Embodiment
Below, the execution mode of present invention will be described in detail with reference to the accompanying related ceramic metal helide lamp.In addition, in figure, for the identical reference marks of identical element annotation, the repetitive description thereof will be omitted.
[current ceramic metal helide lamp and restart characteristic]
The figure of the structure of the ceramic metal helide lamp 10 of Fig. 1 is the current inclosure of explanation 2 luminous tubes.As shown in Figure 1, lamp 10 seals in the inside of ectosphere 22 luminous tube 4-1,4-2.An engaged at end of ectosphere 2 has lamp holder 6.Each luminous tube 4-1,4-2 is supported on precalculated position by support 8.
Luminous tube 4-1,4-2 are that light-transmittance ceramics is made, and the maximum outside diameter of illuminating part is 15.2mm, and the beeline of outer surface is 10.8mm.Like this, 2 luminous tubes are adjacent, with nearer apart from spread configuration.
Ectosphere 2 is made such as printing opacity hard glasss such as Pyrex.Ectosphere 2 forms the BT shape of the neck that is connected with lamp holder of the top of central portion with maximum caliber, the downside shown in figure and upside.Ectosphere 2 has the ground-glass appearance that transparent type ectosphere that the direct straight line of the light that makes Self-luminous tube 4 sees through and the inside be white in color and diffusion type ectosphere that light is seen through with diffusion to a certain degree.
In present specification, " startup " gives directions the luminous tube of bright low-temperature condition (that is, the external air temperature around the state of lamp and common lamp, room temperature etc. are in equal state)." restart " lamp that refers to lighting and extinguish once, and then light the luminous tube of the fully not cooling condition of high temperature.The lamp of this condition of high temperature such as the lamp that can enumerate following situation etc.: again light luminous tube after extinguishing in the short time, light the adjacent luminous tube in the extinguishing of luminous tube heating in being lit.
And in the ceramic metal helide lamp of having enclosed 2 luminous tubes, the luminous tube in lighting is called " side luminous tube ", and the luminous tube in extinguishing is called " the opposing party's luminous tube ".
Enclosing 2 luminous tube 4-1, in the ceramic metal helide lamp 10 of 4-2, in the situation that lamp is lighted the luminous tube (in extinguishing) that the life-span of operation or a side's luminous tube (in lighting) lights adjacent the opposing party after using up again at once after extinguishing, restarting the needed time needs about 8 minutes usually.
The inventor etc. think that the temperature that the heat of the luminous tube that carrys out My World is enclosed in the gas in the opposing party's luminous tube in causing raises, and becomes the reason that can't restart in the short time.In addition, in in the past high-pressure sodium lamp etc., owing in ectosphere, being vacuum state, so the amount of thermal conduction that the thermal radiation between 2 luminous tubes causes is considerably less, but in the ectosphere due to current ceramic metal helide lamp, be full of predetermined inert gas (argon Ar, nitrogen N are typically arranged), so amount of thermal conduction is large, make in the short time restart more difficult.In addition, air pressure is in the scope of 20～70kPa.If discontented 20kPa,, when a side luminous tube leaks, produce electric discharge in ectosphere, the opposing party's luminous tube point is not worked.If surpass 70kPa, ectosphere likely is difficult to sealing.
[realization that the shortening of reboot time and moment restart]
The inventor etc. are in the 1st stage, and the target of setting is for to shorten to half the time by reboot time, namely about 4 minutes.In addition, in the 2nd stage, the target of setting is for shortening in 1 minute.
As the 1st research, to have inquired into when restarting, the pulse voltage that applies by rising shortens reboot time and realizes that moment restarts.
Fig. 2 illustrates in lamp shown in Figure 1, the curve chart of the pulse voltage while raising successively pulse voltage Vp-reboot time characteristic RS-A.The output of this lamp is 190W, uses now pulse voltage 2.3kV.In addition, stipulated that the withstand voltage of lamp is as product specification.Withstand voltage is determined by the withstand voltage of lamp holder, the distance between the different potentials conductor etc.In the lamp for general lighting with lamp holder as shown in Figure 1 (that is, the lamp beyond the special purposes such as the headlamp of motor vehicle), generally withstand voltage is about 5.0kV.Therefore, consider 10% surplus, pulse voltage Vp is changed between 2.3～4.5kV, obtain reboot time t.
According to the result of Fig. 2, understood fully following item.
(1) while pulse voltage Vp being elevated to 3.5～4.5kV, reboot time t approximately reduces to half.
(2) reboot time of pulse voltage 2.3kV is about 8 minutes, if but use some means that it was become about 4 minutes, as long as describe so same characteristic, reboot time t was shortened in 1 minute.
The reboot time of the lamp of 1 luminous tube is more than 15 minutes.Reboot time in the situation that 2 luminous tubes are alternately lighted is about 8 minutes.Be several seconds the start-up time of the lamp of low-temperature condition (room temperature).Therefore, in the situation of 2 luminous tubes, if the temperature of the luminous tube in extinguishing can be risen, be suppressed to below current half, can expect to make the reboot time of pulse voltage 2.3kV to become about 4 minutes.
Therefore, as the 2nd research, the means that the temperature of the luminous tube of the opposing party in suppressing to extinguish rises have been inquired into.Its result, the luminous tube of the side in lighting and extinguish in the opposing party's luminous tube between heat shield component (also referred to as " thermal component ") is set.The parts that have good heat dispersion by configuration are as heat shield component, and heat shield component makes the thermal diffusion of the luminous tube of My World, reduce to the conduction of the opposing party's luminous tube or stop heat to focus on the opposing party's luminous tube.
In addition, this heat shield component is owing to being configured between luminous tube, so need to have light transmission.As the material of this light transmission heat shield component, for example, can use transparency silica glass.But, be not limited to this.
Fig. 3 is the curve chart that the effect of light transmission heat shield component is shown.Pulse voltage-reboot time characteristic RS-A(uses ◆ expression) be the situation that there is no light transmission heat shield component illustrated in fig. 2, pulse voltage-reboot time characteristic RS-B(represents with) be the situation that has configured suitable light transmission heat shield component.
In the relation of characteristic RS-A and characteristic RS-B, the shortening amount of the reboot time that the configuration by the light transmission heat shield component causes represents with Tt, and the shortening amount of the reboot time that causes by the rising pulse voltage represents with Tv.
Under pulse voltage 2.3kV, characteristic RS-A reboot time is about 8 minutes, but by configuration light transmission heat shield component between 2 luminous tubes, characteristic RS-B reboot time can shorten to below 4 minutes.And, by the pulse voltage 2.3kV that raises successively, under pulse voltage 2.5～4.5kV, reboot time can be shortened in 3 minutes, and then, under pulse voltage 3.0～4.5kV, reboot time can be shortened in 1 minute.
