Description

  The present invention relates to a bulb-type fluorescent lamp having a cover body and a globe.

  A bulb-type fluorescent lamp is composed of an arc tube and globe mainly composed of a glass material, a lighting device mainly composed of metal and resin, a resin cover body that accommodates these, and a metal base that is an electric power receiving unit. ing. For this reason, it is very troublesome and difficult to separate the light bulb-type fluorescent lamps that are discarded due to their lifetimes into different materials.

  In recent years, various types of recycling have been performed from the viewpoint of the global environment. However, in the light bulb-type fluorescent lamp as described above, it is very time-consuming to separate each constituent material. In particular, since the glove is firmly fixed by a connecting agent such as silicone resin in a slight gap where the edge of the cover body and each other overlap to prevent falling during use and separation from the cover body, It was not easy to separate the glove and the cover member.

  In addition, in the bulb-type fluorescent lamp having a light emitting tube and a lighting device for lighting the light emitting tube, and a cover body having a base for housing the lighting device, an unevenness is formed at a connection portion between the cover body and the globe attached with the light emitting tube, The unevenness was fitted, and the glove could be attached and detached arbitrarily (see, for example, Patent Document 1).

A technique for fixing or separating the connection between the cover body and the globe by screwing is also known (see, for example, Patent Document 2).

  Hereinafter, embodiments of a light bulb shaped fluorescent lamp of the present invention will be described with reference to the drawings.

  FIG. 1 is a side view of a bulb-type fluorescent lamp showing a first embodiment. FIG. 2 is a partially enlarged sectional view showing the first embodiment of the present invention.

  The bulb-type fluorescent lamp includes a cover body 20 having a base 10, a lighting device 30 housed in the cover body 20, a glass globe 40 formed of a light-transmitting glass material, and the glass globe 40 And an arc tube 50 accommodated therein. And the outer periphery comprised from the glass globe 40 and the cover body 20 is formed in the external appearance which approximates the standard dimension of the incandescent lamp of rated power 60W. That is, the lamp length including the base 10 is about 98 to 123 mm, and the diameter, that is, the maximum outer diameter of the glass globe 40 is about 55 to 60 mm. In the following description, the base 10 side is the upper side and the glass globe 40 side is the lower side.

  The cover body 20 is formed of a heat-resistant synthetic resin, such as polybutylene terephthalate (PBT), and is formed in a substantially conical shape that expands toward the arc tube 50.

  The glass globe 40 is formed of a glass material such as transparent or light diffusing milky white with a smooth curved surface that is almost the same shape as the glass bulb of the incandescent bulb, and the opening 41 of the glass globe 40 has a cover. The body 20 has an opening having substantially the same diameter as the opening 21 at the lower end.

  The circuit board 31 constituting the lighting device 30 housed in the cover body 20 is arranged horizontally, that is, perpendicular to the longitudinal direction of the arc tube 50. A plurality of electronic components 32 are mounted on both surfaces of the circuit board 31, that is, the upper surface on the base side and the lower surface on the arc tube 50 side, and an inverter circuit (high frequency lighting circuit) that performs high frequency lighting is configured. The circuit board 31 has a substantially disc shape, and a pair of lead wires (not shown) led out from the circuit board are electrically connected to the arc tube 50.

  In the arc tube 50, several bulbs 51 having substantially the same shape, for example, three bulbs 51 are arranged at predetermined positions and are sequentially connected by a communication tube to form a single discharge path. An electrode made of a filament coil or the like (not shown) is provided at the portion, and the electrode is connected to four lead wires led out from the arc tube 50 to the outside. Each bulb 51 has an inner surface coated with a three-wavelength light emitting phosphor film, and a rare gas such as argon and mercury are sealed inside.

  The arc tube 50 is attached to a holder 60 (partition plate). That is, the holder 60 includes a disk-shaped substrate portion (not shown), the arc tube end is inserted into an attachment hole formed in the substrate portion, and the arc tube 50 is held by the connecting member such as silicon. After being fixed to 60, the cover body 20 is fitted inside.

  Moreover, the glass globe 40 and the cover body 20 lower end opening 21 have a viscosity of about 10 to 500 Pa · s, which is substantially the same diameter as the globe 40 and the cover body opening 21, a relatively high light transmittance, and a hardness of 20 to 40 JISA. By applying silicon resin 70 to a height of about 0.5 to 5 mm around the periphery of the opening, the two are fixed to each other.

