Abstract
The invention relates to an LED street lamp cooling system which reduces the LED working temperature by self cross-ventilation. When the temperature is higher, forced ventilation measures are started by a fan.
Description
Technical field
The present invention relates to a kind of mode that LED illumination, LED display and other high-altitudes need solve heat radiation, be particluarly suitable for using on the LED street lamp.Native system mainly distributes the heat that LED work is produced by cross-ventilation.When temperature is too high by the fan work forced heat radiation.Advantages such as that native system has is energy-conservation, simple in structure, easy for installation, highly versatile transform on conventional lamp and just can use, and the life-span are long.
Technical background
At present, known LED illuminating and heat radiating generally all is by the area of dissipation that increases aluminum or copper radiator or takes liquid coolant to lower the temperature, and cost height, loss height, weight big, inconvenience is installed, versatility is poor.
Summary of the invention
For overcome LED illuminating and heat radiating cost height, weight is big, the invention provides a kind of is main heat radiation by the natural wind convection current, fans drive is the device of auxiliary heat dissipation, and is simple in structure, easy for installation, cost is low, the life-span is long.
The technical solution adopted for the present invention to solve the technical problems
The all aluminium radiator of LED illuminating and heat radiating adopts the ventilated type radiator, radiator tandem in the air channel of free convection.A fan is installed on top, starts the forced ventilation cooling when temperature surpasses the temperature that temperature switch controls.Air inlet is in the lamp stand bottom, and lamp stand forms cross-ventilation as the height of air channel rod and the temperature of radiator.Air outlet can dustproof and rainproof below lamp.
Beneficial effect of the present invention is to play thermolysis by radiator again by natural convection air, and is simple in structure, volume is little, in light weight, easy for installation, highly versatile, low, the long service life of cost.

The specific embodiment
Cold wind stream (1) enters radiator (10) by fresh air inlet (17) through lamp stand (16), the bar of raising the wick of an oil lamp (6), ventilation duct (3) in Fig. 1,2, discharge by air outlet (4) by fan (9), hot blast stream (7), form a complete radiating airflow, the heat that LED produced is taken away.When radiator (10) temperature surpassed the temperature that temperature detect switch (TDS) (13) controlled, fan (9) starts forced air draft.
Claims (4)
1. LED street lamp cooling system, by the end air inlet of lamp stand top through lamp stand, the bar of raising the wick of an oil lamp, ventilation duct, radiator, to the cooling system of air outlet discharge.
2. radiator temperature is to when should not be in rising, the starting fan cooling.
3. require described LED street lamp cooling system feature to be according to right 1: the temperature that reduces radiator with the cross-ventilation of lamp stand bottom inflow generation.
4. require described LED street lamp cooling system feature to be according to right 2: fan work when temperature is high, play energy-conservation, reduce loss, increase the service life.
