Embodiment Construction

[0011] Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the specific embodiments described here are merely examples and are not intended to limit the protection scope of the present invention.

[0012] See figure 1 , Which is a schematic structural diagram of an LED lamp 100 with a heat dissipation structure provided by the present invention. The LED lamp 100 with a heat dissipation structure includes a hollow lamp housing 10, a light source placement table 11 provided on the inner wall of the hollow lamp housing 10, and at least one connecting the inner wall of the lamp housing 10 and the light source placement table 11 The connecting arm 12 and an LED light source 13 arranged on the light source placement table 11. Of course, it is conceivable that the LED lamp 100 with a heat dissipation structure also includes other functional elements, such as a power supply module, installation and a...

Abstract

Disclosed is an LED lamp with a heat dissipation structure. The LED lamp with the heat dissipation structure comprises a hollow lamp shell, a light source holding platform, at least one connection arm and an LED light source. The lamp shell comprises an air inlet and an air outlet in the axial direction of the lamp shell. The sectional area, in the radial direction of the lamp shell, of the air inlet is larger than or equal to the sectional area, in the radial direction of the lamp shell, of the air outlet. The connection arm is used for making a light source arrangement disk and the inner wall of the lamp shell be arranged at intervals to form a ventilation channel. The LED light source emits heat to make the air temperature in the lamp shell rise, and upward buoyancy is generated. Meanwhile, the air pressure is increased, and then air on the air inlet side flows upwards, flows toward the air outlet through the ventilation channel between the light source arrangement disk and the inner wall of the lamp shell, and flows out of the lamp shell. Meanwhile, due to the fact that the air flows upwards to form suction force to the air at the air inlet, the air near the air inlet enter the lamp shell. The process is repeated, and in this way, effective natural convection is formed to bring the heat generated by the LED lamp out of the lamp shell, so that the service life of the high-power LED lamp is prolonged.

Description

Technical field [0001] The invention relates to a lighting system equipment, in particular to an LED lamp with a heat dissipation structure. Background technique [0002] In general daily life, various lighting equipment can be seen everywhere, such as fluorescent lamps, street lamps, desk lamps, artistic lamps, etc. In the above-mentioned lighting equipment, most traditionally use tungsten bulbs as the light source. In recent years, due to the rapid development of technology, light-emitting diodes (LEDs) have been used as light sources. What's more, in addition to lighting equipment, general traffic signs, billboards, car lights, etc. are also changed to use light-emitting diodes as light sources. As mentioned above, the advantages of using light-emitting diodes as light-emitting sources are power saving and greater brightness, so the use has gradually become common. [0003] With the popularity of LED lamps, LED lamps are used in more and more occasions, such as shopping malls...
