Description

High beam headlamp illumination system

Technical Field

The utility model belongs to lamps and lanterns field among the vehicle particularly, the utility model relates to a high beam lighting system for head-light.

Background

Headlamps, also called headlamps, are mounted on both sides of the head of a vehicle, such as an automobile, for night lighting. Since the lighting effect of the headlamps directly affects the operation and traffic safety of night driving, the traffic control departments in all countries of the world often stipulate the lighting standards in the form of laws. With the continuous development of the technology, the incandescent vacuum lamp is eliminated successively in the past, and the existing automobile headlamp mainly adopts a halogen lamp and a xenon lamp.

Vehicle headlamps, such as automobile headlamps, have unique light distribution structures, and may be classified into high beams and low beams according to the type of light emitted. For example, the light emitted from the high beam is reflected by the reflector and then directly emitted forward to form the "high beam". The light emitted by the low-beam light is blocked to the upper half part of the lampshade reflector by the shading plate, and the reflected light rays are downwards diffused to the ground to form low-beam light, so that dazzling of drivers on opposite vehicles is avoided.

As shown in fig. 1 and fig. 2, the ECE R112 high beam test points and the light intensity requirements, for example, the test points are HV center point min 40500cd, left and right 2.5 degree point min 20300cd, left and right 5 degree point min 5100cd, and the maximum value in the area is not more than 21 kilo cd. Fig. 3 shows the requirement of a high beam lamp of American standard, the requirement of a left test point and a right test point is more and wider, the left test point and the right test point reach 12L/12R, meanwhile, the maximum value in the area is only 75000cd, which is nearly 3 times lower than 21 ten thousand cd of ECE R112, and the glare of an opposite vehicle is not easy to cause. Meanwhile, the ground faces downwards for 4 degrees, namely max 5000cd, so that the driving is prevented from being influenced by the over-brightness of the ground in the near field.

Fig. 4 is a schematic diagram of a high beam lamp of a gas discharge lamp commonly used in the market, in which 12 is a gas discharge lamp, the gas discharge lamp 12 is inserted through an opening at the bottom of the rotational ellipsoid 11, so that the illuminant F1 of the gas discharge lamp 12 coincides with the focal point of the rotational ellipsoid 11, most of the light of the gas discharge lamp 12 is reflected to the virtual focal point F2 through the rotational ellipsoid 11, and then is projected by the condenser lens 13 to form the high beam lamp. As can be seen from fig. 4, part of the light of the gas discharge lamp 12 is wasted without being reflected and collected by the ellipsoid of revolution 11, and the power of the gas discharge lamp 12 is large, and heat cannot be conducted out quickly, and is mainly dispersed in the lamp body in the form of light heat, thereby resulting in high temperature and short lifetime of the light-emitting body.

As a novel light source, the LED has many advantages which other lighting sources do not have, such as low voltage, long service life, small volume, light weight, fast response, no radiation, no pollution and various severe conditions resistance, and the LED has the advantages that the light emitting direction is one-sided (the traditional light source is 360 degrees of the volume), the collection and utilization of light rays are facilitated, the light utilization rate is improved, and the like. Therefore, it is a new trend to manufacture LED headlamps with LEDs as light sources, but the existing LEDs have low luminous flux, and must increase current to increase luminous flux, resulting in large heat generation, large heat dissipation volume, and reduced lifetime.

In addition, the LED high beam in the market is used, the main optical system is shown in fig. 5, 21 is a semi-elliptical rotating body, 22 is an LED module, the light emitting direction of 22LED module is perpendicular to the vehicle driving direction, the light emitted by 22LED module coincides with the focus F1 of 21 semi-elliptical rotating body, the light emitted by 22LED module is reflected to the focus area F2 by 21 semi-elliptical rotating body, and then forms the high beam through the projection effect of the condenser lens 23. Since the 22LED module is perpendicular to the driving direction, it is not favorable for the structural design of the high beam single body required by IP67, which results in a more complicated structure and is also unfavorable for the design of the heat dissipation structure.
