Abstract
Description
本發明有關於一種發光二極體的光源，且特別是一種具有螢光粉之發光二極體的光源。 The invention relates to a light source for a light-emitting diode, and in particular to a light source having a light-emitting diode of phosphor powder.
發光二極體具有效率高、壽命長以及可靠性高等優點，可以搭配螢光粉以發出不同波長的光線，並作為照明光源。目前常見的螢光粉發光二極體光源主要包括基板、發光二極體以及螢光粉膠體。螢光粉膠體通常是螢光粉混矽膠所組成的膠狀混合物，而發光二極體通常設置在基板上，螢光粉膠體會包覆發光二極體以及基板。當發光二極體發射出一光線時，光線會通過螢光粉膠體，並且根據螢光粉膠體的種類，發出不同波長的出射光。 The light-emitting diode has the advantages of high efficiency, long life and high reliability, and can be matched with fluorescent powder to emit light of different wavelengths and used as an illumination source. At present, the common fluorescent powder light-emitting diode light source mainly comprises a substrate, a light-emitting diode and a phosphor powder colloid. The phosphor powder colloid is usually a gel-like mixture composed of a phosphor powder, and the light-emitting diode is usually disposed on the substrate, and the phosphor powder colloidally covers the light-emitting diode and the substrate. When the light emitting diode emits a light, the light passes through the phosphor powder colloid, and emits light of different wavelengths according to the type of the phosphor powder colloid.
然而當使用螢光粉膠體包覆發光二極體以及基板時，需要較大量的螢光粉膠體，會進而提升了製造成本。另外，螢光粉膠體的材質較軟，較無法提供發光二極體以及基板保護，使發光二極體以及基板容易受到碰撞而損壞。此外，螢光粉膠體的矽膠導熱係數較低，容易造成發光二極體光源散熱的問題。 However, when a phosphor paste is used to coat the light-emitting diode and the substrate, a larger amount of phosphor powder colloid is required, which further increases the manufacturing cost. In addition, the material of the phosphor powder colloid is relatively soft, and it is incapable of providing the light-emitting diode and the substrate protection, so that the light-emitting diode and the substrate are easily damaged by collision. In addition, the thermal conductivity of the phosphor powder colloidal gel is low, which easily causes the problem of heat dissipation of the light emitting diode light source.
本發明實施例提供一種發光二極體光源，其可以減少螢光粉膠體的用量。 Embodiments of the present invention provide a light emitting diode light source, which can reduce the amount of phosphor powder colloid.
本發明實施例提供一種發光二極體光源，所述發光二極體光源包括至少一基板、至少一發光二極體、至少一螢光粉膠體以及至少一透光中空管。發光二極體設置在基板上，並用以發出一光 線。螢光粉膠體配置在光線的傳遞路徑上。而透光中空管包圍基板以及發光二極體。 The embodiment of the invention provides a light emitting diode light source, wherein the light emitting diode light source comprises at least one substrate, at least one light emitting diode, at least one phosphor powder colloid, and at least one light transmissive hollow tube. The light emitting diode is disposed on the substrate and used to emit a light line. The phosphor powder colloid is placed on the light transmission path. The light-transmissive hollow tube surrounds the substrate and the light-emitting diode.
綜上所述，本發明提供一種發光二極體光源，其包括基板、發光二極體、螢光粉膠體以及透光玻璃管。螢光粉膠體覆蓋基板以及發光二極體。相較於先前技術中，螢光粉膠體包覆基板以及發光二極體，本實施例的螢光粉膠體用量較省。另外，透光中空管可以提供發光二極體光源足夠的支撐力，並且對基板、發光二極體以及螢光粉膠體進行保護。此外，由於透光中空管環繞發光二極體，發光二極體所發出的出射光可以360度的從透光中空管射出。 In summary, the present invention provides a light emitting diode light source comprising a substrate, a light emitting diode, a phosphor powder colloid, and a light transmissive glass tube. The phosphor powder colloid covers the substrate and the light emitting diode. Compared with the prior art, the phosphor powder coating substrate and the light emitting diode, the phosphor powder colloid of the embodiment is used in a relatively small amount. In addition, the light-transmissive hollow tube can provide sufficient supporting force for the light-emitting diode light source, and protect the substrate, the light-emitting diode, and the phosphor powder colloid. In addition, since the light-transmissive hollow tube surrounds the light-emitting diode, the light emitted from the light-emitting diode can be emitted from the light-transmitting hollow tube at 360 degrees.

