Description

car light bulb

technical field

The embodiment of the utility model relates to a light bulb of a vehicle light, especially a light bulb of a vehicle light using a solid-state light source.

Background technique

In many lighting applications, incandescent light bulbs are gradually being replaced by more energy-efficient solid-state light sources, especially semiconductor light-emitting diodes (LEDs). In addition to being more energy efficient, solid-state light sources also have a longer lifespan than incandescent light bulbs. In addition, the color temperature of the solid-state light source is also easier to adjust to above 4000K, so that the desired cool color light can be easily provided. The aforementioned advantages of solid-state light sources make them particularly attractive for automotive lighting applications. There have been more and more car lights using LED solid-state light source, which provides the advantages of high lumens, high technology and fashion sense.

However, the light emitted by automotive bulbs (especially headlight bulbs), including low beam and high beam, must be able to meet the required safety standards, which is not easy to achieve for bulbs using solid-state light sources. Strict safety standards for beams of automotive headlights include emission angle requirements for low beams and convergence requirements for high beams. Since the output characteristics of the solid-state light source are completely different from those of the filament of an incandescent bulb (the beam angle generated by the solid-state light source is only 180 degrees, while the beam angle generated by the filament of the incandescent bulb reaches 360 degrees), the above-mentioned adjustment of the beam is realized through the LED solid-state light source Safety standards are not easy. Moreover, the thermal management of LED solid-state light sources is also a problem that needs to be considered.

Therefore, it is desirable to provide a light bulb for automobile lights using a solid-state light source, which can provide beam distributions of high and low beams that meet safety standards, and can well solve the problem of heat management.

detailed description

Reference will now be made to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. The examples are provided by way of illustration of the present invention and are not intended as limitations of the present invention. For example, features illustrated or described as part of one embodiment may be used in another embodiment to yield still a further embodiment. The present invention is intended to embrace these and other modifications and variations that fall within the scope and spirit of the present invention.

Referring to Figs. 1-3, the light bulb of the vehicle lamp according to the present invention includes a main body 1, which can be, for example, a metal or alloy body, such as an aluminum alloy body. A mounting part 5 may be provided on the main body 1 for integrally mounting the bulb in, for example, a lamp socket on a car.

A carrier 2 extends from one side of the main body 1 and forms a first main plane 21 and a second main plane 22 opposite to each other. The carrier 2 has a small thickness between the first main plane 21 and the second main plane 22 , for example less than 3 mm, preferably less than 2.5 mm. A first solid-state light source 31 is installed on the first main plane 21 , and a second solid-state light source 32 is installed on the second main plane 22 . The first solid-state light source 31 and the second solid-state light source 32 are used as light sources for the low beam of the bulb. In this embodiment, the first solid-state light source 31 and the second solid-state light source 32 are respectively a plurality of light-emitting diodes (LEDs) arranged linearly along the extending direction of the carrier 2 . These light-emitting diodes can be installed on two printed circuit boards respectively, and these two printed circuit boards are respectively installed on the two sides on the carrier 2, thus, the surfaces of these two printed circuit boards respectively serve as the first main plane 21 and the second principal plane 22 .

A first reflector facing the first solid-state light source 31 is also provided on the first main plane 21 for reflecting light from the first solid-state light source 31; A second reflector for reflecting light from the second solid state light source 32 . In the embodiment shown in FIGS. 1-3, on one side of the first solid state light source 31 (shown as the underside of the first solid state light source 31 in FIGS. 2-3 ) there is a first The protrusion 41, the concave curved surface 411 of the first protrusion 41 provides the first reflector. On the same side of the second solid-state light source 32 as the first protrusion on the first solid-state light source 31 (i.e., the lower side of the second solid-state light source 32), there is a second protrusion 42 protruding from the second main plane 22, the second protrusion 42 protruding from the second main plane 22, The concave curved surface 421 of the two protrusions 42 provides the second reflector. Both the concave curved surfaces 411 and 421 are smooth enough to efficiently reflect light from the first solid-state light source 31 and the second solid-state light source 32 respectively.

