The specific embodiment
Describe the utility model in detail according to accompanying drawing and embodiment below, it is more obvious that purpose of the utility model and effect will become.
Embodiment 1
As shown in Figure 1, the utlity model has duct formula heat loss through convection LED channels lamp, comprise lamp holder 1, heat radiation lamp body 2, led light source 5, luminous intensity distribution lampshade 6, dividing plate 11 and drive circuit 12; Heat radiation lamp body 2 is hollow and annular, and the upper end is connected with lamp holder 1; Heat radiation lamp body 2, lamp holder 1 and dividing plate 11 form a cavity, and drive circuit 12 is positioned at this cavity, and an end connects lamp holder 1, and the other end connects led light source 5; Led light source 5 is distributed in Heat radiation lamp holder 2 bottoms ringwise, and covers sealing by luminous intensity distribution lampshade 6.
Described Heat radiation lamp holder 2 is processed by metal, plastics etc., in be provided with endoporus 3 and some passages 4 that link to each other with endoporus 3; Passage 4 is communicated with endoporus 3 and Heat radiation lamp holder 2 outer surfaces, and endoporus 3 surfaces are provided with interior radiating fin 8, and Heat radiation lamp holder 2 outer surfaces are provided with outer radiating fin 9.
Described luminous intensity distribution lampshade 6 is a kind of even light modulation cover or light-distribution lens of being processed by optical material, and ringwise, the centre has an outer hole 7.
Described outer hole 7 is communicated with duct of formation with endoporus 3, duct communicates with passage 4 and forms the heat loss through convection passage.
As shown in Figure 2, the duct of being made up of endoporus 3 and outer hole 7 is positioned at heat radiation lamp body 2 and luminous intensity distribution lampshade 6 centers, the overwhelming majority of passing whole luminous intensity distribution lampshade 6 and heat radiation lamp body 2; And be connected with all side passages 4, light fixture in use, natural convection air forms stack effect in duct and passage 4; Stack effect is meant, after air in the duct is heated intensification, rises along duct; And leave through passage 4, the duct internal gas pressure reduces, and makes air outside outer hole 7, get into and replenishes; More make air flow faster in the duct, quicken the lamp body heat radiation.
Embodiment 2
