Abstract

The invention discloses a groove type radiator for an LED lamp, which comprises groove heat transmission bodies, rib fins, radiating fins, fins and isolation boards. During the assembly of the LED lamp, LED aluminum substrates where the LED lamp is fixed are fixed on planes in the groove heat transmission bodies through bolts and electrically connected with an LED power supply box. The groove type radiator is characterized in that a plurality of groove heat transmission bodies are sequentially connected to form an annular body; the rib fins, the radiating fins and the fins are arranged on the periphery and the upper sides of the annular groove heat transmission bodies; and a central ventilation opening is formed in the center of the annular groove heat transmission bodies. The groove type radiator for the LED lamp has the advantages that the ventilation opening is formed in the center of an inner ring formed by the annular groove heat transmission bodies, and heat of the groove heat transmission bodies can be dissipated by air convection through the ventilation opening, so that the temperature rise generated by the LED lamp is further reduced, and the groove type radiator is suitable for being used in the LED lamp used in dusty and high places with higher temperature and difficulty in maintenance, such as storerooms, workshops and the like.

Description

LED lamp fluted body radiator

Technical field

The invention belongs to the LED lighting technical field, particularly relate to a kind of LED lamp fluted body 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, so that LED becomes 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 the fin.

Driving power on the existing LED light fixture is contained in the radiator the inside, 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 rising of LED lamp 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 heat dissipation problem of LED driving power and heat-insulating problem, the invention provides a kind of LED lamp fluted body radiator.

The technical solution adopted for the present invention to solve the technical problems is: comprise groove thermal conductor, fin, fin, fin and division board, when forming the LED light fixture, to be fixed with the LED aluminium base of LED lamp, be fixed on the plane in the groove thermal conductor with bolt, and be electrically connected with the LED power pack.

Technical characterictic of the present invention is: a plurality of groove thermal conductors are connected successively and circularize body, the outside of annular groove thermal conductor and above be provided with fin, fin and fin, and the heart is provided with the central ventilation mouth therein.

Fin both sides on the groove thermal conductor are provided with fin, and are provided with fixing hole at fin, and are connected with fin, and being arranged with of fin and fin is parallel or uneven; Between the fin on the groove thermal conductor, be arranged in parallel, but isolated by the fin group between groups of fins and another groups of fins, and arrange in not parallel mode.

Be provided with division board in groove thermal conductor inboard in addition, and form the annular thermal conductor that a plurality of groove thermal conductors link to each other and are connected into successively with this, and in the groove thermal conductor, be fixed with the LED aluminium base.

The LED power pack is connected with bolt, and is electrically connected with the LED aluminium base by the direct current of LED power pack by the fixing hole of isolation pillar and fluted body radiator.

Light-emitting area at the groove thermal conductor that is fixed with the LED aluminium base covers lampshade, and fixes lampshade by large annular press strip and little annular press strip.

LED light fixture specification kind of light fixture when practical application is a lot, so the size of LED lamp fluted body 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, fin at the groove thermal conductor, reduced the thermal resistance of groove thermal conductor, the heat of LED aluminium base is conducted to fin, fin and fin very soon by the groove thermal conductor, and carry out simultaneously radiation and heat loss through convection with surrounding air.Particularly be provided with ventilating opening at the interior ring center of annular groove thermal conductor, the heat of groove thermal conductor carries out the cross-ventilation heat radiation by this ventilating opening, thereby further reduces the temperature rise that the LED lamp produces.

On LED lamp fluted body radiator, be provided with the isolation pillar, the electronic devices and components of LED power pack inside and LED lamp fluted body radiator heat are isolated and are affected little thus, guarantee the electric 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, and be suitable for storehouse and factory building etc. dust is arranged, environment temperature is higher, high-altitude and on the LED light fixture that uses in the place of maintenance difficult.
