Specific embodiment

It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this Utility model.

Referring to figs. 1 to Fig. 8, an a kind of embodiment of large stadium downlight of the utility model is proposed, including cylindrical case, In being installed on the rear cover 200 with top groove 201 at the top of cylindrical case, being installed on top groove 201 and for lifting Hanging plate 300, the radiator being installed in cylindrical case, peace are fixed in the bracket 500 of radiator upper end, peace is fixed on bracket 500 simultaneously The driving power 600 kept apart with radiator, is laid on substrate 701 substrate 701 for being tightly attached to radiating bottom plate lower end surface Several LED lamp beads cover in LED lamp bead and play the optical grade reflector 702 of guidance and reflection action to light, are installed on The light-transmitting plate 703 of 702 lower end surface of reflector, the cover 704 for being installed on 703 lower end surface of light-transmitting plate, peace are fixed in 704 upper end of cover First fixed ring 705, peace are fixed in the second fixed ring 706 of radiator lower end, are fixedly arranged on cover 704 and cover at light-transmitting plate Anti-dazzle grille mesh cover 707 at 703 lower end surfaces passes through connecting column 708 between first fixed ring 705 and the second fixed ring 706 It is attached fixed and plays the role of limit admittedly to reflector 702, light-transmitting plate 703.

Wherein, the local location of radiator is contacted with cylindrical case, so that thermally conductive effect of conducting heat is played, so that radiator On heat can promptly spread all over entire cylindrical case in time.

Large stadium downlight is installed with lifting mode, and hanging plate 300, which is installed on ceiling etc. by messenger wire or hanging ring, pacifies On dress face.

The peace of bracket 500 is fixed in radiator upper end, and the peace of driving power 600 is fixed on bracket 500 and keeps apart with radiator, In this way, the big LED lamp bead of the calorific value for being installed on radiator lower end and the big driving power 600 of calorific value are just kept apart, The heat generated each other will not generate interference, effectively prolong the service life.In addition, cylindrical case is blocked by several housing units 101 It inserts and is put together, cylindrical case side wall is equipped with several the first ventilating heat dissipating holes 102 for being connected to inside.Radiator includes heat dissipation Bottom plate, several radiating fins 401 for being riveted on radiating bottom plate and carrying out annular splicing arrangement, if radiating fin 401 is equipped with Dry fin ventilation hole 402, be installed between radiating fin 401 can ventilation and heat ventilation slot 403, radiating bottom plate and radiating fin 401 are made of heat-conducting metal.Rear cover 200 is equipped with several the second ventilating heat dissipating holes 202 for being connected to inside.Cylindrical case, Rear cover 200, cover 704 are made of heat-conducting metal.Such novel and reasonable structure, the first ventilation on cylindrical case side wall dissipate The second ventilating heat dissipating hole 202 on hot hole 102, rear cover 200, the ventilation slot 403 between the radiating fin 401 of radiator, heat dissipation Fin ventilation hole 402 on fin 401 forms criss-cross vent passages, in this way, in cool exterior air and vent passages Hot-air be formed Air Temperature Difference and atmospheric pressure difference to form air-flow, the air of flowing takes away rapidly internal heat Amount takes away rapidly heat by spontaneous air flowing, and radiating efficiency is high.Airflow direction is flexibly random, the above process In, air flowing can take away rapidly internal hot-air, and outside air is quickly exchanged heat, and radiating efficiency is high.It is new in this way The radiator structure of type, structure novel, and it is rationally simple, promote air to flow as power using the temperature difference and draught head, is formed Spontaneous air-flow takes away heat rapidly, radiating efficiency height, good heat dissipation effect, effectively extension LED lamp bead and driving power 600 Service life.In addition, radiating bottom plate is made with radiating fin 401 of heat-conducting metal, moreover, radiating fin 401 and heat dissipation bottom It is that riveting is fixed, and cylindrical case, rear cover 200, cover 704 are also made of heat-conducting metal between plate, in this way, heat can Promptly to spread all over entire radiator or even cylindrical case, rear cover 200, cover 704 in time, the conduction efficiency of heat is very high, Further improve radiating efficiency.

Large stadium downlight further include several peaces be fixed on bracket 500 and rear cover 200 play the role of it is dual anti-fall anti- Chain 800 is fallen, is occurred to prevent installing the small probability event of failure, is ensured using safe, security performance height.

The setting range of the height of reflector 702 is 3.5 centimetres to 3.9 centimetres, and the side wall of reflector 702 is arcwall face, The setting range of the tilt angle of arcwall face is 18 degree to 22 degree.The cup body of this reflector 702 is relatively high narrow so as to light Play the role of multiple reflections, reflectivity is high, and light emitting angle can be made to reduce, and plays the effect for gathering light, forms high density The light-out effect of vertical light out, light utilization is high, and light efficiency is high, and illumination is still enough in the higher situation of mounting height, out Light effect is ideal, meets the lighting demand in the place of various height, applied widely.

Large stadium downlight includes the anti-dazzle grid for being fixedly arranged on cover 704 and covering at 703 lower end surface of light-transmitting plate Mesh enclosure 707 effectively reduces dazzle angle in this way, lateral location of the people below large stadium downlight not can be appreciated that light source, Dazzle interference is substantially reduced, comfortable light environment is made.

Housing unit 101 is in L font, and the side of housing unit 101 is equipped with strip 103, and the other side of housing unit 101 is set There is strip-shaped clamp groove 104 that can be fixed with 103 card insertion of strip, shell is made by the card insertion fixation between strip 103 and strip-shaped clamp groove 104 Body unit 101 splices and combines into the cylindrical case in rectangular shape, splices and combines install convenient, without welding, can flexibly into Row dismounting.

200 inlay card of rear cover in cylindrical case, consolidated by screw mode by the upper surface of rear cover 200 and cylindrical case Fixed, cylindrical case inner sidewall is equipped with several ribs 105, the side wall of the top groove 201 of rear cover 200 and the rib of cylindrical case It is fixed between 105 by screw mode, dual between rear cover 200 and cylindrical case to be connected and fixed, stable connection is firm, peace Full performance is high.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Equivalent structure transformation made by using the description of the utility model and the drawings is applied directly or indirectly in other phases The technical field of pass, is also included in the patent protection scope of the utility model.
