Description

一种外电极平板荧光灯 External electrode flat fluorescent lamp 技术领域  Technical field
本发明涉及一种外电极平板荧光灯。  The invention relates to an external electrode flat fluorescent lamp.
背景技术Background technique
现有低压气体放电荧光灯（简称荧光灯）是普通照明的光源，这种类型荧光灯的寿命取决于灯丝电极的寿命，为了延长荧光灯的寿命，现有技术一直在解决如何增加灯丝上的电子粉量以增加寿命和通过灯丝预热启动方式增加灯丝的开关次数，但效果不佳，特别是紧凑型荧光灯，一般产品寿命在10000小时，开关次数在10000次左右；在当作调光灯使用时，灯丝电极寿命极短。The existing low-pressure gas discharge fluorescent lamp (abbreviated as fluorescent lamp) is a light source for general illumination. The life of this type of fluorescent lamp depends on the life of the filament electrode. In order to prolong the life of the fluorescent lamp, the prior art has been solving how to increase the amount of electronic powder on the filament. Increase the life and increase the number of times the filament is switched by the filament preheating start mode, but the effect is not good, especially the compact fluorescent lamp, the general product life is 10000 hours, the switching times are about 10000 times; when used as a dimming lamp, the filament The electrode life is extremely short.
外电极平板荧光灯的优势在于：1、寿命长，由于电极没有灯丝，解决了现有荧光灯灯丝电极存在的寿命短、开关冲击次数低的问题，外电极荧光灯电极是在玻璃灯板外电极位置涂覆石墨等导电材料形成的，设计上电极寿命可达灯用材料的寿命，如玻璃的寿命、荧光粉的寿命，特别是外电极荧光灯的开关次数实验数字已经达到500万次，电极还是完好无损。2、光效高，光效一般有两个概念：a、光发出端，是指光源效率，b、光接受端，是指被照面被照射的程度，称照明效率；光源经历了点光源（如白炽灯）、线光源（如直管荧光灯）到面光源（平板灯）的过程，由于光接受端被照面被照射的场所一般要求的是平面照明效果，如天花灯照明效果，因此，点光源和线光源都必须通过灯具的二次配光转化实现平面照明，这个转化过程使得点光源、线光源的光效降低了许多，如光源效率为65LM/W的荧光灯通过灯具的二次配光后，照明效率降低到40-50LM/W，而平板灯的光源光效与照明光效是一致的，一般达到50LM/W。3、光品质好，平板灯由于发光面积大，灯光柔和，无眩光，是高质量照明的要求。因此，外电极荧光灯被认为是继白炽灯、荧光灯、无极灯和LED之后的又一种革命性新光源。The advantages of the external electrode flat fluorescent lamp are as follows: 1. The long life is long. Because the electrode has no filament, the problem that the existing fluorescent filament electrode has short life and low switching impact is solved, and the external electrode fluorescent lamp electrode is coated on the outer electrode position of the glass lamp plate. It is formed by conductive materials such as graphite. The life of the electrode can reach the life of the lamp material, such as the life of the glass and the life of the phosphor. In particular, the number of switching times of the external electrode fluorescent lamp has reached 5 million times, and the electrode is still intact. . 2, high light efficiency, light efficiency generally has two concepts: a, light emitting end, refers to the light source efficiency, b, light receiving end, refers to the extent to be illuminated by the illuminated surface, called lighting efficiency; the light source has experienced a point source ( For example, incandescent lamps, line sources (such as straight tube fluorescent lamps) to surface light sources (flat lamps), because the light receiving end is illuminated by the surface of the surface generally requires planar lighting effects, such as ceiling lighting effects, therefore, Both the light source and the line source must be planarly illuminated by the secondary light distribution of the luminaire. This conversion process reduces the light efficiency of the point source and the line source, such as the secondary light distribution of the fluorescent lamp with a source efficiency of 65 LM/W through the luminaire. After that, the illumination efficiency is reduced to 40-50LM/W, and the light source efficacy of the panel lamp is consistent with the illumination efficacy, generally reaching 50LM/W. 3, good light quality, flat light due to large light-emitting area, soft lighting, no glare, is the requirement of high-quality lighting. Therefore, the external electrode fluorescent lamp is considered to be another revolutionary new light source after incandescent lamps, fluorescent lamps, electrodeless lamps and LEDs.
