Description

Vehicle lamp device and light distribution method thereof

The present invention relates to a vehicle lamp device and a light distribution method thereof, and more particularly to a vehicle lamp device having a shape of switching distance and distance lights and a light distribution method thereof.

First, the light-emitting modules of conventional headlamps for automobiles can be divided into tungsten halogen lamps and HID lamps (High Intensity Discharge Lamp). Among them, the tungsten filament lamp has a filament length of 5.6 mm. The arc length is 4.3 mm. In order to match the traditional lighting source, most of its light collection systems use a single optical axis and a single light emitting module. At present, the light-emitting diode modules installed in the headlights of automobiles are used to simulate the length and size of the tungsten tungsten filament and the arc length of the HID lamp. They are continuously packaged in continuous crystal light-emitting diodes. In the case of a single optical axis and a single focus, only a single light emitting module can be used. Therefore, currently, a light emitting diode with a size of 1 mm * 1 mm is used as a basis for packaging. The continuous continuous-type light-emitting diode packaging mode refers to packaging multiple light-emitting diode chips on a silicon substrate through a eutectic process or other processes, so that the light-emitting diode crystal chips (wafers) , Chip) The distance between each other can be 0.2 mm or less, or even less than 0.05 mm. Since the distance between the plurality of light emitting diodes is small, the light emitting diodes can be regarded as a continuous light emitting body. However, such a continuous continuous-type light-emitting diode package, at the same brightness, is more than 10 times more expensive than a light-emitting diode manufactured by a general process. That is, the light-emitting diodes for lighting packaged in the general process do not need to imitate the light-emitting behavior of filaments or arcs, so they are non-continuous crystals, which is a single light-emitting diode crystal ( Chip (chip) directly package, or two or Three or more light emitting diodes are directly packaged. In other words, the light-emitting diode packaged in the non-connected crystal mode refers to the distance between the crystal grains of each light-emitting diode greater than 0.2 mm or 0.5 mm, or even the crystal of each light-emitting diode. The distance between grains can be up to 4 mm.

Next, the conventional light emitting module of a headlight for a vehicle generally has a switching function of a near light and a far light for the use of the driving field of vision. As shown in FIGS. 16 and 17, FIG. 16 is a schematic diagram of a conventional vehicle light device, and FIG. 17 is a schematic diagram of a light shape projection generated by a conventional vehicle light device. The conventional vehicle headlamp has a low-light lamp cup P1, a long-light lamp cup P2, a light-dark cut-off shield P3, and a lens P4. The low-light lamp cup P1 and the far-light lamp cup P2 respectively have a first focus and a second focus corresponding to the first focus, and the lens P4 has a lens focus Q. The low-light lamp cup P1 and the far-light lamp cup P2 respectively have a second focal point and a lens focal point Q of the lens P4 that coincide with each other. However, such a vehicle light device with three focal points overlapping each other will produce a light-shaped projection diagram as shown in FIG. 17 when the high light is turned on, that is, a dark band region G is formed between two light sources.

In addition, as in Patent Publication No. US 8,545,073, "Lighting module and device for vehicle with improved high-beam function" patent, in order to overcome the dark band The generation of the region G. US Patent No. 8,545,073 uses a "beam bender 8" that is "ideally infinitely thin" to avoid the generation of the dark band region G. However, since the beam deflector is a substantial object and cannot be presented in an infinitely thin manner, there will still be a dark band region G in the light projection diagram as shown in FIG. 17.

The shielding structure is disposed between the first reflective structure and the second reflective structure. The shielding structure has a first outer surface, a second outer surface opposite to the first outer surface, and a connection. At the cut-off edge of the first outer surface and the second outer surface.

Both sides of the reflective plate 54 have a side end portion (not labeled) extending toward the second outer surface 52 and are disposed on the second outer surface 52. The two side ends are connected to the second outer surface 52 of the shielding structure 5. Further, a through-hole 55 is formed between the reflective plate 54 and the second outer surface 52, whereby part of the light generated by the second reflective structure 2 can pass through the through-hole 55 and be projected onto one of the lens structures 6. In the area, a part of the light can be reflected by the reflecting surface (not labeled) of the reflecting plate 54 and projected onto another area of the lens structure 6.

In addition, the lens structure 6 further includes a convex portion 66. The convex portion 66 may be a structure provided on a light incident surface 67 of the lens structure 6 and protruding from the light incident surface 67. In addition, the convex portion 66 has a convex portion focus 661 (see FIG. 13). It should be noted that the relationship among the reflection portion 16, the reflection plate 54, and the convex portion 66 will be described later.

Next, please refer to FIG. 6 and timely match with FIG. 7 to FIG. 9. It should be noted that the following describes the travel paths of light generated by the first light emitting structure 3 and the second light emitting structure 4, and the first reflective structure. 1. The relationship between the second reflective structure 2, the first light emitting structure 3, the second light emitting structure 4, the shielding structure 5 and a lens structure 6. The relationship between the three reflection portions 16, the reflection plate 54 and the convex portion 66 and the aforementioned first reflection structure 1 and the first light emitting structure 3 will be described later.

