[0035] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0036] Below, reference is made to Figures 1-9 Describe the LED unit 10 according to an embodiment of the present utility model. The LED unit 10 is applied to a vehicle. For example, a vehicle lamp.

[0037] As Figures 1-4 shown, the LED unit 10 according to the present utility model includes: a substrate 11, a lens 12, and a light source 13. The lens 12 has a bottom surface facing the substrate 11. The bottom surface is disposed on the substrate 11. The focal point of the lens 12 is located on the bottom surface. The light source 13 is disposed on the substrate 11. The light source 13 is disposed on the lens 12.

[0038] It can be understood that the substrate 11, the lens 12, and the light source 13 constitute the main structure of the LED unit 10. The lens 12 has a bottom surface and a diverging surface. The bottom surface is located on the substrate 11, so that the lens 12 can be connected to the substrate 11. Moreover, the focal point of the lens 12 is located on the bottom surface, so that the lens 12 bracket can be omitted, and the diverging angle of the lens 12 can be ensured to meet the lighting requirements. The lens 12 is directly connected to the substrate 11, which can save material costs and facilitate the installation between the lens 12 and the substrate 11. The light source 13 is located on the substrate 11, and the light source 13 is connected to the bottom surface, so that the substrate 11 can provide an installation position for the light source 13 and the lens 12, and further facilitate the encapsulation between the substrate 11, the lens 12, and the light source 13. The light source 13 is diverged through the lens 12, so as to meet the lighting requirements of the LED unit 10. For example, the size of the LED unit 10 depends on the size of the lens 12. The smaller the size of the lens 12, the faster the light efficiency decreases. And ensuring that the light efficiency is more than 40%, and further the size of the LED unit 10 can be reduced according to the size of the lens 12.

[0039] Thus, by setting the bottom surface of the lens 12 on the substrate 11, the lens 12 bracket can be omitted, and further the encapsulation steps and material costs can be saved. Moreover, the focal point of the lens 12 is located on the bottom surface, and the light source 13 is arranged on the substrate 11, so that the light source 13 can be diverged through the lens 12, and further facilitate the lighting of the LED unit 10.

[0040] Among them, as Figure 2 shown, the bottom surface is a plane, and the light source 13 is embedded in the lens 12. That is to say, the bottom surface of the lens 12 is constructed as a plane, so that the bottom surface can be adhesively connected to the substrate 11, and further facilitate the encapsulation between the lens 12, the light source 13, and the substrate 11. The light source 13 is arranged in the lens 12, and the light source 13 is nested close to the bottom surface, so that the light source 13 can be close to the focal point of the lens 12, and further meet the diverging requirements of the lens 12 for the light source 13, and also facilitate the encapsulation between the substrate 11, the lens 12, and the light source 13. A light source nesting part is arranged on one side of the lens 12 facing the substrate 11, and the light source 13 is arranged in the light source nesting part, so that the lens 12 and the light source 13 can be nested and matched.

[0041] Particularly, as Figure 2As shown, the light source 13 has a light-emitting surface and a backlight surface that are opposite to each other in the thickness direction of the light source 13. The light-emitting surface is located inside the lens 12, and the backlight surface is flush with the bottom surface. It can be understood that the light source 13 includes a light-emitting surface and a backlight surface. The backlight surface is disposed on the substrate 11, facilitating the arrangement of the light source 13 on the substrate 11. Moreover, since the backlight surface is flush with the bottom surface, the backlight surface can be close to the focal point of the lens 12, thereby meeting the divergence requirement of the lens 12 for the light source 13. The light-emitting surface is located inside the lens 12, facilitating the light of the light source 13 to be diverged by the lens 12, and further facilitating the illumination of the LED unit 10.

[0042] In addition, as Figure 3 shown, a groove recessed in a direction away from the substrate 11 is formed on the bottom surface, and the light source 13 is disposed in the groove. That is to say, a groove is provided on the bottom surface of the lens 12, and the groove is recessed away from the substrate 11, so that the groove can form an installation space. The light source 13 is located in the groove, facilitating the connection between the light source 13 and the substrate 11, and the groove positions the light source 13, facilitating the connection between the backlight surface of the light source 13 and the substrate 11. The light-emitting surface is diverged by the lens 12, facilitating the encapsulation among the lens 12, the light source 13, and the substrate 11, and meeting the illumination requirement of the LED unit 10. For example, the depth of the groove is the same as the thickness of the light source 13. The backlight surface of the light source 13 is connected to the substrate 11 through an adhesive such as colloid. The light-emitting surface is close to the focal point of the lens 12, facilitating the satisfaction of the illumination requirement of the LED unit 10.

