Abstract
The invention discloses a light-emitting diode (LED) road lamp with a built-in water-cooled radiator. The LED road lamp with the built-in water-cooled radiator comprises a cooling water tank, an LED chip, a heat conduction seat, a water pump, the radiator, a radiator fan and water pipes. The cooling water tank is connected with the water pump through the water pipe, the water pump is further connected with the heat conduction seat through one water pipe, the heat conduction seat is a metal block in which a water channel is reserved, the LED chip is arranged on the upper portion of the heat conduction seat, the heat conduction seat is connected with the radiator through one water pipe, radiating fins are arranged on the radiator, the radiator is further connected with the cooling water tank through one water pipe, and the radiator fan is arranged on one side of the radiator. Cooling water is adopted as the medium for transferring heat, the built-in water-cooled radiator type LED road lamp has the heat dissipation effect which is much better than the effect of air cooling and natural cooling, is particularly suitable for being used in high-power LED chips, the heat dissipation effect is good, and the service life is long.
Description
Technical field
The present invention relates to a kind of LED lamp, relate in particular to a kind of built-in water-cooling heat radiator type LED street lamp.
Background technology
At present, the LED illuminating product is replacing traditional lighting gradually becomes the main flow illuminating product.For the high-power LED street lamp, the height of light efficiency is key factor, however the heat radiation of LED lamp be realize long-life and high light efficiency to the pass factor.A lot of reports about street lamp initial failure are arranged in reality, be referred to as dead lamp, this is a restriction greatly to public illumination.Therefore, the heat radiation that how to improve heavy-power LED product is the important topic that increases the service life.As everyone knows, the LED photoelectric transformation efficiency is between 15-20%, and remaining electric energy is whole energy transform into heat energies almost, therefore, when the LED lamp lighting, can produce a large amount of heats.If this heat is not distributed as soon as possible, thing followed fuel factor will be very obvious.This will cause the chip internal heat accumulation, causes the emission wavelength drift, and luminous efficiency descends, and shorten service life.
At present, the heat radiation of LED street lamp is mainly by natural heat dissipation, namely utilizes on the louvre on lamp housing the air convective zone to walk heat, and radiating effect is undesirable, affects the service life of LED street lamp.
Summary of the invention
The purpose of this invention is to provide a kind of LED street lamp that utilizes water-cooling, it has good heat dissipation effect, energy-conserving and environment-protective, life-extending function.
the objective of the invention is to be achieved through the following technical solutions, this built-in water-cooling heat radiator type LED street lamp comprises cooling water tank, LED chip, heat-conducting seat, water pump, radiator, radiator fan, water pipe, described cooling water tank is connected with water pump by water pipe, water pump is connected with heat-conducting seat by water pipe again, described heat-conducting seat is the metal derby that water channel is left in an inside, heat-conducting seat top is provided with LED chip, described heat-conducting seat is connected with radiator by water pipe, described radiator is provided with fin, described radiator is connected with cooling water tank by water pipe again, described radiator one side is provided with radiator fan.
Described heat-conducting seat is copper material.
Cooling water in cooling water tank is taken away by water pump and is sent to heat-conducting seat, enter again radiator after taking away the heat that LED chip distributes on heat-conducting seat, by after the radiator fan cooling, the cooling water after cooling is got back to cooling water tank by water pipe again, carries out next circulation in radiator.
Beneficial effect of the present invention: adopt the conduction heat take cooling water as medium, air-cooled and naturally cooling incomparable radiating effect is arranged, be particularly suitable for using good heat dissipation effect, long service life on high-power LED chip.

Fig. 1 is schematic diagram of the present invention
In figure: 1, cooling water tank 2, LED chip 3, heat-conducting seat 4, water pump 5, radiator 6, radiator fan 7, water pipe
The specific embodiment
As shown in Figure 1, this built-in water-cooling heat radiator type LED street lamp comprises cooling water tank 1, LED chip 2, heat-conducting seat 3, water pump 4, radiator 5, radiator fan 6, water pipe 7, cooling water tank 1 is connected with water pump 4 by water pipe 7, water pump 4 is connected with heat-conducting seat 3 by water pipe 7 again, heat-conducting seat 3 is metal derbies that water channel is left in an inside, heat-conducting seat 3 tops are provided with LED chip 2, heat-conducting seat 3 is connected with radiator 5 by water pipe, radiator 5 is provided with fin, radiator 5 is connected with cooling water tank 1 by water pipe again, and radiator 5 one sides are provided with radiator fan 6.
Cooling water in cooling water tank 1 is taken away by water pump 4 and is sent to heat-conducting seat 3, enter again radiator 5 after taking away the heat that LED chip 2 distributes on heat-conducting seat 3, by after radiator fan 6 coolings, the cooling water after cooling is got back to cooling water tank 1 by water pipe again, carries out next circulation in radiator 5.
