Description

Use the light-emitting device of LED

Technical field

The utility model relates to a kind of lighting, specifically is the light-emitting device of a kind of LED of use.

Background technology

Owing to compare with incandescent lamp, fluorescent lamp has power saving, brightness height, light near advantages such as natural daylights, so fluorescent lamp replace incandescent gradually has been undisputable fact.But the defective of fluorescent lamp still clearly: still than power consumption, brightness is still undesirable, and especially service life is short, easily broken and there is pollution etc. not shock-resistant, discarded back to environment.

In the last few years, occur a kind of stepless lamp again, and can correspondingly overcome some shortcoming of incandescent lamp and fluorescent lamp, but its price is too expensive, so the feasibility of generally applying is little.

In recent years, because the succeeding in developing of the LED of (sending out) white light, LED began to enter illuminating industry.The LED Chinese name is light emitting diode, and it belongs to cold light source.Compare with fluorescent lamp with incandescent lamp, it has, and power and energy saving, life-span are grown, are not generated heat, the shock-resistant advantage such as fragmentation that promptly is difficult for, and compare with fluorescent lamp, do not glimmer in addition, toggle speed is fast, the advantage of environmentally safe.At present, LED has begun to be used for flashlight, indicator lamp, exterior decoration lamp etc.But the LED light-emitting device of prior art will be widely used in book lamp (as desk lamp), emergency light, the lamp of camping, household lamp etc. and the nearer daily lighting of human body, also have following defective: the light source that a plurality of LED form is scattered point source of light, and the point source of light that each LED forms is all very dazzling again, stimulation to eyes is severe especially, so that cause injury to eyes, so, also can't be used for family and room lighting etc. and the nearer daily lighting of human body at present; Simultaneously, do not concentrate because the light source that its a plurality of LED form is scattered, so its optical efficiency and brightness are all undesirable.

The utility model content

The technical problems to be solved in the utility model is, a kind of original advantage that can give full play to LED is provided, can form soft light source, and optical efficiency and brightness are all very good, can be widely used in the light-emitting device of the use LED of the nearer daily lighting of family and room lighting etc. and human body.

The technical solution of the utility model is, a kind of light-emitting device with use LED of following structure is provided, the LED and the power supply that comprise at least one white light, it comprises that also the end plate and the two ends of the cylindrical shell of a transparent material, two blocks of insulating materials are separately fixed on two end plates and two one metal wires that are connected with power supply; The bipod of described at least one LED is connected on two one metal wires; The cylindrical shell of described transparent material refers to be respectively equipped with on the inside and outside wall cylindrical shell of the striped that the next door intersects or refers to adopt the cylindrical shell of the smooth wall that light diffusion resin makes.

After adopting above structure, the light-emitting device of the utility model use LED compared with prior art has following remarkable advantage and beneficial effect:

Utilize optical principle,, the dazzling dot light of original LED is become the soft light source that is evenly distributed, make light source no longer dazzling through the optical treatment of the utility model light-emitting device, both non-stimulated to eyes, there is not injury again.Thoroughly having solved in recent years this technical field tackles key problems many times and thirsts for solving, and a big technical barrier that is resolved not yet up to now, and optical efficiency and brightness all very good (optical efficiency and brightness all are the various electricity-saving lamps of fluorescent lamp＜comprise〉more than seven times.Because of fluorescent lamp is better than incandescent lamp, thus only compare with fluorescent lamp, down together), can be widely used in family and room lighting etc. and the nearer daily lighting of human body, as book lamp, emergency light, the lamp of camping, household lamp etc., have general widely promotional value.The utility model uses the light-emitting device of LED to keep and brought into play more fully original advantage of LED: compare power and energy saving (only be fluorescent lamp power consumption about 1/10th) with fluorescent lamp (comprising various electricity-saving lamps); Shock-resistant promptly be difficult for broken, long service life (be incandescent lamp and fluorescent lamp about 20 times); Because of it belongs to cold light source, do not generate heat (72 hours its temperature of continuity point still are room temperature); Environmental protection is that its discarded object does not have any pollution to environment; Do not glimmer; Toggle speed is fast; Light more approaches natural daylight etc.And compare with stepless lamp, its price then have only its 1/50th.

As improvement, two one metal wires are symmetrically distributed in the both sides in the end plate center of circle, make its distribution of light sources in transparent cylindrical shell more even.

As further improvement, LED can be many, and be connected in parallel on two one metal wires, and equate, like this along the axial distance each other of cylindrical shell, under the optical effect of cylindrical shell, many LED just form columnar light source, and light source is more evenly distributed in transparent cylindrical shell, make the light source of this light-emitting device softer, its optical efficiency is higher, and its brightness is stronger.

As further improving again, be provided with the reflector that its outer surface has reflectorized material at an end or two ends of cylindrical shell, make the optical efficiency of this light-emitting device higher, its brightness is stronger.
