Description

Street lamp

Technical field

The relevant a kind of street lamp of the utility model refers to that especially a kind of preferable thermal convection current path that utilizes is to promote the lamp post structure of radiating effect.

Background technology

The structure of known street lamp is the bending external part winding hollow lamp housing of upright lamp stand, and hollow lamp housing inside is provided with lighting source, and sees 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, so use high power, large-sized lighting source mostly, as illuminators such as incandescent lamp bulb, mercury vapor lamps, but illumination efficiency is relatively poor, make the electric energy consume serious, this energy short of money day by day and precious in, the choosing in real non-a period of time, and the heat that is produced when high power, large-sized lighting source start, be difficult to dispel 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 white flag bulb future successively so in the energy-conservation subject under discussion in whole world day, light emitting diode (LED) is held its high efficiency under the arm, advantage energy-conservation and adjustable optical activity 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 at present,, therefore adopt high-power light emitting diode usually as light emitting source because street lamp needs higher light illumination as lighting use, by applying higher electric current on light emitting diode, obtained higher light illumination; Yet when light luminance and illumination improve, unavoidablely improved the heat that it produced.If in real time the heat of its generation is not 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 may 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 the electronic equipment lost of life, particularly electronic material such as battery, Control Component that lamp stand inside is placed, whether this battery normally then directly has influence on the power source of street lamp, and whether Control Component is concerning then normally whether street lamp can normal operation.
