Description
Technical field
The present invention relates to LED illumination bulb technical field, particularly a kind of bulb with single-ended seven substrate LED luminescence units.
Background technology
Compared with conventional tungsten bulb, LED bulb has fast response time, life-span length, energy saving, efficiency advantages of higher, and application is in daily life more and more extensive, but also there is the problem that caloric value is large, point light source of single is little.In order to solve heat dissipation problem, have in existing LED bulb greatly area be with metal or plastics as radiator, only have very little a part of area as light-emitting area, therefore the volume of its overall bulb is much larger than tradition.There are two large drawbacks in existing this LED bulb: one, bulb luminous component area is little, and lighting angle is large not, only has the place of small size to obtain light in the occasion of illumination; Two, because heat radiation needs to increase radiator area, make the size of LED bulb entirety be difficult to accomplish the dimensional requirement of conventional bulb, the occasion use that conventional bulb replaced by all need can not be adapted to.
Summary of the invention
The object of the present invention is to provide a kind of bulb with single-ended seven substrate LED luminescence units, it is the LED bulb that can substitute conventional bulb, and it while the larger light-emitting area of acquisition, can also have good radiating effect; Meanwhile, the light source supporting structure of this bulb is simple, is easy to realize on the basis of the original core column structure of conventional light bulb, reduces the cost of bulb remodeling widely, due to good heat dissipation effect, is conducive to improving bulb security and service life.
The present invention is achieved through the following technical solutions:
A kind of bulb with single-ended seven substrate LED luminescence units, comprise lamp holder 1, LED driver 2, stem stem 3 and cell-shell 5, LED driver 2 is placed in lamp holder 1, the bottom of two interior conductive filament 3-1 of stem stem 3 is connected with two outputs of LED driver 2 respectively, stem stem 3 bottom be placed in cell-shell 5 is sealed with cell-shell 5 bottom and is connected, lamp holder 1 is fixedly connected with cell-shell 5 bottom, and in the upper end of described stem stem 3 two interior conductive filament 3-1, conduction is connected with single-ended seven substrate LED luminescence units 4.
Described single-ended seven substrate LED luminescence units 4 direct chip package by stamping forming aluminium alloy base plate and on this aluminium alloy base plate has the LED point light source 8 or LED strip light source arranged by equidistant points array, become the hexahedro column shape shape of band upper cover by bending, be provided with conducting connection point in these six cylinder bottoms.Six substrates in described seven substrates are shape, rectangle face that size is identical, form positive six cylinders, the Six Point substrate matched with it is provided with at these positive six cylinder upper tops, described six face length square face substrates and a Six Point substrate are same aluminium alloy base plate, be provided with two conducting connection point 7 in described positive six cylinder bottoms, these single-ended seven substrate LED luminescence units 4 are fixedly connected with conductive filament 3-1 upper end interior with stem stem 3 two respectively by described two conducting connection point 7.
Compared with prior art, the present invention has following remarkable result:
The key technology with the bulb of single-ended seven substrate LED luminescence units of the present invention be in advance design and on stamping forming aluminium alloy base plate direct chip package have the LED point light source or LED strip light source arranged by equidistant points array, become the LED luminescence unit of the hexahedro column shape shape of band upper cover by bending, and conduction connects the two interior conductive filament upper ends being bearing in stem stem.Thus, it while the larger light-emitting area of acquisition, can drastically reduce the area the thermal resistance between light source and aluminium base, has good radiating effect, be conducive to the service life and the security that improve this bulb.Simultaneously, the lamp holder of this bulb, stem stem, cell-shell are substantially identical with conventional bulb, therefore its light source supporting structure is very simple, thus reduce the cost of bulb remodeling widely, and then reduce the production cost of this bulb, but also have and realize good radiating effect.This bulb is basically identical with conventional bulb in shape, size, thus, can use in all occasions need replacing conventional bulb.
