[background technology]

Electrodeless discharge lamp (being called for short electrodeless lamp) is that comprehensive power electronics, plasma are learned, magnetic material is learned the high light efficiency of representative lighting technology that scheduling theory develops, the new type light source of longevity, high-color rendering future thrust.And there is certain defective in the structural design of existing electrodeless lamp, thereby the heat that its radiator structure adopts the copper post that inner magnet, coil are sent usually exports to the mode that outside aluminum alloy heat sink is finished heat radiation, and along with improving constantly the electrodeless lamp power demand, existing radiator structure can't satisfy the demands, the inner high temperature that produces of the electrodeless lamp of finished product often is difficult to be effectively controlled, thereby bring following problem: 1, the power ascension difficulty of electrodeless lamp, can't make more powerful bulb; 2, the easy Yin Gaowen of electrodeless lamp interior loop and melting ruins, and causes electrodeless lamp to damage and can't continue to use; 3, high temperature easily causes electrodeless lamp operating efficiency to reduce lifetime;

4, electrodeless light color temperature performance is unstable; Not only be accompanied by bigger caloric value when 5, making high-power electrodeless lamp of the same type, and cost is very high; 6, if directly adopt the method that adds the blister copper post, its radiating effect is not only limited, also can increase production cost and product own wt greatly undoubtedly.As seen, existing electrodeless modulated structure is needed improvement side badly to meet the demand of social development.

[summary of the invention]

The purpose of this utility model is to have overcome above-mentioned defective, provides a kind of and adopts heat pipe and in conjunction with copper, the aluminum electrodeless lamp of high-cooling property of high efficiency and heat radiation more.

The purpose of this utility model is achieved in that the electrodeless lamp of a kind of high-cooling property, it comprises external bulb glass housing, heat conductive rod post, magnet, induction coil, holder and heat dissipation base, its improvements are: described heat conductive rod post adopts the heat pipe of hollow structure, the condensation end of heat pipe links to each other with heat dissipation base, and evaporation ends links to each other with magnet and induction coil;

Also be provided with the copper heat-conducting layer between described holder and heat dissipation base, described heat dissipation base is the aluminum heat dissipation base;

Described copper heat-conducting layer area is not less than the holder floor space;

Described heat pipe hollow is equipped with the volatile heat-conducting liquid of low boiling, and its two ends are provided with end cap, and the heat pipe tube wall between end cap is provided with the wick of being made by the capillary porous material.

Than common electrodeless lamp, the beneficial effects of the utility model are to adopt heat pipe to substitute the copper post, strengthened the heat-sinking capability of electrodeless lamp greatly, the radiator structure that adopts copper, aluminium to cooperate in addition, also further strengthened its radiating efficiency, make the electrodeless lamp after improving to break through original Power Limitation, and being difficult for should be overheated and be damaged, longer service life, electrodeless in addition lamp efficiency gets a promotion, electrodeless lamp institute color development temperature is stable and work is more stable, and hollow-core construction thermal conductance supervisor copper post also can make electrodeless lamp more light and handy, is worthy of popularization.

[embodiment]

Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.

As shown in Figure 1, the utility model relates to the electrodeless lamp of a kind of high-cooling property, and it includes external bulb glass housing 1, and housing 1 is connected with holder 4.Be coated with fluorescent material in described housing 1 surface, be provided with the cavity 2 that hollow is used for ccontaining solid-state mercury in it, housing 1 center is provided with cavity, be provided with heat conductive rod 3 in the cavity, heat conductive rod 3 upper ends are provided with magnet 7, be wound with induction coil 8 outside the magnet 7, heat conductive rod 3 lower ends are passed holder 4 and are connected on the heat dissipation base 6.The utility model does not adopt the heat conductive rod 3 of common copper post as electrodeless lamp, but directly adopt heat pipe (the title heat pipe to be arranged, English Heat Pipe) Alloy instead of Copper post, this heat pipe has utilized the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling by branch, be delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.Its guide-tube structure is referring to Fig. 2, heat pipe 3 hollows are equipped with the volatile heat-conducting liquid 301 of low boiling, its two ends are provided with end cap 302, the heat pipe tube wall that end cap is 302 is provided with the wick of being made by the capillary porous material 303, when heat pipe is made, at first negative pressure state is pumped in its hollow inside, charges into suitable liquid then, this boiling point of liquid is low, easily volatilization.The heat pipe tube wall has wick 303, and it is made of the capillary porous material.Heat pipe is an evaporation ends for one section, other one section is condensation end, therefore when one section of heat pipe is heated, liquid in the capillary evaporates rapidly, and steam flows to an other end under small pressure differential, and discharges heat, regelation becomes liquid, liquid flows back to evaporation section along porous material by the effect of capillary force again, and so circulation is more than, and heat can reach an other end by heat pipe one end.And this circulation is carried out fast, and heat can be come by conduction continuously, thereby obtains the capacity of heat transmission considerably beyond any known metal.Therefore, in the utility model, the condensation end of heat pipe 3 links to each other with heat dissipation base 6, and evaporation ends links to each other with magnet 7 and induction coil 8.In addition, for further strengthening the radiating effect of electrodeless lamp, the utility model adopts aluminum heat dissipation base 6, the good heat radiating ability copper product of considering aluminium is then to there being the good capacity of heat transmission, add the same copper heat-conducting layer 5 that connects heat conductive rod 3 in holder 4 and 6 of heat dissipation bases, for guaranteeing better heat radiating effect, these copper heat-conducting layer 5 areas should be not less than holder 4 floor spaces, not only guaranteed bigger heat-conducting area thus, and the copper heat-conducting layer also can be in firm sticking on the aluminum heat dissipation base 6 under the effect of holder 4.

In sum as seen, after adopting heat pipe to substitute the copper post, strengthened the heat-sinking capability of electrodeless lamp greatly, the radiator structure that adopts copper, aluminium to cooperate has in addition also further been strengthened its radiating efficiency, makes that the electrodeless lamp after improving has following advantage:

1, the breakthrough of heat radiation bottleneck makes the more high-power electrodeless lamp of the preparation possibility that becomes;

2, electrodeless lamp is difficult for answering overheated and is damaged longer service life

3, luminous efficiency gets a promotion, and the work of electrodeless lamp each several part is more stable, and cost reduces;

4, because heat pipe is a hollow-core construction, and its quality is far below equal volume copper post, final electrodeless lamp finished product is more light and handy;

5, functional reliability height, institute's color development temperature is stable.

It is to be noted; the utility model is not limited to above-mentioned execution mode; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description in based on technical solutions of the utility model all belong in the protection range of the present utility model.
