Problems solved by technology
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. The existing LED packaged lamp cups generally adopt the structure of packaging 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 problem of the LED lamp with this structure is that the lamp cup is large in size, which affects its performance, and the light diffusion is relatively poor, which is more The most important thing is that 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
[0050] Please refer to Figure 1 to Figure 6 As shown, it shows the specific structure of the first embodiment of the present invention. It is a double-cup LED lamp with adjustable color temperature, display finger and colorful colors. It can adjust R, G, B, W at will. Various colors, as well as the colorful light with adjustable color temperature and obvious finger formed by the mixture of these basic tones, are used for decoration to create different artistic conceptions. The structure of this kind of LED lamp includes an insulating body 10 , four sets of conductive terminals 21 , 22 , 23 , 24 , four LED chips 31 , 32 , 33 , 34 , a fluorescent powder adhesive layer 41 and a transparent adhesive layer 42 .
[0051] Wherein, the insulating body 10 is made of plastic material, see image 3 , the shape of the insulating body 10 is a square, and the ratio of its length and width to two sides is A1:A2=1:1. A cup body is recessed on the top surface of the insulating body 10 , and...

The invention discloses a color temperature and color rendering index adjustable type two-cup colorful LED lamp. The LED lamp comprises an insulation body, four independent sets of conductive terminals and four LED wafers, wherein two reflection cups are obtained by separating the insulation body through a longitudinal partition wall. The wafers between the two reflection cups are arranged in two modes, wherein the first mode is that LED wafers in red and blue are arranged in one reflection cup provided with a fluorescent powder glue layer through injection, and LED wafers in blue and green are arranged in the other reflection cup provided with a transparent glue layer through injection, and the second mode is that the two reflection cups are respectively provided with LED wafers in red and blue and provided with fluorescent powder glue layers through injection with different proportions. By means of the different LED wafers in the two reflection cups or the different proportions of the fluorescent powder glue layers and due to the fact that each LED wafer corresponds to one set of conductive terminals, power supply voltage and current can be adjusted freely, and then colorful mix light with different color temperatures and different color rendering indexes can be obtained.
Description
technical field [0001] The invention relates to the technology in the field of LED lamps, in particular to a double-cup LED lamp with adjustable color temperature, finger display and colorful colors. 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. The existing LED packaged lamp cups generally adopt the structure of packaging 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 problem of the LED lamp with this structure is t...
