Definitions
- the invention transform the glare into beam light and increase the efficiency of it.
- the normal capped vehicle xenon metal halide lamps need a very complex and expensive accessory to fix the raw lamp at the right position on cap stably.
- the invention gives a much simple way to fix the raw lamp on cap with much lower cost.
- the capped xenon metal halide discharge lamp for vehicles includes an arc tube (1) with two neck shaped portions (2a, 2b). These two neck shaped portions are gastight sealed for two electrode connectors (4a, 4b).
- the arc tube and two neck shaped portions are wrapped by an outer gastight tubular envelope (5) but with a ball shaped portion (5a), which just surround the ball shaped arc tube (1) .
- the first end of envelope is fixed on a cap (15).
- a nickel wire (7) is through bridge (8) or directly connected to current conduct (4b) of the second electrode (3b). Wire (7) runs along out side of lamp to connect the second current supply conductor (14).
- second neck shape portion of arc tube (2c) is expanded to bell shaped, the edge of the bell (2c) nearly touches with the outer envelope (5) and then gastight seal both by flame.
- a cylinder shaped sink (16) at the surface center of cap (15) and three or more (such as four) stainless steal poles (11) are implanted on the cap surface surrounded the sink (16).
- the first end of lamp is inserted in the sink (16), there is a ring shaped hoop (10) constructed by one or two or four sections, which is tightly bind round the lower part of outer envelope (5).
- Four poles (11) are inserted in four holes (10a 10b) on the wings of ring shaped hoop (10) respectively and melt together by point welding.
- the outer envelope (5) of arc tube (1) is not real straight tubular shaped but with a ball shaped portion (5a) just surround the ball shaped arc tube (1). But the arc tube of nonnal xenon metal halide lamp for vehicle is surrounded by straight tubular envelope. This invention is very helpful to reduce the glare from arc tube and increase the lighting efficiency, it is very clear from following description.
- the refracted light beam will be divided to two parts at the interface II of glass and air, the first part will go out through glass plate and become transmission light, another part of refracted beam will be reflected again by second interface II, then go back to first interface I, then a part of this reflected light go out and become transmission light , another part of it will be reflected again by first interface I. Obviously a part of reflect light will continue to reflect between two interface I and II time after times, every time a part of reflected beam light go out through interface and become transmission light.
- the main points of this invention are:
- Embodiments of invention xenon metal halide lamp for vehicles are shown in the drawing, in which
