Description

Headlight assembly with high and low beam lights

The present invention relates to a vehicle lamp assembly, and more particularly to a vehicle lamp capable of producing both high beam and low beam effects.

Please refer to the invention patent case of high and low beam lens car lamp of Taiwan, No. TW I776531. The high and low beam lens car lamp of the case includes a lamp holder, a front light source, a horizontal mask, a rear light source and a lamp cover, wherein: the lamp holder is formed by a first lamp cover and a second lamp cover respectively located at the upper and lower parts, and a reflective reflector cup and a projective reflector cup are arranged at the front and rear positions above the first lamp cover, and the reflective reflector cup and the projective reflector cup are connected by a V-shaped joint part, and the joint part has a reflective surface connected to the rear end of the reflective reflector cup. The front light source is installed in the second lamp cover below the reflective reflector cup, so that the first light irradiated from the front light source to the rear and upper parts directly passes through the reflective surface and the reflective reflector cup, and then passes through the front of the heat dissipation lamp holder. The high-beam light transmissive portion above the lamp cover at the end thereof is emitted to form a high-beam light with a longer irradiation distance, and a projection channel is formed at the front of the interior of the second lamp cover. When the front light source, the horizontal shield and the rear light source are sequentially installed inside the second lamp cover from front to back, the carrier plate and the horizontal shield used to provide the front light source for carrying can just cover the top of the projection channel. Through the formation of the first notch at the rear end of the carrier plate and the second notch at the front end of the horizontal shield, the second light irradiated upward by the rear light source can be reflected by the projection-type reflective cup, and is forcibly sent into the projection channel from between the first notch and the second notch, and then is sent forward to be emitted from the low-beam light transmissive portion below the lamp cover, and through the diffusion effect generated by the low-beam light transmissive portion, a low-beam light with a shorter irradiation distance is formed.

However, the actual implementation of the headlight has the following shortcomings:

1. Since the reflective reflector cup and the projective reflector cup are located at the front and rear positions of the first lampshade, and the reflective reflector cup and the projective reflector cup are connected by a V-shaped joint, the overall length of the headlight is too long, which is not conducive to the headlight shape design.

2. The front light source is mounted on a carrier board, which is then assembled and fixed on the second lampshade at its two sides. This structural design will make it difficult for the heat energy generated by the front light source to dissipate through the second lampshade, thus affecting the service life of the front light source.

The inventor of the present invention has developed the vehicle lamp of the present invention in view of the defects in the actual implementation and use of the above-mentioned high and low beam lens vehicle lamp invention patent case No. TW I776531.

The purpose of the present invention is to provide a headlight assembly with high and low beams. The headlight assembly can improve the defect of the headlight being too long and difficult to design by arranging the positions of the high and low beam light sources. The high and low beam light sources are both installed on a heat sink holder with heat sink fins, which has a good heat dissipation effect and can extend the service life of the high and low beam light sources.

The above-mentioned purpose of the present invention is achieved by the following technologies:

A vehicle lamp assembly with high and low beam lights, the vehicle lamp comprises a heat dissipation lamp holder, a high beam light source, a high beam reflector, a low beam light source, a low beam reflector, an arc-shaped light shield and a lens; wherein:

The heat sink lamp holder is an integrally arranged seat body with a hollow interior, and a plurality of heat sink fins are arranged on its outer peripheral surface. A high beam assembly section is integrally arranged on the upper edge of the front end of the heat sink lamp holder, and a low beam assembly section is arranged in the hollow interior extending from the rear end of the heat sink lamp holder toward the opening direction;

The high beam light source and the high beam reflector are mounted on the high beam assembly section, and the high beam reflector is arranged below the high beam light source, so that the optical axis of the high beam light source faces downward, and the first light emitted by the high beam light source is directed toward the high beam reflector;

The low beam light source and the low beam reflector are mounted on the low beam assembly section, and the low beam reflector is arranged above the low beam light source so that the optical axis of the low beam light source faces upward and the second light emitted by the low beam light source is directed toward the low beam reflector;

The arc-shaped light shield is located in front of the low beam light source and below the high beam reflector. The concave arc surface of the arc-shaped light shield faces the front end to form a concave area in front of the arc-shaped light shield. A channel is defined between the arc-shaped light shield and the high beam reflector, and the channel is for the second light reflected from the low beam reflector to pass through.

The upper section of the lens is a high beam lens area, and the lower section is a low beam lens area; the first light is reflected by the high beam reflector and then emitted from the high beam lens area to form a high beam; the second light is reflected by the low beam reflector and then emitted from the low beam lens area through the channel to form a low beam.

The vehicle lamp assembly with high and low beam lights as described above, wherein the vehicle lamp further comprises a fixing frame, wherein the fixing frame is an annular frame body with two ends penetrating and connected, the fixing frame is combined with the front end of the heat dissipation lamp holder, and the lens is fixed in the fixing frame and protrudes forward from the fixing frame.

In the vehicle light assembly with high and low beam lights as described above, the two ends of the arc-shaped sunshade extend toward the rear end of the heat sink lamp holder to form a foot column, and the foot column is connected to a locking plate, and a locking piece passes through the locking plate and locks to the front side of the low beam reflector cover, so that the arc-shaped sunshade is assembled on the front side of the low beam reflector cover.

