Abstract

An LED bulb laterally installed and projecting light beams onto the ground includes a bulb holder assembly, a lamp carrier assembly, a luminosity module, a lampshade, a collar, and a clasper. The bulb holder assembly includes a bulb holder base and a bulb holder. The lamp carrier assembly includes a tubular column and a shell body formed on an end of the tubular column. The luminosity module is installed in the shell body and includes at least an LED. The collar is securely connected to the bulb holder base and mounted around the tubular column for development of an accommodating space between the collar and the tubular column. The clasper is closely engaged in the accommodating space and securely connected to the tubular column. The lamp carrier assembly is omni-directionally adjusted relative to the bulb holder base to make the LEDs'"'"' projecting plane face the ground surface.

Claims

1. A LED bulb laterally installed and projecting light beams onto ground comprising:

a bulb holder assembly including a bulb holder base and a bulb holder installed on a lower end of the bulb holder base, with a top opening formed in an upper end of the bulb holder base, with an actuator provided in the bulb holder base;

a lamp carrier assembly including a tubular column having a first end mounted in the top opening of the bulb holder base, with a shell body formed at a second end of the tubular column and having at least one opening for projection of light beams, with a 90-degree or 45-degree projecting angle formed between a direction of the projected light beams from the opening of the shell body and an axial direction of the tubular column;

a luminosity module installed inside the shell body and electrically connected to the actuator, with the luminosity module including at least one substrate and at least one LED on the at least one substrate;

a lampshade assembled on the opening of the shell body for transmission of the light beams out of the at least one LED;

an annular collar concentrically mounted around the first end of the tubular column and secured to the upper end of the bulb holder base, with the annular collar including an annular joining portion formed at a lower end thereof, with an annular accommodating space formed between the annular joining portion and the tubular column; and

an annular clasper rotatably received in the annular accommodating space and securely connected to the first end of the tubular column, wherein the annular clasper in the annular accommodating space is intermediate the annular collar and the bulb holder base in the axial direction, with the annular clasper and the tubular column rotatable about the axial direction relative to the bulb holder base and the annular collar, and wherein the lamp carrier assembly is adjustable relative to the bulb holder base to make a projecting plane of the at least one LED face the ground.

2. The LED bulb as claimed in claim 1, wherein the annular collar joins at the bulb holder base with threads, screws, rivets, pins or by fusion connection.

3. The LED bulb as claimed in claim 1, wherein the annular clasper joins at the tubular column with threads, screws, rivets, pins or by fusion connection.

4. The LED bulb as claimed in claim 1, wherein a plurality of knurls is formed on each of an outer surface of the bulb holder base, an outer periphery of the shell body, and an outer surface of the annular collar and extends in the axial direction of the tubular column.

5. The LED bulb as claimed in claim 1, wherein the shell body includes two opposed openings, with a 90-degree projecting angle formed between a direction of the light beams projected from each opening of the shell body and the axial direction of the tubular column, wherein the at least one substrate includes upper and lower substrates and the at least one LED comprises LEDs on an outer surface of each of the upper and lower substrates, and wherein the upper and lower substrates are installed on both flanks of a heat sink body.

6. The LED bulb as claimed in claim 5, wherein a plurality of knurls is formed on each of an outer surface of the bulb holder base, an outer periphery of the shell body, and an outer surface of the annular collar and extends in the axial direction of the tubular column.

7. The LED bulb as claimed in claim 1, wherein the shell body is a semicircular body or a transparent tubular body.

8. The LED bulb as claimed in claim 1, wherein the shell body of the lamp carrier assembly includes a semi-cylindrical base and a semi-cylindrical bulb shell covered on the semi-cylindrical base.
