Description

A kind of high-power integrated LED street lamp
Technical field
The utility model belongs to the houselights technical field, relates to a kind of LED lamp, is specifically related to a kind of high-power integrated LED street lamp.
Background technology
At present, street lamp has become city indispensable lighting installation at night, and street lamp needs work for a long time, owing to exist the different variations in various weather and season, some atrocious weather environment often causes the life-span of general street lamp not long.Especially also there is the high shortcoming of power consumption in traditional street lamp, so the LED luminous tube is applied to street lighting, can solve the high shortcoming of power consumption.But LED luminous tube, particularly great power LED luminous tube, owing to work under various environment for a long time, its heat dissipation problem becomes the matter of utmost importance that influences its life-span.For solving the heat dissipation problem of high-power LED street lamp, many people have carried out many improvement to the application of high-power LED street lamp, and installed fin additional at high-power LED street lamp, but the heat-transfer rate of the fin that installs additional itself is slow, can not in time heat be derived and distribute, improved effect is still not obvious, does not reach the requirement of anticipation.
Summary of the invention
The purpose of this utility model provides a kind of high-power integrated LED street lamp; employing will be installed aluminium circuit board and the temperature-uniforming plate and the close-connected mode of copper heat pipe of high-powered LED lamp; by the inside of copper heat pipe the heat-conducting liquid heat absorption is housed; the fin that is provided with through the lampshade shell surface is again realized fast cooling; overcome existing high-power LED street lamp heat conduction, the slow shortcoming of heat radiation, played the effect that the protection high-powered LED lamp prolongs its service life.
The technical scheme that the utility model adopted is, a kind of high-power integrated LED street lamp, comprise street lamp connector, street lamp case, heat sink, be installed in some high-power LED chips and driving power on the aluminium circuit board, described aluminium back of circuit board connects a temperature-uniforming plate, temperature-uniforming plate is anchored on the copper heat pipe in the type groove that the inboard heat sink of street lamp case is provided with through cover plate, described some high-power LED chip adopts parallel connection or series system to connect, and is fixed in half hole that the aluminium circuit board is provided with.
High-power integrated LED street lamp described in the utility model, its feature also be,
Heat-conducting liquid has all been filled in the inside of described temperature-uniforming plate and copper heat pipe.
The described street lamp case outside is provided with radiating fin.
The cover plate back side of described installation temperature-uniforming plate is provided with the type groove that matches with the copper heat pipe.
The high-power integrated LED street lamp of the utility model, employing will be installed aluminium circuit board and the temperature-uniforming plate and the close-connected mode of copper heat pipe of high-powered LED lamp, connect a temperature-uniforming plate at the aluminium back of circuit board that some led chips are installed, and temperature-uniforming plate and copper heat pipe are anchored in the type groove that the inboard heat sink of lampshade shell is provided with by cover plate.Because heat-conducting liquid is all filled in the inside of temperature-uniforming plate and copper heat pipe; the heat that produces in the time of can absorbing the led chip energising effectively; be provided with radiating fin through the street lamp case outside again and realize the fast cooling heat radiation, the effect of having played the protection high-powered LED lamp and having prolonged its service life.
Description of drawings
Fig. 1 is the high-power integrated LED lamp post structure of a utility model schematic diagram;
