Abstract
The utility model discloses an LED (Light Emitting Diode) lamp comprising a lamp head and a radiator, wherein an LED light source and a glass shell is arranged at the upper end of the radiator; a plurality of radiating fins are longitudinally arranged on the outer surface of the radiator; and from the upper end to the lower end of the radiator, the widths of the radiating fins are gradually decreased. According to the LED lamp, the radiating fins on the LED lamp are longitudinally arranged; the widths of the radiating fins are gradually decreased from the end close to the LED resource to the other end far away from the LED resource; the heat generated at the end close to the LED resource is large and needed to be dissipated as soon as possible so that the radiating fins at the end are thicker; the heat generated at the other end far away from the LED resource is little so shat the radiating fins at the other end are thinner; the structure of the radiating fins of the utility model is reasonable, and the heat can be quickly dissipated; and therefore, the service life and the performance of the LED lamp are improved.
Description
Technical field
The utility model relates to a kind of LED light fixture.
Background technology
LED had obtained swift and violent development in recent years as a kind of emerging light source, and various LED application products have all embodied the incomparable advantage of conventional lamp, and had tentatively obtained the approval in market.But in the existing LED light fixture product commonly used,, basically all adopted the metal material of high thermal conductivity to do radiator shell, and utilized radiator shell to dispel the heat in order to solve the very crucial heat dissipation problem of LED.But the shape of fin is varied, vertical setting is arranged, and horizontally set is also arranged, relatively arbitrarily, so radiating effect also has certain difference.
The utility model content
The utility model has overcome the deficiency that exists in the above-mentioned prior art, provides a kind of rational in infrastructure, is beneficial to the LED light fixture of heat radiation.
The technical scheme of the utility model is achieved in that
A kind of LED light fixture comprises lamp holder, and radiator is provided with led light source and glass bulb in the radiator upper end, on the outer surface of radiator, vertically is provided with a plurality of fin, and to the lower end, the width of described fin diminishes gradually from the radiator upper end.
As preferably, the Breadth Maximum of fin is 3～5mm, and the minimum widith of fin is 1～2mm.
Adopted the beneficial effect of the utility model of technique scheme to be:
Fin on the utility model LED lamp radiator is vertically to be provided with; And the width of fin diminishes from an end to this end away from led light source near led light source gradually; The heat that produces near this end of led light source is big, need distribute as early as possible, and fin is thicker; And few away from this end heat of led light source, the fin width can be thinner; The structure of the fin of the utility model is provided with rationally, can heat be distributed faster, has improved service life and the performance of LED.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The specific embodiment of the utility model is following:
Embodiment: the LED light fixture, as shown in Figure 1, comprise lamp holder 1; Radiator 2 is provided with led light source 5 and glass bulb 3 in radiator 2 upper ends, on the outer surface of radiator 2, vertically is provided with a plurality of fin 4; To the lower end, the width of described fin 4 diminishes gradually from radiator 2 upper ends.
The Breadth Maximum of fin 4 is 4mm, and the minimum widith of fin 4 is 1.5mm.
