Description

Discharge lamp, discharge lamp device, fluorescent lamp and fluorescent lamp device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge lamp, a discharge lamp device, a fluorescent lamp, and a fluorescent lamp device having improved luminous flux up to the end of life.

Conventionally, in the fluorescent lamp as a discharge lamp of this kind, when the temperature of the coolest part in the tube exceeds 40 ° C, the main amalgam or extinction that controls the mercury vapor pressure in the bulb in an appropriate range at the time of normal lighting. Auxiliary amalgam may be used to adsorb suspended mercury in the bulb at the time of light discharge and to release mercury adsorbed at the initial stage of lighting, including during startup.

As this auxiliary amalgam, a bulb-type fluorescent lamp device disclosed in, for example, Japanese Patent No. 2563028 is known. The bulb type fluorescent lamp device described in Japanese Patent Publication No. 2563028 includes a globe in which a bismuth (Bi) -indium (In) amalgam is accommodated in a glass bulb.

Incidentally, since indium has a low melting point of 156 ° C., it is solid at room temperature but becomes a liquid when the fluorescent lamp is turned on and becomes a high temperature. Indium flows in the direction of the support wire which is at a high temperature. For this reason, indium forms an alloy with nickel of a support wire, and has sufficient mercury adsorption capability immediately after manufacture of a fluorescent lamp, but gradually loses the mercury adsorption ability, and the luminous flux rise characteristic at the start-up will fall.

Moreover, the structure of Unexamined-Japanese-Patent No. 61-121252 is known as a structure which prevents indium from flowing in this way. Japanese Laid-Open Patent Publication No. 61-121252 discloses a mesh body in which an inner wire of a filament is coated with indium. The mesh body is coated with indium plating except for the area attached to the inner wire, thereby preventing the molten indium from flowing through the inner wire.

However, as described in Japanese Laid-Open Patent Publication No. 61-121252, when the mesh body is coated with indium plating except for a part of the region, the surface area of the mesh body is not so large. Not only is the plating itself complicated, but the area is large, miniaturization is not possible, and the cost of the mesh body is high.

Moreover, when the area | region which indium is plated on a mesh body becomes small, there exists a problem that there exists a possibility that it may become impossible to ensure the quantity of indium required for the improvement of the luminous flux rising characteristic at the time of starting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a discharge lamp, a discharge lamp device, a fluorescent lamp, and a fluorescent lamp device which can be easily formed and which do not lower the luminous flux rising characteristic until the end of life.

The phosphor film 153 is formed of an active three-wavelength luminescent phosphor in which a rare earth metal having a thickness of 10 μm to 20 μm is added thereto, and a rare gas such as argon and mercury are sealed therein. have.

A stem 154 is formed at an end thereof, and a tubule 155 having a function as an exhaust pipe is welded to the stem 154, and, for example, bismuth (Bi) -indium (In) is exhausted as necessary. ) Main amalgam 156 is stored. This main amalgam 156 adsorbs mercury to indium, bismuth, tin, lead and their alloys to control the mercury vapor pressure in the bulb 152 to an appropriate range.

Further, at the end of the bulb 152, a filament coil 157, which is a thermal cathode coated with an electrospinning material, is supported by a weld 158 as a pair of linear support members as a support wire, and this weld 158 is shown in FIG. As shown in FIG. 23 and FIG. 24, nickel (Ni) 162 is plated and formed in the film thickness of 3 micrometers on the core wire 161 of the copper (Cu) of diameter 0.2mm. One weld 158 is plated with chromium (Cr), which is a material that does not easily cause chemical reaction with indium, to form a coating portion 162, and an auxiliary amalgam 163 is attached to the coating portion 162. It is. In addition, the coating part 162 has a film thickness of about 3 μm, the length L1 is about 15 mm, which is about three times the length of the auxiliary amalgam 163, and the length of the coating part 162 in the longitudinal direction. It is located almost in the center part, and one surface on which the indium 165 of the auxiliary amalgam 163 is coated is supported by welding.

Moreover, this auxiliary amalgam 163 is formed on a flat rectangular stainless metal body 164 having a thickness of about 0.1 mm, a length of about 3 mm, and a width of about 9 mm, and a surface of indium 165 having a thickness of about 5 μm. Plating is formed on. In addition, the auxiliary amalgam 163 adsorbs the floating mercury in the light emitting tube 146 at the time of extinction and releases the mercury adsorbed at the initial stage of lighting, including during startup, to improve the synergistic characteristics. In addition, each weld 158 is connected to the power supply pin 167 of the lighting circuit 144 via the dummet line 166 sealed to the glass of the edge part of the light bulb 152.

When the light emitting tube 146 is turned on, the temperature of the light bulb 152 increases, and the temperature of the auxiliary amalgam 163 increases. If the temperature of the auxiliary amalgam 163 exceeds the melting point of the indium 165, the indium (165) liquefy The liquefaction of the indium 165 causes the indium 165 to move due to the self-weight or surface tension of the indium 165, but the coating 162 of the weld 158 easily reacts with the indium 165. Since it is formed of chromium which is a material which does not produce, indium 165 does not move.

