Description
Technical field
The utility model relates to the illuminating street lamp field, specifically a kind of inclined type heat pipe heat radiation large LED street lamp.
Background technology
The LED street lamp becomes the first-selected product of energy-conserving road lamp with advantages such as its exclusive long-life, energy-conserving and environment-protective, high brightness, is the novel lamp source that the public illumination field is used for replacing conventional road lamp (mercury lamp, sodium vapor lamp).Therefore, countries in the world are all with the Application and Development of the LED street lamp key project as national energy-conserving and environment-protective, and list in the national budget.
A maximum application obstacle of the current existence of LED street lamp is exactly the too high problem of junction temperature, and this problem has been listed in important brainstorm subject in the world.At present, the junction temperature of high-power LED street lamp still is stuck in about 70 ℃, and the best junction temperature of LED lamp is below 60 °, and the too high meeting of junction temperature causes a series of problems such as light decay phenomenon, life-span reduction, makes the application of LED street lamp be subjected to difficult restriction of having gone beyond.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides the tilting UNICOM of a kind of heat pipe split type LED heat radiating device of road lamp, realize the constant effect of control LED junction temperature, improve the service life of LED street lamp, can also be implemented in eaily under the situation of not changing former street lamp electric pole and circuit, to the raising and the transformation of original street lighting state.
The technical scheme in the invention for solving the technical problem is: this kind inclined type heat pipe heat radiation large LED street lamp, comprise that lamp stand, described lamp stand comprise cross bar and upper support bar, the LED lamp holder is arranged on the cross bar, be provided with the lamp pearl in the LED lamp holder, described lamp pearl links to each other with heat-pipe radiator, it is characterized in that, described heat-pipe radiator one end connects the lamp pearl in the LED lamp holder, the other end is connected on the upper support bar, with respect to the horizontal plane is tilting state.
In needing under the situation of consideration actual installation and heat-pipe radiator heat radiation, the axis of described heat-pipe radiator straightway and the setting angle between the horizontal line are 5 °～45 °.
For ease of installing, particularly the actual needs that existing street lamp is transformed links together by the transition piece heating column between described heat-pipe radiator and the LED lamp pearl.
Be provided with the adopting heat pipes for heat transfer element in the described radiator.
For ease of installing, the junction of described heat-pipe radiator and upper support bar is provided with No. two adaptors of T type.
For the raising and the transformation of original street lighting state, need to add upper support bar, therefore, upper support bar and lamp stand split connect by No. three adaptors of yi word pattern between the two.
As required, described LED street lamp is provided with in the lamp stand bilateral symmetry.
The beneficial effects of the utility model are: this inclined type heat pipe heat radiation large LED street lamp can be with the test by method of controllable junction temperature of LED in 60 ℃, street lamp is operated in the best working range, make improve 20% the service life of LED, substantially stop the light decay phenomenon of LED, make LED bring into play its light efficiency to greatest extent.Simultaneously simple in structure, profile is succinctly attractive in appearance, both has been suitable for brand-new street lamp design, can satisfy again existing street lamp transformation.
