Ventilation heat-radiating device of LED lamp and ventilation heat-radiating type LED lamp

Abstract

The invention discloses a ventilation heat-radiating device of an LED lamp and a ventilation heat-radiating type LED lamp, relating to the field of LED illumination. The ventilation heat-radiating device of the LED lamp comprises a lamp holder and a lamp cup, wherein an A ventilation hole enabling air to flow in the lamp cup is made on the lamp holder. The ventilation heat-radiating device of the LED lamp also comprises a support body and a ventilation ring, wherein a B ventilation hole is made on an outer ring of the support body, the upper end of the ventilation ring is outwards bent to form a flatly-extending shoulder part which is made into a tooth shape, and ventilation gaps are arranged between the teeth. The ventilation heat-radiating type LED lamp comprises the ventilation heat-radiating device of the LED lamp, and also comprises a lamp hood, a circuit board, a light-emitting diode and a power supply device. The invention has the advantages that the ventilation heat radiation is mainly adopted and changed from metal sheet heat radiation, heat in the lamp is rapidly radiated to air outside the lamp, thus the heat radiation effect is better; and the heat radiation structure is simpler, the consumption of metal materials can be reduced, and the manufacture process is simplified, thus the manufacture cost of the lamp is reduced.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a ventilating heat dissipation device for an LED bulb and a ventilating heat dissipation LED bulb. Background technique [0002] LED lights are a new type of lighting fixtures that have become popular in recent years. There are lamp tubes and bulbs, and the bulbs are called LED bulbs. The LED light source is generally a direct type, and the light emitting center of the LED luminous body faces the light emitting surface. Due to the limitation of the light emitting angle of the LED luminous body itself, the surrounding area of ​​the LED luminous body is often very bright, the heat dissipation effect is not good, and the light is easy to decay. [0003] In the LED light bulbs of the prior art, in order to dissipate the heat quickly, a heat dissipation carrier is usually installed against the circuit board to dissipate heat (radiation device), and the carrier is generally made of metal ma...

The LED light source is generally a direct type, and the light emitting center of the LED light emitting body faces the light emitting surface. Due to the limitation of the light emitting angle of the LED light emitting body itself, the surrounding area of ​​the LED light emitting body is often very bright, the heat dissipation effect is not good, and the light is easy to fade

[0003] In the LED light bulbs of the prior art, in order to dissipate the heat quickly, a heat dissipation carrier is usually installed against the circuit board to dissipate heat (radiation device), and the carrier is generally made of metal material. , and the structure of LED lights becomes complicated, the manufacturing process is cumbersome, and the cost of materials increases, resulting in higher product costs
