Problems solved by technology

Although this structure can realize the heat dissipation effect, it needs to use the fan to forcibly discharge the hot air flow, which not only needs to increase the driving circuit and motor supporting the fan, but also increases the manufacturing cost, and the heat dissipation depends on the fan, and the heat dissipation effect is relatively passive. In addition, the fan Noisy when turning
Furthermore, due to the close distance between the radiator and the light source module, the working environment of the motor and the fan is high in temperature, which is likely to cause failure. At the same time, the high temperature also causes partial melting of the lamp shell

Description

technical field [0001] The invention relates to the technical field of stage lighting, more specifically, to an active radiator with omnidirectional convection and a stage lamp using the radiator. Background technique [0002] In the field of stage lighting, the power of the stage lamps used is usually relatively large, especially the light source part, which often generates a lot of heat during work, which in turn affects the use effect and service life of the lamps. Therefore, it is necessary to dissipate heat and cool the light source part of the stage lamp. [0003] In the prior art, a heat pipe radiator is usually used to achieve heat dissipation, and this kind of radiator must be used in combination with a fan to achieve an ideal heat dissipation effect. Generally, the heat generated by the light source inside the lamp is diffused through the heat pipe radiator, and then the heat is forced out of the lamp through the fan. [0004] The Chinese utility model patent wit...
