Problems solved by technology

[0003] People apply green LED lamp beads in the environment to increase the green light effect in the scene and make people feel closer to nature. However, the phosphor formula of traditional LED lamp beads is simple, so that the luminescence of traditional LED lamp beads Low color temperature, LED lamp beads with low color temperature often make the scene color lack authenticity and affect people's visual perception. Therefore, we need to improve the production process of LED lamp beads

Embodiment Construction

[0020] Such as figure 1 As shown, the manufacturing process of the LED lamp bead of the present invention includes the following steps: a. Fix the LED chip on the LED bracket by using a crystal-bonding glue and perform baking treatment; b. Use the positive and negative poles on the LED chip and the electrodes of the LED bracket to Weld the gold wires together; c. Mix and stir the fluorescent powder, glue A, and glue B in proportion; d. Fill and coat the mixed phosphor, glue A, and glue B on the LED bracket and cover the LED chip; e. Fill and coat The LED bracket with fluorescent powder, glue A and glue B is baked and formed.

[0021] The present invention includes the following improvements: the fluorescent powder includes yellow-green powder with a fluorescent wavelength range of 295-305nm, and green powder with a fluorescent wavelength range of 530-540nm. The fluorescent powder in this embodiment adopts yellow-green powder with a fluorescent wavelength range of 302nm, Green...

Abstract

The invention discloses a high color temperature LED lamp bead manufacturing process. The raw materials include LED brackets, LED chips, fluorescent powder, A glue, B glue, and crystal-bonding glue. The LED chip is fixed on the LED bracket through the crystal-bonding glue. The LED chip is sealed with a mixture of fluorescent powder, glue A, and glue B. The phosphor includes yellow-green powder with a fluorescent wavelength range of 302nm, and green powder with a fluorescent wavelength range of 537nm. The yellow-green powder, green powder, glue A, and glue B The color matching ratio is 1.6:0.63:13:26. This process can improve the green color temperature of the LED light, making the green color of the LED light closer to the green color of the leaves, increasing the realism of the scene where this LED light is applied, and making people's visual experience more vivid. Rich, improve people's visual experience.

Description

technical field [0001] The invention relates to a manufacturing process of an LED lamp, in particular to a manufacturing process of an LED lamp bead with a high color temperature. Background technique [0002] With the development of modern society, LED technology is widely used, and with the improvement of people's living standards, the requirements for the color temperature effect of LED lamp beads have also been raised to another level. [0003] People apply green LED lamp beads in the environment to increase the green light effect in the scene and make people feel closer to nature. However, the phosphor formula of traditional LED lamp beads is simple, so that the luminescence of traditional LED lamp beads Low color temperature, LED lamp beads with low color temperature often make the scene color lack authenticity and affect people's visual perception. Therefore, we need to improve the manufacturing process of LED lamp beads. Contents of the invention [0004] In order...
