Description
Technical field
The utility model relates to a kind of camphane modulated structure, especially refer to a kind of reflection type light-emitting diode camphane modulated structure, this camphane modulated structure is the madial wall that the supporter of a plurality of inclinations equidistantly is solidly connected to an annular framework, make the light emitting diode on the supporter penetrate light towards above water direction, simultaneously a plurality of reflective knee-pieces are solidly connected on the madial wall of this annular framework position corresponding to light emitting diode, to utilize the respectively arc-shaped curved surface of this reflective knee-piece, the light that light emitting diode produced of correspondence is reflected below and the close position that diffuses to this camphane modulated structure equably, therefore can effectively enlarge the illumination zone of this camphane modulated structure, avoid producing ghost image and bright because of illumination zone is too narrow, the problem of dark space.
Background technology
In recent years; progress along with science and technology; the demand of the energy also increases; the past people are for night or room lighting; usually can adopt fluorescent lamp; yet, because the service life of fluorescent lamp is very short, only about 1; 000 hour; and existing fluorescent lamp is with set within it vacuum or be full of in the space of inert gas of a tungsten filament, and with electric current by this tungsten filament, make this tungsten filament be heated to white heat; and then emit beam; therefore, fluorescent lamp only can be converted into luminous energy with 10 of received electric energy, but will be converted into useless heat energy up to 90 percent electric energy; and be lost in the air; cause the meaningless consume of electric energy, not only waste energy in a large number, more natural environment is caused white elephant.
Be the shortcoming (as: service life is short, photoelectric conversion rate is low) that solves above-mentioned fluorescent lamp, the light emitting diode that has environmental protection and energy-conservation demand concurrently just arises at the historic moment thereupon; Under the equal illumination condition, 40 times of the high life Dagri light modulation of light emitting diode, be about 40,000 hour, its power consumption but only is 1/10th of fluorescent lamp, and noxious material such as not mercurous in the light emitting diode, the light that it projected can not produce heat or radiation (in the light source light spectrum that light emitting diode produced yet, do not contain ultraviolet ray or infrared ray), the manufacturing technology that adds light emitting diode is ripe gradually, its cost price also constantly descends, and makes light emitting diode replace fluorescent lamp gradually, becomes the main light source in the current lighting.
From the above because light emitting diode has become main light source in the current lighting, industry then develop gradually various with light emitting diode as the main lighting lamp structure of light source, now cooperate Fig. 1, at existing led lamp, explain as follows:
See also known light emitting diode camphane modulated structure 10 shown in Figure 1, this camphane modulated structure 10 comprises a housing 11 and a plurality of light emitting diode 12, one end of described light emitting diode 12 equidistantly is solidly connected on the inside bottom surface of this housing 11 respectively, it is held in addition is oriented to towards the direction away from this housing 11, when producing light to receive external power source respectively when described light emitting diode 12, described light can penetrate towards the direction away from this housing 11, and then illuminates the below and the close position of this camphane modulated structure 10.
Yet this camphane modulated structure 10 still has shortcoming; See also shown in Figure 1 again, the light that this camphane modulated structure 10 utilizes a plurality of light emitting diodes 12 to be produced, direct irradiation its below and close position, because the directionality of the light that light emitting diode 12 is produced is extremely strong, its scope that can throw light on is very narrow again, therefore produces as shown in Figure 1 dark space 13 and clear zone 14 easily in illumination zone; Though, the dealer can be via holding in addition of described light emitting diode 12 optical lens 15 being set, the light that described light emitting diode 12 is produced scatters to position far away, reaching the effect of the scope of dwindling dark space 13, but and can't thoroughly eliminate the generation of dark space 13; In addition, the dealer is arranged by increasing the quantity of light emitting diode 12 in this camphane modulated structure 10, or described light emitting diode 12 more is closely arranged in this camphane modulated structure 10, to reach the effect that enlarges illumination zone, yet, the quantity of light emitting diode 12 is many more, the heat that it the produced height of also can healing, in case the heat that light emitting diode 12 is produced in this camphane modulated structure 10 can't scatter and disappear smoothly, to cause the temperature of this camphane modulated structure 10 high, under the behaviour in service of long-time continuous high temperature, will make this camphane modulated structure 10 produce serious material ageing and light decay phenomenon, and seriously shorten its service life; Moreover, increase the quantity of light emitting diode 12 in this camphane modulated structure 10, not only can't thoroughly solve it and be easy to generate problem bright, the dark space, the light direct irradiation that can be produced because of described light emitting diode 12 more, and produce the mottled multiple ghost image straggly of light and shade in the field of illumination and dazzle light, cause personnel movable under these camphane modulated structure 10 lighting environments can't clearly look thing, what is more, personnel's eyesight will be subjected to ghost image and dazzle the damage of light, and produce to degenerate, this result will be all the dealer and user institute is happy sees.
Because aforesaid light emitting diode 12 is installed in the camphane modulated structure 10, to produce light and to illuminate the below of this camphane modulated structure 10 and during close position, have and aforementionedly be easy to generate ghost image, dazzle light and shortcoming bright, the dark space, therefore, how to design a kind of reflection type light-emitting diode camphane modulated structure of innovation, decapacitation provides outside the large-scale illumination, still can produce uniform lighting effects, effectively avoid ghost image and problem bright, that the dark space produces, promptly become the important topic that the utility model is inquired in this desire.
In view of this, for improving the shortcoming of known camphane modulated structure, the designer is through the permanent research and experiment of making great efforts, and development and Design goes out a kind of reflection type light-emitting diode camphane modulated structure of the present utility model finally.
