Problems solved by technology

As far as the color temperature produced by the light source is concerned, the color temperature of the LED lamp bead and the coordinate values ​​of the X and Y axes of the color coordinates are usually based on the International Commission on Illumination (CIE) or Energy Star (Energy Star, ES). ), and the common LED lamp bead is used, the color temperature range of the light emitted by it is between 2600k-7000k, which has a blueish feeling, which is difficult to meet the specific requirements of warm-colored lighting required by high-end places
Therefore, the light emitted by the existing LED lamp beads has the defect of being bluish due to the high color temperature.

Embodiment Construction

[0012] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0013] The invention discloses a packaging process for LED lamp beads, such as figure 1 As shown, the LED lamp bead made by this packaging process includes a bracket 11, an LED chip 10 pasted on the bracket 11 and two pins 13, and the two electrodes of the LED chip 10 are separated by two gold wires 12. Connected to two pins 13 , the LED chip 10 is coated with a phosphor layer 14 , the phosphor layer 14 is covered with a silica gel layer 15 , and the silica gel layer 15 is covered with a plastic lens 16 .

[0014] The packaging process of the LED lamp bead includes the following steps:

[0015] A. Paste the LED chip 10 on the support 11 with insulating glue and dry it;

[0016] B, the gold wire 12 is welded between the electrode of the LED chip 10 and the pin 13;

[0017] C. Mix and stir red phosphor, green phosphor and yellow phosphor evenly....

Abstract

The invention discloses a packing technique for LED lamp beads; the technique comprises the following steps: A. LED chips are bonded on a bracket by insulation paste and are dried; B. gold threads are welded between electrodes and pins of the LED chips; C. red fluorescent powder, green fluorescent powder and yellow fluorescent powder are evenly mixed in part by weight: 20 to 25 parts of red fluorescent powder, 35 to 40 parts of green fluorescent powder and 40 to 45 parts of yellow fluorescent powder; D. 0.1 to 3 parts of rare earth raw material by weight are added in the mixed fluorescent powder materials of the step C and are evenly stirred; E. the mixed fluorescent powder materials prepared in the step D are coated on the LED chips to form fluorescent powder layers; and F. the glue injection and the formation are carried out for the LED lamp beads. According to the LED lamp beads produced by the packing technique disclosed by the invention, the light thereof can achieve the requirements of warm-color light.

Description

technical field [0001] The invention relates to the field of LED lamp bead processing, in particular to an LED lamp bead packaging process. Background technique [0002] At present, the LED series light sources sold on the market are environmentally friendly and energy-saving products that the Chinese government is promoting. They are mainly assembled from two core components, namely LED lamp beads and driving power. As far as the color temperature produced by the light source is concerned, the color temperature of LED lamp beads and the coordinate values ​​of the X and Y axes of the color coordinates are usually based on the International Commission on Illumination (CIE) or Energy Star (Energy Star, ES). ), and the common LED lamp bead is applied, the color temperature range of the light emitted by it is between 2600k-7000k, which has a blueish feeling, which is difficult to meet the specific requirements of warm-colored lighting required by high-end places . Therefore, t...
