Abstract
The utility model discloses a light-emitting diode structure, comprising a shell, a blue light-emitting diode chip, a yellow phosphor powder layer and a lead wire which is electrically connected with the blue light-emitting diode chip, wherein the yellow phosphor powder layer and the blue light-emitting diode chip are arranged in the shell from top to bottom. The utility model is characterized in that a transparent epoxy resin layer is arranged between the yellow phosphor powder layer and the blue light-emitting diode chip. Yellow phosphor powder in the yellow phosphor powder layer is far from the blue light-emitting diode chip, and the absorption of the blue light-emitting diode chip for scattering of the yellow phosphor powder is reduced, therefore the luminous efficiency of a white LED can be obviously increased. In addition, after a layer of epoxy resin is added on the blue light-emitting diode chip, the smooth area of the coated yellow phosphor powder layer is increased, the radian of the yellow phosphor powder on the chip can be reduced, and the yellow phosphor powder layer is more uniform, so the generated light is also more uniform.

Background technology
In recent years, be used to for a long time show that the semiconductor light sources in field is LED (LightEmitting Diode), LED is the abbreviation of light emitting diode English, and just the role with the novel solid light source progressively enters lighting field.Compare energy-conservation, efficient, advantages such as volume is little, the life-span is long, response speed is fast, driving voltage is low, anti-vibration that semiconductor light sources has with conventional light source.Along with the continuous reduction of its price, the improving constantly of luminosity, semiconductor light sources has represented wide prospect in lighting field.
The core of semiconductor lighting is to utilize the semiconductor light emitting technology to realize white light.The technological approaches of realizing white light mainly contains two: the one, and red, green, blue three-primary color LED chip portfolio generates white light, and the 2nd, convert white light to by fluorescent material.Present blue-light LED chip+yellow fluorescent powder converts the white light LEDs technology to and occupies leading position.Method for this realization white light, great majority are fluorescent material and epoxy resin to be mixed directly be coated on the chip, promptly the structure that adopts usually is to comprise shell, blue LED chip, the yellow fluorescence bisque, the lead-in wire that is electrically connected with blue LED chip, the yellow fluorescence bisque is mixed by yellow fluorescent powder and epoxy resin and directly is coated in the chip curing molding and forms, owing to realize the light conversion at fluorescent coating, make the energy loss of blue light in the gold-tinted transfer process be converted into heat, therefore, the temperature of fluorescent coating is higher relatively, the temperature of led chip also increases, thereby influences the luminous efficiency of led chip.Simultaneously, the rising of temperature makes the emission wavelength drift, has influenced photochromic, in addition, because fluorescent powder and chip are close to, make the light of led chip emission and light that the led chip excitated fluorescent powder sends turn back to led chip and absorbed by led chip and lose through scattering, cause the taking-up efficient of light to reduce.
Summary of the invention
The purpose of this utility model provides a kind of light emitting diode construction, can effectively improve the luminous efficiency of white light LEDs, and the light that sends is also more even.
The purpose of this utility model is achieved through the following technical solutions.
A kind of light emitting diode construction, comprise shell, blue LED chip, yellow fluorescence bisque, the lead-in wire that is electrically connected with blue LED chip, yellow fluorescence bisque, blue LED chip are provided with from top to bottom successively and place in the shell, it is characterized in that: be provided with transparent epoxy resin layer between described yellow fluorescence bisque and the blue LED chip.
Described transparent epoxy resin layer is coated in and solidify to form a resin chip firming body on the blue LED chip, and the yellow fluorescence bisque is coated in by yellow fluorescent powder that mixes and epoxy resin and carries out curing molding on the resin chip firming body and form.
Described blue LED chip is a blue light bipolar electrode chip.
Described blue LED chip is connected with a heat carrier by substrate, and heat carrier places in the shell.
Described shell is made of plastic cement drain pan and silicon rubber cup.
The utility model compared with prior art has the following advantages:
The utility model is owing to be provided with transparent epoxy resin layer between yellow fluorescence bisque and blue LED chip, fluorescent material is away from chip like this, reduced the absorption of led chip to the fluorescent material scattering, thereby can obviously improve the luminous efficiency of white light LEDs, adding the yellow fluorescence bisque that applies after one deck resin in addition on chip increases the level and smooth area of yellow fluorescence bisque, the radian of fluorescent material on chip will reduce, the yellow fluorescence bisque can be more even, the light that comes out like this is also more even, and the fluorescent material of traditional light emitting diode construction is curved on chip, makes bright dipping inhomogeneous with regard to the thick middle both sides are thin like this.
