Technical Field
[0001] The present invention relates to the technical field of LED lamp manufacturing, more
particularly to an LED lamp combined three-dimensional radiating structure with full
use of radiating space.
Background
[0002] With the growing popularity of LED lamps, they have become indispensable in either
large-scale outdoor exhibition or household lighting, however, their brightness usually
couldn't reach the level of traditional lamps because their reliability is affected
by radiating problem negatively, therefore, they fail to take the place of traditional
lamps directly, for example, a 50W halogen lamp is capable of outputting 270K 610LM
luminous flux in warm white, whereas an MR16 LED with the same power can only realize
half of the brightness of traditional halogen lamps in general; a traditional 150W
PAR38 halogen lamp is capable of outputting 2700K 2000LM luminous flux in warm white,
but an LED PAR38 lamp typically outputs luminous flux that is not more than 1000LM.
[0003] The radiating bodies of a conventional LED lamp are integrally structured owing to
the problem of machining process, for example, an aluminum extrusion and aluminum
casting process is adopted; the central internal space of this lamp is a solid structure
under the limitation of the integral structure, so it is not utilized, besides, this
central internal space of the LED lamp is a space with the most concentrated heat,
thus permeability in three directions X, Y and Z cannot be realized owing to the integral
radiating structure, and the radiating bodies block each other to lead to low cold-heat
exchange efficiency between radiating surfaces and cold air, insufficient use of radiating
space and inferior radiating effect, as a result, this conventional LED lamp cannot
take the place of traditional lamps directly. For example, China Patent
201030281472.1 discloses an LED lamp radiator having an integral shape of inverted pot and achieving
radiating action by means of peripheral ridge-shaped clearances, but its machining
process is the technology of integral molding, which could result in the above defect.
[0004] Although a structurally-split radiating lamp casing is disclosed in this China Patent
201030281472.1, this casing has a radiating component inside that is composed of a radiating ring
and radiating ribs having rugged surfaces and vertically fixed on the radiating ring,
and the radiating rib is structurally formed by three rectangle-like radiating plates
having rugged surfaces and spaced apart from each other by 120 degrees based on a
vertical axis as center, in this case, only longitudinal radiation is accomplished,
airtightness still remains in the horizontal direction.

Detailed Description of the Embodiments
[0025] The present invention will be further described below with reference to the accompanying
drawings, and for those skilled in this art, its shape and structure are implementable.
[0026] A traditional MR16LED lamp is obtained by connecting and installing the following
components in a way as shown in Figure 4: either an external radiator or an internal
radiator (a radiating cup 17 is adopted in this embodiment), a lens 18, an LED display
panel 19 and a lamp interface and power supply box 20, the radiating part of the traditional
MR16LED lamp, as shown in Figure 5, is that the radiating cup 17 is equidistantly
surrounded by fan-shaped radiating fins, thus forming a radiating area as below: (radiating
surface 21+radiating surface 22+radiating surface 23+radiating surface 24+radiating
surface 25)*18=6500 square millimeters, and the interior of a traditional radiator,
as shown in Figure 6, is solid or is a cavity for placing power supply, and thus cannot
be used, in this case, uneven radiation of the traditional radiator is caused.
[0027] To thoroughly solve the radiating problem in traditional LED lamps, a unique radiating
structure is designed in the present invention, i.e. a combined three-dimensional
radiating structure.
[0028] This radiating structure is specifically constructed as shown in Figure 2 and consists
of an internal radiating body 2 and one or more radiating cups 1, the whole external
shape of the radiating cup 1 is like an inverted pot, a circular through hole is formed
by digging at the center of the circular horizontal surface on the top of the radiating
cup 1 and has a diameter consistent with the inner diameter of a cylindrical hollow
radiating fin at the center of the internal radiating body 2, two circular through
holes with equal diameter are formed by digging at the bilateral symmetry positions
of this circular through hole, and these two circular through holes have diameters
consistent with the inner diameters of two symmetrical cylindrical hollow radiating
fins at the corresponding positions inside the internal radiating body 2, and four
vertical projection surfaces are formed as round-cornered and rectangular vent grooves
6 by digging at the quarterline of the circular horizontal surface on the top of the
radiating cup.
[0029] The internal structure of the internal radiating body 2 is mainly composed of discontinuous
multilayer three-dimensional radiating fins, a cylindrical hollow radiating fin 14
is disposed on the center of a disc-shaped base, two cylindrical hollow radiating
fins with equal inner and outer diameters are installed respectively at the bilateral
symmetry positions of this cylindrical hollow radiating fin 14, two layers of discontinuous
circular-arc radiating fins 12 and 13 are distributed from inside to outside on the
quarterline of the disc-shaped base in case that the central cylindrical hollow radiating
fin 14 is regarded as reference, hollow cavities are formed between the circular-arc
radiating fins at the inner layer and the circular-arc radiating fins at the outer
layer, and connection lines between the two ends of the circular-arc radiating fin
at the inner layer and the circle center of the central cylindrical hollow radiating
fin 14 as well as connection lines between the two ends of the circular-arc radiating
fin at the outer layer and the circle center of the central cylindrical hollow radiating
fin 14 form a fan shape, and four vertical projection surfaces are formed by digging
at positions to which four circular-arc radiating fins at the outer layer are adjacent
in an outward direction, so as to serve as LED display panel vent grooves 8, in this
way, sufficient exchange between heat of the internal radiator and external cold air
is facilitated.
[0030] The number and shape of the radiating fins of the internal radiating body and the
spacing therebetween can be determined based on the space of a specific lamp; the
number and size of the radiating cup can be determined as required by the specific
lamp shape, and the radiating cup consists of one or more than two radiating bodies.
The obtainable radiating area in this embodiment is that: radiating surface 12*8+radiating
surface 13*8+radiating surface 14+radiating surface 15+raditing 16*8=15000 square
millimeters; double-surface radiating effect can be realized in one radiating body
owing to the three-dimensional radiating structure, so double surfaces of radiating
area, i.e. front and back surfaces, are calculated.
[0031] The external radiating cup 1, the internal radiating body 2, the lens 3, the LED
display panel 4 and the lamp interface and power supply box 5 are connected in a way
as shown in Figure 1, specifically, the radiating cup 1 is sleeved above the internal
radiating body 2, the top of the external radiating cup 1 is connected with the lamp
interface and power supply box 5, the bottom of the internal radiating body 1 is connected
with the LED display panel 4, and the lens 3 is installed at the bottom of the LED
display panel 4, in this way, an LED lamp as shown in Figure 3 is obtained.
[0032] As shown in Figure 3, a hollow cavity is formed between the internal radiating body
2 and the lamp interface and power supply box 5 to facilitate sufficient exchange
between heat of the internal radiator and cold air, which not only improves the permeability
of the radiating structure, but also protects power supply portion from overheating
to further prolong the life of power supply.
[0033] The present invention further comprises a radiating method with full use of luminous
bulb space for LED bulb lamp and a device thereof, as shown in Figure 7.
[0034] The method for such an LED bulb lamp is specifically as follows: the whole bulb luminous
body of the LED bulb lamp is divided into a plurality of independent luminous bodies
with hollow cavities therebetween, and the entire bulb space is opened, in this way,
