Abstract
The utility model discloses a large size light emitting diode (LED) tube light, which relates to the field of LED lights, and comprises a round aluminum circuit board (1), wherein a plurality of LED lamp beads (2) are welded on the front surface of the round aluminum circuit board (1) to form a unit, a plurality of units are connected with a constant current drive power (8) through a power wire (7), the power wire (7) is lead out from a thread hole (9), the back surface of the round aluminum circuit board (1) is connected with a lamp shell (3) through screws (4), and a lamp and a mounting buckle (5) are fixedly arranged through a shell edge (6). The large size LED tube light is characterized in that the dimension scale between the diameter length and the height of the lamp shell (3) is 1:1. The large size LED tube light is soft in light and also high in lighting effect simultaneously.
Description
Technical field
The utility model belongs to lighting field, particularly LED light fixture.
Background technology
LED lamp is a kind of luminescent device that electric energy can be directly changed into luminous energy output, is a kind of cold light source without filament.Because LED light source has the energy of saving, the life-span is long, volume is little, safe and reliable, environment friendly and pollution-free, multipurpose, is easy to the advantages such as controls, has replaced gradually conventional light source, the at present application of LED Down lamp also very generally.Because the power ratio of large scale LED Down lamp is larger, most Down lamps or be exactly that light efficiency is low, or be exactly that light is dazzling, undesirable in room lighting effect.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and a kind of large scale LED Down lamp is provided, and its light efficiency is high, and light is soft, is applicable to room lighting; The technical solution adopted in the utility model is:
A kind of large scale LED Down lamp, comprise: the circular aluminum base circuit board multiple LED lamp pearls of positive welding also form a unit, connect with power line and power line is drawn from through wires hole with constant-current driving power supply by multiple unit, the back side is connected by screw with lamp outer casing, and light fixture entirety is tipped row fixed installation in by shell edge and installing card; The height dimension ratio of the diameter length of described lamp outer casing and lamp outer casing is 1:1.
As further improvement of the utility model scheme, the LED lamp pearl quantity on described circular aluminum base circuit board is 15-30, preferably 21.
As further improvement of the utility model scheme, described unit number is 5-10, preferably 5-8; More preferably 6.
As further improvement of the utility model scheme, described lamp outer casing material is iron-clad or Al alloy shell.
As further improvement of the utility model scheme, described lamp outer casing diameter and lamp outer casing height dimension are 15-30 centimetre, preferably 18-25 centimetre, more preferably 20 centimetres.
As further improvement of the utility model scheme, the spacing distance between described circular aluminum base circuit board is for being greater than double diameter 2-5 centimetre, preferably 3-4 centimetre, more preferably 3.5 centimetres.
As further improvement of the utility model scheme, described LED lamp pearl is the one in LED paster packaged lamp pearl, LED COB packaged light source, the high-power packaged lamp pearl of LED.
The utility model major technique effect:
1, in such scheme, the height dimension ratio of the diameter length of lamp outer casing and lamp outer casing is 1:1, makes the light can be soft by rational dimension scale, and light efficiency is high again simultaneously.
2, the corresponding distance in interval between circular aluminum base circuit board, can reduce the cost of circuit board, reaches best radiating effect simultaneously, makes, in the temperature control 40-80 degree of circuit board, to meet the radiating requirements of relatively high power Down lamp.
3, lamp outer casing and circuit board link into an integrated entity, and serve as radiator, the better effects if of heat radiation.
Brief description of the drawings:
Accompanying drawing 1 is the utility model structural plan figure;
Accompanying drawing 2 is the utility model circuit board wiring diagram;
1 circular aluminum base circuit board, 2LED lamp pearl, 3 lamp outer casings, 4 screws, 5 install buckle, 6 shell edges, 7 power lines, 8 constant-current driving power supplies, 9 through wires holes.
Detailed description of the invention
Referring to accompanying drawing 1, accompanying drawing 2, a kind of large scale LED Down lamp, comprise: circular aluminum base circuit board 1 positive welding 20 LED lamp pearls 2 also form a unit, connect and power line 7 is drawn from through wires hole 9 with constant-current driving power supply 8 use power lines (7) by 5 unit, the back side is connected by screw 4 with lamp outer casing 3, and light fixture entirety is fixed installation by shell edge 6 and installation buckle 5; The height dimension ratio of the diameter length of described lamp outer casing 3 and lamp outer casing is 1:1.Described lamp outer casing 3 diameters and lamp outer casing height dimension are 20 centimetres, and this ratio makes light soft.Described lamp outer casing 3 materials are iron-clad or Al alloy shell; Spacing distance between described circular aluminum base circuit board 1, for being greater than at least 2 centimetres of double diameter, is convenient to heat radiation.
Obviously, the utility model is not limited to above preferred embodiment, also can be in the spirit of the utility model claim and description restriction, carry out conversion and the improvement of various ways, can solve same technical problem, and obtain the technique effect of expection, therefore do not repeat.Those of ordinary skill in the art can be from the disclosed content of the utility model directly or all schemes of associating, as long as within the spirit limiting in the utility model claim, also belong to protection domain of the present utility model.