圖1A是本發明第一實施例發光二極體光源100的結構立體示意圖，圖1B是本發明第一實施例發光二極體光源100的剖面放大示意圖。須說明的是，圖1B的剖面圖是沿著圖1A的A-A剖面線進行剖面而得的。請參閱圖1A以及圖1B，發光二極體光源100具有基板110、發光二極體120、螢光粉膠體130、導線W、透光中空管140以及接著體150。 1A is a perspective view showing the structure of a light-emitting diode light source 100 according to a first embodiment of the present invention, and FIG. 1B is an enlarged cross-sectional view showing the light-emitting diode light source 100 according to the first embodiment of the present invention. It should be noted that the cross-sectional view of Fig. 1B is taken along the line A-A of Fig. 1A. Referring to FIGS. 1A and 1B , the light-emitting diode light source 100 has a substrate 110 , a light-emitting diode 120 , a phosphor powder colloid 130 , a wire W , a light-transmissive hollow tube 140 , and a bonding body 150 .
請參閱圖1A的內容，基板110插設於透光中空管140中。接著體150設置於透光中空管140的兩端，以將基板110固設於透 光中空管140中，並密封透光中空管140。而透光中空管140會360度環繞包覆基板110。另外，請參閱圖1B的內容，發光二極體120設置於基板110上，並用以發出一光線。而螢光粉膠體130配置於光線的傳遞路徑上，用以接收光線。從圖1B可知，在本實施例中，螢光粉膠體130實際上是設置於基板110上，並用以覆蓋發光二極體120以及基板110。而該光線從發光二極體120發出，經由螢光粉膠體130會形成一出射光，而出射光會從透光中空管140射出。 Referring to the content of FIG. 1A , the substrate 110 is inserted into the transparent hollow tube 140 . The body 150 is disposed at both ends of the transparent hollow tube 140 to fix the substrate 110 The light hollow tube 140 is sealed in the light hollow tube 140. The light-transmissive hollow tube 140 wraps around the cladding substrate 110 360 degrees. In addition, referring to the content of FIG. 1B, the LEDs 120 are disposed on the substrate 110 and used to emit a light. The phosphor powder colloid 130 is disposed on the light transmission path for receiving light. As shown in FIG. 1B , in the present embodiment, the phosphor powder 130 is actually disposed on the substrate 110 and covers the LEDs 120 and the substrate 110 . The light is emitted from the light emitting diode 120, and an outgoing light is formed through the fluorescent powder colloid 130, and the emitted light is emitted from the transparent hollow tube 140.
接著體150會密封透光中空管140，以將基板110、發光二極體120、螢光粉膠體130以及導線W密封於透光中空管140中。如此一來，可以保護發光二極體120以及螢光粉膠體130，減少螢光粉膠體130受到外在水氣或者是粉塵的影響，進而可以延長發光二極體120以及螢光粉膠體130的使用壽命。此外，密封的透光中空管140中，還可以通入惰性氣體或者是抽真空的狀態。然而，本發明不限制透光中空管是否密封。在其他實施例中，接著體也可以僅用於將基板固定於透光中空管中。當透光中空管不為密封時，外界的空氣可以流入透光中空管中，可以將發光二極體所產生的熱氣給排出，提升發光二極體光源的散熱效果。 Then, the body 150 seals the light-transmissive hollow tube 140 to seal the substrate 110, the light-emitting diode 120, the phosphor powder colloid 130, and the wire W in the light-transmitting hollow tube 140. In this way, the LED body 120 and the phosphor powder colloid 130 can be protected, and the phosphor powder colloid 130 can be reduced from the external moisture or dust, thereby extending the LED body 120 and the phosphor powder colloid 130. Service life. Further, in the sealed transparent hollow tube 140, an inert gas or a vacuumed state may be introduced. However, the present invention does not limit whether the light-transmissive hollow tube is sealed. In other embodiments, the attachment body may also be used only to secure the substrate in the light transmissive hollow tube. When the transparent hollow tube is not sealed, the outside air can flow into the transparent hollow tube, and the hot air generated by the light emitting diode can be discharged to improve the heat dissipation effect of the light emitting diode light source.
