Four-pin three-core K-value-adjustable natural light-imitating LED patch

Abstract

The invention provides a four-pin three-core K value adjustable natural light imitating LED patch. The LED patch comprises a shell, an electrode foot plate, light-emitting chips, a substrate, a packaging film and a regulation and control module, the electrode foot plate, the light-emitting chips, the substrate and the packaging film are arranged in the shell, the light-emitting chips are fixed to the substrate through a conductive adhesive, a negative electrode of the light-emitting chip is connected with the substrate, a positive electrode of the light-emitting chip is connected with the electrode foot plate, the current and voltage regulation and control module is connected with the light-emitting chips through the electrode foot plate, the electrode foot plate is arranged at the bottom of the shell, the packaging film is arranged on the light-emitting chips, and the light-emitting chips comprise a low-color-temperature LED chip, a cyan LED chip and a red LED chip. The color mixing device has the advantages that the cost and the assembly space are saved, the color mixing effect is good, different spectrum, illumination and rhythm requirements are met, asynchronous and synchronous control can be realized, and the health requirements under different conditions are met.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a four-leg three-core LED patch with adjustable K value and imitation natural light. Background technique [0002] In the existing technology, in order to overcome the weakness of the valley peak light of the commonly used cold light source, lamp beads of different colors have been used to form a non-infrared imitation natural matrix light source to maintain the shortage of the spectrum of the cold light source above 680nm, and the use of lamp beads without infrared imitation The natural matrix light source was tested, and the natural light source and medium-temperature LED were used as the control group to test the influence on the eye axis of guinea pigs. As shown in Table 1, it can be seen that the use of different colors of lamp beads constitutes a non-infrared imitation natural matrix light source , keep the cold light source above 680nm low, and other parts imitate the natural light...

[0002] In the existing technology, in order to overcome the weakness of the valley peak light of the commonly used cold light source, lamp beads of different colors have been used to form a non-infrared imitation natural matrix light source to maintain the shortage of the spectrum of the cold light source above 680nm, and the use of lamp beads without infrared imitation The natural matrix light source was tested, and the natural light source and medium-temperature LED were used as the control group to test the influence on the eye axis of guinea pigs. As shown in Table 1, it can be seen that the use of different colors of lamp beads constitutes a non-infrared imitation natural matrix light source , keep the cold light source above 680nm low, and other parts imitate the natural light spectrum. Animal experiments have proved that it is effective in reducing the damage of animal myopia, but it is not feasible to produce by relying on colored lights to piece together the standard deviation and light loss.

[0003] At present, LED chips have been widely used, but at present, LED chips cannot completely form a full-spectrum matrix light source, and need to be pieced together by color lights. For this reason, it is necessary to modify the LED, change the output spectrum, remove the rich blue, and obtain the specific color. Lamp bead without infrared imitation natural matrix light source is easier to apply imitation natural continuous spectrum light source
