Problems solved by technology

[0009] However, in the technology of the above-mentioned patent document 2, the switching situation of the first lighting element (fluorescent discharge container) and the second lighting element (LED) is disclosed, but it does not disclose what kind of control is performed under what circumstances.
[0010] Moreover, in the technique of Patent Document 2, a plurality of second lighting elements are arranged around the first lighting element, so in the night light state in which the second lighting elements are turned on, the first lighting element in the center The problem of uneven lighting caused by shadows
[0011] Furthermore, in the technology of Patent Document 2, since the second lighting element is arranged near the electrode of the first lighting element, there is an inevitable problem of deterioration due to thermal influence.

Embodiment Construction

[0085] As shown in FIGS. 1 and 2 , the bulb-shaped fluorescent lamp device includes a fluorescent lamp body 1 , a lighting circuit 2 , a cover 3 (cover), a lamp cap 4 , a lamp cover 5 (globe) and a partition 6 . The fluorescent lamp main body 1 includes a translucent discharge vessel 1a as a first light emitting part, a phosphor layer, a discharge medium, an electrode 1b, a light emitting diode D53 as a second light emitting part, and the like. In addition, external parts such as the cover 3 , lamp cap 4 , and lampshade 5 are called the device main body, and the internal fluorescent lamp part is called the fluorescent lamp main body 1 .

[0086] The light emitting diode D53 is built in the lampshade 5, and is arranged at the approximate center of the lampshade 5 or the fluorescent lamp body 1. As shown in FIG. The light-emitting diode D53 lifts its bottom from the wiring board 2a so that it is separated from the end electrode 1b of the light-transmitting discharge vessel 1a, a...

Abstract

A bulb type fluorescent lamp apparatus is disclosed to adjust the light under a low illumination without nonuniform lighting. The bulb type fluorescent lamp apparatus comprises: a bulb type apparatus main body disposed on the lamp head (4), which is supplied with AC power under the control of wall switch (SW); a main body (1) of the fluorescent lamp arranged in the apparatus; a light emitting diode circuit (LED) disposed in the main body of the apparatus; and a control circuit (AC power supply trip time detecting circuit (ACPODC) and inverter oscillation stopping circuit (IOSC)), detecting the AC power supply state controlled by the wall switch (SW), and controlling the fluorescent lamp main body and the light emitting diode circuit (LED) based on the power supply state.

Description

technical field [0001] The present invention relates to a bulb-shaped fluorescent lamp unit. Background technique [0002] Electricity-saving light bulb-shaped fluorescent lamp devices equipped with E26 bases that can be attached to sockets for incandescent lamps such as households and have built-in inverters are commercialized. [0003] Most of the previous bulb-shaped fluorescent lamp devices only perform any operation of lighting or not lighting, so there are many requirements for dimming. [0004] As such a prior art, there has been proposed, for example, a function of switching the brightness of the fluorescent lamp body by turning on / off a wall switch to turn on / off a commercial power supply (hereinafter referred to as AC power supply), that is, step dimming. function (for example, refer to Patent Document 1). [0005] In the technique of Patent Document 1, stepwise dimming up to about 60% to 70% of the normal lighting state can be performed by a single fluorescent l...
