Publication number: 20190132925Abstract: An LED circuit with color temperature adjustment comprises a first LED string, a resistor, and a second LED string. The first LED string has a first color temperature. The resistor is connected in series with the first string. The second LED string has a second color temperature. The first LED string is connected in parallel with the second LED string. The second color temperature is higher than the first color temperature. The integrated color temperature of the first LED string and the second LED string increases when the total current of the first LED string and the second LED string increases. The present disclosure not only can provide an LED circuit with color temperature adjustment, but also can provide an LED circuit which can adjust the color temperature by the combinations of the LED strings connected in parallel or series.Type: ApplicationFiled: December 27, 2018Publication date: May 2, 2019Inventors: Qiyuan Wang, Wenchang Huang, Guangai Chen, Huiwu Chen

Publication number: 20190097105Abstract: A light emitting diode element apparatus has a flip chip, an encapsulating structure and a fluorescent layer. The flip chip has a light emitting diode element with two chip electrodes. The two chip electrodes are set below the light emitting diode element. The upper side of the light emitting diode element emits light when the sidewall is electrically conducting. The encapsulating structure has a support seat, at least one reflective wall and two encapsulating electrodes. The two encapsulating electrodes are electrically connected to the two chip electrodes through solder, the flip chip being disposed on the support base. The at least one reflective wall directed toward the side wall of the light emitting diode element to direct light emitted from the side wall of the light emitting diode element to a predetermined direction. The present invention also discloses a method of manufacturing the light emitting diode apparatus.Type: ApplicationFiled: January 3, 2018Publication date: March 28, 2019Inventors: Liangliang Cao, Qiyuan Wang
