Abstract

The utility model relates to an LED (Light-Emitting Diode) lamp bulb provided with a light guide body, and the LED lamp bulb comprises a lamp body composed of a driving power supply, a cooling cavity and an LED luminous chip, wherein one end of the lamp body is connected with a lamp head. The LED lamp bulb is characterized by further comprising the light guide body, wherein the light guide body is fixedly connected with the LED luminous chip. The LED lamp bulb has the advantages that after the light guide body with functions of conducting, reflecting and scattering light is used, the irradiation angle of an LED lamp is increased, and the light is even and soft; and the LED lamp bulb is simple in structure, suitable for home and business environment and convenient in batch production.

Description

The LED bulb of band light conductor

Technical field

The utility model relates to the LED application, relates to a kind of LED bulb with light conductor in particular.

Background technology

Green light source, particularly led light source replace traditional incandescent lamp, fluorescent lamp, electricity-saving lamp, are that civilian main direction is moved towards in the LED application, the wherein the most ripe and success of the propelling of LED fluorescent lamp.Though the traditional energy-saving lamp light efficiency is high, but in a single day discarded, broken, can cause serious harm and destruction to human body and water source.And the LED illumination is prone to cause the heating irradiating angle concentrated and bulb of LED limited if adopt bulb form.At present, corn lamp and light guiding lens have solved the limited problem of irradiating angle, but in fact the corn lamp has aggravated the difficulty of heat radiation, and manufacture craft is loaded down with trivial details, is unfavorable for producing in enormous quantities; The far-end of optical material though rising angle is expanded, is difficult to accomplish on whole irradiating angle, obtain uniform light intensity with reflection from lens and refracted ray, and because the spot light characteristic of LED, can be very dazzling.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of LED bulb with light conductor is provided.

The purpose of the utility model reaches through following measure: the LED bulb of band light conductor; Comprise the lamp body that constitutes by driving power, heat radiation chamber, LED luminescence chip; One end of said lamp body is connected with lamp holder; It is characterized in that: also comprise light conductor, said light conductor is fixedly connected with the LED luminescence chip.

In technique scheme; Said light conductor adopts transparent or semitransparent material to process; The impurity structure of scattering process has been contained in translucent light conductor inside, and said light conductor inner surface has been provided with laser engraving structure, mechanical scratching structure, the frosted Processing Structure of scattering process.

In technique scheme, on said light conductor, be provided with a light inlet at least.

In technique scheme, said light conductor is a kind of in single straight tube, many straight tubes, single U type pipe, many U type pipe, cup-shaped, the approximate structures such as sphere.

In technique scheme, the other end of said lamp body is connected with the lampshade that is used to protect light conductor.

The utlity model has following advantage, through using the light conductor that light is had concurrently conduction, reflection and scattering process, the irradiating angle of LED lamp is increased, light is evenly soft, and is simple in structure, is convenient to household and business environment and uses and large batch of production.
