Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lighting device that utilizes the principle of light refraction to achieve efficient light guiding. Background Technology

[0002] In scenarios requiring directional lighting, such as road lighting, tunnel lighting, and industrial equipment lighting, traditional lighting devices typically use light sources that are directly exposed or simply encapsulated, resulting in severe light dispersion, low light utilization, and unsatisfactory lighting effects. This not only wastes energy but may also cause light pollution.

[0003] In addition, traditional lighting devices have poor heat dissipation, which can easily lead to a shortened lifespan of the light source and affect the reliability and stability of the lighting device. Although some lighting devices have adopted heat dissipation measures, the heat dissipation effect is not good and cannot meet the needs of high-power lighting.

[0004] Therefore, there is a need for a lighting device that can improve light utilization, achieve directional lighting, and has good heat dissipation performance to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency light guiding and lighting device that improves light utilization through optimized structural design, achieves directional lighting, and has good heat dissipation performance, thus solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency light-guiding illumination device includes: a circular tube (1) made of a high-transmittance material, with an angled structure at its front end for guiding light downward and forward; an opaque reflective film (2) wrapped around the outer surface of the circular tube (1) for reflecting light back into the circular tube and reducing light loss; a light-emitting lamp (3) disposed at the rear end of the circular tube (1) for providing a light source; an integrated circuit board (4) electrically connected to the light-emitting lamp (3) for controlling the operation of the light-emitting lamp; and a heat dissipation device (5) connected to the integrated circuit board (4) for dissipating the heat generated when the device is working.

[0007] Preferably, the high-transmittance material is one of quartz glass, acrylic or PC material, which has good light transmission performance and mechanical strength.

[0008] Preferably, the opaque reflective film is one of aluminum foil, silver-plated film, or highly reflective coating, with a reflectivity of up to 90% or more, which can effectively reduce light loss.

[0009] Preferably, the bevel angle at the front end of the circular tube is 30°-60°, and through optical design, it can efficiently guide light downwards and forwards to achieve directional illumination.

[0010] Preferably, the light source is an LED lamp bead, with a quantity of 1-10, evenly arranged at the rear end of the circular tube, which has the advantages of low energy consumption and long life.

[0011] Preferably, the heat dissipation device is one of an air-cooled heat sink, a liquid-cooled heat dissipation system, or a heat pipe heat dissipation device, which can effectively dissipate the heat generated during the operation of the device and extend the life of the light source.

[0012] Preferably, the integrated circuit board is provided with a brightness adjustment module, which is used to adjust the brightness of the lamp according to actual needs and improve energy utilization.

[0013] Preferably, the rear end of the circular tube is provided with a sealing cap to fix the light source and the integrated circuit board, while preventing dust and moisture from entering and improving the reliability of the device.

[0014] The high-efficiency light-guiding illumination device of this invention has the following beneficial effects: 1. High light utilization rate: By combining a high-transmittance circular tube with an opaque reflective film, the scattering and loss of light are reduced, thereby improving the light utilization rate.
