Heat dissipation method of LED lamp and LED lamp adopting same

[0029] Embodiment one

[0030] A kind of LED lamp, refer to figure 1 , including a lamp holder 1, a plastic shell 2, a glass shell 3, a heat dissipation component 4, an LED assembly 5 and a power supply module for powering the LED assembly 5, which is not shown in the figure. The plastic case 2 is connected between the lamp cap 1 and the glass case 3 , and the above-mentioned power module can be arranged in the plastic case 2 to supply power for each LED assembly 5 . The heat dissipation component 4 is built in the glass shell 3, and a heat transfer cavity 30 is formed between the heat dissipation component 4 and the glass shell 3, and the heat transfer cavity 30 is filled with a heat transfer medium gas. Each LED assembly 5 is pasted on the heat dissipation component 5 through the heat conduction substrate 51 .

[0031] refer to figure 1 , the heat dissipation component 4 is a cup-shaped body with a stepped side wall. Each LED assembly 5 is arranged on the bottom surface of

[0033] Embodiment two

[0034] refer to figure 2 , the structure of this embodiment is basically the same as that of Embodiment 1, the only difference is that each LED assembly 5 of this embodiment is arranged on the side of each step of the cup-shaped heat dissipation part 4, and the side of each step is a tapered surface, Therefore, the light emitting angle of this embodiment is larger than that of the first embodiment.

[0035] Embodiment Three

[0036] refer to image 3 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference between the two is that the cup mouth of the cup-shaped heat dissipation part 4 faces the side of the glass shell 3, and the heat dissipation part 4 is concave inward when viewed from the side of the glass shell 3 of. Each LED assembly 5 is also arranged on the bottom surface of each step of the cup-shaped heat dissipation component 4 . In order to adapt to the shape of the heat dissipation part 4 , the shape of the glass envelope 3 of this embodiment is also different from that of the first embodiment.
