Abstract
The utility model relates to an LED (light emitting diode) lamp assembly, in particularly to a radiating base of an LED bulb. The radiating base comprises a base main body and is characterized in that: the radiating base also comprises a heat conduction sheet and a radiating structure, wherein the heat conduction sheet is connected with an external LED lamp panel; the base main body is particularly a metal conical table, the radiating structure is arranged on the base main body, and the heat conduction sheet is arranged on and connected with a tabletop of the base main body with a larger area in a jointing way. In the above structure, the base main body is designed into the conical table, the heat conduction sheet is arranged on the conical table, and the LED lamp panel is arranged on the heat conduction sheet; in this case, heat can be quickly conducted onto the base main body by the heat conduction sheet; as the base main body is made of metal, the radiation can be quickly realized; therefore, the quick radiating purpose can be achieved. The reasons that the base main body is designed into the conical table are as follows: first, the volume and the cost can be reduced; second, due to such shape, the contact area is large when air flow passes by.
Description
Technical field
The utility model relates to a kind of LED lamp assembly, especially a kind of cooling base of LED bulb.
Background technology
Illuminations is seen everywhere in our daily life, and illuminations is applied in a lot of aspects, throws light on such as interior decoration: wall lamp, pendent lamp, corner lamp, anomaloscope etc.; Special-purpose general lighting: low-level lighting (lamp is used in corridor lamp, doorplate lamp, front yard), microscope lamp, desk lamp etc.; Emergency lighting: mine lamp, explosion-proof lamp, green indicating lamp, emergency light; General lighting: office, shop, hotel, home-use general lighting lamp though the LED illuminations has certain application within the specific limits, are not very extensive; This mainly contains some reason, because principle of luminosity and traditional gaffer of LED lamp have tangible difference, LED (Light EmittingDiode); Being light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity; The heart of present LED lamp pearl is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole; The other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer through lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is by the material decision that forms the P-N knot, though the LED lamp is energy-conservation simultaneously, can accumulate a lot of heats when in use; Because the light-emitting component of LED lamp, temperature influence can cause the difference on the performance; Or even cause damage, therefore aspect heat radiation, to guarantee that not only area of dissipation is big; It is fast that heat conduction is wanted, be product most on the market all area of dissipation is big, but do not reach desirable radiating rate.
Summary of the invention
The utility model provides a kind of cooling base of LED bulb of simple in structure, quick conductive heat radiation.
The utility model solves the technical scheme that its technical problem adopted: a kind of cooling base of LED bulb; Comprise base body; It is characterized in that also comprising being used for the conducting strip, the radiator structure that are connected with the external LED lamp plate, base body is the metal frustum, and radiator structure is arranged on the base body; Conducting strip is arranged on the bigger table top of base body area, is fitted and connected with table top.
This is provided with is arranged to frustum with base body, and the conducting strip that on frustum, is sticked, and the LED lamp plate is arranged on the conducting strip, and conducting strip can conduct heat on the base body fast; Base body is a metal, therefore can dispel the heat fast, reaches the purpose of quick heat radiating; Why base body is frustum, the one, in order to reduce volume, reduce cost; The 2nd, because such shape, when air draught was blown over, the area of contact was big; Though surface area ratio is cylindrical little, when air-flow was arranged, contact area was but greater than cylinder.
Further being set to of the utility model: at the protruding heat radiation platform with the conducting strip shape adaptation of the bigger table top of base body area, conducting strip is arranged on the heat radiation platform, also is provided with louvre on the platform that dispels the heat.
This is arranged on a special heat radiation platform is set on the base body, conducting strip is arranged on the heat radiation platform, and on the heat radiation platform, is provided with louvre, and louvre can make the conducting strip fast cooling, effectively accelerates the speed of heat radiation.
Further being set to of the utility model: on the side surface of base body, be provided with protruding and bonding jumper frustum side surface shape adaptation; The bonding jumper space protrusion; Be arranged on uniformly on the side surface of frustum; Form radiating groove between the adjacent metal bar, bonding jumper, radiating groove constitute radiator structure.
This is arranged on and is provided with the radiator structure that bonding jumper and radiating groove constitute on the side of base body; Not only increased the area of dissipation on base body surface; Radiating groove not only can form air stream simultaneously, also can strengthen the current rate of radiating groove, further accelerates radiating rate; And be wholely set with base body, so just do not deposit the just problem of medium conductivity difference.
Further being set to of the utility model: also comprise the auxiliary heat dissipation chamber, the bonding jumper top exceeds the conducting strip upper surface, forms the outer ring of an annular, and the diameter of outer ring is greater than the size of conducting strip, and the space between the conducting strip forms the auxiliary heat dissipation groove.
This is arranged on and is provided with the auxiliary heat dissipation groove between radiator structure and the conducting strip in addition, not only can let the conducting strip fast cooling, reduces near the temperature the heat radiation platform simultaneously, helps the heat-transfer rate of conducting strip.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
The specific embodiment
Can know with reference to figure 1, a kind of cooling base of LED bulb, base body 1 is the metal frustum; At the protruding heat radiation platform 11 with conducting strip 2 shape adaptation of the bigger table top of base body 1 area, conducting strip 2 is arranged on the heat radiation platform 11, and the platform 11 that dispels the heat is provided with louvre 111; On the side surface of base body 1, be provided with protruding and bonding jumper 12 frustum side surface shape adaptation, bonding jumper 12 space protrusion are arranged on the side surface of frustum uniformly; Form radiating groove 13 between the adjacent metal bar 12; Bonding jumper 12, radiating groove 13 constitute radiator structure, and bonding jumper 12 tops exceed conducting strip 2 upper surfaces, form the outer ring of an annular; The diameter of outer ring is greater than the size of conducting strip 2, and the space between the conducting strip 2 forms auxiliary heat dissipation groove 3.
