Description

The structure of lighting device

Technical field

The utility model provides a kind of structure of lighting device; Especially refer to that pedestal is shaped to thin slice with heat-conducting and is the pattern of spool; And be installed in the accommodation space of the enclosure of processing by the light weight material, reach auxiliary light emission module quick heat radiating and light-weighted effect.

Background technology

Environmental consciousness is surging now, various devices and facility mostly all with save the energy, direction that efficient is high develops.On lighting apparatus, the past, its extremely low luminous efficiency made power consumption high by the bulb of widely using; And produce too high used heat during running, make the disintegration of filament cause damage rate to rise easily, and another is by the fluorescent tube of widely using; The situation of flicker also can influence illuminating effect when it was luminous; No matter and be bulb or fluorescent tube, main material is glass, breaks accidentally because of dismounting or carrying easily and causes danger; And after fluorescent tube broke, inner poisonous material was dissipated to the outside and also can pollutes.At present existingly replaces the trend of above-mentioned bulb and fluorescent tube,, meet environmental protection requirement, and main material is plastic cement because of light emitting diode has the advantage of the enough and power saving of brightness with light emitting diode, during dismounting also than safe ready.Please consult Fig. 8 and shown in Figure 9 simultaneously; The three-dimensional exploded view and the heat that are respectively prior art embodiment pass sketch map; The lighting device that is disclosed among its figure is for having radiating seat A, light-emitting diode (LED) module B and shell C; Its radiating seat A is to be the semicircular aluminium matter of hollow body through processing section after the aluminium extruded processing, and forms substrate A1 in its planomural face, and these substrate two sides are respectively equipped with button rail A2; And the side in addition of substrate A1 forms the heat radiation wall A3 of semi arch; And be equiped with light-emitting diode (LED) module B in substrate A1 outer surface, and again the lampshade C1 of the shell C raised line C11 buckle through being convexly set in lampshade C1 two sides is respectively buckled rail A1 in two, at last radiating seat A and lampshade C1 two sides are covered with lid C2 lid respectively; When light-emitting diode (LED) module B operated, the hot part that it sent diffused to the lampshade direction, and another part then can conduct to substrate A1; The heat of this part continues to conduct to heat radiation wall A3 along two button rail A2, and the heat of some is brought to the inner hollow part of radiating seat A through cross-ventilation in addition, yet the tube wall of radiating seat A has certain thickness; Heat conducting poor effect, and the inner hollow part of radiating seat A do not have external outlet, and hot gas is accumulated in the radiating seat A; Can't effectively heat be reached heat radiation wall A3 and be dissipated to the outside; Cause radiating effect not good, make lighting device be prone to burn, if promote the heat dissipation of this kind structure; Then more material must be used, the volume and the weight of lighting device will be increased again.

Therefore, how to solve present lighting device radiating effect not good problem and puzzlement, and the disappearance and the inconvenience that cause lighting device to burn easily, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Therefore, the creator is because above-mentioned problem and disappearance is to collect related data; Via assessing in many ways and considering; And to engage in the many years of experience of the industry accumulation, via constantly studying and revising, the beginning is designed the novel patent birth of novel practical that this kind can reduce lighting device weight.
