Abstract

The utility model discloses a novel light guide column. The light guide column comprises a column body; a V-shaped column block is arranged at the top of the column body; an arc-shaped block is arranged in an indentation in the bottom of the column body; the side surface of the column body is a surface formed by free curves or continuous cross-sections, a Fresnel lens surface, a continuous free curved surface or a special-shaped array; the column block comprises a top surface and an oblique side surface; the oblique curved surface is formed by a straight-line surface, a free curved surface or continuous cross-sections or is a plane; the top surface is a sphere or an aspherical array, namely multiple array modes are provided, including longitudinal, transverse and crossed array modes, and in addition, the top surface is smooth or frosted; and the arc-shaped block is positive conical or inverted conical, and is formed by conical side surface free curves or free curves, continuous cross-sections, a Fresnel lens surface, a continuous free curved surface or a special-shaped array. The novel light guide column not only has grace appearance, good heat radiation effect and small area, but also can ensure uniform distribution of LED light, and is simple in structure, convenient and practical.

Description

The novel optic post

Technical field

The utility model relates to the LED lamp device, is specifically related to the light-guiding pillar of a kind of LED.

Background technology

Because the development of LED industry is rapid, the LED light fixture progressively replaces traditional lighting; But the bulb lamp in the LED lighting does not reach the effect of traditional bulb lamp all the time.It is mainly manifested in: 1, and traditional bulb lamp angle has 120-340 degree .2, the characteristics that light is evenly distributed. and the LED bulb lamp tool situation on the present market is:

1), maximum 150 degree of bulb lamp angle;

2) if surpass the light fixture of 150 degree, moulding is ugly, and heat radiation is difficult to resolve determines, and area is large;

3) if the angle that satisfies, moulding, heat radiation, area for cutting. and the distribution of light inequality very.

For this reason, we have researched and developed a novel light-guiding pillar, can solve an above difficult problem.

The utility model content

The utility model addresses the above problem and provides that a kind of light is evenly distributed, outward appearance is graceful, the light-guiding pillar of good heat dissipation.

For addressing the above problem, the utility model is realized by following scheme: the novel optic post, it comprises cylinder, recess is provided with the arc piece in the post piece of this cylinder top setting " V " type, the bottom, the side of described cylinder is the face that free curve consists of, or continuous tangent plane formation, or continuous free form surface.

Described post piece is divided into end face and prism, and described prism is that planarea consists of, or the free curved-surface formation, or continuous tangent plane consists of.

Described end face is light face or frosting.

Described arc piece is regular conical or turbination, is made of the tapered side free curve.

Described arc piece is that continuous tangent plane consists of, or continuous free form surface.

Advantage of the present utility model: not only moulding outward appearance is graceful, good heat dissipation effect, and area is little, can also guarantee being evenly distributed of LED light, and it is simple in structure, convenient and practical.
