Embodiment Construction

[0014] Such as image 3 , Figure 4 shown. A light-emitting diode with adjustable color temperature and color rendering, including a base 1, on which an electroluminescent blue LED unit 2 and a second LED unit 3 are installed, and the blue LED unit 2 and the second LED unit 3 are packaged together in the package 4. The package body 4 is made of epoxy resin, silica gel or other transparent materials; the package body 4 is scattered with yellow phosphor powder covering the blue LED unit 2 and the first LED unit 3 .

[0015] The blue LED unit 2 includes a blue LED chip 21 , the cathode and anode of the blue LED chip 21 are electrically connected to electrodes 51 , 52 , and an external power supply provides driving current for the blue LED unit 2 through the electrodes 51 , 52 . The blue LED unit 2 is a conventional structure, which will not be described in detail here.

[0016] The second LED unit 3 and the above-mentioned blue LED unit 2 are installed on the base 1 at interv...

Abstract

The invention relates to an LED, in particular to an LED with functions of adjusting the color temperature and improving the color rendering. The LED comprises a substrate, an electrical induced blue light emitting LED unit arranged on the substrate, and a packaging body with yellow fluorescent powder distributed. The LED is characterized by further comprising a first LED unit comprising at least one electrically induced red light emitting LED wafer, the electrical induced blue light emitting LED unit and the first LED unit are connected with respective drive power sources through electrodes, and the electrical induced blue light emitting LED unit and the first LED unit are packaged in the packaging body. The LED with the functions of adjusting the color temperature and improving the color rendering can overcome the defect that the color rendering performance of a common LED is poor, and can improve the color rendering performance of the LED, especially the color rendering performance and brightness when color temperature is low.

Description

technical field [0001] The invention relates to a light-emitting diode, in particular to a light-emitting diode with adjustable color temperature and improved color rendering. Background technique [0002] Light-emitting diode (LED), a semiconductor component, was initially used as indicator lights, display panels, etc.; with the emergence of white LEDs, it was also used as lighting; due to its high efficiency, long life, recyclability, and shock resistance It is widely used in many fields because of its incomparable advantages such as good performance and not easy to be damaged by traditional light sources. refer to figure 1 , figure 2 . The existing LED comprises a base 1, an electroluminescent blue LED unit 2 disposed on the base, and a package body 4 scattered with yellow phosphor powder. The blue LED chip 21 of the blue LED unit is packaged in the package body 4, and the blue LED chip The cathode and anode of 21 are electrically connected to the electrodes 51 and 5...
