Abstract
The utility model provides a water-cooled LED streetlamp, relating to the technical field of LED streetlamps, in particular to the cooling and the heat dissipation of the LED streetlamp. The water-cooled LED streetlamp comprises an LED and a metal base plate. The LED is arranged on the front surface of the metal base plate. A transparent cover for sealing the LED is arranged on the front surface of the metal base plate. The water-cooled LED streetlamp is characterized in that a heat dissipation water tank with a metal opening is arranged on the back surface of the metal base plate, a water inlet pipe is arranged on the heat dissipation water tank, and an electromagnetic valve which controls the water inlet pipe to supply water to the heat dissipation water tank is arranged on the water inlet pipe. After the LED is electrified to work, the electromagnetic valve is opened and heat on the metal base plate is absorbed by water to dissipate the heat of the LED. The heat dissipation water tank with the opening can accelerate the evaporation of water. Compared with the traditional LED streetlamp which only uses radiating fins to dissipate heat, the utility model has the advantages that the absorbed heat is more and the heat dissipation speed is fast. Moreover, the temperature of water under normal condition does not exceed 100 DEG C and the progress is remarkable when being compared with that of the traditional LED streetlamp.
Description
Technical field
The utility model relates to LED street lamp technical field, is specifically related to the cooling heat dissipation aspect of LED street lamp.
Background technology
As everyone knows, the LED street lamp is compared with conventional road lamp, and its advantage mainly shows: energy-conservation, light decay is little, the life-span is long and unleaded and mercury pollution, has the trend that progressively replaces the conventional high-tension sodium vapor lamp.The LED street lamp is compared with conventional road lamp, though be called as cold light source,, the LED street lamp still can produce certain heat when work, the LED normal working temperature should be less than 50 degrees centigrade, after 50 degrees centigrade, along with the rising light decay of temperature speeds up, the life-span shortens.At present, LED street lamp on the market is in order to solve overheated problem, it generally is the alloy fin that increases good heat conductivity at the substrate back of LED street lamp, because the surface area of fin is limited, radiating effect is unsatisfactory, the temperature of alloy fin will soon be raised during use, it is slow that heat on the alloy fin is delivered to airborne speed, the substrate temperature of LED street lamp is along with the increase temperature of working time constantly rises, even can reach 140 degree, what have a strong impact on the LED street lamp illuminates effect and life-span.
Summary of the invention
In sum, the purpose of this utility model is to solve the defective of existing LED road lamp cooling poor performance, and the water-cooled LED street lamp of a kind of usefulness that proposes.
For the technical scheme that solves the problem employing that the utility model proposed is: the water-cooled LED street lamp of a kind of usefulness, comprise: LED and metal substrate, described LED is located at the front of metal substrate, also be provided with translucent cover on the front of metal substrate with the LED sealing, be provided with the uncovered heat radiation pond of metal at the described metal substrate back side, the heat radiation pond is provided with water inlet pipe, and water inlet pipe is provided with the magnetic valve that the control water inlet pipe supplies water for the heat radiation pond.
Also include as the further improved technical scheme of the utility model:
Described magnetic valve is connected with single chip machine controlling circuit, the working power of the shared LED of single chip machine controlling circuit.
The pool wall in described heat radiation pond is provided with the water level inductive pick-up that is connected with single chip machine controlling circuit.
Fin in the described heat radiation pond.
The Chi Kou edge in described heat radiation pond is provided with metal fin.
Described metal fin is the shape that arc extends around Chi Kou.
The metal material that it is good that described metal fin is thermal conductivity is made.
The beneficial effects of the utility model are: after LED energising work, magnetic valve is an open mode, water inlet pipe is that the heat radiation pond of being located at the metal substrate back side adds an amount of water, the heat that absorbs on the metal substrate by water is the LED heat radiation, evaporation of water is quickened in uncovered heat radiation pond, the utility model and tradition only rely on the fin heat radiation to compare, and it is many to have a heat of absorption, the advantage that radiating rate is fast.In addition, water temperature is can not surpass 100 degrees centigrade under normal operation, compares with tradition to have obvious improvement.
