Description

With the hard glass Halogen lamp LED of molybdenum foil sealing-in

Technical field

The utility model belongs to automotive luminaire component technology field, and in particular to a kind of and hard glass halogen of molybdenum foil sealing-in Plain lamp.

Background technology

As is known in the industry, the glass that Halogen lamp LED uses has two major classes：First, using German SCHOTT companies as the hard of representative Glass, it is contemplated that coefficient of expansion problem, thus use molybdenum rod sealing-in therewith；Second, the quartz glass that China is domestic, due to quartz The coefficient of expansion of glass is minimum（5.5×10^-7/℃）, thus almost can be matching without a kind of metal.It it is 30 μm by thickness It is current widespread practice that the edge of molybdenum foil, which is electrolyzed to produce after cutting edge shape with quartz glass sealing-in, to this referring also to " lamp molybdenum Paper tinsel technical requirements "（Chinese electric lighting, 2017-1）.And then as is known in the industry, when drawing, surface easily shaft-like molybdenum rod occurs Crackle, the crackle can influence the sealing-in sealing with glass, so as to cause bulb gas leakage.

Because foregoing hard glass and quartz glass is each has something to recommend him, thus it is no lack of factory interested in hard glass bulb bulb Business, equally also it is no lack of the manufacturer that great interest is produced to quartz crust bulb.But if select hard using the manufacturer of bulb Glass bulb bulb, then the production firm of quartz crust bulb can not meet the requirement for providing a user hard glass bulb, and this is Because molybdenum foil is easily deformed.It follows that the manufacture difficulty of quartz glass bulb is higher than hard glass bulb.

Then, if directly produced on the premise of without being electrolyzed to produce cutting edge shape to the edge of molybdenum foil in quartz lamp By molybdenum foil and hard glass sealing-in on line, then a good technical measures of can yet be regarded as, but disclosed special so far Profit and non-patent literature in be showed no it is all have corresponding technical inspiration, technical scheme described below is in this background Caused by lower.

The content of the invention

Task of the present utility model is to provide a kind of without the edge of molybdenum foil is electrolyzed to produce into cutting edge shape and can directly be existed On quartz lamp production line with hard glass sealing-in and use the sealing for reducing manufacture difficulty, being advantageous to ensure molybdenum foil and hard glass Sealing-in effect and use the hard glass Halogen lamp LED with molybdenum foil sealing-in that is avoiding gas leakage.

What task of the present utility model was performed by, a kind of and hard glass Halogen lamp LED of molybdenum foil sealing-in, including hair Body is steeped, hair bubble body includes a hard glass bulb, a glass bulb chamber blind end is extended with the lower end of hard glass bulb, and hard The hard glass bulb intracavitary of matter glass bulb is provided with filament, and the filament is serially connected between the upper end of a pair of first molybdenum rods, and this is to the first molybdenum The lower end of bar extends towards the direction of glass bulb chamber blind end, and has a pair of molybdenum foils in the glass bulb chamber blind end inner sealing, described Top of the lower end respectively with a pair of molybdenum foils of a pair of first molybdenum rods be electrically connected, and the bottom of a pair of molybdenum foils respectively with a pair the The upper end electrical connection of two molybdenum rods, the lower end to the second molybdenum rod extend to outside glass bulb chamber blind end and in a state of use with Lamp holder be electrically connected, wherein, described glass bulb chamber blind end by it is being mutually symmetrical and respectively in flat two glass bulbs close valve Be combined as a whole composition, and a pair of described molybdenum foils are characterised by a pair of described molybdenums between described two glass closing valve The thickness of paper tinsel is 50-100 μm.

In a specific embodiment of the present utility model, it is provided with a pair in the hard glass bulb intracavitary of the hard glass bulb Quartz pushrod, a pair described of first molybdenum rods are seized on both sides by the arms between a pair of quartz pushrods.

Technical scheme provided by the utility model due to by scope of the thickness selection of a pair of molybdenum foils at 50-100 μm, thus Without the edge of molybdenum foil is electrolyzed to produce into cutting edge shape and be able to can both be dropped directly on quartz lamp production line with hard glass sealing-in Low manufacture difficulty, and can ensure the seal effect of molybdenum foil and hard glass, avoid gas leakage.
