Technical scheme of the present invention is: a kind of LEDG4 light fixture, comprises luminaire body, is arranged on driving power and LED lamp group in luminaire body; Described LED lamp group comprises substrate and is arranged on the LED chip on substrate; On described luminaire body, be nested with a radiator, described radiator is provided with some outward extending lobes portion; The inner face of described lobe portion is the reflective surface of a relatively described LED lamp group.By abandon LEDG4 light fixture traditional enclose enclosed construction, and adopt open Mechanical Builds, by the multiple reflections between reflective surface with by the transmission in gap between lobe portion, thereby produce colorful gorgeous lighting effect.In addition day, by the lobe portion of light fixture, effectively improve the radiating effect of LED Candlepower lamps and lanterns, improved the service life of LED light fixture.
In order further to improve the radiating effect of LEDG4 light fixture, described lobe portion is circumferential interval and arranges, and in lobe portion, is provided with the heat dissipation channel of perforation.By the gap between the heat dissipation channel in lobe portion and lobe portion, the heat generation cross-ventilation that lobe portion is distributed, makes heat be able to Quick diffusing, has effectively improved the heat dispersion of LED light fixture.
For the light of LED lamp group is utilized effectively, and make the heat of LED chip generation effectively be delivered to each lobe portion, at the center of described radiator, be provided with a base portion raising up; Described LED lamp group is arranged on the top of this base portion.
Air Flow when effectively improving the heat radiation of lobe portion, improves radiating effect, and described lobe portion is outwards extended upward by the root of described base portion, and described heat dissipation channel is axial perforation near the root of described base portion.
As a kind of concrete technical scheme, in described base portion, be provided with a transparent lampshade, described lampshade encloses described substrate and LED chip; Place suitable for reading at described lampshade is provided with lens.By the setting of transparent lampshade, the light that makes to project on reflective surface is softer.This lampshade inwall or outer wall can be smooth surfaces, also can adopt a plurality of continuous facets.And inwall or outer wall adopt a plurality of continuous faceted lampshades to produce more colorful lighting effect.
As a kind of optimal technical scheme, described reflective surface is a sphere.This sphere is a smooth surface, by the reflection generation multiple spot lighting effect of this smooth surface, as adopted a plurality of continuous faceted lampshades to coordinate the luminous point producing with inwall or outer wall, will be more, and effect will be better.And as another kind of scheme, the continuous Mosaic face that described reflective surface is some polygon planes.By rough plane, LED light is reflected, produce more colorful lighting effect.
As a kind of optimal technical scheme, described lobe portion is circumferentially uniform.Make moulding more graceful, process convenient.
Adopt technical scheme of the present invention, the one, improved the radiating effect of LEDG4 light fixture, extended the service life of LED light fixture; The 2nd, from structure, increased the moulding condition of LED light fixture, make lighting effect there is more selection; The 3rd, to the installation of LED light fixture, provide structural facility.
