照明消耗了大量的能源,据统计,全球每年发电量的20%被用于照明。 Lighting consumes a lot of energy, according to statistics, 20% of global annual generating capacity is used for lighting. 白炽灯和荧光管是目前最为常用的两种传统白光光源,但是它们对能量的利用效率都不高-白炽灯将90%的能量转化为了热能,造成了大量的能源浪费,而荧光管也只利用了70%的能量用于发光。 Incandescent and fluorescent tube is the most commonly used two traditional white light sources, but they use energy efficiency is not high - 90 percent of the incandescent energy conversion to heat, causing a great deal of energy waste, while fluorescent tubes only 70% of the energy utilized for light emission. 基于此,白炽灯的发光效率一般为13 lm/W〜20 lm/W,而荧光管为901m/W。 Based on this, the luminous efficiency of an incandescent lamp is generally 13 lm / W~20 lm / W, and the fluorescent tube is 901m / W. 为了节约能源,提高能量利用效率,开发新型白光光源是很有意义和前景的。 To save energy, improve energy efficiency, develop new white light source is of great significance and prospects.

有机电致发光二极管(organic light-emitting diodes, 0LED)技术在过去近20年间吸引了广泛的研究注意力并取得了长足的进步。 The organic light-emitting diodes (organic light-emitting diodes, 0LED) technology during the past 20 years, extensive research has attracted attention and has made considerable progress. 随着单色OLED的性能逐渐成熟,白光OLED (white organic light-emitting diodes, WOLED)作为一种新型的固态光源,在照明和平板显示背光源等方面展现了良好的应用前景,已经吸引了人们越来越多的注意。 With monochrome OLED performance mature, white OLED (white organic light-emitting diodes, WOLED) as a new type solid state light source, in terms of lighting and a flat panel display backlight, exhibits good application prospect has attracted people more and more attention. 1994年,日本的Kido等人制备了第一块WOLED ,在器件中同时包含红光、绿光和蓝光发射,混合组成白光。 In 1994, a Japanese WOLED prepared Kido et al., Contains red, green and blue emission device, the composition of the mixed white light. 由于器件结构和材料选择的问题,器件的能量效率低于1 lm/W,驱动电压很高而且稳定性较差。 Since the device structure and materials of choice, the energy efficiency of the device is less than 1 lm / W, the driving voltage is high and is less stable. 但在随后的研究中,WOLED的效率和性能得到了飞速的提高。 However, in subsequent studies, efficiency and performance WOLED has been rapid improvement. 目前,OLED在实验室研究中已经取得了301m/W~601m/W的总能量效率,已经大大超过了白炽灯光源。 Currently, OLED in laboratory studies has been made overall energy efficiency of 301m / W ~ 601m / W have been much higher than the incandescent light sources.

目前已经有许多寿命超过2万小时的单色OLED的报道,但TOLED的典型寿命仍然小于5000小时,为了达到并超过荧光管的效率和寿命,W0LED仍然面临许多难题和挑战。 There are already a lot of life more than 20,000 hours of monochrome OLED reports, but the typical lifetime TOLED still less than 5000 hours, in order to meet and exceed the efficiency and life of the fluorescent tube, W0LED still faces many difficulties and challenges.

本发明实施例相似于如图1所示的现有技术的有机电致发光照明光源器件,区别在于在本发明的有机电致发光光源即发光照明区域230的周边区域分布有至少一个阳极或阴极散热部件,而且这些散热部件分别与该照明光源器件中阳极层250和阴极层240相连接,直接起到导热和散热作用。 Embodiment of the invention similar to the prior art shown in FIG. 1, the organic electroluminescent illuminating light source device, except that in the present invention has an organic electroluminescent light source that is emitting the illumination distribution region 230 has a peripheral region at least one anode or cathode heat radiating member, the heat radiating member and the illumination light source device, respectively in the anode layer 250 and cathode layer 240 is connected directly play a role in thermal conductivity and heat dissipation.

有机电致发光照明光源器件230是较大尺寸的用于照明的光源,例如对角线大于4英寸,以大电流驱动的高亮度光源。 The organic electroluminescent illumination source 230 is a light source device for illumination of larger dimensions, for example, greater than 4 inches diagonal, high brightness light source with a large current drive. 由于大尺寸照明光源需要大量的电流注入器件,而这种电力消耗必然使得有机电致发光照明光源230产生大量的热,这就不断提高有机电致发光器件230的操作温度。 Due to the large size of the illumination light source requires a large amount of current injection devices, the power consumption and this inevitably makes the organic electroluminescent illumination source 230 generates a lot of heat, which has to continuously improve the operating temperature of the organic electroluminescent device 230. 当操作温度的升高,对于玻璃转化温度点在IOO左右的OLED有机材料而言,可明显的发现OLED亮度的降低。 When the operating temperature increases, the glass transition temperature point in terms of the organic material around the IOO OLED, OLED can significantly reduce the brightness of the discovery. 一方面,器件温度的提高易使得有机电致发光器件230老化的速度加快,这样,就必然导致有机电致发光器件230发光效率和稳定性的降低。 In one aspect, the temperature increase of the device makes it easy to speed the organic electroluminescent device 230 accelerated aging, so that it will inevitably lead to reduced efficiency and stability of the light-emitting organic electroluminescent device 230. 另一方面,在大面积面光源中间区域的热量很难散发出来,最后导致中间区域有机材料逐渐变性,致使器件发光慢慢变暗,更有甚者,直接导致中间区域有机材料的熔化,进而烧毁器件。 On the other hand, heat in the large area plane light source comes out of the intermediate region is difficult, leading to an intermediate region of the organic material is progressively modified, resulting in a light emitting device slowly darken more, a direct result of the melting of the intermediate region of the organic material, and thus burning devices. 根据本发明的一优选实施方式,利用基板210周边区域的阳极或阴极散热部件,与有机电致发光器件的电极层直接相连接,可将有机电致发光器件130所产生的热,有效导出有机电致发光器件130,以避免有机电致发光器件130因操作温度过高而毁坏。 According to a preferred embodiment of the present invention, the use of the anode or cathode peripheral region of the heat radiating member substrate 210, the electrode layer organic electroluminescent device is directly connected, may be hot organic electroluminescent device 130 generates effective derived there the organic electroluminescent device 130, in order to avoid the organic electroluminescent device 130 due to high temperature operation destroyed.

