Problems solved by technology
However, the heat dissipation of existing LED lamps adopts a fin heat dissipation structure. The fin-shaped heat sink is large and heavy, and the heat sink arranged horizontally is not conducive to air convection, and the heat dissipation effect of the shell is not good; if the shell and the LED substrate are passed through Indirect contact with connecting parts such as claw-shaped feet dissipates heat, and the hidden danger of contact between the shell and the LED substrate is likely to reduce the heat conduction efficiency, and the heat dissipation function of the shell cannot be fully utilized.

Embodiment Construction
[0020] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.
[0021] like figure 1 , figure 2 As shown, an LED lamp with a double-layer heat dissipation casing described in this embodiment includes a casing and an LED substrate 4 provided with an LED chip 5. The LED substrate 4 is arranged on the casing, and the LED The base plate 4 is covered with a lampshade 9 , and the casing is composed of an inner casing 7 and an outer casing 8 , both of which are made of metal. The outer shell 8 and the inner shell 7 are both cylindrical shells with an upward opening. On the one hand, the inner shell 7 and the outer shell 8 are closely matched by the cylindrical surface in contact therebetween, and on the other hand, the inner shell is connected by screws to make the inner shell 8. The bottom surface of 7 is in close contact with the upper bottom surface of the housing 8 . The LED substrate 4 is in close contact with...

The invention designs a light-emitting diode (LED) lamp with a double-layer heat dissipation shell, which relates to an LED lamp and solves the problem that the conventional LED lamp cannot fully fulfill the heat dissipation function of the shell. The LED lamp comprises the shell and an LED substrate provided with an LED chip, wherein the LED substrate is arranged on the shell. The LED lamp is characterized in that: the shell consists of an inner shell and an outer shell, wherein the outer shell is sleeved outside the inner shell, the bottom surface of the outer shell is tightly attached to the LED substrate, and an air flow passage is formed between the inner shell and the outer shell. The heat emitted by the LED chip is transferred to the outer shell and the inner shell through the LED substrate respectively to realize heat dissipation of the double-layer shell of the lamp, the heat dissipation function of the shell is fully fulfilled, the service life of the LED lamp is prolonged, and popularization and development of the high-power LED lamp are further promoted.
Description
technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a double-layer heat dissipation shell. Background technique [0002] Due to the advantages of no toxic substances, environmental protection, and high photoelectric efficiency, LEDs are more and more widely used in the field of lighting. With the development of LED technology, high-power LED lamps are increasing day by day, and high-power LED lamps have a short service life due to heat dissipation problems. If the heat dissipation effect of the lamps can be improved, its service life can be extended. According to research, the lifespan of LED lamps will be doubled for every 10-degree decrease in temperature. Therefore, how to efficiently solve the heat dissipation problem of LED lamps plays a crucial role in the development of LED lamps. However, the heat dissipation of the existing LED lamp adopts a fin heat dissipation structure, and the fin-shaped heat sink is large and heavy, ...
