Description

A kind of LED floodlight

Technical field

The present invention relates to a kind of lighting field, particularly a kind of LED floodlight that is applicable to that room lightings such as factory floor, office, hotel, market, conference hall, corridor are used.

Background technology

At present, the development speed of China LED illuminating lamp is very fast, and application is more and more wider; The integrated level of illuminator chip is also more and more higher, and the monomer chip has reached powerful level.Yet, the design of the lamp type of high-power LED illuminating lamp mostly is designed to one to illuminating lamp and lampshade etc. because of many reasons such as the radiator volume is big, Heavy Weights, with original incandescent lamp or electricity-saving lamp with the LED illuminating lamp when alternative, need replacings simultaneously such as light fixtures, even some also needs change finishing.Therefore, the high-power LED illuminating lamp lamp type that is used for outdoor lighting at present is more, for example: LED street lamp, LED shot-light, LED Lawn lamp etc.And indoor LED illuminating lamp is lamp types such as small-power, the low light level, ornament lamp mostly.Particularly with incandescent lamp, the electricity-saving lamp volume is similar, and not changing original light fixture, can directly to replace the high-power LED illuminating lamp lamp type of incandescent lamp or electricity-saving lamp almost be blank.

Summary of the invention

In view of the deficiency that prior art exists, the high-power LED illuminating lamp volume is big, the problem of Heavy Weight in order to solve in the present invention, has adopted the LED illuminating lamp radiator of autonomous Design.In order to solve the lamp body problem related with light fixture, overall structure, reducing sleeve, switching pad, lens, lens jacket to the LED illuminating lamp design, mix light emitting source chip, constant-current supply and the existing universal socket of high integration, form a kind of LED floodlight.

The present invention for achieving the above object, the technical scheme of being taked is: a kind of LED floodlight, comprise LED light emitting source, constant-current supply, lamp screw base, it is characterized in that: also comprise ball bubble mirror, reflection frame, the first switching pad, heat radiation axle, fin, the second switching pad, reducing sleeve, described ball bubble mirror is a half elliptic, one end is a spherical, and the other end is a round empty cavity, is provided with public seam in the upper surface of round empty cavity; The described first switching pad, the second switching pad are round sheet, are provided with several positioning through hole on circular face; Described reflection frame is a round frame, and round frame simultaneously is the circle parabolic shape, and the parabolic center of circle is a through hole, and another side is a circular groove, is provided with boss in groove, is provided with locating hole on boss, is provided with the female seam of a circle on reflection frame one end cylindrical; Several pieces described fin are separately fixed in heat radiation several U-shaped inserted slots that are provided with and constitute radiator, the described first switching pad, the second switching pad symmetry respectively are fixed on the both ends of the surface of radiator, described LED light emitting source is fixed on the first switching pad, on the boss of the first switching spacers in reflection frame upper groove, described ball bubble mirror is connected together by female seam on public seam and the reflection frame and reflection frame; Described constant-current supply is embedded in the reducing sleeve, and on the chamber inner convex platform of the described second switching spacers in reducing sleeve one end round empty cavity, the running-on of the described lamp screw base and the reducing sleeve other end fixes.

The invention has the beneficial effects as follows: this LED floodlight, by independently lamp type design, solved the disjunctor problem of high-power LED illuminating lamp lamp body and light fixture, carry out and divide body structure; The high-power LED illuminating lamp heat dissipation metal body of the present invention design in addition, dwindled the volume and weight of radiator, make LED illuminating lamp lamp body can directly substitute original incandescent lamp or the electricity-saving lamp that uses, avoided changing light fixture even changing the inconvenience and the waste of fitting up and bringing, realized the purpose that directly substitutes.Adopt ball bubble mirror, its special profile has increased the scattering area and the light transmittance of light.
