Background technology
Lampshade has multiple effects such as the high light of blocking, protection light fixture, decoration, is used for LED fluorescent tube, handicraft outer cover, lighting decoration controlled etc. more.Traditional lampshade has only a kind of color usually, and the lighting effects of this lampshade are relatively poor, is difficult to satisfy people's needs.In addition, existing lampshade installs also cumbersome.On the other hand, although the lampshade that also has some can produce multiple color light, the production and processing difficulty is bigger, the complex structure of product, and structural strength is not high, causes easily and breaks.
For example, Chinese patent literature discloses a kind of lampshade [application number: 200520002737.3] with multiple color, in order to be installed in the bulb outside.This lampshade comprises a transparent shell, an and tail-hood that is installed in transparent shell one end, transparent shell has a hollow bulb in order to ccontaining bulb, tail-hood has a perforation that communicates with hollow bulb, it is characterized in that: lampshade comprise one be coated on the adhesion coating of transparent shell exposed face, some compartment of terrains stick to the colorful light-permeable sheet on the adhesion coating, and one sticks on the adhesion coating and in the light non-transmittable layers between the colorful light-permeable sheet in twos.The somebody has invented a kind of colorful decorative lampshade [application number: 200720179030], comprise transparent lamp shade, be positioned at least one the polychromy ring on the described transparent lamp shade, be characterized in that described polychromy ring is provided with interior discount limit, correspondingly be provided with on the outer peripheral face of described lampshade for described in the groove that buckles of discount limit, described polychromy ring buckles by discount limit in it and cooperating of described groove and encloses reliably and bind round on the outer peripheral face of described transparent lamp shade.
Though such scheme can produce the light of multiple color, structure is quite complicated, the manufacturing cost height, and structure is firm inadequately, causes easily and breaks, and is difficult to service life be protected.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, is easy to processing and manufacturing, the bicolor co-extrusion LED fluorescent tube that structural strength is high.
For achieving the above object, the utility model has adopted following technical proposal: this bicolor co-extrusion LED fluorescent tube, be arranged on the periphery of light source, comprise hollow tube body, it is characterized in that, described body surrounds two cylindrical, above-mentioned ogives by two ogives with different colours and is connected as a single entity.
Therefore two ogives in the utility model are connected as a single entity by the coextrusion mold mode, and processing is got up very conveniently, and manufacturing cost is lower.This bicolor co-extrusion LED fluorescent tube is installed in LED fluorescent tube, handicraft outer cover, lighting decoration controlled etc. when peripheral, can produces the lighting effects of different color.
The manufacture craft of this bicolor co-extrusion LED fluorescent tube is as follows: granular solid material through super-dry, is heated then, and the temperature of heating is generally 240～270 degrees centigrade, makes raw material become liquid state.By two extruders liquid material is expressed in the combination head then and carries out pre-setting.The raw material of every extruder extruding different color here.After the pre-setting, semi-finished product are entered the Vacuum shaping mould, final molding promptly gets this product again.This bicolor co-extrusion LED fluorescent tube adopts two moulds to finalize the design, i.e. head section and vacuum forming mould.The Vacuum shaping mould here has interlayer, can be used for water cooling.
In above-mentioned bicolor co-extrusion LED fluorescent tube, described inboard wall of tube body has the protruding stupefied of some even distributions and extension vertically, and above-mentioned protruding stupefied and body is connected as a single entity.
Protruding stupefied owing to being provided with at inboard wall of tube body, make the lighting effects of this bicolor co-extrusion LED fluorescent tube more attractive in appearance.In addition, protrudingly stupefiedly can effectively strengthen structural strength.
In above-mentioned bicolor co-extrusion LED fluorescent tube, described inboard wall of tube body is provided with two mounting grooves that extend vertically, and above-mentioned mounting groove is mutually opposed.
Can easily this product be installed in the periphery of light sources such as LED by mounting groove, also can take off easily.
In above-mentioned bicolor co-extrusion LED fluorescent tube, the cross section of described two ogives is semicircle, and two above-mentioned mounting grooves are separately positioned on two joint portions of two ogives.
To be the utility model by the ogive of two symmetries surround forms the pipe body, and each ogive can produce the light of different colours.The color of the ogive here can design as required.
In above-mentioned bicolor co-extrusion LED fluorescent tube, described mounting groove is separately positioned on two grooving bars on the ogive by two and constitutes, and described grooving bar extends and side by side vertically radially to projecting inward.
The grooving bar not only is used to form mounting groove, also can effectively improve the structural strength of this bicolor co-extrusion LED fluorescent tube simultaneously.
In above-mentioned bicolor co-extrusion LED fluorescent tube, described grooving bar and body are connected as a single entity.This structure is easy to processing and manufacturing, only needs man-hour to get final product by extrusion modling adding.
In above-mentioned bicolor co-extrusion LED fluorescent tube, described two ogives all adopt light-passing plastic to make.Adopt light-passing plastic can make the light transmission, avoid the luminous energy loss.
Compared with prior art, the advantage of this bicolor co-extrusion LED fluorescent tube is: 1, simple in structure, be easy to processing and manufacturing, and production cost is low.2, can make the pipe of different color as required, rich color, good looking appearance, lighting effects are good.3, can easily this product be installed in the periphery of light source by mounting groove, also can take off easily.4, protruding stupefied owing to being provided with, help the propagation of light, also improved structural strength simultaneously greatly.
