Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The preparation method of an LED light source of the present invention adopts at least one green LED chip to excite at least one red fluorescent powder to emit light. Specifically, a matching green LED chip and red phosphor powder should be selected first, such as the green LED chip and red phosphor powder shown in Table 1, and then prepared into a light-emitting element through the following steps (1) to (8). , and finally, the light-emitting element can also be prepared into an LED lamp through a simple processing method known to those skilled in the art.

[0023] (1) Expanding the film on which the green LED chip is bonded;

[0024] (2) Point adhesive glue (that is, primer or silver glue) on the LED bracket;

[0025] (3) Install the green LED chip to the position where the glue is applied;

[0026] (4) Bake the adhesive at 130-160°C for 1-2 hours...

Abstract

The invention discloses a method for manufacturing a low-color-temperature LED safety light source and an LED lamp containing the LED light source. The method for manufacturing the LED light source is achieved through an LED chip with green light and red fluorescent powder. The method comprises the steps of adopting at least one LED chip with the green light, and completing packaging through an LED packaging technology of spreading fluorescent powder glue. The LED lamp with the light source is manufactured by green light and red light, therefore, the safety light source is free of blue light and is low in color temperature, the problem of blue light overflowing or blue light enrichment is solved, and damage to the eyes of a user can not happen.

Description

technical field [0001] The invention relates to a preparation method of a low color temperature LED safety light source and an LED lamp containing the LED light source. Background technique [0002] LED light sources have the advantages of energy saving, environmental protection, rich spectrum, flexible and controllable luminous intensity, and long service life. [0003] The current white LED light sources on the market are basically realized through the packaging method of blue LED+yellow phosphor. The existence of blue LED makes the blue light components in white LED light source products far more and richer than other light quality. [0004] However, medical research has proved that blue light can cause serious damage to visual cells, and the younger you are, the more serious the damage to the human body is. Among them, since it is difficult for infants’ eye lenses to filter blue light, most of the blue light can penetrate the lens to reach the retina, and the eyes of in...
