Description

Car light structure and lamp cup structure thereof

The application is a divisional application of an invention patent application 'vehicle lamp structure and lamp cup structure' with application date of 2014, 3, 14 and application number of 201410096340.9.

Technical Field

The present invention relates to a vehicular lamp structure, and more particularly, to a vehicular lamp structure with multiple optical axes.

Background

Known light emitting modules of automotive headlamps can be classified into a tungsten halogen Lamp and an HID Lamp (high intensity Discharge Lamp), wherein the arc length of the tungsten halogen Lamp is 5.6 mm, and the arc length of the HID Lamp is 4.3 mm. In order to match with the conventional illumination light source, the light collecting system mostly adopts pes (projector inclined system), and the lamp cup has the characteristics of a single optical axis and a single light emitting module. At present, in order to simulate the arc length and size of a halogen tungsten filament and an HID lamp, a continuous crystal type light emitting diode packaging mode is adopted for a light emitting diode module arranged in an automotive headlamp, and only a single light emitting module can be used under the condition that a single ellipsoidal lamp cup only has a single focus, so that a light emitting diode with the size of 1 millimeter x 1 millimeter is mostly adopted as a base for packaging. The continuous type of the die-connected light emitting diode package refers to packaging the light emitting diode on the silicon substrate by a eutectic process or other processes, so that the distance between the dies of the light emitting diode can be 0.1 mm or even as small as 0.05 mm. Because the distance between the light emitting diodes is small, the light emitting diodes can be regarded as a continuous light emitting body. However, the continuous type of the die-connected light emitting diode package has a price more than 10 times that of the light emitting diode for illumination manufactured by the general manufacturing process under the same brightness.

Meanwhile, as shown in fig. 1, the package of the general light emitting diode for illumination is relatively large and cannot be packaged in a continuous crystal manner, and the light emitting diodes L1, L2, L3 and L4 are packaged on a Metal Core Printed Circuit Board (MCPCB). Generally, the minimum package margin R1 of the leds L1, L2, L3 and L4 is 0.15 mm to 0.2 mm, and the minimum solderable margin R2 of the leds L1, L2, L3 and L4 is 0.1 mm to 0.2 mm through a soldering process, so that if the leds for general illumination with a size of 1 mm × 1 mm are arranged in a dispersed manner, the distance R between the leds L1, L2, L3 and L4 is 0.5 mm to form a discontinuous light emitter, this manner will have a significant recess at the transition point on the Cut-off Line (Cut-off Line), and the left and right light emitting modules cannot be uniformly distributed or singly arranged on the right, so that the leds will not meet the requirements and regulations.

Detailed Description

[ first embodiment ]

First, referring to fig. 2A to 2D, a vehicle lamp structure V according to a first embodiment of the present invention includes a lamp cup structure 1 and a light emitting structure 2. The lamp cup structure 1 has a first cup surface 11 and a second cup surface 12, wherein the first cup surface 11 has a first focus F1 and a second focus F2, the second cup surface 12 has a third focus F3 and a fourth focus F4, the second focus F2 and the fourth focus F4 are overlapped, and the first cup surface 11 and the second cup surface 12 can be separated from each other by a predetermined distance. For example, the shape of the first cup surface 11 and the second cup surface 12 may be ellipse-based cup surfaces, and the lamp cup structure 1 may further have a light scattering cup surface 13 disposed or connected between the first cup surface 11 and the second cup surface 12, but the invention is not limited thereto.

Referring to fig. 2B, the first cup 11 may be composed of a first horizontal base line 111 and a first vertical base line 112, and the second cup may be composed of a second horizontal base line 121 and a second vertical base line 122. The first horizontal basic line 111, the first vertical basic line 112, the second horizontal basic line 121 and the second vertical basic line 122 may be formed by elliptical line segments, wherein the first horizontal basic line 111 and the first vertical basic line 112 may have a common first focus F1 or a common second focus F2, or may have different first focuses F1 and second focuses F2. Similarly, the second horizontal basic line 121 and the second vertical basic line 122 may have a common third focus F3 or a common fourth focus F4, or may have different third and fourth focuses F3 and F4. In addition, as shown in fig. 2B, the first vertical basic line 112 and the second vertical basic line 122 are disposed between the first horizontal basic line 111 and the second horizontal basic line 121, and there is no other vertical basic line or horizontal basic line (e.g., the first horizontal basic line) between the first vertical basic line 112 and the second vertical basic line 122.

