Abstract

The utility model discloses an LED (Light-Emitting Diode) lamp with a heat radiation sheet, comprising a lamp holder, a lamp cover which is horizontally arranged above the lamp holder, an LED light-emitting assembly located between the lamp holder and the lamp cover, and heat radiation mechanisms arranged on the periphery of the LED light-emitting assembly, wherein each heat radiation mechanism comprises a heat radiation cylinder and heat radiation sheets which are fixedly arranged on the outer wall of the heat radiation cylinder and are distributed in a circumferential direction; a fixing ring which is concentric with the lamp cover is arranged at the outer side of the lamp cover; the top ends of the heat radiation sheets are fixedly connected with the fixing ring; and the heat radiation sheets are bent towards the same direction of the circumferential direction of the fixing ring. The LED lamp with the heat radiation sheet disclosed by the utility model has a simple whole structure; the heat radiation cylinders are provided with the heat radiation sheets, so that the heat radiation effect is good; and therefore, the service life of the LED lamp is prolonged.

Description

A kind of flange-cooled LED light fixture

Technical field

The utility model belongs to the lighting design field, specifically relates to a kind of flange-cooled LED light fixture.

Background technology

LED is the abbreviation of Light-Emitting Diode, is the solid-state light emitting element that semi-conducting material is processed.The maximum characteristics of LED light fixture are that bright lamp is fast, volume is little, shatter-proof and energy-conserving and environment-protective.But because the caloric value of led light source is big, need heat radiation to guarantee its operate as normal, existing LED light fixture generally all is that fin is set when carrying out heat dissipation design, dispels the heat through fin.For example, publication number is that the patent documentation of 102242873A discloses a kind of LED lamp, mainly comprises led module, fin and lamp socket; This led module has heat-conducting part and electrical ties portion; Fin is the good nonmetal formation of thermal diffusivity, and lamp socket becomes the lamp socket profile for the nonmetallic materials straight forming, and the portion of holding was installed with aforementioned fin in it had; The heat-conducting part of this led module combines with fin; Electrical ties portion then links external power source, and when LED lighted, the heat of its generation can be rapidly by fin institute heat loss through conduction.The fin of above-mentioned LED light fixture can be realized the effect of quick heat radiating, and is safe and convenient to use and flexible.But the fin of above-mentioned LED light fixture is a slab construction, and area of dissipation is little, and radiating effect is relatively poor.

The utility model content

The utility model provides a kind of flange-cooled LED light fixture, and the heat radiating fin structure of this light fixture is simple, band fin, good heat dissipation effect, the service life of having improved the LED light fixture.

A kind of flange-cooled LED light fixture; Comprise lampshade, the LED luminescence component between lamp socket and lampshade of lamp socket, the setting of lamp socket upper horizontal and be located at LED luminescence component cooling mechanism all around; The fin that described cooling mechanism comprises heat-dissipating cylinder and is fixed on the heat-dissipating cylinder outer wall and circumferentially distributes; The described lampshade outside is provided with the retainer plate concentric with lampshade, and described fin top and retainer plate are fixed, and fin is circumferentially crooked in the same direction along retainer plate.

Fin is crooked to be provided with, and has increased the area of dissipation of fin down identical taking up room, and has improved the heat dispersion of fin.

For ease of the processing of retainer plate and fin, a kind of optimized technical scheme is: described retainer plate and fin and heat-dissipating cylinder are for being wholely set.Retainer plate and fin and heat-dissipating cylinder can be selected LED field of light fittings heat sink material commonly used for use.

For further improving the shock resistance of the utility model LED light fixture, described lampshade week is along fixing through bolt and said fin top.Lampshade and fin top interfix, and have increased LED light fixture whole rigidity, have improved the service life of LED light fixture.

The flange-cooled LED light fixture of the utility model, overall structure is simple, heat-dissipating cylinder band fin, good heat dissipation effect, the service life of having improved the LED light fixture.

Description of drawings

Fig. 1 is the structural representation of the flange-cooled LED light fixture of the utility model;

Fig. 2 is the front view of the described LED light fixture of Fig. 1.

The specific embodiment

Lampshade 2, the LED luminescence component 5 between lamp socket 1 and lampshade 2 of lamp socket as depicted in figs. 1 and 21, lamp socket 1 upper horizontal setting and be located at the cooling mechanism around the LED luminescence component 5; The fin 3 that cooling mechanism comprises heat-dissipating cylinder and is fixed on the heat-dissipating cylinder outer wall and circumferentially distributes; Lampshade 2 outsides are provided with the retainer plate 4 concentric with lampshade 2; Fin 3 tops and retainer plate 4 are fixing, and fin 3 outsides are circumferentially crooked in the same direction along retainer plate 4.

Lamp socket 1 outside is provided with external screw thread, is convenient to the fixing of LED light fixture.LED luminescence component 5 generally comprises LED illuminating source, drive circuit board and led light source ON-OFF control circuit (omitting in the detailed structure view).

Retainer plate 4 and fin 3 and heat-dissipating cylinder are for being wholely set.During making, retainer plate 4 and fin 3 and heat-dissipating cylinder one-shot forming, manufacturing process is simple.Retainer plate 4 can be selected the conventional heat sink material in this area for use with fin 3 and heat-dissipating cylinder, like aluminium alloy etc.The size of retainer plate 4 diameters is generally confirmed according to the width and the flexibility of fin 3.The number of the width of fin 3, length and thickness and setting can be confirmed according to the size of actual LED luminescence component.Lampshade 2 outsides are fixed through bolt and fin 3 tops.

The heat that produces in the LED light fixture use in the present embodiment is passed to fin 3 through heat-dissipating cylinder, by fin 3 with heat diffusion to surrounding environment.Fin 3 crooked settings have increased the area of dissipation of fin 3, the service life that helps improving the LED light fixture greatly.
