Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor light emitting, and in particular relates to a multi-color light source device with zoned light distribution. Background Art

[0002] Multi-color light sources usually integrate multiple different light-emitting chips. Different light-emitting chips need to have different divergence angles, spot sizes, etc. due to different colors, functions, and optical effects. Figure 5-6 At least two light-emitting chips 2 (a first light-emitting chip 21 and a second light-emitting chip 22) are mounted within the bracket 1, covered with a transparent adhesive layer 3. This layer 3 serves the following functions: 1. It encapsulates the light-emitting chips 2; 2. It modifies the color of the emitted light; and 3. It improves light extraction efficiency. A lens 4 is placed atop this layer, which is used for optical shaping.

[0003] The problem is that the first and second light-emitting chips 21, 22 are not optically shaped in different areas, resulting in a light output that cannot meet the needs of the application scenario. Even if an optical lens 4 is provided above the transparent adhesive layer 3, the entire light source is essentially optically adjusted in the same manner. There is no optical design that differentiates the first and second light-emitting chips 21, 22, resulting in low compatibility with the light-emitting chip 2, making it difficult to achieve multiple divergence angles within the same light source device.

[0004] Based on the above, the current problem to be solved is to provide a multi-chip zoned light control, which can emit a variety of divergence angles with precise angle control and good structural stability. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-color light source device with zoned light distribution, aiming to solve the problems in the prior art of no zoned light control, inability to emit light at multiple divergent angles, poor light control effect and poor product stability.

[0006] The utility model is implemented as follows: a multi-color light source device with zoned light distribution includes:

[0007] Bracket;

[0008] A light-emitting chip, which is provided on the bracket and includes at least a first light-emitting chip and a second light-emitting chip;

[0009] a light-transmitting adhesive layer, which is provided on the bracket and covers the first light-emitting chip and the second light-emitting chip;

[0010] a lens disposed on the bracket and covering the light-transmitting adhesive layer; the lens comprising a first optical functional area and a second optical functional area respectively corresponding to the first light-emitting chip and the second light-emitting chip; the first optical functional area comprising a second optical interface for outputting light, and the second optical functional area comprising a fourth optical interface for outputting light;

[0011] An optical isolation cavity is provided between the first optical functional area and the second optical functional area; and first reflective surfaces are provided on the four sides of the optical isolation cavity.

[0012] The extended line AA' of the outline of the first reflective surface on the first optical functional area side does not intersect with the fourth optical interface; the extended line BB' of the outline of the first reflective surface on the second optical functional area side does not intersect with the second optical interface.

[0013] Furthermore, the distance between the highest point of the second optical interface and the upper surface of the first light-emitting chip is H1, and the distance between the highest point of the fourth optical interface and the upper surface of the second light-emitting chip is H2, satisfying 2.0mm≤H1≤3.0mm and 2.0mm≤H2≤3.0mm.

[0014] Furthermore, the first optical functional area includes a first optical interface for inputting light and a second reflective surface for reflecting light;

[0015] The second optical functional area includes a third optical interface for inputting light and a third reflecting surface for reflecting light;

[0016] A first cavity and a second cavity are respectively provided on the outer sides of the second reflecting surface and the third reflecting surface. Air and / or a light-transmitting adhesive layer are provided in the first cavity and the second cavity.

[0017] Furthermore, the distance between the first optical interface and the upper surface of the first light-emitting chip is d1, and the distance between the third optical interface and the upper surface of the second light-emitting chip is d2, satisfying d1≥0.05mm and d2≥0.05mm.

[0018] Furthermore, the straight-line heights of the second reflecting surface and the third reflecting surface in the optical axis direction are h1 and h2, respectively, and 0.1 mm≤h1≤1 mm and 0.1 mm≤h2≤1 mm.

[0019] Furthermore, the bracket is higher than the first optical interface and the third optical interface, so that the first optical interface and the third optical interface extend into the bracket and are tightly fitted with the light-transmitting adhesive layer.

[0020] Furthermore, the first light-emitting chip and / or the second light-emitting chip is covered with a fluorescent adhesive layer, and the light-transmitting adhesive layer covers the fluorescent adhesive layer.

[0021] Furthermore, a protruding structure for reinforcement is provided inside the optical isolation cavity.

[0022] Furthermore, air and / or a light-transmitting adhesive layer is provided in the optical isolation cavity.

[0023] Furthermore, the divergence angles at 1 / 5 of the light intensity formed by the first light-emitting chip and the second light-emitting chip after the lens satisfy the following requirements: 60° to 140° in the horizontal direction, 30° to 90° in the vertical direction, and 60° to 140° in the diagonal direction.