值得注意的是,因为这些阳极或阴极散热内件270和260还只是在封接盖220 之中,此时导出的热还是在有机电致发光光源里面,没有彻底导出。 Notably, because the anode or the cathode member 270 and the heat sink 260 is only in the sealing cover 220 into heat or derived at this time in the organic electroluminescent light source which is not completely derived. 为此,封接盖220中的阳极或阴极散热内件270、 260并非整个散热路径的终点,阳极或阴极散热内件270、 260可通过阳极或阴极散热外件271和261直接连接到封接盖220外面, 可直接与外界大气接触,进一步将热散逸到外界。 To this end, the sealing cover member 270, 260 is not the entire heat radiation path within the end 220 of the anode or cathode dissipation, the anode or cathode cooling member 270, 260 may be connected to the anode or the cathode by a sealing member 271 and the outer heat sink 261 directly outside the cover 220, can be in direct contact with the outside air, the heat dissipation is further to the outside. 本发明的实施例,直接利用阴极材料和阳极辅助材料作为阳极或阴极散热内件270和260。 Embodiments of the present invention, as the anode or cathode 270 and the heat sink 260 directly cathode material and the anode auxiliary materials. 在光刻阳极辅助材料(Cr 或Ag等)时直接形成Cr或Ag等阳极散热内件270和阳极散热外件271;在形成阴极时,利用掩膜直接形成阴极散热内件260和阴极散热外件261。 Cr or the like within the cooling Ag anode member 270 and outer member 271 is formed directly anode dissipation during the lithographic auxiliary anode material (Cr, or Ag, etc.); in forming the cathode, the cathode is formed using a mask directly heat dissipation member 260 and the cathode outer 261. 所述阳极散热部件和所述阴极散热部件由如Al或Cr等的导热系数大于50W/mK的薄膜材料构成;所述阳极散热部件和所述阴极散热部件可由包括Al、 Cr、 Al-Ag合金、Ag、 Mg-Ag合金等金属(薄膜)材料构成。 Cooling said anode member and said cathode member a heat sink, such as Cr, Al or thermal conductivity greater than 50W / mK, the material constituting the film; cooling said anode member and said cathode member may include a heat dissipating Al, Cr, Al-Ag alloy , metal Ag, Mg-Ag alloy (film) material.

在传统的有机电致发光照明光源器件(图l)中,除了IT0为阳极材料和A1为阴极材料,周边都是导热性很差的玻璃基板(导热系数K=1.4-2 W/mK)。 In the conventional organic electroluminescent illumination source device (FIG. L), in addition to A1 IT0 of anode material and cathode material, the glass substrate surrounded by the poor thermal conductivity (thermal conductivity K = 1.4-2 W / mK). 有机电致发光器件所产生的热,向下传递的终点是阳极层ITO和玻璃基板,而向上传递的终点是有机电致发光器件的阴极。 Heat generated organic electroluminescent device, the transmitting end is downwardly ITO anode layer and the glass substrate, and the end of the cathode is passed upwardly organic electroluminescent device. 而常用的阴极材料为金属,包括A1、 Al-Ag合金、 Ag、 Mg-Ag合金等等,其导热系数K 一般都大于160 W/mK,远远大于玻璃基板的导热系数K。 And commonly used cathode material is a metal, including A1, Al-Ag alloy, Ag, Mg-Ag alloy, etc., the thermal conductivity K is generally greater than 160 W / mK, much greater than the thermal coefficient of the glass substrate K. 因此,有机电致发光器件所产生的热会向上传递至有机电致发光器件的阴极。 Thus, heat generated by the organic electroluminescent device will be passed up to the cathode of the organic electroluminescent device. 而根据本发明的一个优选实施方案,于有机电致发光器件周边区域设置有多个散热部件,并直接与阴极相连或通过导热件与其相连,致使有机电致发光器件所产生的热能直接传递出器件本身,从而增加器件稳定性。 According to a preferred embodiment of the present invention, the organic electroluminescent device in the peripheral region is provided with a plurality of heat radiating members, and the cathode is connected directly or via a heat conducting member connected thereto, so that heat energy generated by the organic electroluminescent device is transmitted directly device itself, thereby increasing the stability of the device. 阴极金属的优选厚度大于150nm。 The preferred thickness of the cathode metal is greater than 150nm.
