Abstract

An easy-to-assemble integrated LED bulb lamp includes a lampshade, a bulb base, a lamp cap, an LED module, a driver IC, a resistor, a lampshade and a lamp cap that form a sealed cavity. The bulb base is installed to an opening of the lampshade to divide the sealed cavity into an upper compartment and a lower compartment; the LED module is installed in the upper compartment; and the LED module is partially inserted into the bulb base and connected to the driver IC in the bulb base. Since the driver IC and the LED module can be integrally fixed during the injection molding of the bulb base, therefore the actual assembling process only requires the step of soldering the solder point of the resistor, and the assembling process can be simplified significantly to increase productivity.

Claims (21)

1. An easy-to-assemble integrated LED bulb lamp, comprising:

a lampshade;

a bulb base attached to an opening of the lampshade;

a lamp cap attached to the lampshade;

an LED module placed inside the lampshade;

a driver IC embedded inside the bulb base; and

a resistor electrically connected to the lamp cap,

wherein

the lampshade and the lamp cap form a sealed cavity, and the sealed cavity is divided into an upper compartment and a lower compartment;

the LED module is installed in the upper compartment;

the LED module is partially inserted into the bulb base and coupled to the driver IC in the bulb base;

the driver IC is further coupled to a first pin and a second pin that extend outwardly from the bulb base;

the resistor is disposed in the lower compartment and electrically coupled to the first pin;

the second pin is electrically coupled to an inner wall of the lamp cap through an electrical connecting part which is disposed in the lower compartment;

the bulb base comprises a column-shaped body, an upper boss disposed on an upper surface of the column-shaped body upper surface, and a lower boss disposed on a lower surface of the column-shaped body; and

the lower boss having a vertical length longer than length of first pin and the second pin and a width extending from one end of the lamp cap to an opposite end of the lamp cap for isolating the first pin from the second pin.

2. The easy-to-assemble integrated LED bulb lamp as claimed in claim 1 , wherein the LED module comprises a light stand, a light strip, and at least one light strip installed onto the light stand.

3. The easy-to-assemble integrated LED bulb lamp as claimed in claim 1 , wherein the upper boss is substantially in the shape of an isosceles trapezoid, and the driver IC is embedded into the upper boss.

4. The easy-to-assemble integrated LED bulb lamp as claimed in claim 1 , wherein the lower boss is substantially in the shape of a right-angled trapezoid.

5. The easy-to-assemble integrated LED bulb lamp as claimed in claim 1 , wherein the upper boss and the lower boss are staggered by 90 degrees in the radial direction with the column-shaped body as the center, and staggered substantially in a cross shape.

6. The easy-to-assemble integrated LED bulb lamp as claimed in claim 1 , wherein the electrical connecting part is substantially U-shaped, and a side of the electrical connecting part touches an inner side of the lamp cap, and the touching side is substantially bent in waves.
