Description

Technical Field

[0002] A stage light is a commonly used stage lighting device, which is mainly used to provide performers with an excellent stage atmosphere and improve the viewing experience of the performance. The stage lights in the existing technology mainly include a lamp housing, a light source board, a lens body and a mounting bracket.

In order to improve the stage atmosphere effect, the light source board is a high-power multi-light source body, and is implemented in conjunction with multiple lens bodies. A large amount of heat is generated during use, which easily causes the temperature in the lamp housing to rise too quickly, generating a large amount of heat, and affecting the service life of the light source board. Moreover, due to the multi-lens body, it cannot be effectively limited in the existing technology, which affects the lighting effect and limits its practicality. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example

[0028] See Figures 1 to 3 As shown, a fan-heated stage lamp comprises a lamp housing 1, in which a light source board 2 is fixed, and a lampshade panel 4 with a plurality of irradiation circular holes 3 is provided, and a limiting support plate 6 with a plurality of circular through holes 5 is provided between the light source board and the lampshade panel; in this embodiment, the lamp housing is an aluminum structure or an insulating plastic structure, and at the same time, the irradiation circular hole is slightly smaller than the large diameter end of the lamp cup lens, so that the end of the lamp cup lens is stuck in the irradiation circular hole and will not fall off, and the diameter of the circular through hole is smaller than the large diameter end of the lamp cup lens, so that the middle part of the lamp cup lens can be limited when it is installed, preventing the lamp cup lens from shifting or shaking, thereby improving its installation stability and reliability.

[0029] In actual application, a plurality of limiting screw hole columns 7 are integrally formed on the inner wall of the lamp housing; the limiting screw hole columns are mainly used for limiting and ensuring the height of the heat dissipation gap, and are also conducive to fixing the light source board, the limiting support plate and the lampshade panel.

[0030] In this embodiment, a number of lamp cup lenses 8 are provided in the circular irradiation hole of the lampshade panel, the inner side of the lamp cup lens is inserted in the circular through hole, and the inner end face is attached to the irradiation surface of the light source board; and the screws pass through the lampshade panel, the limiting support plate and the light source board in sequence and are threadedly connected to the limiting screw hole column; that is, the three structures are positioned in a stacked manner on the lamp housing by screws, which ensures the installation stability of the overall structure, and is also conducive to reducing the use of screws and improving assembly efficiency.

[0031] After assembly, a heat dissipation gap is defined between the light source board and the top wall of the lamp housing. A fan 9 and a heat sink 10 are positioned within this gap, with the back of the light source board in close proximity to the fan and heat sink. Heat dissipation holes 11 are defined on the top wall of the lamp housing, with the fan and heat sink secured inside these holes. The heat sink conducts heat from the light source board and simultaneously dissipates it through the fan, thereby improving heat dissipation performance. Combined with the heat dissipation gap, this also prevents the temperature within the lamp housing from rising too quickly, thereby increasing the overall lifespan.

[0032] In actual use, the heat sink comprises a heat sink 101, several I-shaped heat conducting blocks 102 integrally formed on the side of the heat sink, and several thermal fins 103 integrally formed within the recessed areas of the I-shaped heat conducting blocks. During assembly, the end faces of the thermal fins and I-shaped heat conducting blocks are attached to the back of the light source board. The attachment of the I-shaped heat conducting blocks and thermal fins to the light source board facilitates heat conduction and dissipation, and the heat sink increases the heat dissipation area.

[0033] In actual use, the height of the heat sink is greater than that of the fan, and the height of the heat sink matches the height of the heat dissipation gap. When the fan is turned on, it can drive the airflow in the heat dissipation gap, blowing out the heat from the I-shaped heat-conducting block and the heat-conducting fins, thereby improving the heat conductivity of the heat sink. At the same time, external air can flow inward from the edge where the lampshade panel, the limit support plate 6, and the lamp housing are connected, and quickly blow the heat from the light source board outward through the through hole, thereby improving the heat dissipation effect.

[0034] In actual use, the limiting support plate is provided with a plurality of supporting protrusions 12, which are positioned against the surface of the light source board to limit the position. This ensures that the limiting support plate and the light source board are positioned stably and with a certain gap between them, allowing the light source board to have more space to release heat, thus preventing excessive temperature rise.

[0035] In actual application, the diameter of the circular through hole is smaller than the diameter of the irradiation circular hole. The light source board is provided with a plurality of through holes 13. The heat dissipation gap and the space between the support plate and the light source board can be connected, which is conducive to heat conduction and heat dissipation.

[0036] In actual application, the lamp housing is rotatably connected to a bracket 15 via a bolt 14. At the same time, in order to facilitate operation, control and adjustment, an external power connector 16 and a switch button 17 are provided on the lamp housing.

[0037] The present invention has positive effects: the structure of the present invention is reasonably arranged, a heat dissipation gap is arranged between the light source board and the lamp housing, and a fan is arranged in the heat dissipation gap to cooperate with a heat-conducting radiator, which can not only dissipate heat through the heat-conducting radiator, but also can use the fan to dissipate heat at the same time, which is beneficial to improving the heat dissipation performance. At the same time, it not only has a lampshade panel, which can limit the lamp cup lens in the irradiation circular hole, but also has a limiting support plate, which can limit the lamp cup lens to prevent the lamp cup lens from shifting or shaking, which is beneficial to improving the installation stability and reliability of the lamp cup lens, thereby improving the lighting effect and having strong practicality.

[0038] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
