LED (Light Emitting Diode) is light emitting diode, is a kind of solid-state semiconductor devices, and it can be directly luminous energy electric energy conversion.LED light fixture is to utilize solid semiconductor chip as luminescent material, in semiconductor, by carrier, occurs compoundly to emit superfluous energy and cause photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light.Under the background that Present Global energy starved worry raises once again, saving the energy is the important problem that we shall face future, and at lighting field, LED light fixture, as a kind of novel green light source product, must be the trend of future development.
But because the caloric value of LED light source is large, need heat radiation to guarantee that it normally works, existing LED light fixture is when carrying out heat dissipation design, all generally that fin is set, by fin, dispel the heat, but the radiating efficiency of fin is poor in the market, has greatly affected the service life of LED light fixture.
But because the caloric value of LED light source is large, need heat radiation to guarantee that it normally works, existing LED light fixture, when carrying out heat dissipation design, is all generally that fin is set, and by fin, dispels the heat.Because application scenario is different, the profile of LED lamp has very large difference, thereby radiator structure is also different.
The utility model is for picture street lamp or the isostructural LED lamp of desk lamp, in prior art, this LED lamp comprises horizontal lamp body, be fixed on the lamp holder of lamp body sidepiece, described lamp body comprises substrate, and LED chip array and lampshade are equipped with in described substrate one side, and heat sink is equipped with in another side, the side that described heat sink is relative with substrate is provided with some row's thermal columns, and the heat sink between two row's thermal columns is provided with one or more louvres.
By louvre is set, can make the hot gas in lampshade discharge fast, but the water of external environment or other magazines easily enter lampshade by louvre, affect the normal work of LED chip and power circuit.
Utility model content
The utility model provides in a kind of and has established the LED lamp of heat dissipation channel, then guarantees sealing when improving radiating effect, extends the service life of LED lamp, guarantees that LED chip and circuit normally work.
In a kind of, establish the LED lamp of heat dissipation channel, comprise substrate, LED chip array and lampshade are equipped with in substrate one side, heat sink is equipped with in another side, described heat sink is provided with at least one first louvre, the surface of described lampshade caves inward and forms the heat dissipation channel that extends to substrate, and described substrate is provided with the second louvre that is communicated with the first louvre and heat dissipation channel.
In said structure, described heat dissipation channel is communicated with the first louvre, because the heat of lampshade part is higher, therefore in heat dissipation channel, air themperature is higher, due to the principle of hot gas rising, hot gas in heat dissipation channel flows out from the first louvre by the second louvre, the cold air of lamp body below is sucked in heat dissipation channel simultaneously, the formation cooling blast that moves in circles, the heat in lamp body is shed fast, greatly improve the radiating effect of LED lamp integral body, improve the service life of product.
In order further to improve the radiating effect of heat sink, preferred, the described heat sink dorsad side of substrate is provided with some row's thermal columns.Thermal column is set can effectively increase the area of dissipation of heat sink, thereby effectively improves radiating effect.
The setting of the first louvre is to be communicated with the second louvre and external environment, therefore, for the ease of manufacturing, preferred, and described the first louvre is the through hole between adjacent two row's thermal columns.Described through-hole structure is simple, easy to process.
For cooling blast can be circulated in heat sink, take away the more heat of lamp body, preferred, described first louvre one end is communicated with the second louvre, and the other end extends out to heat sink peripheral edge edge centered by the second louvre.Thereby described the first louvre circulates cooling blast from middle to circumferential extension in whole heat sink, further the heat dispersion of heat radiation plate.
For convenient first louvre of manufacturing, preferred, described the first louvre is towards open setting of a side of substrate, by substrate coordinate the first louvre that forms sealing.
For the heat of substrate can be delivered on thermal column fast, reduce the first louvre to the heat conducting impact of heat sink, further preferred, described the first louvre is between adjacent two row's thermal columns.
The beneficial effects of the utility model:
In of the present utility model, establish the LED lamp of heat dissipation channel, by the heat dissipation channel that is communicated to the first louvre is set on lampshade, thereby at the inner air-flow that forms circulation of lamp body, reduce the temperature of lamp body, extend the service life of product.
