Abstract
The utility model discloses a strengthened heat radiation structure of a streetlamp, which takes a lamp shell base as a mechanical structure body for containing a light-emitting diode of the streetlamp and a power supply module, wherein a light-emitting diode is arranged at one side of the lamp shell seat and a shell seat section is arranged at the other side; a plurality of heat radiation channels which are arranged along the vertical direction of the shell seat section and are used for discharging waste heat out of the lamp shell seat are arranged on the region of the shell seat section, which is provided with the light-emitting diode; and the inner sides of the heat radiation channels are concave-convex surface structures. The heat radiation structure of the streetlamp gets rid of the customary smooth surface design concept and is designed into the concave-convex surface structure, so that the surface area of the heat radiation structure is further enlarged; and therefore, the contact face between the heat radiation structure and the waste heat is enlarged and the heat radiation effect is finally and obviously strengthened.
Description
Technical field
The utility model relates to a kind of holder structure of street lamp, is meant a kind of enhance heat structure of using light emitting diode as the road lamp cap of light source especially.
Background technology
The structure of known street lamp is the bending external part winding hollow lamp housing of upright lamp stand, hollow lamp housing set inside lighting source, and see through the transparent lamp shade of lamp housing bottom, so that the night illumination of road and context to be provided.Known street lamp requires high brightness, thus use high power, large-sized lighting source mostly, like illuminators such as incandescent lamp bulb, mercury vapor lamps; But illumination efficiency is relatively poor, makes electric energy consume serious, this energy short of money day by day and precious in; The heat that is produced when the choosing in non-a period of time, and high power in fact, large-sized lighting source start is difficult to dispelled the heat by housing; Cause the too high or lighting source of the temperature of housing to burn, need frequent maintain and replace, waste of manpower, material resources and time.
More ferment and national governments will forbid under the policy of incandescent lamp bulb future successively in the energy-conservation subject under discussion in whole world day; The advantage that light emitting diode (LED) is held its high efficiency, energy-conservation and adjustable optical activity under the arm forms agitation gradually in illumination market, and it has been the focus of attracting attention in the whole world in application such as street lamp, car light, outdoor lighting, situation illuminations.
However; When utilizing light emitting diode as lighting use at present, because street lamp needs higher light illumination, the light emitting diode that therefore adopts high power usually is as light emitting source; By applying higher electric current on light emitting diode, to obtain higher light illumination; Yet when light luminance and illumination improve, unavoidablely improved the heat that it produced.If untimely heat with its generation is discharged, not only cause light emitting diode to accumulate heat on every side easily, and cause the reduction of luminous efficiency, and cause light decay, more possibly influence the life-span of light emitting diode.
Moreover, because street lamp is to be installed on outdoor open space, when solar light irradiation; Because of lamp stand inside is the space of a sealing; Can make internal heat energy to discharge and temperature significantly raises, so make electronic materials such as the inner electronic equipment lost of life, particularly power supply unit of being placed of lamp stand (like battery etc.), Control Component easily; This power supply unit whether operate as normal directly has influence on the power source of street lamp, and whether Control Component is concerning then normally whether street lamp can normal operation.
The utility model content
The technical problem that the utility model solved is to provide a kind of street lamp enhance heat structure, thereby can effectively improve the waste heat discharge efficient of street lamp, strengthens the road lamp cooling effect.
The technical scheme of the utility model is:
A kind of street lamp enhance heat structure is with the frame for movement body of a lamp seat as the light emitting diode of taking in street lamp and supply module; Said lamp seat one side is equipped with light emitting diode; Opposite side is provided with the shell block section; The place, top, zone that light emitting diode is installed on the said shell block section is provided with a plurality of heat dissipation channels that are used for used heat is discharged said lamp seat that vertically dispose along said shell block section, and said heat dissipation channel inboard is rough surface texture.
Above-mentioned street lamp enhance heat structure, preferably, said rough surface texture is zigzag or convex dot shape or step structure.Certainly in this patent, the heat dissipation channel inboard can also be other various rough surface textures.
Above-mentioned street lamp enhance heat structure; Preferably; A shielding and a back shielding before said shell block section front and back ends is respectively equipped with one, said preceding shielding is provided with and the corresponding louvre of said heat dissipation channel, and the shielding of said back also is provided with and the corresponding louvre of said heat dissipation channel.
Above-mentioned street lamp enhance heat structure, preferably, said shell block Duan Zaiqi bottom surface is provided with a planar portions as the zone that supplies to install light emitting diode.
The beneficial effect of the utility model is: the street lamp enhance heat structure of this patent; The lamp seat of being made up of a lamp seat section, preceding shielding and back shielding is a main body; This lamp seat one side supplies to install light emitting diode; It focuses on, and the shell block section is provided with a plurality of heat dissipation channels along the vertical configuration of shell block section with respect to the place, top, zone that light emitting diode is installed, and such radiator structure can guide a large amount of air communication to cross lamp seat and take the used heat of light emitting diode and relevant supply module out of lamp seat; To quicken the waste heat discharge of street lamp, make street lamp be able to long-time steady operation.
In terms of existing technologies; The radiator structure of this patent street lamp is abandoned usual smooth surface design concept; It is designed to rough surface texture; Thereby further strengthen the surface area of radiator structure, the contact-making surface of radiator structure and used heat has increased like this, has finally significantly strengthened radiating effect.
The shell block section of lamp seat and heat dissipation channel thereof can be one-body molded and form an aluminium extruded stage casing by aluminium extruded in this patent, also or with forging, casting or alternate manner moulding.
Moreover shielding and back shielding were as taking in the light emitting diode of street lamp and the frame for movement body of supply module before the shell block section of lamp seat further was provided with; And be respectively equipped with and the corresponding louvre of heat dissipation channel in preceding shielding and back shielding.Like this can before and after louvre and the heat dissipation channel of shell block section of shielding can guide a large amount of air communication to cross lamp seat equally, and take the used heat that light emitting diode reaches the supply module of being correlated with out of lamp seat by air-flow through lamp seat.