Specifically, the lens structure 6 is a lens structure 6 having multiple focal points. In the embodiment of the present invention, the lens structure 6 has a first lens focal point 61, a second lens focal point 62, and a third lens focal point 63. In addition, the lens structure 6 defines a major axis A, a horizontal axis 64, and a vertical axis 65 orthogonal to the horizontal axis 64 that pass through the light incident surface 67 of the lens structure 6 and pass through a light emitting surface 68 of the lens structure 6. And a focal plane F1. The focal plane F1 is parallel to a plane formed by the intersection of the horizontal axis 64 and the vertical axis 65 (for example, the light incident surface 67), and the focal plane F1 passes through the cut-off edge 53 of the shielding structure 5 or near the cut-off edge 53 of the shielding structure 5. In addition, the first lens focal point 61 is set on the focal plane F1 or near the focal plane F1 (not shown in the figure, for the sake of explanation, FIG. 9 illustrates the first lens focal point 61 on the focal plane F1 for illustration), And the first lens focus 61 is located on the cut-off edge 53 of the shielding structure 5 or near the cut-off edge 53 of the shielding structure 5 (not shown in the figure, for convenience of illustration, FIG. 9 sets the first lens focus 61 on the cut-off edge 53). It is described above), that is, in other embodiments, the first lens focal point 61 may be separated from the cut-off edge 53 by a predetermined interval W (see FIG. 13). The size of the predetermined interval W may be between 0 millimeters (mm) and 10 millimeters (mm). In addition, the main axis A may pass through the cut-off edge 53 of the shielding structure 5 or near the cut-off edge 53, that is, the main axis A is adjacent to the cut-off edge 53. In addition, the main axis A may pass through the first lens focus 61 or the vicinity of the first lens focus 61 at the same time.

It is worth noting that both the second lens focal point 62 and the third lens focal point 63 are located at Below the shielding structure 5, that is, the second lens focus 62 and the third lens focus 63 are disposed away from the first outer surface 51 and the second outer surface 52 of the shielding structure 5, and the second lens focus 62 and the third lens The distance between the focal point 63 and the first outer surface 51 is greater than the distance between the second lens focal point 62 and the third lens focal point 63 to the second outer surface 52. Furthermore, the second lens focal point 62 and the third lens focal point 63 may be set on the focal plane F1 or not on the focal plane F1 according to the light shape to be generated. Incidentally, the distance from the second lens focal point 62 to the cut-off edge 53 is smaller than the distance from the third lens focal point 63 to the cut-off edge 53. Furthermore, the lens structure 6 has a first light transmission area Z1 corresponding to the first lens focus 61, a second light transmission area Z2 corresponding to the second lens focus 62, and a third light transmission area 63 The third light penetrates the area Z3. The first light transmission region Z1 is disposed between the second light transmission region Z2 and the third light transmission region Z3.

Next, the first reflective structure 1 has a first focal point 11 formed by an elliptic curved surface and a second focal point 12 corresponding to the first focal point 11 of the first reflective structure 1. The first light emitting structure 3 may correspond to the first focus 11 of the first reflective structure 1. Preferably, the first light emitting structure 3 may be disposed on the first focus 11 of the first reflective structure 1. However, it should be noted that the first light-emitting structure 3 may also be located adjacent to the first focus 11 of the first reflective structure 1 according to the light shape to be generated, and the present invention is not limited thereto.

Preferably, as shown in FIG. 12 and combined with FIG. 9, in order to make the light source generated when the near-light is turned on sufficiently bright, the first reflection structure 1 may further include a third focus point 13 and A fourth focal point 14 corresponding to the third focal point 13 of the first reflective structure 1, and the second focal point 12 of the first reflective structure 1 and the fourth focal point 14 of the first reflective structure 1 coincide with each other. In addition, two sets of the first light-emitting structures 3 may be respectively disposed on the first focus 11 and the third focus 13 of the first reflection structure 1 (in other words, if the present invention is shown in FIG. 3, the first focus 11 and the third focus 13 They are respectively located on two sets of first light-emitting structures (two light-emitting diode modules) 3). In this way, the light generated by the two sets of first light emitting structures 3 can be projected to the second focus point 12 and the fourth focus point 14 And the cut-off edge 53, that is, the first reflected light beam 32 can be projected onto the first lens focal point 61, and the first reflected light beam 32 is projected onto the first light transmission region Z1 of the lens structure 6. In other words, the first reflective structure 1 may be an ellipsoidal reflective cup structure having multiple focal points.

