Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of searchlights, in particular to a vehicle-mounted external searchlight. Background Art
[0002] A searchlight is a device that has a powerful light source and a concave mirror that can focus the light in a specific direction. It is used for long-distance lighting and searching. It can use a reflector or lens to focus the emitted light beam within a very small solid angle (usually less than 2 degrees) to obtain a higher light intensity. An on-board external searchlight is generally installed at the front of the vehicle, so that it can illuminate the front of the vehicle and facilitate the driver to see the road conditions ahead.
[0003] Although the current vehicle-mounted external searchlight can achieve the purpose of lighting, it only uses a flat lens for light transmission during use, which makes the light irradiation distance short and cannot achieve long-distance and short-distance lighting, thus affecting the lighting effect. Therefore, it is necessary to design a vehicle-mounted external searchlight. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a vehicle-mounted external searchlight.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vehicle-mounted external searchlight includes a lamp holder, a lampshade is fixedly connected to the front end of the lamp holder, a lens is installed inside the lampshade, and a convex lens is fixedly connected inside the lens; a circuit board is fixedly connected to the inside of the lamp holder, an LED lamp bead is fixedly connected to the front end of the circuit board, and a reflector is installed between the lampshade and the lamp holder.
[0006] As a further description of the above technical solution:
[0007] The lens is made of a transparent acrylic plate.
[0008] As a further description of the above technical solution:
[0009] There are two convex lenses, which are symmetrically distributed on both sides of the lens.
[0010] As a further description of the above technical solution:
[0011] The rear end of the lamp holder is fixedly connected with a heat dissipation fin, and a plurality of heat dissipation fins are provided.
[0012] As a further description of the above technical solution:
[0013] Thread grooves are provided on both sides of the lamp holder.
[0014] As a further description of the above technical solution:
[0015] A threading hole is provided on the rear surface of the lamp holder, and a circular hole is provided on the front surface of the circuit board, and the circular hole corresponds to the threading hole.
[0016] As a further description of the above technical solution:
[0017] A sealing groove is formed on the front end surface of the lamp holder.
[0018] The utility model has the following beneficial effects:
[0019] Compared with the prior art, the vehicle-mounted external searchlight is provided with LED lamp beads, convex lenses and lenses. Since a plurality of LED lamp beads are provided, when performing lighting operations, long-distance lighting can be achieved under the action of the convex lens, and short-distance lighting can be achieved under the action of the lens. In this way, the searchlight can achieve long-distance and short-distance lighting at the same time, thereby improving the lighting effect. BRIEF DESCRIPTION OF THE DRAWINGS