[0043] Among them, as Figure 3 shown, the focal point is located at the bottom of the groove. Such an arrangement can make the light-emitting surface close to the focal point, meeting the divergence requirement of the lens 12 for the light source 13, and further facilitating the illumination requirement of the LED unit 10.

[0044] In addition, as Figure 3 shown, the light source 13 has a light-emitting surface and a backlight surface that are opposite to each other in the thickness direction of the light source 13. The light-emitting surface is connected to the groove wall, and the focal point is located inside the groove wall. It can be understood that the light source 13 includes a light-emitting surface and a backlight surface. The backlight surface is disposed on the substrate 11, and the backlight surface is flush with a part of the bottom surface surrounding the groove, facilitating the arrangement of the light source 13 on the substrate 11. The light-emitting surface is close to the groove wall, and the focal point is located inside the groove wall. Such an arrangement facilitates the arrangement of the light source 13 at the groove, facilitating the light of the light source 13 to be diverged by the lens 12, and further facilitating the illumination of the LED unit 10.

[0045] Particularly, as Figure 3 shown, the light-emitting surface is adhesively connected to the bottom of the groove. Such an arrangement can make the connection between the light source 13 and the bottom of the groove more firm, facilitating the encapsulation among the lens 12, the light source 13, and the substrate 11, and further improving the stability of the LED unit 10.

[0046] In addition, as Figures 2-4 shown, the light source 13 has a light-emitting surface away from the substrate 11, and the center of the light-emitting surface is located on the optical axis of the lens 12. That is to say, the light-emitting surface is provided on the side of the light source 13 away from the substrate 11, so that the light of the light source 13 can be diverged through the lens 12. The optical axis of the lens 12 is the axis of symmetry of the lens 12, that is, the axis of symmetry of the lens 12 is perpendicular to the bottom surface of the lens 12, and the center of the light-emitting surface is provided on the optical axis of the lens 12, so that the light source 13 can diverge a clear image through the lens 12.

[0047] In addition, as Figures 2-4 shown, the light source 13 has a light-emitting surface away from the substrate 11, and the center of the light-emitting surface deviates from the optical axis of the lens 12. It can be understood that the light-emitting surface is provided on the side of the light source 13 away from the substrate 11, so that the light of the light source 13 can be diverged through the lens 12. The optical axis of the lens 12 is the axis of symmetry of the lens 12, that is, the axis of symmetry of the lens 12 is perpendicular to the bottom surface of the lens 12, and there is a certain distance between the center of the light-emitting surface and the optical axis of the lens 12, so that the divergence angle of the light source 13 through the lens 12 can be controlled, and thus the different divergence angle requirements of the LED unit 10 can be met.

[0048] Optionally, as Figure 4 shown, the distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis is d, and d satisfies the relation: d≥0. The distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis should be within a reasonable range, that is, the distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis is greater than 0, so that there is a certain distance between the center of the light-emitting surface and the optical axis of the lens 12, so that the divergence angle of the light source 13 through the lens 12 can be controlled, and thus the different divergence angle requirements of the LED unit 10 can be met. For example, d is 1mm, 2mm or 3mm, so that it can be ensured that the light diverged by the light source 13 transmitted through the lens 12 meets the illumination requirements. When specifically designing, consider choosing a suitable parameter.

[0049] The distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis is d, and d satisfies the relationship: d ≤ 15 mm. The distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis should be within a reasonable range, that is, the distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis is less than or equal to 15 mm. If the distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis is greater than 15 mm, it will cause the light transmitted by the light source 13 to diverge at too large an angle through the lens 12, and the light efficiency will decrease, resulting in the illumination of the LED unit 10 not meeting the actual requirements, and further not meeting the illumination angle of the LED unit 10. For example, d is 12 mm, 11 mm, or 10 mm, which can ensure that the light transmitted by the light source 13 and diverged by the lens 12 meets the illumination requirements. When specifically designing, consider selecting a suitable parameter.

