Description

Color-changeable LED headlamp of motor vehicle

Technical Field

The utility model relates to a motor vehicle lighting system, in particular to a variable-color LED headlamp of a motor vehicle.

Background

With the development of semiconductor technology, the cost of LED light sources is reduced year by year, and LEDs are more and more widely applied as light sources of automobile lamps. The ultra-long service life and the excellent optical performance of the fluorescent lamp are favored by all users, and halogen headlights and xenon headlights are completely eliminated in the future. The existing LED headlamp can enable drivers and passengers to obtain more excellent visual fields in ordinary weather because the light color of the LED headlamp is closer to natural light. However, the LED headlamp has the defects that when the LED headlamp is used in foggy days, the vision of drivers and passengers is not far enough due to insufficient white light penetrability, so that the driving safety is influenced; to overcome this drawback, the host plant usually employs the following two schemes to circumvent:

the first scheme is as follows: the halogen headlamp is adopted to emit partial yellow light with stronger penetrability, so that the problem of the lamplight performance in foggy days can be solved. When the halogen headlamp is used in ordinary weather, the emitted yellow light makes drivers and passengers feel dim subjectively, and the service life of the halogen light source is not long; therefore, the current halogen headlamps are eliminated in middle and high-end vehicle models; and will be completely eliminated in future.

Scheme II: a front fog lamp is added to be used as supplementary light in foggy days. But as the fog light range is much smaller than the high/low beam, it only serves as a tonic rather than an optimal solution.

Both of the above conventional solutions have their own disadvantages and require an additional solution for searching for a ball.

"a double-colored temperature LED head-light" that CN 208919981U discloses, including lamp plate component and power, the last a plurality of lamp stands that are provided with of lamp plate component, install the light source of two kinds of high colour temperature LED light source and low colour temperature LED light source in a plurality of lamp stands, every the lamp stand cover has a reflector, and is a plurality of the reflector is kept away from lamp plate component's one end covers has the printing opacity mirror, the lamp stand of high colour temperature LED light source and low colour temperature LED light source is connected in the power through the switch respectively. The LED lamp is illuminated by using a high-color-temperature LED light source under the conventional condition, and can meet the index requirement that the central light intensity is more than or equal to 2000000cd during normal illumination; open low colour temperature LED light source auxiliary lighting when rain and fog weather, effectively increase the yellow light composition in the light, the penetrability of reinforcing light has solved the short problem of rain and fog weather illumination distance. The technical solution disclosed in this patent document is a useful attempt in the field of the technology.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a variable-color LED headlamp, which can provide optimal comfortable vision for drivers and customers all the day, can emit far/near common white light in normal weather, and can convert and emit yellow light (light color close to a halogen light source) with stronger penetrability in rainy and foggy weather.

The utility model relates to a color-changeable LED headlamp, which comprises a big lamp control module and a fog lamp switch electrically connected with the big lamp control module, and is characterized in that: a plurality of white light LED light sources are arranged on a module PCB of the big lamp control module, and a yellow light LED light source is arranged on one side of each white light LED light source.

Further, the fog light switch is integrated in a lamp combination switch of a vehicle, which is installed on the left side of a steering wheel.

Furthermore, the module PCB is provided with six white light LED light sources and six yellow light LED light sources.

The utility model has the beneficial effects that:

because the module PCB board of the headlamp control module is provided with the plurality of white light LED light sources, and one side of each white light LED light source is provided with the yellow light LED light source, the optimal comfortable visual field can be provided for drivers and passengers and customers all the time; in normal weather, far/near normal white light is emitted, and in rain and fog weather, yellow light with stronger penetrability (light color close to a halogen light source) can be converted and emitted. The white light is changed into yellow light with stronger penetrability, and the using requirements of two different weathers, namely normal weather and foggy weather, can be met simultaneously.

FIG. 2 is a schematic view of a white LED light source and a yellow LED light source disposed on a module PCB board;

fig. 3 is a schematic diagram of a lamp combination switch.

In the figure: the LED lamp comprises a fog lamp switch 1, a large lamp control module 2, a module PCB 3, a white light LED light source 4, a yellow light LED light source 5 and a lamp combination switch 6.

Detailed Description

The utility model is further described with reference to the accompanying drawings in which:

referring to fig. 1, 2 and 3, the color-changeable LED headlamp comprises a large lamp control module 2 and a fog lamp switch 1 electrically connected thereto, and is characterized in that: a plurality of white light LED light sources 4 are arranged on a module PCB 3 of the headlamp control module 2, and a yellow light LED light source 5 is arranged on one side of each white light LED light source 4.

The fog light switch 1 is integrated in a lamp combination switch 6 of the vehicle, the lamp combination switch 6 being mounted on the left side of the steering wheel.

Six white light LED light sources 4 and six yellow light LED light sources 5 are arranged on the module PCB 3.

The color-variable LED headlamp comprises a left headlamp and a right headlamp which are symmetrically arranged in an abstract way; only the left headlamp is explained above.

The shapes of all parts in the left headlamp and the right headlamp can be adjusted according to actual needs, and are not required to be completely consistent with example pictures.

When the driver and passengers find that the front road is fogged, the fog lamp function is started through the combination switch 6, and the command can be transmitted to the big lamp control module 21 through LIN signals or other signals; after receiving and converting the command, the headlight control module 21 drives and lights the yellow LED light source 5 integrated on the headlight module PCB 3. So that the light obtained by the driver is the matched color of the white LED light source 4 and the yellow LED light source 5. Compared with a white light headlamp, the light has better penetrability, and safer light is provided for users in foggy days.
