Abstract

The invention discloses a light-emitting diode (LED) chip bracket, which comprises a heat sink, electrodes, an insulator and a fluorescent powder layer, wherein the insulator consists of a substrate and an upper cover; the substrate is fixedly connected to the heat sink; the upper cover is fixed on the substrate; mounting holes are formed on the substrate and the upper cover; and the fluorescent powder layer is movably arranged in the mounting holes. In the LED chip bracket provided by the invention, the fluorescent powder layer is independently arranged and separated from the encapsulation of an LED chip, so the ageing of fluorescent powder is greatly slowed down, and the fluorescent powder layer can be independently replaced so that requirements of different lamps and lanterns on different color temperatures can be met.

Description

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.