Referring to fig. 2A, the light emitting structure 2 may be disposed in the lamp cup structure 1, and the light emitting structure 2 includes a first light emitting module 21 and a second light emitting module 22, where the first light emitting module 21 may include a plurality of first light emitting elements 211 for generating a first light source, or may have only one first light emitting element 211. The second light emitting module 22 may include a plurality of second light emitting elements 221 for generating the second light source, or may have only one second light emitting element 221. For example, the first light emitting element 211 and the second light emitting element 221 are light emitting diodes, wherein the first light emitting module 21 and the second light emitting module 22 can respectively adopt light emitting diodes with different color temperatures or color lights to adjust the light source emitted by the light emitting structure 2. When the plurality of first light emitting elements 211 are employed, at least one of the plurality of first light emitting elements 211 corresponds to the first focus F1, and when the plurality of second light emitting elements 221 are employed, at least one of the plurality of second light emitting elements 221 corresponds to the third focus F3. For example, at least one of the plurality of first light emitting elements 211 may be disposed adjacent to the first focus F1, and at least one of the plurality of second light emitting elements 221 may be disposed adjacent to the third focus F3. It is also possible to adopt a configuration in which at least one of the plurality of first light-emitting elements 211 is directly disposed at the first focal point F1 and at least one of the plurality of second light-emitting elements 221 is directly disposed at the third focal point F3. Further, at least one of the plurality of first light emitting elements 211 may be directly disposed on the first focus F1, and at least one of the plurality of second light emitting elements 221 may be disposed adjacent to the third focus F3. Therefore, the light type or illumination is changed by changing the positions of the light-emitting element and the focal point of the cup surface. In addition, the first light-emitting module 21 and the second light-emitting module 22 can control the first light-emitting module 21 and the second light-emitting module 22 to be turned on or off through a control module, so as to control the light source type, the color temperature or the color light emitted by the light-emitting structure 2. It should be noted that, the first light emitting module 21 and the second light emitting module 22 used in the present invention may be only one light emitting element, and are not limited to a plurality of light emitting elements, and the first light emitting module 21 and the second light emitting module 22 may also be a group of light emitting modules L in which a plurality of light emitting diodes are packaged on a substrate.

As shown in fig. 2C, when the control module turns on the light emitting structure 2, the first light source generated by the at least one first light emitting element 211 in the first light emitting module 21 is projected on the first cup surface 11 to form a first reflected light source passing through the second focal point F2, and the second light source generated by the at least one second light emitting element 221 in the second light emitting module 22 is projected on the second cup surface 12 to form a second reflected light source passing through the fourth focal point F4. In other words, since the first light emitting element 211 is correspondingly disposed at the first focal point F1, and the second light emitting element 221 is correspondingly disposed at the third focal point F3, the characteristics of the cup surface curve can make the first light source generated by the first light emitting element 211 focused on the second focal point F2 of the first cup surface 11 by the reflection of the first cup surface 11, and the second light source generated by the second light emitting element 221 focused on the fourth focal point F4 of the second cup surface 12 by the reflection of the second cup surface 12. In addition, the first and second reflective light sources can be irradiated through the plano-convex lens with a focus located at the second focus F2 and the fourth focus F4, at this time, the first cup surface 11 has a focusing function for the first light-emitting module 21, the first cup surface 11 has a light-diffusing function for the second light-emitting module 22, and conversely, the second cup surface 12 has a focusing function for the second light-emitting module 22, and the second cup surface 12 has a light-diffusing function for the first light-emitting module 21. The light diffusing cup surface 13 does not have a focusing function for the first light emitting module 21 and the second light emitting module 22, so that the first light emitting module 21 and the second light emitting module 22 generate a light diffusing effect.

As shown in fig. 2A to 2C, the lamp cup structure 1 may further include a first optical axis 14 and a second optical axis 15, the first optical axis 14 passes through the first focal point F1 and the second focal point F2 of the first cup surface 11, and the second optical axis 15 passes through the third focal point F3 and the fourth focal point F4 of the second cup surface 12. The first optical axis 14 and the second optical axis 15 intersect each other at the second focal point F2 and the fourth focal point F4, and the first optical axis 14 and the second optical axis 15 are coplanar with a plane formed by their corresponding vertical base lines. In addition, when the lamp cup structure 1 is configured and used with a plano-convex lens, the focal points of the plano-convex lens can be set at the second focal point F2 and the fourth focal point F4, so that the light source focused on the second focal point F2 and the fourth focal point F4 is emitted through the plano-convex lens, wherein the optical axis of the plano-convex lens is located between the first optical axis 14 and the second optical axis 15. In addition, the cutoff line shutter may be disposed adjacent to or directly at the focal point of the plano-convex lens, or adjacent to or directly at the second focal point F2 and the fourth focal point F4 of the lamp cup structure 1.