In order to enable the bulb to emit substantially the same intensity of light on the left and right sides, the first solid-state light source 31 and the second solid-state light source 32 usually have the same configuration, that is, have the same number of LED units, have the same luminous power, and have the same size, and are respectively mounted on the first main plane 21 and the second main plane 22 at the same position and orientation.

As shown in FIG. 4, the light emitted by the first solid-state light source 31 is roughly reflected upwards by the concave curved surface 411 of the first protrusion 41 (as shown by the arrow) and reaches the reflective surface behind the lamp holder of the lamp on which the light bulb is installed, and then the The reflective surface at the rear of the car lamp socket then reflects the light to the front of the car; similarly, the light emitted by the second solid-state light source 32 is roughly reflected upwards by the concave curved surface 421 of the second protrusion 42 (as shown by the arrow) to reach The reflective surface behind the lamp holder of the light bulb is installed, and then the reflective surface behind the lamp holder reflects the light to the front of the car. In this way, the combined light emitted by the first solid-state light source 31 and the second solid-state light source 32 is reflected by the concave curved surfaces 411 and 421 and the reflective surface behind the lamp holder to form a low beam beam projected toward the front of the vehicle.

In order to make the luminous effect of the combination of the first solid-state light source 31 and the second solid-state light source 32 close to the almost 360-degree luminous range of a common halogen lamp, the distance d1 between the first main plane 21 and the second main plane 22 should be as small as possible, for example No more than 2.5mm, so that the first solid-state light source 31 and the second solid-state light source 32 are as close as possible.

In one embodiment, the length of the first reflector (that is, the concave curved surface 411) in the extending direction of the carrier 2 is preferably 1-1.5 times the length of the first solid-state light source 31 in the extending direction of the carrier 2, The length of the second reflector (ie the concave curved surface 421 ) in the extending direction of the carrier 2 is preferably 1-1.5 times the length of the second solid state light source 32 in the extending direction of the carrier 2 . Moreover, the first solid-state light source 31 is completely located within the extension length of the first reflector in the extension direction of the carrier 2, and one end of the first solid-state light source 31 close to the main body 1 is far from the first reflector close to the main body 1 The distance d2 of one end of the second solid-state light source 32 is completely located within the extension length of the second reflector in the extension direction of the carrier 2, and one end of the second solid-state light source 32 close to the main body 1 is at a distance from the second solid-state light source 32 The distance d2 of the end of the reflector close to the main body 1 does not exceed 1mm.

The concave curved surface 411 of the first protrusion and the concave curved surface 421 of the second protrusion are bowl-shaped three-dimensional curved surfaces. In one embodiment, the bottoms of the concave curved surfaces 411 and 421 are substantially flat, and the walls in three directions perpendicular to the bottom (except one side of the first main plane 21 or the second main plane 22 ) form Three-dimensional surfaces in space.

Referring to FIG. 5 , in one embodiment, as viewed from the position of the first solid-state light source 31 above the first protrusion 41 in a direction perpendicular to the first principal plane 21 , the top of the concave curved surface 411 of the first protrusion The distance d3 from the upper edge of the first solid state light source 31 is 0.4-0.6 mm, and the height d4 from the top to the bottom of the concave curved surface 411 of the first protrusion is about 1.5 times the height of the first solid state light source 31 .

Through the first reflector designed above, the light emitted by the first solid-state light source 31 and the second solid-state light source 32 can be reflected upward as much as possible to improve the light utilization rate of the light source.