[0050] The distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis is d, and d satisfies the relationship: 0 ≤ d ≤ 15 mm. The distance between the center of the light-emitting surface and the optical axis in the direction perpendicular to the optical axis should be within a reasonable range. If it is within a reasonable range, the divergence angle of the light source 13 passing through the lens 12 can be controlled, and further the different divergence angle requirements of the LED unit 10 can be met. For example, d is 4 mm, 6 mm, or 8 mm, which can ensure that the light transmitted by the light source 13 and diverged by the lens 12 meets the illumination requirements. When specifically designing, consider selecting a suitable parameter.

[0051] For example, the light spot projected by a light source 13 unit at a corresponding angle is α (h, v). This light spot has a horizontal angle of h and a vertical angle of v. The teaching aid of the lens 12 in the LED unit 10 is f. The illuminance of the light spot projected by the light source 13 to a distance is E, the illuminance required by the regulations is E1, and the minimum number of light sources 13 required is m. m satisfies the relationship: m (h, v) = El / E + 1. The offset of the light source 13 at the position of α (h, v) relative to the optical axis in the lens 12 is: in the horizontal direction: Sh = f * tan (h), in the vertical direction: Sv = f * tan (v), where -35° < h < 35°, -10° < v < 10°.

[0052] According to the LED array 20 of the present invention, it includes: the LED unit 10 of the above embodiment, and multiple LED units 10 are arranged in multiple rows and columns. By setting the bottom surface of the lens 12 on the substrate 11, the lens 12 bracket can be omitted, and further the packaging steps and material costs can be saved. Moreover, the focus of the lens 12 is located on the bottom surface, and the light source 13 is arranged on the substrate 11, so that the light source 13 can be diverged through the lens 12, and further it is convenient for the LED unit 10 to perform illumination. Multiple LEDs are arranged and combined, so that an LED array 20 can be formed, and further the illumination requirements of users can be met.

[0053] Among them, as Figure 5 shown, one side surface of the substrate 11 of multiple LED units 10 facing the lens 12 is flush. It can be understood that multiple substrates 11 are arranged horizontally, so that the light sources 13 can be arranged at horizontal intervals, and the lenses 12 can be arranged at horizontal intervals, so that multiple LED units 10 can be arranged horizontally. Such an arrangement can make multiple LED units 10 emit the light of the light source 13 in the same direction, and further meet the lighting requirements of the LED array 20. For example, multiple substrates 11 can also be arranged vertically, so that multiple LED units 10 can irradiate a specific area. When making a specific design, consider choosing a suitable arrangement method.

[0054] In addition, as Figure 6 and Figure 7 shown, among multiple LED units 10 in the same row, there is an included angle between the substrates 11 of two adjacent LED units 10. That is to say, multiple LED units 10 are arranged, but there is a certain angle between two adjacent LED units 10, so that multiple LED units 10 can form an arrangement similar to an arc surface. Such an arrangement can increase the irradiation range of multiple LED units 10, and further meet the lighting requirements in different situations. For example, the included angle between the substrates 11 of two adjacent LED units 10 can be a horizontal included angle or a vertical included angle, so that multiple LED units 10 can irradiate a specific area. When making a specific design, consider choosing a suitable arrangement method.

[0055] Optionally, as Figure 6 and Figure 7 shown, there is an included angle α between the emission directions of at least two LED units 10, and α satisfies the relationship: 0°≤α≤80°. It can be understood that the included angle between the emission directions of at least two LED units 10 should be within a reasonable range. If the included angle between the emission directions of at least two LED units 10 is greater than 80°, this will cause the initial setting directions of two adjacent LED units 10 to be too large, resulting in the non-concentration of the lighting range of the LED unit 10, and further resulting in the inability to meet the lighting requirements. If the included angle between the emission directions of at least two LED units 10 is within a reasonable range, such an arrangement can make the LED unit 10 form a reasonable lighting range, so as to meet the lighting requirements, and further improve the performance of the LED unit 10. For example, the included angle between the emission directions of at least two LED units 10 is 70°, which can meet the lighting requirements in different situations and thus meet the user's usage experience. When making a specific design, consider choosing a suitable parameter.

