Detailed description of the invention
Fig. 1 shows the general layout of design to 3, and the form in below then determines crucial element, and namely bullets is equivalent to the Reference numeral in figure.
Lower illuminator is mounted with together by the screw 11/12 between spring clip 7 and lens-mount 2.Two pads 6 between base 4 or 5 and radiator 3 create the air gap 17 of an opening, for direct, the free-pouring air of energy in environment are transported to the whole surface of radiator 3, comprise bottom hot LED, cool to utilize effective convection current.The outer rim of the air gap creates different hacures 17.The ventilating opening 8 of several equally distributed 10mm diameter strengthens air-flow, and typically, the quantity of this ventilating opening 8 is 6 ~ 8, and this ventilating opening 8 is positioned at around lens-mount.
The size of two bases achieves economic assembling.
Be that the design 2 of the base 4 of 80 millimeters is applicable to the application with diameter, and install for surface; This base has the fastener hole 9 installed for surface, can enter two complete relative ventilating openings 8.
This base is designed to the general installing hole 18 of cooperation 55 millimeters, and is arranged in hole 18 with two spring clips 7.
Designing with the diameter base that is 110 millimeters is application after repacking; In prebored hole 15, self-tapping screw 14 fixing spring is utilized to press from both sides 7.The quantity of prebored hole is enough to enable the spring clip of installation be securely fixed in existing construction opening by lower illuminator, and the diameter of this construction opening is 50 to 100 millimeters.
Spring clip 7 must bend, and makes install by hasp tightly in construction opening.
The pad of screw assembly 6 is made up of aluminium alloy, with the centre bore of 3.5 mm dias.
The pad of screw assembly 6 also can be made up of stainless steel or brass, with the centre bore of a M3-screw thread.Harder metal makes minor thread have enough intensity.
Radiator 3 has the pilot hole of two 3.5 millimeters, and several (typically being 6-8) ventilating opening (diameter is 10 millimeters), promotes that air-flow carries out convection current effectively.
A LED array is positioned at its bottom centre, and fixes with thermal bonding tape or adhesive.It is covered by silicone lens 13, and lens-mount 2 utilizes assembling screw 11/12 to fix this silicone lens 13.This silicone lens protection array, provides light to guide, and by contacting with LED framework, guarantees the surface cool of array.
Commercially can buy, qualified LED power supply be installed in ceiling recess or near, and with to insulate and the electric wire marked is connected, guide this electric wire 20 by a hole in the base.All elements are all made up of stainless material, and all screws are all stainless.
Due to practicality, the surface of radiator is generally color steel white.
Do not need other surface treatment.
The lower illuminator of the efficient and cost-effective in Fig. 1 ~ 2 take hacures as feature.It obtains by the radiator concept of uniqueness the best cooling effect that LED 1 may reach, this LED as individual unit, group or array to combine with silicone lens for the protection of, cool and efficient light regime.The application distortion of floodlight and some light is possible.
Two disks made by aluminium or substituting suitable metal are main elements:
Base 5, this base typically is 2 millimeters thick, and diameter is 70 millimeters, is adapted to the installing hole of 60 millimeters, and is equipped with one for fixing spring clip 7.
Radiator 3, this radiator typically is 2-3 millimeters thick, and diameter is 80-120 millimeter.
The size of installing hole is only needed to determine by the installation of PS.
At least large than opening 10 millimeters of the diameter of base, and the diameter of radiator large 10 millimeters at least again, to set up clean hacures.
According to selected lower illuminator allow the needs of operating temperature, this radiator has a minimum diameter.Such as, the radiator that diameter is 120 millimeters can provide sufficient cooling for the LED of 20W exports.
Diameter is 12 millimeters, and base 5 and radiator 3 couple together by the metallic gasket 6 of long 8 millimeters, and is that free-pouring environment cools air creates an open the air gap.
Partition also by transfer of heat to base, this base contributes to cooling effect.The whole surface of radiator 3 directly contacts with cooling-air, especially the hottest part, and this radiator is in the bottom of LED.This make use of maximum possible temperature difference drive environment cooling-air.
The visible face of radiator is only had just to need to carry out surface treatment.
For a person skilled in the art, after reading above-mentioned explanation, various changes and modifications undoubtedly will be apparent.Therefore, appending claims should regard the whole change and correction of containing true intention of the present utility model and scope as.In Claims scope, the scope of any and all equivalences and content, all should think and still belong in intention of the present utility model and scope.