The advantages of the present invention are:

1. Through the positional arrangement of the high beam light source, the high beam reflector, the low beam light source, the low beam reflector, and the arc-shaped light shield, the length of the headlight formed by the present invention can be effectively reduced compared to the headlight disclosed in TW I776531, making the headlight of the present invention more universal and applicable when installed on a vehicle.

2. Because the high beam light source and the low beam light source are directly mounted on the high beam assembly section and the low beam assembly section of the lamp holder respectively, and the lamp holder is a shell with a good heat dissipation coefficient and a heat dissipation fin, it can quickly absorb the heat generated by the high beam light source and the low beam light source, and dissipate the heat, thereby extending the service life of the high beam light source and the low beam light source.

In order to make the technical content, purpose of the invention and the effects achieved by the present invention more complete and clear, they are described in detail below, and please refer to the disclosed drawings and figure numbers:

Please refer to Figures 1 to 3.

The vehicle lamp of the present invention can emit high beam and low beam effects; it comprises a heat dissipation lamp holder 1, a high beam light source 2, a high beam reflector 3, a low beam light source 4, a low beam reflector 5, an arc-shaped light shield 6 and a lens 7; wherein:

The heat sink lamp holder 1 is an integrally arranged seat body with a hollow interior. A plurality of integrally arranged heat sink fins 11 are arranged on the outer peripheral surface of the heat sink lamp holder 1. A high beam assembly section 12 is integrally arranged on the upper edge of the front end of the heat sink lamp holder 1. A low beam assembly section 13 is integrally arranged in the hollow interior of the heat sink lamp holder 1 and extends from the rear end of the heat sink lamp holder 1 toward the opening of the hollow interior.

The high beam light source 2 and the high beam reflector 3 are mounted on the high beam assembly section 12, and the high beam reflector 3 is located below the high beam light source 2, so that the optical axis of the high beam light source 2 is directed downward, so that the first light emitted by the high beam light source 2 will be directed toward the high beam reflector 3;

The low beam light source 4 and the low beam reflector 5 are mounted on the low beam assembly section 13. The low beam reflector 5 is disposed above the low beam light source 4, and the optical axis of the low beam light source 4 is directed upward, so that the second light emitted by the low beam light source 4 is directed toward the low beam reflector 5.

The arc-shaped light shield 6 is located at the front side of the low beam light source 4 and below the high beam reflector 3. The front surface of the arc-shaped light shield 6 forms a concave arc surface 61, so that the front side of the arc-shaped light shield 6 toward the front end forms a concave area 62, and a channel A is defined between the arc-shaped light shield 6 and the high beam reflector 3, and the channel A is for the second light reflected from the low beam reflector 5 to pass through; preferably, the arc-shaped light shield 6 is provided with legs 63 extending toward the rear end of the heat sink lamp holder 1 on both sides, and the legs 63 are connected with a locking piece 64, so that a locking piece 65 passes through the locking piece 64 and is locked to the front side of the low beam reflector 5, so that the arc-shaped light shield 6 is assembled on the front side of the low beam reflector 5;

The lens 7 is integrally arranged, the upper section of which is a high beam lens area 71, and the lower section is a low beam lens area 72; the first light emitted by the high beam light source 2 is reflected by the high beam reflector 3 and then emitted from the high beam lens area 71 of the lens 7 to form a high beam; and the second light emitted by the low beam light source 4 is reflected by the low beam reflector 5 and then emitted from the low beam lens area 72 through the channel A to form a low beam.

In a preferred embodiment of the present invention, the vehicle lamp of the present invention further comprises a fixing frame 8, which is an annular frame with two ends penetrating and connected, and is combined with the front end of the heat sink lamp holder 1, and the lens 7 is fixed in the fixing frame 8 and protrudes forward from the fixing frame 8.

In this way (please refer to the fourth figure below), when the user switches to light up the high beam light source 2, the first light emitted by the high beam light source 2 will directly hit the high beam reflector 3, and after being reflected by the high beam reflector 3, it will be emitted from the high beam lens area 71 of the lens 7 to form a high beam effect; and when the user switches to light up the low beam light source 4, the second light emitted by the low beam light source 4 will hit the low beam reflector 5, and after being reflected by the low beam reflector 5, the second light will pass through the channel A and then be emitted from the low beam lens area 72 of the lens 7 to form a low beam effect.

Since the high beam light source 2 and the low beam light source 4 of the vehicle lamp of the present invention are directly mounted on the high beam assembly section 12 and the low beam assembly section 13 which are integrally provided with the heat sink holder 1, the heat sink holder 1 can directly absorb the heat source generated by the high beam light source 2 and the low beam light source 4 during the operation of the light emission, and quickly discharge the absorbed heat source through the heat sink fins 11 on the heat sink holder 1. In addition, the high temperature state of the high beam light source 2 and the low beam light source 4 can be quickly dissipated, thereby extending the service life of the high beam light source 2 and the low beam light source 4; in addition, through the position arrangement of the high beam light source 2, the high beam reflector 3 and the low beam light source 4, the low beam reflector 5, and the arc-shaped sunshade 6, the length of the vehicle lamp composed of the present invention is effectively shortened compared with the vehicle lamp disclosed in TW I776531, making the vehicle lamp of the present invention more universal and applicable when installed on a vehicle.
