Abstract: A photography lamp includes a housing assembly, a heat dissipation assembly, and a light source assembly. The housing assembly includes a lamp barrel and a rear cover, a main air inlet is disposed on the rear cover, and an air outlet grille is disposed on a side wall of the lamp barrel close to the light outlet end. The heat dissipation assembly includes a fan, the air outlet side of the fan is spaced from the light source assembly, a spacing is arranged between the air outlet side of the fan and the light source assembly, and the spacing is always facing the air outlet grille in the direction of the central axis of the lamp barrel. The photography lamp can improve heat dissipation efficiency of photographic lighting fixtures.

Abstract: The present application discloses a microphone, including: a housing; at least two sound-pickup members respectively disposed on the housing; a control circuit board disposed in the housing and in electrical connection to the at least two sound-pickup members respectively; and a switch member configured for triggering the control circuit board to select one or more of the sound-pickup members for collecting an external sound source. The present application addresses the shortcoming that it is necessary to change the direction of the microphone according to the needs of the scene, realizes the flexible selection and configuration of multiple sound-pickup members, and enriches the use scene of the operator. Once the recording site is set up, recordings with different requirements can be realized by switching circuit, so as to reduce the movement of recording equipment, which is suitable for recording equipment such as a camera and a camcorder.

Abstract: The present application relates to the technical field of electronic circuits, and provides a charge circuit, a control box and a luminaire. The charge circuit includes a control circuit and at least one constant current charge circuit. The constant current charge circuit is electrically connected to the rechargeable battery. The control circuit is used to obtain the specification information of the rechargeable battery, and configure the corresponding charging parameters to be sent to the corresponding constant current charge circuit, so as to charge the rechargeable battery through the constant current charge circuit.

Abstract: A lamp includes a housing, a heat sink, a light source and at least a bracket. The heat sink is disposed within the housing. The light source is connected with the heat sink. The bracket is disposed within the housing, and the bracket includes a main body and a first fixing portion arranged along the outer edge of the main body. The main body of the bracket connected to a side surface of the heat sink is connected to the housing through the first fixing portion to dispose the heat sink in the housing. When the bracket is fixedly connected to the inner wall of the housing, the heat sink can be firmly installed inside the housing and it is not easy to loosen during use, so that the heat sink can continuously and stably dissipate for the lamp.

Abstract: A light fixture includes a housing with a hollow inner cavity, and a first ventilation region and a second ventilation region are arranged on the housing; a heat sink disposed in the hollow inner cavity of the housing, wherein the heat sink includes a plurality of fins disposed side-by-side corresponding to the first ventilation region and the second ventilation region; and a blocking mechanism disposed between the heat sink and an inner wall of the housing to divide the hollow inner cavity into a first cavity and a second cavity.
