Abstract
The utility model discloses a radiator for an LED lamp, which comprises a base and a plurality of radiation fins vertically and parallelly distributed and arranged on the base. An air convection hole is inclinedly and upwardly formed on each radiation fin, and the air convection holes are formed on the same line to form an air convection passage. Compared with the prior art, the radiator provided by the utility model has the advantages that the arrangement of the air convection holes is convenient for air convection according to the principle of heat transfer. Hot air upwardly flows out along the air convection passage formed of the air convection holes, and cold air is supplemented from the air convection holes at the lower end, thereby forming circulating air flow and being favorable for heat radiation. Compared with the prior art, the radiator maximizes heat radiation area, enhances air convection and improves convection radiation efficiency, so as to ensure the light emission efficiency and the service life of the LED lamp.
Description
Technical field
The utility model relates to a kind of radiator, specifically, relates to a kind of LED lamp radiator.
Background technology
Led light source owing to have long, advantages such as energy consumption is low, energy-conserving and environment-protective of life-span, just is being widely used in lighting fields such as urban road, advertising lamp box, automobile as a kind of light source of high benefit.But as characteristics of semiconductor light sources itself, the LED lamp can send a large amount of heats when work, and can the heat that send in time conduct and distribute, and becomes the key factor that influences LED lamp light extraction efficiency and life-span.
As everyone knows, conducting heat comprises conduction, convection current and three kinds of modes of radiation, and these three kinds of modes are all relevant with the size of surface area.Common most of LED lamp is used the area of dissipation that producer is an increase lamp radiator simply, and has ignored the factor of convection current.Also some light fixture has been considered cross-ventilation, as shown in Figure 1, 2, the multi-disc radiating fin 2 of the parallel distribution of vertical arrangement on the radiator that this part LED lamp uses comprises pedestal 1 and is installed in pedestal 1, every radiating fin 2 all has notch 3 in same position, the notch 3 of same position forms chute, and also just having sacrificed area of dissipation on original basis reaches cross-ventilated purpose but open is to chute.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of guaranteeing to increase cross-ventilation under the maximized situation of area of dissipation, improves the LED lamp radiator of heat loss through convection efficient.
For achieving the above object, LED lamp radiator of the present utility model, the multi-disc radiating fin of the parallel distribution of vertical arrangement on comprising pedestal and being installed in pedestal is characterized in that:
Described multi-disc radiating fin has the cross-ventilation hole obliquely successively, and the cross-ventilation hole of offering successively point-blank, forms an air convection channel.
Compared with prior art, advantage of the present utility model is:
According to hot transfer principle, the multi-disc radiating fin has the cross-ventilation hole obliquely successively, and the cross-ventilation hole of offering successively point-blank, forms an air convection channel, and this perforate mode is convenient to cross-ventilation.The air convection channel that hot-air forms along the cross-ventilation hole upwards flows out, and cold air replenishes into from the cross-ventilation hole of low side, forms the air-flow of circulation, and this helps heat radiation.Relative to existing technologies simultaneously, area of dissipation reduce and less than, thereby, under the maximized situation of area of dissipation, increase cross-ventilation, improve heat loss through convection efficient, and then guaranteed the light extraction efficiency and the life-span of LED lamp.
Description of drawings
Fig. 1 is a kind of structure chart of the LED lamp of prior art with radiator;
Fig. 2 is the side view of LED lamp shown in Figure 1 with radiator;
Fig. 3 is a kind of specific embodiment structure chart of LED lamp of the present invention with radiator;
Fig. 4 is the viewgraph of cross-section of LED lamp shown in Figure 3 with radiator.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model LED lamp with radiator is elaborated, so that described those skilled in the art understand the utility model better.In the following description, when perhaps the detailed description of known function that adopts and design can desalinate subject content of the present invention, these were described in here and will be left in the basket.
Embodiment
In the present embodiment, shown in Fig. 3,4, the multi-disc radiating fin 2 of the parallel distribution of vertical arrangement on the LED lamp comprises pedestal 1 and is installed in pedestal 1 with radiator.Described multi-disc radiating fin 2 has cross-ventilation hole 4 obliquely successively, and the cross-ventilation hole of offering successively 4 point-blank, forms an air convection channel.
In this enforcement, the multi-disc radiating fin 2 of vertically arranging parallel distribution is staggered for height, and wherein, low heat emission fin 201 is highly consistent, and high radiating fin 202 increases from radiator two side direction center stairsteppings, and this arrangement mode helps heat exchange.
In this enforcement, multi-disc radiating fin 2 is offered cross-ventilation hole 4 obliquely successively from radiator two side direction centers.As part between Fig. 4 two dotted line L1, L2 is cross-ventilation hole 4, from Fig. 3, Fig. 4, as can be seen, cross-ventilation hole 4 point-blank, and formed air convection channel from the radiator both sides to the center, cold air flows into from the cross-ventilation hole 4 of radiator both sides, and then, 4 air convection channel that form upwards flow along the cross-ventilation hole, shown in the arrow of Fig. 4, flow out at last radiator top, forms the air-flow of circulation, constantly takes away heat.
From present embodiment as can be seen, the utility model LED lamp more helps heat radiation with radiator, and processing cost is low, can be widely used in the powerful lightings such as LED street lamp, LED Tunnel Lamp.
Although above the illustrative specific embodiment of the utility model is described; but should be understood that; the utility model is not limited to the scope of the specific embodiment; to those skilled in the art; as long as various variations appended claim limit and the spirit and scope of the present utility model determined in; these variations are conspicuous, and all utilize innovation and creation that the present invention conceives all at the row of protection.