Therefore, the indium alloy is not formed between the weld 158 and the auxiliary amalgam 163, and the mercury adsorption characteristic of the auxiliary amalgam 163 can be suppressed from being lowered, so that the luminous flux rising characteristic at the start can be maintained for a long time. have.

In addition, the coating portion 162 is not limited to chromium, and at least one of zinc (Zn), iron (Fe), aluminum (Al), vanadium (V), lead (Pb), and molybdenum (Mo), and oxides thereof. The same effect can be obtained also by using stainless, and when forming these coating | coated parts 162, what is necessary is just to form by arbitrary methods, such as plating or application | coating.

Further, the width dimension of the covering portion 162 is the axial length of the weld 158 in consideration of the difference in the attachment position on the manufacturing surface of the weld 158 with respect to the covering portion 162 is the auxiliary amalgam 163. Although the width of the coating portion 162 is set to be substantially equal to the diameter of the weld 158 in order to reduce the material cost of the coating portion 162 and prevent the action of the indium 165 from being impeded. It may be formed only on the surface of the auxiliary amalgam 163 connected without sensing.

In addition, a fourteenth embodiment will be described with reference to FIG.

FIG. 25 is an enlarged cross-sectional view of the connection of the auxiliary amalgam of the fourteenth embodiment. In FIG. 25, the sleeve 166 is replaced with the cover 162 in FIG. 22 to FIG. 24. It fits into the weld 158 and connects the auxiliary amalgam 163 to this sleeve 166.

The sleeve 166 is made of stainless steel that does not easily undergo chemical reaction with indium having an outer diameter of about 0.4 mm, an inner diameter of about 0.2 mm, and a length of about 15 mm, and the inner diameter of the sleeve 166 and the outer diameter of the weld 158 Since it is almost the same, the sleeve 166 is covered with the weld 158 by frictional engagement, and spot welding is carried out in order to further secure the adhesion as necessary.

Even in this case, even if the indium 165 is liquefied, the indium 165 does not move because the sleeve 166 is made of stainless steel, which does not chemically react with the indium 165.

Therefore, an indium alloy is not formed between the indium 165 and the sleeve 166, so that the mercury adsorption characteristic of the auxiliary amalgam 163 can be suppressed from deteriorating, and the light beam rising characteristic at the start can be maintained for a long time. have.

In addition, since the sleeve 166 may be sandwiched in the weld 158 in this manner, the manufacturing can be simplified.

In addition, the sleeve 166 is not limited to stainless, and at least among zinc (Zn), chromium (Cr), iron (Fe), aluminum (Al), vanadium (V), lead (Pb), and molybdenum (Mo). The same effect can be obtained even by using these oxides, and is not limited to being located over the entire circumference of the weld 158, and at least part of the arc-shaped arc is cut off if only the portion to which the auxiliary amalgam 163 is connected is formed. It may be.

The metal foil 167 is formed of a molybdenum foil that does not chemically react with a rectangular indium having a thickness of about 3 μm, about 15 mm in length, and about 1 mm in width, and is wound on the weld 158 to be fixed. do.

Also in this case, since the metal foil 167 is made of molybdenum which does not easily cause a chemical reaction with the indium 165 even when the indium 165 is liquefied, the indium 165 does not move.

Therefore, an indium alloy is not formed between the metal foil 167 and the indium 165, so that the mercury adsorption characteristic of the auxiliary amalgam 163 can be suppressed from deteriorating, and the light beam rising characteristic at the start can be maintained for a long time. have.

In addition, since the metal foil 167 may be wound around the weld 158 in this way, manufacture can also be simplified.

The metal foil 167 is not limited to molybdenum and includes at least one of zinc (Zn), chromium (Cr), iron (Fe), aluminum (Al), vanadium (V), and lead (Pb), oxides thereof, Alternatively, the same effect can be obtained by using stainless steel.

In addition, the metal foil 167 does not necessarily need to be wound over the whole circumference of the weld 158, and should just be formed only in the part which contacts the auxiliary amalgam 163, and also assists with respect to the axial length of the weld 158. It is good to form only in the part which amalgam 163 contacts.

Furthermore, a sixteenth embodiment will be described with reference to FIG.

FIG. 27 is an enlarged cross-sectional view of the connection of the auxiliary amalgam of the sixteenth embodiment. In FIG. 27, the weld 158 is replaced with the cover 162 in FIG. 22 to FIG. 24. One end of the metal pillar 168, which is an intermediate member spaced apart from the auxiliary amalgam 163, is welded to the weld 158, and the auxiliary amalgam 163 is welded to the other end of the metal pillar 168 to weld the metal pillar 168. Fix it as a leg.

In the connection, one end of the metal pillar 168 is first welded to the weld 158, and then the auxiliary amalgam 163 is welded and attached to the other end of the metal pillar 168.

