Description
本發明為一種散熱型燈座,尤其指一種能提供對稱光型的間接照明,同時也兼具良好散熱效果的設計。 The invention is a heat-dissipating lamp holder, in particular to a design capable of providing indirect illumination of a symmetrical light type, and also having a good heat dissipation effect.
近幾年來,多數燈具皆採用發光二極體作為主要光源,透過矩形陣列的分佈方式,達到所需之亮度,但發光二極體屬於點光源,使用者直視容易造成失能性眩光,功率過大,恐怕影響視力。目前業界普遍的作法是於出光口的玻璃上磨沙或採用半透明壓克力板(例如PC板、塑料板…等),減少使用者直視發光二極體對眼睛造成的傷害與保障工作的安全,但如此會造成光通量的耗損。 In recent years, most of the lamps use the light-emitting diode as the main light source, and the distribution of the rectangular array is used to achieve the required brightness. However, the light-emitting diode is a point light source, and the user may directly cause disability glare, and the power is too large. I am afraid it will affect my eyesight. At present, the common practice in the industry is to sand the glass on the light exit port or use a translucent acrylic plate (such as PC board, plastic board, etc.) to reduce the damage and protection of the eyes caused by the user directly looking at the light-emitting diode. Safe, but this will cause loss of luminous flux.
因此有些廠商採用反射式的間接照明,原理是將光線投射於與出光口方向不同的反射面,透過反射面的反射,導引光線最終經該出光口投射出去,但是此種間接照明,有兩項問題須克服:一、採用反射方式若不加以設計,光通量損耗過大;二、照明的光型容易產生偏移,如圖8所示,圖中粗線為燈具垂直面的光形分佈圖,細線為燈具平行面的光形分佈圖,當此類燈具安裝高度及角度有所偏差,就會影響照明區域的亮度,造成此類燈具在安裝時,安裝人員須具備相當的技術或須進行額外的光型校正動作,耗時及費工,降低使用者的使用意願。 Therefore, some manufacturers use reflective indirect illumination. The principle is to project light onto a reflecting surface that is different from the direction of the light exiting port. Through the reflection of the reflecting surface, the guiding light is finally projected through the light exiting port. However, there are two such indirect illuminations. The problem must be overcome: First, if the reflection method is not designed, the luminous flux loss is too large; Second, the illumination type is easy to produce offset, as shown in Figure 8, the thick line in the figure is the light distribution map of the vertical surface of the lamp. The thin line is the light distribution map of the parallel faces of the lamps. When the installation height and angle of such lamps are deviated, the brightness of the lighting area will be affected. When installing such lamps, the installers must have considerable technology or additional The light-correcting action is time-consuming and labor-intensive, reducing the user's willingness to use.