請參閱圖1B，詳細而言，在本實施例中，基板110還包括一對連接端112、一本體114以及兩個連接體116(須說明的是，由於圖1B為局部放大示意圖，因此在圖1B中僅繪示其中一個連接端112以及一個連接體116)。連接端112位於本體114的兩側，且連接端112以及本體114會沿著同一方向延伸。連接端112與本體114之間是利用連接體116進行連接，兩個連接端112分別作為基板110的正極以及負極，並且可以連接外接電源。而發光二極體120會藉由導線W和連接端112電性連接，而外接電源可以提供發光二極體120發出光線所需電力。 Referring to FIG. 1B , in detail, in the embodiment, the substrate 110 further includes a pair of connecting ends 112 , a body 114 , and two connecting bodies 116 (note that, as shown in FIG. 1B , a partial enlarged view is Only one of the connecting ends 112 and one connecting body 116) are shown in FIG. 1B. The connecting end 112 is located on both sides of the body 114, and the connecting end 112 and the body 114 extend in the same direction. The connecting end 112 and the body 114 are connected by a connecting body 116. The two connecting ends 112 respectively serve as a positive pole and a negative pole of the substrate 110, and can be connected to an external power source. The light emitting diode 120 is electrically connected to the connecting end 112 by the wire W, and the external power source can provide the power required for the light emitting diode 120 to emit light.
須說明的是，在本實施例中，基板110的材質為金屬。然而， 在其他實施例中，基板的材質可以是透明導電材料，例如是氧化銦錫(Indium Tin Oxide,ITO)。當使用透明導電材料作為基板材料時，由於基板是透明的，且透光中空管140是360度環繞發光二極體，發光二極體所發出的光線可以360度的射出。也就是說發光二極體所發出的光線不僅可以從發光二極體的上方、左方或右方發出，還可以從發光二極體的下方發出，使得整個發光二極體光源100可以360度的發光。 It should be noted that, in this embodiment, the material of the substrate 110 is metal. however, In other embodiments, the material of the substrate may be a transparent conductive material such as Indium Tin Oxide (ITO). When a transparent conductive material is used as the substrate material, since the substrate is transparent, and the transparent hollow tube 140 is 360 degrees around the light emitting diode, the light emitted by the light emitting diode can be emitted 360 degrees. That is to say, the light emitted by the light-emitting diode can be emitted not only from above, to the left or to the right of the light-emitting diode, but also from below the light-emitting diode, so that the entire light-emitting diode light source 100 can be 360 degrees. Luminous.
另外，基板的材質還可以是陶瓷材料或者是玻璃，此時基板可以是一整個連板，不包括連接端以及連接體。基板的兩端可以另外電鍍上正負電極。本發明不限制基板的材質、基板的型態或者是基板的連接方式。此外，在其他實施例中，連接端及連接體的數量可以為一個，連接端位於本體的一側，且連接端藉由連接體與本體相連，然而本發明不以此為限。 In addition, the material of the substrate may also be ceramic material or glass. In this case, the substrate may be an entire connecting board, and does not include a connecting end and a connecting body. Both ends of the substrate may be additionally plated with positive and negative electrodes. The present invention does not limit the material of the substrate, the type of the substrate, or the manner in which the substrate is connected. In addition, in other embodiments, the number of the connecting end and the connecting body may be one, the connecting end is located at one side of the body, and the connecting end is connected to the body by the connecting body, but the invention is not limited thereto.
值得一提的是，在本實施例中，透光中空管140的材質可以是玻璃材質，玻璃材質可以提供發光二極體光源100足夠的支撐力，並且對基板110、發光二極體120、螢光粉膠體130以及導線W進行保護，以減少外界環境的水氣、粉塵或者是使用者在使用上可能造成損壞的機會。 It is to be noted that, in this embodiment, the material of the transparent hollow tube 140 may be a glass material, and the glass material can provide sufficient supporting force of the light emitting diode light source 100, and the substrate 110 and the light emitting diode 120 are The phosphor powder colloid 130 and the wire W are protected to reduce the moisture, dust or the possibility of damage to the user in use.
