Description

Light emitting diode is spared the energy-conservation neon tube of light

Technical field

The utility model belongs to field of optical device technology, and particularly the Polychrome lighting lamp decoration device is specifically related to the even energy-conservation neon tube of light of a kind of light emitting diode.

Background technology

Neon tube is a kind of multi-colour luminous device, bring into play enormous function aspect environment at night, the beautifying city decorateeing, can be made into advertising lamp box with neon tube, light-emitting devices such as billboard, advertisement word, have unique advertising glamour and light decorative effect, become the symbol of city prosperity always.The body of existing neon tube is the stained glass pipe, luminescent device in the neon tube is a bulb, the main weak point of this neon tube is: the luminosity of bulb is low, power consumption is big, the driving of heat height, bulb needs high pressure, poor, the complex manufacturing technology of voltage stabilizing, fragile, service life is short.

For this reason, someone once imagined usefulness light emitting diode (LED) is that light source is made neon tube, though light emitting diode brightness height, but has the luminous effect of directed emitting characteristics and point-like, if make neon tube with light emitting diode, the light that light emitting diode sends is to disperse out along the axial direction radiation of neon tube, have only light seldom to give out from the radial direction of neon tube, whole poor visual effect, can not embody the high-grade effect of decorating, add the point-like characteristics of luminescence of light emitting diode, cause the neon tube brightness inhomogeneous, this neon tube is not attractive in appearance, so be not the luminous uniform neon tube of light source with the light emitting diode also now.

Summary of the invention

The purpose of this utility model is to address the above problem, and provides a kind of light emitting diode to spare the energy-conservation neon tube of light, it is luminous evenly, brightness is high, heating less, good visual effect, antidetonation, energy-conservation and long service life.

For achieving the above object, the utility model is by the following technical solutions:

A kind of light emitting diode is spared the energy-conservation neon tube of light, comprise crust and inner core, it is characterized in that: a plurality of light emitting diodes are housed in this inner core, each light emitting diode is arranged along the inner core axially spaced-apart, each light emitting diode connects by lead, the periphery of described inner core coats the crust that one deck is mixed with astigmatic medium, and this inner core has non-smooth outside wall surface, and sheath is equipped with in the outside of described each light emitting diode.

Bossing or sunk part are arranged on the outside wall surface of described inner core.

Described inner core is a hollow pipe, and described light emitting diode is set in the cavity of this inner core.

Described inner core is a solid tubes, and described light emitting diode is embedded in this inner core.

The material of described inner core is polyvinyl chloride or Merlon.

Be mixed with astigmatic medium in the material of described inner core.

The material of described crust is polyvinyl chloride or Merlon.

Described astigmatic medium is a kind of in titanium dioxide, barium titanate, the fluorescent material.

The material of described sheath is plastics.

The material of described inner core and crust is transparent or semitransparent material.

The utility model has following actively useful effect:

In order to overcome the directed luminous and luminous effect of point-like of light emitting diode, the utility model has installed the milky plastic sheath additional in the outside of each light emitting diode, the milky plastic sheath has played all light and astigmatic effect, weakens the luminous visual effect of point-like of light emitting diode.This inner core has non-smooth outside wall surface.Bossing or sunk part are arranged on the outside wall surface, bossing and sunk part can be point-like, ring-type, strip, screw-like etc., thereby the outside wall surface that makes inner core presents rough shape, when the light that light emitting diode sends is dispersed along the axis direction radiation, can be reflected repeatedly by near the little reflecting surface of the protruding injustice of outer core fovea superior in and reflect, make light along the axis direction transmission become to around scatter, thereby make neon tube be the lateral emitting effect.Be mixed with astigmatic medium in the outermost crust of neon tube, astigmatic medium is titanium dioxide, barium titanate, fluorescent material or pigment reflective, the astigmatism effect is arranged.The astigmatism medium has the effect of even light and diffused ray, light from the inner core ejaculation, through behind the crust, further improved the uniformity, more evenly scattering of light, form luminous visual effect continuously, so the alternative traditional neon tube of the utility model, be used for the making of various illusion-colour devices and lamp decoration.And volume is little, and pliability is good, and is energy-conservation, and long service life is installed simple and conveniently, makes the occasion except that can be used for traditional neon light, can also be used for the making of various lamp decorations, is a kind of very practical colorful light-emitting trim component.

Adopt light emitting diode to make neon tube in addition, also have following advantage:

Light emitting diode (LED) belongs to typical green illumination light source, the efficient height: can reach 80%, and its visual efficiency of the much the same incandescent lamp of light efficiency only is 10～20%.

The light quality height of light emitting diode (LED):,, do not have radiation so there is not heat owing to do not have ultraviolet ray and infrared ray in the spectrum.

Light emitting diode has the brightness height, consumes low characteristics: the power of single light emitting diode is generally at 0.05～1W, can measure body by trunking mode carries clothing ground and satisfies different needs, waste seldom, and light emitting diode adopts the principle of luminosity of three primary colours, intrinsic is colored richly endowed by nature.

The life-span of light emitting diode (LED) is long, and the standard life-span of luminous flux attenuation to 70% is 100,000 hours.

Control is flexibly: can light modulation by the high speed electric current, and different photochromic combinations can be mixed colours, and add that sequential control circuit can reach various dynamic change effect.
