[0034] Referring to FIGS. 1, 3, 4 and 5, the composite printed circuit board 4 is of single-layer.
The communication module 6 and the LED module 5 are welded on the composite printed
circuit board 4. That is, the communication module 6 and the LED module 5 are welded

[0035] An internal wall of the main body 1 is configured with a ring-shaped stage 131. The
composite printed circuit board 4 engages with the ring-shaped stage 131. The composite
printed circuit board 4 is a composite board made by a metal substrate and an insulating

the composite printed circuit board 4 and the conductive layer.
[0038] Referring to FIG. 3, the first sub-board 41 is embedded within the second sub-board
42 so as to form the composite substrate. As the first sub-board 41 and the second
sub-board 42 are on the same plane, the communication module 6 and the LED module
5 are also on the same plane. As all components of the communication module 6 and
the LED module 5 are on the same plane, such configuration may save space.
[0039] The first sub-board 41 and the second sub-board 42 both include the conductive layer.
The resistance line 9 is arranged in the central area of the composite printed circuit
board 4, that is, the resistance line 9 is arranged on the first sub-board 41 for
providing power supply to the communication module 6. On the other hand, the LED module
5 may operate in accordance with the signals from the communication module 6. With
such configuration, the feedback route of the signals from the communication module
6 to the LED module 5 may be easily configured.
[0040] Referring to FIGS. 4 and 5, in one embodiment, the communication module 6 and the
LED module 5 may not be on the same plane. In some embodiments, the communication
module 6 further includes an antenna 61, a radio frequency circuitry 62 coupled to
the antenna 61 for receiving wireless signals, and a radio frequency power circuitry
63 for providing power to the radio frequency circuitry 62.
[0041] Referring to FIG. 4, the radio frequency circuitry 62 and the antenna 61 may be integrated
as a module to be welded on the composite printed circuit board 4. Specifically, the
first sub-board 41 includes a first layer 411 and a second layer 412 stacked together.
The first layer 411 and the second layer 412 are on the same plane. The radio frequency
power circuitry 63 is arranged on the first layer 411, and the antenna 61 and the
radio frequency circuitry 62 are arranged on the second layer 412. That is, the radio
frequency power circuitry 63 and the LED module 5 are on the same plane. To avoid
signal interference, the second layer 412 is disposed away from the radio frequency
power circuitry 63.
[0042] Referring to FIG. 5, in another embodiment, the antenna 61 may be configured externally,
and the radio frequency circuitry 62 and the radio frequency power circuitry 63 may
be separately arranged. Specifically, the first sub-board 41 includes the first layer
411, the second layer 412, and a third layer 413. The first layer 411 and the second
sub-board 42 are on the same plane, and the radio frequency power circuitry 63 is
arranged on the first layer 411. The radio frequency circuitry 62 is arranged on the
second layer 412, and the antenna 61 is arranged on the third layer 413. The second
layer 412 is disposed away from the radio frequency power circuitry 63, and the third
layer 413 is disposed away from the radio frequency circuitry 62 and the radio frequency
power circuitry 63 so as to avoid the signals interference.
[0043] Referring to FIG. 7, in some embodiments, the radio frequency circuitry 62 further
includes a radio frequency integrated circuit 621 and an antenna impedance matching
circuitry 6214 electrically connected to the antenna 61. The radio frequency integrated
circuit 621 further includes a filter circuitry 6211, a crystal oscillator 6212 and
a flash memory 6213.
[0044] Referring to FIG. 6, in one embodiment, the filter circuitry 6211, the crystal oscillator
6212 and the flash memory 6213 may be located outside the radio frequency integrated
circuit 621.
