The utility model provides a single filament halogen tungsten lamp for vehicle low beam illumination. The lamp comprises a glass outer cover, the lamp is filled with a halide and an inert gas, the top is coated with a black light-shielding coating, and a filament is arranged in the bubble, which is consistent with the position of the low-beam filament of the existing H4 lamp, that is, the filament is lighted. Positioning (the lamp is placed horizontally horizontally when lighting), the filament lead is connected to the wire passing through the lamp cap, the filament is arranged in the direction coaxial with the bulb, and the distance between the bottom of the filament and the base of the lamp head is 28.5 to 28.8 mm, The utility model is characterized in that: a small hood is arranged on the near side of the lower part of the filament, and the upper end of the filament is welded on the top of the hood, the hood is fixed by a common nickel rod spot welding, and the bottom of the lamp is sealed by a pinch seal. The single filament halogen tungsten lamp of the utility model can be installed in the H4 type lamp to obtain the near-light shape conforming to the standard, and can be separately installed in the vehicle to generate low beam illumination, or can be combined with the xenon metal halide lamp to form and have Combination light for far and near light function.
