Abstract
The utility model relates to a radiator of LED lamp. The radiator comprises a radiating substrate tightly attached to the LED heating diode circuit board and radiating fins connected with the substrate, the substrate and the radiating fins are of an integrated structure, each radiating fin radiates outwards and is divided into 2 pieces, a heat conducting hole is formed in the joint of the root of each radiating fin and the substrate, and an air conducting channel is formed in the middle of one quantity of radiating fins. Because root fin thickness is thin, and is nearer from LED heating diode circuit board, and heat conduction is fast, and its surface temperature is higher, and its heated air speed is very fast, and the thickness of tip is thick, and when its heat conduction was to the tip, tip surface temperature is lower, and it is equipped with the heat conduction hole at the root, and the hot-air is discharged easily, forms the convection current in the fin space easily for the radiating effect improves greatly.
Description
Technical field
The utility model relates to a kind of LED lighting, refers in particular to a kind of heat abstractor of LED lighting source here.
Background technology
At present, the environmental protection and energy saving product becomes the main flow of consumer products more, like illuminating product; Common incandescent lamp is slowly withdrawn from the market, and fluorescent lamp and LED lamp become the main flow in market more, in recent years; The LED light fixture has obtained development fast, just progressively gets into the general lighting field.Compare with traditional incandescent osram lamp and fluorescent lamp; The LED light fixture has that volume is little, caloric value is low, the advantage that power consumption is little, and can start by the low pressure low current; Reaction speed is fast and the ability high frequency time is operated, long service life, thereby the title of " green illumination light source " is arranged.
Existing LED street lamp includes dozens of LED light emitting diode or more more; The gross calorific power of these LED light emitting diodes is very big during work; These heats accumulate in a large number in the less space and can not distribute rapidly, and when LED and environment temperature reached balance, the temperature of LED was very high; Thereby cause the decay of LED illumination and aging rapidly, shorten service life greatly.
Summary of the invention
The purpose of the utility model provides a kind of radiator with LED lamp of excellent heat dispersion performance.
The utility model solves the technical scheme that its technical problem adopted:
A kind of radiator of LED lamp; Radiator comprises the heat-radiating substrate of being close to LED heating diode circuit plate; The fin that is connected with substrate, substrate and fin are structure as a whole, and each fin is to external radiation and be divided into 2 bursts; Be provided with thermal hole at fin root and substrate junction, in the middle of the fin of a quantity, be provided with the wind-guiding road.
The thickness of described fin root is less, and end portion thickness is bigger.
Described fin is an arc.
The beneficial effect of the utility model is: because root fin thin thickness, and nearer from LED heating diode circuit plate, the heat conduction is fast; Its surface temperature is higher, and its heating air velocity is very fast, and end portion thickness is thicker; When its heat was transmitted to the end, the end surface temperature was lower, and it is provided with thermal hole at root; Hot-air is discharged easily, forms the convection current of air nature easily in the fin space, makes radiating effect improve greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the structural representation that the utility model is installed;
Fig. 2 is the cutaway view Amplified image of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
See shown in Fig. 1-2 that the radiator of a kind of LED lamp that the utility model discloses is installed in the outside of LED lamp 1 shown in Figure 1; See shown in Figure 2ly, radiator comprises the heat-radiating substrate of being close to LED heating diode circuit plate 2, the fin 3 that is connected with substrate; Substrate 2 is structure as a whole with fin 3, and each fin 3 is to external radiation and be divided into 2 bursts 31, can strengthen radiating effect; Fin 3 also can adopt single chip architecture or multi-sheet structure, is decided by the power of LED lamp.In order to increase the contact area of fin 3 and air, promote radiating effect, fin 3 can adopt arc.Be provided with thermal hole 4 at fin 3 roots and substrate junction, in the middle of the fin of a quantity, be provided with wind-guiding road 5.But heated air thermal hole 4 is derived, and through wind-guiding road 5 hot-air is seen off.
The thickness of described fin 3 roots is less, and end thickness is bigger; Because root fin 3 thin thickness, and nearer from LED heating diode circuit plate, the heat conduction is fast; Its surface temperature is higher, and its heating air velocity is very fast, and end portion thickness is thicker; When its heat was transmitted to the end, the end surface temperature was lower, and was provided with thermal hole at root; Hot-air is discharged easily, forms the convection current of air nature easily in fin 3 spaces, makes radiating effect improve greatly.