另外，由於透光中空管140環繞發光二極體120，發光二極體120所發出的出射光可以360度的從透光中空管140射出。此外，玻璃材質的透光中空管140導熱係數會較先前技術所使用的矽膠來得高，可以提高發光二極體光源100的散熱效果。然而，在其他實施例中，透光中空管140的材質也可以是壓克力或者是其他透光、有較高支撐力或者是有較佳導熱係數的材質，本發明不以此為限。 In addition, since the light-transmitting hollow tube 140 surrounds the light-emitting diode 120, the light emitted from the light-emitting diode 120 can be emitted from the light-transmitting hollow tube 140 at 360 degrees. In addition, the thermal conductivity of the glass-transparent hollow tube 140 is higher than that of the silicone used in the prior art, and the heat dissipation effect of the light-emitting diode source 100 can be improved. However, in other embodiments, the material of the transparent hollow tube 140 may also be acrylic or other light-transmitting, high-supporting force or a material having a better thermal conductivity, which is not limited by the present invention. .
除此之外，螢光粉膠體130可以是螢光粉以及矽膠混合而成的膠狀混合物。螢光粉可以是紅色螢光粉、黃色螢光粉或者是綠色螢光粉。另外，從圖1B的內容可知，螢光粉膠體130只有覆蓋 基板110、發光二極體120以及導線W。因此，相較於先前技術中，螢光粉膠體包覆基板以及發光二極體時，會消耗較大量的螢光粉膠體。在本實施例中，螢光粉膠體130的用量會較省。相對的，螢光粉的用量也會減少，降低了製造成本。 In addition, the phosphor powder colloid 130 may be a gelatinous mixture of phosphor powder and silicone rubber. The phosphor powder can be red phosphor powder, yellow phosphor powder or green phosphor powder. In addition, as can be seen from the content of FIG. 1B, the phosphor powder colloid 130 only covers The substrate 110, the light emitting diode 120, and the wire W. Therefore, compared with the prior art, when the phosphor powder colloidal coated substrate and the light emitting diode, a relatively large amount of phosphor powder colloid is consumed. In this embodiment, the amount of the phosphor powder colloid 130 may be less. In contrast, the amount of phosphor powder is also reduced, reducing manufacturing costs.
在實際操作中，發光二極體120發出的光線會經過螢光粉膠體130，並產生特定波長的出射光，而出射光會從透光中空管140射出以作為光源。舉例來說，在本實施例中，發光二極體120可以是藍光發光二極體，而螢光粉膠體130中的螢光粉可以是黃光螢光粉。如此一來，當發光二極體120發出的藍光光線經過螢光粉膠體130時，會和螢光粉膠體130的黃光螢光粉作用，並射出一白光出射光。然而，螢光粉膠體130的材質，會根據出射光的波長需求而進行調整，本發明不以此為限。 In actual operation, the light emitted by the LED 120 passes through the phosphor colloid 130 and generates an outgoing light of a specific wavelength, and the emitted light is emitted from the transparent hollow tube 140 as a light source. For example, in this embodiment, the light emitting diode 120 may be a blue light emitting diode, and the fluorescent powder in the fluorescent powder colloid 130 may be a yellow light fluorescent powder. As a result, when the blue light emitted by the LED 120 passes through the phosphor colloid 130, it acts on the yellow phosphor of the phosphor colloid 130 and emits a white light. However, the material of the phosphor powder 130 is adjusted according to the wavelength requirement of the emitted light, and the present invention is not limited thereto.