[0024] Compared with the prior art, the multi-color light source device with zoned light distribution provided by the present invention has the following beneficial effects:

[0025] The optical isolation cavity 5 of the present invention divides the light source device into at least two optical functional areas. The first optical functional area 41 and the second optical functional area 42 are respectively adapted to the first light-emitting chip 21 and the second light-emitting chip 22, and each has an independent optical design, so that the same light source device can emit light with multiple divergence angles and multiple colors.

[0026] By setting the first reflective surface 51 of the optical isolation cavity 5, the high-angle edge light of the first and second optical functional areas 41, 42 can be reflected in the direction of their respective optical axes Z, thus partitioning the light, solving the problem of light crosstalk between different optical functional areas, and significantly improving the light efficiency. At the same time, the extended lines AA' and BB' of the contour lines on both sides of the first reflective surface 51 are set to not intersect with the fourth optical interface 422 and the second optical interface 412. This ensures that the light emitted by the first light-emitting chip 21 is completely reflected in the direction of the optical axis Z of the first optical functional area 41 after being acted upon by the first reflective surface 51 on the side of the first optical functional area 41, and the light emitted by the second light-emitting chip 22 is completely reflected in the direction of the optical axis Z of the second optical functional area 42 after being acted upon by the first reflective surface 51 on the side of the second optical functional area 42. This effectively prevents light mixing, truly achieving precise zoning and light control, excellent light collection effect, and compact size.

[0027] The protruding structure 52 inside the optical isolation cavity 5 increases the connection area between the lens 4 and the light-transmitting adhesive layer 3, making the connection between the two more stable and greatly improving the stability of the entire structure.

[0028] By providing the second reflecting surface 413 and the third reflecting surface 423 , the light energy utilization rate of each optical functional area is further improved, the light collecting effect is good, and the light control is precise.

[0029] The bracket 1 is arranged higher than the first optical interface 411 and the third optical interface 421, so that the first optical interface 411 and the third optical interface 421 extend into the bracket 1 and fit tightly against the transparent adhesive layer 3. This ensures a stable connection between the lens 4 and the transparent adhesive layer 3 and significantly reduces the size of the device.

[0030] By setting the distances from the light input interface and light output interface of the lens 4 to the light-emitting chip 2, as well as the reflection channel lengths of the second reflection surface 413 and the third reflection surface 423, precise light control can be achieved to meet the needs of application scenarios. For example, the divergence angle at 1 / 5 of the light intensity can meet the following requirements: 60° to 140° in the horizontal direction, 30° to 90° in the vertical direction, and 60° to 140° in the diagonal direction.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0041] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.

[0042] The multi-color light source device of the utility model with partitioned light distribution comprises a bracket 1, a light emitting chip 2, a light-transmitting adhesive layer 3, a lens 4 and an optical isolation cavity 5. Figure 1 .

[0043] The light emitting chip 2 is provided on the bracket 1 and includes at least a first light emitting chip 21 and a second light emitting chip 22. The first light emitting chip 21 and the second light emitting chip 22 can be provided with the same light emitting color or with different light emitting colors.

[0044] The light-transmitting adhesive layer 3 is provided on the bracket 1 and tightly covers the side and upper surfaces of the first light-emitting chip 21 and the second light-emitting chip 22, as well as the inside of the bowl of the bracket 1. The light-transmitting adhesive layer 3 can improve light extraction. Wavelength conversion particles can also be set in the light-transmitting adhesive layer 3 to change the color of the light output; light diffusion particles can also be set to make the light output uniform. Figure 2 A fluorescent adhesive layer 6 may be added between the transparent adhesive layer 3 and the first light-emitting chip 21, or / and between the transparent adhesive layer 3 and the second light-emitting chip 22 to change the light emission color of the first light-emitting chip 21 or / and the second light-emitting chip 22. Of course, light diffusion particles may also be added to the fluorescent adhesive layer 6.

[0045] The lens 4 is arranged on the bracket 1 and tightly covers at least a certain area of ​​the transparent adhesive layer 3 directly above the first light-emitting chip 21 and the second light-emitting chip 22, and is used to optically shape the output light of the first light-emitting chip 21 and the second light-emitting chip 22 to achieve a preset divergence angle, spot shape and uniformity.

[0046] The optical isolation cavity 5 is a cavity structure in which the lens 4 is recessed toward the interior of the lens 4 on the side near the light-transmitting adhesive layer 3. The optical isolation cavity 5 has an opening on the side facing the light-transmitting adhesive layer 3. The optical isolation cavity 5 is disposed between the first light-emitting chip 21 and the second light-emitting chip 22. The optical isolation cavity 5 divides the lens 4 into at least a first optical functional area 41 and a second optical functional area 42. The first and second optical functional areas 41 and 42 are disposed above the first and second light-emitting chips 21 and 22, respectively. The first optical functional area 41 includes a first optical interface 411 for inputting light and a second optical interface 412 for outputting light. The second optical functional area 42 includes a third optical interface 421 for inputting light and a fourth optical interface 422 for outputting light. The first and second optical functional areas 41 and 42 are preferably convex lenses 4, while the second and fourth optical interfaces 412 and 422 are planes or free-form surfaces. The third and fourth optical interfaces 421 and 422 can be planes or free-form surfaces.

