Description
Technical field
The utility model relates to LED lamp accessory, particularly relates to a kind of heat radiation external member of LED lamp.
Background technology
LED and semiconductor light-emitting-diode, be a kind of solid-state semiconductor devices, it directly can be converted into light electricity.LED electricity-saving lamp is that light efficiency is high, little power consumption with high brightness white light-emitting diode light emitting source, life-span long, easy to control, non-maintaining, safety and environmental protection; Be solid cold light source of new generation, photochromic soft, gorgeous, rich and varied, low-loss, low energy consumption, environmental protection, be suitable for family, market, bank, hospital, hotel, throws light on other various public places for a long time in restaurant.Without dodging direct current, playing a very good protection to eyes, is desk lamp, the optimal selection of torch.In view of the above-mentioned advantage of LED lamp, it meets the demand of modern society for economize energy, environmental protection etc., is in and progressively replaces in the road for development of conventional incandescent.
Operationally, the electric energy conversion having about 80% has become heat energy to LED, and the electric energy conversion of 20% is luminous energy, therefore, for ensureing the normal work of LED lamp, needs radiator to dispel the heat in time.But, the problem that existing radiator ubiquity radiating effect is not good; Further, existing LED lamp many employings heat dispersion preferably aluminum material dispels the heat, and cause LED lamp overall weight comparatively large, transport inconvenience, and aluminum material is relatively costly, is unfavorable for controlling cost.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the heat radiation external member providing a kind of LED lamp, and it is beneficial to production control cost, and has preferably heat dispersion.
For achieving the above object, the utility model adopts following technical scheme:
Comprise screw socket, plastic feet and mould alclad radiator, described plastic feet thread bush is connected to screw socket top, described in mould alclad radiator fixedly sleeved outside plastic feet; Mould on alclad radiator and offer punched-type engraved structure.
Further, described in mould alclad radiator be horn-like, and its cross section near screw socket one end is less than its cross section away from screw socket one end.
Preferably, described punched-type engraved structure is along the circumferencial direction moulding alclad radiator several bar holes spaced, and these several bar holes are positioned at moulds alclad radiator one end away from screw socket.
Further, the heat radiation external member of this LED lamp also comprises a lampshade, and this lampshade is located at and is moulded alclad radiator one end away from screw socket.
Preferably, described lampshade with mould alclad radiator and be sticked together.
Compared to prior art, the beneficial effect that the utility model brings is:
Of the present utility model moulding on alclad radiator adopts punched-type engraved structure, LED lamp can be made more easily to complete cross-ventilation in the course of the work, reach the object of heat radiation performance; In addition, the aluminum material that radiator uses reduces relatively, is not affecting on the basis of heat dispersion, is reaching the object of production control cost better, owing to employing a large amount of light plastic in product, can reach the object reducing product weight, be easy to transport.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Refer to Fig. 1 and Fig. 2, the utility model discloses a kind of heat radiation external member of LED lamp, and it comprises screw socket 1, plastic feet 2, moulds alclad radiator 3 and lampshade 4.
Incorporated by reference to consulting Fig. 3 to Fig. 5, described screw socket 1 is provided with the installing hole (not indicating in figure) for installing LED, and the lateral wall of screw lamp holder 1 is provided with cap screw thread; Cylindrically, plastic feet 2 thread bush is connected to screw socket 1 top to described plastic feet 2, and the bottom outer wall of this plastic feet 2 is provided with a circle flange 21; Described alclad radiator 3 of moulding is in horn-like, and its cross section near screw socket 1 one end is less than its cross section away from screw socket 1 one end, during assembling, this is moulded alclad radiator 3 and is socketed on outside plastic feet 2, the bottom face moulding alclad radiator 3 is made to be connected on the top end face of flange 21, and undertaken fastening by two screw (not shown), guarantee to mould the steadiness between alclad radiator 3 and plastic feet 2; Mould alclad radiator 3 top and be provided with a dividing plate 31, mould on alclad radiator 3 and offer punched-type engraved structure, particularly, this punched-type engraved structure is along the circumferencial direction moulding alclad radiator 3 several bar holes 32 spaced, each bar hole 32 all runs through the sidewall and dividing plate 31 of moulding alclad radiator 3, and these several bar hole 32 entirety are positioned at moulds alclad radiator 3 one end away from screw socket 1; Operationally, this some bar hole 32 is closer near LED luminous site, and radiator hot inside air can form convection current via these bar holes 32 with outside air, is beneficial to distributing rapidly of heat.
Described lampshade 4 covers at moulds alclad radiator 3 one end away from screw socket 1, and this lampshade 4 adopts high transmission rate plastic material to obtain, and in order to guarantee the permeability of light, plays the effect comprising LED simultaneously; The feather edge of lampshade 4 be fastened in mould alclad radiator 3 top edge on, preferably, occur to prevent lampshade 4 loosening phenomenon, described lampshade 4 with mould alclad radiator 3 and be also fixed by gluing process; Understandable, lampshade 4 with mould the adhesion mode that alclad radiator 3 also can adopt other.
Compared to prior art, the beneficial effect that the utility model brings is:
Of the present utility model moulding on alclad radiator 3 adopts punched-type engraved structure, LED lamp can be made more easily to complete cross-ventilation in the course of the work, reach the object of heat radiation performance; In addition, mould the aluminum material that alclad radiator 3 uses relatively to reduce, do not affecting on the basis of heat dispersion, reaching the object of production control cost better, owing to employing a large amount of light plastic in product, thus reach the object reducing product weight, be easy to transport.
With being worth mentioning, punched-type engraved structure of the present utility model is not limited to the bar hole 32 of above-described embodiment, can also be the pore structure of other geometries.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
