Description
Technical field
The present invention relates to LED lamp pearl manufacture field, relate in particular to the packaging technology of a kind of LED lamp pearl.
Background technology
At present, the LED that sells on market series light source is environmental protection, the energy-saving serial product that Chinese Government is advocating use, and it mainly is assembled into by two large core components, i.e. LED lamp pearl and driving power.With regard to the colour temperature that light source produces, the coordinate figure standard of the colour temperature of LED lamp pearl and the X of chromaticity coordinates, Y diaxon is normally by (the International Commission on Illumination of Commission Internationale De L'Eclairage, CIE) or Energy Star (Energy Star, the plan of ES) formulating is implemented, and common LED lamp pearl is when using, the reference color temperature of the light that it sends is difficult to satisfy the particular requirement of the required warm colour light in high-grade place between 2600k-7000k and the partially sense of green grass or young crops is arranged.So there is the higher and partially blue or green defective of Yin Sewen in the light that existing LED lamp pearl sends.
Summary of the invention
The technical problem to be solved in the present invention is, the packaging technology of a kind of LED lamp pearl is provided, and reaches the requirement of warm colour light to make light colour temperature that LED lamp pearl sends reduce.
For solving the problems of the technologies described above, the present invention adopts following technical scheme.
The packaging technology of a kind of LED lamp pearl, it may further comprise the steps: A, led chip is pasted on the support with insulating cement and oven dry; B, gold thread is welded between the electrode and pin of led chip; C, with red fluorescent material, green fluorescence powder and yellow fluorescent material mixing and stirring, above-mentioned three kinds of materials proportioning by weight is: red fluorescent material 20-25 part, green fluorescence powder 35-40 part, yellow fluorescent material 40-45 part; D, add weight portion in the mixed fluorescent powder material of step C and be the rare earths material of 0.1-3 part and stir; E, the mixed fluorescent powder material that step D is prepared are coated on the led chip and form phosphor powder layer; F, LED lamp pearl is carried out encapsulating, moulding.
Preferably, in the described step e, the mixed fluorescent powder material is coated on the led chip by the screw point gum machine.
Preferably, described step F further comprises: G, led chip and support are fixed on the mould, pour into silica gel with the screw point gum machine in the mould and form layer of silica gel, break away from moulds behind the silica gel curing molding; H, plastic lens is covered on the layer of silica gel and compresses.
Preferably, described step e and step F are all carried out under vacuum condition.
Preferably, in the described steps A, led chip is pasted on the center of support.
In the packaging technology of LED lamp pearl disclosed by the invention, scribble phosphor powder layer at led chip, this phosphor powder layer includes red fluorescent material, green fluorescence powder and yellow fluorescent material and three mix by weight ratio afterwards, when led chip is lighted, light sees through phosphor powder layer can outwards scatter warm colour light, prove through experimental data, light sees through phosphor powder layer reference color temperature afterwards between 2000K-2600K, and the reference color temperature of existing lamp pearl is between 2600k-7000k, so the made LED lamp pearl of packaging technology of adopting the present invention to propose is because of the lower requirement that can reach warm colour light of its light colour temperature.In addition, also having added weight portion in the mixed fluorescent powder material is the rare earths material of 0.1-3 part, makes the colorimetric purity of the light that LED lamp pearl sends higher, and color is more bright-coloured.
Description of drawings
Fig. 1 is the profile of the LED lamp pearl of adopting the present invention and making.
Embodiment
Below in conjunction with drawings and Examples the present invention is done more detailed description.
The present invention discloses the packaging technology of a kind of LED lamp pearl, as shown in Figure 1, the LED lamp pearl of adopting this packaging technology to make includes a support 11, and is pasted on led chip 10 and two pins 13 on the support 11, two electrodes of led chip 10 are connected to respectively two pins 13 by two gold threads 12, scribble phosphor powder layer 14 on the led chip 10, be coated with layer of silica gel 15 on the phosphor powder layer 14, be covered with plastic lens 16 on the layer of silica gel 15.
The packaging technology of this LED lamp pearl may further comprise the steps:
A, led chip 10 usefulness insulating cements are pasted on the support 11 and oven dry;
B, gold thread 12 is welded between the electrode and pin 13 of led chip 10;
C, with red fluorescent material, green fluorescence powder and yellow fluorescent material mixing and stirring, above-mentioned three kinds of materials proportioning by weight is: red fluorescent material 20-25 part, green fluorescence powder 35-40 part, yellow fluorescent material 40-45 part;
D, add weight portion in the mixed fluorescent powder material of step C and be the rare earths material of 0.1-3 part and stir;
E, the mixed fluorescent powder material that step D is prepared are coated on the led chip 10 and form phosphor powder layer 14;
F, LED lamp pearl is carried out encapsulating, moulding.
In the packaging technology of LED lamp pearl disclosed by the invention, scribble phosphor powder layer 14 at led chip 10, this phosphor powder layer 14 includes red fluorescent material, green fluorescence powder and yellow fluorescent material and three mix by weight ratio afterwards, when led chip 10 is lighted, light sees through phosphor powder layer 14 can outwards scatter warm colour light, prove through experimental data, light sees through phosphor powder layer 14 reference color temperature afterwards between 2000K-2600K, and the reference color temperature of existing lamp pearl is between 2600k-7000k, so the made LED lamp pearl of packaging technology of adopting the present invention to propose is because of the lower requirement that can reach warm colour light of its light colour temperature.In addition, also having added weight portion in the mixed fluorescent powder material is the rare earths material of 0.1-3 part, makes the colorimetric purity of the light that LED lamp pearl sends higher, and color is more bright-coloured.