Referring to fig. 2D, by changing the curved surfaces of the first cup surface 11 and the second cup surface 12, the first focal point F1 of the first cup surface 11 is located between the second cup surface 12 and the third focal point F3, and the third focal point F3 of the second cup surface 12 is located between the first cup surface 11 and the first focal point F1. In the embodiment of fig. 2D, the lamp cup structure 1 may have only the first cup surface 11 and the second cup surface 12 without the light-scattering cup surface 13. In addition, when the lamp cup structure 1 is configured and used with a plano-convex lens, the focal points of the plano-convex lens can be set at the second focal point F2 and the fourth focal point F4, so that the light source focused on the second focal point F2 and the fourth focal point F4 can be emitted through the plano-convex lens, wherein the optical axis of the plano-convex lens is located between the first optical axis 14 and the second optical axis 15, and the cut-off line shutter can be disposed adjacent to or directly at the focal point of the plano-convex lens, or adjacent to or directly at the second focal point F2 and the fourth focal point F4 of the lamp cup structure 1.

Referring to fig. 2E, the light emitting module L shown in fig. 2E may be disposed in the lamp cup structure 1 shown in fig. 2A, or four separate light emitting diodes may be disposed in the lamp cup structure 1 respectively. The light emitting module L is composed of four 1 mm by 1 mm light emitting diodes L1, L2, L3 and L4, a distance R between the light emitting diodes L1, L2, L3 and L4 is 0.5 mm, the first optical axis 14 passes through the first focal point F1 and the second focal point F2 of the first cup 11, and the second optical axis 15 passes through the third focal point F3 and the fourth focal point F4 of the second cup 12. The first optical axis 14 passes through the light emitting diode L2, and the second optical axis 15 passes along the edge of the light emitting diode L3. Therefore, the led L2 forms a light-converging type for the first cup surface 11, and forms a light-diverging type for the second cup surface 12 because the second optical axis 15 does not pass through the led L2. In this embodiment, if the parameters used by the first cup surface 11 and the second cup surface 12 are that the distance from the vertex of the line segment of the first cup surface 11 (not the vertex of the light scattering cup surface 13) to the first focal point F1 is 10 mm, the distance from the vertex of the line segment of the second cup surface (not the vertex of the light scattering cup surface 13) to the third focal point F3 is 10 mm, the distance between the first focal point F1 and the second focal point F2 is 50 mm, and the distance between the third focal point F3 and the fourth focal point F4 is 50 mm, the design of the lamp cup structure 1 with a length of 35 mm can make the emitted light source conform to the light type of the regulations and can improve the illuminance and lumen count, and can also make the bright area concentrated, which is beneficial for making the low beam lamp irradiate farther.

Referring to fig. 3A, the lamp cup structure 1 is composed of a plurality of curved surfaces with different curvatures, for example, the first cup surface 11 may have a plurality of light-gathering arc surfaces, each light-gathering arc surface of the first cup surface 11 has an arc focus, the plurality of first light-emitting devices 211 are respectively disposed on the plurality of arc focuses, the second cup surface 12 may have a plurality of light-gathering arc surfaces, each light-gathering arc surface has an arc focus, and the plurality of second light-emitting devices 221 are respectively disposed on the plurality of arc focuses. Therefore, through all the respective focal points and optical axes of each light converging arc surface, the optical axis of each light converging arc surface is staggered on a common focal point F0, each light converging arc surface has a respective horizontal basic line and vertical basic line, and the focal point of the plano-convex lens is coincident with the common focal point F0.

