Problems solved by technology

[0003] However, for 5050RGB ordinary models, the brightness and darkness of a single R, G, and B light are greatly different during the lighting process, resulting in a large difference in perception; at the same time, B light has risks such as blue light exposure.

Embodiment 1

[0026] Such as Figure 1-2 As shown, the implementation method of making the lamp beads emit soft light and controlling the red shift of blue light described in the embodiment of the present invention mainly consists of the following steps:

[0027] (1) At first, install the blue light chip 3 and the green light chip 5 respectively on both sides of the built-in chip of the SMD support body 1 with the support pin 2, and increase the red light chip 4 between these two chips;

[0028] (2) Then, a layer of silicone resin layer 6 is uniformly filled inside the frame body of the wafer and the silicone resin layer 6 is completely covered on the outer surfaces of these wafers;

[0029] (3) Green powder equivalent to 0.2% by weight of the silicone resin is added inside the silicone resin layer 6 to make the luminescence softer and reduce the risk of blue light damage.

Embodiment 2

[0031] Such as Figure 1-2 As shown, the implementation method of making the lamp beads emit soft light and controlling the red shift of blue light described in the embodiment of the present invention mainly consists of the following steps:

[0032] (1) First of all, the chip is first built into the support body, and the blue light chip 3 and the green light chip 5 are respectively installed on both sides of the chip of the SMD support body 1 with the support pin 2, and the red light is added between the two chips chip 4;

[0033] The lines connecting the respective center points of the red light chip 4, the blue light chip 3 and the green light chip 5 form an isosceles triangle area; the lines connecting the respective center points of the blue light chip 3 and the green light chip 5 form the base of an isosceles triangle;

[0034] (2) Then, a layer of silicone resin layer 6 is uniformly filled inside the frame body of the wafer and the silicone resin layer 6 is completely c...

Embodiment 3

[0037] Such as Figure 1-2 As shown, the implementation method of making the lamp beads emit light softly and controlling the red shift of blue light described in the embodiment of the present invention also includes that each of the blue light chip 3 and the green light chip 5 has an access terminal and a lead terminal, where the built-in chip is located. There is a chip slot inside the SMD support body 1, and an adhesive layer is arranged between the silicone resin and the edge of the top surface of the support body.

Abstract

The invention relates to an implementation method which enables emergent light of a lamp bead to be soft and controls red shit of blue light. The implementation method comprises the following steps: mounting a blue wafer, a green wafer and a red wafer in an SMD support body provided with support pins; uniformly filling the interior of the support body mounted with the wafers with a silica gel resin layer; and adding 0.2% of green powder into the interior of the silica gel resin. The implementation method provided by the invention has the beneficial effects that 0.2% of green fluorescent powder is added, so that emergent light is soft, perception is softer, and the problem that perception difference is big as light intensity difference is big is solved; and the red shit of the blue wafer can be controlled by adding the green powder, and injury risk is reduced.

Description

technical field [0001] The present invention relates to 5050RGB lamp bead technology, in particular to a realization method for softly emitting light from lamp beads and controlling the red shift of blue light, which is used in fields such as toy products and SMD LED projection products. Background technique [0002] 5050RGB lamp bead is a kind of LED lamp bead. It is named after the product size. It refers to the three primary colors of red light, green light and blue light. The main features of the lamp bead are: low voltage drive, environmental protection and energy saving; small size, easy installation; high brightness , the scattering angle is large, and the consistency is good. Therefore, 5050RGB lamp beads can be mainly used for LED flexible light strips, LED hard light strips, LED modules, LED backlights, etc. [0003] However, for the common 5050RGB model, the brightness and darkness of a single R, G, and B light differ greatly during the light-emitting process, re...
