It should be noted that, because the coefficient of heat conduction of described first heat dissipating layer of the heat-dissipating cylinder of above-mentioned lighting apparatus, described second heat dissipating layer and described 3rd heat dissipating layer successively decreases successively, define the decreasing gradient of the coefficient of heat conduction, relative to the simple metal such as fine copper or fine aluminium, guaranteeing that under the prerequisite that heat dispersion is higher, quality also greatly reduces.
Such as, the lighting apparatus that the mutual combination that other embodiments of lighting apparatus of the present invention also comprise the respective embodiments described above is formed.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the each piece of all possible combination of technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
