For achieving the above object, the technical solution adopted in the utility model is: a kind of high-powered LED lamp of high efficiency and heat radiation, comprise many group LED chip, lamp housing and lampshades, it is characterized in that: the truncated cone-shaped radiator, the inside that also comprise hollow structure are provided with the control cabinet of power supply or connection line and the rubber ring for sealing, described truncated cone-shaped radiator arranged outside has lamp housing, the upper end of described truncated cone-shaped radiator is fixedly connected with described lamp housing, between described truncated cone-shaped radiator and described lamp housing, be provided with rubber ring, described envelope inner wall is provided with the reflecting plate for light being reflected to aggtegation, the bottom of described lamp housing is provided with lampshade, described truncated cone-shaped radiator inwall is provided with the many groups of fins that produce heat for LED chip when work described in Quick diffusing, described truncated cone-shaped radiator outer wall is provided with connecting line draw-in groove, described truncated cone-shaped radiator outer wall is provided with many group LED chips, described truncated cone-shaped radiator upside is fixedly connected with described control cabinet by many hollow columns, described in every group, LED chip is all connected with described control cabinet by the electric wire through connecting line draw-in groove and hollow column.
The high-powered LED lamp of above-mentioned a kind of high efficiency and heat radiation, is characterized in that: described lamp housing is the bowl structure that Open Side Down.
The high-powered LED lamp of above-mentioned a kind of high efficiency and heat radiation, is characterized in that: described reflecting plate surface is coated with highly reflecting films.
The utility model compared with prior art has the following advantages:
(1) high-powered LED lamp of this high efficiency and heat radiation is reasonable in design, simple in structure.Utilize the principle of natural convection air, can realize the Quick diffusing of heat; And at the outer wall of truncated cone-shaped radiator, many group LED chips are set, make LED light fixture have larger power, improved illuminating effect.
(2) the high-powered LED lamp volume of this high efficiency and heat radiation is little, lightweight.For radiating fin being set in truncated cone-shaped radiator inside, reduce light fixture volume, alleviate light fixture weight.
(3) high-powered LED lamp of this high efficiency and heat radiation is provided with the reflecting plate that light is converged to effect, and is coated with highly reflecting films on reflecting plate surface, can realize good aggtegation, good illumination effect, long service life to light.
(4) a lot of parts of the high-powered LED lamp of this high efficiency and heat radiation are all convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
