[0002] In order to adjust the light distribution curve of the light-emitting device, the light-emitting device in the prior art usually includes a device bracket, a light-emitting chip and a lens. The device bracket is usually provided with a groove, and the light-emitting chip is arranged at the bottom of the groove and located in the groove. The lens is usually bonded to the device bracket by adhesive and covers the opening of the groove so that the lens can receive the light emitted by the light-emitting chip and adjust the emission angle of the light.

[0050] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0053] like Figure 1 and Figure 2As shown, the present invention provides a device bracket 1, including a bracket base 10 and an annular dam 11, one side of the bracket base 10 has a setting surface 10a, the setting surface 10a is provided with a first groove 101, the annular dam 11 is arranged on the setting surface 10a along the opening of the first groove 101, and the dam space 11a in the annular dam 11 is connected with the space in the first groove 101 to form a cup-shaped groove 12.

[0054] By providing an annular dam 11 along the opening of the first groove 101, the annular dam 11 can be used to form a shield at the periphery of the opening of the first groove 101, so as to prevent the adhesive on the periphery of the annular dam 11 from directly overflowing into the interior of the annular dam 11 and the opening of the first groove 101, thereby reducing the possibility of the adhesive overflowing into the dam space 11a of the annular dam 11 and the first groove 101 (i.e., the cup-shaped groove 12), so as to improve the controllability of the actual light-emitting effect of the light-emitting device 100 using the device bracket 1 provided by the present invention.

[0055] In addition, since the annular dam 11 protrudes from the setting surface 10a, and the lens 3 of the light-emitting device 100 needs to be bonded to the setting surface 10a, the annular dam 11 can also be engaged with the lens 3 to limit the lens 3 through the annular dam 11, thereby improving the assembly accuracy of the lens 3 and the device bracket 1, so as to improve the controllability of the adjustment effect of the lens 3 on the light emitted from the cup-shaped groove 12, so as to further improve the controllability of the actual light output effect of the light-emitting device 100 using the device bracket 1 provided by the present invention.

[0056] The device support 1 may further include a conductive structure 13, which is disposed on the support base 10, and a portion of the conductive structure 13 is located at the bottom of the cup-shaped groove 12, so as to be connected to the light-emitting chip 2 in the cup-shaped groove 12 (see Figure 5 ) are electrically connected, and a conductive structure 13 is also partially located on the side of the support base 10 away from the annular dam 11 for being electrically connected to an external control circuit, so that the light-emitting chip 2 can be electrically connected to the external control circuit through the conductive structure 13.

[0057] Please combine Figure 3As shown, along the radial direction of the cup-shaped groove 12, the annular dam 11 has a thickness d1. The larger the thickness d1, the better the structural strength of the annular dam 11. However, the larger the area of ​​the setting surface 10a occupied by the annular dam 11 on the setting surface 10a, when the size of the setting surface 10a is limited, it is not conducive to ensuring that there is a sufficient effective bonding area between the lens 3 and the device bracket 1, so that the connection stability between the lens 3 and the device bracket 1 is worse. Therefore, the thickness d1 cannot be too large. Based on this, optionally, the thickness d1 of the annular dam 11 can satisfy: 0.25mm≤d1≤0.5mm. For example, the thickness d1 can be 0.25mm, 0.27mm, 0.3mm, 0.32mm, 0.35mm, 0.37mm, 0.4mm, 0.42mm, 0.45mm, 0.47mm or 0.5mm, etc.

[0058] In order to accommodate the light-emitting chip 2 of the light-emitting device 100 in the cup-shaped groove 12 and to make the light emission angle of the light-emitting chip 2 from the cup mouth 120 of the cup-shaped groove 12 larger, usually, optionally, the diameter r1 of the cup mouth 120 of the cup-shaped groove 12 can satisfy: 1.2mm≤r1≤1.8mm, for example, the diameter r1 of the cup mouth 120 can be 1.2mm, 1.25mm, 1.3mm, 1.35mm, 1.4mm, 1.45mm, 1.5mm, 1.55mm, 1.6mm, 1.65mm, 1.7mm, 1.75mm or 1.8mm, etc.

