Abstract
The invention discloses an LED road lamp capable of dissipating heat by coolant liquid in a sleeve of a lamp pole pipe, an inner chamber is sleeved in an external chamber, an inner wall of the external chamber and an external wall of the inner chamber form a cavity connected with a cavity lamp holder, the coolant liquid having heat capacity is contained in the cavity, a thermal conduction device is placed in the coolant liquid to dissipate the heat of the LED in the coolant liquid, the heat of the coolant liquid is dissipated out by an external surface of the external chamber, and a heat dissipating air current in the inner chamber flows to dissipate the heat. The LED road lamp capable of dissipating heat by coolant liquid in the sleeve of the lamp pole pipe has the following benefits: the coolant liquid contained by the lamp pole has good heat dissipating and conducting capability and high heat capacity, the heat is dissipated in multiple ways, such as that the surface of the lamp pole dissipates the heat and the air current in the cavity flows to dissipate the heat, so that good heat dissipation effect is implemented.
Description
Technical field
The present invention relates to the LED street lamp, especially the LED street lamp of light pole pipe-in-pipe dress cooling fluid heat radiation.
Background technology
Mostly there is the drawback that area of dissipation is little, radiating rate is unhappy in existing LED street lamp, as Chinese patent Granted publication number: the LED street lamp that CN201496845U tells about is that lamp holder water-cooled and lamp holder radiating fin dispel the heat, be subjected to the restriction of volume, weight, cost etc. because of LED lamp holder radiator, that can not do is very big, cause that area of dissipation is little, radiating rate is unhappy, the adverse consequences that is produced is that the LED radiating effect is undesirable, light decay is serious.
Summary of the invention
In order to overcome the existing unfavorable problem of LED road lamp cooling effect, the invention provides a kind of with dress cooling fluid in the lamp stand pipe-in-pipe of LED street lamp dispel the heat, the heat radiation of lamp stand tube-surface, the method that the multipath of interior tube chamber air-flow heat radiation dispels the heat.
It is as follows that the present invention solves the technical method that its technical problem adopts:
With suit inner chamber body in the outer chamber, the inwall of outer chamber and the outer wall of inner chamber body form cavity, this cavity is connected with the cavity lamp holder, be equipped with in the cavity and hold the big cooling fluid of heat, heat-transfer device is placed in the cooling fluid, heat-transfer device is led the heat of LED and is dispersed in the cooling fluid, and the heat of cooling fluid is left by the outer surface of outer chamber, and the radiating airflow in the inner chamber body flows and dispels the heat.
The invention has the beneficial effects as follows: with lamp stand pipe-in-pipe dress cooling fluid heat conduction and heat radiation, hold that heat is big, the multipath heat radiation of lamp stand surface radiating, the heat radiation of cavity air current flow, reach the good heat dissipation effect purpose.
