Abstract

The utility model provides a diode with equally lightening around, which comprises a lightening diode wafer, a transparent cover, and a junction foot, and is characterized in that: the top of the cover is a depressed body. Due to the design of the top of the cover into a structure of the depressed body, the utility model skillfully uses the photical diffusing characteristic of the depressed body, makes the light of the lightening diode wafer equally emit from the cover by polyhedral refraction of the invagination sunken, so as to make the around of the utility model luminous. The utility model is simple in structure and manufacture, the production cost is low, and the decorate effect is good. At the same time, in order to further improve the decorativeness, the cover can be designed to be a colorful object with different colors. The utility model can lighten the places around, and the structure is simple, the manufacture is easy, the production cost is low, and the decorating effect is good; therefore the utility model can be widely used in various new decorative light field.

Description

A kind of to around luminous uniform light-emitting diode

Technical field

The utility model relates to a kind of light-emitting diode, particularly a kind of to around luminous uniform light-emitting diode.

Background technology

Continuous development and the peculiar low-voltage driving of light-emitting diode itself along with the light-emitting diode chip for backlight unit technology, do not generate heat, be difficult for advantages such as fragmentation, make it more and more widely in various novel modulator Application for Field, especially the application in various decorative lamps is more remarkable. yet general its top of present known light-emitting diode is cambered outwards circular-arc cladding, the effect of optically focused is arranged because of the circular-arc cladding of evagination, therefore the light that is sent all is positive front end emission type, the light visual angle is little, and light undue concentration in the front end active zone, dazzling sensation is arranged, and the outer light intensity of active zone die-offs, the user from around the light seen very weak, influence its result of use.These shortcomings for a change, someone adopts the method for the shape change of cladding, as be designed to evagination brilliant, evagination polygonal or around cladding, design that concavo-convex point etc. is arranged, though these structures are because of interception of rays, also can see some light around it, but because its cladding end shape is always male type, therefore most light still in the past end-fire go out, light all around still a little less than, result of use is relatively poor.The patent No. is that the Chinese patent of ZL98248959 also disclosed a kind of light-emitting diode; the method of little bead is added in employing in cladding; when emission light when running into little bead because of the relation of refract light and the effect of many little beades; a part of light is emitted around diode; but because the proportion of little bead is different with the proportion of the epoxy resin of cladding; add man-hour little bead usually can skewness; cause the phenomenon of luminance nonuniformity; and manufacturing procedure is loaded down with trivial details, therefore also is difficult to be accepted by manufacturer and consumer.

Summary of the invention

The purpose of this utility model is the problem at above-mentioned existence, provide a kind of to around luminous evenly, good decorating effect, and light-emitting diode simple in structure, that making is simple and easy, production cost is low.

The technical solution of the utility model is achieved in that

A kind of to around luminous light-emitting diode, comprise LED wafer, transparent cladding, leg, be characterized in that described transparent cladding top is a sinking concave body.

The shape of the shape of described cladding and top concave volume thereof can design arbitrarily as required, cladding is a cylindrical tube as described, and its concave volume can be made as taper concave volume or semicircle concave volume, and when concave volume is the taper concave volume, for making it luminous even to all around, generally its cone angle is 100 °～160 °.

For strengthening its decorative effect, described cladding is a colored body.

The utility model is owing to adopt the cladding top to be set to the structure of sinking concave body, utilized the optics diffusion property of sinking concave body dexterously, the light that LED wafer is sent reflects and evenly emitting around cladding through the multiaspect of sinking concave body, thereby make the utility model luminous evenly all around, and it is simple in structure, making is simple and easy, production cost is low, good decorating effect, the light that has solved existing light-emitting diode effectively is that positive front end emission or most of end-fire in the past go out, all around problem such as weak, the result of use difference of light.Be further to strengthen its decorative effect simultaneously, described cladding can be made as colored body.The utility model to around luminous evenly, good decorating effect, and simple in structure, making is simple and easy, production cost is low, can be widely used in the various novel decorative lamps field.

Below in conjunction with accompanying drawing the utility model is described in further detail;

Embodiment

As Fig. 1 and shown in Figure 3, the utility model comprises LED wafer 1, leg 3, transparent cladding, for making leg 3 be difficult for from transparent cladding, deviating from, electrode suppor 31 is made on the top of described leg 3, wherein said cladding is made for adopting epoxide resin material, for the light that LED wafer 1 is sent is concentrated forward more, an above-mentioned electrode suppor 31 be provided with can ccontaining LED wafer 1 recess 311, the upper end of above-mentioned electrode suppor 31 links to each other with LED wafer 1 in another electrode suppor 31 recess 311 with a lead, as shown in Figure 4, for making it can satisfy user's needs, can be to luminous all around, and it is luminous even, strengthen decorative effect, described cladding top is made as sinking concave body, because it has utilized the optics diffusion property of sinking concave body dexterously, thereby when sinking concave body is arrived in the light direct projection that above-mentioned LED wafer 1 is sent, described sinking concave body can carry out the multiaspect refraction to light, light is evenly emitted around cladding 2, thereby make it luminous evenly all around, and light intensity is sufficient and not dazzling, the light effects uniqueness, ornamental strong.Described cladding can be difform body simultaneously, as can be the semicircle shape body; Also can be cylindric body 2.For making it easy to use, the cylindric body 2 of general employing, and the shape of described body 2 top concave volumes can design arbitrarily as required, and concave volume can be made as taper concave volume 21 as described, and described taper concave volume 21 can be coniform concave volume or the imitative polygon pyramid concave volume that bores shape; Described concave volume also can be made as semicircle concave volume.As shown in Figure 3, when described concave volume is taper concave volume 21, for better guaranteeing its result of use, its cone angle can not too greatly can not be too little, because too big or too little then LED wafer 1 direct projection of cone angle goes out light intensity deficiency around it to the then most end-fire in the past of the light on the concave volume 21, influence its result of use, learn that according to optical principle the cone angle of above-mentioned concave volume 21 is more suitable when being 100 °～160 °, wherein its cone angle best results in the time of 130 °～140 °.Be further to strengthen its decorative effect, described cladding 2 can be made the colored body of various different colours according to user's needs, and the light that the color of described cladding 2 and LED wafer 1 are sent is homochromy.As shown in Figure 3, for the user need be other colour light emitting pipe that removes blue or white the time, described light-emitting diode structure schematic diagram; As shown in Figure 5, for the user need be blue or white luminous pipe the time, described light-emitting diode structure schematic diagram.
