Problems solved by technology

This kind of LED lighting product requires two kinds of white LED lamp beads with different color temperatures. Therefore, on the one hand, the cost is relatively high, and at the same time, the color deviation is large when the two kinds of white LED lamp beads are mixed; on the other hand, it needs to be divided into two parts. White LED lamp beads with different color temperatures are mounted on the circuit board, which increases the operation process. The difficulty of pretending

Embodiment 1

[0028] A light-emitting device capable of adjusting color temperature proposed in this embodiment, such as Figure 1 to Figure 7 As shown, it includes a substrate 1, on which an LED light source 2 capable of emitting white light with two different color temperatures is installed. The LED light source 2 includes a bracket 21, a first chip group consisting of three first blue light chips 22, The second chipset composed of three second blue light chips 23, the first phosphor used to package the first chipset, the second phosphor used to package the second chipset, the bracket 21 is electrically connected to the substrate 1, and the second A chip group and a second chip group are arranged in the bracket 21 and are respectively electrically connected to the bracket 21, the white light emitted by the first blue light chip 22 after exciting the first phosphor powder and the white light emitted by the second blue light chip 23 after exciting the second phosphor powder. The color tempe...

Embodiment 2

[0038] A light-emitting device capable of adjusting color temperature proposed in this embodiment is basically the same as the light-emitting device in Embodiment 1, the only difference is that: Figure 8 As shown, the three first blue light chips 22 are connected in parallel, one end is electrically connected to the first electrode 261 after the parallel connection, and the other end is electrically connected to the second electrode 262 after the parallel connection; the three second blue light chips 23 are connected in parallel, After the parallel connection, one end is electrically connected to the third electrode 263 , and after the parallel connection, the other end is electrically connected to the fourth electrode 264 .

Embodiment 3

[0040] A light-emitting device capable of adjusting color temperature proposed in this embodiment is basically the same as the light-emitting device in Embodiment 1, the only difference is that: Figure 9 and Figure 10 As shown, the structure of the substrate 1 is a strip structure, and a plurality of lamp board pads 11 are evenly arranged on the substrate 1 along the length direction. , one LED light source 2 is welded on each light board pad 11 .

[0041] In each of the above-mentioned embodiments, the first chipset can also be composed of only one first blue-ray chip 22, and the second chipset can also be composed of only one second blue-ray chip 23; the substrate 1 can be a flexible circuit board, and the substrate 1 It can also be designed into other shapes according to actual needs; the first blue light chip 22 and the second blue light chip 23 both adopt the existing LED blue light chip; the first phosphor powder and the second phosphor powder adopt the existing phosp...

Abstract

The invention discloses a light-emitting device capable of adjusting color temperature. The device comprises a substrate, and an LED light source capable of emitting white light with at least two different color temperatures is arranged on the substrate. The device has the advantages that one LED light source capable of emitting white light with at least two different color temperatures is adopted, so that the light-emitting device can achieve color temperature adjustment by adopting one LED light source, the LED light source is small in color deviation and uniform in light emitting during mixed color light emitting, meanwhile, due to the fact that the LED light source does not need to be installed in two times, operation procedures are reduced, labor cost is reduced, installation on a small-size substrate is facilitated, and operation is convenient.

Description

technical field [0001] The invention relates to an LED lighting product, in particular to a light emitting device capable of adjusting color temperature. Background technique [0002] Existing LED lighting products usually need to use two kinds of white LED lamp beads with different color temperatures to adjust the color temperature. By changing the current input to the white LED lamp beads with different color temperatures, the brightness of the white LED lamp beads with different color temperatures can be changed to adjust the color temperature. . This kind of LED lighting product requires two kinds of white LED lamp beads with different color temperatures. Therefore, on the one hand, the cost is relatively high, and at the same time, the color deviation is large when the two kinds of white LED lamp beads are mixed; on the other hand, it needs to be divided into two parts. White LED lamp beads with different color temperatures are mounted on the circuit board, which incre...
