Description
Technical field
The present invention relates to a kind of lighting apparatus, particularly the LED shot-light of imitative incandescent lamp light.
Background technology
Along with social development of science and technology and progress, living standard constantly improves per capita, and also more and more higher to irradiation " light " requirement of illumination or appointment irradiating object, former incandescent shot-light shines on the object, and object is keeping as seeing in the sunlight; Light is comfortable, but relatively power consumption of incandescent shot-light, irradiated environment temperature rises easily, service life is short, therefore invented energy-conservation by the clever wisdom of people, the LED shot-light of environmental protection, but LED is spot light, must carry out optically focused for reaching reasonable radiation response, and traditional optically focused is to carry out optically focused by concave mirror, yet this concave mirror minute surface is contaminated or corrosion easily, influence reflecting effect, for substituting concave mirror, some collector lenses have also appearred on the market, led light source can obtain reasonable focus irradiation effect through behind the collector lens, the reflecting surface of these collector lenses mostly is smooth parabola reflecting surface or other curve reflectings surface, though parabola reflecting surface or other curve reflectings surface can be realized extraordinary optically focused direct projection effect, but this smooth surface optically focused direct projection effect is very dazzling dazzling in actual applications, can not reach the effect of mixed light, so illuminating effect is bad.
Summary of the invention
The objective of the invention is the same LED shot-light that reaches the imitative incandescent lamp light of the soft effect of light of light that a kind of good illumination effect is provided in order to solve above-mentioned the deficiencies in the prior art and penetrates with incandescent lamp.
To achieve these goals, the LED shot-light of the imitative incandescent lamp light that the present invention is designed, comprise lamp holder, the plastic cement base, power supply, radiator, Led light source and protecgulum, described power supply is fixed in the plastic cement base, plastic cement base one end is fixedlyed connected with lamp holder, the other end is connected with radiator, Led light source plane is fixed in the radiator, front end with respect to the Led light source in radiator also is provided with the check lens, described check lens comprise first diffusingsurface, internal reflection surface, second diffusingsurface and the spill focal point that is constituted by first diffusingsurface, described internal reflection surface is made up of one and above optically focused salient point and the reflecting curved surface of arranging by rule, and is provided with optical thin film layer outside the optically focused salient point of internal reflection surface.
The light diffusion principle: when light is mapped to lens, adopt recessed principle with the light gathered light on the spill focal point; Spread towards periphery by first diffusingsurface this moment again, at this moment the light that diffuses out is mapped on the optically focused salient point, because the outer surface of optically focused salient point has optical thin film layer again, because when optical thin film layer forms outside the optically focused salient point, optical thin film layer has also just become concave surface, making has spotlight effect, poly-light can gather diffusing again mutually, thereby improved the effect of luminous efficiency and reflection, and finally penetrate from second diffusingsurface, light is through such reflection repeatedly, focus on, thereby make the light that shoots out reach that the light that penetrates with incandescent lamp is about the same to have a softness, comfortable effect.
In order to make light to diffusion all around, improve diffusion effect, described first diffusingsurface is convexity arc surface.
For the angle of illumination, described second diffusingsurface is the male type cambered surface.
In order to reduce product temperature, make the light efficiency of LED lamp more stable, be provided with the wind wheel type radiating ribs at radiator, be provided with the air vent that cooperates and form passage with the wind wheel type radiating ribs at protecgulum.Therefore realize when radiator and protecgulum are fastened, air vent and wind wheel type radiating ribs formation passage, owing to this passage like chimney, cold air enters from passage, the all heats in radiator surface are taken away, thereby reduced product temperature, make the light efficiency of LED lamp more stable.
In order to realize irreflexive principle, thereby realize lighting effect, described reflecting curved surface is to meet the curved surface formula: Z=0.34 (X
2+ Y
2)-3 are wherein: 0≤Z≤5; Described optically focused salient point is to meet curved surface formula: 3*Y
2+ 4 (X
2+ Z
2)=60 are wherein:
First diffusingsurface is to meet the curved surface formula:
Wherein: 0≤| X|≤5,0≤| Y|≤5; Second diffusingsurface is to meet the curved surface formula: Z=0.1 (X
2+ Y
2) wherein: 0≤Z≤3.At this, X, Y, Z are 3-D walls and floors, and after the formula of foregoing description was provided, the curved surface that this formula is embodied in three-dimensional system of coordinate was that industry those of ordinary skill can be realized and obtain, so be not described in detail at this.
The LED shot-light of the imitative incandescent lamp light that the present invention obtains, when light is mapped to lens, adopt recessed principle with the light gathered light on the spill focal point; Spread towards periphery by first diffusingsurface this moment again, at this moment the light that diffuses out is mapped on the optically focused salient point, because the outer surface of optically focused salient point has optical thin film layer again, because when optical thin film layer forms outside the optically focused salient point, optical thin film layer has also just become concave surface, making has spotlight effect, poly-light can gather diffusing again mutually, thereby improved the effect of luminous efficiency and reflection, and finally penetrate from second diffusingsurface, light is through such reflection repeatedly, focus on, and make the light that shoots out reach good radiation response, and the same soft with the light light of incandescent lamp ejaculation, comfortable.
