Fig. 2 is a schematic diagram illustrating a lamp system 20 including the lamp device 10 according to an embodiment of the invention. In some embodiments, the luminaire system 20 includes a luminaire device 10. The luminaire system 20 further comprises a substrate 2, a substrate 3, an optical element 333 and

light sources

22 and 33. In some embodiments, substrate 2 and substrate 3 and corresponding

light sources

22 and 33 may be packaged as one piece. In some embodiments, the base 2 and the base 3 may serve as substrates for carrying the corresponding

light sources

22 and 33.

In some embodiments,

light sources

11, 22, and 33 may be disposed on the same substrate. In some embodiments, at least some of

light sources

11, 22, and 33 are disposed on the same substrate.

As shown in fig. 2, in some embodiments, the substrate 2 is disposed adjacent to the substrate 1, and the light source 11 and the light source 22 respectively disposed on the substrate 1 and the substrate 2 are optically isolated from each other in the lamp system 20. In some embodiments, light isolation between light source 11 and light source 22 may be provided by a shielding member, which may be formed as a single member or may be formed by a protrusion on either the substrate (1 or 2) or the fixture structure. Therefore, the light beams between the

light sources

11 and 22 disposed on the

substrates

1 and 2 do not interfere with each other. In one embodiment, the shielding member includes a baffle 51, and the baffle 51 can block the light generated by the

light sources

11 and 22 disposed on the substrate 1 and the substrate 2 from interfering with each other.

The light source 22 emitting the first color light a1 is disposed on the substrate 2, and the first color light a1 of the light source 22 is transmitted toward the optical element 4. In one embodiment, the first color light a1 is directly emitted from the light source 22 onto the optical element 4. The first color light A1 emitted by the light source 22 is shifted to be the fourth color light A4 after passing through the optical element 4. First color light a1, second color light a2, third color light A3, and fourth color light a4 have different chromaticity coordinates on the CIE color space chromaticity diagram. In some embodiments, fourth color light a4 may be located within the red range in the CIE color space chromaticity diagram.

In some embodiments, light source 11 and light source 22 may emit light of substantially the same color. In some embodiments, light source 11 is the same as light source 22. In some embodiments, light source 11 and light source 22 both emit white light. In some embodiments, light source 11 is different from light source 22, but both emit white light. The first color light a11 of the light source 22 passes through the optical element 4, and the first color light a11 of the light source 11 passes through the optical element 111 and the optical element 4 to emit light beams with different chromaticity coordinates on the CIE color space chromaticity diagram, so that the lamp system 20 can generate light beams with different chromaticity coordinates with a low cost and a simple structure. In some embodiments, light source 22 is converted to red light by optical element 4; the first color light a11 of the light source 11 passes through the optical element 111 and the optical element 4 and is converted into amber, orange or yellow light.

In one embodiment, the substrate 3 and the substrate 1 may be disposed on both sides of the substrate 2. In one embodiment, the substrate 3 and the substrate 1 may be symmetrically disposed with respect to the substrate 2. A light source 33 can be disposed on the substrate 3, and in this embodiment, the light source 33 can be designed to emit a first color light A1. The optical element 333 is disposed on a path of the first color light a1 emitted by the light source 33, the first color light a1 can pass through the optical element 333, and the optical element 333 can shift the first color light a1 emitted by the light source 33 into the second color light a 2.

In some embodiments, light source 11, light source 22 are the same as light source 33. In some embodiments, light source 11, light source 22, and light source 33 all emit white light. In some embodiments, light source 11, light source 22, and light source 33 are partially different, but all emit white light.

In one embodiment, the substrate 3, the optical element 333 and the light source 33 of the lamp system 20 have a configuration similar to the substrate 1, the optical element 111 and the light source 11, so that the light for illumination and indication can be provided by the light source 11 and the light source 33 symmetrically to the substrate 2.

In some embodiments, in the lamp system 20, the

light sources

22 and 33 respectively disposed on the substrate 2 and the substrate 3 are optically isolated from each other in the lamp system 20, so that light beams between the

light sources

22 and 33 disposed on the substrate 2 and the substrate 3 do not interfere with each other. In one embodiment, a baffle plate 52 is disposed between the substrate 2 and the substrate 3, and the baffle plate 52 is used to isolate the light generated by the

light sources

22 and 33 disposed on the substrate 3 and the substrate 2.

In some embodiments, in the lamp system 20, the optical element 4 may have a single color, and the optical element 4 covers the light source 11, the optical element 111, the light source 22, the substrate 2, the light source 33, and the optical element 333 together. The monochromatic optical element 4 is easy to manufacture and low in cost, so that the lamp system 20 can emit light rays with different chromaticity coordinates with a low cost and a simple structure. In addition, the monochromatic optical element 4 is more beautiful, so that the overall texture and the beauty of the lamp system 20 can be improved. In one embodiment, the substrate 2 and the light source 22 are disposed at the position of the center line in the rear view of the vehicle, the combination of the substrate 1 and the optical element 111 and the combination of the substrate 3 and the optical element 333 are disposed on the left side and the right side of the substrate 2 and the light source 22, respectively, and the optical element 4 covers the optical element 111, the substrate 2 and the optical element 333 in the rear view of the vehicle. In some embodiments, the optical element 4 comprises a lamp shade. In some embodiments, the optical element 4 is a single red color.

