Description

LED light source packaging structure Technical Field The utility model relates to the technical field of illumination, in particular to an LED light source packaging structure. Background The development of the LED light source packaging structure is derived from multiple demands of the semiconductor lighting technology on light efficiency, heat dissipation and reliability, the early-stage pin type packaging is only suitable for a low-power scene due to heat dissipation limitation, and along with the popularization of solid-state lighting, the application of the high-power LED in the fields of lighting, display and the like promotes the iteration of the packaging technology. In the existing LED light source packaging technology, the traditional radiating modes such as radiating fins and heat pipes are limited by the heat conduction performance and the surface area of materials, the thermal resistance is high in a high-power scene, the existing radiating structure cannot be stored and folded, the occupied space is large, the application of LED equipment in a portable and compact scene is severely limited, and the fixed radiating structure cannot be dynamically adjusted in a low-power use scene, so that the material waste and the cost are increased, and therefore the LED light source packaging structure is provided. Disclosure of utility model The utility model aims to provide an LED light source packaging structure for solving the problems in the background technology. In order to achieve the above purpose, the utility model provides a LED light source packaging structure, which comprises a substrate, a lamp wick arranged at the top of the substrate, and further comprises: The packaging assembly comprises a support frame connected to the top of the substrate, a packaging plate is arranged at the top of the support frame, and sealant is arranged at the joint between the packaging plate and the support frame; the heat dissipation assembly comprises a shell arranged at the top of the packaging plate, and the shell is connected with heat dissipation fins in a sliding manner; The temperature control driving assembly comprises a bimetallic strip arranged in the shell, a push rod is connected to the bimetallic strip, and the push rod is connected with the radiating fins.
