Abstract
The utility model discloses a light-emitting diode (LED) lamp heat radiator which comprises a heat radiator body. The heat radiator body is provided with a concave hole for placing an electric appliance element, and the surface of the heat radiator is provided with a columnar heat radiation body. The LED lamp heat radiator adopts the columnar heat radiation body, the heat radiation area is larger than that of an existing heat radiator, heat is radiated out through heat exchange of the heat radiation body and air, and the air circulation speed is high, so that the heat radiation speed is high, and the heat radiation effect is good. In addition, the LED lamp heat radiator is not easily damaged, long in service life, safe and reliable, light source decay of an LED is increased, the service life of an LED spotlight is prolonged, and the LED lamp heat radiator can be widely applied for large-area illumination. After the LED lamp heat radiator is used, the work temperature of a lamp foot of the LED spotlight is kept to be 38-48 DEG C. Compared with LED spotlights using existing heat radiators, the temperature of the lamp foot is reduced by 11-15 DEG C, and the LED spotlight powered on normally can have no brightness decay within 5000 hours.

Great power LED is a direction of LED industry future development, but great power LED has relatively high expectations to heat dissipation technology, and the power of led module is more big, and the heat flow density of its chip is just more high.The temperature of led chip sharply rises when the heat-conducting effect of radiator is bad, the very fast generation light decay of meeting, even damage led chip.Have only the heat dissipation technology that solves great power LED, delay the light decay of LED to greatest extent, could promote the application of great power LED widely.
At present, the heat radiation of high-power LED module is adopted plate shaped extrusion section bar electronic radiation device mostly or is adopted aluminium ingot Digit Control Machine Tool processing heat radiator and hot pipe technique.The radiator of a kind of LED light fixture of announcing as CN201020296466.8, comprise the heat radiation lamellar body, the heat radiation lamellar body comprises fin and the flat board that fin is linked together, it is characterized in that: there is the heat radiating fin that is upturned and launches at the two ends of described flat board, dull and stereotyped heat radiating fin with its two ends constitutes the cross section and is flat V-arrangement, and flat board and heat radiating fin are Heat Conduction Material.The geometry of the radiator of this structure is fixing, and volume is big, and inconvenience is installed, and is poor with LED radiator structure matching; Hot pipe technique cost height, easy dust stratification dirt in the fin, and development cost are very high.
The utility model content
In order to address the aforementioned drawbacks, the utility model provides that a kind of cost is low, good, easy for installation with LED radiator structure matching, the LED lamp radiator of good cooling effect.
For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of LED lamp radiator, comprise radiator body, described radiator body is provided with for the shrinkage pool of placing electric elements, and the surface of described radiator body is provided with the column radiator.
Rounded or the rectangle in the cross section of described column radiator or rhombus or triangle are trapezoidal or oval.
Described column radiator is to distribute along the circumferencial direction of described radiator body.
Described radiator body is cylinder or cuboid.
Described column radiator is well word shape and arranges in length and breadth.
The central authorities of described radiator are provided with fixedly protection mechanism of power line.
Described power line fixedly protection mechanism comprises collet and wire clamp.
The utility model adopts the column radiator, area of dissipation is wideer than existing radiator, with the heat exchange of air heat is distributed, circulation of air speed is fast, so radiating rate is faster, radiating effect is better, the utility model column radiator is not fragile simultaneously, long service life, safe and reliable, the light source decay of LED is increased, prolong the service life of LED shot-light, can be applied on the large area lighting widely.After the utility model used, the lamp base operating temperature of LED shot-light remained on the 15-40 degree, compared with the LED shot-light that uses existing radiator, and the lamp base temperature has reduced the 11-15 degree, can make LED shot-light normal power-up work 50000 hours, and year light decay control is in 5%.