Referring to fig. 3B, fig. 3B shows the relationship between the cutoff line shielding plate 4 and the first and second cup surfaces 11 and 12, the cutoff line shielding plate 4 is disposed on the second focal point F2 of the first cup surface 11 and the fourth focal point F4 of the second cup surface 12, and the second focal point F2 and the fourth focal point F4 are located at the intersection of the H-H line and the V-V line, so that the cutoff line shielding plate 4 shields the second focal point F2 and the fourth focal point F4. The cutoff shield 4 has a first horizontal portion 41 and a second horizontal portion 42, and the first horizontal portion 41 and the second horizontal portion 42 are connected by an inclined portion 43. The first horizontal portion 41 is located at the right side of the V-V line, and the plane (facing the lamp cup) of the first horizontal portion 41 coincides with the H-H line or is at a distance from the H-H line in the direction away from the lamp cup. The second horizontal portion 42 is located at the left side of the V-V line, and the plane of the second horizontal portion 42 is located above the H-H line, and shields some light reflected by the lamp cup structure 1. The inclined surface 43 between the first horizontal portion 41 and the second horizontal portion 42 is a transition of the cutoff line, which starts to transition at the V-V line, and the transition angle is about 165 degrees.

Referring to fig. 4A to 4D, the car light structure V uses different numbers of leds L1, L2, L3, L4, and L5, and corresponds to the focal points of the first cup 11 and the second cup 12 in different corresponding manners. As shown in fig. 4A, the light emitting module L is composed of three 1 mm by 1 mm light emitting diodes L1, L2, and L3, the first optical axis 14 can pass along the left or right edge of the light emitting diode L1, the second optical axis 15 can pass along the left or right edge of the light emitting diode L2, and the light emitting diode L3 is disposed on the central axis of the lamp cup structure 1. As shown in fig. 4B, the light emitting module L is composed of four 1 mm by 1 mm light emitting diodes L1, L2, L3 and L4, the first optical axis 14 can pass along the left or right edge of the light emitting diode L2, the second optical axis 15 can pass along the left or right edge of the light emitting diode L3, and the light emitting diodes L1 and L4 can serve as light diffusion functions.

As shown in fig. 4D, the light emitting module L is composed of five 1 mm by 1 mm light emitting diodes L1, L2, L3, L4 and L5, the first optical axis 14 can pass along the left or right edge of the light emitting diode L2, the second optical axis 15 can pass along the left or right edge of the light emitting diode L3, the light emitting diode L5 is disposed on the central axis of the lamp cup structure 1, and the light emitting diodes L1, L4 and L5 can serve as a light expanding function.

Referring to fig. 5, the lamp cup structure 1 may have a first cup surface 11 and a second cup surface 12, the first cup surface 11 may have a first light-gathering arc surface 113 and a second light-gathering arc surface 114, and the second cup surface 12 may have a third light-gathering arc surface 123 and a fourth light-gathering arc surface 124. The first light-gathering arc surface 113 has a first optical axis 14, the second light-gathering arc surface 114 has a second optical axis 15, the third light-gathering arc surface 123 has a third optical axis 16, and the fourth light-gathering arc surface 124 has a fourth optical axis 17. Then, the light emitting diodes L1 and L2 may be correspondingly disposed at the focal point of the first light converging arc surface 113 and the focal point of the third light converging arc surface 123. For example, the first optical axis 14 passes through the light emitting diode L1 (first light emitting element), the second optical axis 15 can pass along the left or right edge of the light emitting diode L1, the third optical axis 16 can pass along the left or right edge of the light emitting diode L2 (second light emitting element), and the fourth optical axis 17 can pass along the left or right edge of the light emitting diode L2.

The first optical axis 14 and the second optical axis 15 intersect each other at the second focal point F2 and the fourth focal point F4, and the first optical axis 14 and the second optical axis 15 are coplanar with a plane formed by their corresponding vertical base lines. However, the invention is not limited thereto.

Next, referring to fig. 2C, the light emitting device can be disposed in the lamp cup structure 1, so that the lamp cup structure 1 includes at least one first light emitting device 211 and at least one second light emitting device 221. Wherein the at least one first light emitting element 211 is adjacent to or disposed directly on the first focus F1 and the at least one second light emitting element 221 is adjacent to or disposed directly on the third focus F3 and F3.

