A kind of led chip support
Technical field
The present invention relates to a kind of led chip support.
Background technology
LED (light-emitting diode) has advantages such as cold light source, energy-saving and environmental protection, safety; Adopt the light fixture of led light source that long service life, advantage such as not fragile are arranged; And led light source do not have conventional light source to the luminous shortcoming in four sides, and the characteristics of luminescence of its high directivity can promote the light extraction efficiency of light fixture.
The encapsulation of current led light source mainly contains single and integrated two kinds of forms.The primary structure of integrated packaging LED chips support is that insulating barrier parcel electrode slice is fixed on the heating panel; The led chip of the Lights section is installed in the top of insulating barrier heating panel; Be connected with the electrode slice circuit, the silica gel that is doped with fluorescent material directly be coated in the chip top encapsulate.The led light source processed of encapsulation because the chip heating unavoidably can bring the temperature of fluorescent material to raise, has aggravated the aging of fluorescent material when work like this.
Summary of the invention
The purpose of this invention is to provide a kind of led chip support, directly be coated in the deficiency that the fluorescent material that brings the chip top is prone to aging to solve current led chip support fluorescent material.
Led chip support of the present invention comprises heating panel, electrode, insulator and phosphor powder layer; On heating panel, be provided with a led chip installation region; Pair of electrodes is embedded in the heating panel; The one of which end is exposed to the periphery of led chip installation region on the heating panel, and the other end is exposed to arbitrary edge of heating panel.Said insulator is made up of matrix and loam cake; Said matrix is fixedly connected on the one side that heating panel is provided with the led chip installation region; Loam cake is fixed on the matrix, matrix and loam cake with respect to heating panel on place, led chip installation region be provided with installing hole, phosphor powder layer is movably arranged in the installing hole.
Wherein, Loam cake with a kind of mode that is fixedly connected of matrix is: on described matrix, be provided with at least one draw-in groove; On the contact-making surface of said loam cake and matrix, be provided with the jump ring complementary with said draw-in groove, said jump ring snaps in the draw-in groove, and loam cake and matrix are connected as a single entity.
The installing hole inwall is configured to concaveconvex structure near a side of heating panel on the matrix, and when above led chip, encapsulating silica gel in the future, this concaveconvex structure can fully combine with encapsulation silica gel, has avoided the caducous deficiency of traditional led chip support packaged light source silica gel.
Led chip support of the present invention also comprises a socket, and this socket is arranged on a side of insulator, is connected with the telegraph circuit that is exposed to the heating panel edge.
Led chip support provided by the present invention is than traditional led chip support; Adopted the phosphor powder layer of independent installation; The encapsulation of fluorescent material part with led chip is separated; Not only slowed down the aging of fluorescent material greatly, and can realize the independent replacing of phosphor powder layer, to adapt to the requirement of different lamps different-colour.
The design of socket in the led chip support of the present invention has changed the technology that traditional led chip support uses welding method connection light source line, has simplified the fitting operation of led chip.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further specified.
The structure of led chip support such as Fig. 1, shown in Figure 2 comprise heating panel 1, electrode 2, insulator 3, phosphor powder layer 4 and socket 5.
The shape of heating panel 1 such as Fig. 2 are provided with a foursquare led chip installation region 11 in the central authorities of heating panel 1.Pair of electrodes 2 is like Fig. 4 arrangements; And be embedded within the heating panel 1; The one of which end is centered around the periphery of led chip installation region 11, and around led chip installation region 11, exposes a part, is used for being connected with the led chip circuit in the future; The other end of electrode 2 is positioned at one side of heating panel 1, is used for being connected with socket 5 circuit in the future.
The structure of insulator 3 such as Fig. 3 are made up of matrix 31 and loam cake 32, are respectively equipped with an installing hole 33 in the central authorities of matrix 31 and loam cake 32, and this installing hole 33 is big or small consistent with led chip installation region 11, and the position is identical.Matrix 31 is fixedly connected on the one side that heating panel 1 is provided with led chip installation region 11 through the injection moulding mode, respectively is provided with 2 draw-in grooves 34 on the both sides of matrix 31.Both sides respectively are provided with 2 jump rings 35 on the contact-making surface of loam cake 32 and matrix 31, and this jump ring 35 and draw-in groove 34 corresponding complementary snap in jump ring 35 in the draw-in groove 34, can loam cake 32 be fixed on the matrix 31, are connected as a single entity.
Phosphor powder layer 4 is to adopt fluorescent material independently to make, and it is big or small consistent with installing hole 33, can be movably arranged in the installing hole 33, in support, be placed on behind the packaging LED chips future led chip above.
Be provided with an open slot on one side of insulator 3, socket 5 is installed in the open slot.This socket 5 is connected with the terminal circuit that electrode 2 is positioned at heating panel 1 edge, is the technology of light source energising to improve tradition employing welding manner, simplifies the electrical connection operation of light source.
Can in the installing hole 33 of matrix 31, concaveconvex structure 36 be set, this concaveconvex structure 36 is set on installing hole 33 inwalls side near heating panel 1.This concaveconvex structure 36 can fully combine with the led chip encapsulation silica gel of filling in the future, prevents coming off of silica gel.
