Efficient intelligent LED light source

Abstract

The invention discloses an efficient intelligent LED light source which comprises a package substrate and a chip unit arranged on the package substrate. The chip unit is divided into at least one naked type chip unit body and at least one wrapped type chip unit body, wherein the wrapped type chip unit body is formed by covering the surface of the naked type chip unit body with a first fluorescent layer. The color temperature of the naked type chip unit body is different from that of the wrapped type chip unit body. The naked type chip unit body and the wrapped type chip unit body are further covered with a second fluorescent layer. According to the efficient intelligent LED light source, the light-color consistency is good, the light is uniform, the light-color consistency is enhanced after color mixture, the problem that mixed light is partitioned and layered is solved, and the LED light source which is packaged integrally is good in airtightness, high in reliability, high in light-color quality and convenient and fast to manufacture.

Description

technical field [0001] The invention relates to the technical field of high-power LED devices, in particular to an efficient LED intelligent light source. Background technique [0002] Existing high-power LED light sources with adjustable color temperature adopt one color temperature to be fabricated on one side of the substrate, and another color temperature to be fabricated on the other side of the substrate (such as figure 1 ), or made in a circle, one color temperature is made in the inner circle, another color temperature is made in the outer circle, and two different color temperature zones are separated by a building retaining wall in the middle (such as figure 2 ), this production method requires a separate process of building a retaining wall to complete the subsequent separation of different color temperatures. A single separation area is filled with a specified color temperature, and it is difficult to keep consistent filling of the light-emitting surface. Due to...

Problems solved by technology

[0002] Existing high-power LED light sources with adjustable color temperature adopt one color temperature to be fabricated on one side of the substrate, and another color temperature to be fabricated on the other side of the substrate (such as figure 1 ), or made in a circle, one color temperature is made in the inner circle, another color temperature is made in the outer circle, and two different color temperature zones are separated by a building retaining wall in the middle (such as figure 2 ), this production method requires a separate process of building a retaining wall to complete the subsequent separation of different color temperatures. A single separation area is filled with a specified color temperature, and it is difficult to keep consistent filling of the light-emitting surface. Due to the interval between areas, subsequent installation of lenses or reflective bowls When mixing and adjusting light with different color temperatures, it is difficult to make the optical path, and the probability of uneven mixing, color cast, and uneven light spots is high, and the continuity of light color is not good.

[0003] In addition, there is also a method of using split LED lamp beads to mount on the circuit board. If this method is made of a single high-power lamp, the color mixing will be uneven and the glare will be strong; The flatness is difficult to guarantee, the direction of light output will be inconsistent, and the continuity of light color will also be reduced. Due to the use of split LED lamp bead mounting method, there is an extra layer of circuit board, the thermal resistance of the light source will increase accordingly, and the reliability and life of the light source will also decrease. decrease accordingly
