Description

A kind of LED of optically focused again lamp

Technical field

The utility model relates to lighting technical field, relates to a kind of LED of optically focused again lamp in particular.

Background technology

LED is the abbreviation of English light emitting diode (light emitting diode); Its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing then all around; Play the effect of protection internal core, so the anti-seismic performance of LED is good.In room lighting, because LED lamp source size is less, luminous flux is higher again, causes the LED surface brightness higher, and general high-high brightness surpasses 300000cd/m ², and the adaptable brightness of human eye is 7000-8000cd/m ², i.e. this brightness can be satisfied the requirement of human eye to dazzle, therefore, need the dazzle of LED lamp effectively be limited to a great extent.Like one Chinese patent application number is CN200910190797.5, and denomination of invention is a kind of LED anti-dazzle lamp, comprises the led light source with lens, the concavees lens that coat lens of said led light source, and it is used for the emergent light of led light source is carried out the floodlight first time; And the anti-dazzle transparent member that is provided with lens junior unit array that coats said concavees lens, it is used for the light behind the concavees lens floodlight is carried out the floodlight second time.The LED anti-dazzle lamp of this patent structure can effectively reduce the brightness of lamp surface, and its shortcoming is: 1, the area of anti-dazzle transparent member is bigger, generally can only be installed on the light fixture, and to having relatively high expectations of installing space, mounting or dismounting are inconvenient; 2, the LED anti-dazzle lamp has adopted concave mirror principle astigmatism, does not use convex lens optically focused and is used for constituting the virtual image of LED lamp pearl, does not reach the illumination effect that the more lamp pearls of magically change come once more diffused light source and make up multiple style.3, the LED anti-dazzle lamp is the same with all common LED lamps, and its light that sends can only be to positive outgoing, and the back side of LED lamp does not have emergent ray, is difficult to be applied in the occasion that decorative effect is had relatively high expectations.

Summary of the invention

The purpose of the utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy for installation, and the wider LED of the optically focused again lamp of range of application.

The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of LED of optically focused again lamp; The shell of led light source, encapsulated LED light source and the substrate that comprises lamp holder, substrate and upward be provided with; It is characterized in that; Said case surface is provided with light conductor, and light conductor is provided with plural prefocus cup.

As further specifying of such scheme: said light conductor is multiple shape, and is tapered like integral body, or whole globulate or multiform shape more, and the bottom outer rim of light conductor stretches out, and conveniently is connected with case surface.

Said light conductor is one or more stacks.

Said light conductor adopts multilayer boss overlaying structure, and between adjacent two boss, the base area of first floor boss is less than the top surface area of secondary boss in the multilayer boss, and every layer of light conductor top is provided with the caustic surface of being furnished with prefocus cup respectively.

Said each prefocus cup is that the bottom of cup-shaped counterbore is provided with cambered surface to light conductor bottom surface direction or the recessed cup-shaped counterbore of side surface direction, can with led light source again optically focused constitute the virtual image of LED lamp pearl and come diffused light source once more.

The shell integral body of said encapsulated LED light source and substrate is horn-like, and the arranged outside of the corresponding led light source of shell has the refraction inclined-plane, can be with led light source to the light refraction of the side direction outgoing back side to substrate.Refraction also can be provided with prefocus cup on the inclined-plane, can be with the light again optically focused formation LED lamp pearl virtual image of led light source to the side direction outgoing, and diffused light source shines the back side of substrate once more, and the range of tilt angles on refraction inclined-plane is the 0-80 degree.

Said lamp holder is provided with outer bubble, and outer bubble is placed in outside led light source, shell and the light conductor, and shell is the epoxy resin layer of global formation or the encapsulating structure of being made up of the upper and lower shell of mutual clamping.

The shell of said encapsulated LED light source and substrate is the long strip type encapsulating structure that light trough and transparent lower casing are formed, cross-sectional outer semicircular in shape or other shape; The arranged outside of the corresponding led light source of shell has the refraction inclined-plane, can be with led light source to the light refraction of the side direction outgoing back side to substrate.

Said substrate is the strip thin plate, and light conductor with matching then is strip shape body, cross section semicircular in shape or other shape.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:

1, the utility model is employed on the shell of LED lamp prefocus cup is set, and has convex lens character, and outside more luminous diffused light source after the LED light that can will disperse converges can effectively solve existing indoor LED lamp on the one hand and produce the problem of dazzle; On the other hand, need not the anti-dazzle function that anti-dazzle light fixture also can normally be brought into play the LED lamp, thereby can not influence the brightness and the definition of light source, more more reasonable than known glare prevention structure design.

2, through a plurality of prefocus cups, the LED light that can will disperse converges and forms the virtual image of LED lamp pearl, and by the various distributions of a plurality of prefocus cups, the virtual image of LED lamp pearl also is combined into multiple style, is very much that magically change is attractive in appearance.

3, the arranged outside of corresponding led light source refraction inclined-plane on shell can just can satisfy higher decorative light photograph effect requirements with simple structure with led light source to the light refraction of the side direction outgoing back side to substrate.
