The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Fig. 1 is that the utility model electricity-saving lamp radiator structure the first embodiment is applied in the assembling schematic diagram on electricity-saving lamp.This electricity-saving lamp radiator structure comprises upper cover 10, radiating piece 20 and lower cover 30, and this lower cover 30 is fixedly connected with the fluorescent tube 40 of electricity-saving lamp.
Please refer to Fig. 1, Fig. 2, this radiating piece 20 comprises connecting ring 21 and thermal insulation board 22.This connecting ring 21 is circulus, the arc plate structure that this thermal insulation board 22 protrudes out towards this lower cover 30 for middle part.This thermal insulation board 22 is arranged on the middle part of this connecting ring 21 and this connecting ring 21 is separated to form to upper groove body 211 and lower groove 212, this upper groove body 211 and this upper cover 10 are connected to accommodate the drive circuit board (not shown) of this electricity-saving lamp, and this lower groove 212 is fixedly connected with this lower cover 30.This thermal insulation board 22 is provided with through wires hole 221, these through wires holes 221 are communicated with end face and the bottom surface of this thermal insulation board 22, corresponding these through wires holes 221 in bottom surface of this thermal insulation board 22 are provided with the heat insulation round platform 223 of hollow, to avoid the heat that fluorescent tube 40 produces to mix with the cold airflow that enters these drive circuit board 40 bottoms through these filament holes 221, affect radiating effect in uphill process.The madial wall of this upper groove body 211 is provided with support 213, and this drive circuit board is arranged on described support 213, to form enough insulated spaces highly with this thermal insulation board 22, avoids the impact of the thermal current of this fluorescent tube 40.This connecting ring 21 is provided with air admission hole 201 at the position of this upper groove body 211, and these air admission holes 201 are positioned under described support 213, and these air admission holes 201 enter for the cold airflow that makes this electricity-saving lamp outside, to this drive circuit board is carried out to cooling heat dissipation.The middle part of these thermal insulation board 22 bottom surfaces protrudes out and forms thermal conductive surface 222 towards this lower cover 30, this connecting ring 21 at the position of this lower groove 212 to being provided with passage 202 by thermal conductive surface 222, this passage 202 is communicated with the outside of this lower groove 212 and this electricity-saving lamp, the thermal current of this fluorescent tube 40 along the arc curve of this thermal conductive surface 222, and is directedly discharged in time by these passages 202 in uphill process.
In sum, this electricity-saving lamp radiator structure is provided with thermal insulation board 22, and the middle part of these thermal insulation board 22 bottom surfaces protrudes out and forms thermal conductive surface 222 towards this lower cover 30.When work, this thermal insulation board 22 is for the heat that in the heat that intercepts this upper cover 10 drive circuit board (not shown) and produce and this lower cover 30, fluorescent tube 40 produces, and the heat that this drive circuit board produces can be lowered the temperature by the cold airflow that enters these air admission holes 201; The heat that this fluorescent tube 40 produces rises and is dispersed in time space outerpace through these passages 202 along this thermal conductive surface 222, realizes the radiating and cooling to whole lamp.Like this, the middle part of these thermal insulation board 22 bottom surfaces protrudes out and forms thermal conductive surface 222 towards this lower cover 30, not only make this drive circuit board and this thermal insulation board 22 can form the insulated space of enough height, and the heat that this electricity-saving lamp is produced can leave in time, due to without two layers of partition panel are set, thereby greatly reduce the height of this radiating piece 20, make this electricity-saving lamp radiator structure there is compact conformation and good heat dissipation effect, greatly reduce cost.
Understandable, as long as can form the thermal conductive surface 222 that this protrudes out, the shape of these thermal insulation board 22 cross sections can have multiple, the arc that is not limited to protrude out downwards.The effect of the thermal conductive surface 222 that this protrudes out is mainly guiding thermal current, can discharge rapidly, thereby improve radiating efficiency.
