HEAT-DISSIPATION LAMP BASE ASSEMBLY AND PHOTOGRAPHIC SOFTBOX
Document Type and Number:
WIPO Patent Application WO/2022/088842
Kind Code:
A1
Abstract:
A heat-dissipation lamp base assembly and a photographic softbox. The heat-dissipation lamp base assembly comprises a lamp base rear cover (10), a lamp base front cover (20), a motor (30), a heat-dissipation fan (40), and a flow guide cover (50). Several through holes (12) are arranged at the bottom of the lamp base rear cover (10). The heat-dissipation fan (40) comprises a fan border (41) and blades (42). The flow guide cover (50) comprises a small-diameter end (51) and a large-diameter end (52). The small-diameter end (51) is located on the side close to the heat-dissipation fan (40), and mates with the fan border (41). An electric light mounting position (21) is arranged in the middle of the lamp base front cover (20). Several air outlets (22) are provided around the electric light mounting position (21). The air outlets (22) are connected to the large-diameter end (52) to form an airflow channel for allowing the through holes (12), the fan border (41), the flow guide cover (50), and the air outlets (22) to be communicated in sequence, so that the airflow generated by the heat-dissipation fan (40) is guided to the periphery of the electric light mounting position (21) along the airflow channel. Good heat-dissipation performance is achieved by using the specific structures and position relation among the lamp base rear cover (10), the lamp base front cover (20), the motor (30) mounted inside an accommodation cavity (11), the heat-dissipation fan (40), and the flow guide cover (50).