  As a method of separating the globe 40 and the cover body 20 of such a bulb-type fluorescent lamp, the globe 40 is cut by a laser or a knife with the laser 40 or a cutting tool about the center of the silicon resin 70 as a connecting member interposed around the opening of the globe 40 and the cover body 20. And the cover body can be easily separated.

  Next, a second embodiment will be described with reference to FIG. In addition, the same code | symbol is attached | subjected about the same structure as 1st embodiment, and the overlapping description is abbreviate | omitted.

  In the light bulb shaped fluorescent lamp of this embodiment shown in FIG. 3, the cover body opening 21 is formed larger than the globe opening 41, and the opening 41 of the globe 40 is inserted into the cover body opening 21. The gap between the cover body 20 and the globe 40, that is, the periphery of the inner wall of the cover body 20 and the outer wall of the globe 40 is filled with the silicon resin 70. Then, an annular separation member formed of a stainless steel plate having a thickness of 0.5 mm and a width of 5 mm, which is larger than the globe opening diameter and smaller than the cover body opening diameter, is interposed in the overlapping gap between the globe 40 and the cover body 20.

  Separation of the cover body and the globe 40 of the bulb-type fluorescent lamp of the present embodiment is performed by heating the annular separation member interposed around the opening of the globe 40 and the cover body 20, and the silicon resin 70 is heated and softened. Later, the cover body and the globe 40 can be easily separated by rotating and separating one of the globe 40 and the cover body 20 side.

  As described above, according to the bulb-type fluorescent lamp of the present embodiment, the globe 40 and the cover body 20 firmly fixed by the silicon resin 70 can be easily separated, and the generation of waste and the like can be suppressed. Effective use.

  FIG. 4 is an exploded view showing the third embodiment. In the same manner as in the bulb-type fluorescent lamp of the second embodiment shown in FIG. 3, a wavy metal wire 43 is attached to the inside of a silicon resin 70 as a connecting member filled between the globe 40 and the cover body 20. It is. Furthermore, one end of the metal wire 43 extends to the base 10 side. Note that the metal wire extending into the base is supported by caulking when the base 10 is attached to the cover body 20 in a state of being insulated by a silicon tube (not shown).

  As described above, according to the bulb-type fluorescent lamp of the present embodiment, the base 10 is removed when the lamp is discarded, and the metal wire 43 is drawn out from the cover body 20 base side opening, and is interposed over the globe 40 and the cover body 20 periphery. The metal wire 43 can be easily separated by pulling it out.

  In addition, since the globe 40, the cover body 20, and the holder 60 are close to each other in the miniaturized bulb-type fluorescent lamp, the silicon resin 70 that fixes the cover body 20 and the globe 40 is pressed against each other by the joint pressing. There are cases where it is difficult to separate the globe 40 and the cover body 20 by entering between members other than the body 20. In such a case, as shown in FIGS. 5A and 5B, the wiring of the lead wire 43 as the separating member can be interposed between the portions to be separated.

  FIG. 5 is a partially enlarged sectional view of a light bulb shaped fluorescent lamp according to a fourth embodiment of the present invention. FIG. 5A shows that a lead wire 43 as a separating member is interposed around the gap between the cover body 20 and the holder 60 and the gap between the cover body 20 and the holder 60 and the gap between the globe 40 and the holder 60 in addition to the gap between the globe 40 and the cover body 20. It is a thing. That is, by sharing one connection method with each other, a plurality of joining parts can be separated by one type of separation work.

  However, since the light bulb-type fluorescent lamp is compactly configured, the gap between the individual parts is very narrow, and when using silicon 70 having fluidity, the silicon resin 70 is pressed by the pressure when connecting the parts to each other. In order to enter the narrow gap, it is difficult to interpose the separating means in the narrow gap. In such a case, as shown in FIG. 5B, the separation band 71 in which the lead wire 43 as the separation means is interposed while the silicon 70 is formed in a band shape is used by utilizing the adhesiveness of the silicon resin 70. After being temporarily fixed to the fitting part of the fitting part, an assembling operation and a separation operation can be efficiently performed by filling the bonding silicon resin and fixing them together. If necessary, the silicon can be partially peeled off and only the lead wire 43 can be interposed.

  Next, the lighting fixture which is the 1st Embodiment of this invention is demonstrated using FIG. FIG. 6 is a schematic cross-sectional view showing an embodiment of the lighting fixture of the present invention. In the figure, 81 is a bulb-type fluorescent lamp, and 80 is an embedded lighting fixture body. The instrument body 80 includes a base 82 and a reflector 83.
