Abstract

The utility model relates to a directional light high-efficiency LED which comprises an LED electrode support, an LED chip, a lens and a transparent epoxy resin packing body, wherein the lens is a convergent lens which provided with a plurality of optical surfaces and is also called a Fresnel lens, a bowl-shaped reflection cavity is connected with the LED electrode support, the LED chip is positioned in the bowl-shaped reflection cavity and lies in the focal point F of the Fresnel lens, and the elements are sealed into a whole by the epoxy resin packing body. The utility model has the advantages of simple structure and convenient manufacture. The structure of an ordinary LED needs not to be changed largely. The utility model has good light condensation effect and favorable light orientation performance. The ejected light is close to the parallel light, and the intensity of the directional light output is much higher than the ordinary LED.

Description

The directional light efficient LED
The utility model relates to the improvement of a kind of light-emitting diode (being LED), the particularly a kind of directional light light-emitting diode that can export high light intensity.
Develop rapidly along with contemporary science and technology, the continuous appearance of various new technique new materials, people are that the application study of LED has obtained significant progress to light-emitting diode, because LED has long service life, can reach 100,000 hours, the technical characteristic of various excellences such as the little power consumption of low-voltage, safety and reliability height, luminescence response speed are fast makes LED that the trend that substitutes traditional luminescent device be arranged greatly as a kind of new type light source.In order to enlarge the range of application of LED, accelerate to replace the paces of traditional luminescent device, the collection that must manage to improve as much as possible the led chip luminous energy utilizes effect, to overcome the inferior position of the obvious deficiency that the LED luminous intensity exists with respect to traditional luminescent device.And the various light-emitting diodes that are being developed at present use to the luminous energy collection form of chip nothing more than being the principle of utilizing general convex lens optically focused, promptly normally led chip being placed the top is hemispheric transparent epoxy resin packaging body, make light-emitting diode by different led chip package position with different scattering angles, there is the directional collecting weak effect of light in the light-emitting diode of this traditional form, light scatters greatly, causes the light effective energy to utilize defectives such as low.
The purpose of this utility model is exactly a kind of new light-emitting diode that designs for the many disadvantages that solves above-mentioned led light source.
Formation of the present utility model mainly comprises the LED electrode suppor, led chip, lens and transparent epoxy resin packaging body, it is characterized in that described lens are to have the convergent lens (claiming Fresnel Lenses again) that a plurality of optical surfaces are formed, one bowl-shape reflector cavity is connected in that led chip places bowl-shape reflector cavity on the LED electrode suppor, and be in the focal point F place of Fresnel Lenses, by regulating the displacement between led chip and the lens focus F, obtain the directional light output of different angle of scatterings, be packaged into one and location through transparent epoxy resin packaging body again.
The utility model has following accompanying drawing
Fig. 1 is the utility model optical principle structural representation;
Fig. 2 is the right view of the utility model structure;
Fig. 3 be the utility model embodiment two become the planar light system of battle formations of approximate circle hexangle type shape by a plurality of six rib monomer LED permutation and combination;
Fig. 4 is the plate LED monomer figure that three the employing four footnote collimator electrode supports encapsulation of the utility model embodiment forms.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Embodiment one:
Referring to Fig. 1,1 is connected with a bowl-shape reflector cavity 2 on it for the LED electrode suppor among the figure, this reflector cavity 2 is the spheric reflection pit that goes within the light reflected back optically focused cornerite of direction beyond the led chip institute directive lens light gathering wrap angle sigma and be provided with, 3 is led chip, this chip 3 can be a single-chip, also can be multicore sheet monochrome or multicore sheet colour mixture, 4 is Fresnel Lenses for having the convergent lens that a plurality of optical surfaces form, F is the focus of Fresnel Lenses, 5 is LED transparent epoxy resin packaging body, led chip 3 places bowl-shape reflector cavity 2, and the focal point F place that is in Fresnel Lenses 4 exports the displacement that requires to regulate between led chip and the lens focus F according to the directional light of different angle of scatterings, also locate with being packaged into a cylinder through transparent epoxy resin packaging body again, thereby formed a kind of directional light efficient LED that top encapsulation is become the Fresnel Lenses shape of the present utility model.
Embodiment two:
Referring to Fig. 1, Fig. 2.Identical with embodiment one structure, different is that package implementation is shaped as multiple edge body shape, and the light-emitting diode permutation and combination of a plurality of the utility model structures can be become the planar light battle array of definite shape.Can also adopt multiple permutation and combination method to obtain the luminous light battle array of planar LED of various different size shapes, the planar light battle array of different shape can be mixed the light-distribution lens of shades of colour and Specialty Design making again, can make the led light source signal modulator of various uses.
Embodiment three;
Referring to Fig. 4, identical with embodiment one, different is to have adopted four footnote collimator electrode supports, has shown the applicability of the utility model to the different LED electrode suppor, to satisfy different product design characteristics needs.
The utility model has the advantages that the convergent lens of LED top is that Fresnel is saturating Mirror can be designed to that led chip is had maximum convergence of rays and collect cornerite, adds electricity Bowl-shape reflector is to irradiant reflex on other direction of chip on the utmost point support, so that The directional light output intensity of this LED is greatly improved, and its ejaculation light almost connects Near is no scattering directional light, produces for forming different purposes signal modulators after having made things convenient for widely Product and the light-distribution lens design work carried out. And the utility model is than common LED light The source body has simple in structurely, easily manufactured equally, does not need common light emitting diode Structure do big change, not only be suitable for conventional LED automatic machine processing request, all right Adopt the LED Encapsulation Moulds row culture secondary epoxy of customization to be cast into common finished product of LED Type.