除此之外，在其他實施例中，透光中空管還可以具有至少一顏色，而發光二極體光源還可以搭配不同顏色的透光中空管來產生特定波長的出射光。舉例來說，透光中空管的顏色可以是紅色。當發光二極體為藍色發光二極體，螢光粉膠體的螢光粉為黃色螢光粉，從發光二極體發出的光線經過螢光粉膠體會形成一白光。白光再經過紅色的透光中空管，可以射出一黃色的出射光。 In addition, in other embodiments, the light-transmissive hollow tube may also have at least one color, and the light-emitting diode light source may also be combined with light-transmissive hollow tubes of different colors to generate emitted light of a specific wavelength. For example, the color of the light transmissive hollow tube can be red. When the light emitting diode is a blue light emitting diode, the fluorescent powder of the fluorescent powder colloid is a yellow fluorescent powder, and the light emitted from the light emitting diode passes through the fluorescent powder colloid to form a white light. The white light passes through the red transparent hollow tube to emit a yellow outgoing light.
須說明的是，在本實施例中，發光二極體光源100的發光二極體120以及螢光粉膠體130的種類皆為一種，例如發光二極體120皆為藍色發光二極體，螢光粉膠體130為黃色螢光粉。而透光中空管140的顏色只有一種，例如透光中空管140的顏色為紅色。然而，在其他實施例中，發光二極體光源也可以是兩種以上不同種類的發光二極體，且這兩種發光二極體會發出兩種以上不同波長的光線。而螢光粉膠體也可以是兩種以上不同種類的螢光粉膠體。當發光二極體的光線經過兩種不同種類的螢光粉膠體時，光線會轉換成兩種以上不同波長的出射光。另外，透光中空管的顏色可以有兩個，當光線經過螢光粉膠體，並從透光中空管射出時， 光線會轉換成不同波長的出射光。 It should be noted that, in this embodiment, the types of the LEDs 120 and the phosphor powders 130 of the LED source 100 are all one type, for example, the LEDs 120 are all blue LEDs. The phosphor powder colloid 130 is a yellow phosphor powder. The color of the transparent hollow tube 140 is only one type, for example, the color of the transparent hollow tube 140 is red. However, in other embodiments, the light emitting diode light source may also be two or more different types of light emitting diodes, and the two light emitting diodes emit light of two or more different wavelengths. The phosphor powder colloid may also be two or more different types of phosphor powder colloids. When the light of the light-emitting diode passes through two different kinds of phosphor powder colloids, the light is converted into two or more different wavelengths of the outgoing light. In addition, the light-transmissive hollow tube may have two colors, when the light passes through the phosphor powder colloid and is emitted from the transparent hollow tube. Light is converted into light of different wavelengths.
換句話說，發光二極體光源可以射出兩種不同波長的出射光。而發光二極體的種類數量、螢光粉膠體的種類數量以及透光中空管的顏色數量可以根據出射光的波長需求而進行調整。 In other words, the light-emitting diode source can emit two different wavelengths of outgoing light. The number of types of the light-emitting diodes, the number of types of the phosphor powder colloids, and the number of colors of the light-transmissive hollow tubes can be adjusted according to the wavelength requirements of the emitted light.
圖2為本發明第二實施例之發光二極體光源200的端面剖面示意圖，請參閱圖2。和前一實施例相同的是，本實施例發光二極體光源200也包括基板110、發光二極體120、透光中空管140以及接著體150，且各元件的相對位置關係也大致和前一實施例相同，在此不多做贅述。如圖2所示，不同於前一實施例，本實施例的發光二極體光源200還包括螢光粉膠體130a、130b。螢光粉膠體130a貼附於透光中空管140的外側表面，而螢光粉膠體130b貼附於透光中空管140的內側表面。 2 is a cross-sectional view showing an end face of a light-emitting diode light source 200 according to a second embodiment of the present invention, see FIG.

The previous embodiment is the same, and will not be described here. As shown in FIG. 2, unlike the previous embodiment, the LED light source 200 of the present embodiment further includes phosphor powder colloids 130a, 130b. The phosphor powder colloid 130a is attached to the outer side surface of the light transmissive hollow tube 140, and the phosphor powder colloid 130b is attached to the inner side surface of the light transmissive hollow tube 140.