As shown in fig. 4A to 4D, the light emitting diodes L1, L2, L3, L4 and L5 may be disposed in the lamp cup structure 1 according to the second embodiment of the present invention. The lamp cup structure 1 employs different numbers of leds L1, L2, L3, L4 and L5, and corresponds to the focal points of the first cup surface 11 and the second cup surface 12 in different corresponding manners. As shown in fig. 4A, the light emitting module L is composed of three 1 mm by 1 mm light emitting diodes L1, L2, and L3, the first optical axis 14 can pass along the left or right edge of the light emitting diode L1, the second optical axis 15 can pass along the left or right edge of the light emitting diode L2, and the light emitting diode L3 is disposed on the central axis of the lamp cup structure 1. As shown in fig. 4B, the light emitting module L is composed of four 1 mm by 1 mm light emitting diodes L1, L2, L3 and L4, the first optical axis 14 can pass along the left or right edge of the light emitting diode L2, and the second optical axis 15 can pass along the left or right edge of the light emitting diode L3. As shown in fig. 4C, the light emitting module L is composed of four 1 mm by 1 mm light emitting diodes L1, L2, L3 and L4, the first optical axis 14 passes through the light emitting diode L2, and the second optical axis 15 can pass along the left or right edge of the light emitting diode L3. As shown in fig. 4D, the light emitting module L is composed of five 1 mm by 1 mm light emitting diodes L1, L2, L3, L4 and L5, the first optical axis 14 can pass along the left or right edge of the light emitting diode L2, the second optical axis 15 can pass along the left or right edge of the light emitting diode L3, and the light emitting diode L5 is disposed on the central axis of the lamp cup structure 1. It should be noted that the arrangement of the leds L1, L2, L3, L4, and L5 is not limited to the horizontal arrangement as shown in fig. 4A to 4D, and as shown in fig. 4C, the leds L1 and L2 are disposed on the left side of the symmetry axis, the led L2 is disposed on the first optical axis 14 and not directly disposed on the first focal point F1, but disposed adjacent to the first focal point F1, and the led L1 is disposed on the left side of the first optical axis 14 and behind the led L2. Therefore, when the leds L1 and L2 are disposed adjacent to each other in the first focal point F1, the light sources projected by the leds L1 and L2 through a plano-convex lens can be darker than the light sources projected by the leds L1 and L2 directly disposed on the first focal point F1. Further, the leds L3 and L4 are disposed on the right side of the symmetry axis, the led L3 is disposed adjacent to the third focal point F3, the second optical axis 15 passes along the left side of the led L3, and the center point of the led L3 is disposed on the line connecting the first focal point F1 and the third focal point F3.

Therefore, the light source projected by the light emitting diodes L1, L2, L3 and L4 passing through the plano-convex lens can meet the ECE R112 regulation and project a light source pattern with darker left side and brighter right side.

The lamp cup structure 1 provided by the second embodiment of the present invention can be designed by the curvature of each light-gathering arc surface of the first cup surface 11 and the second cup surface 12 in the lamp cup structure 1, and the light-emitting structure 2 is correspondingly disposed at the focus of each light-gathering arc surface, which is particularly suitable for a discontinuous light-emitting diode package structure.

[ third embodiment ]

Referring to fig. 6A, a third embodiment of the invention provides a vehicular lamp structure V, which includes a lamp cup structure 1, a light emitting structure 2 and a reflector 5. The third embodiment is similar to the lamp cup structure 1 in the first and second embodiments, and the greatest difference between the third embodiment and the first embodiment is that the positions of the first light-emitting module 21 and the second light-emitting module 22 can have corresponding positions with the central axis of the lamp cup structure 1 by changing the curvatures of the first light-gathering arc surface 113 and the second light-gathering arc surface 114 on the first cup surface 11. For example, the lamp cup structure 1 has a first light-focusing arc surface 113 and a second light-focusing arc surface 114 connected to the first light-focusing arc surface 113, the first light-focusing arc surface 113 has a first focal point F1 and a second focal point F2, the second light-focusing arc surface 114 has a third focal point F3 and a fourth focal point F4, and the second focal point F2 and the fourth focal point F4 are coincident with each other. The light emitting structure 2 includes a first light emitting module 21 and a second light emitting module 22, wherein the first light emitting module 21 may include a plurality of first light emitting elements 211 for generating a first light source, or may have only one light emitting element, and the second light emitting module 22 may include a plurality of second light emitting elements 221 for generating a second light source, or may have only one light emitting element. At least one of the plurality of first light emitting elements 211 corresponds to the first focus F1, and at least one of the plurality of second light emitting elements 221 corresponds to the third focus F3. In addition, in the third embodiment, a reflector 5 may be disposed between the first light emitting module 21 and the second light emitting module 22 and adjacent to the second light emitting module 22 to reflect the light source of the light emitting module. Therefore, by the arrangement of the first and second light-gathering arc surfaces 113 and 114 and the first and second light-emitting