[0059] The annular dam 11 has a protruding height h protruding from the bottom of the first groove 101. The greater the protruding height h, the better the blocking effect of the annular dam 11 on the adhesive, and the more it can reduce the possibility of the adhesive overflowing into the cup-shaped groove 12. However, the shielding effect of the annular dam 11 on the cup-shaped groove 12 is also greater. In the process of using manufacturing equipment to set the light-emitting chip 2 in the cup-shaped groove 12 and perform wire bonding, the annular dam 11 is more likely to interfere with the operating head of the manufacturing equipment. Therefore, the protruding height h cannot be too large. Based on this Optionally, the protruding height h of the annular dam 11 protruding from the bottom of the first groove 101 may satisfy: 0.65mm≤h≤0.8mm, for example, the protruding height h may be 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, 0.7mm, 0.71mm, 0.72mm, 0.73mm, 0.74mm, 0.75mm, 0.76mm, 0.77mm, 0.78mm, 0.79mm or 0.8mm, etc.

[0060] Optionally, the inner wall surface of the annular dam 11 and the end surface of the annular dam 11 away from the bracket base 10 are connected by a transition arc surface 110, so that on the one hand, the transition between the inner wall surface of the annular dam 11 and the end surface of the annular dam 11 can be smooth, which is beneficial to avoid stress concentration at the connection between the inner wall surface of the annular dam 11 and the end surface of the annular dam 11 when injection molding the annular dam 11, and can reduce the difficulty of demolding the device bracket 1. On the other hand, when using the manufacturing equipment to set the light-emitting chip 2 in the cup-shaped groove 12 and perform wire bonding, the operating head of the manufacturing equipment can be further avoided.

[0061] Optionally, the outer peripheral surface of the annular dam 11 and the end surface of the annular dam 11 away from the bracket base 10 are connected by a transition arc surface 110, so that on the one hand, the transition between the outer peripheral surface of the annular dam 11 and the end surface of the annular dam 11 can be smooth, which is beneficial to avoid stress concentration at the connection between the outer peripheral surface of the annular dam 11 and the end surface of the annular dam 11 when injection molding the annular dam 11, and can reduce the difficulty of demolding the device bracket 1. On the other hand, in the process of clamping the annular dam 11 to the lens 3, the transition arc surface 110 can play a certain guiding role, so that when the annular dam 11 is not fully aligned with the lens 3, it can abut against the lens 3 through the transition arc surface 110 to guide the annular dam 11 to be aligned and clamped with the lens 3.

[0062] The transition arc surface 110 has a curvature radius r2. The larger the curvature radius r2, the smoother the transition of the transition arc surface 110. However, the larger the setting space required for the transition arc surface 110, the larger the curvature radius r2 of the transition arc surface 110. Therefore, the curvature radius r2 of the transition arc surface 110 cannot be too large. Based on this, optionally, the curvature radius r2 of the transition arc surface 110 can satisfy: 0.2mm≤r2≤0.6mm. For example, the curvature radius r2 can be 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm or 0.6mm, etc.

[0063] Optionally, the annular dam 11 has an outer diameter r3, and the outer peripheral surface of the annular dam 11 is inclined so that the outer diameter r3 of the part of the annular dam 11 that is farther away from the bracket base 10 is smaller, so that the outer peripheral surface of the annular dam 11 can play a certain guiding role in the process of snapping the annular dam 11 to the lens 3, so that when the annular dam 11 is not fully aligned with the lens 3, the outer peripheral surface of the annular dam 11 can abut against the lens 3 to guide the annular dam 11 to be aligned and snapped with the lens 3.

[0064] Optionally, the cup-shaped groove 12 has a diameter r4, and the groove wall of the cup-shaped groove 12 is inclined, so that the diameter r4 of the cup-shaped groove 12 closer to the cup mouth 120 of the cup-shaped groove 12 is larger, thereby reducing the shielding effect of the annular dam 11 on the cup-shaped groove 12, so that when using manufacturing equipment to set the light-emitting chip 2 in the cup-shaped groove 12, perform wire bonding, etc., the operating head of the manufacturing equipment can be further avoided.

[0065] It can be understood that the diameter r4 at the cup mouth 120 of the cup-shaped groove 12 is equal to the aforementioned diameter r1 of the cup mouth 120 .

[0066] In other embodiments, the groove wall surface of the cup-shaped groove 12 may also be parallel to the extension direction S of the central axis 101a of the groove, so that the light emitted from the cup-shaped groove 12 to the lens 3 can be more concentrated, so as to provide better light distribution for the lens 3.

[0067] Optionally, the inner wall surface of the annular dam 11 forms an angle θ1 with the extension direction S of the central axis 101a of the first groove 101, and the side wall surface of the first groove 101 forms an angle θ2 with the extension direction S of the central axis 101a of the first groove 101, θ1=θ2, in other words, the inner wall surface of the annular dam 11 and the side wall surface of the first groove 101 are connected to form a surface, so that the structure of the device bracket 1 is simpler and easy to manufacture. Among them, θ1 and θ2 can both be 0°, or, θ1 and θ2 can both be greater than 0°.

