Description
Technical field
The utility model relates to a kind of LED lamp structure of full period-luminosity type, particularly a kind of LED lamp structure that reaches full ambient light illumination.
Background technology
Along with scientific and technological industry is constantly progressive, traditional light fixture (like bulb) is little by little by light emitting diode (Light Emitting Diode; LED) replace because light emitting diode has that volume is little, long service life, driving voltage are low, fast or the like the characteristics of reaction speed, its easily with life arround all types of products combine, and as the purposes of illumination or demonstration.Since light emitting diode luminous be folk prescription to ejaculation, effect is pretty good for the unidirectional illuminator of flashlight, searchlight, desk lamp or the like.But, still have many technical problems to overcome if be employed on the light fixture that is designed to radial luminous (full ambient light illumination).
In order to make led lamp that full ambient light illumination can be provided, several kinds of technical schemes have been proposed at present on the market, it is described below:
At first, see also the cross-sectional view of Fig. 1 for existing a kind of led lamp.As shown in the figure, led lamp 100 is a bulb type light fixture, and it comprises a lamp socket 11, a light emitting diode 13 and a lampshade 15.
Wherein, lamp socket 11 comprises a lamp holder 111 and a cooling base 113.Light emitting diode 13 is rearranged by several light emitting diodes, and is arranged on the top, central plane place of the cooling base 113 of lamp socket 11.Lampshade 15 is a dome-type lampshade, and coating light emitting diode 13, moreover the inwall of lampshade 15 can be coated with phosphor powder 151 along the peripheral planar setting of the cooling base 113 of lamp socket 11 for it.。
Through the setting of phosphor powder 151, the light that light emitting diode 13 is sent will excite phosphor powder 151 luminous, and part light carries out scattering in lampshade 15 the insides, cause the purpose that reaches full period-luminosity to cause diffusion effect.
As see also Fig. 2 for having the cross-sectional view of another kind of led lamp now.As shown in the figure, led lamp 200 is similarly a bulb type light fixture, and it includes a lamp socket 11, a light emitting diode 13 and a lampshade 15, and the uncoated phosphor powder 151 of the inwall of lampshade 15.
Again, further consult Fig. 3, led lamp 200 still comprises a leaded light post 27, and leaded light post 27 is the column structure of a refractive index n 1, and its both ends of the surface have a reflecting surface 271 and a holding part 273 respectively.Wherein, the reflecting surface 271 of end face presents the cone of guide light beam 27 body indents, and the holding part 273 of bottom surface presents the groove of guide light beam 27 body indents to provide the accommodation space coating this light emitting diode 13.
When light emitting diode 13 by driven for emitting lights, the light that light emitting diode 13 is sent up gets into leaded light post 27 via holding part 273, to get into leaded light post 27 inside of refractive index n 1 from the surrounding medium (air) of refractive index n 2.Moreover because both refractive indexes of leaded light post 27 and surrounding medium are different, so that light can be worn in leaded light post 27 and penetrates and reflect.And, part light can reflecting surface 271 places reflections and toward light fixture 200 both sides or below direction advance, and then wear again and be incident upon among the surrounding medium, make front, side, the below of led lamp 200 that the light ejaculation all arranged, and reach the purpose of full period-luminosity.
Though above-mentioned two kinds of technical schemes can reach the effect of full ambient light illumination, right, use leaded light post 27 or a large amount of phosphor powders 151 will make the cost of manufacture of light fixture relatively improve many.
At this, the utility model will provide a kind of LED lamp structure of innovation, utilize simple structure can realize the effect of full ambient light illumination, and also can reach the lower purpose of cost of manufacture.
