BACKGROUND OF THE INVENTION
Technical Field
[0001] The invention generally relates to lighting apparatuses, particularly to modularized
lighting apparatuses.
Related art
[0002] Fluorescent lamps are popularly adopted as a light source. The fluorescent lamps
use a current discharging in argon to generate ultraviolet rays. The ultraviolet rays
are transformed into visible light by phosphorus coated on glass tube. When a fluorescent
lamp becomes gradually decrepit, its intensity of illumination will fade away. Also,
mercury contained in fluorescent lamps is harmful to our bodies and environment. Accordingly,
light emitting diode (LED) lighting devices have been replacing conventional fluorescent
lamps because of consideration of environmental protection and power-saving. The LEDs
have many advantages such as small volume, low power consumption, low generation of
heat, long durability and quick response.
[0003] A conventional LED lamp includes a casing, a transparent cover mounted on the casing,
a separator board between the casing and transparent cover and an LED module disposed
on the separator board. The LED module includes a circuit board a heat sink and a
plurality of LEDs. However, the LED module is fixed in the casing so that quantity
of the LED module cannot be changed. In other words, the conventional LED lamp cannot
satisfy various requirements. Manufactures of the LED lamp must provide many different
models of productions in the market. It is so uneconomical.
Document
US 2002/0196623 A1 describes a conventional LED lamp according to the preamble of claim 1.
SUMMARY OF THE INVENTION
[0004] An object of the invention is to provide a modularized lighting device which can
be variably assembled according to practical necessity.
[0005] To accomplish the above object, the lighting device of the invention includes a support
structure and a plurality of lighting modules. The support structure is a substantially
U-shaped frame whose open side is extended with a pair of rails. Each of the lighting
modules includes a heat dissipation base connecting the rails, an LED assembly mounted
on the heat dissipation base and fins fixed on the heat dissipation base. Each of
the fins is provided with an indent for accommodating the rail.
[0006] By the modularized arrangement, the quantity of the lighting modules can be varied
to become different models of productions. The models with more lighting modules can
provide higher intensity of illumination and the models with less lighting modules
can reduce power-consumption. Besides, the lighting modules are modularized and interchangeable
so that the manufacturing and inventory costs can be effectively reduced. The lighting
modules mounted on the rails also can enhance overall strength of the lamp.

DETAILED DESCRIPTION OF THE INVENTION
[0008] Please refer to FIGs. 1-4, which illustrate the modularized lighting device according
to the invention. The modularized lighting device includes a support structure 100,
a plurality of lighting modules 200, a cover 300 and a plurality of fasteners 400.
[0009] The support structure 100 includes a hollow frame 110' and a pair of rails 120, 130.
The hollow frame 110' is a substantially U-shaped frame 110. Electrical components
such as a transformer and power cord can be accommodated in the U-shaped frame 110.
The pair of rails 120, 130 separately outwards extend from the open end on the bottom
side of the U-shaped frame 110. Additionally, a plurality of grooves 140 are separately
provided at the closed end of the U-shaped frame 110 and rails 120, 130.
[0010] The lighting modules 200 are mounted on the support structure 100 in a row. Each
of the lighting modules 200 includes a heat dissipation base 210, an LED assembly
220 and fins 230.
[0011] The heat dissipation base 210 connects to the bottom of the rails 120, 130. The heat
dissipation base 210 is made of material with good thermo-conductivity, such as, but
not limited to, copper or aluminum.
[0012] The LED assembly 220 is mounted on the bottom of the heat dissipation base 210.
[0013] The LED assembly 220 is provided with a circuit board 221 mounted on the heat dissipation
base 210 and LEDs 222 mounted on the circuit board 221. A thermo-conductive media
may be applied between the circuit board 221 and heat dissipation base 210 for increase
efficiency of heat dissipation.
[0014] The fins 230 are fixed on both sides of the heat dissipation base 210 to fasten the
U-shaped frame 110 therebetween. The fins 230 are fixed on the heat dissipation base
210 by welding or integratedly forming process. The fins 230 are made of material
with good thermo-conductivity such as copper or aluminum. Each of the fins 230 is
provided with an indent 231 for accommodating one of the rails 120, 130.
[0015] The heat dissipation base 210 may additionally be fixed to the rails 120, 130 by
fasteners 400. The heat dissipation base 210 also can be positioned. The fasteners
400 may be screws or adhesive.
[0016] The cover 300 seals up one end of the U-shaped frame 110. The cover 300 is provided
with through holes 310 separately corresponding to the grooves 140. The fasteners
400 separately penetrate the through holes 310 to screw into the grooves 140 for fastening
the cover 300 on the front end of the support structure 100.
[0017] The rear ends of the rails 120, 130 are formed with extended portions 121, 131. When
the lighting modules 200 are arranged on the U-shaped frame 110 in a row, the rearmost
one of the lighting modules 200 will be blocked by the extended portions 121, 131.
And the series of lighting modules 200 are clamped between the cover 300 and the extended
portions 121, 131.
[0018] Additionally, the invention further includes a plurality of lighting modules 200'
which are the same as the lighting modules 200.
[0019] Please refer to FIGs. 5 and 6. The quantity of the lighting modules 200 may be changed
according to practical needs. In other words, the lighting modules 200 may increase
or decrease in number. The invention may serve as a street lamp.
[0020] Please refer to FIGs. 7 and 8. The lighting device of the invention may be preferably
provided with a pair of shields 500, each of which is composed of a shade 510 and
a rod 520. One side of the shade 510 is embedded into the groove 140 atop the U-shaped
frame 110. The other side of the shade 510 is supported by the rod 520 fixed on the
heat dissipation base 210. The shields 500 may prevent the fins 230 from being wetted
by rains or covered by dusts.
[0021] Please refer to FIG. 9. The invention may serve as a wash wall light. The support
structure further includes a seat 150 and a pivot 160. The U-shaped frame 110 is provided
with a pivot hole 111 for accommodating the pivot 160 so that the U-shpaed frame 110
can rotate against the seat 150.
[0022] Please refer to FIG.10. Plural series of lighting modules 200 can be parallelly arranged
in columns. The invention further includes one or more connecting boards 600 for transversely
connecting a plurality of support structure 100 and a mount 700 for transversely connecting
a plurality of seats 150.
[0023] Please refer to FIG. 11. The support structure 100 may further include a tube 170
connected to the seat 150. A hole 151 is provided in the seat 150 for accommodating
a power cord in the U-shaped frame 110.
[0024] Please refer to FIG. 12. The seat 150 may be pivotally connected to the U-shaped
frame 110. A pivot portion is disposed atop the U-shaped frame 110. The pivot hole
111 is just in the pivot portion and passed through by the pivot 160.
[0025] Please refer to FIG. 13. The invention further includes a hood 800 covering the support
structure 100, lighting modules 200 and shields 500 with exposing the LED assembly
220. In this embodiment, the pivot hole 111 is disposed in the hood 800 so that the
hood 800 can rotate against the seat 150.
