Abstract
The utility model discloses an LED lamp bulb which comprises a rear radiator and a rear cover arranged and connected with the rear radiator, wherein the rear radiator is internally provided with a driving circuit with terminals of penetrating through the rear cover. The rear radiator is provided and connected with a front radiator provided with a blind hole or a blind slot for arranging an LED lamp, the geometric center position of the front radiator is provided with a through hole, the blind slot is arranged on the wall of the through hole and internally provided with the LED lamp with an aluminum base plate, and the LED lamp is covered with lenses which correspond in a one-to-one manner. The LED lamp bulb has reasonable structural layout, strong heat dissipation capability, large power, high brightness and low processing cost, and can be arranged on a plurality of LED lamps.
Description
Technical field
The utility model relates to a kind of bulb, the LED bulb that specifically a kind of heat-sinking capability is strong.
Background technology
The LED lamp is compared with conventional incandescent or sight lamp, has advantages such as long, low in energy consumption, energy-conserving and environment-protective of life-span, and therefore, the LED lamp has obtained more and more widely use as lighting bulb.In the prior art, the radiator in the LED bulb has only one usually, and LED and lens all concentrate in the radiator, and the radiator space is little, and thermal diffusivity is relatively poor, and the bulb overall power is not high, can't obtain higher brightness.Existing LED bulb heat radiation body generally has two kinds of production technologies, and one is aluminium alloy compression casting, and the 2nd, the turning processing of aluminium alloy extruded back.The radiator area of dissipation of aluminum alloy die-casting technological processing is little, and radiating efficiency is low; The radiator of aluminium alloy extruded back turning processing, area of dissipation is big, but the contact area of radiator that this kind mode is processed and aluminium base is little, and heat can not in time pass to radiator from aluminium base smoothly, and heat transfer efficiency is poor, and turning processing charges costliness.
The utility model content
The technical problem that this practicality solves provides the LED bulb that a kind of heat-sinking capability is strong, power is high, processing cost is low.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
The LED bulb comprises that the back radiator reaches and the bonnet of this back radiator attaching, and the interspersed drive circuit of lid later of terminals is housed in the back radiator.Attaching has preceding radiator on the radiator of described back, offers the blind hole or the blind groove that are used to install the LED lamp on this preceding radiator.
The geometric center position of radiator has through hole before described, and blind groove is located on the hole wall of this through hole, and the LED lamp of band aluminium base is housed in this blind groove, is covered with lens one to one on this LED lamp.
For better heat radiation, on the upper surface of back radiator, be provided with the convex of the through hole on the radiator before passing, this convex aluminium base interior with being loaded on blind groove contacts.For more excellent design, the cross section of the blind groove on the described preceding radiator is major arc shape.
For further heat radiation, on preceding radiator and back radiator, be equipped with fin.
The utility model topology layout is reasonable, has increased preceding radiator on the basis of original back radiator, and preceding radiator dispels the heat to most of heat of bulb, strengthened the thermal diffusivity of bulb greatly, make the radiating effect of bulb better, effectively improve the power of bulb, make the brightness of bulb higher.Because the radiating efficiency height of radiator, under the situation of identical heat, the weight of required radiator significantly reduces, thereby makes that the overall weight of bulb is lighter.In addition, the utility model utilizes pack alloy processes radiator, has reduced the turning processing charges, and manufacturing cost is lower.
Description of drawings
Accompanying drawing 1 is the utility model perspective view; Accompanying drawing 2 is the utility model decomposing state structural representation.
The specific embodiment
For global those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
Shown in accompanying drawing 1,2, a kind of LED bulb comprises that back radiator 1 reaches and the bonnet 2 of this back radiator 1 attaching, and the drive circuit 3 that terminals pass bonnet 2 is housed in the back radiator 1, radiator 4 before attaching has on the radiator 1 of back has blind hole or blind groove 41 on this preceding radiator 4.Geometric center position at preceding radiator 4 has through hole, and blind groove 41 is located on the hole wall of this through hole, and the LED lamp 52 of band aluminium base 51 is housed in the blind groove 41, is covered with lens 53 one to one on this LED lamp 52.For the optimization of structure, the cross section of blind groove 41 is made as major arc shape.In order to improve heat-sinking capability, on the upper surface of back radiator 1, be provided with the convex 6 of the through hole on the radiator 4 before passing, this convex 6 passes through hole and contacts with aluminium base 51.The heat that 4 pairs of LED lamps of preceding radiator produce can pass to back radiator 1 by convex 6 and dispel the heat, and is dispelled the heat simultaneously by forward and backward two radiators, and radiating effect is better.In addition, in order further to improve the heat-sinking capability of radiator, on preceding radiator 4 and back radiator 1, be equipped with fin 7.Before the connected mode of radiator 4 and 1 of back radiator, both can be the screw thread mode that spins, also can be the mode of bolting, or other connected modes, according to the actual conditions setting, the above-mentioned connected mode of mentioning not is to be to qualification of the present utility model.
Need to prove that under the prerequisite that does not break away from the present utility model design, any conspicuous variation or the replacement that is equal to are all within protection domain of the present utility model.
