Accompanying drawing explanation
Fig. 1 is the explosive view of the bright fitted tube lamp of square of the utility model one embodiment.
Fig. 2 is the stereogram of radiator.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the bright fitted tube lamp of the utility model square is described in further detail.
As shown in Figure 1, in one preferred embodiment, the bright fitted tube lamp 10 of square of the present utility model mainly comprises the lamp body 9 of the tubular that is substantially square, the radiator 6 be fixed in lamp body 9, light source pressing plate 8, LED light source 7, fan 20, power supply 5, reflector 10 and is fixed on protecgulum 11 and the bonnet 2 at lamp body 9 two ends.
Wherein, radiator 6 to be fixed on inside lamp body 9 by medium position, lamp body inner chamber is divided into for hold light source 7, reflector 10 light-source chamber and be used for holding the power source cavity of power supply 5.Weld again a back shroud 4 in power source cavity, power source cavity is divided into two parts.Back shroud 4 is fixed with power supply 5 and for the flat terminal board 3 of fixed power source line in the one side of bonnet 2.Back shroud 4 center has through hole, and ringwise, the aperture at its center is identical or bigger with back shroud 4 middle aperture for power supply 5.In order to ventilate, the bonnet 2 of covering power source cavity also has air vent.Back shroud 4 four angles have been screwed four hexagonal screw rods 14.
The fin 62 that radiator 6 comprises the centerbody 61 in filled circles column and extends radially from centerbody 61 sidewall one, fin 62 end line is substantially rounded.Wherein, the end of relative with in the middle part of each sidewall of lamp body 9 fin is formed with the contact chip 63 parallel with lamp body sidewall.Preferably, lamp body 9 is that the metal material that heat dispersion is good is made.Each contact chip 63 is closely affixed with lamp body sidewall, thus by the heat conduction on radiator 6 to lamp body 9, makes lamp body 9 become a part for lamp radiator, improves light fixture integral heat sink efficiency.The end extended towards corner in lamp body 9 of radiator 6 is formed with the contact chip 65 matched with sidewall and screw rod 14 surface, contact chip 65 is substantially in M shape, thus can be affixed with lamp body sidewall and screw rod 14 surface, and to screw rod 14 in gripping shape, playing effect that radiator 6 is located and the heat of radiator 6 being passed to the effect of lamp body 9.
What LED light source 7 was fixed on centerbody 61 by the light source pressing plate 8 that middle part has a through hole is positioned in the one side of light-source chamber, and bottom and radiator 6 close contact, to reach best heat trnasfer.Two fixed legs are extended in one end of reflector 10, insert in the fixing hole on light source pressing plate 8.Protecgulum 11 comprise the tabular that is square base lid 111 and from the outward extending sidewall 112 of base lid 111 edge-perpendicular.Have the hole that diameter is less than reflector 10 external diameter in the middle part of base lid 111, its corner is provided with fixing hole, is fixed on the hexagonal screw rod end of lamp body 9 four jiaos, is limited between light source pressing plate 8 and base lid 111 by reflector 10 by screw head.Sidewall 112 is transparent PC plate, and make light fixture profile more attractive in appearance, the hot spot of formation is more characteristic.
What fan 20 was fixed on centerbody 61 is positioned in the one side of power source cavity, and it is rounded, and external diameter is greater than the diameter of centerbody 61, but is less than the diameter of a circle that fin periphery forms.Thus by the gap between fin 62 by the suction power source cavity as early as possible of the hot-air in light-source chamber, then discharge lamp body 9 by the hole in the middle part of back shroud 4 and power supply 5 and the air vent on bonnet 2.
Square of the present utility model bright fitted tube light fixture has the advantage that structural reduction, good looking appearance, radiating efficiency are high.In work, the heat of LED chip can distribute quickly through radiator and fan, also distributes by shell body, and heat radiation volume is large, and radiating efficiency is high, thus realizes the object that light fixture bulk life time more lengthens.And the built-in design of LED drive power, maintenance and the installation cost of user can be greatly reduced, improve the installation effectiveness of light fixture, for consumer and market provide the square bright fitted tube lamp of a safer, efficient LED.
Although carry out in conjunction with above specific embodiment description of the present utility model, those skilled in the art can carry out many replacements, modifications and variations, be apparent according to above-mentioned content.Therefore, all like this substitute, improve and change be all included in the spirit and scope of attached claim.
