Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "mounted on" another element, it can be directly mounted on the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, the present invention provides a lighting lamp, which includes a power socket 1, a circuit board 3, a light-emitting lamp panel 4 and a metal heat dissipation cover 2.

At first, the heat conductivity of metal is far stronger than the heat conductivity of air, and consequently, when luminous lamp plate 4 and circuit board 3 were located to metal heat dissipation cover 2 cover, metal heat dissipation cover 2 can absorb the heat that luminous lamp plate 4 and circuit board 3 produced fast and go in giving off the outside air with the heat that absorbs fast. Therefore, the metal heat dissipation cover 2 greatly accelerates the heat dissipation speed of the illuminating lamp.

And, from the formula Q ═ c × m Δ t (Q is the heat absorption capacity of the body, c is the specific heat capacity of the body, m is the mass of the body, Δ t is the temperature change of the body), Δ t ═ Q/(c × m). As can be seen from the above equation, in the case where the heat amount Q absorbed by the object is the same, the temperature change Δ t of the object is inversely proportional to the mass m of the object, and the temperature change Δ t of the object is inversely proportional to the specific heat capacity c of the object. The specific heat capacity of the common metal is between 0.4 KJ/Kg/DEG C and 0.9 KJ/Kg/DEG C, and the density of the common metal is more than 2.7 multiplied by 103Kg/m³. The specific heat capacity of air is 1 KJ/Kg/DEG C, and the density of air is 1.293Kg/m³. The mass is equal to the product of the density and the volume, so that the mass of the metal is more than 1000 times that of the air for the same volume of metal and air. While the specific heat capacity of air generally does not exceed that of metalThree times the specific heat capacity. Therefore, as can be seen from the above, when the absorbed heat amounts Q are the same and the volumes are the same, the temperature change of the metal is much smaller than the temperature change of the air. Consequently, metal heat exchanger 2 can greatly reduce the average temperature of circuit board 3 and luminous lamp plate 4 surrounding air for the temperature of circuit board 3 and luminous lamp plate 4 surrounding air can not rise too high, thereby is favorable to protecting circuit board 3 and luminous lamp plate 4.
