| Zusammenfassung: | The invention belongs to the technical field of light sources, and provides a COB light source with adjustable color temperature, which comprises a substrate, a plurality of LED chips and at least two kinds of fluorescent glue with different color temperatures, the plurality of LED chips are mounted on the substrate and are connected in series and/or in parallel through wires, each LED chip is covered by at least one kind of fluorescent glue, and the fluorescent glue is arranged on the substrate. Wherein the fluorescent glue with the highest color temperature covers the other fluorescent glue with the lower color temperature. According to the COB light source with the adjustable color temperature, the fluorescent glue with at least two different color temperatures is adopted, the fluorescent glue with the highest color temperature covers the fluorescent glue with the lower color temperature, so that the fluorescent glue with the highest color temperature can be excited after an LED chip covered with the fluor |
