Abstract
The utility model discloses an arc LED (light emitting diode) street lamp capable of radiating efficiently, comprising an aluminum lamp body and a transparent lampshade, wherein a fixing mounting hole and heat radiating fins are arranged on the lamp body, a constant current drive power supply is fixed at the back of the fixing mounting hole, a transverse ventilation hole for radiating is arranged at the middle of the lamp body, seven fixed ceramic base plates are fixed on the lower part of the lamp body, an LED array is welded on the ceramic base plate, and a transparent lampshade is arranged at the bottom of the lamp body. The surface of each ceramic base plate fixed at the lower part of the lamp body is arc, each ceramic base plate is in a shape of a long strip, and the seven ceramic base plates are uniformly fixed on the arc surface below the lamp body. The arc LED street lamp takes an LED as a light emitting source and utilizes an arc light emitting surface so that the illumination area of the LED street lamp is larger, the road illuminance is more uniform; and the arc LED street lamp utilizes a double-heat-radiation aluminum lamp body with the heat radiating fins and the transverse ventilation hole and utilizes a high-heat-conduction ceramic base plate as an LED radiating carrier to reduce heat accumulation of the LED so as to further effectively reduce the light attenuation of the LED and prolong the service life of the LED street lamp.
Description
Technical field
The utility model relates to the LED lighting engineering, particularly a kind of cambered surface high-efficiency heat radiating LED street lamp.
Background technology
The LED street lamp has advantages such as long service life, economize on electricity; It all is to be fixed on the plane that but existing LED street lamp carries the aluminium base of LED lamp pearl; This just causes the rising angle of LED consistent, makes illuminating area receive certain restriction, cause lamp under brighter; And have the phenomenon of dark space on every side, make road illumination inhomogeneous.Existing LED road lamp cooling mode generally adopts the aluminium section bar that has radiating fin; Main lean on the radiation mode heat radiation, for the bigger LED street lamp of the above power of 100W, because caloric value is big; It is unsatisfactory to depend merely on the heat loss through radiation effect; The heat that can not rapidly LED be sent is dispersed in the air, and the accumulation of these heats will cause the light decay in advance of LED, influences the normal service life of LED street lamp.
Summary of the invention
The purpose of the utility model is to provide a kind of cambered surface high-efficiency heat radiating LED street lamp; It can solve existing LED street lamp technology and exist rising angle little; The uneven problem of road illumination, and it is bad and be directed at the problem that light decay appears in LED in advance to have solved high-power LED street lamp heat radiation.
The utility model is realized through following technical scheme: cambered surface high-efficiency heat radiating LED street lamp; Comprise aluminum lamp body and Transparent lamp shade, be provided with fixed installation hole and radiating fin above the lamp body, installing hole is fixing constant-current driving power supply at the back; Be provided with the transverse convection hole of heat transmission in the middle of the lamp body; Fixing ceramic substrate below the lamp body welds led array on the ceramic substrate, the foot of lamp body is installed Transparent lamp shade.Below the said lamp body fixedly the face of ceramic substrate be arc, ceramic substrate is a long strip type, has 7; Be fixed to uniformly on the cambered surface below the lamp body; This makes that the light-emitting area of LED street lamp no longer is a plane, and rising angle becomes 220 degree by 180 traditional degree, and illuminating area obviously increases.The substrate of fixed L ED adopts ceramic substrate, and ceramic substrate is also named alumina ceramic-base copper-clad plate (DCB), is 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 property and high-termal conductivity; Current capacity is big, and mechanical strength is high, and its thermal conductivity factor reaches 24W/ (m.K); More than 10 times, heat-conducting effect significantly improves than aluminium base plate hight.
For further realizing the purpose of the utility model; Also adopted following technical scheme: on radiating mode except utilizing the heat loss through radiation of radiating fin; Also in the middle of lamp body, set up the transverse convection hole; Through the transverse convection of air, quicken to take away the heat that LED sends from the aluminum lamp body, further strengthened radiating effect.
The good effect of the utility model is: it as light emitting source, adopts the exiting surface of arc with LED, makes the illuminating area of LED street lamp bigger; Road illumination is more even; And adopt the dual heat radiation aluminum lamp body have radiating fin and transverse convection hole, as the LED carrier that dispels the heat, reduce the thermal accumlation of LED with the high heat-conducting ceramic substrate; Thereby reduce the light decay of LED effectively, the LED street lamp is really accomplished the long-life.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
As shown in the figure; The said cambered surface high-efficiency heat radiating LED of the utility model street lamp comprises aluminum lamp body 1 and Transparent lamp shade 7, is provided with fixed installation hole 2 and radiating fin 3 above the lamp body 1; Installing hole 2 back are constant-current driving power supply 8 fixedly; Be provided with the transverse convection hole 4 of heat transmission in the middle of the lamp body 1, lamp body 1 following fixedly ceramic substrate 5, welding led array 6 on the ceramic substrate 5.Said lamp body 1 adopts aluminum alloy extrusion section bar to make, and the lamp body 1 following fixedly face of ceramic substrate is an arc.Led array 6 usefulness reflow soldering processes are soldered on the ceramic substrate 5, and ceramic substrate 5 is fixed on the cambered surface below the lamp body 1, and ceramic substrate 5 is connected with lamp body 1 top constant-current driving power supply 8 through lead, and Transparent lamp shade 7 is installed at last.When the utility model uses, by above-mentioned requirements each parts of processing and assembling.
The utility model not technology contents of detailed description is known technology.
