Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of improvement mechanism of LED spotlight, it comprises radiator 1, reflector 2, eyeglass 3 and protecgulum 4, described radiator 1 front end offers the installing zone 11 caved inward, the center of installing zone 11 is installed with LED light source, it is characterized in that: described LED light source surface coverage has light-guiding pillar 5, light-guiding pillar 5 outer rim is provided with some contiguous blocks 6, arranging circular through holes 21 bottom described reflector 2 can by being pressed on contiguous block 6, reflector 2 is pushed by protecgulum 4 and being spirally connected of radiator 1, light-guiding pillar 5 is fixed on LED light source surface, described light-guiding pillar 5 main body extends in reflector 2 through through hole 21.
Described light-guiding pillar 5 entirety has transparent glass or acrylic material to make, overall in round table-like.
Described light-guiding pillar 5 comprises base portion 51 and top cap portion 52, and base portion 51, in up-small and down-big circular cone shape, pushes up the circular cone shape that cap portion 52 is big up and small down.
Described light-guiding pillar 5 inside offers up-small and down-big conical bore 53, and the bottom of conical bore 53 is provided with circular arc projection 54.
Described LED light source is COB area light source 7.
Described contiguous block 6 is provided with four pieces, is distributed in bottom light-guiding pillar 5 in center of circle array.
In described contiguous block 6, top end face is circular arc inner concavity, is pressed on the outer rim of the circular chip 71 of COB light source 7.
In described contiguous block 6, top is also provided with chuck 61, chuck holding on the base plate 72 of COB area light source 7, force COB area light source 7 closely and radiator 1 fit, ensure its capacity of heat transmission.
Operation principle: in the utility model is solve conventional lamp complex structure, assembling trouble, and production efficiency is low, there is light dazzling after luminous intensity distribution, have dazzle and uneven illumination even and there is the defects such as hot spot, propose a kind of brand-new luminous intensity distribution form and fitting structure.
In this case, have employed light-guiding pillar luminous intensity distribution to replace traditional lens luminous intensity distribution form, because light-guiding pillar volume is large, highly long, so when the light source sent by LED light source enters into after in light-guiding pillar, the refraction that needs carry out repeatedly in light-guiding pillar or reflection, add the cylinder of light-guiding pillar in middle little, the cross-sectional configuration that two ends are large, it can play the effect to light layering refraction, make light not single only from the bottom reflection of reflector, but can all participate in reflective radiation from all inwalls of whole reflector.Thus play the effect of whole reflector inwall luminescence, with conventional lamp only from compared with the effect of reflector bottom-emission, the light that this structure light fixture is equipped with out is more even, soft, promotes the surface of emission of light source, increases the range of exposures of light fixture.
Further, for enhancing productivity in this case, reflector is utilized directly to withhold bottom it light-guiding pillar, and fit tightly with LED light source, the pressure produced when utilizing protecgulum and radiator to install promotes reflector and extrudes light-guiding pillar, thus light-guiding pillar and LED light source are fixed effect on a heat sink by realization.Compared with the structure adopting gland structure fixed lens and LED light source with conventional art, in this case, simplify gland structure, eliminated the installation fixed work order of gland and radiator, while meeting instructions for use, reduced production cost, improve operating efficiency.Through calculating, the structure production cost in this case can reduce by more than 30%, therefore can extensively promote the use of, to promote the market competitiveness of producer.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; as the connected mode of light-guiding pillar and reflector, the structure etc. of light-guiding pillar, these changes and improvements all fall within the scope of claimed the utility model.
