Abstract

The invention discloses an all-angle even-light-emitting high-power LED lamp bar with fluorescent powder and chips separated. The LED lamp bar comprises an inner portion and an outer portion, an LED transparent ceramic strip where the LED chips are evenly attached is arranged on the inner portion, the inner portion is sealed by silica gel in a filling mode, microstructures for damaging total reflection are arranged on the strip, an acrylic tubular bar coated with the yellow fluorescent powder is arranged on the outer portion, and the shape of acrylic tubular bar is designed according to the contour line of LED luminous intensity. According to the LED lamp bar, a fixed module coated with the fluorescent powder and an LED luminous module coated with the fluorescent powder can be manufactured respectively, flexible combination is achieved, and the purposes of high yield, low production cost, long service life, high luminous efficiency and all-angle even light emitting are achieved easily.

Description

technical field [0001] The invention relates to an LED light bar, in particular to a high-power LED light bar in which fluorescent powder is separated from a chip and emits light uniformly at all angles. Background technique [0002] In recent years, LED lighting technology has developed by leaps and bounds, especially the development of LED light strip technology, which has rapidly replaced traditional incandescent lamps with its advantages of high light efficiency, high reliability, long life, and environmental protection. However, as a traditional lighting fixture, incandescent lamps have mature production technology and low cost, and are still the choice of lighting sources for many ordinary people. If LEDs are to fully replace incandescent lamps for indoor lighting, in addition to maintaining the advantages of LEDs such as high luminous efficiency and long life, the cost of LED lamps must be further reduced. [0003] LED light strips are divided into two categories: so...
