Description
Technical field
The utility model relates to field of LED illumination, is specifically related to a kind of LED bay light.
Background technology
The thermal component of LED bay light adopts the aluminium section bar of heronsbill shape usually, but the radiator of LED bay light was middle is in the past solid aluminum, so just cause light fixture weight overweight, and radiating effect is not good.
And for example utility model patent, a kind of LED floodlight number disclosed in CN 203363710 U, the utility model embodiment discloses a kind of LED bulkhead lamp capable, comprise lamp socket, lampshade, multiple LED lamp pearl, circuit board and radiator, described LED lamp bead is packaged on the end face of described radiator, and the end face of the luminescence chip of LED lamp bead inside and described radiator abuts against, the corresponding radiator of each LED lamp pearl, described lamp socket, radiator and circuit board are connected and fixed successively, the middle part of lamp socket and circuit board is equipped with passage makes the middle part of LED bulkhead lamp capable form air convection channel.The overall volume of this LED bulkhead lamp capable is appointed and is so laid particular stress on, and radiating effect is still undesirable simultaneously.
Solid aluminum in the middle of the radiator of the LED bay light of prior art, the weight penalty of the solid aluminum block weight of light fixture entirety.And the effect of aluminium is non-conductive in heat radiation, such one piece of solid aluminum is positioned at the center of radiator, even if there is the small-sized air channel of local also its heat cannot be distributed by cross-ventilated mode, easily causes the heat of light fixture center saturated, thus have influence on the life-span of LED bay light.
And utility model patent, a kind of LED floodlight number disclosed in CN 203363710 U, the utility model embodiment discloses a kind of LED bulkhead lamp capable, and the middle part of its lamp socket and circuit board is equipped with passage makes the middle part of LED bulkhead lamp capable form air convection channel.A thermal conductive surface just very little on lamp socket whole radiator relative to circuit board, thermal conductive surface arranges the effect of air convection channel far away not as good as arranging the effective of air convection channel on radiator, and this way reduces the contact area of thermal conductive surface and radiator on the contrary, affects heat-conducting effect.
The inner hollow of described radiator of the present utility model, and the dividing plate being arranged on described radiator inside is divided into the cavity of multiple lower airway, described cavity comprises the central hot cavity being positioned at center and the hot cavity in periphery surrounding the setting of described central hot cavity, the outer wall of the hot cavity in described periphery offers multiple by the hot air outlet of outside air and described periphery hot cavity UNICOM.First adopt the design of multiple cavity, radiator inside only has very thin cavity wall to be retained owing to playing support effect, so just the weight of radiator to be reduced to minimum on the basis not affecting its radiating effect.Simultaneously this design is in fact covert adds area of dissipation, opposing solid only have an outside radiating surface increase inside and outside have radiating surface, and radiator is relatively thin, make heat can easily by the air of upper and lower convection current to taking away.Secondly all equal lower airway of cavity, cross-ventilated like this effect is just more obvious, and can produce upper and lower temperature difference in cavity when the temperature of radiator rises especially, better accelerates cross-ventilation speed, serves better radiating effect.Moreover hot air outlet be arranged so that add discharge area and passage at convected air, hot-air is made to be discharged radiator faster like this, and Cryogenic air enters in the cavity of radiator from top faster, accelerate convection velocity equally, strengthen radiating effect.The matching design of such cavity and hot air outlet makes the overall weight of radiator decline to a great extent, and radiating effect is increased dramatically.
