Description

High voltage withstanding impact long-life halogen lamp

Technical field

The utility model belongs to motorcycle light source part technical field, and in particular to a kind of high voltage withstanding impact long-life halogen Plain lamp.

Background technology

As is known in the industry, the stability of motorcycle electric power system voltage is relatively poor, when voltage exceedes certain value（It is specified Value）When, bulb will burn.In general, light efficiency is higher, and the impact resistance voltage of bulb is higher.It is photochromic inclined but light efficiency is too low Huang, while differ and surely meet the requirement of luminous flux.And then as is known in the industry, halogen gas is filled with the glass bulb of Halogen lamp LED Body, and because the atomic molar ratio nitrogen of krypton is much bigger, therefore it is believed that it is to have helped to the life-span for improving bulb to be not added with nitrogen Help, be not generally filled with nitrogen in Halogen lamp LED accordingly.

In common incandescent type filament bulb, because the blowing pressure is less than an atmospheric pressure, thus filled in glass bulb A certain amount of nitrogen is usual way to the life-span for suppressing to jump electricity and use raising bulb.Such as United States Patent (USP) US2012/0007518 " Halogen lamp LED under the conditions of pulsed operation " recommended is referred to the nitrogen that 0.1-5%mol is filled in glass bulb.

The test for the non-finite number of time made through the applicant shows：If the nitrogen loading in glass bulb is too low, then DeGrain for improving proof voltage impact, if nitrogen loading is too high, then shadow on the one hand is produced to bulb life Ring（GB/T15766.2, life test voltage is 13.2V under laboratory test condition）, on the other hand to proof voltage impact capacity Help not only unobvious have on the contrary decline be inclined to, this may with nitrogen to suppress tungsten evaporability it is more relevant than Krypton difference.In addition The life test made by laboratory to bulb is built upon what is carried out under the conditions of stable direct current supply, thus can not be accurate React the life-span under the conditions of actual power.

In summary, the technology for how improving the high voltage withstanding impact capacity of the Halogen lamp LED as motorcycle light source part is asked Topic suffers from industry and it is expected to have breakthrough for a long time, and technical scheme described below is to produce under this background Raw.
