The utility model content

The utility model provides a kind of thermal diffusivity good LED lamp socket to the deficiency that exists in the above-mentioned prior art, and this lamp socket inner hollow is provided with a ventilating duct, has improved radiating effect.

The technical scheme of the utility model is achieved in that

The lamp socket that is used for the LED lamp is provided with the led light source installation site on the lamp socket sidewall, lamp socket is both ends open and in lamp socket, be provided with the ventilating duct of the whole lamp socket of up/down perforation up and down.

As preferably, described lamp socket outer contour shape is any shape in polyhedron, cylinder or the Rotary-table.Lamp socket adopts above-mentioned three-dimensional shape, can enlarge the lighting angle of whole lamp, reaches the illuminating effect that is similar to incandescent lamp.

As preferably, described lamp socket outer contour shape is a prismoid, on each side of lamp socket, is fixed with a substrate, on substrate, is fixed with led light source.

For the heat that further LED is conducted to lamp socket dispels the heat,, in the ventilating duct of lamp socket, be provided with the interior fin of longitudinally arranging as preferably.

Adopted the design philosophy and the beneficial effect of the utility model of technique scheme to be:

The lamp socket of the utility model is an assembly of LED lamp, and the utility model is to be provided with a ventilating duct in the lamp socket inner hollow, and the heat that makes led light source conduct to lamp socket can outwards dispel the heat through ventilating duct, has improved the radiating effect of lamp socket.

Further; When concrete the application, can promptly between driving power housing and heat radiation Lamp cup inwall, leave the space that forms air flow channel at the lamp body set inside air flow channel of LED lamp; And be provided with the ventilating duct of up/down perforation lamp socket in the lamp socket; Described space and ventilating duct keep air communication, and bottom, space and ventilating duct top all are communicated with outside air, make the air entering can take away the heat of driving power and led light source generation; Not only reduce the environment temperature of power work, guaranteed its service life; Can also improve the radiating effect of lamp socket, guarantee the service life of led light source.

The specific embodiment

The specific embodiment of the utility model is following:

Embodiment: the LED lamp of a kind of convenient heat radiation of present embodiment; Shown in Fig. 1～4, comprise lamp holder 1, heat radiation Lamp cup 2, driving power housing 3 and cell-shell 4, described heat radiation Lamp cup 2 inside are hollow structure; Heat radiation Lamp cup 2 connects together with driving power housing 3; Driving power 5 is installed in driving power housing 3, is provided with lid 20, circumferentially be distributed with the outer fin 12 of a plurality of vertical settings in the periphery upper edge of heat radiation Lamp cup 2 in driving power housing 3 upper lid; Leave the space 6 of ventilation between described driving power housing 3 and heat radiation Lamp cup 2 inwalls.

Described space 6 is to form like this; The external diameter of driving power housing 3 is less than the internal diameter of heat radiation Lamp cup 2; Be circumferentially with 3 in driving power housing 3 sidewall upper edges housing carried out spacing convex tendon 7; Described convex tendon 7 offsets with heat radiation Lamp cup 2 inwalls, and being arranged so that of convex tendon 7 kept fixing spacing between driving power housing and Lamp cup inwall; Install and fix for ease simultaneously, be provided with screw at convex tendon 7 tops, convex tendon 7 and heat radiation Lamp cup 2 link to each other through screw, thereby the driving power housing 3 and the Lamp cup 2 that dispels the heat are linked together.

For increasing the lighting angle of whole lamp, be provided with the lamp socket 8 that exceeds the Lamp cup upper surface on heat radiation Lamp cup 2 tops, lamp socket 8 sidewalls are provided with substrate; Be fixed with led light source on the substrate; Specifically, described lamp socket 8 outer contour shapes are the prismoid shape, on each side of lamp socket 8, are fixed with the substrate 9 of an aluminum; On substrate 9, be fixed with one group of led light source 10, substrate 9 and lamp socket 8 link to each other through screw.The lighting angle of whole lamp is about 300 degree thus, can reach the standard of Energy Star, and 180 degree more luminous than traditional LED lamp are compared has bigger coverage rate, and almost the angle with incandescent lamp is consistent.

Lamp socket 8 also is a hollow structure, in lamp socket 8, is provided with the ventilating duct 11 of the whole lamp socket of up/down perforation, in the ventilating duct 11 of lamp socket 8, is provided with the interior fin of longitudinally arranging 13.

Be provided with circular perforate 14 at cell-shell 4 tops, in perforate 14, be arranged with annular ring 15, in annular ring 15, be provided with cowling 16, cowling 16 is provided with a plurality of air vents 17, and the top of ventilating duct 11 keeps being communicated with through air vent 17 and outside air.

On the periphery of driving power housing 3 bottoms, be fixed with dispel the heat that Lamp cup 2 bottoms offset accept ring 18; Accept the ring 18 upper edges be circumferentially with a plurality of holes 19 that outside air and 6 bottoms, described space are maintained the circulation of air; Driving power housing 3 is processed by heat-conducting plastic, effectively distribute heat.

6 tops, said space and ventilating duct 11 bottoms keep air communication, therefore constitute the interior heat radiation air flow channel of whole lamp; As shown in Figure 5; When light fixture is worked; The heat that driving power 5 produces distributes in space 6, and the heat part that led light source 10 produces is distributed in the ventilating duct of lamp socket through the interior fin 13 of lamp socket 8, and another part heat distributes through the outer fin 12 that lamp socket conducts to the heat radiation Lamp cup; Shown in the direction of arrow among Fig. 5, air stream gets into from air vent, 6 the bottom discharge from the space again of the ventilating duct 11 of flowing through, space 6, thus the heat in ventilating duct, the space is taken away; The heat of the outer fin 12 of heat radiation Lamp cup is then loose by natural convection air, and air direct is shown in the direction of arrow among Fig. 5.

The inside and outside heat radiation of whole lamp combines, and has not only reduced the environment temperature of power work, has guaranteed its service life; The heat that also to greatest extent led light source is produced to the greatest extent looses, and effectively reduces the temperature of Lamp cup shell, protects people's both hands not scalded more.

In addition, all right built-in fans of the LED lamp of the utility model further promotes radiating effect.
