Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floodlights, in particular to an LED floodlight arranged in an equilateral triangle and emitting light uniformly. Background Art
[0002] LED floodlights are widely used lamps that use LED lamp beads to emit light. To ensure the brightness of the lighting, LED floodlights are generally equipped with a large number of LED lamp beads. Most of the LED lamp beads on the market are arranged in squares or rectangles. The overlap between the diffused light spots of the lamp beads arranged in this way is relatively small, and the gap is large, which will lead to greater light loss in actual use and poor uniformity of light irradiation.
[0003] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, a LED floodlight with uniform light emission in an equilateral triangle arrangement is provided to solve the technical problems of large light loss and poor uniformity of light irradiation of current LED floodlights. Utility Model Content
[0004] The utility model aims to provide an LED floodlight arranged in an equilateral triangle and emitting light uniformly, so as to solve the technical problems of large light loss and poor uniformity of illumination of existing LED floodlights.
[0005] The technical solution of the utility model is achieved in this way:
[0006] An LED floodlight with uniform light emission arranged in an equilateral triangle comprises a shell and a bracket, wherein the shell and the bracket are rotatably connected, an LED lamp board is arranged in the shell, a plurality of uniformly distributed LED lamp beads are arranged on the LED lamp board, three adjacent LED lamp beads are arranged in an equilateral triangle, and lenses matching the LED lamp beads are arranged on the outer side of the LED lamp beads.
[0007] As a preferred embodiment, the LED lamp beads on the LED lamp board are arranged in three rows, the adjacent LED lamp beads in each row are spaced the same, the three rows of lamp beads are arranged in parallel, and the middle row of lamp beads is staggered with the lamp beads on both sides.
[0008] As a preferred implementation, the top surface of the shell is inclined.
[0009] The beneficial effects of the utility model are:
[0010] The utility model uses the unique design of equilateral triangle arrangement of LED lamp beads to maximize the overlap between the diffuse light spots formed by the LED lamp beads, and can reduce the spacing between adjacent LED lamp beads in the surrounding area. The smaller the spacing, the smaller the light loss. The smaller the gap, the more LED bright spots will appear, making the light brightness greater. The design of equilateral triangle arrangement evenly distributes the light points and dark areas, making the light emission more uniform, which solves the technical problems of large light loss and poor uniformity of light irradiation in existing LED floodlights.
