The specific embodiment
Combine the accompanying drawing and the specific embodiment that the present invention is further specified at present.
Consult Fig. 1 a, Fig. 1 b and shown in Figure 2; The LED bulb lamp of embodiment comprises: lamp holder spare 1, heat dissipation metal shell 2, paraffin container 31, paraffin (scheming not shown), sealing ring (scheming not shown), LED lamp pearl array base palte 4, leaded light post 5, lampshade 6 and LED driving power circuit (scheming not shown).
Said heat dissipation metal shell 2 is the cup-like containers profiles that are the indent that top end opening face diameter of section is big, the bottom surface diameter is little, helps increasing the contact area with air, increases whole lamp heat loss through convection.Preferably, described heat dissipation metal shell 2 is an aluminium matter, by the moulding of aluminium integrated punching.
Said paraffin container 31 is arranged in the heat dissipation metal shell 2, holding paraffin in the paraffin container 31, and the top end opening of paraffin container 31 is through the sealing ring sealing and cover cover plate 32, makes paraffin in the paraffin container 31 be in the confined space in the paraffin container and does not leak outside.Preferably, be arranged at intervals with a plurality of dividing plates 3101 in the described paraffin container 31, it is partitioned into a plurality of cavity space, be beneficial to radiating effect more.
Have fixed leg on the said lamp holder spare 1, lamp holder spare 1 is pegged graft with heat dissipation metal shell 2 and is fixed, and the fixed leg 1021 of lamp holder spare forms the supporting surface of fixed L ED lamp pearl array base palte 4 in the upper surface of heat dissipation metal shell.Preferably, described lamp holder spare 1 is screwed by a screw socket 11 and is socketed in a lamp holder connector 12 and forms.
Said LED lamp pearl array base palte 4 is fixed on the supporting surface of fixed leg 1201 of lamp holder spare 1 and can contacts with the upper cover plate 32 of paraffin container 31.Concrete fixed leg 1201 is provided with screw, and LED lamp pearl array base palte 4 is provided with screw, through screw LED lamp pearl array base palte 4 is locked at the supporting surface of fixed leg 1201.Like this, the heat of LED lamp pearl array base palte 4 can conduct to paraffin container 31, heat dissipation metal shell 2 and lamp holder spare 1.
Said LED driving power circuit is arranged in lamp holder spare 1 and is positioned at heat dissipation metal shell 2 chambeies, and lampshade 6 is covered on heat dissipation metal shell 2.The heat of LED driving power circuit also can conduct to the external world through paraffin container 31, heat dissipation metal shell 2.
Preferably, consulting shown in Figure 3ly, is the physical circuit schematic diagram of this LED driving power circuit.Described LED driving power circuit comprises: current rectifying and wave filtering circuit, constant-current control circuit and constant-current circuit; The power output end of current rectifying and wave filtering circuit connects the power input of constant-current control circuit; The power output end of current rectifying and wave filtering circuit also is the positive pole of the power output end of LED power driving circuit, and is connected with the positive terminal of each LED series circuit on the LED lamp pearl array base palte; The constant current input of constant-current circuit is as the negative pole of the power output end of LED power driving circuit, and is electrically connected with the negative pole end of each LED series circuit on the LED lamp pearl array base palte; The constant current output head grounding of constant-current circuit; The control end of the constant current control signal output termination constant-current circuit of constant-current control circuit; The feedback signal input of the feedback signal output termination constant-current control circuit of constant-current circuit.
Said LED lamp pearl array base palte 4 is a plurality of LED lamp of an array arrangement pearl (scheming not shown) on the heat-conducting substrate.Fixing leaded light post 5 on each LED lamp pearl; Said leaded light post 5 is to be connected to form by a cylinder 501 and a multiaspect rhombogen 502; The structure of multiaspect rhombogen 502 promptly is the polyhedral structure (the face number of multiaspect rhombogen 502 is relevant with the shape of the angle of the lozenge of each connection and rhombus) that is interconnected formation by a plurality of lozenges (being 4 lozenges at least), and it is good more that the lozenge of multiaspect rhombogen 502 goes out light effect more at most; And each lozenge of multiaspect rhombogen 502 is coated with half perspective half reflection film system; Cylinder 501 is with light leaded light to the multiaspect rhombogen of LED lamp pearl; The half reflection film of partly having an X-rayed on the multiaspect rhombogen is that the light portion that LED lamp pearl is sent transmits, and partial reflection is gone back.Because of the multiaspect rhombogen that is coated with half perspective half reflection film system be positioned at LED lamp pearl above, a part of light transmission that LED sends shines the dead ahead of bulb lamp, a part reaches the luminous purpose of LED bulb lamp full angle through the back of reflected illumination to bulb lamp.
This LED bulb lamp is that the paraffin through the paraffin container 31 in the heat dissipation metal shell 2 carries out heat radiator.Paraffin is a kind of of mineral wax, also is a kind of of pertroleum wax; It is to make slack wax from the lube cut of crude distillation gained through solvent refining, solvent dewaxing or through wax freezing and crystallizing, squeezing dewaxing, again through solvent deoiling, refining and sheet or acicular crystal.Carbon number is about 18～30 hydrocarbon mixture, and key component is linear paraffin (being about 80%～95%), also has on a small quantity with the alkane of indivedual side chains and the monocyclic naphthenes of belt length side chain (both add up to content below 20%).At 47 ℃～64 ℃ fusings, the about 0.9g/cm of density
3It is water insoluble, but dissolves in ether, benzene and some ester.Paraffin also is good heat accumulating, and its specific heat capacity is 2.14～2.9Jg
– 1K
– 1, melting heat is 200～220Jg
– 1Paraffin is noncrystal, thus in the heating process (from solid-state to liquid state again to gaseous state) even if can be always heat absorption---melted.That is because the molecule of this material of paraffin the inside is being done random motion always, and the energy of material is based on that this point just produces.If under the situation that does not increase paraffin, the power of supposing LED is 5W, and this moment, the temperature of shell just reached 47 ℃.We increase LED lamp pearl quantity now, increase the quantity of bulb lamp, and this moment, original heat-dissipating casing can not satisfy the existence temperature of LED; Therefore solid paraffin is placed in the heat-dissipating casing, when the heat-dissipating casing temperature reached fusing point, paraffin began to melt heat absorption; If the luminous shortage of heat that comes out of LED; Paraffin continues the variation of next paraffin form, and then paraffin is just through absorbing the temperature of LED bulb lamp, the temperature when maintaining this state.Therefore under identical situation, have the LED bulb lamp that has paraffin, can accomplish higher power, reach higher brightness, make the LED bulb lamp become possibility as following room lighting.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the present invention that do not break away from appended claims and limited; Can make various variations to the present invention in form with on the details, be protection scope of the present invention.