[0047] Preferably, the optical isolation cavity 5 does not block the upper surfaces of the first light emitting chip 21 and the second light emitting chip 22. The four sides of the optical isolation cavity 5 are configured as first reflective surfaces 51 for reflecting the edge high-angle light emitted by the first light emitting chip 21 and the second light emitting chip 22.

[0048] Specifically, in the first embodiment of the first reflective surface 51 , the first reflective surface 51 is set as a vertical plane parallel to the optical axis Z of the first light-emitting chip 21 or the second light-emitting chip 22 , that is, the cross section of the optical isolation cavity 5 is substantially rectangular.

[0049] The second embodiment of the first reflective surface 51: Figure 1 The first reflective surface 51 is a plane or curved surface inclined at a certain angle to the optical axis Z of the first light-emitting chip 21 or the second light-emitting chip 22, that is, the cross-section of the optical isolation cavity 5 is trapezoidal. When the cross-section of the optical isolation cavity 5 is trapezoidal, its cross-section gradually decreases along the light-transmitting adhesive layer 3 toward the lens 4.

[0050] On a cross-sectional plane passing through the optical axis Z, the extended line AA' of the outline of the first reflective surface 51 on the first optical functional area 41 side does not intersect the fourth optical interface 422, meaning that the extended line AA' is positioned outside the fourth optical interface 422. On a cross-sectional plane passing through the optical axis Z, the extended line BB' of the outline of the first reflective surface 51 on the second optical functional area 42 side does not intersect the second optical interface 412, meaning that the extended line BB' is positioned outside the second optical interface 412. By setting the tilt angle of the first reflective surface 51, the present invention effectively prevents light crosstalk and achieves precise zoned light control.

[0051] There are several ways to fill the optical isolation cavity 5:

[0052] Method 1: The optical isolation cavity 5 is completely filled with air.

[0053] Method 2: The optical isolation cavity 5 is filled with a combination of a light-transmitting adhesive layer 3 and air. Preferably, the lower part of the optical isolation cavity 5 is filled with a light-transmitting adhesive layer 3 and the upper part is filled with air. Figure 1 .

[0054] Method 3: The optical isolation cavity 5 is completely filled with the light-transmitting adhesive layer 3, refer to Figure 2 .

[0055] The refractive index of the lens 4 is greater than that of the air and the transparent adhesive layer 3. When the edge light of the first light-emitting chip 21 and the second light-emitting chip 22 is incident on the side of the optical isolation cavity 5 at a large angle, that is, the light propagates from the optically dense medium to the optically combing medium, when the incident angle satisfies a critical angle or greater, total internal reflection is likely to occur. Figure 4 Light emitted by the first light-emitting chip 21 and the second light-emitting chip 22 passes through the first reflective surface 51 on the side of the optical isolation cavity 5 and propagates toward the direction of the optical axis Z close to the first optical functional area 41 and the second optical functional area 42, respectively. This effectively partitions the light, significantly reducing light mixing between the first optical functional area 41 and the second optical functional area 42, and achieves zoned light control and excellent light collection. The optical isolation cavity 5 divides the light source device into at least two optical functional areas (the first optical functional area 41 and the second optical functional area 42). The first optical functional area 41 and the second optical functional area 42 are respectively adapted to the first light-emitting chip 21 and the second light-emitting chip 22, and are optically independently designed for the first optical functional area 41 and the second optical functional area 42 to achieve zoned light control, allowing the same light source device to emit light with multiple divergence angles and multiple colors in a compact size.

[0056] In addition, the optical isolation cavity 5 of the present invention also has the function of storing light-transmitting glue. Figure 1-2On the one hand, in the process of forming the light-transmitting glue layer 3, the light-transmitting glue can be squeezed into the optical isolation cavity 5. Because of the existence of the optical isolation cavity 5, the tolerance of the glue amount is improved, which makes the production difficulty smaller and avoids the situation where bubbles in the light-transmitting glue layer 3 affect the light output effect; on the other hand, because the light-transmitting glue is filled into the optical isolation cavity 5, the connection between the light-transmitting glue layer 3 and the lens 4 is more firmly established.

[0057] The interior of the optical isolation cavity 5 is provided with a raised structure 52 for reinforcement. This structure is connected to the transparent adhesive layer 3, increasing the connection area between the lens 4 and the transparent adhesive layer 3, thereby strengthening the connection and significantly improving the stability of the entire structure. The bottom of the raised structure 52 can be positioned below, equal to, or above the light input interfaces (first optical interface 411 and third optical interface 431) of the first and second optical functional areas 42, 42, as needed. As long as the raised structure 52 is connected to the transparent adhesive layer 3, it will provide reinforcement.

