Due to the copper containing 90 parts~95 parts of aluminium and 10 parts~15 parts in above-mentioned 3rd heat dissipating layer, the described 3rd can be made Heat dissipating layer still has the higher coefficient of heat conduction, can bear the lost work to the second heat dissipating layer after-heat. And above-mentioned 3rd heat dissipating layer may insure to scatter away these remaining heats by consistent, and then prevent heat described Accumulated on 3rd heat dissipating layer, cause hot-spot phenomenon.
It should be noted that due to first heat dissipating layer of the heat-dissipating cylinder of above-mentioned LED lamp, second heat dissipating layer and The coefficient of heat conduction of 3rd heat dissipating layer successively decreases successively, forms the decreasing gradient of the coefficient of heat conduction, relative to fine copper or pure The simple metal such as aluminium, on the premise of ensuring that heat dissipation performance is higher, quality is also greatly lowered.
For example, the other embodiment of the LED lamp of the present invention further include the respective embodiments described above be mutually combined institute's shape Into LED lamp.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality Apply all possible combination of each piece of technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously Therefore the limitation to the scope of the claims of the present invention cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
