Description

LED light guide column

Technical Field

The utility model relates to a LED lighting apparatus technical field, in particular to LED leaded light post.

Background

LEDs (Light Emitting diodes) have become mainstream illumination Light sources due to their advantages of high Light Emitting efficiency, low power consumption, long service life, safety, reliability, environmental friendliness, and the like. The LED lamp tube is used as a substitute product of the fluorescent lamp tube, and has great market potential. The light guide is a structure for guiding light emitted from the LED light source from a Printed Circuit Board (PCB) to a front panel or a predetermined light emitting position.

Because the light can be refracted when entering the light thinning medium from the optically dense medium, the light can be totally reflected after the incident angle meets a certain condition. The existing light guide column is used as a lamp tube, and has the following three problems except poor mechanical property: 1) the light is not only transmitted along a straight line in the cylinder, and an outward divergent component exists in the transmission process; 2) the portions propagating along the straight line cause severe transmission at the corners; 3) also can't avoid external light to incide into the cylinder when unable preventing inside light to outside transmission, lead to leaded light post leaded light rate low, can appear scurrying the light phenomenon between adjacent leaded light post.

Disclosure of Invention

An object of the utility model is to provide a LED light guide post to prior art not enough, through selecting for use polymethyl methacrylate material and polycarbonate resin material as light guide post body material to the processing that carries out on light guide post surface, can appear scurrying the light phenomenon between the adjacent light guide post, light intensity loss is few moreover, has improved the toughness and the leaded light nature of light guide post.

In order to achieve the purpose, the utility model discloses a LED light guide post, including columniform light conductor, the inside of light conductor is cylindrical cavity structure, the light conductor has bottom surface, top surface and is located the cylinder between bottom surface and the top surface, the bottom surface is the light entering area, the top surface is the play plain noodles, it is the rough surface that has scattering power to go out the plain noodles, the internal surface of cylinder is the dull polish layer, be equipped with the reflector layer on the surface of cylinder.

Further, the light guide body is made of polymethyl methacrylate materials and polycarbonate materials.

Further, the bottom surface is provided with a light emitting diode packaging groove.

Further, the light-emitting surface is of a circular arc structure.

Further, the light reflecting layer is a nano silicon dioxide layer.

The utility model has the advantages that: (1) the light guide body is made of polymethyl methacrylate material and polycarbonate material, and has wear resistance and high strength; (2) the inner surface of the cylindrical surface is a frosted layer, and due to the fact that the surface is uneven, when light irradiates the frosted outer surface of the light guide column, a large amount of diffuse reflection can occur, the incident angle of the light is reduced when the light is refracted in the light outgoing area, and the loss of the light is reduced; (3) the nano silicon dioxide reflecting layer effectively prevents the light interference between the inside and the outside of the light guide column, and avoids the phenomenon of light interference, thereby improving the quality of light transmission of the light guide column. The utility model has the advantages of reasonable design, the principle is simple, convenient to popularize and use.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1:

the utility model provides a LED leaded light post, includes columniform light conductor 1, and the inside of light conductor 1 is cylindrical cavity structure, and the light conductor has bottom surface 11, top surface 12 and is located the cylinder 13 between bottom surface 11 and the top surface 12, and bottom surface 11 is for going into the light zone, and top surface 12 is for going out the plain noodles, and the internal surface of cylinder 13 is frosted treatment layer 130, is equipped with reflector layer 131 on the surface of cylinder 13.

The bottom surface 11 is provided with a light emitting diode package groove 110 for mounting a light source assembly.

The top surface 12 is a light-emitting surface with an arc-shaped structure, the light-emitting surface is frosted to form a rough surface with scattering capability, the light-emitting angle is increased on the light-emitting surface, incident light can be diffused, the peripheral illumination of the illuminated light is increased, the central illumination is reduced, and the uniformity of the illuminated light is increased.

The cylindrical light guide body 1 is made of a polymethyl methacrylate material and a polycarbonate resin material, and the polymethyl methacrylate material and the polycarbonate material have good light transmittance and high strength, are higher than glass in transmittance, and are light in weight and low in price. The polymethyl methacrylate material has higher hardness and wear resistance, but is brittle, and is compounded with the polycarbonate material, so that the overall toughness of the material is improved. The composite material prepared by co-extruding the polymethyl methacrylate and the polycarbonate is extruded at one time, the process is simple, and no adhesive is needed between the polymethyl methacrylate and the polycarbonate, so that the problem of residual solvent is solved, and the composite material is safe and environment-friendly. The LED light guide column is combined with the LED light guide column, the phenomena of bending and poor impact performance cannot occur, the wear resistance is good, and the practicability of the LED light guide column is improved.

The inner surface of the cylindrical surface 13 is sanded to roughen the originally smooth surface, thereby obtaining a sanded layer 130. When the light rays strike the frosted inner surface of the cylindrical surface 13, a large amount of diffuse reflection occurs, and the light rays that originally entered from the side surface are reflected and diffused by the diffuse reflection.

The outer surface of the cylindrical surface 13 is provided with a silicon dioxide reflecting layer 131 through vacuum magnetron sputtering of silicon dioxide, and a mirror surface is formed by combining a smooth surface and a reflecting coating, so that light inside the light guide column can be prevented from being transmitted out. Even if other light sources emit light to the light guide column, the light is reflected by the outer surface of the column body with the light reflecting coating, and the definition and the color purity of the LED display are guaranteed. The light-guiding properties of the light-guiding post are also improved as a large amount of light that would otherwise have been emitted from the post is directed to the correct display port.

The utility model discloses a process treatment to the leaded light post surface improves emitting diode's luminous efficiency, has effectively separated the inside and outside light of leaded light post and has scurried, avoids appearing scurring the phenomenon of light. The utility model has the advantages of reasonable design, the principle is simple, convenient to popularize and use.