[0058] Furthermore, the first optical interface 411 and the third optical interface 421 are respectively provided with an inverted-cone-shaped second reflective surface 413 and a third reflective surface 423 on their four edges. The second reflective surface 413 and the third reflective surface 423 are used to reflect light at a large angle.

[0059] The refractive index of lens 4 is greater than that of the light-transmitting adhesive layer 3 and greater than that of air. The high-angle edge light emitted by the first light-emitting chip 21 and the second light-emitting chip 22 is incident on the second reflective surface 413 and the third reflective surface 423, respectively. After total reflection, it propagates in the direction of the optical axis Z of the first optical functional area 41 and the second optical functional area 42, respectively. This effectively improves the utilization rate of light energy, facilitates optical shaping, and easily achieves a preset divergence angle, resulting in a good light shaping effect. A first cavity 43 and a second cavity 44 are respectively provided on the outer sides of the second reflective surface 413 and the third reflective surface 423. Air and / or the light-transmitting adhesive layer 3 are provided within the first cavity 43 and the second cavity 44. The functions of the first cavity 43 and the second cavity 44 are: 1. to form the second reflective surface 413 and the third reflective surface 423; 2. to accommodate the light-transmitting adhesive layer 3, thereby increasing the connection area between the lens 4 and the light-transmitting adhesive layer 3 and enhancing the stability of the device.

[0060] Preferably, the bracket 1 is higher than the first optical interface 411 and the third optical interface 421, so that the first optical interface 411 and the second reflective surface 413, the third optical interface 421, and the third reflective surface 423 on both sides of the optical isolation cavity 5 extend into the bracket 1 and connect with the light-transmitting adhesive layer 3. This provides a more stable connection between the lens 4 and the light-transmitting adhesive layer 3 and also reduces the height of the light source device. The optical isolation cavity 5 is preferably higher than the light-transmitting adhesive layer 3 and the bracket 1. The first optical functional area 41 and the second optical functional area 42 can be configured differently based on the different first and second light-emitting chips 21 and 22. For example, when the size of the first light-emitting chip 21 is larger than the size of the second light-emitting chip 22, the area of ​​the first optical interface 411 can be set to be larger than the second optical interface 412. The third optical interface 421 is set to be higher than the fourth optical interface 422. The third optical interface 421 is set to be higher than the fourth optical interface 422.

[0061] The height of the first optical functional area 41 and the second optical functional area 42 is proportional to the size of the light-emitting chip 2. The top-view areas of the first optical functional area 41 and the second optical functional area 42 are proportional to the size of the light-emitting chip 2. That is, the larger the size of the light-emitting chip 2 corresponding to the first optical functional area 41 or the second optical functional area 42, the higher the height and the larger the area.

[0062] Further optimization plan, refer to Figure 3 The distance between the first optical interface 411 and the upper surface of the first light-emitting chip 21 is d1, and the distance between the third optical interface 421 and the upper surface of the second light-emitting chip 22 is d2. d1 and d2 satisfy: d1 ≥ 0.05 mm, d2 ≥ 0.05 mm.

[0063] The linear heights of the second reflecting surface 413 and the third reflecting surface 423 in the direction of the optical axis Z are h1 and h2, respectively. h1 and h2 satisfy the following conditions: 0.1 mm ≤ h1 ≤ 1 mm, 0.1 mm ≤ h2 ≤ 1 mm.

[0064] The distance H1 from the highest point of the first optical functional area 41 (second optical interface 412) to the upper surface of the first light-emitting chip 21 is measured, and the distance H2 from the highest point of the second optical functional area 42 (fourth optical interface 422) to the upper surface of the second light-emitting chip 22 is measured. H1 and H2 satisfy the following conditions: 2.0 mm ≤ H1 ≤ 3.0 mm, and 2.0 mm ≤ H2 ≤ 3.0 mm.

[0065] By setting the distances between the light input interface (first optical interface 411, third optical interface 421) and the light output interface (second optical interface 412, fourth optical interface 422) of the lens 4 and the light-emitting chip 2, as well as the reflection channel lengths of the second reflection surface 413 and the third reflection surface 423, the emitted light accurately reaches a preset angle, achieving precise light control. The divergence angle at 1 / 5 of the light intensity is achieved as follows: 60° to 140° in the horizontal direction (X-axis direction), 30° to 90° in the vertical direction (Y-axis direction), and 60° to 140° in the diagonal direction. The X-axis and Y-axis are defined as plane rectangular coordinate axes to meet the needs of application scenarios.

[0066] This does not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
