For solving the problems of the technologies described above, a kind of LED lamp that the utility model proposes, it comprises the radiator of a hollow and the reflector adaptive with this lumen of radiator.The bottom of this reflector is provided with a through hole, and the lumen of radiator bottom is provided with a control circuit board, and this control circuit board is provided with at least one led light source, and this led light source is arranged in the through hole of described reflector.
Preferably, the top of through hole is provided with second reflecting member in the described reflector.
Described second reflecting member can be second reflector, and the bottom of this second reflector is provided with an aperture, and this aperture is over against described led light source; Described second reflecting member also can be lens.
More excellent, can be provided with the heat radiation oil reservoir between described control circuit board and the lumen of radiator bottom.
The inner surface of described reflector can be provided with reflective material layer, and described second reflector can be made into parabolic shape, and its inner surface is provided with reflective material layer.
More excellent, described radiator is the hollow circular cylinder of end sealing, an end opening, its inner surface is the arcwall face adaptive with the outer surface of described reflector.
More excellent, described radiator and reflector can be one-body molded.
Described radiator, reflector and second reflecting member are made by Heat Conduction Material.
Described Heat Conduction Material can be aluminium or aluminium alloy.
The LED that the utility model will produce thermal source directly is fixed on the radiator, has reduced the heat conduction approach, and makes heat distribution as far as possible evenly, improves heat transfer efficiency, reduces the LED junction temperature, improves lamp life; Increase by second reflecting member, adopt a minimum LEDs light source, the light that makes LED send can carry out two secondary reflections, emits light within effective firing angle and adjust, and the direct perforation in the middle of adding can increase bigger luminous flux.Promptly adopt two secondary reflections, can improve light utilization efficiency fully, the center largest light intensity has improved about 20% than similar LED shot-light; Second reflecting member, the center has increased beam orifice, makes full use of its reflection and transmission effect, effectively improves luminous flux, and has effectively reduced dazzle; Aspect heat radiation and light efficiency, all reach or surmount like product.Advantages such as the energy-saving and environmental protection of final further performance LED light fixture, life-span length.
