Abstract

The invention discloses a surface-mount device light emitting bulb with a cylindrical heat radiation ring. The surface-mount device light emitting bulb comprises a lamp holder component (2) with a driving component (3), the lamp holder component (2) is connected on a bulb shell (6), the cylindrical heat radiation ring (5.3) is arranged in the bulb shell (6), a surface-mount device light emitting component (1) is arranged on the outer surface of the heat radiation ring (5.3), a wire support (4.1) is arranged in the bulb shell (6), and a plurality of electric connection wires (4.2) connected with the driving component (3) are arranged on the wire support (4.1) and connected with the light emitting component (1). According to the light emitting bulb, a replaceable and standardized independent electric light source with high power can be achieved, light extraction efficiency is improved, the light emitting bulb can be operated in a closed lampshade, and the light emitting bulb is more convenient to assemble structurally and firmer in structure.

Description

technical field [0001] The invention relates to a patch type light bulb with a cylindrical heat radiation ring and an application thereof, which belongs to the technical field of LED lighting. Background technique [0002] The current LED lighting focuses the industry on LED chips. After obtaining LED chips, mid-stream and downstream enterprises need to design packaging, driving, optics, heat dissipation, lamp structure, etc., and finally formed the current general LED lighting industry, especially high-power Lighting, integrated LED light assembly mode. There are six major systemic defects in this assembly mode. ① At the application level, there is a lack of universal interchangeable standardized light sources, and terminal lighting assembly products present too many individual characteristics. ② At the level of industrial structure, centering on LED chips is not the optimal structure for LED lighting, resulting in many complexities and uncertainties in the design and prod...