Fig. 3 is a schematic view illustrating a lamp device 10 according to an embodiment of the invention, and fig. 4 is a cross-sectional view taken along line AA of fig. 3. In some embodiments, as shown in fig. 3 and 4, the optical element 111 is used to make the light of the light source 11 converge toward the irradiation direction as much as possible, thereby improving the brightness of the light projected toward the irradiation direction. The optical element 111 includes an incident surface 1111, an emergent surface 1112, and a lateral surface 1113. In some embodiments, the optical element 111 is gradually enlarged from the light incident surface 1111 to the light emitting surface 1112. The light incident surface 1111 is concave or spherical (but the invention is not limited thereto), so as to refract the incident light from the light source 11 and make the light go to the light emitting surface 1112 as far as possible. The light emitting surface 1112 may have a planar shape (but the invention is not limited thereto). The side surface 1113 can reflect the light rays with large lateral angles after entering the light incident surface 1111 toward the light emitting surface 1112. Side 1113 may function like a mirror. As shown in fig. 4, in some embodiments, the side surface 1113 of the optical element 111 is formed in a manner of gradually increasing from the light incident surface 1111 to the light emitting surface 1112. In some embodiments, side 1113 is tapered. In some embodiments, side 1113 is curved. In some embodiments, side 1113 is parabolic. In some embodiments, side 1113 is ellipsoidal. The light incident surface 1111 is concave or spherical, and the side surface 1113 can reflect the light rays with large lateral angles after entering the light incident surface 1111 toward the light emitting surface 1112, so that the optical element 111 can converge the light emitted from the light source 11, thereby increasing the brightness of the light source 11 irradiating in a desired direction. Although the optical element 111 is described in this paragraph, in some embodiments, the above description is also applicable to the optical element 333.

As shown in FIG. 4, in some embodiments, optical element 111 may be integrally formed by injection molding by mixing a transparent plastic with a green colorant. When light passes through the optical element 111, the colorant causes scattering of the light and shifts the color of the light, thereby generating light of a different color from the light emitted by the light source 11. Although the optical element 111 is taken as an example for the present embodiment, in some embodiments, the above description is also applied to the optical element 333.

Referring to FIG. 2, in one embodiment, for example, a white LED light source device capable of generating white light is used as the

light sources

11 and 33 of the present invention, the white light is shifted to green light by the green

optical elements

111 and 333, and the green light is mixed or shifted to amber, orange or yellow in accordance with vehicle regulations in the chromaticity coordinates within the ranges of the green boundary y ≦ x-0.120, the red boundary y ≧ 0.390, and the white boundary y ≧ 0.790-0.670x by the red optical element 4.

Fig. 5 is a perspective view illustrating a lamp device 10 according to an embodiment of the present invention, and fig. 6 is a schematic view illustrating a lamp system 20 including the lamp device 10 according to an embodiment of the present invention.

As shown in fig. 5 and 6, in an embodiment of the invention, the optical element 111 and the optical element 333 are omitted, and instead, the light source 11, the light source 22, the light source 33, and the optical element 4 disposed on the substrate 1, the substrate 2, and the substrate 3 respectively realize the light mixing function. In one embodiment, amber, orange or yellow according to the vehicle regulations can be achieved by only passing the

light source

11, 33 with a specific color light through the optical element 4.

As shown in FIGS. 5 and 6, in one embodiment, for example, a green LED light source device capable of generating green light can be used as the light source 11 and the light source 33 of the present invention instead of the green optical element 111 and the optical element 333 to shift the white light to green light in the embodiment 1, and the light directly passing through the green LED light source capable of generating green light can be mixed into amber, orange or yellow according to the vehicle regulations in the chromaticity coordinates within the ranges of the green boundary y ≦ x-0.120, the red boundary y ≧ 0.390, and the white boundary y ≧ 0.790-0.670x by the red optical element 4.

Referring to fig. 4, the optical element 4 includes an outer surface 41, and the light emitted from the

light sources

11 and 33 passes through the outer surface 41 and is emitted outward. In some embodiments, the outer surface 41 is curved. In some embodiments, the outer surface 41 is a curved surface that is concave toward the light fixture system 20. In some embodiments, the luminaire system 20 includes

optical elements

11 or 33, an

optical element

111 or 333, and a second light source 22. The second light source 22 generates light directly projected on the optical element 4. The

optical member

111 or 333 is used to shift the color of the light of the

first light source

11 or 33 before the light of the

first light source

11 or 33 is irradiated to the optical member 4, so that the light of the

first light source

11 or 33 transmitted through the optical member 4 is different in color from the light of the second light source 22. In some embodiments,

optical element

111 or 333 and optical element 4 are different colors. In some embodiments, the shade or optical element 4 is a single color. In some embodiments,

light source

11 or 33 and the cover 91. The light source 90 is not used for driving direction indication; i.e., a light source 90 to indicate the presence of a vehicle or a light on the vehicle width, or a light source 90 to inform other road users behind the vehicle that the driver is using the brakes. The cover 91 covers the light source 90. The paint 93 is disposed on the path of the cover 91 and the light source 90. The coating 93 is where the coating is clear but opaque, and the coating 93 comprises a white, off-white, light yellow, or goose-yellow color.
