    • In the fluorescent lamp of the present invention, a fluorescent layer and a reflection layer are formed on an inner surface of a tubular glass bulb such that the reflection layer is formed between the glass bulb and the fluorescent layer, and the open angle of opening portions formed in the fluorescent layer and the refection layer is made smaller than that formed in the external electrode. Thereby, reflection efficiency is improved, thereby making it possible to increase the amount of light with the same power consumption. Since the independent reflection layer is formed and the external electrode does not need to serve as a reflector, flexibility is given to the setting of the area of the external electrode, whereby power consumption is set freely.
    • 在本发明的荧光灯中,在管状玻璃灯泡的内表面上形成荧光层和反射层,使得反射层形成在玻璃泡和荧光层之间,开口部的开口角度 形成在荧光层中并且使反射层比在外部电极中形成的更小。 从而,提高了反射效率,从而能够以相同的功率消耗增加光量。 由于形成独立的反射层并且外部电极不需要用作反射器,所以赋予外部电极的面积的设定的灵活性,由此自由设定功耗。

    • A fluorescent lamp (1) includes a tubular glass bulb (2), an internal electrode (5) within the tubular glass bulb (2), a fluorescent layer (4) formed on an inner surface of the glass bulb (2), an external electrode (3) provided on an outer surface of the glass bulb (2), and a covering glass tube (6) is disposed over the total length of the internal electrode (5). The fluorescent lamp (1) further includes a fluorescent layer (7) disposed on the outer surface of the glass tube (6). The fluorescent lamp (1), as configured above, makes it unnecessary to form the internal electrode into a coil, and absorbs the difference in thermal expansion coefficients. This prevents the internal electrode (5) from resonating with vibrations from the outside and prevents contact of the fluorescent layer (4) by the internal electrode (5).
    • 荧光灯(1)包括管状玻璃灯泡(2),管状玻璃灯泡(2)内部的内部电极(5),形成在玻璃灯泡(2)的内表面上的荧光层(4) 设置在玻璃泡(2)的外表面上的外部电极(3),并且在内部电极(5)的整个长度上设置覆盖玻璃管(6)。 荧光灯(1)还包括设置在玻璃管(6)的外表面上的荧光层(7)。 如上所述,荧光灯(1)不需要将内部电极形成为线圈,并且吸收热膨胀系数的差异。 这防止内部电极(5)与来自外部的振动共振,并且防止荧光层(4)被内部电极(5)接触。
