for example, surrounded by four light bars 102. The polygonal area 310 may be a parallelogram which is not equivalent to the inner angle except for the square shape.
參照圖1與圖8，本發明所揭示之燈條燈具100’可嵌置於一直立式之燈罩802之靠近開口806之一容置空間808內，使其成為一直立式嵌燈800。燈條102之電源可由置放於嵌燈800內之電源模組108’供應。由於燈條102間之間隔空隙，使燈條102之產熱可輕易地從嵌燈800頂部之對流孔804，以自然熱對流之方式散熱(沿箭頭方向)，並避免燈條102過熱。 Referring to Figures 1 and 8, the light bar luminaire 100' of the present invention can be embedded in an accommodating space 808 adjacent to the opening 806 of the vertical hood 802 to form the vertical downlight 800. The power source of the light bar 102 can be supplied by a power module 108' placed in the recessed light 800. Due to the gap between the light bars 102, the heat generated by the light bar 102 can be easily dissipated from the convection hole 804 at the top of the recessed lamp 800 in a natural heat convection (in the direction of the arrow) and the light bar 102 is prevented from being overheated.
參照圖9，直立式嵌燈800’之頂部可具有一螺絲燈帽902，利用該螺絲燈帽902可將該直立式嵌燈800’固定於其相 對應之母螺絲槽(未繪示)中，藉此將本發明所揭示之技術可相容於傳統之燈具。藉由螺絲燈帽902與電源線904，使外部電源可提供於燈條102。 Referring to Figure 9, the top of the upright recessed light 800' can have a screw cap 902 with which the upright recessed light 800' can be secured to its phase. Corresponding to the female screw groove (not shown), the technology disclosed by the present invention can be compatible with conventional lamps. An external power source can be provided to the light bar 102 by the screw cap 902 and the power cord 904.
參照圖1與圖10，本發明所揭示之燈條燈具100’亦可嵌置於一水平式之燈罩1002內，使其成為一水平式嵌燈1000。受限於水平式嵌燈1000之容積，燈條102之電源模組1006須置放於嵌燈1000外。由於燈條102間之間隔空隙，使燈條102之產熱可輕易地從嵌燈1000上方之對流孔1004，以自然熱對流之方式散熱(沿箭頭方向)，並避免燈條102過熱。 Referring to Figures 1 and 10, the light bar fixture 100' of the present invention can also be embedded in a horizontal shade 1002 to form a horizontal recessed light 1000. Limited to the volume of the horizontal downlight 1000, the power module 1006 of the light bar 102 must be placed outside the recessed light 1000. Due to the gap between the light bars 102, the heat generated by the light bar 102 can be easily dissipated from the convection hole 1004 above the recessed lamp 1000 in a natural heat convection (in the direction of the arrow), and the light bar 102 is prevented from being overheated.
綜合所述，本發明揭示之技術係利用低成本之燈條，以環形排列之方式固定於燈具中，並藉此產生接近圓形的光型輸出，其中燈條與其對應之散熱元件可組合成一模組，以利於更換之便利性。此揭露之技術具模組擴充性與替換、結構簡單、可利用低成本之散熱元件及重量輕等優點。 In summary, the technology disclosed in the present invention utilizes a low-cost light bar to be fixed in a circular arrangement in a luminaire, and thereby produces a nearly circular optical output, wherein the light bar and its corresponding heat dissipating component can be combined into one Modules to facilitate the convenience of replacement. The disclosed technology has the advantages of modular expansion and replacement, simple structure, low cost heat dissipation components and light weight.
