Shipboard high-power light emitting diode (LED) searchlight

Abstract

The invention discloses a shipboard high-power light emitting diode (LED) searchlight comprising a high-power LED packaging module, a circular bottom plate, a parabolic light-gathering cup, and a free curve lens. The shipboard high-power LED searchlight is characterized in that the bottom part of the parabolic light-gathering cup is provided with a long-strip-shaped connecting plate, the parabolic light-gathering cup is installed on the circular bottom plate through a screw; the center of the circular bottom plate is provided with a center hole; the lower surface of the circular bottom plate taking a center hole as the center of a circle is provided with an upper concave circular groove, the high-power LED packaging module is buckled in the upper concave circular groove on the lower surface of the circular bottom plate; the upper surface of the circular bottom plate is provided with a lower concave circular groove, and the bottom part of the free curve lens is provided with an annular convex ring; and the convex ring is embedded in the lower concave circular groove. The shipboard high-power light emitting diode searchlight has the advantages that by adopting the optical design method of the combination of the light-gathering cup and the free curve lens, the LED light ray is collimated, the light rays of all the angles of high-power LEDs can be effectively controlled; the problems of oversized and overweight lamp as well as low efficiency for light utilization rate are avoided; the characteristics of lighting of the shipboard searchlight is achieved.

Description

technical field [0001] The invention relates to an LED light source, in particular to a ship-mounted high-power LED searchlight. Background technique [0002] High-power LED lighting components generally require two optical designs before they become lighting products. One-time optical design to solve the range and distribution of LED light angle, light intensity, luminous flux, light intensity distribution, and color temperature. The secondary optical design needs to refract or reflect the light after passing through the primary lens to meet the lighting requirements of various occasions. For search and rescue LED searchlights, the current secondary optical design idea is to collimate the light emitted by the LED. Commonly used forms include curved surface focusing cups (including paraboloids, spheres, ellipsoids, and hyperboloids) and free-form lenses. However, using a spotting cup or a free-form surface lens alone will cause the disadvantages of too large, too heavy, o...

Problems solved by technology

However, using a spotting cup or a free-form surface lens alone will cause the disadvantages of too large, too heavy, or low light energy utilization, which will cause inconvenience in use or increase manufacturing costs.

The condenser cup cannot control the small-angle light emitted by the LED, while the free-form surface lens has poor control ability for large-angle light and there is material absorption