modules

21 and 22, the first light source generated by the at least one first light-emitting element 211 is projected on the first light-gathering arc surface 113 to form a first reflected light source passing through the second focal point F2, a part of the second light source generated by the at least one second light-emitting element 221 is directly projected on the second light-gathering arc surface 114 to form a second reflected light source passing through the fourth focal point F4, and another part of the second light source generated by the at least one second light-emitting element 221 is reflected by the reflector 5 and the second light-gathering arc surface 114 in sequence to form a third reflected light source passing through the fourth focal point F4. In the present embodiment, the reflector 5 may reflect the light originally reflected to the first light-condensing arc surface 113 to the second light-condensing arc surface 114. The light reflected by the reflector 5 is the light emitted from the virtual image of the second light emitting module 22 in the reflector 5, and therefore, the light can be focused on the second focal point F2 and the fourth focal point F4. For example, if the third focal point F3 of the second light-focusing arc surface 114 is located at the boundary between the second light-emitting module 22 and the reflector 5, the light from the second light-emitting module 22 and the light from the virtual image fall on two sides of the fourth focal point F4.

In addition, the lamp cup structure 1 may be further configured with a plano-convex lens 3, and the focal point of the plano-convex lens 3 may be set at the second focal point F2 and the fourth focal point F4, so that the light source focused at the second focal point F2 and the fourth focal point F4 is emitted through the plano-convex lens 3, wherein the optical axis of the plano-convex lens 3 is located between the first optical axis 14 and the second optical axis 15.

Referring to fig. 6B, the light emitting structure 2 is disposed in the lamp cup structure 1 in the present embodiment, wherein the light emitting structure 2 includes a first light emitting module 21 and a second light emitting module 22, the first light emitting module 21 includes a plurality of first light emitting elements 211 for generating a first light source, the second light emitting module 22 includes a plurality of second light emitting elements 221 for generating a second light source, the first light emitting elements 211 and the second light emitting elements 221 are composed of four light emitting diodes L1, L2, L3, and L4 with a thickness of 1 millimeter, wherein the first light emitting elements 211 and the second light emitting elements 221 are discontinuous light sources, and a distance between grains of the light emitting diodes L1, L2, L3, and L4 may be 0.2 mm to 5 mm.

Referring to fig. 2A, the lamp cup structure 1 in the third embodiment may be similar to the lamp cup structure 1 in the first embodiment or the second embodiment. In the third embodiment, the first cup surface 11 has a first light-gathering arc surface 113 and a second light-gathering arc surface 114, the second cup surface 12 has a third light-gathering arc surface 123 and a fourth light-gathering arc surface 124, the first light-gathering arc surface 113 has a first optical axis 14, the second light-gathering arc surface 114 has a second optical axis 15, the third light-gathering arc surface 123 has a third optical axis 16, and the fourth light-gathering arc surface 124 has a fourth optical axis 17. The first optical axis 14 passes through the leds L2 of the first and second

light emitting modules

21 and 22, the third optical axis 16 can pass along the left or right edges of the leds L3 of the first and second

light emitting modules

21 and 22, and the second optical axis 15 and the fourth optical axis 17 can pass along the left or right edges of the leds L2 and L3 of the first and second

light emitting modules

21 and 22, but the invention is not limited thereto. Further, according to the present invention, if the luminous intensity of the vehicular lamp structure V is to be enhanced, more groups of light emitting modules may be disposed, so that the light source irradiated by the light emitting modules has higher illuminance or lumen count and the irradiation distance of the light source can be increased.

In addition, the first light-emitting module 21 and the second light-emitting module 22 can be controlled to be turned on or off by a control module, so as to control the light source type, color temperature or color light emitted by the light-emitting structure 2. Therefore, if leds with different color lights are used together, light sources with different colors can be mixed, and for example, a warm white light of 3000K can be mixed with a blue light of about 460 nm to obtain a white light with other color temperatures. It can also be used to match up with warm white light of 3000K and cool white light of 6500K, and to match up with light color of about 4000K.

The lamp cup structure 1 provided by the third embodiment of the present invention can be designed by the curvature of each light-gathering arc surface of the first cup surface 11 and the second cup surface 12 in the lamp cup structure 1, and the light-emitting structure 2 is correspondingly disposed at the focus of each light-gathering arc surface, which is particularly suitable for a discontinuous light-emitting diode package structure.
