【課題を解決するための手段】
請求項１記載の電球形蛍光ランプは、口金を有するカバーと；カバーに取り付けられた仕切体と；仕切体に取り付けられ、管外径が８〜１１mm、ランプ電力が７〜１５Ｗで点灯されるように構成された発光管と；仕切体に取り付けられ、カバーに覆われる点灯回路と；カバー内で発光管と点灯回路との間に形成された１５〜３０cm³の空気断熱層と；を具備しているものである。[0007]
[Means for Solving the Problems]
Self-ballasted fluorescent lamp according to claim 1 is a cover having a ferrule; and a partition member which is attached to the cover; attached to the partition member, the tube outer diameter 8～11Mm, lamp power is turned on at 7~15W A lighting circuit, mounted on the partition, and covered by the cover; a 15-30 cm ³ air insulation layer formed between the light emitting tube and the lighting circuit within the cover; It is equipped.

そして、管外径が８〜１１mm、ランプ電力が７〜１５Ｗで点灯されるように構成された発光管を備えていても、カバー内の発光管と点灯回路との間に１５〜３０cm³の空気断熱層を形成したので、点灯回路への熱的影響と小形化との最適な条件を規定し、点灯回路への熱的影響を低減し、小形化可能とする。空気断熱層が１５cm³以下では十分な断熱効果が得られず、３０cm³以上では大形化する。[0008]
Then, 15 to 30 cm between the tube outer diameter is 8～11Mm, be provided with a configured light emitting tube so as lamp power is turned on in 7～15W, the arc tube in the cover and the lighting circuit ³ The thermal insulation layer is formed, so that the optimum conditions of the thermal influence on the lighting circuit and the miniaturization are specified, the thermal influence on the lighting circuit is reduced, and the miniaturization is possible. When the thickness of the air insulation layer is 15 cm ³ or less, a sufficient heat insulation effect can not be obtained, and when it is 30 cm ³ or more, the size is increased.

請求項１記載の電球形蛍光ランプによれば、管外径が８〜１１mm、ランプ電力が７〜１５Ｗで点灯されるように構成された発光管を備えていても、カバー内の発光管と点灯回路との間に１５〜３０cm³の空気断熱層を形成したので、点灯回路への熱的影響と小形化との最適な条件を規定でき、点灯回路への熱的影響を低減し、小形化できる。[0040]
【Effect of the invention】
According to the self-ballasted fluorescent lamp according to claim 1, the tube outer diameter 8～11Mm, be provided with a luminous tube lamp power is configured to be turned on in 7～15W, the arc tube in the cover Since an air insulation layer of 15 to 30 cm ³ is formed between the lamp and the lighting circuit, it is possible to specify the optimum conditions for the thermal effects on the lighting circuit and miniaturization, and reduce the thermal effects on the lighting circuit, It can be miniaturized.
