本考案は、蛍光ランプ改良に関し、特に光拡散
被膜を備えた外管と外管内に複数の屈曲した内管
を有した蛍光ランプの品質向上に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in fluorescent lamps, and more particularly to improvements in the quality of fluorescent lamps having an outer bulb with a light-diffusing coating and a plurality of bent inner tubes inside the outer bulb.

う欠点があつた。 For example, as described in Japanese Unexamined Patent Publication No. 54-44370, a plurality of bent inner parts have a plurality of electrodes on a stem, surround each electrode, seal one end, and have the other end near the sealed part. Fluorescent lamps with a tube and an outer tube sealed with a stem using a conventional method are equipped with a light-diffusing coating on the inner surface of the outer tube to improve the glare of the light emitted from the inner tube, but in actual use, the luminous flux is The disadvantage was that it decreased.

光ランプを提供することにある。 Therefore, the purpose of the present invention is to increase the luminous flux of the entire lamp by reflecting light in the stem direction toward the outer tube bulb in a fluorescent lamp having an outer tube equipped with a light-diffusing coating and a plurality of bent inner tubes inside the outer tube. The purpose of the present invention is to provide a light bulb-shaped fluorescent lamp.
上記目的を達成するため、本考案においては、
前述の電球形蛍光ランプにおいて、ステム面へ白
色の絶縁性を有する反射板を備えたことを特徴と
する。 In order to achieve the above purpose, in this invention,
The above-mentioned compact fluorescent lamp is characterized in that a white insulating reflector is provided on the stem surface.
係る特徴的な構成によつて、ランプ全体の光束

安定器の信頼性向上にもなる。 In the figure, a white insulating reflector plate 3 is provided between the lower part of the flare stem 4 and the ballast storage case 2, and by reflecting the light from the downward direction of the flare stem 4 toward the outer tube 9 bulb, the luminous flux of the lamp can be changed from It has the effect of improving by 10%. Further, the reflector plate 3 prevents the influence of heat on the ballast due to a rise in the temperature of the lamp, thereby improving the reliability of the ballast.
