The LED lamp heat radiation apparatus has good heat radiation effect and saves production cost.
Description
Technical field
The utility model relates to heat abstractor, relates in particular to the LED heat sink for lamp in a kind of LED lamp field.
Background technology
The LED illuminating lamp mainly is made up of led light source, and common integrated being encapsulated on the led light source substrate of led light source.Because led light source work the time has only 20% electric energy to be converted into luminous energy; All the other electric energy of 80% change heat energy into; Too high temperature can make accelerated ageing of LED own and damage; Thereby do not reach the desirable life-span of led light source, so research and develop and seek the focus that suitable cooling system is a LED illuminating lamp industry always.
The heat that produces when general led light source is worked mainly concentrates on the LED substrate, and substrate adopts aluminum products to carry out heat conduction usually, radiator is set simultaneously dispels the heat.When the power of employed LED lamp is big, because the radiator volume is directly proportional with power, thus when power greatly the time, the increase of radiator volume, the volume of light fixture also can strengthen thereupon, has increased production cost.Because radiator is encapsulated in the light fixture, draw badly simultaneously, its radiating effect is had a greatly reduced quality, thereby influences the service life of light fixture.
The utility model content
The utility model technical problem to be solved is, a kind of raising radiating effect is provided, and the LED heat sink for lamp that can save production cost.
The purpose of the utility model mainly is achieved through following proposal: a kind of LED heat sink for lamp; Comprise the panel, substrate, heat-conducting plate and the radiator that set gradually from top to bottom; Described radiator is provided with and is the spaced fin of emitting shape along the axle center; It is characterized in that, have some air vents on the described panel, have some first louvres on the described substrate; Have some second louvres on the heat-conducting plate, the space between described air vent, first louvre, second louvre and the fin constitutes the air channel that is used to dispel the heat that is interconnected.
Adopt the present technique scheme; On air vent, the substrate first louvre is set being provided with on the panel, heat-conducting plate is provided with second louvre, thereby and the space between the fin constitute the air channel be interconnected, air can get in the air vent of panel like this; Enter into the space between the fin through first louvre and second louvre; Accelerated the circulation of fin ambient air, heat has been discharged rapidly, improved radiating rate through cross-ventilation.Though radiator is packaged in the light fixture, owing to be provided with the air channel, make lamp interior and extraneous circulation, even when the power of LED lamp is big, the utility model also can satisfy the heat radiation requirement of LED lamp, so the light fixture volume need not increase, and has practiced thrift production cost.
Described air vent annular evenly distributes.With the air vent annular spread, can air fully be got into so that air can both get into the air channel in the light fixture from each angle.Simultaneously air vent is evenly distributed, can make the air vent spread geometry seem better appearance.
The arrangement mode of described first louvre and second louvre, quantity, shape are all identical.Adopt this technical scheme, first louvre can be coincide when substrate contacts with heat-conducting plate with second louvre each other, make as far as possible increasing of air channel area.
Described panel, substrate, heat-conducting plate and radiator have coaxial centre bore.Adopt this programme, can make the centre bore of panel, substrate, heat-conducting plate and radiator constitute the air channel that is interconnected, make ventilation effect better.
The shape of cross section of the centre bore of described radiator is a zigzag.Adopt this programme, the area of dissipation of radiator inner surface is increased greatly, make radiating effect more obvious.
The fin of described radiator is the Y type, and fin surface is a waveform.Adopt this programme, the area of dissipation of the outer surface of radiator is increased, reach better radiating effect.
Therefore, it is good to the utlity model has radiating effect, the beneficial effect that saves production cost.

The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
A kind of LED heat sink for lamp; As shown in Figure 1, comprise the panel 1, substrate 2, heat-conducting plate 3 and the radiator 4 that set gradually from top to bottom, described radiator 4 is provided with and is the spaced fin 5 of emitting shape along the axle center; As shown in Figure 5; Fin 5 is the Y type, and fin 5 surface is waveform, and is as shown in Figure 6.Have some air vents 6 on the described panel 1, air vent 6 annulars evenly distribute, and are as shown in Figure 2; Have some first louvres 7 on the described substrate 2; As shown in Figure 3, have some second louvres 8 on the heat-conducting plate 3, as shown in Figure 4; Arrangement mode, quantity, the shape of described first louvre 7 and second louvre 8 are all identical, and promptly second louvre 8 is under first louvre 7.Space between described air vent 6, first louvre 7, second louvre 8 and the fin 5 constitutes the air channel that is used to dispel the heat that is interconnected.Panel 1, substrate 2, heat-conducting plate 3 and radiator 4 have the ventilation air channel that 9, four centre bores of coaxial centre bore, 9 formations are interconnected simultaneously.The shape of cross section of the centre bore 9 of described radiator 4 is zigzag, and is as shown in Figure 5.
Adopt the present technique scheme and since be provided with on the panel first louvre 7 is set on air vent 6, the substrate 2, heat-conducting plate 3 is provided with second louvre 8, thereby and the space between the fin 5 constitute some air channels that are interconnected; When the LED lamp was worked, air is through getting in the air vent of panel, and was as shown in Figure 7; A plurality of air channels through the formation of the space between first louvre 7 and second louvre 8 and the fin 5; Accelerated the circulation of fin 5 ambient airs, heat has been discharged rapidly, reached effect preferably through convection current; Even when the power of LED lamp is big; The utility model also can satisfy the heat radiation requirement of LED lamp, so the volume of light fixture no longer is subject to the size of LED lamp power, has practiced thrift production cost.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can make some changes or modification to the structure of heat abstractor after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
