Abstract
The invention discloses an LED lamp which comprises a lamp head and a radiator. An LED light source and a glass shell are arranged at the upper end of the radiator, multiple radiating fins are longitudinally arranged on the outer surface of the radiator, and the thickness of the radiating fins gradually decreases from the upper end to the lower end of the radiator. The radiating fins are longitudinally arranged on the radiator, the width of the radiating fins gradually decreases from one end close to the LED light source to one end distant from the LED light source, more heat is generated at the end close to the LED light source and needs to be diffused as soon as possible, the radiating fins are thicker; less heat is generated at the end distant from the LED light source, and the width of the radiating fins can be smaller. The radiating fins of the LED lamp are reasonable in structural arrangement, heat can be diffused quickly, the service life of the LED lamp is prolonged, and performance of the LED lamp is improved.
Description
Technical field
The present invention 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, in order to solve the very crucial heat dissipation problem of LED, substantially all adopted the metal material of high thermal conductivity to do radiator shell, and utilized radiator shell to dispel the heat.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.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, is beneficial to the LED light fixture of heat radiation.
Technical scheme of the present invention 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, vertically is provided with a plurality of fin on the outer surface of radiator, and to the lower end, the thickness of described fin diminishes gradually from the radiator upper end.
As preferably, the maximum ga(u)ge of fin is 3～5mm, and the minimum thickness of fin is 1～2mm.
Adopted the invention has the beneficial effects as follows of technique scheme:
Fin on the LED lamp radiator of the present invention is vertically to arrange, and the thickness of fin diminishes gradually from an end to this end away from led light source near led light source, the heat that this end of close led light source produces is big, need distribute as early as possible, fin is thicker, and few away from this end heat of led light source, fin thickness can be thinner; The structure of fin of the present invention arranges rationally, heat can be distributed faster, has improved service life and the performance of LED.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of LED light fixture as shown in Figure 1, comprises lamp holder 1, radiator 2 is provided with led light source 5 and glass bulb 3 in radiator 2 upper ends, circumferentially vertically is provided with a plurality of fin 4 in the outer surface upper edge of radiator 2, to the lower end, the thickness of described fin 4 diminishes gradually from radiator 2 upper ends.
The maximum ga(u)ge of fin 4 is 2.5mm, and the minimum thickness of fin 4 is 1.5mm.
Claims (2)
