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. 1-3, the present invention provides a lighting lamp, which comprises a power socket 1, a waterproof cover 2, a circuit board 3, a light-emitting lamp panel 4 and a metal heat dissipating tube 5. The waterproof cover 2 is connected with the power supply base 1, and the opening of the waterproof cover 2 faces to the direction far away from the power supply base 1. The circuit board 3 is arranged on one side of the waterproof cover 2 far away from the opening of the waterproof cover 2, and the circuit board 3 is electrically connected with the power supply base 1. Luminous lamp plate 4 is located and is close to 2 open-ended one sides of buckler in the buckler 2, and luminous lamp plate 4 electric connection circuit board 3. In the buckler 2 was located to metal heat dissipation section of thick bamboo 5, and the outside of luminous lamp plate 4 and circuit board 3 is located to metal heat dissipation section of thick bamboo 5 cover.

When the lighting lamp is in an operating state, firstly, the circuit board 3 processes the voltage provided by the power socket 1, generally, the circuit board 3 converts the high voltage (generally 125V or 220V) provided by the power supply into the low voltage (generally not more than 10V) available for the light-emitting lamp panel 4, and in the above process, the circuit board 3 generates a part of heat energy. Then, the light-emitting lamp panel 4 converts a part of the electric energy into light energy, and the other part of the electric energy is completely converted into heat energy to be diffused outwards. And circuit board 3 and luminous lamp plate 4 all locate in the buckler 2, consequently, the air in the buckler 2 can be heated to higher temperature.

Because still be equipped with a metal heat dissipation section of thick bamboo 5 in the buckler 2, and the outside of luminous lamp plate 4 and circuit board 3 is located to a metal heat dissipation section of thick bamboo 5 cover. The metal heat radiation cylinder 5 has a good thermal conductivity, and therefore, the metal heat radiation cylinder 5 absorbs heat in the air inside the waterproof cover 2. 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 is generally no more than three times that of metal. 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. Therefore, set up metal heat dissipation cylinder 5 in buckler 2, can greatly reduce the average temperature in buckler 2 for the temperature in buckler 2 can not rise too high, thereby is favorable to protection circuit board 3 and luminous lamp plate 4.
