Description

Technical Field

[0001] The utility model relates to the technical field of stage light processing, in particular to a heat dissipation system for a small-volume stage light. Background Art

[0002] In the existing market, the general length and width of large-volume stage lights are 590 and 336 millimeters, while the size of small-volume stage lights is 539 and 296. However, the light sources used in both types of stage lights are 1000W light sources. The light flux output of large-volume stage lights is about 35000LM, while the light source of small-volume stage lights is a 1000W LED high-density light source, and the light flux output of the whole lamp can reach about 51000LM. High output means high heat generation, and enhancing heat dissipation corresponds to increased noise. If the noise is too high, it will also affect the stage effect. Therefore, there is a need for a heat dissipation system suitable for small-volume stage lights that can be flexibly adjusted according to the actual use environment to achieve the stage light effect while taking noise into account. Content of the Utility Model

[0003] The present disclosure provides a heat dissipation system for a small-volume stage light. The heat dissipation control main board controls the rotation speed, start and stop of the front air blower, rear air blower, total heat dissipation air blower, CMY heat dissipation structure, cutter and pattern disc heat dissipation structure, and light source heat dissipation structure, as well as the brightness of the light source according to actual needs, which can be flexibly adjusted according to the actual use environment to achieve the stage light effect while taking noise into account, ensuring that components will not be damaged under high-temperature conditions and enabling the whole lamp to operate normally for a long time.

[0004] In order to achieve the above-mentioned utility model purpose, the present utility model provides the following technical solutions:

[0005] A heat dissipation system for a small-volume stage light, including a stage light main body. There are a front air inlet, a hot air exhaust outlet, and a rear air inlet provided on the outer shell of the stage light main body. Inside the stage light main body, there are a heat dissipation control main board, a light source, a front air blower, a rear air blower, a total heat dissipation air blower, a CMY heat dissipation structure, a cutter and a pattern disc heat dissipation structure, and a light source heat dissipation structure. The front air blower is aligned with the front air inlet, the rear air blower is aligned with the rear air inlet, and the total heat dissipation air blower is aligned with the hot air exhaust outlet. The heat dissipation control main board controls the rotation speed, start and stop of the front air blower, rear air blower, total heat dissipation air blower, CMY heat dissipation structure, cutter and pattern disc heat dissipation structure, and light source heat dissipation structure, as well as the brightness of the light source according to actual needs.

[0006] Preferably, the CMY heat dissipation structure is set as a CMY heat dissipation fan, and the CMY heat dissipation fan dissipates heat from the CMY color filter, and the heat dissipation control main board can adjust the rotation speed of the CMY heat dissipation fan as needed.

[0007] Preferably, the cutter and pattern disc heat dissipation structure is provided as a cutter and pattern disc cooling fan, and the cutter and pattern disc cooling fan dissipates heat from the cutter and pattern disc. The heat dissipation control main board can adjust the rotation speed of the cutter and pattern disc cooling fan as needed.

[0008] Preferably, the light source heat dissipation structure includes a first lamp body hot air discharge fan and a second lamp body hot air discharge fan. The first lamp body hot air discharge fan and the second lamp body hot air discharge fan are respectively arranged on both sides of the light source to extract the hot air generated by the light source. The heat dissipation control main board can adjust the rotation speeds of the first lamp body hot air discharge fan and the second lamp body hot air discharge fan as needed. When high-brightness projection is not required, the rotation speeds of the first lamp body hot air discharge fan and the second lamp body hot air discharge fan can be reduced, thereby effectively reducing noise.

[0009] Preferably, the light source heat dissipation structure is further provided with a light source heat dissipation pipe. The light source heat dissipation pipe absorbs the heat of the light source. The rear inlet fan is directly opposite to the light source heat dissipation pipe, and the air inhaled by the rear inlet fan passes through the light source heat dissipation pipe, directly dissipating heat from the light source heat dissipation pipe, forming an air-cooled heat dissipation structure, which can effectively assist the first lamp body hot air discharge fan and the second lamp body hot air discharge fan in dissipating heat from the light source.

[0010] Preferably, the light source heat dissipation pipe is a copper pipe. Copper has a high thermal conductivity and a suitable price, and is suitable for industrial mass production.

[0011] The beneficial effects of the present utility model are as follows:

[0012] The present utility model is provided with front and rear air inlets. The outside air is inhaled into the stage light through the front inlet fan and the rear inlet fan for heat dissipation. A hot air exhaust port is arranged in the middle of the stage light. The air passing through the stage light absorbs the heat dissipated by each component of the stage light, and the generated hot air is discharged through the hot air exhaust port by the total cooling fan, realizing a primary heat dissipation air duct cycle;

[0013] Secondly, the utility model is also provided with a heat dissipation control main board, which can respectively control the rotation speed, start and stop of the forward fan, the backward fan, the total heat dissipation fan, the CMY heat dissipation structure, the cutter and the pattern disc heat dissipation structure, and the light source heat dissipation structure according to actual needs, as well as the brightness of the light source. When the user pursues high-brightness projection, the brightness of the light source is turned to the maximum, and the rotation speed of the light source heat dissipation structure is increased to the maximum. Considering the noise problem, the rotation speeds of the other heat dissipation structures can be correspondingly reduced, which can not only meet the required illumination brightness of the user, but also avoid excessive noise. When the user needs to use other functions to create effects, for example, when a part of the light needs to be trimmed on the projected stage, the slicing function of the cutter will be started. Due to the high-density LED light source with high brightness, the temperature at the focal point is very high. When the cutting piece trims the light at the focal point for a long time, it is easy to be burned through after high-temperature oxidation. At this time, the heat dissipation control main board controls to increase the wind speed of the fan and simultaneously reduce the luminous brightness of the light source to reduce the temperature and noise, and solve the heat dissipation problem of the cutting piece. When using the glass pattern piece and CMY color piece for color mixing, the heat dissipation control main board continuously controls according to needs to ensure that the components will not be damaged under high-temperature conditions, and can enable the entire lamp to operate normally for a long time.