Thereby, when one set of the first light-emitting structures 3 is directly disposed on the first focus 11 of the first reflective structure 1, a first light 31 generated by the first light-emitting structure 3 can be projected on the first reflective structure 1. To form a first reflected light 32 passing through the second focus 12 of the first reflective structure 1. It is worth noting that when another group of first light emitting structures 3 is disposed on the third focal point 13 of the first reflective structure 1, a first light 31 generated by the first light emitting structure 3 can be projected on the first reflective structure 1. To form a first reflected light 32 passing through the fourth focus 14 of the first reflective structure 1. In addition, it is mentioned that although the first light-emitting structures 3 shown in the drawings of the embodiment of the present invention have two groups in total, the two groups of the first light-emitting structures 3 can be arranged close enough to make the first reflective structure 1 The first focal point 11 is located between the two groups of first light emitting structures 3. In other words, only one set of the first light-emitting structures 3 may be provided, so that the light source center point of the set of the first light-emitting structures 3 is located on the first focus 11 and the main axis A of the first reflective structure 1, which is not the present invention limit.

Continuing the above, as shown in FIG. 12, taking a non-interconnected light emitting diode as an example, a predetermined distance T may be set between the two groups of first light emitting structures 3, and the predetermined distance T may be between 0.2 mm and 4 mm. Or between 0.5 mm and 4 mm. Specifically, when the two sets of the first light emitting structures 3 are individually packaged single light emitting diode chips, the predetermined distance T between the two light emitting diode chips may be between 0.2 mm and 4 mm. Or between 0.5 mm and 4 mm. In addition, it is worth noting that although two sets of first light-emitting structures 3 are shown in FIG. 13, two light-emitting diode chips can also be packaged in the same package, and the two light-emitting diodes can be made. The predetermined pitch T between the body wafers is between 0.2 mm and 4 mm or between 0.5 mm and 4 mm. In other words, the two sets of first light emitting structures 3 may be respectively disposed on the first focus 11 and the third focus 13 of the first reflection structure 1. With this, the light emitting diode chip The package with a relatively long distance can greatly reduce the cost of the light emitting structure. However, in other embodiments, the line connecting the first focus 11 and the second focus 12 may be located on the side of the corresponding first light emitting structure 3, and the line connecting the third focus 13 and the fourth focus 14 may be located The sides of the corresponding first light-emitting structure 3, in other words, neither of these two lines can pass through the two groups of first light-emitting structures 3. It is worth noting that the first reflective structure 1 and the second reflective structure 2 may be further formed by more ellipsoidal curves with different curvatures, so that the focus of the first reflective structure 1 and the second reflective structure 2 can be more There are more, so that more groups of the first light-emitting structures 3 and the second light-emitting structures 4 can be provided, and the groups of the first light-emitting structures 3 and the groups of the second light-emitting structures 4 respectively correspond to the focal points.

In addition, please refer to FIG. 3 at the same time. If a continuous-type light-emitting diode is used as an example, the first light-emitting structure 3 may have multiple light-emitting diode wafers, and the distance between each light-emitting diode wafer may Between 0 mm and 0.2 mm or between 0 mm and 0.5 mm.

As described above, in other words, the distance between the first focal point 11 and the third focal point 13 of the first reflective structure 1 may be between 0 mm to 0.2 mm, between 0 mm to 0.5 mm, and from 0.2 mm to 4 mm. Between 0.5 mm and 4 mm. Preferably, it can be between 0.2 mm and 4 mm or between 0.5 mm and 4 mm.

Then, when the first light-emitting structure 3 and the second light-emitting structure 4 located in the first reflective structure 1 and the second reflective structure 2 are lit at the same time, they can be used as the high-beam light of the vehicle light device V. Specifically, the second reflective structure 2 also has a first focal point 21 formed by an elliptic curved surface, a second focal point 22 corresponding to the first focal point 21 of the second reflective structure 2, and a third focal point formed by an elliptical curved surface. The focal point 23 is a fourth focal point 24 corresponding to the third focal point 23. In addition, a first focal point 21 of the second reflective structure 2 and a third focal point 23 of the second reflective structure 2 are provided corresponding to each other. The second light emitting structure 4 may correspond to the first focal point 21 of the second reflective structure 2 and the third focal point 23 of the second reflective structure 2. Preferably, in the embodiment of the present invention, the first focal point 21 of the second reflective structure 2 and the third focal point 23 of the second reflective structure 2 may coincide with each other. The light source center point can be directly set on the first focus point 21 and the third focus point 23 of the second reflection structure 2. However, it should be noted that the second light-emitting structure 4 can also be located adjacent to the first focus 21 and the third focus 23 of the second reflection structure 2 according to the light shape to be generated, which is not the present invention. limit.

Therefore, when the second light-emitting structure 4 is directly disposed on the first focus 21 and the third focus 23 of the second reflection structure 2, a second light 41 generated by the second light-emitting structure 4 can be projected on the second reflection structure. 2 to form a second reflected light 42 passing through the second focus 22 of the second reflective structure 2.
