Description

LED dispels the heat Reflecting shade structure

Technical field

The relevant a kind of LED of this utility model dispels the heat Reflecting shade structure, particularly relates to be provided with between this lamp housing and reflection shield anti- Glue bar forms, and reflection shield can be directly as the radiating component of luminous body, and without using extra heat dissipation fin.

Background technology

Due to the technology constantly quickly evolution of LED in modern age (Light Emitting Diode, light-emittingdiode), and along with The brightness increase in demand of LED and package dimension are more and more less, and produced heat energy is also the highest.In order to avoid reducing LED Luminous efficiency and service life, LED is carried out the means that effective heat extraction necessitates.

Modal LED radiating mode for use finned radiator, Fig. 1 i.e. show one of which be used in as street lamp it Class commonly use LED lamp structure, be mainly provided with LED11 at lamp socket 10 inner surface, and screen in above-mentioned with a translucent cover 12 Lamp socket 10 and LED11 surface；For forming desired thermolysis, above-mentioned lamp socket 10 surface is then provided with finned radiator 13, thoroughly Cross this finned radiator 13 and LED11 is carried out heat extraction effect.

The each fin using finned radiator 13 described above all must be transmitted through such as aluminum molding, punch forming or cuts Be whittled into the most troublesome processors such as type to manufacture, overall weight bigger and relatively costly outside, assemble the relevant of light fixture After component, another finned radiator 13 assembly that light fixture component is extra need be assembled, quite inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of LED heat radiation Reflecting shade structure, and its simple in construction, handling are convenient, can Without using under known finned radiator, pass through Reflecting shade structure under assembled heat radiation and be used as LED more easily Luminous body heat abstractor.

For reaching object above, the utility model discloses a kind of LED heat radiation Reflecting shade structure, it is characterised in that comprise:

Lamp housing on one, on this, lamp housing upper end is provided with a lamp housing room and the adapter end towards side, and described upper lamp housing is provided with Hollow is internal and has a bottom edge being sized diameter；

One circuit box, is assembled in inside the described upper lamp housing hollow below above-mentioned lamp housing room, and toward outer lower side stretching One power lead；

Reflection shield once, is combined in below described upper lamp housing, and this lower reflection shield is provided with one more than above-mentioned bottom edge diameter Top plane, this top plane extends up to a bottom face being sized from top to bottom to form a radiating surface as radiating component, Described lower reflection shield top set of planes is connected to below described upper lamp housing, and retains one section of clearance distance with foregoing circuit box；And

One luminous body, is attached at the inner surface of above-mentioned lower reflection shield top plane, and this luminous body is screened with a printing opacity cover body, and Above-mentioned power lead is made to be electrically connected with through above-mentioned top plane with this luminous body.

Wherein, above-mentioned lower reflection shield extends to described bottom face with a radian big width of flaring from top to bottom.

Wherein, above-mentioned lower reflection shield is one to extend to the geometric form of described bottom face with the radian big width of flaring from top to bottom Shape is constituted.

Wherein, above-mentioned lower reflection shield is a bamboo hat shape.

By said structure, this utility model achieves following technique effect:

1, assemble convenient, widely applicable；

2, it is connected to reflection shield under the large area heat radiation of lamp housing and, as the radiating component of whole LED, not only has good Good heat sinking function, the most completely without using known fin slices radiator, no matter the most square in manufacture and assembling operation Just with fast, overall space kenel is aobvious belongs to innovation.

Detailed description of the invention

As shown in Figures 2 to 4, LED of the present utility model heat radiation Reflecting shade structure comprises lamp housing 20 on, lamp housing 20 on this Upper end is provided with a lamp housing room 21 and the adapter end 22 towards side, and described upper lamp housing 20 is provided with inside hollow, and with a little arc Spend the big width of flaring from top to bottom until one is sized the bottom edge 23 of diameter.

One circuit box 30, is assembled in inside described upper lamp housing 20 hollow below above-mentioned lamp housing room 21, and toward outer lower side One power lead 31 of stretching.

One with the lower reflection shield 40 made by heat sink material, is combined in below described upper lamp housing 20, and this lower reflection shield 40 sets Having a top plane 41 being slightly larger than above-mentioned bottom edge 23 diameter, this top plane 41 is with a bigger radian big width of flaring from top to bottom Until a bottom face 42 being sized, it is provided as radiating component forming the radiating surface of a large volume；Described lower reflection shield 40 Top plane 41 is connected to below described upper lamp housing 20, and retains one section of clearance distance with foregoing circuit box 30.In this embodiment In, above-mentioned top plane 41 is connected to the bottom edge 23 of described upper lamp housing 20, and between described upper lamp housing 20 and lower reflection shield 40 Assemble a waterproof adhesive tape 24.In this embodiment, though above-mentioned lower reflection shield 40 is set to bamboo hat shape, but with such as rectangle, pros Other geometries of shape or ellipse etc extend the large area heat dissipating housing that the big width of flaring formed from top to bottom and certainly also fall within Feasible.

One luminous body 50, is attached at above-mentioned lower reflection shield 40 and pushes up the inner surface of plane 41, and make above-mentioned power lead 31 wear Crossing above-mentioned top plane 41 to be electrically connected with this luminous body 50, this luminous body 50 also can be screened with a printing opacity cover body 51, and this is saturating Light cover body 51 and lower reflection shield 40 push up and can assemble another waterproof adhesive tape 52 between plane 41.

As shown in Figures 4 and 5, above-mentioned luminous body 50 is after energising is shinny, and produced a large amount of heat energy will be big via being formed The lower reflection shield 40 of area radiating surface dispels the heat as radiating component, it is ensured that the luminous efficiency of luminous body 50 and use longevity Life.

This utility model is due to reflection shield 40 under directly making, in this type of LED lamp, the large area heat radiation being connected to lamp housing 20 As the radiating component of whole LED, not only there is good heat sinking function, the most completely without using known fin to dispel the heat Device, no matter the most more convenient and quick in manufacture and assembling operation, overall space kenel is aobvious to be belonged to innovation and has newly-increased effect, Whence mere formality in accordance with the law proposes new patent application.
