The specific embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment of radiator, structure, feature and effect thereof according to a kind of LED of the enhancing light fixture heat loss through radiation the utility model proposes, be described in detail as follows.
Consulting shown in Fig. 1, is the structural representation of the radiator that strengthens LED light fixture heat loss through radiation of the present utility model.The radiator of this enhancing LED light fixture heat loss through radiation comprises heat-dissipation lamp housing 1, heat conduction core 2 and LED substrate 3; Wherein, this heat conduction core 2 embeds in heat-dissipation lamp housing 1, fits tightly, and both closely cooperate, and reduces thermal resistance.The lower surface of this heat conduction core 2 and LED substrate 3 fit tightly, can be with heat-conducting glue bonding and with screw fastening, keep the state that fits tightly, thereby formation have the radiator of heat conduction and heat radiation.On this LED substrate 3, be fixed wtih LED lamp, this LED substrate 3 generally uses aluminum.
In the time manufacturing the radiator that dispels the heat good, need to there is the material of high thermal conductivity coefficient and high radiation coefficient simultaneously, but up to the present, also not find that independent a kind of material has high thermal conductivity coefficient and high radiation coefficient simultaneously.The utility model is for addressing the above problem, the way adopting is to be greater than 0.8 with radiation coefficient, thermal conductivity factor is greater than the heat-conducting plastic of 2W/mk and manufactures heat-dissipation lamp housing 1, be greater than the metal material manufacture heat conduction core 2 of 80W/mk with thermal conductivity factor simultaneously, such as aluminium, copper etc., but the cost of copper is high, generally select the aluminium that cost performance is suitable.It is base material that above-mentioned heat-conducting plastic is selected engineering plastics and general-purpose plastics mostly, as PPS, PET, ABS, PP, PA(Nylon), the high-molecular organic material such as EP makes.