[0056] Particularly, as Figure 6 and Figure 7 ​As shown, the light source 13 has a light-emitting surface away from the substrate 11. Among the multiple LED units 10 in the same row, the center of the light-emitting surface of the light source 13 of the LED unit 10 located in the middle region is on the optical axis of the lens 12, and the centers of the light-emitting surfaces of the light sources 13 of the LED units 10 at both ends deviate from the optical axis of the lens 12.

[0057] That is to say, the side of the light source 13 facing the substrate 11 is the backlight surface, and the side of the light source 13 away from the substrate 11 is the light-emitting surface. The multiple LED units 10 are arranged in a row. The light-emitting surface of the light source 13 in the middle LED unit 10 coincides with the optical axis of the lens 12, and the light-emitting surfaces of the light sources 13 in the LED units 10 at both ends of the row have a certain distance from the optical axis of the lens 12. Such a setting can meet the lighting requirements in different situations, thus meeting the regulatory requirements for low beam and high beam in vehicles, and further improving the safety of the vehicle. For example, three LED units 10 are arranged in a row. The light-emitting surface of the light source 13 in the middle LED unit 10 coincides with the optical axis of the lens 12, and the light-emitting surfaces of the light sources 13 in the LED units 10 at both ends have a certain distance from the optical axis of the lens 12. Four LED units 10 are arranged in a row. The light-emitting surfaces of the light sources 13 in the middle two LED units 10 coincide with the optical axis of the lens 12, and the light-emitting surfaces of the light sources 13 in the LED units 10 at both ends have a certain distance from the optical axis of the lens 12. Five LED units 10 are arranged in a row. The light-emitting surfaces of the light sources 13 in the middle three LED units 10 coincide with the optical axis of the lens 12, and the light-emitting surfaces of the light sources 13 in the LED units 10 at both ends have a certain distance from the optical axis of the lens 12.

[0058] In addition, as Figure 6 and Figure 7 shown, the light sources 13 of the LED units 10 at both ends are arranged facing the direction close to the LED unit 10 in the middle region. It can be understood that the light sources 13 of the LED units 10 at both ends are arranged close to the light source 13 of the LED unit 10 in the middle region. Such a setting can expand the irradiation range of the multiple LED units 10, thus meeting the lighting requirements in different situations, and further improving the performance of the LED units 10. For example, the multiple LED units 10 are arranged as a continuous arc surface, or a fold angle is formed between two adjacent LED units 10, so as to facilitate the expansion of the lighting range of the multiple LED units 10.

[0059] The vehicle headlamp according to the present utility model includes the LED array 20 of the above embodiment. By disposing the bottom surface of the lens 12 on the substrate 11, the lens 12 bracket can be omitted, thereby saving the packaging steps and material costs. Moreover, the focus of the lens 12 is located on the bottom surface, and the light source 13 is disposed on the substrate 11, so that the light source 13 can be emitted through the lens 12, thereby facilitating the illumination of the LED unit 10. Multiple LEDs are arranged and combined to form the LED array 20, which can meet the lighting requirements of users.

[0060] In addition, as Figure 8 and Figure 9 shown, the vehicle headlamp further includes a controller, and the controller is electrically connected to the multiple LED units 10, so as to control any one of the multiple LED units 10 to emit light. That is to say, the multiple LED units 10 are arranged at the vehicle headlamp. By changing the arrangement mode of the LED array 20, the regulatory requirements for the low beam and high beam of the vehicle headlamp can be met. Moreover, the controller is electrically connected to each LED unit 10. Such an arrangement enables the controller to control the detailed adjustments such as the angle and brightness of each LED unit 10, so as to meet the lighting requirements in different situations. For example, the LED array 20 is applied to the front vehicle headlamp or the rear vehicle headlamp.

[0061] The vehicle according to the present utility model includes the vehicle headlamp of the above embodiment. By disposing the bottom surface of the lens 12 on the substrate 11, the lens 12 bracket can be omitted, thereby saving the packaging steps and material costs. Moreover, the focus of the lens 12 is located on the bottom surface, and the light source 13 is disposed on the substrate 11, so that the light source 13 can be emitted through the lens 12, thereby facilitating the illumination of the LED unit 10. Multiple LEDs are arranged and combined to form the LED array 20, which can meet the lighting requirements of users.
