Specific embodiment
It is the combined lamp based on fisheye light distribution structure of the invention shown in reference picture 1, including radiator 10, face ring
20th, lamp holder 30, LED light source, reflector 40 and lens 50, the lamp holder 30 are fixed on the afterbody of radiator 10 and are inserted for being arranged on
Seat, the radiator 10 has inner chamber and the inner chamber is for assembling the LED light source, reflector 40 and lens 50, the LED light source
Installed in the smooth surface of lens 50, the lens 50 are arranged on the light inlet of reflector 40, and the top port of reflector 40 is by described
Face ring 20 is connected with an eyeglass, wherein, LED light source selects COB light source.
The light sent by LED light source first passes around the refraction condensation of lens 50, and enter back into is carried out repeatedly in reflector 40
Reflection carries out uniform treatment, reduces halation and dazzle, finally projects eyeglass.
As shown in Figure 2 and Figure 3, lens 50 include lens cover 501 and the bullet 502 in lens cover 501, should
The top of bullet 502 offers the first groove 503, and the bottom surface of the first groove 503 is provided with the convex surface minutia of dense distribution, cone
The bottom of body 502 offers the second groove 504 to be used to assemble the LED light source.
A circle frosted layer 505 is provided with the bullet 502, the frosted layer 505 is located at the outside of the first groove 503, the
Light after one groove 503 is reflected carries out diffusing reflection in frosted layer 505.The cover of the lens 50 both sides are each provided with a pin 506,
Pin outside is provided with back-off 507, and the back-off 507 is used for the fixation of lens 50 and radiator 10.
Lens 50 mainly have two effects：One is designed by the shape and structure of lens 50, by the concentration light of COB light source
Dissipated to reflector 40 by the refraction of lens 50, solve COB light source light and concentrate, light fixture is easily produced center haloing, light
The not soft problem of line；Two is that diffusion is diffused into again for the light that is reflected lens 50 by the salient point of the outer surface of lens 50
Periphery, so as to further eliminate COB light source LED lamp center haloing, makes plane of illumination light intensity more uniform, eliminates dazzle；Through inspection
Survey the transmissivity of lens 50 and reach 94%, distribution curve flux luminance transition is smoothed, and is formed without mutation and blackening.
As shown in figure 4, the inner surface setting of the reflector 40 has multiple evenly distributed faceted pebbles 401, each faceted pebble 401
The fisheye reflecting layer that the minute asperities point of dense distribution is constituted is provided with, using the physical reflection principle of light, by COB light source through saturating
Light that mirror 50 is refracted to reflector 40 certain point goes out reflector 40 with multiple different angle reflections, (because being projected according to light
To the incident angle of lampshade, light is not had can be reflexed on lens 50.), due to depositing for numerous sags and crests or triangle fold
, good high reflection and diffusing reflection are formed, can not only expand shadow surface, and illumination drop can be formed in irradiation area and put down
Sliding uniform irradiation.Technique is beaten and improves reflecting effect on conventional reflector surface, after testing light utilization can cross to
97%, and irradiation area light can be made soft, reduce the harm of dazzle.
It is provided with the radiator 10 by some fins and circulation groove, fin and circulation groove longitudinal arrangement alternate with each other are constituted
Section be curvilinear radiating inwall, be provided with some boss 101, boss 101 between the inwall and outer wall in the body of radiator 10
Between be provided with air-vent 102, form air circulation convection heat dissipation structure, shape between the air-vent 102 and radiating inwall of radiator
Into internal air cycle heat radiation.
It is provided with the radiator 10 by some fins and circulation groove, the helical form of fin and the transversely arranged composition of circulation groove
Radiating inwall, some boss 101 are provided between the inwall and outer wall in the body of radiator 10, it is provided with air-vent between boss 101
102, air circulation convection heat dissipation structure is formed between the air-vent 102 and radiating inwall of radiator, the air inside formation is followed
Ring radiates.
, using the aluminium alloy (this technology is cooperated with supplier) containing rare earth metal, rare earth is in aluminium alloy for the material of radiator 10
In can form thermohardening complicated ingredient compound high, in net distribution in crystal boundary or interdendritic, refined tissue, effectively
Matrix deformation and crystal boundary movement are hindered, so as to significantly improve the high-temperature behavior of alloy, and heat dispersion is greatly improved, than general
Logical overall raising 9.59%.
As shown in figure 5, by the data of technical performance table, can analyze：Know from isocandela curve, without lens, without anti-
Its plane of illumination of light cup Down lamp is unfettered, and without light ability is matched somebody with somebody, illumination range is uncontrollable；There is the plane of illumination of reflector Down lamp without lens
It is controllable, but substantially center luminosity is strong, and peripheral light is weak, illuminance is uneven；Fisheye reflector adds fisheye lens drum lamp illumination
Range of light is uniform.
By the data of technical performance table above, can analyze：For LED PAR lamps, (and LED down lamp, LED are penetrated
Lamp) be for, it is radiated by radiator, and these places of lamp holder, lampshade are conducted heat.
Analyzed from test report, when just starting two sample heat sink inner surfaces close to the local temperature of lamp bead be close
, after a period of time, good heat conductivity can go out internal heat produced, and the inside of lamp does not accumulate heat, at this moment outer surface
Temperature it is almost similar with inner surface.The product of heat conductivility difference, the transmission of heat is no so good, and the temperature of outer surface does not have
Have so high (it is envisioned that once, the hull-skin temperature of down jackets is almost much the same with the low temperature of outside with it, because dissipating
Not heat, heat all stays in the inside), heat is almost accumulated in lamp body the inside, such lamp holder, lampshade temperature it is high, radiator
The temperature of outside is low on the contrary.
That is lamp holder, lampshade temperature it is lower, heat dispersion is better, the temperature radiating higher of radiator outer surface
Speed is faster.Therefore, from the data of examining report, using the radiator of the radiator than common material of rare earth aluminum alloy material
Performance integrally improves 9.59%.
" the combined type optical system " that fisheye lens constitute is added by fisheye reflector, is light trade optical design techniques
Another bright spot, thus the LED lamp of innovation achievement development not only efficiently solve current similar illuminance of lamp uniformity it is low,
The problems such as dazzle value is high and beam angle is not accurate, and the light on conventional reflector surface can be overcome to reflect less, space is respectively to unrestrained
The big defect of reflection, is conducive to the optical component for lowering key to design and produce difficulty and improves overall lamp in more important actual production
Has the accurate reliability of assembling.
" fisheye reflector adds fisheye lens ", as combined type optical system, is that brand-new design concept is provided in industry
And technical experience, wherein having merged multinomial optical design techniques and part production technology and combination technique, therefore can be considered light fixture
The integrated application of optical design techniques, thus itself be also a new technology.
Preferred embodiments of the invention are the foregoing is only, the present invention is not limited to above-mentioned implementation method, as long as with
Essentially identical means realize that the technical scheme of the object of the invention is belonged within protection scope of the present invention.