[0068] Optionally, the setting surface 10a is also provided with a plurality of glue overflow grooves 102, which are arranged at intervals and located on the outer periphery of the annular dam 11, so that on the one hand, the glue overflow grooves 102 can be used to accommodate glue to reduce the total amount of glue overflowing to the annular dam 11, and the possibility of glue overflowing into the cup-shaped groove 12 can be further reduced. On the other hand, the effective connection area between the glue and the device bracket 1 can be increased, so as to improve the connection stability of the lens 3 bonded to the device bracket 1 by the glue.

[0069] Optionally, at least part of the glue overflow groove 102 passes through the outer peripheral surface of the bracket base 10 , so that the glue can further overflow to the outer peripheral side of the bracket base 10 through the glue overflow groove 102 to further reduce the possibility of the glue overflowing into the cup-shaped groove 12 .

[0070] The overflow glue groove 102 has a width d2. The smaller the width d2 is, the less glue the overflow glue groove 102 can accommodate. However, the larger the width d2 is, the larger the setting space occupied by a single overflow glue groove 102 is, and the fewer the number of overflow glue grooves 102 that can be set on the limited setting surface 10a is, and the overall improvement effect of multiple overflow glue grooves 102 on the effective connection area between the device bracket 1 and the glue is smaller. Therefore, the width d2 cannot be too small or too large. Based on this, optionally, the width d2 of the overflow glue groove 102 can satisfy: 0.1mm≤d2≤0.3mm, for example, the width d2 can be 0.1mm, 0.12mm, 0.14mm, 0.15mm, 0.16mm, 0.18mm, 0.2mm, 0.22mm, 0.24mm, 0.25mm, 0.26mm, 0.28mm or 0.3mm, etc.

[0071] Optionally, the length of the glue overflow groove 102 extends along the radial direction of the first groove 101 , and a plurality of glue overflow grooves 102 are arranged at intervals around the first groove 101 , thereby facilitating the glue to overflow along the radial direction of the first groove 101 and fill the glue overflow grooves 102 .

[0072] The length directions of two adjacent glue overflow grooves 102 form an angle θ3. The larger the angle θ3 is, the larger the spacing between the two adjacent glue overflow grooves 102 is, and the fewer the number of glue overflow grooves 102 that can be set on the limited setting surface 10a is. However, the smaller the angle θ3 is, the more glue overflow grooves 102 are set on the setting surface 10a, the more complex the structure of the device bracket 1 is, and when the lens 3 is bonded to the device bracket 1 by glue, the larger the amount of glue required is. Therefore, the angle θ3 cannot be too small or too large. Based on this, optionally, the angle θ3 of the length directions of two adjacent glue overflow grooves 102 can satisfy: 20°≤θ3≤45°. For example, the angle θ3 can be 20°, 22°, 25°, 27°, 30°, 32°, 35°, 37°, 40°, 42° or 45°, etc.

[0073] Optionally, the device bracket 1 also includes a limiting boss 103, which is arranged on the setting surface 10a, and the limiting boss 103 is spaced apart on the outer periphery of the annular dam 11, so that the relative position of the lens 3 and the device bracket 1 can be limited from the outer periphery of the lens 3 by the limiting boss 103, so as to further improve the assembly accuracy of the lens 3 and the device bracket 1, and thereby improve the controllability of the adjustment effect of the lens 3 on the light emitted from the cup-shaped groove 12.

[0074] In an optional embodiment, the height of the annular dam 11 protruding from the setting surface 10a is higher than the height of the limiting boss 103 protruding from the setting surface 10a, so that when the glue climbs along the outer peripheral surface of the annular dam 11 and the surface of the limiting boss 103 to a height exceeding the limiting boss 103, under the principle of a communicating vessel, the glue is more likely to continue to overflow to the top of the limiting boss 103, which helps to further reduce the possibility of the glue overflowing into the cup-shaped groove 12.

[0075] In another optional implementation, the height of the annular dam 11 protruding from the setting surface 10a is flush with or lower than the height of the limiting boss 103 protruding from the setting surface 10a, which can make the height of the limiting boss 103 higher to enhance the limiting effect of the limiting boss 103 on the lens 3 from the periphery of the lens 3.

[0076] Typically, the outer peripheral contour of the lens 3 is circular, so optionally, the boss has a limiting surface 103a facing the annular dam 11, and the limiting surface 103a is an arc surface that is concave in the direction away from the annular dam 11, so that the shape of the limiting surface 103a can be more adapted to the outer peripheral surface shape of the lens 3, so that the limiting surface 103a has a better limiting effect on the lens 3.

