Abstract
The utility model discloses a high-efficiency radiating light-emitting diode (LED) street lamp, which comprises a shell, a transparent lamp shade, a heat absorption copper plate, a ceramic substrate and an LED array. The upper part of the shell is provided with radiating fins and mounting holes, the transparent lamp shade is provided with a waterproof interface, the lower surface of the shell are fixedly provided with the heat absorption copper plate and the ceramic substrate in sequence, and the LED array is welded on the ceramic substrate and is connected with an external constant-current power supply via a wire passing through the waterproof interface. The LED is used as a light-emitting source, a radiator made of aluminum alloy extruded section is directly used as the shell of the LED street lamp, the ceramic substrate with high thermal conductivity is used as an LED radiating carrier, and the heat absorption copper plate is arranged between the ceramic substrate and the radiator, so that the heat sent by the LED can be radiated faster, and the accumulated heat of the LED can be reduced, thus the brightness decline of the LED can be effectively reduced, and the LED street lamp really has long service life.
Description
Technical field
The utility model relates to the LED lighting engineering, particularly a kind of high-efficiency heat radiating LED street lamp.
Background technology
Existing LED road lamp cooling mode generally adopts aluminium base to add Aluminium Radiator, and the quality of radiating effect is relevant with the thermal conductivity factor of the material that uses itself, and the high more radiating effect of thermal conductivity factor is good more, and thermal conductivity factor low heat emission effect more is more poor.Aluminium base is a kind of metal base circuit board material, its structure is divided three layers: by Copper Foil, heat conductive insulating layer and aluminum base plate are formed, the thermal conductivity factor of copper is 401W/ (m.K), the thermal conductivity factor of aluminium is 237W/ (m.K), and the heat conductive insulating layer generally to be the particular polymer that epoxy resin or ceramic dielectric are filled constitute, thermal conductivity factor is 2.2W/ (m.K), as seen there is the heat radiation bottleneck in aluminium base itself, vertically thermal conductivity factor has only 2.2W/ (m.K), the heat that can not rapidly LED be sent exports to Aluminium Radiator, the accumulation of these heats will cause the light decay of LED, influence the normal service life of LED street lamp.
Summary of the invention
The purpose of this utility model is to provide a kind of high-efficiency heat radiating LED street lamp, and it can solve prior art and exist high-power LED street lamp heat radiation bad and be directed at the problem that light decay appears in LED, and simple in structure, easy realization.
The utility model is achieved through the following technical solutions: a kind of high-efficiency heat radiating LED street lamp, comprise housing and Transparent lamp shade, and be provided with radiating fin above the housing, fixing successively heat absorption copper coin and ceramic substrate weld led array on the ceramic substrate below the housing.Described housing adopts aluminum alloy extrusion section bar, and thermal conductivity factor is 222W/ (m.K), and than die casting aluminium height, the thermal conductivity factor of die casting aluminium is about 100W/ (m.K).For guaranteeing good thermal conductivity, the substrate of fixed L ED adopts ceramic substrate, ceramic substrate is also named alumina ceramic-base copper-clad plate (DCB), be meant that Copper Foil at high temperature is bonded directly to a kind of composite base plate on aluminium oxide (AL2O3) or aluminium nitride (ALN) ceramic substrate surface, it has excellent electric insulation and high-termal conductivity, and current capacity is big, the mechanical strength height, its thermal conductivity factor reaches 24W/ (m.K), and more than 10 times, radiating effect significantly improves than aluminium base plate hight.
For further realizing the purpose of this utility model, also adopted following technical scheme: between ceramic substrate and housing (radiator), add the thick fine copper plate of 5mm, heat sink as radiator, the size of copper coin is consistent with the ceramic substrate size, heat sink for radiator, copper is compared remarkable advantages with aluminium: the thermal conductivity factor of copper is 412W/ (m.K), 237W/ (m.K) than aluminium has improved 1 times nearly, this means the cross-sectional area that same contact area is same, the heat transmission of copper is than fast many of aluminium, the heat that can send LED fast siphons away from ceramic substrate, transfers on the fin, has further strengthened radiating effect.
Good effect of the present utility model is: it with LED as light emitting source, adopt the aluminum alloy extrusion section bar radiator directly as the housing of LED street lamp, with ceramic substrate as the LED carrier that dispels the heat, and between ceramic substrate and radiator, add the heat absorption copper coin, the heat that LED is sent is derived faster, reduce the thermal accumlation of LED, thereby reduce the light decay of LED effectively, the LED street lamp is really accomplished the long-life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, a kind of high-efficiency heat radiating LED street lamp described in the utility model, comprise housing 1, Transparent lamp shade 2, heat absorption copper coin 3, ceramic substrate 4 and led array 5, its middle shell 1 top is provided with radiating fin 6 and installing hole 7, Transparent lamp shade 2 is provided with waterproof interface 8, fixing successively heat absorption copper coin 3 and ceramic substrate 4 below the housing 1, welding led array 5 on the ceramic substrate 4, led array 5 passes waterproof interface 8 by lead and is connected with the constant-current supply of outside, why constant-current supply is not located at enclosure interior or two reasons is arranged above the housing: one, also want the evolution of heat during constant-current supply work, this can increase the temperature of housing; Its two, when constant-current supply breaks down when needing maintenance, must could dismounting, and constant-current supply is installed in the terminal box of lamp stand bottom and can avoids the problems referred to above by hoistable platform.When the utility model uses, process each parts and assembling by above-mentioned requirements.
The utility model not technology contents of detailed description is known technology.