當發光二極體120發出一光線時，光線會經過螢光粉膠體130b、透光中空管140以及螢光粉膠體130a，並且產生一特定波長的出射光。另外，由於螢光粉膠體130b是貼附於透光中空管140的內側表面，當光線經過螢光粉膠體130b時，光線會在透光中空管140的管壁進行折射，並且激發鄰近的螢光粉膠體130b，進而使得出射光可以360度的從透光中空管140射出。 When the light emitting diode 120 emits a light, the light passes through the phosphor powder colloid 130b, the light transmissive hollow tube 140, and the phosphor powder colloid 130a, and generates a specific wavelength of the emitted light. In addition, since the phosphor powder colloid 130b is attached to the inner side surface of the transparent hollow tube 140, when the light passes through the phosphor powder colloid 130b, the light is refracted on the tube wall of the transparent hollow tube 140, and the adjacent region is excited. The phosphor powder colloid 130b, in turn, allows the emitted light to be emitted from the light-transmissive hollow tube 140 at 360 degrees.
值得一提的是，螢光粉實際上容易在長時間的使用下，受到溫度的影響而改變發光的效率以及亮度。由於，在本實施例中，螢光粉膠體130a、130b是設置在透光中空管140的內外側表面。相較於前一實施例中，螢光粉膠體130覆蓋在基板110以及發光二極體120上，本實施例的螢光粉膠體130a、130b距離發光二極體120的較遠。因此，螢光粉膠體130a、130b中的螢光粉較不容易受到發光二極體120所產生的熱影響而變質，可以提升螢光粉膠體130a、130b的使用壽命。 It is worth mentioning that the fluorescent powder is actually easy to change the efficiency and brightness of the light by the influence of temperature under long-term use. Since, in the present embodiment, the phosphor powder bodies 130a, 130b are disposed on the inner and outer surfaces of the light transmissive hollow tube 140. Compared with the previous embodiment, the phosphor powder colloid 130 covers the substrate 110 and the light emitting diode 120, and the phosphor powders 130a and 130b of the present embodiment are far from the light emitting diode 120. Therefore, the phosphor powder in the phosphor powder bodies 130a and 130b is less susceptible to deterioration by the heat generated by the light-emitting diode 120, and the service life of the phosphor powder bodies 130a and 130b can be improved.
圖3為本發明第三實施例之發光二極體光源300的端面剖面示意圖，請參閱圖3。和前一實施例相同的是，本實施例發光二極 體光源300也包括基板110、發光二極體120、透光中空管140以及接著體150，且各元件的相對位置關係也大致和前一實施例相同，在此不多做贅述。然而，不同於第一實施例，本實施例的螢光粉膠體130’包括螢光粉層134以及膠體層132。 3 is a cross-sectional view showing an end face of a light-emitting diode light source 300 according to a third embodiment of the present invention, and FIG. The same as the previous embodiment, the light-emitting diode of this embodiment The body light source 300 also includes a substrate 110, a light-emitting diode 120, a light-transmissive hollow tube 140, and a bonding body 150, and the relative positional relationship of each element is also substantially the same as that of the previous embodiment, and details are not described herein. However, unlike the first embodiment, the phosphor paste 130' of the present embodiment includes the phosphor layer 134 and the colloid layer 132.
詳細而言，如圖3所示，膠體層132會覆蓋基板110、發光二極體120以及導線W，而螢光粉層134則會覆蓋在膠體層132的表面。當發光二極體120發出一光線時，光線會經過膠體層132以及螢光粉層134，以產生一特定波長的出射光。之後，出射光再經由透光中空管140射出。而光線經由螢光粉膠體130’以及透光中空管140射出的原理和前一實施例大致相同。然而，須說明的是，螢光粉實際上容易在長時間的使用下，受到溫度的影響而改變發光的效率以及亮度。由於在本實施例中，螢光粉層134以及發光二極體120之間還包括一膠體層132作為緩衝，本實施例的螢光粉層134距離發光二極體120的較遠。因此，螢光粉層134較不容易受到發光二極體120所產生的熱影響而變質，可以提升螢光粉層134的使用壽命。 In detail, as shown in FIG. 3, the colloid layer 132 covers the substrate 110, the light emitting diode 120, and the wire W, and the phosphor layer 134 covers the surface of the colloid layer 132. When the light emitting diode 120 emits a light, the light passes through the colloid layer 132 and the phosphor layer 134 to generate a specific wavelength of the outgoing light. Thereafter, the emitted light is emitted through the light transmitting hollow tube 140. The principle of light being emitted through the phosphor colloid 130' and the transparent hollow tube 140 is substantially the same as in the previous embodiment. However, it should be noted that the phosphor powder is actually easy to change the efficiency and brightness of the light by the influence of temperature under a long period of use. In this embodiment, the phosphor layer 134 and the LED body 120 further include a colloid layer 132 as a buffer. The phosphor layer 134 of the embodiment is far from the LED body 120. Therefore, the phosphor layer 134 is less susceptible to deterioration by the heat generated by the LED 120, and the service life of the phosphor layer 134 can be improved.
