Abstract

The utility model discloses an LED tube light heat dissipation structure capable of enhancing heat dissipation effect by changing direction of heat flow. The LED tube light heat dissipation structure structurally comprises a heat dissipation base and heat dissipation fins, wherein the two faces of a perpendicular heat transfer plate of the heat dissipation base are fixedly connected with the heat dissipation fins, and an air flow channel is reserved between the upper ends of the heat dissipation fins and a horizontal heat dissipation substrate of the heat dissipation base; a plurality of LED light-emitting components are installed on the front face of the heat dissipation base; a front lens is installed in front of the LED light-emitting components; a lens frame is installed around the front lens and the LED light-emitting components; the lens frame is sleeved with a sleeve. The LED tube light heat dissipation structure has the advantages that the vertical heat transfer direction is changed to be the horizontal heat transfer direction, heat is favorable for being smoothly diffused onto the heat dissipation fins so that heat dissipation is enhanced, the upper ends of the heat dissipation fins do not need to be directly connected with the horizontal heat dissipation substrate part of the heat dissipation base due to the change of the direction of the heat flow, the certain air flow channel is reserved, the natural convection heat dissipation effect is more obvious, and the heat dissipation capacity of a whole LED tube light is improved.

Description

Can strengthen by changing direction of heat flow the LED tubular lamp radiating structure of radiating effect

Technical field

The utility model relates to a kind of LED tubular lamp radiating structure of strengthening radiating effect by changing direction of heat flow, belong to lighting field.

Background technology

Along with the development of LED lighting engineering, the application of LED is also more and more extensive, and in lighting field, Down lamp is a kind of more light fixture that uses.The design of tradition LED Down lamp, the heat that the LED luminescence component produces passes to heat dissipation base by vertical direction, if heat dissipation base only has the heat-radiating substrate part of level, so whole radiating fin upper end just must directly be connected with heat-radiating substrate, can't form gas channel between the two, be unfavorable for heat loss through convection, and due to radiating fin upper end shape problem, being difficult to has good contact with the heat-radiating substrate of level, also inconvenience is filled heat conduction class material therein, and heat is difficult to be directly passed to radiating fin by vertical direction.

Visible, the radiator in traditional Down lamp directly is connected with the heat-radiating substrate of LED luminescence component bottom, causes the cross-ventilation in radiator bad, and radiating effect is poor, and the heat that LED produces can not leave in time, has greatly reduced the service life of LED Down lamp.

Summary of the invention

The utility model proposes a kind of LED tubular lamp radiating structure of strengthening radiating effect by changing direction of heat flow, its objective is in order to increase the radiating effect of LED Down lamp, extend the service life of Down lamp.

The concrete solution that the utility model adopts is as follows: its structure comprises cooling base and radiating fin, wherein vertical heat transfer plate two sides and the radiating fin of cooling base are fixedly linked, and between the horizontal heat-radiating substrate of radiating fin upper end and cooling base, leave gas channel; The front of cooling base is equipped with some LED luminescence components; Front lens is arranged on LED luminescence component the place ahead; Lens frame is housed around front lens and LED luminescence component; Lens frame outside cover has sleeve.

The utlity model has following advantage:

1) adopt this LED tubular lamp radiating structure design of strengthening radiating effect by changing direction of heat flow, the heat that the LED luminescence component is produced is conducted to radiating fin by horizontal direction, increased the contact area between cooling base and radiating fin, also facilitated and filled as required heat conduction class material, reduced thermal resistance, made heat more effectively pass to radiating fin and dispelled the heat;

2) adopt this LED tubular lamp radiating structure design of strengthening radiating effect by changing direction of heat flow, make in radiating fin and cooling base and leave certain gas channel between heat-radiating substrate, strengthened cross-ventilation, improved radiating effect.
