Abstract
An LED lamp comprises LED lights and a radiator. The radiator comprises a winding radiating fin, an air duct used for ventilation is formed between the lower end and the upper end of the winding radiating fin, a plurality of LED lights are arranged at the lower end of the winding radiating fin, the winding radiating fin is vertically arranged in a radiating tube, and the radiating tube is hollow and through up and down to form the air duct. The radiating tube and the outer layer of the winding radiating fin are in slidable connection, the winding radiating fin is driven by a motor to make up-and-down reciprocating movement around the common axis of the radiating tube and the winding radiating fin, and the LED lights are arranged on the peripheral wall of the lower end of the radiating tube.
Description
Technical field
The invention belongs to lighting technical field, particularly relate to a kind of LED lamp with radiator structure.
Background technology
LED because have plurality of advantages as: light efficiency is high, color is abundant, the life-span is long, solid state device, solid and reliable etc., so develop very fast.At present, as illumination, also there are some problems in LED.Be mainly that heat dispersion is poor, cause the junction temperature of LED luminescent device to raise, luminosity declines, and luminous efficiency reduces.Tracing it to its cause, is mainly because the design of existing LED lamp is all the Design Mode in accordance with conventional lamp substantially, and light source is sealed among lampshade.Traditional electrical light source resistance to elevated temperatures is good, and closed light fixture design can not affect its luminescent properties, and LED is semiconductor devices, and after its junction temperature exceedes certain value, its performance will significantly worsen.
Summary of the invention
?the object of this invention is to provide a kind of LED light fixture, brand-new design heat spreader structures, radiating effect is better.
To achieve the above object, the present invention has adopted following technical scheme: a kind of LED light fixture, comprise LED lamp and radiator, described radiator comprises takeup type fin, between takeup type fin lower end and upper end, be formed for the air channel of circulation of air, the lower end of takeup type fin arranges several LED lamps, wherein, described takeup type fin is vertically arranged in a heat-dissipating cylinder, thereby described heat-dissipating cylinder hollow up/down perforation form described air channel, described heat-dissipating cylinder is slidably connected with the skin of takeup type fin, takeup type fin is driven and is pumped around the common axis line of heat-dissipating cylinder and takeup type fin by motor, described LED lamp is arranged on the periphery wall of heat-dissipating cylinder lower end.

Brief description of the drawings
?fig. 1 is the structural representation of LED lamp of the present invention.
?fig. 2 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
?below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
?
A kind of LED light fixture as shown in Figure 1 and Figure 2, comprises LED lamp 1 and radiator, and described radiator comprises takeup type fin 2, is formed for the air channel of circulation of air between takeup type fin 2 lower ends and upper end, and the lower end of takeup type fin 2 arranges 4 LED lamps 1.Described takeup type fin 2 is vertically arranged in a heat-dissipating cylinder 5, thereby described heat-dissipating cylinder 5 hollows up/down perforation form described air channel, and described LED lamp 1 is arranged on the periphery wall of heat-dissipating cylinder 5 lower ends.
; Above-mentioned takeup type fin 2 or heat-dissipating cylinder 5 surfaces can be provided with concaveconvex structure to increase heat radiation; Described heat-dissipating cylinder 5 is slidably connected with the skin of takeup type fin 2, takeup type fin 2 is pumped around the common axis line D of heat-dissipating cylinder 5 and takeup type fin 2 by motor (not shown) edge, accelerate the circulation of heat-dissipating cylinder 5 interior air, reach good radiating effect; Described LED lamp 1 is arranged on aluminium base 6, and described aluminium base 6 welds with heat-dissipating cylinder 5; Described aluminium base 6 is provided with transparent cover plate or the lens of LED lamp 1, transparent cover plate or lens can be relatively each independently LED lamp also can be for whole LED lamps (circularizing) on whole assembly; Above-mentioned heat-dissipating cylinder 5 and takeup type fin 2 are aluminium or aluminum alloy material.