圖4是本發明第四實施例發光二極體光源400的結構立體示意圖，請參閱圖4。和前一實施例相同的是，本實施例發光二極體光源400也包括發光二極體120、螢光粉膠體130、透光中空管140以及接著體150。 4 is a perspective view showing the structure of a light-emitting diode light source 400 according to a fourth embodiment of the present invention, and FIG. The light-emitting diode light source 400 of the present embodiment also includes a light-emitting diode 120, a phosphor powder colloid 130, a light-transmissive hollow tube 140, and a bonding body 150, as in the previous embodiment.
然而，不同於第一實施例的是，發光二極體光源400的基板110’可定義出一彎折線L。如圖4所示，彎折線L將基板110’劃分為兩個部份。而發光二極體光源400包括兩個螢光粉膠體130、兩個透光中空管140以及兩組發光二極體120(須說明的是，一組發光二極體相當於，第一實施例之發光二極體光源100的發光二極體120的數量)，且分別位於基板110’的兩部份。 However, unlike the first embodiment, the substrate 110' of the light emitting diode light source 400 can define a bending line L. As shown in Fig. 4, the bending line L divides the substrate 110' into two parts. The light-emitting diode light source 400 includes two phosphor powders 130, two light-transmissive hollow tubes 140, and two sets of light-emitting diodes 120. (Note that a group of light-emitting diodes is equivalent to the first implementation. For example, the number of the LEDs 120 of the LED source 100 is located at two portions of the substrate 110'.
換句話說，本實施例的發光二極體光源400實際上可以視為兩組發光二極體光源100共用同一基板110’。另外，各元件的相 對位置關係和第一實施例相同，在此不多做贅述。須說明的是，本實施例的發光二極體光源400可以沿著彎折線L進行彎折，並設置於一燈罩中(圖未繪示)，以進行照明用。 In other words, the light-emitting diode light source 400 of the present embodiment can actually be regarded as two sets of light-emitting diode light sources 100 sharing the same substrate 110'. In addition, the phase of each component The positional relationship is the same as that of the first embodiment, and will not be described here. It should be noted that the LED light source 400 of the present embodiment can be bent along the bending line L and disposed in a lamp cover (not shown) for illumination.
綜上所述，本發明提供一種發光二極體光源，其包括基板、發光二極體、螢光粉膠體以及透光玻璃管。螢光粉膠體覆蓋基板以及發光二極體。相較於先前技術中，螢光粉膠體包覆基板以及發光二極體，本實施例的螢光粉膠體用量較省。另外，透光中空管可以提供發光二極體光源足夠的支撐力，並且對基板、發光二極體以及螢光粉膠體進行保護。此外，由於透光中空管環繞發光二極體，發光二極體所發出的出射光可以360度的從透光中空管射出。 In summary, the present invention provides a light emitting diode light source comprising a substrate, a light emitting diode, a phosphor powder colloid, and a light transmissive glass tube. The phosphor powder colloid covers the substrate and the light emitting diode. Compared with the prior art, the phosphor powder coating substrate and the light emitting diode, the phosphor powder colloid of the embodiment is used in a relatively small amount. In addition, the light-transmissive hollow tube can provide sufficient supporting force for the light-emitting diode light source, and protect the substrate, the light-emitting diode, and the phosphor powder colloid. In addition, since the light-transmissive hollow tube surrounds the light-emitting diode, the light emitted from the light-emitting diode can be emitted from the light-transmitting hollow tube at 360 degrees.
