Description
Technical field
The utility model relates to Design of Luminaires field, particularly relates to the LED bulb that a kind of thermal diffusivity is good.
Background technology
Different from common incandescent lamp, LED relies on the electronics in heterojunction semiconductor to move more direct luminescence by the energy that potential barrier produces.LED does not produce heat due to luminescence process, and energy conversion efficiency is close to absolutely, and overlong service life is the developing direction of lighting engineering from now on.
Common incandescent lamp caloric value is large, and surface temperature is high, and improper long-time illumination uses.Although LED luminescence process does not produce heat, safe to use, good energy saving property, but the circuit board of carrying LED still can produce certain heat, if use long-time continuously, circuit board is easily overheated and reduce service life, needs to improve the structure of LED bulb.
Utility model content
The technical problem that the utility model mainly solves is to provide the good LED bulb of a kind of thermal diffusivity, improves heat dispersion, longer service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide the LED bulb that a kind of thermal diffusivity is good, comprise: screw joint, connection fixing base, circuit board and LED lamp, described screw joint is arranged on the top of connection fixing base, described circuit board is arranged among connection fixing base, linearly connected is adopted between described LED lamp and circuit board, described connection fixing base bottom is provided with a heat dissipating housing, described heat dissipating housing is reducing aluminium alloy cylindrical body, described LED lamp is arranged among heat dissipating housing, the bottom of described heat dissipating housing is provided with one block of nonwoven plain cotton fabric, the surrounding of described connection fixing base is provided with several venthole.
In the utility model preferred embodiment, between described screw joint and circuit board, adopt linearly connected.
In the utility model preferred embodiment, the open top of described heat dissipating housing is less than bottom opening.
In the utility model preferred embodiment, described nonwoven plain cotton fabric is translucent non-woven fabric piece.
The beneficial effects of the utility model are: the LED bulb that a kind of thermal diffusivity of pointing out of the utility model is good, the heat that circuit board produces is discharged fast by several venthole, and fresh air supplements from the nonwoven plain cotton fabric of bottom, perfect heat-dissipating, and nonwoven plain cotton fabric avoids entering of dust, keep inner cleaning, increase the service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of LED bulb one preferred embodiment that a kind of thermal diffusivity of the utility model is good.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
The LED bulb that a kind of thermal diffusivity is good, comprise: screw joint 1, connection fixing base 2, circuit board 3 and LED lamp 4, described screw joint 1 is arranged on the top of connection fixing base 2, described circuit board 3 is arranged among connection fixing base 2, linearly connected is adopted between described LED lamp 4 and circuit board 3, described connection fixing base 2 bottom is provided with a heat dissipating housing 5, described heat dissipating housing 5 is reducing aluminium alloy cylindrical body, the thermal conductivity of aluminum alloy material is good, and itself there is the ability of certain reflection ray, improve bulb brightness, described LED lamp 4 is arranged among heat dissipating housing 5, the bottom of described heat dissipating housing 5 is provided with one block of nonwoven plain cotton fabric 6, the surrounding of described connection fixing base 2 is provided with several venthole 21.The heat that circuit board 3 produces is discharged fast by several venthole 21, and fresh air supplements from nonwoven plain cotton fabric 6 importing of bottom, improves heat dispersion.
The LED bulb that described thermal diffusivity is good is the improvement carried out on the basis of common screw socket incandescent lamp, adopts linearly connected between described screw joint 1 and circuit board 3.Screw joint 1 connects the both positive and negative polarity of external power source respectively, and be supplied to circuit board 3 voltage, and circuit board 3 is the normal voltage that applicable LED lamp 4 works voltage transitions, during work, the electric current on circuit board 3 is more concentrated, easily produces heat, therefore needs heat radiation.
Further, the open top of described heat dissipating housing 5 is less than bottom opening, guarantees the outside propagation of light and the air inflow of bottom.
Further, described nonwoven plain cotton fabric 6 is translucent non-woven fabric piece.LED lamp 4 comprises several spot light, and by refraction and the reflection of non-woven fabric piece, what external table revealed is area source, and uniformity is good, no longer dazzling.And nonwoven plain cotton fabric avoids entering of dust, keep inner cleaning, extend the service life of circuit board 3 and LED lamp 4.
In sum, the LED bulb that a kind of thermal diffusivity of pointing out of the utility model is good, compared with common LED bulb, heat dispersion is better, longer service life.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
