Description

The inventive utility model relates to lighting technology and can find application in automotive lighting equipment, namely, in headlights for vehicles that provide safe and comfortable driving.

A vehicle lighting device is known, patent RU 2220364 C1, published December 27, 2003, comprising a housing, a diffuser connected to the housing and having various light zones and / or optical properties, a printed circuit board and light sources with lamp holders installed in the reflectors.

The disadvantages of this device are:

- complexity of execution,

- insufficient lighting parameters.

The closest analogue to the claimed utility model in terms of essential features is a headlight with an LED radiation source for a car, described in an article by K. Aichorn “Trends in the development of car light systems”, Svetotekhnika magazine, No. 3, 2005, p. 34,

comprising a power source, a control unit, and LEDs as a light source.

The disadvantages of the closest analogue are:

- Separate execution of far, dipped lighting and side light;

- increased headlight sizes;

- design complexity;

- unreliability in operation.

The task to which the proposed utility model is directed is to create a headlight that combines the near, far and dimensional illumination of a car.

The technical result of this utility model is to expand the functionality, reliability and efficiency of the headlamp.

The claimed technical result is achieved in that in a headlamp with an LED radiation source containing a power source, a control unit, LEDs

- LEDs are installed on the boards

- in the center of the headlight there is a marker light LED,

- the remaining LEDs are located evenly relative to the center of the headlight,

- LEDs located evenly relative to the center of the headlight are equipped with secondary optics,

- part of the secondary optics has a narrow angle of divergence of the high beam, and another part has a wide angle of divergence of the low beam,

- the boards are triangular,

- boards are installed with their peaks to the center of the headlight,

- LEDs are placed at the corners of the triangular boards,

- boards are made with a metal base,

- boards with LEDs and secondary optics with a narrow angle of divergence of the main beam, located alternately, through one board, with boards on which the LEDs and secondary optics with a wide angle of divergence of the passing beam are located.

In a headlamp with an LED radiation source, a new set of structural elements, as well as the presence of connections between them, make it possible to abandon the separate design of the near distant and marker lights of the headlamp, in addition, the life of the headlamp on LEDs has been significantly increased.

The essence of the proposed technical solution is illustrated by the drawing, which shows a General view of the headlamp device with an LED radiation source.

A headlamp with an LED radiation source contains a control unit 1, a power source 2, LEDs 3, 4, 5. LED 5 is mounted on a circuit board (not shown) and is located in the center of the headlamp. At the corners of the triangular boards 6, LEDs 3, 4 are placed. The boards 6 are mounted uniformly with respect to the center of the headlight, with their vertices towards the center of the headlight. Each LED 3 on the triangular boards 6 is equipped with secondary optics with a wide beam divergence angle. Each LED 4 on the triangular boards 6 is equipped with secondary optics with a narrow beam divergence angle. Boards 6 are made two-layer, with an upper textolite board on which all the connections are made, and a lower one with a metal plate, to ensure heat dissipation from the LEDs and to prevent their overheating (not shown).

It is possible to evenly arrange the LEDs relative to the center of the headlight on rectangular boards with LEDs installed in the corners (not shown).

The device operates as follows.

In the dipped beam mode, the control unit 1, through the power supply 2, includes only boards 6 with LEDs 3 equipped with secondary optics with a wide beam scattering angle.

In the high beam mode, the control unit 1 through the power source 2 includes, as a board 6 with LEDs 3, equipped

secondary optics with a wide scattering angle, and boards with LEDs 4 equipped with secondary optics with a narrow beam scattering angle. In the side light mode, the control unit 1 through the power source 2 turns on only a single LED 5.

The layout solution allows you to combine on the headlight near, far and dimensional lighting of the car.

An example of a specific implementation.

Currently, a prototype has been manufactured, which has passed stationary tests.
