Description
Technical field
This utility model belongs to LED whole lamp field, more particularly to a kind of LED whole lamp of heat radiation.
Background technology
In recent years, LED illumination industry development is rapid, and whole world output value annual rate of growth is maintained at more than 20%, public
It is considered one of 21 century high-tech sector most with prospects.Transition of world's lighting industry and emerging
The emergence of LED illumination industry, it has also become undisputable fact.Outdoor lighting is high-power photograph under the support of government
The bright market started at first, especially street lamp and Tunnel Lamp market will keep under the drive of government's demonstration project
Quickly increase.Room lighting is maximum potential market, has the most just started to start, has been mainly used in business
The commercial lighting field such as field, storage, along with the further reduction of LED illumination cost, home lighting field will
Starting extensive growth, room lighting will be the fastest market of future growth.
The whole lamp of LED is higher to the requirement of heat radiation, and the height of heat dispersion directly determines LED lamp bead and drives
The life-span length in galvanic electricity source.Traditional LED whole lamp heat radiation external member uses one piece of all lamp bead of base plate carrying.Its
Circuit compactness so that LED lamp bead group interval is the nearest, it has not been convenient to the cross-ventilation of hot-air and outside air and
Cold and hot exchange.For solve with present on problem, majority by traditional heat-dissipating external member maximize, although be solve
Determined heat dissipation problem, but also brought another one problem, i.e. volume becomes big.Both improve processing cost,
Add again transport space.
Summary of the invention
This utility model purpose is to provide a kind of whole lamp of cooling LED for solving the problems referred to above, including inside
Being provided with the LED external member driving power supply and the lamp socket being attached thereto, the whole lamp of described cooling LED also includes multiple
The substrate of carrying LED lamp bead, described substrate electrically connects with LED external member；Described substrate edge at electrical connection
LED external member end direction extends；Described LED lamp bead is arranged on the inner surface of described substrate；Described substrate by
Shape memory alloy material is made, and described basal plate heated reaches preset temperature value and can produce to away from described LED
The Bending Deformation in external member direction.
Further, the outer surface of one end that described LED external member is connected with lamp socket is provided with multiple hole, described
The bottom of LED external member also is provided with at least one hole.
Further, described LED external member is made up of pottery.
Further, described preset temperature is 40 DEG C.
Further, described substrate is made up of Nitinol.
Advantageous Effects of the present utility model:
According to the whole lamp of cooling LED described in the utility model, owing to lamp bead group is arranged on multiple substrate,
Interval between lamp bead group is bigger so that heat will not be concentrated, and reduces lamp bead group temperature, improves it and uses
Life-span.After turning on the whole lamp of LED, lamp bead produces heat, and memorial alloy substrate outwards launches after being heated, the most cruelly
Dew is in atmosphere, it is possible to effectively carries out the exchange of air, also has the effect reducing lamp bead group temperature.
After the whole lamp of LED is closed, the cooling of memorial alloy substrate recovers original state, is attached to the outer surface of the whole lamp of LED,
Make whole lamp compact, instant packed and transportation.Outside one end that the whole light kit of LED is connected with lamp socket
Surface is provided with multiple hole, and the bottom of described LED external member also is provided with at least one hole, due to stack effect,
During lamp is lighted, hot-air is discharged from top vent hole, due to the discharge of hot-air, external member internal gas pressure
Diminishing, the passage that cold air is just offered bottom external member enters external member.Thus it is effectively increased driving electricity
The thermal diffusivity in source, adds its service life.

Detailed description of the invention
In conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 and detailed description of the invention, this utility model is entered one
Step explanation.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of whole lamp of cooling LED, it is provided with driving electricity including inside
The LED external member 1 in source and the lamp socket 2 being attached thereto, the whole lamp of described cooling LED also includes multiple carrying LED
The substrate 3 of lamp bead, described substrate 3 electrically connects with LED external member 1；Described substrate 3 edge at electrical connection
LED external member 1 end direction extends；Described LED lamp bead is arranged on the inner surface of described substrate 3；Described base
Plate 3 is made up of shape memory alloy material, described substrate 3 be heated reach preset temperature value can produce to away from
The Bending Deformation in described LED external member 1 direction.
The outer surface of one end that described LED external member 1 is connected with lamp socket 2 is provided with multiple hole, described LED
The bottom of external member 1 also is provided with at least one hole.Described hole can be arranged as required to the shape in quantity and hole
Shape, the shape in hole can be circular, square, triangle etc..After the whole lamp of LED is opened, LED external member 1
In driving power work time can produce a large amount of heat energy, owing to stack effect hot-air is from external member top vent hole
Discharging, due to the discharge of hot-air, external member internal gas pressure diminishes, the ventilation that cold air is just offered bottom external member
Hole enters in external member.Thus reached to drive the heat radiation of power supply, improve the service life driving power supply.
Described memorial alloy substrate can use corronil, Nitinol, Copper-zinc alloy material, the present embodiment
Preferably employ Nitinol to constitute.Described LED external member is adopted and is made from an insulative material, and the present embodiment is preferably adopted
Make with pottery, not only there is insulating capacity and heat-resisting anti-knock properties are good, can effectively reduce electronic component and cross thermal conductance
The fire risk caused.The preset temperature that described substrate 3 deforms upon can select between 40 DEG C to 50 DEG C, excellent
Elect 40 as, can faster allow base plate deformation, it is thus achieved that illuminating effect.
The whole lamp of above-mentioned LED, owing to its substrate 3 is made up of marmem, reaches pre-when substrate 3 is heated
If during temperature, can be deformed.When substrate 3 temperature is less than preset temperature, can automatically recover original shape
Shape.In the present embodiment, the heat that LED lamp bead produces is transmitted on substrate 3, reaches after preset temperature by shape
The substrate 3 that shape memory alloys is made produces the Bending Deformation away from LED external member direction, makes substrate 3 after deformation
The one of the lamp bead that is provided with face down, be illuminated.The substrate 3 of 4 carrying LED lamp bead is disconnected from each other simultaneously,
Heat will not be concentrated in together, reduce the temperature around LED lamp bead.After closing the whole lamp of LED, base
Plate 3 starts to shrink at owing to temperature declines, and is attached to LED external member 1 surrounding by LED external member 1 and lamp socket 2
Encase, advantageously reduce the dust being attached on the whole lamp of LED.
Although specifically show and describe the present invention in conjunction with preferred embodiment, but those skilled in the art
Should be understood that in the spirit and scope of the present invention limited without departing from appended claims, in form
Above and the present invention can be made a variety of changes in details, be protection scope of the present invention.
