Abstract
A kind of LED Down lamp can, can thoroughly solve Down lamp blackspot problem, formed by Down lamp annular cover, lens, aluminium base, reflexed light ring, between Down lamp annular cover, lens, aluminium base, reflexed light ring, it is all gap-free sealed connection, it is characterized by: Down lamp lamp holder the inside is seal cavity, and through hole does not dispel the heat; Lens are placed on cover the inside, and with smooth contact of Down lamp annular cover inner edge frame; Aluminium base is placed on the reflexed light ring inner plane surface that scribbles silica gel, and is fixedly connected with radiation aluminium body; Above aluminium base, weld LED lamp pearl and wire, wire is derived outside through aluminium base, threading hole; On aluminium base, inject PUR and cover threading hole, and cover on 2 wire insulation bodies.This LED Down lamp is produced simple, and cost is low, and can be good at ensureing light transmission.
Description
Technical field
The present invention relates to a kind of LED Down lamp can.
Background technology
Since entering 21 century, domestic LED lighting engineering ripe gradually, compared with conventional light source, the advantage such as LED has energy-conserving and environment-protective, and the life-span is long, sound construction, is widely used gradually.But the design of Sealing Structure of prior art is not in place, a lot of LED Down lamp radiation aluminium bodies and aluminium base have threading hole on the market, but are not sealed, and cause in use having dust, water smoke and mosquito etc. and enter lampshade, form blackspot.Blackspot problem can weaken illuminating effect, also can shorten the life-span of lamp and affect attractive in appearance.This utility model patent can thoroughly solve the blackspot problem on frosted lens.
Summary of the invention
A kind of LED Down lamp can, formed by Down lamp annular cover, lens, aluminium base, reflexed light ring, between Down lamp annular cover, lens, aluminium base, reflexed light ring, be all gap-free sealed connection, it is characterized by: Down lamp lamp holder the inside is seal cavity, and through hole does not dispel the heat; Lens are placed on cover the inside, and with smooth contact of Down lamp annular cover inner edge frame; Aluminium base is placed on the reflexed light ring inner plane surface that scribbles silica gel, and is fixedly connected with radiation aluminium body; Above aluminium base, weld LED lamp pearl and wire, wire is derived outside through aluminium base threading hole; On aluminium base, inject PUR and cover threading hole, and cover on 2 wire insulation bodies.
What lens adopted is frosted lens or transparent glasses lens.
PUR covers threading hole and through threading hole, covers the fraction of the other one side of aluminium base after making PUR by aluminium base again.
Between aluminium base and reflexed light ring, there is heat conductive silica gel, connect two wires, derive from the threading hole of aluminium base, reflexed light ring, radiation aluminium body successively respectively, finally the aluminium base connecting, reflexed light ring and radiation aluminium body, the Down lamp ring surface that lid is provided with frosted lens inside covers, with the bending clamping of the connecting card reflexed light ring of Down lamp annular cover, a LED Down lamp lamp holder thereby assembling is over.
Fixed form, silica gel or screw are fixed
Owing to often will swinging when mounted power line, connect after driving, the wire of drawing from aluminium base has certain length, so the PUR amplitude of fluctuation after injecting glue on lamp holder is little, also may cause PUR to come off on aluminium base, in order to address this problem, PUR need to cover threading hole, and through threading hole, and the other one side sub-fraction that can also cover aluminium base after making PUR by aluminium base; The cooling clamping afterwards of PUR is fixed on the threading hole with the aluminium base of wire, has not only solved LED Down lamp sealing problem, also solves the problem that causes PUR to come off while installing and using LED Down lamp.Shell has the spring assembly that fixing ceiling is installed.
This LED Down lamp can, makes the space above LED lens completely sealed, reaches good sealing effectiveness, and dust, water smoke and mosquito etc. just do not enter lampshade, have stopped blackspot problem.The problems such as " weaken illuminating effect, shorten the life-span of lamp and affect attractive in appearance " that blackspot problem causes are also just resolved.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details
Embodiment 1
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of LED Down lamp can, being made up of Down lamp annular cover (1), lens (5), aluminium base (7), reflexed light ring (3), is all gap-free sealed connection between Down lamp annular cover (1), lens (5), aluminium base (7), reflexed light ring (3).Down lamp the inside is seal cavity, and through hole does not dispel the heat; Frosted lens (5) is placed on Down lamp annular cover (1) the inside, with smooth contact of the Down lamp annular interior frame of cover (1); Aluminium base (7) is placed on reflexed light ring (3) the inner plane surface that scribbles silica gel, and be connected with radiation aluminium body (4), aluminium base (7) welds LED lamp pearl (6) above, derive two power leads (8), above inject PUR (9) and cover threading hole (10) at aluminium base (7), and covering on 2 wires (8) insulator.
Embodiment 2
A kind of LED Down lamp can, Down lamp the inside is seal cavity, through hole does not dispel the heat; Frosted lens is placed on Down lamp annular cover the inside, cover is smooth contacts with Down lamp annular, aluminium base is placed on the reflexed light ring inner surface that scribbles silica gel, and be connected with heat sink, above aluminium base, weld LED lamp pearl, connect two power lines, reusable heat melten gel notes glue on the threading hole surface of welding two power lines, make PUR all cover threading hole, with all remaining louvres of PUR sealing.
The above is only preferred embodiment of the present utility model, the structure that every similar embodiment is similar to therewith, and this technology goes for the LED Down lamp of different wattages, all should be covered by the protection domain of the utility model patent.
