Abstract
Abstract A light emitting diode lamp comprises an insulated metallic board having a plurality of hollows thereon each of which has a light emitting diode mounted on the bottom thereof and a light-reflecting surface on the side wall thereof. A lens plate collects direct light from the light emitting diode and light reflected by the reflecting surfaces of each of the hollows. The lamp is suited as an automobile lamp, especially as a high mounted stop lamp.

Independent Claim
70 words
A light emitting diode lamp comprising: an insulated metallic board having a plurality of hollows thereon, each of said hollows has a light emitting diode mounted on a bottom surface thereof and each of said hollows has a light-reflecting surface on a side wall thereof; and a lens plate collects direct light from each light emitting diode and collects light reflected by the light-reflecting surfaces of each of the hollows.
Claim 2
Dependent Claim
70 words
A light emitting diode lamp comprising: an insulated metallic board having a plurality of hollows thereon, each of said hollows has a light emitting diode mounted on a bottom surface thereof and each of said hollows has a light-reflecting surface on a side wall thereof; and a lens plate collects direct light from each light emitting diode and collects light reflected by the light-reflecting surfaces of each of the hollows.
Claim 3
Dependent Claim
22 words
A light emitting diode lamp as defined in claim 1, wherein the hollows on the insulated metallic board are formed by drawing.
Claim 4
Dependent Claim
31 words
A light emitting diode lamp as defined in claim 2, wherein the insulated metallic board has other hollows on its surface, the hollows being formed by drawing and accomodating bonding wires.
Claim 5
Dependent Claim
22 words
A light emitting diode lamp as defined in claim 1, wherein at least one side of the insulated metallic board is bent.
Claim 6
Dependent Claim
43 words
A light emitting diode lamp as defined in claim 4, wherein the insulated metallic board has at least two surface regions, and a group of light emitting diodes and a group of non-light emittable parts are separately mounted on each surface region, respectively.
Claim 7
Dependent Claim
45 words
A light emitting diode lamp as defined in claim 1, wherein the insulated metallic board and/or the lens plate are provided with guide pins and/or guide holes, and the insulated metallic board and lens plate are mutually connected by the guide pins and guide holes.
Claim 8
Dependent Claim
64 words
A light emitting diode lamp as defined in claim 1, wherein the lens plate is integrated with a transparent organic polymer layer masking a surface of the insulated metallic board, and said lens plate is formed by a transparent organic polymer, an integrated body of the lens plate and the transparent organic polymer layer is set on a surface of the insulated metallic board.
