Abstract

A base assembly for LEDs has a top, a bottom and multiple LED recesses formed in the top and including at least one oblique LED recess and at least one perpendicular LED recess. Each oblique LED recess has an inclined bottom, an oblique sidewall and a pair of lead passages. The at least one perpendicular LED recess has a bottom parallel to the base. LEDs can be mounted respectively in the at least one oblique LED recess at an angle relative to the base and mounted upright in the perpendicular LED recess to emit lights in different directions to provide a wide-angle luminance effect. The cover is detachably mounted on the base and has at least one though hole and at least one mounting hole to allow the LEDs mounted in the LED recesses to protrude from and to be securely and exactly held in the base.

Claims

1. A base assembly for LEDs being mounted on a circuit board, the base assembly comprising

a base being adapted to be mounted on the circuit board and having a top;

a bottom;

an outside; and

multiple LED recesses being formed in the top of the base and including

at least one oblique LED recess, and each one of the at least one oblique LED recess having

a bottom being inclined relatively to the bottom of the base;

an oblique sidewall being formed adjacent and relative to the bottom of the oblique LED recess at a specific inclined angle; and

a pair of lead passages formed through the bottom of the oblique LED recess, communicating with the bottom of the base; and

at least one perpendicular LED recess, and each one of the at least one perpendicular LED recess having

a bottom being parallel to the bottom of the base; and

a pair of lead passages being formed through the bottom of the perpendicular LED recess, communicating with the bottom of the base; and

a cover being mounted detachably on the top of the base and having

an outer edge;

at least one though hole being formed through the cover and aligning respectively with the at least one perpendicular LED hole;

at least one mounting hole being formed though the cover and aligning respectively with the at least one oblique LED hole and each one of the at least one mounting hole having an edge; and

at least one inclined sidewall being formed on and protruding out from each edge of the at least one mounting hole and each inclined sidewall having

an end surface; and

an opening being formed through the end surface of the inclined sidewall.

2. The base assembly as claimed in claim 1, wherein

the at least one oblique LED recess is formed near the outside of the base;

and

the specific inclined angle of the oblique sidewall of each one of the at least one oblique LED recess tilts toward the outside of the base.

3. The base assembly as claimed in claim 1, wherein

the base further has multiple detents formed on and protruding from the outside of the base;

and

the cover further has multiple mounting tabs formed on and protruding down from the outer edge of the cover and corresponding respectively to and selectively engaging the detents on the base.

4. The base assembly as claimed in claim 1, wherein the base is rectangular.

5. The base assembly as claimed in claim 1, wherein the base is I-shaped.

6. The base assembly as claimed in claim 1, wherein the base is H-shaped.
