Fig. 4~Fig. 6 is referred to, Fig. 4 is a kind of Surface-mount LED lamp 10 provided in an embodiment of the present invention.For the ease of viewing, figure
5 and Fig. 6 is the structural representation that attachment part is only set in a side of Surface-mount LED lamp.The Surface-mount LED lamp 10 includes illuminating part
11st, light guide 12 and multiple attachment parts 13 of the illuminating part 11 are electrically connected to.The attachment part 13 is conductive material, electrical connection
The illuminating part 11 and circuit board 20.The attachment part 13 includes the first attachment part 131 and second and mounts part 132.It is described luminous
Part 11 mounts part 132 by the attachment part 131 and second of electrical connection first, to switch on power.It is provided with and houses in the light guide 12
Chamber 14, the host cavity 14 is housing the illuminating part 11.The light guide 12 includes top surface 121 and the bottom surface being oppositely arranged
122 and multiple sides 123 for being connected between the top surface 121 and the bottom surface 122.Multiple sides 123 around
The week side of boss of the illuminating part 11 is set, to be emitted the light that the illuminating part 11 is launched.The first attachment part 131 and described
Second attachment part 132 is respectively arranged on the side 123 opposite end close to the top surface 121 and the bottom surface 122.It is described
First attachment part 131 and it is described second attachment part 132 to be fixed to circuit board 20 so that the Surface-mount LED lamp 10 mount to
The circuit board 20.
By setting top surface 121 that the light guide 12 of Surface-mount LED lamp 10 includes being oppositely arranged, bottom surface 122 and being connected to
Multiple sides 123 between the top surface 121 and the bottom surface 122, the multiple side 123 are located at the week of the illuminating part 11
Side, to launch light.Opposite end in each side 123 is respectively provided with attachment part 13, makes any one side 123 can
On attachment to the pad of circuit board 20, to realize which side no matter Surface-mount LED lamp 10 mount, it can realize without luminous side
To limitation, so as to which the Surface-mount LED lamp 10 can be used for the different scenes such as needs top is luminous, side is luminous, bottom is luminous, increase LED
The versatility of SMD lamp 10, avoid producing the Surface-mount LED lamp 10 of a variety of different models, save the manufacturing process of Surface-mount LED lamp 10
And cost.
In the present embodiment, the area of the side 123 is more than the top surface 121 or the area of the bottom surface 122.It is described to lead
Light part 12 can be in cuboid.The side 123 of the light guide 12 is rectangle, the top surface 121 of the light guide 12 or bottom
Face 122 is square.The long side of the side 123 is much larger than the short side of the side 123, so that the light guide 12
Light-emitting area area is big, and the area without luminous top surface 121 and bottom surface 122 of the light guide 12 is small, so as to reduce described lead
The position that light part 12 occupies.
In other embodiments, the light guide 12 can also be in other polyhedrons, e.g., triangular prism, square etc.,
To meet the demand of different application environments.
