Description
Affiliated technical field
The utility model relates to a kind of PAR lamp, particularly relates to the PAR lamp that the simple metal halide lamp of a kind of anti-gas-leak and technology is made light source.
Background technology
In the prior art, the PAR lamp that metal halide lamp is made light source has higher luminous efficiency because of the PAR light fixture than halogen lamp as light source, therefore has more energy saving, thereby more and more receives an acclaim.The PAR lamp that metal halide lamp is made light source generally comprises on the lead-in wire at Lamp cup, bowl cover, arc-tube, the arc-tube two ends of lamp holder, inner surface belt reflectance coating, the support parallel with arc-tube, the support and is used for heat insulation earthenware and molybdenum foil, wherein, the lead-in wire of support and arc-tube lower end is fixing as two positions welding that feet and outer lead pass mutually insulated on through hole on Lamp cup and the lamp holder end that lamp holder is connected and the lamp holder, and with the space around white clay filling bracket, lead-in wire are in the lamp holder end of Lamp cup, to strengthen the installation stability of arc-tube.This PAR lamp weak point is: because the interior palpus of Lamp cup and bowl cover is filled inert gas or vacuumized, therefore Lamp cup is connected the mode of production that must adopt the fire envelope so that form seal cavity in the Lamp cup with bowl cover, but this mode of production need adopt special fire envelope equipment, Lamp cup and bowl cover are carried out the high temperature welding to seal, adopt at the cup pin simultaneously and can cut down material and glass capsulation as being electrically connected, also need connect exhaust and the sealed-off that blast pipe carries out Lamp cup at the cup pin simultaneously.This shows that this technology, production procedure are long, the difficulty and the cost of processing technology have been increased on the one hand, comprise equipment cost and technology cost, also influenced the useful life of PAR lamp on the other hand, in case there are damage, cracking, gas leakage in Lamp cup or bowl cover or both joint portions, then whole PAR lamp had just lost efficacy.
The utility model content
The purpose of this utility model is exactly to make the PAR lamp of light source for the metal halide lamp that provides a kind of anti-gas-leak and simplified processing process, reduce cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of metal halide lamp is made the PAR lamp of light source, comprise lamp holder, the Lamp cup of inner surface belt reflectance coating, bowl cover, arc-tube, the arc-tube lead-in wire, the support parallel with arc-tube, ceramic jacket on the support and molybdenum foil, it is characterized in that: described PAR lamp also increases the flat cell-shell of a strap clamp and two molybdenum foils and two outer leads, described arc-tube, the arc-tube lead-in wire, support, earthenware and molybdenum foil wrap up by cell-shell, by the flat sealing-in of the folder of cell-shell, be connected with two molybdenum foils of folder in flat below the cell-shell respectively at the lead-in wire of arc-tube lower end and support, two molybdenum foils connect two outer leads again respectively and constitute the metal halide bulb, bulb is fixed by the through hole that two outer leads pass the lamp holder end of Lamp cup, and two outer leads are connected with two positions of mutually insulated on the lamp holder respectively.Because arc-tube is sealed in the cell-shell, improving its sealing property, only need vacuumize or fill inert gas in cell-shell and get final product, therefore, the utility model has the situation of damage, cracking, gas leakage in Lamp cup or bowl cover or both joint portions, metal halide lamp still can operate as normal, this has just improved PAR lamp useful life, can also simplify the mounting process of arc-tube simultaneously, thereby under the situation that improves the PAR lamp behaviour, cost not only not to be increased, but also has reduced.
The utility model can be done following improvement: owing to need not the filling inert gas in the Lamp cup or vacuumizing, only need simple bonding getting final product between described Lamp cup and the bowl cover, need not to adopt special equipment to carry out the fire envelope, thereby can reduce the processing cost that is connected of Lamp cup and bowl cover greatly and simplify technological process.
The utility model solves its technical problem can also adopt following technical scheme: a kind of PAR lamp of metal halide lamp as light source, comprise lamp holder, the Lamp cup of inner surface belt reflectance coating, bowl cover, arc-tube, the arc-tube lead-in wire, ceramic jacket, it is characterized in that: described PAR lamp also increases a cell-shell, arc-tube is wrapped to form bulb by cell-shell, on the arc-tube, following two ends lead-in wire passes cell-shell from cell-shell, following two ends pass outside the cell-shell, wherein, the lead-in wire of arc-tube upper end is crooked parallel with arc-tube or substantially parallel downwards, article two, the arc-tube lead-in wire through hole that passes the lamp holder end of Lamp cup is fixed, and is connected with two positions of mutually insulated on the lamp holder respectively.
Technique scheme of the present utility model can also further be improved: the lead-in wire of described arc-tube upper end is being with the ceramic jacket that shields with the arc-tube adjacent, occurs because of the phenomenon that the PAR lamp that gasified rapidly by the arc-tube hyperthermia radiation to cause reduces useful life greatly to avoid described lead-in wire.
But cell-shell adopting quartz glass described in the utility model or similar material are made, and Lamp cup adopts adhesive means to be connected with bowl cover.
The beneficial effects of the utility model are:
(1) the utility model with arc-tube in addition comprise lead-in wire and support etc. all sealing-in in cell-shell, only in cell-shell, vacuumize or fill inert gas and get final product, and can adopt conventional cell-shell process for sealing to produce the metal halide bulb, sealing-in is effective, mechanization production degree height is promptly carried out the sealing-in of cell-shell before assembling; Therefore not only can improve the sealing of PAR lamp, can also avoid operate as normal because of PAR lamp Lamp cup cracking, gas leakage influence metallization halide lamp, thus the useful life of having improved the PAR lamp.
(2) since arc-tube in addition comprise lead-in wire and support etc. all sealing-in in cell-shell, can therefore need not to adopt expensive special equipment so that Lamp cup no longer needs to carry out fire envelope, only need Lamp cup and direct bonding the getting final product of bowl cover.Arc lamp first sealing-in before assembling and then adds a cover splicing in the Lamp cup of packing in cell-shell, simplified the production technology that metal halide lamp is made the PAR lamp of light source greatly, assembles more conveniently, not only improved production efficiency, but also reduced production cost.
(3) when metal halide lamp needs the filling inert gas, because the cell-shell volume much smaller than Lamp cup, so institute's gas consumption also obviously reduces, more can reduce production costs.
(4) since arc-tube many protection of one deck housing; therefore, can also have better explosion-proof performance, make the PAR lamp security performance of metal halide lamp as light source better; can be used for variously not only having required high illumination, but also having required the high place of security performance, throw light on as commodity displaying.
