    • A compact self-ballasted fluorescent lamp (10) which is equivalent to a typical light bulb is provided. The self-ballasted fluorescent lamp (11) induces a cover (14), a ballast (16), an arc tube (18), a base (12) and a globe (17) and formed into a shape whose outline dimensions are nearly identical to the standard dimensions of a typical light bulb. The arc tube (18) is comprised of a plurality of U-shaped bent bulbs (31) which have an inner tube diameter ranging from 6 to 9 mm and arranged in parallel with one another. Having a bulb height ranging form 50 to 60 mm and a discharge path from 400 to 500 mm, the lamp power is 16 to 23 W. An envelope (19) comprising the cover (14)and the globe (17) has a height ranging from 110 to 125 mm including the height of the base (12). As single lead wire (copper-weld) (54) is sealed with the pinch seal portion (45b,45c) at position away from the connecting tube (36) of the bulb (31), the thermal effect to which the copper-weld wire (54) is subject when connecting the tubular bodies (33a, 33b, 33c, 33d) with the connecting tube (36) is reduce and cracks generated on the pinch seal portion (45) which is the sealed point, as a result of the copper-weld wire (54) heated to a high temperature can be prevented and the yield can be improved.
    • 提供等效于典型灯泡的紧凑型自镇流荧光灯(10)。自镇流荧光灯(11)引导盖(14),镇流器(16),电弧管(18), 底座(12)和球形体(17),并且形成为外形尺寸几乎与典型灯泡的标准尺寸相同的形状。 电弧管(18)由多个U形弯管(31)组成,其内管直径范围为6至9mm并彼此平行。 具有50至60mm的灯泡高度和400至500mm的放电路径,灯功率为16至23W。包括盖(14)和灯罩(17)的灯罩(19)的高度范围 从110到125mm,包括基座(12)的高度。 由于单引线(铜焊)(54)在夹紧密封部分(45b,45c)处远离灯泡(31)的连接管(36)的位置密封,铜焊 当连接管体(33a,33b,33c,33d)与连接管(36)相连接时,线(54)被挤压,作为密封点的夹紧密封部分(45)产生的裂纹,由于 可以防止加热到高温的铜焊丝(54),并且可以提高成品率。

    • The electrodes of a discharge lamp are prevented from reaching damaging temperatures which tend to occur when the discharge lamp is near the end of its useful life. The combination of a discharge lamp and luminaire contribute to ensuring the discharge lamp remains unilluminated when nearing the end of its useful life to prevent high temperature damage. Load circuit characteristics are set to provide low release voltage and high short-circuit current during full-intensity illumination, and high release voltage and low short-circuit current during dimmed operation. The discharge lamp operating in a dimmed mode at the end of its useful life is switched to full-intensity illumination mode to ensure the discharge lamp becomes unilluminated. This configuration prevents high temperatures at the electrodes from damaging the glass bulb, base, socket and other components of the discharge lamp and luminaire.
    • 放电灯的电极被防止达到当放电灯接近其使用寿命结束时倾向于发生的有害温度。 放电灯和灯具的组合有助于确保放电灯在使用寿命结束时保持未点亮,以防止高温损坏。 负载电路特性设置为在全强度照明期间提供低释放电压和高短路电流,并且在调光操作期间具有高释放电压和低短路电流。 在使用寿命结束时以调光模式运行的放电灯切换到全强度照明模式,以确保放电灯未亮起。 这种配置可防止电极的高温破坏放电灯和灯具的玻璃灯泡,基座,插座和其他部件。
