A kind of LED illuminator; Comprise lamp pearl, radiator, base and cover body; Described radiator is the hollow cylindrical straight tube that is communicated with up and down, and an end of described radiator is connected on the base, and radiator is provided with the air outlet that communicates with extraneous air near an end of base; Described lamp pearl is fixed on the outer wall of radiator; Cover body covers lamp pearl and radiator and is provided with the passage that the hollow position with radiator adapts, and an end of cover body links to each other with base, and the inwall of the other end and radiator joins.
For making the utility model play better technique effect:
Technical scheme further is that above-mentioned lamp pearl is to be fixed on the outer wall of radiator through substrate.
Technical scheme further is that the lamp pearl of installing on the above-mentioned radiator vertically is arranged in the lamp group, and the radiator outer wall at each lamp group place forms the plane.
Technical scheme further is that the inwall of above-mentioned radiator is provided with radiating fin.
Technical scheme further is that above-mentioned base outer wall is provided with screw thread or is used for the lug of buckle.
Adopt the beneficial effect that technique scheme produced to be: a kind of LED illuminator of the utility model directly is installed in the lamp pearl outer wall of radiator; The inwall of radiator utilizes the cross-ventilation heat radiation; The lighting area of the utility model is increased greatly; And do not conflict mutually with the required area of heat radiation, both sides can both be satisfied, and realize better heat exchange effect and illuminating effect simultaneously.
