DESCRIPTION OF EMBODIMENTS

(5) The attached drawings are for illustration only and are not intended to limit the present invention. Some components in the attached drawings are omitted, enlarged or reduced for better illustrating the embodiments, and sizes of these components do not represent sizes of actual product. For those skilled in the art, it will be understood that some known structures in the drawings and descriptions thereof are omitted. The positional relationships described in the drawings are for illustration only and are not intended to limit the present invention.

(6) As shown in FIGS. 1 to 4, a waterproof stage light with efficient heat dissipation according to one preferable embodiment includes a light source component, a heat dissipating system and a main housing 1 which is waterproof, wherein an opening 101 is arranged at the rear end of the main housing 1, the heat dissipating system is in seal connection with the opening 101 such that the main housing 1 forms an enclosed space; one end of the heat dissipating system is positioned inside the main housing 1 and the other end thereof is positioned outside the main housing 1; and the light source component is positioned on the end of the heat dissipating system that is positioned inside the main housing 1. Such an arrangement causes that the heat generated by the light source component can be directly absorbed by the end of the heat dissipating system that is positioned inside the main housing 1, the heat dissipating system directly then transfers the absorbed heat to the other end through heat exchange and then discharges the exchanged heat to the outside of the light. Therefore, the heat generated by the light source during operation can be well discharged in time.

(7) As shown in FIGS. 1 to 4, the heat dissipating system contains a heat absorbing component, a heat transfer substrate 4, and a heat dissipating component. The heat transfer substrate 4 covers the opening 101 at the rear end of the main housing 1 and is in seal connection with the main housing 1. The heat absorbing component and the heat dissipating component are respectively arranged on both sides of the heat transfer substrate 4. In addition, the heat absorbing component is located inside the main housing 1, and the heat dissipating component is located outside the main housing 1. Through such configuration, the heat absorbing component can absorb the heat generated by the light source component, then the absorbed heat can be exchanged to the heat dissipating component by the heat transfer substrate 4, and the heat dissipating component will dissipate the exchanged heat to the outside of the light.

(8) As shown in FIGS. 1 to 3, a first waterproof seal ring 5 is arranged between the heat transfer substrate 4 and the main housing 1. A first annular groove 6 surrounding the opening 101 is arranged on the rear end surface of the main housing 1. The heat transfer substrate 4 is fixed with the main housing 1 via a bolt. One side of the first waterproof seal ring 5 is embedded in the first annular groove 6, and the other side is in close contact with the heat transfer substrate 4. The arrangement of the first waterproof seal ring 5 can prevent rainwater or the like from entering the inside of the main housing 1 through the junction of the heat transfer substrate 4 and the main housing 1.

(9) As shown in FIGS. 1, 2 and 4, the heat absorbing component is provided with an installation position 9. The light source component, containing a light source 2 and a reflecting device 3 surrounding the light source 2, is installed in the installation position 9. In addition, the heat absorbing component surrounds the reflecting device 3 of the light source component and is attached to the reflecting device 3 of the light source component.

(10) As shown in FIGS. 1 and 4, the heat absorbing component contains a plurality of heat absorbing fins 7 and a plurality of first heat transfer tubes 8. The heat absorbing fins 7 are arranged in parallel, and a gap is formed between adjacent heat absorbing fins 7 to form an air channel for air circulation. One end of each of the first heat transfer tubes 8 is arranged to pass through the heat absorbing fins 7, and the other end is connected with the heat transfer substrate 4.

(11) As shown in FIGS. 1 and 4, the heat dissipating component contains a plurality of heat dissipating fins 10 and a plurality of second heat transfer tubes 11 and a heat dissipating fan 12, wherein the heat dissipating fins 10 are arranged in parallel, and a gap is formed between adjacent heat dissipating fins 10 to form an air channel for air circulation. The heat dissipating fan 12 is arranged at a tuyere position of the air channel. The extending directions of the air channel of the heat dissipating component are staggered with that of the air channel of the heat absorbing component to better dissipate heat generated by the light source component. In order to achieve waterproof performance of the light, the heat dissipating fan 12 is configured to be a waterproof fan. One end of each of the second heat transfer tubes 11 is arranged to pass through the heat dissipating fins 10, and the other end is connected with the heat transfer substrate 4. Since the heat dissipating component is positioned outside the main housing 1 and has a corresponding air channel for air circulation, the heat transferred from the light source component inside the main housing 1 can directly exchange heat with the external space, which can achieve desired heat dissipation effect. In addition, the heat dissipating component is non-conductive, and the heat dissipating fan 12 is waterproof, the entire heat dissipating component thus can be exposed to rain or water, which does not influence the using effect of the light.

(12) As shown in FIGS. 1 and 2, the outer periphery of the heat dissipating component is provided with a protective housing 13 containing a heat dissipating port 14, and the heat dissipating port 14 corresponds to the position of the heat dissipating fan 12. The arrangement of the protective housing 13 can well protect the heat dissipating component, and the arrangement of the heat dissipating port 14 will not hamper heat dissipation of the heat dissipating component.

(13) As shown in FIGS. 1 and 3, the outer side of the main housing 1 is provided with a plurality of sheet protrusions 15, distributed along the circumferential direction of the main housing 1, for effectively diffusing the heat to external air, which is conducted from the inside of the light to the main housing 1, thus accelerating the dissipating flow of the thermal airflow to achieve efficient heat dissipation. A maintenance port 16 containing a maintenance cover 17 is arranged on the rear side or a front side of the main housing 1. The maintenance port 16 is configured to facilitate maintenance and cleaning of the light. The maintenance cover 17 is fixedly connected with the main housing 1 through a bolt, and a second waterproof seal ring 18 is arranged between the maintenance cover 17 and the main housing 1. A second annular groove 19 surrounding the maintenance port 16 is arranged on the main housing 1. One side of the second waterproof seal ring 18 is embedded in the second annular groove 19, and the other side is in close contact with the maintenance cover 17. The second waterproof seal ring 18 is arranged so that rain water or the like can be prevented from entering the inside of the main housing 1 from the junction of the maintenance cover 17 and the main housing 1.

(14) As shown in FIGS. 1 and 2, the front end of the main housing 1 is provided with a light exit 20, and the light exit 20 contains a light-exiting lens 21. A third waterproof seal ring 22 is arranged between the light-exiting lens 21 and the main housing 1. The main housing 1 is connected with a U-shaped support frame, and a fourth waterproof seal ring is arranged at the junction between the main housing 1 and the U-shaped support frame. The arrangement of the third waterproof seal ring 22 and the fourth waterproof seal ring can prevent rainwater or the like from entering the inside of the main housing 1 from the corresponding junction.
