As an improvement of the above technical solution, the heat sink includes a mainboard and two scoreboards being symmetrical set, The scoreboard is connected as one with mainboard, and the junction of the lampshade and mounting plate is fully welded with mainboard to be connect.
As an improvement of the above technical solution, the scoreboard and mainboard are made of aluminium alloy, the end plating of the scoreboard There is copper plate.
As an improvement of the above technical solution, the cross-sectional area of the copper plate is greater than or equal to square millimeter.
As an improvement of the above technical solution, the lampshade is internally provided with fan, and the inside of the lampshade is additionally provided with For controlling the temperature detect switch (TDS) of fan, circuit is connected with circuit where temperature detect switch (TDS) where the fan.
As an improvement of the above technical solution, the plate face of the mounting plate is provided with multiple heat release holes.
The radiating efficiency of superelevation radiating efficiency LED lamp of the present invention is high, even if its rated power is 100W, at 25 DEG C In the environment of work, maximum temperature be no more than 36 DEG C.It, can when causing lampshade internal temperature excessively high because ambient temperature is excessively high By fan come forced heat radiation, the fan is controlled by temperature detect switch (TDS), energy conservation and environmental protection.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of superelevation radiating efficiency LED lamp of the present invention;
Fig. 2 is the structural schematic diagram of heat sink of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
As shown in Figure 1, 2, the superelevation radiating efficiency LED lamp, including mounting plate 10, lampshade 11, setting are in lampshade 11 The heat sink that multiple cross sections are Y shape is installed with outside internal LED lamp bead, the lampshade 11 and the junction of mounting plate 10 12.The heat sink 12 includes that a mainboard 21 and two scoreboards 22 being symmetrical set, the scoreboard 22 are connect with mainboard 21 It is integrated, the junction of the lampshade 11 and mounting plate 10 is fully welded with mainboard 21 to be connect.The scoreboard 22 and mainboard 21 are by aluminium Alloy is made, and the end of the scoreboard 22 is coated with copper plate 221.
According to tip fuel factor it is found that the cross section of the heat sink 12 is Y shape, this facilitates lampshade 11 and mounting plate 10 Junction heat to the end of scoreboard 22 concentrate, there are two " tips " for the heat sink 12, and heat dissipation area is corresponding Increase, therefore radiating efficiency can be further increased.Although the thermal conductivity of fine copper is much larger than aluminium, for copper, aluminium Cost is relatively low for alloy.Be made to obtain control LED lamp of aluminium alloy entirely if the heat sink 12 is entire, 25 DEG C according to Rated power works 5 hours, and the internal temperature of 10 junction of the lampshade 11 and mounting plate is 36.3~36.8 DEG C.And it is of the invention The superelevation radiating efficiency LED lamp works 5 hours at 25 DEG C according to rated power, and the lampshade 11 and mounting plate 10 connect The internal temperature for meeting place is 33.6~33.9 DEG C;That is, by the way of copper plate 221 is arranged, it can reduce 2.7~ 2.9℃;Radiating efficiency further increases.Wherein, the cross-sectional area of the copper plate 221 cannot be too small, the copper plate 221 Cross-sectional area is greater than or equal to 8 square millimeters.
Although the superelevation radiating efficiency LED lamp is very high from radiating efficiency, even if rated power is 100W, 25 It works in the environment of DEG C, maximum temperature is no more than 36 DEG C.But if make for a long time in the very high area of some environment temperatures With to avoid the temperature excess temperature inside lampshade 11, the lampshade 11 is internally provided with fan, and the inside of the lampshade 11 is also set up There is the temperature detect switch (TDS) for controlling fan, circuit is connected with circuit where temperature detect switch (TDS) where the fan.Inside lampshade 11 Temperature reach setting value, if temperature reaches 36 DEG C, the temperature detect switch (TDS) is connected, and the fan is powered on, fan energization work Make that forced heat radiation can be carried out to the inside of lampshade 11;Temperature inside lampshade 11 be reduced to 36 DEG C hereinafter, the fan not Work, energy conservation and environmental protection.
Further, to improve radiating efficiency, the plate face of the mounting plate 10 is provided with multiple heat release holes 101.
In the above-described embodiments, even if the superelevation radiating efficiency LED lamp rated power is 100W, in 25 DEG C of environment Lower work, maximum temperature are no more than 36 DEG C.When causing 11 internal temperature of lampshade excessively high because ambient temperature is excessively high, can pass through Fan carrys out forced heat radiation, and the fan is controlled by temperature detect switch (TDS), energy conservation and environmental protection.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