[0045] In some embodiments, the antenna 61 is a unipolar antenna disposed on the first sub-board
41. The unipolar antenna may be a single wire only occupying very small space. In
another example, the antenna 61 may be configured to be strip-shaped or at least one
of a zigzag shape, a spiral shape, a stage shape or a ring shape according to the
shape of the first sub-substrate 41. As such, the length of the antenna 61 can be
flexibly adjusted to match different operating frequencies. The material of the antenna
61 may be at least one of gold, silver, copper, palladium, platinum, nickel, and stainless
steel. In a specific application, different materials and different shapes of the
antenna 61 may be configured according to different scenarios.
[0046] Referring to FIGS. 1-5, the LED module 5 includes at least one first LED 51 and a
driver circuitry 52. The driver circuitry 52 electrically connects to the LED 51 so
as to drive the LED 51. The driver circuitry 52 is arranged on the composite printed
circuit board 4, that is, the driver circuitry 52 and the LED 51 are circuit-fused
together. Such configuration is feasible for Driver on Board (DOB) lamp, which is
usually referred to as "de-energizing," that is, the conventional AC/DC (AC to DC)
rectifier is removed. The LED driving circuit and the LED string circuit are combined.
The DOB uses high-voltage LEDs plus a streamlined high-voltage driving circuit, which
can be directly driven by the main voltage, without the need of additional components
such as inductors, electrolytic capacitors, and transformers. As such, the size and
cost of the lamp may be reduced. In one embodiment, when there are many LEDs 51, the
LEDs 51 may be configured to surround the second sub-board 42 so as to provide uniform
light.
[0047] Referring to FIG. 8, in one embodiment, the power may be supplied to the LED 51 by
the path described below. The alternating current of the external power source reaches
the first sub-board 41 through the metal piece 7 and the resistance line 9 of the
head body 2. The alternating current is then transmitted to the second sub-board 42
through the wires on the first sub-board 41, and then supplied to the LED 51 through
the driver circuitry 52. Afterward, the alternating current is transmitted to the
main body 1 through the edge line 8, and back to the head body 2 to form a complete
circuit.
[0048] The power may be supplied to the antenna 61 by the path described below. The alternating
current of the external power source is transmitted to the first sub-board 41 via
the metal piece 7 and the resistance line 9 of the head body 2 so as to provide the
power to the radio frequency power circuitry 63. The alternating current is then supplied
to the radio frequency circuitry 62 through the radio frequency power circuitry 63.
The radio frequency circuit 62 then supplies the power to the antenna 61.
[0049] The signals may be provided to the radio frequency circuitry 62 by the path described
below. The antenna 61 receives the signals and transforms the signals into electronic
signals. The electronic signals are then transmitted to the radio frequency circuitry
62 via the wires on the first sub-board 41.
[0050] The LED module 5 may be driven by the communication module 6. In one example, the
radio frequency circuitry 62 controls the driver circuitry 52 in accordance with the
control signals so as to drive the LED 51.
[0051] The assembly process of the lamp will be described in detail below. First, the assembled
composite printed circuit board 4, the resistance line 9, and the edge line 8 are
applied with the wave soldering process. After the wave soldering process, the resistance
line 9, the edge line 8, and the composite printed circuit board 4 are fixed together
with solder paste.
[0052] Next, the resistance line 9 of the composite printed circuit board 4 is aligned with
the middle of the main body 1, and the edge line 8 is aligned with the socket 12 at
the bottom of the main body 1. The composite printed circuit board 4 is placed on
the ring-shaped stage 131 inside the main body 1, and the composite printed circuit
board 4 is riveted and connected together via the jig. The interference fit between
the two is between 0 and 0.1 mm. In a specific application, the interference gap may
be 0, 0.05 mm or 0.1 mm. After the head body 2 and the metal piece 7 are assembled,
the head body 2 is riveted to meet the requirements of the torsion and bending moment.
In this way, the head body 2 is prevented from falling off. Lastly, a ring of silicone
adhesive or the like is applied to the other end of the main body 1, and the bulb
body 3 is assembled. After the silicone glue dries, the bulb body 3 may be fixed on
the main body 1.