如图1所示，现有的外电极平板荧光灯的放电管1布置都为平行分布，端部圆弧形连接，电极2平行分布在放电管的两边最外侧。由于平板灯的玻璃板为满足产品性能要求，厚度要求越薄越好，但薄玻璃板强度也越差，在平板灯的制造过程中如放电管成型、玻璃板之间的高温封结等，薄玻璃板容易变形，变形产生的应力客观存在灯产品中，而产品在点灯过程存在灯板发热温度高，特别是灯板温度不均和温度梯度大，会使灯产品中应力加大，容易造成在点灯过程出现板裂的质量问题。由于目前的平板荧光灯的放电管布置方式为平行分布，在使用过程中产生了周向方向的温度不均和径向方向温度梯度大，特别是以中心为对称结构的如圆形平板灯，这种放电管的平行布置结构产生的裂板现象非常严重，对外电极荧光灯产品长寿命产生严重影响；由于放电管的平行布置使得不发光的电极处于灯板的外部两侧，特别是圆形结构的平板灯，造成光在灯板的周向分布不均，造成平板灯在使用中有安装方向要求。As shown in FIG. 1, the discharge tube 1 of the conventional external electrode flat fluorescent lamp is arranged in parallel, and the ends are connected in a circular arc shape, and the electrodes 2 are arranged in parallel on the outermost sides of the discharge tubes. Since the glass plate of the flat lamp meets the performance requirements of the product, the thickness is required to be as thin as possible, but the strength of the thin glass plate is also worse. In the manufacturing process of the flat lamp, such as the formation of the discharge tube and the high temperature sealing between the glass plates, The thin glass plate is easily deformed, and the stress generated by the deformation is objectively present in the lamp product, and the product has a high heating temperature of the lamp plate during the lighting process, especially the uneven temperature of the lamp plate and the large temperature gradient, which makes the stress in the lamp product increase, and is easy. Causes quality problems in the cracking process during lighting. Since the arrangement of the discharge tubes of the current flat fluorescent lamps is parallel, the temperature unevenness in the circumferential direction and the temperature gradient in the radial direction are large during use, especially in the form of a circular flat lamp with a symmetrical structure at the center. The parallel arrangement of the discharge tube is very serious, and the long life of the external electrode fluorescent lamp product is seriously affected; due to the parallel arrangement of the discharge tube, the non-emitting electrode is on the outer side of the lamp plate, especially the circular structure. The flat light causes uneven distribution of light in the circumferential direction of the light board, which causes the flat light to have a mounting direction requirement in use.
中国实用新型专利201020225298.3号的说明书附图公开了一种平板荧光灯的结构，如图2所示，该荧光灯玻璃板外形为八角形，其上放电通道1为平行分布，端部为圆弧型连接结构，电极2设置于放电通道1两端。该结构的平板荧光灯就存在上述的板裂及光照不均的问题。The specification of the Chinese utility model patent 201020225298.3 discloses a structure of a flat fluorescent lamp. As shown in FIG. 2, the fluorescent glass plate has an octagonal shape, and the discharge channels 1 are parallel and the ends are arc-shaped. Structure, the electrode 2 is disposed at both ends of the discharge channel 1. The flat fluorescent lamp of this structure has the above problems of plate cracking and uneven illumination.
有鉴于此，本发明人针对现有技术的缺陷深入研究，并有本案产生。In view of this, the inventors have intensively studied the defects of the prior art, and have produced the present case.