Continuing to refer to FIG. 5, the second protrusion 42 is positioned on an imaginary plane (not shown) parallel to the first main plane 21 or the second main plane 22 about the middle of the first main plane 21 and the second main plane 22, and The first protrusions 41 are positioned symmetrically and have approximately the same shape and size as the first protrusions 41 . However, the concave curved surface 421 on the second protrusion 42 is turned outward by a certain angle α, preferably about 15 degrees, in a direction away from the imaginary plane than the concave curved surface 411 of the first protrusion 41 . This design is to make the light reflected by the concave curved surface 421 on the second protrusion 42 be reflected at a lower level than the light reflected by the concave curved surface 411 on the first protrusion 41, so that the second On the main plane 22 side, the light emitted by the second solid-state light source 32 can be projected to the front of the vehicle at a height substantially not higher than the level of the second solid-state light source 32 . This is to comply with the mandatory safety standards that usually apply to low beams in cars.

Various countries usually have mandatory safety standards for low beams of cars, including that the low beam beams on the side of the car (that is, the driver's side) cannot be projected higher than the level of the headlights, so as not to cause adjacent traffic when passing cars. The driver of the car on the opposite lane is disturbed by the dipped beam and causes an accident. Due to differences in road standards and automobile manufacturing standards in different countries, vehicles in some countries (such as the Commonwealth of Nations) drive on the left side of the road, while vehicles in some countries (such as China) drive on the right side of the road. Therefore, the regulations for the projection level of the left and right sides of the low beam beam may be different for automobile lights used in different countries. For countries where vehicles drive on the right side of the road (such as China, it is required that the horizontal height of the low beam beam projected to the left side of the vehicle is not higher than the height of the headlights), for this reason, as shown in Figure 4-5, the first protrusion 41 is arranged on the left side in the direction from the free end of the bearing part 2 of the vehicle lamp to the main body 1, and the second protrusion 42 is arranged on the right side so that the light reflected by the concave curved surface 421 of the second protrusion 42 Lights with a lower level are cast to the left in the direction the car is heading. For countries where the vehicle is driven on the left side of the road, the positions of the first protrusion 41 and the second protrusion 42 can be reversed, or the structure of the entire bulb can be mirrored with respect to the imaginary plane, so that the concave curved surface via the second protrusion 42 The light reflected by 421 with a lower level is projected to the right in the direction of travel of the car.

As shown in FIG. 2 and FIG. 6 , a sharp corner 412 is formed on the first protrusion 41 to block the light projected by the first solid-state light source 31 toward the direction opposite to the extending direction of the carrier 2 , and the second protrusion 42 also has a A sharp corner 422 is formed to block the light projected by the second solid-state light source 32 in a direction opposite to the extending direction of the carrier 2 . The sharp corners 412 and 422 may be walls extending substantially vertically from one end of the first protrusion 41 and the second protrusion 42 close to the main body 1 . The sharp corners 412 and 422 prevent the light emitted by the first solid-state light source 31 and the second solid-state light source 32 from irradiating backward to the reflective surface for high beam behind the lamp holder and being reflected to generate undesired glare. This further improves the quality of the low beam. An example of a structure for installing the first protrusion 41 and the second protrusion 42 is also shown in FIGS. 2 and 6 . The mounting plates 413 and 423 are connected to the first protrusion 41 and the second protrusion 42, respectively. Therefore, by fixing the mounting plates 413 and 423 to the first main plane 21 and the second main plane 22 respectively by screws or rivets, the first protrusion 41 and the second protrusion 42 can be fixed to the first protrusion 41 and the second protrusion 42 .

1-2 again, a third solid-state light source (not shown) is also provided on the first main plane 21, the third solid-state light source is spaced apart from the first protrusion 41 in the extending direction of the carrier and is smaller than the first protrusion 41. A protrusion 41 is closer to the main body 1; a fourth solid-state light source 34 is also provided on the second main plane 22, and the fourth solid-state light source 34 is spaced apart from the second protrusion 42 in the extending direction of the carrier 2 and is smaller than the second protrusion 42. The second protrusion 42 is closer to the main body 1 . The third solid-state light source and the fourth solid-state light source 34 are used as the high-beam light source of the car lamp, and the light generated by them is directly reflected by the reflective surface on the lamp holder and projected to the front of the car as a high-beam beam. Both the third solid-state light source and the fourth solid-state light source may also include a plurality of light-emitting units, such as a plurality of light-emitting diodes. Moreover, the third solid-state light source and the fourth solid-state light source also have substantially the same configuration, that is, have the same number of LED units, have the same luminous power, have the same size, and are installed on the first main plane 21 and the second main plane 21 respectively. The same position and orientation on the main plane 22, to produce beams of substantially the same intensity on the left and right sides of the bulb.

