The present invention relates to a vehicle lamp, in particular to a vehicle LED lamp with a remote lamp and a near lamp function, which is small in size, light in weight, and capable of allowing a near-light assembly to project a concentrated light curtain to avoid general urban traffic or Improper traffic can cause traffic accidents that hinder the direction of the car or the driving force of the car.

The existing automobile headlights respectively have an independent low-light module and an independent high-light module to provide the function of the near lamp and the remote lamp respectively, and the near lamp can be used for the occasion of the street lamp illumination in the urban area, and the far lamp provides The car is used in the absence of lighting in the suburbs, on the mountain, or in places where the fog or air pollution is severe and the visibility is low. However, since the headlights are respectively equipped with the near-light module and the high-light module, the circuit design and assembly are obvious. The complexity of the headlights increases the cost of the headlights and the maintenance is not easy.

In addition, the long-light module and the near-light module of the existing automobile headlight adopt a tungsten filament bulb, which has low efficiency and has a problem that the tungsten wire is blown or the glass cover is broken and damaged, so the life and the application are not good.

Although light-emitting diodes have been proposed as the main lighting component of the headlights, the light curtains illuminated by the near-light modules cannot be concentrated so that the forward or opposite vehicles are exposed to light, posing a hazard.

In view of the shortcomings of the current car headlights and the near-light module light curtains, the creators have improved their shortcomings and lacks, and then created a vehicle LED lamp with a long-light and near-light function.

The main purpose of this creation is to provide a vehicle LED lamp with a long lamp and a near lamp function, which is small in size and light in weight, and can allow the near lamp assembly to project a concentrated light curtain to avoid improper operation in the general urban area or when the car is in use. A traffic accident is caused by obstructing the direction of sight or the vision of a driving car.

In order to achieve the above purposes, the aforementioned automotive LED lamps with remote and near-light functions include:

a base having a fixing seat formed thereon, and two fixed surfaces of the opposite sides are formed on both sides of the fixing seat;

The two high-light components are respectively fixed on the two fixing surfaces of the fixed seat, and each of the high-light components has a high-light circuit board and at least one high-light emitting diode, and the high-light circuit board is disposed on the corresponding fixed surface. The high-beam light-emitting diode is disposed on the high-light circuit board;

By the above technical means, the vehicle LED lamp with the function of the far lamp and the near lamp can be installed in a large lamp cup of a car headlight, and when the vehicle lamp is used, the remote lamp component or the close lamp can be selectively turned on. When the high-light component is started, the light can be emitted in all directions and most of the emitted light is not restricted by the reflector. The emitted light is further reflected by the large lamp cup of the headlight and is emitted outside the headlight, and can be issued in parallel. The far-light light can achieve the high beam function, and the near-light assembly can be selectively turned on, so that the light below the horizontal level emitted by the near-light assembly is reflected upward by the reflector and is emitted upward to the top surface of the large-sized lamp cup, and then topped. The surface is reflected and directed downwards out of the lamp cup, so that most of the light can be projected in front of the headlights, so that the light can be concentrated to form a complete light curtain, thus achieving the low beam function. The reflector effectively controls the direction of travel of the light emitted by the near-light assembly, avoiding excessive light from exiting the headlights above the horizontal direction, and diffusing the low-beam light lines to affect the forward direction or the driving of the preceding vehicle. Sight.
