Tubular metal hot airflow radiator for LED fluorescent lamp tube

Abstract

The invention provides a tubular metal hot airflow radiator for an LED fluorescent lamp tube. A plurality of LED filaments are mounted on the tubular metal hot airflow radiator so as to enable the LED filaments to run through the fluorescent lamp tube internally. During use, hot airflow is formed in the tubular metal hot airflow radiator, so that heat generated by the LED filaments is pumped out from the tubular metal hot airflow radiator and then is discharged. Since the hot airflow only passes the tubular metal hot airflow radiator internally and does not enter the fluorescent lamp tube, dust does not gather in the fluorescent lamp tube and the situation that an illumination effect is affected due to dust gathering of the LED filaments is avoided. The problems that the LED fluorescent lamp tube is poor in heat dissipation effect and the illumination effect of an LED fluorescent lamp capable of heat dissipation is affected due to dust gathering of the LED filaments caused by the fact the hot airflow passes the lamp tube internally are solved. The tubular metal hot airflow radiator has the advantages that the size is small, the weight is light, the cost is low, the heat dissipation effect is good, dust does not gather in the lamp tube, and an excellent market development prospect is realized.

Description

technical field [0001] The invention relates to a radiator, in particular to a tubular metal hot air radiator for an LED fluorescent lamp. Background technique [0002] At present, the radiators of LED fluorescent lamps on the market are mainly semi-cylindrical aluminum radiators, and half of the entire fluorescent tube is composed of aluminum radiators. Its main disadvantages are heavy weight and high cost. And a kind of heat-dissipating LED fluorescent lamp that appears newly, because be provided with the hot air discharge pipe that communicates with the inside of lamp tube, form a hot air flow passage together with fluorescent tube, can reduce the volume and the weight of radiator. But there is a serious problem: the hot air flow passes through the fluorescent tube for a long time, and a large amount of dust will be accumulated in the fluorescent tube, so that the LED wick will affect the lighting effect due to the accumulation of dust.
