A connection structure between a lamp cup and a lamp holder of an LED lamp

Abstract

The invention discloses a lamp cup and lamp holder connecting structure of an LED lamp. The lamp cup and lamp holder connecting structure comprises an aluminum lamp cup, and the bottom of the lamp cup is connected with a lamp holder through a connecting part. The connecting part comprises a cylinder, a circle of outwards-protruding ring is arranged at the bottom of the cylinder, and a heat dissipating gap is formed between the outwards-protruding ring and the bottom face of the lamp cup. A thread portion is arranged on the lower portion of the outwards-protruding ring and is connected with the lamp holder, a circle of inwards-protruding ring is arranged on the inner side of a bottom opening of the lamp cup, and crenel grooves are formed in the inwards-protruding ring in the circumferential direction; heat dissipating openings are formed between the crenel grooves and the outer wall of the cylinder of the connecting part, two upwards-protruding bosses are evenly arranged on the outwards-protruding ring in the circumferential direction and are clamped into the crenel grooves. According to the connecting structure, the mode of combining air convection and metal heat absorption is adopted so as to ensure dissipation of heat, and the heat dissipation effect is greatly improved.

Description

[0001] The patent application of the present invention is a divisional application of the invention title "A LED Lamp Heat Dissipation Structure". The filing date of the original application is March 24, 2014, and the application number is 2014101107218. technical field [0002] The present invention relates to LED lamps. Background technique [0003] With the development of LED, it is gradually known to people. Compared with ordinary lights, LED lights have the advantages of long life, energy saving, and environmental protection, and are valued by enterprises of all sizes. However, the high cost of its production has slowed down its entry into ordinary families. LEDs will generate heat during use. If the heat is not dissipated in time, the service life of LED lights will be greatly affected. Therefore, the heat sink of LED lights is usually made of aluminum. Such as figure 1 with figure 2 As shown, the LED lamp is usually composed of a glass bulb 5, a lamp cup 1, a con...

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, the LED lamp is usually composed of a glass bulb 5, a lamp cup 1, a connecting piece 2, and a lamp holder 3, wherein a heat dissipation cover 4 is provided at the mouth of the lamp cup, and a light-emitting electrical element 42 is arranged on the heat dissipation cover 4. The lamp cup 1 is connected and fixed to the lamp holder 3, and its main heat dissipation method is the heat sink 10 provided on the outer wall of the lamp cup 1, and the current conventional technology of the lamp cup is made by pressure injection and machining, that is, the After the aluminum is liquefied, it is injected into the cavity of the mold through the injection equipment. The disadvantages of this method are high production cost, low production efficiency, and the heat dissipation effect is not ideal.