Since the first protrusion 41 and the second protrusion 42 are respectively arranged on the first main plane 21 and the second main plane 22 and are respectively close to the first solid-state light source 31 and the second solid-state light source 32, and have a relatively small size, they basically The light emitted by the third solid-state light source and the fourth solid-state light source will not be blocked. Therefore, the light emitted by the third solid-state light source and the fourth solid-state light source can be more reflected by the reflective surface of the lamp behind the bulb, so that the high beam provided by the bulb for the lamp has greater intensity and better performance. Uniformity of distribution.

As shown in FIGS. 1-3 , a light-shielding portion 23 is formed at the far end of the carrier 2 extending from the main body 1 to block the light emitted by the first solid-state light source 31 and the second solid-state light source 32 within a certain angle range from the direction in which the carrier 2 extends. The light emitted from inside (preferably not less than 40 degrees to the left and right of the extension direction). In this way, the light emitted by the light source can be avoided from projecting directly in front of the car to form a dazzling light beam. Advantageously, the carrier 2 can be directly formed into a shape that is flat in the middle and plump at both ends, for example, a shape formed by cutting out both sides of the middle of a cylinder. Circuit boards are respectively installed on both sides of the central flat portion to form a first main plane 21 and a second main plane 22, and a light-shielding portion 23 is formed on the column at the free end, and simultaneously because the whole carrier 2 can be made of a heat-conducting metal material ( For example, made of aluminum alloy), the larger mass and larger surface area of the plump cylinders at both ends can be used as a heat sink to conduct and dissipate the light generated by the work of multiple light sources on the first main plane 21 and the second main plane 22 of heat to improve the thermal performance of the bulb.

As shown in FIGS. 1-2 , in one embodiment, a radiator 6 is detachably connected to the side of the main body 1 opposite to the extending direction of the carrier 2 . The heat sink 6 can be detachably connected to the threaded rod 11 of the main body 1 of the bulb, for example by a threaded connection. Since the radiator 6 is detachably connected, when the bulb is installed on the lamp socket, the radiator 6 with a large volume may not be installed first, so as to facilitate the installation of the bulb. And after the bulb is installed in the lamp holder, the radiator 6 can be screwed on the threaded rod 11 of the main body 1 exposed from the rear of the lamp holder from the rear of the lamp holder, so as to realize from the carrier 2 to the radiator through the main body 1 6 thermal conduction paths.

The radiator 6 may have a chimney structure, that is, an airflow channel from the inlet 61 to the outlet 62, so that the heated air inside the radiator 6 can flow out quickly through the chimney effect and the cold outside air can flow in, so as to accelerate the heat dissipation of the radiator, Thereby improving the thermal performance of the bulb.

In addition, the main body 1 of the light bulb can also be provided with an installation part 5, so as to fix the light bulb in the lamp holder. The mounting part 5 is similar to the mounting part of a common halogen car light bulb, so it will not be repeated here.

The light bulb of the car light according to the embodiment of the present invention emits a low beam beam on one side of the bulb in the horizontal direction, which is basically below the level of the bulb, that is, has a clear beam cut-off line, and there is no area above the cut-off line. Glare area, so as to meet the mandatory safety requirements for low beam of headlights. The high-beam beam emitted by the bulb of the vehicle lamp in the embodiment of the present utility model has a relatively high intensity and a relatively uniform distribution of the beam. Therefore, the light bulb of the vehicle light according to the embodiment of the present invention can replace the traditional halogen light bulb as the light bulb of the headlight of the car.