[0077] Optionally, the setting surface 10a is rectangular, and the device bracket 1 includes four limiting bosses 103, and the four limiting bosses 103 are spaced apart from each other and respectively arranged at the four corners of the setting surface 10a, so that on the one hand, the lens 3 can be limited by the four limiting bosses 103 together, and the limiting effect is better. On the other hand, since the part of the setting surface 10a area that needs to be connected with the lens 3 is usually in a circular ring shape, such a setting can reduce the occupation of the limiting boss 103 on the part of the setting surface 10a area that needs to be connected with the lens 3.

[0078] like Figure 4 and Figure 5 As shown, the present invention also provides a light-emitting device 100, including a light-emitting chip 2, a lens 3 and a device bracket 1 as described in the aforementioned technical solution, the light-emitting chip 2 is arranged at the bottom of the first groove 101 and is located in the cup-shaped groove 12, the lens 3 is provided with a second groove 30, the lens 3 is bonded to the setting surface 10a by adhesive, and the annular dam 11 is engaged and snap-fitted into the second groove 30. By using the aforementioned device bracket 1, the possibility of adhesive overflowing into the groove and affecting the light emission of the light-emitting chip 2 can be reduced, thereby improving the controllability of the actual light emission effect of the light-emitting device 100.

[0079] In addition, by making the annular dam 11 cooperate with and snap-fit ​​into the second groove 30 of the lens 3, the lens 3 can be limited by the annular dam 11, thereby improving the assembly accuracy of the lens 3 and the device bracket 1, so as to improve the controllability of the adjustment effect of the lens 3 on the light emitted from the cup-shaped groove 12, so as to further improve the controllability of the actual light output effect of the light-emitting device 100.

[0080] The light emitting chip 2 can be electrically connected to a portion of the conductive structure 13 located at the bottom of the cup-shaped groove 12 , so that the light emitting chip 2 can be electrically connected to an external control circuit through the conductive structure 13 .

[0081] Optionally, the material of the lens 3 is silicone, so that on the one hand, the lens 3 has high light transmittance and refractive index, can better adjust the light, and the light loss is small in the process of light passing through the lens 3. On the other hand, the lens 3 can have a certain elasticity, so that the lens 3 is less likely to be damaged due to bumps, and the lens 3 can be elastically clamped to the annular dam 11, so that the clamping stability between the lens 3 and the annular dam 11 is better.

[0082] Please combine Figure 6 As shown, optionally, when the light-emitting chip 2 is powered on, the light-emitting device 100 is intercepted by a virtual cross section passing through the central axis 101a of the first groove 101, and any virtual cross section is within a light-emitting angle range of at least 130°, and the relative light intensity of the light-emitting device 100 is greater than or equal to 50%, and the light intensity distribution curve of the light-emitting device 100 on the virtual cross section has two peaks, so that the light-emitting angle of the light-emitting device 100 is large, and the light-emitting intensity in the large angle direction is also large, such as Figure 6 As shown, Figure 6 exemplarily shows a light intensity distribution curve of the light emitting device 100 on a virtual cross section, wherein it is shown that within a light emitting angle range of approximately 135°, the relative light intensity of the light emitting device 100 is greater than or equal to 50%, and the light intensity distribution curve has two peaks.

[0083] In addition, it should be noted that Figure 6 In the figure, the light intensity data of the light emitting device 100 is normalized, that is, the distribution change of the light intensity is described by the relative value of the light intensity at each angle and the light intensity peak value. Therefore, it can be understood that when the light intensity is the peak value of the light intensity distribution curve, the relative light intensity is 1, and when the light intensity is 50% of the maximum peak value of the light intensity distribution curve, the relative light intensity is 0.5.

[0084] In order to enable the light-emitting device 100 to achieve the aforementioned light-emitting effect, optionally, the lens 3 can be formed into a structure in which the middle part of the outer surface is concave and the outer part of the middle part bulges outward to form a curved surface, so that the light emitted from the middle part can be reduced through the concave middle part of the lens 3, and the light can be diverged through the outer part of the middle part, so that the relative light intensity of the light-emitting device 100 is greater than or equal to 50% of the light-emitting angle, and the light intensity distribution curve on the virtual cross section has two peaks.

In particular, when a plurality of light-emitting devices 100 as described in the above technical solution are arranged on the substrate 200, the light-emitting effect of different positions of the light-emitting device can be more consistent. Among them, the substrate 200 can be provided with a control circuit, and the conductive structure 13 of the light-emitting device 100 (please refer to Figure 5 As shown) can be electrically connected to the control circuit on the substrate 200.
