Description
Technical field
The invention belongs to the LED lighting technical field, particularly relate to a kind of LED lamp staggered form radiator.
Background technology
The not only energy-saving and environmental protection of LED lighting engineering have also that the life-span is long, volume is little, safe, photochromic characteristics such as abundant, easy to control.The LED illumination is the key core technology of little by little having grasped few in number, has market demand prospect, possesses the strategic new industry that the resource energy consumption is low, drive the features such as coefficient is large, job opportunity is many, comprehensive benefit is good.It has not only brought the revolution of another lighting source after incandescent lamp, fluorescent lamp on the illumination history, and is the important channel of energy-saving and emission-reduction, will bring into play more importantly effect to the development low-carbon economy.Therefore, the relevant application product of LED illumination is all done one's utmost to develop by each manufacturer.
But there is a very large heat radiation difficult problem in the LED lamp.Heat dissipation problem is the bottleneck of LED lamp in illumination is used always, is never effectively solved.LED has relatively high expectations to heat dissipation technology, and the temperature of LED lamp chip sharply rises when the effect of radiator is bad, can produce very soon light decay, even damages LED chip.The temperature of the higher chip of heat flow density of LED chip rises faster, only has the heat dissipation technology that solves LED, delays to greatest extent the light decay of LED, just can embody long advantage of life-span, makes LED become real in the large-area applications of indoor and outdoor lighting.
The heat radiation of current LED lamp or module is mostly adopted die-casting die and section bar heronsbill radiator or is adopted aluminium ingot Digit Control Machine Tool processing heat radiator and hot pipe technique.This die-casting die radiator heat-dissipation weak effect, volume is also larger.The geometry of heronsbill structure radiator is fixing, and fin density is little, is difficult for heat radiation, easy dust stratification dirt in fin.
Driving power on existing LED light fixture is contained in inside radiator, does not carry out insulation and heat insulating construction measure, and causes that the heat of LED driving power itself has increased, and just reduced the service life of this power supply.Produce again simultaneously the raising of the temperature rise of radiator, cause the temperature of LED lamp raise and produce serious light decay.
Summary of the invention
Be the planform of early settlement LED lamp radiator and the raising of radiating effect, and the electric insulation of the heat dissipation problem of LED driving power and radiator and heat-insulating problem, the invention provides a kind of LED lamp staggered form radiator.
The technical solution adopted for the present invention to solve the technical problems is: comprise heat transfer plate, fin, conducting strip, fin, lamp holder, mains isolation shell, LED power panel, thermal insulation board and LED aluminium base, when forming the LED light fixture of semiconductor lighting, with being fixed with the LED aluminium base of LED lamp, be fixed in bolt above the aluminium base fixing hole of heat transfer plate.
Technical characterictic of the present invention is: be provided with fin, conducting strip and fin on heat transfer plate He on every side, wherein fin and conducting strip are combined into one group, and with the fin ordered arrangement of being separated by.
Be arranged between 2 conducting strips at the fin on heat transfer plate, fin and arrangement mode between fin have parallel or uneven; Several fin form one group, and with the not parallel arrangement of fin, but with fin between parallel or uneven arrangement are arranged.
Also have side view at the fin on heat transfer plate and fin be from hem width begin down to narrow down; The side view of fin is that narrow beginning down broadens from the top, consists of staggered form radiator shape with this.
The LED power panel is surrounded by metallic lamp holder, mains isolation shell and thermal insulation board, and the fixing hole of mains isolation shell and thermal insulation board are connected with screw or bayonet socket.
The LED power panel is electrically connected to metallic lamp holder, the direct current output electric wire of LED power panel, through the fairlead that is connected with the thermal insulation board bottom surface and the wire hole of heat transfer plate, be electrically connected to the LED aluminium base, the heat of LED power panel distributes by the louvre on the mains isolation shell or metallic lamp holder.
The unsettled pillar of several that connect below thermal insulation board is positioned over above the screw hole of fin, and fixes with bolt; The fairlead cross section that connects below thermal insulation board, by the wire hole that has on heat transfer plate, should be concordant with the plane of LED aluminium base, and seal heat transfer plate by lampshade.
LED light fixture specification kind of light fixture when practical application is a lot, so the outside geomery of staggered form radiator can be changed, so that the light fixture of different size can be selected suitable shape, improves radiating effect.
The invention has the beneficial effects as follows, be connected owing to being connected with fin with fin, conducting strip at heat transfer plate recessed position, reduced the thermal resistance of heat transfer plate, the heat of LED aluminium base is conducted to fin, fin and fin very soon by heat transfer plate, and carry out heat loss through convection with surrounding air, thereby reduce the temperature rise that the LED lamp produces; Be provided with thermal insulation board on the staggered form radiator, LED power panel and staggered form radiator heat are isolated and are independent of each other thus, guarantee the security performance of light fixture, and the temperature of reduction LED power panel, the service life in prolongation electronic devices and components life-span, particularly electrolytic capacitor, improved its functional reliability, being suitable for corridor, corridor and underground garage etc. has dust, and environment temperature is higher, and the occasion of maintenance difficult is used.
Due to fairlead the metals such as power line and staggered form radiator isolation, so do not have the worry of electric shock during mounted lamp and use in tactile thermal phenomenon, and the electric insulation and the heat that are particularly suitable for high voltage LED application luminaire are isolated.
Secondly advantage is, this staggered form heat spreader structures is compact, adopts the good aluminium material of thermal conductivity, is integral with extrusion process, reduces processing cost.
