Light guide post type lighting lamp

Abstract

The invention discloses a light guide post type lighting lamp, which is characterized by comprising a light guide post, at least one light-emitting element, and a radiator, wherein the light guide post is provided with a top face, a bottom face and a side face; the top face and the bottom face are opposite to each other; the side face is connected between the top face and the bottom face; the cross section of the light guide post is annular; a layer of reflection film is arranged on the annular inner surface; the light-emitting element is arranged on the bottom face or the top face; light emitted by the light-emitting element enters the light guide post from the bottom face or the top face, and passes through the side face by the reflection of the reflection film; the radiator is connected with the light-emitting element and is located outside the light guide post. The light guide post type lighting lamp provided by the invention not only has better heat dissipation property, and can use an LED light source with high power, but also has good light effect and beautiful appearance.

Description

Technical field [0001] The invention involves a lighting lamps, especially a light guide column lighting lamp. Background technique [0002] The traditional lighting fixtures are mainly fluorescent lamps and incandescent bulbs.As the lighting efficiency of Light Emitting Diode (LED) is continuously improved, the light emitting diode is gradually applied to the lighting lamps and applied to the lighting lamps.Compared with traditional light bulbs, light -emitting diode has absolute advantages, such as small volume, long life, low voltage / current driver, not easy to rupture, non -containing (no pollution problem), and good luminous efficiency (power saving). [0003] Lighting lamps as a pillar structure as a lighting lamps, but most of them are composed of inner lamp sources and a circular mask, which causes no heat dissipation space inside.You need to use diffusion materials, but this will cause rare light. Invention content [0004] The technical problem to be solved by the pres...

AI Technical Summary

Problems solved by technology

[0003] Lighting lamps, as a kind of lighting lamps, have many pillar structures, but most of them are composed of internal light sources and a circular mask, which leads to no internal heat dissipation space, so the power is not large, and the surface needs to be evenly illuminated. Diffusion material is required, however this results in very little light coming through
