Problems solved by technology
Existing LED packaging lamp cups generally adopt the structure of encapsulating a single LED chip in a lamp cup, and make the lamp cup deeper, and fill the lamp cup with glue to fix the LED chip. The LED lamp with this structure exists The problem is that the lamp cup is large in size, which affects its performance, and the light diffusion is relatively poor. More importantly, a lamp cup can only produce a single white light with a single light color, which cannot meet the needs of some special occasions.

Embodiment Construction
[0039] Please refer to Figure 1 to Figure 6 As shown, it shows the specific structure of the first embodiment of the present invention. The LED lamp with adjustable color temperature and display finger includes an insulating body 10, three sets of conductive terminals 21, 22, 23, three LED chips 31, 32, 33 and two kinds of fluorescent powder glue layers 41 with different proportions. , 42.
[0040] Wherein, the insulating body 10 is made of plastic material, see image 3 , the shape of the insulating body 10 is square. A cup body is recessed on the top surface of the insulating body 10 , and a non-transparent longitudinal partition wall 11 is provided at the center of the cup body to divide the cup body into two to form a first reflective cup 12 and a second reflective cup 13 . The two fluorescent powder adhesive layers refer to the first fluorescent powder adhesive layer 41 and the second fluorescent powder adhesive layer 42 with different proportions respectively, the fi...

The invention discloses an LED lamp allowing color temperatures and color indexes to be adjusted. The LED lamp comprises an insulating body, three sets of conductive terminals which are independently powered up, a red light LED wafer, a first blue light LED wafer, a second blue light LED wafer and two types of fluorescent powder adhesive layers different in ratio. The insulating body is separated into two reflection cups through a longitudinal partition wall. The red light LED wafer and the first blue light LED wafer are installed in one reflection cup. The second blue light LED wafer is installed in the other reflection cup. The two types of fluorescent powder adhesive layers different in ratio are injected into the two reflection cups. In this way, one type of white light variable in color temperature is emitted jointly by the red light LED wafer and the first blue light LED wafer and penetrates through the first fluorescent powder adhesive layer, and the other type of white light variable in color temperature is emitted by the second blue light LED wafer and penetrates through the second fluorescent powder adhesive layer. Besides, all the LED wafers are powered up by the independent conductive terminals, brightness of different wafers can be controlled by adjusting voltage and current at will, and therefore mixed light variable in color temperature, different in color index and adjustable in intensity can be obtained through adjustment.
Description
technical field [0001] The invention relates to the technology in the field of LED lamps, in particular to an LED lamp with adjustable color temperature and finger display. Background technique [0002] Light-emitting diodes (LEDs or LEDS) are solid-state devices that convert electrical energy into light energy. They have long service life, high color rendering index, energy saving and environmental protection, high brightness, and wide application. Various countries are vigorously advocating the development of the LED industry. In recent years, the progress of science and technology has led to the popular trend of LED packaged lamp cups with smaller volume, complex structure and diversified light colors. Existing LED packaging lamp cups generally adopt the structure of encapsulating a single LED chip in a lamp cup, and make the lamp cup deeper, and fill the lamp cup with glue to fix the LED chip. The LED lamp with this structure exists The problem is that the lamp cup is b...
