Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of semiconductor light emitting, and specifically relates to an optical device. Background Art
[0002] Most current LED light fields are rectangular or circular. In the case of rectangular light fields, refer to Figure 3 Usually, the major axis and minor axis of the optical lens 2 are parallel to the major axis and minor axis of the bracket 1 , and the major axis and minor axis of the formed rectangular light spot 3 are also parallel to the major axis and minor axis of the bracket 1 .
[0003] Some terminal applications require the light field to rotate at a certain angle. The existing solution is to rotate the entire LED light source, that is, to rotate the entire optical lens 2 and the bracket 1 encapsulating the light-emitting chip, thereby rotating the light field, but at the same time, the LED driving circuit needs to be changed, which increases the application cost.
[0004] Based on the above, the problem to be solved at present is: to provide an optical device which can change the direction of the light spot without changing the driving circuit and has low production cost. Utility Model Content
[0005] The utility model aims to provide an optical device, aiming to solve the problems in the prior art that the light spot angle is single, the process required for adjusting the light spot angle is complex, and the production cost is high.
[0006] The utility model is implemented as follows: the optical device comprises a bracket and an optical lens arranged on the bracket;
[0007] The projections of the bracket and the optical lens on the planes where the X-axis and the Y-axis are located are respectively rectangular or elliptical or between rectangular and elliptical;
[0008] The major axis and the minor axis of the bracket are parallel to the X-axis and the Y-axis respectively, and the major axis of the optical lens forms an angle β with the major axis of the bracket, satisfying 0<β≤90.
[0009] Furthermore, a light-emitting chip is packaged between the bracket and the optical lens, and the optical axis of the light-emitting chip is arranged parallel to or overlapped with the center line of the optical lens.
[0010] Furthermore, the bracket is a tablet bracket or a bowl bracket.
[0011] Compared with the prior art, the optical device provided by the utility model has the following beneficial effects:
[0012] Prior art, see Figure 3 The long axes of the bracket 1 and the optical lens 2 are arranged parallel to each other, and the light spot generated is Figure 4, with a single direction. Figure 1 , the long axes of the bracket 1 and the optical lens 2 are set at an angle β, and the setting of different angles β can meet the needs of different application scenarios. Although the prior art can realize the rotation of the light spot by rotating the overall optical device, this setting requires synchronously changing the drive circuit, which is complex in process and high in cost. The utility model changes the direction of the light spot by rotating the optical lens 2 and the packaging method of the bracket 1 without changing the direction. This setting does not require adjustment of the drive circuit, so the manufacturing process is simple and the production cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0021] Reference Figure 1-2 As shown, it is a preferred embodiment provided by the utility model.
[0022] Reference Figure 1 The optical device includes a bracket 1 and an optical lens 2 disposed on the bracket 1. The light emitting chip is disposed on the bracket 1, and the optical lens 2 covers the light emitting chip, that is, the light emitting chip is packaged between the bracket 1 and the optical lens 2.
[0023] The projections of the bracket 1 and the optical lens 2 on the planes where the X-axis and the Y-axis are located are rectangular or elliptical or between rectangular and elliptical, that is, the planes where the X-axis and the Y-axis are located are the top-view projection planes of the bracket 1 and the optical lens 2. The major axis and the minor axis of the bracket 1 are parallel to the X-axis and the Y-axis, respectively. The major axis of the optical lens 2 forms an angle β with the major axis of the bracket 1, satisfying 0<β≤90. The angle β is adjusted according to the needs of different application scenarios to form the following: Figure 2 The light spot 3 shown has a long axis at a certain angle to the long axis of the bracket 1. The utility model changes the direction of the light field by rotating the direction of the optical lens 2, while the direction of the bracket 1 remains unchanged, and the driving circuit remains unchanged, so the manufacturing process is simple and the production cost is low.
[0024] Furthermore, the optical axis of the light emitting chip is arranged parallel to or overlaps with the center line of the optical lens 2. The bracket 1 can be arranged as a tablet bracket or a bowl and cup bracket.
