Problems solved by technology

Pentaluminescent CSP products have high luminous efficiency, less light loss, and a near-field luminous angle close to 180°, which is suitable for the field of lighting; however, in the field of backlight, it is difficult to design a lens for five-sided CSP, and the blue leakage at the bottom of the five-sided CSP affects the backlight Effect
At present, single-side...

Embodiment Construction

[0036] The present invention will be further explained below in conjunction with the drawings.

[0037] See as figure 1 As shown, the light-enhancing single-side light-emitting CSP LED described in this specific embodiment is characterized in that it includes a white wall glue 1, an LED chip 2, a packaging glue 3; the white wall glue 1 is in the shape of a bowl , The bottom of which is hollowed out, the LED chip 2 is arranged inside the white wall glue 1, and the electrode surface 2-1 at the bottom of the LED chip 2 is flush with the bottom of the white wall glue 1, and the periphery of the LED chip 2 and the white wall glue The bowl of 1 is filled with encapsulating gel 3.

[0038] Further, the packaging glue 3 is a mixture of phosphor powder and packaging glue.

[0039] Further, the white wall glue 1 is a square bowl-shaped white wall glue, the outer size of which is the size of the CSP LED, and the material is epoxy glue or silicone glue.

[0040] The processing method of the ligh...

Abstract

The invention relates to a light-reinforcing single-sided light emitting type CSP LED and a processing method thereof, and relates to the technical field of LEDs. The light-reinforcing single-sided light emitting type CSP LED comprises a white wall adhesive, an LED chip and a packaging colloid, wherein the white wall adhesive is in the shape of a bowl cup with the bottom being hollowed out, the LED chip is arranged inside the white wall adhesive, an electrode surface at the bottom of the LED chip is flush with the bottom of the white wall adhesive, the periphery of the LED chip and the bowl cup of the white wall adhesive are filled with the packaging colloid. The extraction of white light is greatly improved, the light is more concentrated and uniform after diffuse reflection, the lens matching is more convenient in the field of backlight, and the practicability is higher.

Description

Technical field [0001] The present invention relates to the technical field of LEDs, in particular to a light-enhancing single-side light-emitting CSP LED and a processing method thereof. Background technique [0002] As a simple LED package product, CSP LED is widely used in lighting because of its advantages of no substrate, no bonding wire, small size, light thickness, high power load, and strong size design flexibility. , Backlight, automotive and other fields. [0003] The appearance of CSP LED has also developed different structures and morphological characteristics following the needs of the application. The original CSP developed from the traditional single-side light-emitting PLCC and QFN package form to the five-side light-emitting CSP. The five-sided luminous CSP product has high luminous efficiency and low light loss, and the near-field luminous angle is close to 180°, which is suitable for the lighting field. However, in the backlight field, it is difficult to design...
