All-period-luminosity LED lamp with LED inverted wafer

Abstract

The invention discloses an all-period-luminosity LED lamp with an LED inverted wafer. The all-period-luminosity LED lamp comprises a light source, wherein the light source comprises a substrate and the LED inverted wafer, and the LED inverted wafer is mounted on the upper side of the substrate; the substrate is a transparent substrate, and the circumferential surface of the LED inverted wafer is coated with a fluorescent glue layer; a light reflecting structure is arranged on the surface of the fluorescent glue layer on an LED wafer, and the area of the light reflecting structure is 1 / 2 of that of the fluorescent glue layer; and a circuit layer is arranged on the upper surface of the substrate, an electric connecting point of the LED wafer is arranged on the circuit layer, and the LED inverted wafer is connected with the electric connecting point of the LED wafer on the substrate. According to the all-period-luminosity LED lamp, a dark region is compensated by a lighting part through reflected light of the light reflecting structure, and finally the luminosity of the whole lamp is uniform.

[0003] Patent No. CN204189826U patent document, patent No. CN204315628U patent document and patent No. CN204315621U patent document disclose LED light source flip-chip technology; The problem of low success rate; however, the current LED light source flip-chip technology is mainly used on metal substrates such as aluminum and copper or on ceramic substrates. Due to the influence of the light transmittance of the substrate, the light angle of the light source module is also limited, so it cannot be done. The light spot is consistent up to 360 degrees; and because the LED flip chip itself only emits light from five sides, the side with electrodes is affected by the electrode and insulating layer and the light effect cannot be emitted, which also makes the chip substrate unable to achieve a 360-degree full-circle light spot unanimous