The metal pillar 168 is made of molybdenum having a diameter of 0.2 mm in cross section and a round columnar shape having a length of 5 mm, which does not easily cause chemical reaction with indium.

Even in this case, there is not only a 5 mm physical and mechanical gap between the auxiliary amalgam 163 and the weld 158 even when the indium 165 is liquefied, but the metal pillars 168 are in chemical reaction with the indium 165. Since molybdenum is not easily produced, indium 165 does not move.

Therefore, an indium alloy is not formed between the weld 158 and the indium 165, so that the mercury adsorption characteristic of the auxiliary amalgam 163 can be suppressed from deteriorating, and the light beam rising characteristic at the start can be maintained for a long time. have.

In addition, since the metal foil 167 may be wound around the weld 158 in this way, manufacture can also be simplified.

The metal pillar 168 is not limited to molybdenum, and at least one of zinc (Zn), chromium (Cr), iron (Fe), aluminum (Al), vanadium (V), and lead (Pb), and oxides thereof. The same effect can be obtained also by using stainless steel.

In the connection, one end of the metal pillar 168 was first welded to the weld 158, and then the auxiliary amalgam 163 was welded and attached to the other end of the metal pillar 168, but on the contrary, to the auxiliary amalgam 163. One end of the metal pillar 168 may be welded, and then the other end of the metal pillar 168 may be welded to the weld 158.

In addition, the intermediate member that separates the weld 158 from the auxiliary amalgam 163 is not limited to the metal pillar 168, and may be in any shape, and any other material may be used. Is a material that does not easily cause chemical reactions with indium.

Furthermore, a seventeenth embodiment will be described with reference to FIG.

FIG. 28 is a perspective view showing the connection of the auxiliary amalgam of the seventeenth embodiment, which is shown in FIGS. 22 to 24, instead of the covering portion 162 of the weld 158. On the indium 165 of the amalgam 163, a coating portion 171 of chromium which does not easily cause chemical reaction with indium is formed by plating or coating.

The coating portion 171 has a film thickness of about 3 μm, the length is about 3 mm equal to the longitudinal dimension of the metal body 164 of the auxiliary amalgam 163, and the width L2 is 0.2 mm in diameter of the weld 158. It is formed in about 0.5 to 0.6 mm which is about 3 times, and the outer peripheral surface of the weld 158 is connected by the welding to the substantially center of this coating part 171.

Even in this case, even if the indium 165 is liquefied, the indium 165 does not move because the coating portion 171 is chromium which does not easily cause a chemical reaction with the indium 165.

Therefore, an indium alloy is not formed between the weld 158 and the indium 165, so that the mercury adsorption characteristic of the auxiliary amalgam 163 can be suppressed from deteriorating, and the light beam rising characteristic at the start can be maintained for a long time. have.

In addition, even if the weld 158 is linear thin in this way, since the coating part 171 may be formed in the flat elongate form on the auxiliary amalgam 163, it is manufactured compared with forming the coating part in the weld 158. Can be simplified.

In addition, the coating part 171 is not limited to chromium, At least in zinc (Zn), chromium (Cr), iron (Fe), aluminum (Al), vanadium (V), lead (Pb), and molybdenum (Mo). The same effect can be obtained also when using one kind, these oxides, or stainless steel.

In addition, the width dimension of the covering part 171 is set to about three times the diameter of the weld 158 as an adhesion value in consideration of the nonuniformity of the attachment position in the manufacturing surface of the weld 158 with respect to the covering part 171. However, in order to reduce the material cost of chromium and the effect of indium 165, the width of the coating portion 171 may be set to a width substantially equal to the diameter of the weld 158.

Furthermore, an eighteenth embodiment will be described with reference to FIG.

FIG. 29 is a perspective view showing the connection of the auxiliary amalgam of the eighteenth embodiment. In FIG. 29, the chrome coating portion 171 is wound around the metal foil 172 in a ring shape. It was formed.

It winds up around the outer periphery of one end side, and fixes the terminal part of the metal foil 172 by spot welding, and the outer peripheral surface of the weld 158 is connected to the center of this metal foil 172 by welding.

Also in this case, since the metal foil 172 is chromium which does not easily cause a chemical reaction with the indium 165 even when the indium 165 is liquefied, the indium 165 does not move.

Therefore, an indium alloy is not formed between the weld 158 and the indium 165, so that the mercury adsorption characteristic of the auxiliary amalgam 163 can be suppressed from deteriorating, and the light beam rising characteristic at the start can be maintained for a long time. have.

Moreover, even if the weld 158 is linear thin in this way, since the metal foil 172 should just be wound on the auxiliary amalgam 163 in a ring shape, manufacture can be simplified.

The metal foil 172 is not limited to chromium, and is at least one of zinc (Zn), chromium (Cr), iron (Fe), aluminum (Al), vanadium (V), lead (Pb), and molybdenum (Mo). Similar effects can also be obtained by using these oxides or stainless steel.
