A kind of LED package support
The present invention relates to a kind of mounting bracket of LED, especially relate to a kind of LED package support.
LED (LightEmittingDiode), light-emitting diode, be a kind of solid-state semiconductor device, it directly can be converted into light electricity.The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a support, and one end is negative pole, and the other end connects the positive pole of power supply, makes whole wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is P type semiconductor, and inside it, occupy an leading position in hole, and the other end is N type semiconductor, at this side mainly electronics.But time these two kinds of semiconductors couple together, between them, just form one " P-N junction ".When electric current acts on this wafer by wire time, electronics will be pushed to P district, and in P district, electronics is with hole-recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is.And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction.
Practical and the commercialization of high performance lED, makes lighting technology face a new revolution.The pixel lamp be made up of red, blue, the green three-color LED of multiple super brightness not only can send the continuously adjustable various coloured light of wavelength, but also the white light that brightness can reach tens to one hundred candle light can be sent become lighting source, for incandescent lamp and the LED solid lighting lamp of identical luminosity, the power consumption of the latter only accounts for the former 10%-20%.
The white light LEDs major part of current production is made by covering the faint yellow fluorescent coating of one deck on blue-ray LED, and this yellow phosphor is normally made by being blended in a kind of dense adhesive after the yag crystal mixing cerium is clayed into power.When LED chip sends blue light, some blue light just can be converted to the wider light being mainly yellow of a spectrum by this crystal very efficiently, because gold-tinted can stimulate ruddiness in naked eyes and green glow acceptor, then mix the blue light of LED itself, make it seem just as white light.
Existing LED is generally be directly installed on mounting panel, mounting panel is generally laminated structure, comprise three layers: the line layer being used for connecting up under the heat dissipating layer being used for dispelling the heat, the insulating barrier being used under heat dissipating layer insulating, insulating barrier, wherein heat dissipating layer is generally aluminium foil or aluminum alloy sheet; Line layer is generally Copper Foil and makes, and is used for doing configuration.LED is arranged on heat dissipating layer, welds with line layer.The mounting panel heat dispersion of the LED of this type depends on the thermal conductance index of insulating barrier to a great extent, and the thermal conductance index of insulating barrier is often not high, causes the heat dispersion of whole LED installation strip not good.
Optimal situation is exactly that whole LED mounting panel only has one deck, and that is exactly heat dissipating layer, and LED is welded direct on LED mounting panel, could dispel the heat better like this.Owing to eliminating insulating barrier and line layer, the energising of LED can only be connected by electric wire.If but electric wire distribution on a mounting board, because LED can produce a large amount of heat in luminescence process, the insulating barrier of electric wire appearance will be heated thawing, thus causes open circuit, even can lead to a disaster.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention proposes a kind of LED package support and comprises:
The many substrate bands be arranged in parallel;
Every bar substrate band comprises the first wire, the second wire and thermal wire, wherein said first wire, the second wire and thermal wire be arranged in parallel, substrate band longitudinal direction compartment of terrain is provided with luminous zone and radiating area, in luminous zone, the first wire is symmetrically arranged inverted "L" shaped, and the thermal wire of radiating area has the arc protruded downwards;
Described luminous zone is provided with LED seat, and LED seat top is provided with LED lamp cup, and described first wire, the second wire and thermal conductive wire through described LED seat, and are positioned at the bottom of described Lamp cup.
Further, be circular, and upwards arc-shaped expands gradually bottom described Lamp cup, its top opening is circular, and edge of opening has projection upwards.
Further, described thermal wire has through hole in the part of luminous zone.
Further, described thermal wire is in the part of radiating area, and its arc protruded is the trapezoidal of protrusion.
Further, described thermal wire is in the part of radiating area, and described protrusion arc comprises recessed slope and recessed base plate.
Further, described its material of LED package support is copper or aluminium.
LED package support of the present invention, has many substrate bands, and substrate band is used for mounted LED lamp, does not re-use insulated conductor and connects, but directly connect between each LED; Add thermal wire, the arc to lower convexity of thermal wire in its radiating area can be connected by soldering or the like on fin, makes the heat dispersion of substrate band better; Lamp cup on LED seat directly can inject fluorescent material and mould top glue mixture forms LED lens, and substrate band forms LED string with LED seat together with LED lens.
