Find according to market survey, the damaged condition analysis of each LED lamp model of market now, reach 40000-50000 hour the service life of LED, but the life-span of the power drives of support LED is the service life of too late LED lamp far away, in use fail to reach its best result of use so the LED lamp takes place, also just slackened the superiority of effectiveness of LED lamp indirectly in market competition.Existing design will be made easy modular organization between LED lamp and the power drives, its improvement point that causes just has under the situation of damage in power drives, to change than the power drives of low Material Cost, thereby keep the higher LED lamp of Material Cost, can improve the existing cost performance of LED lamp on market so greatly.But this structure also has its drawback accordingly, promptly by plastics power drives shell with power package after, the heat energy that power drives itself is produced can not in time distribute, thereby the life-span subaverage that also causes power drives, if and use metal shell, can produce electric conduction phenomena again, be very big hidden danger to safety.
The utility model content
Above-mentioned defective at the prior art existence, technical problem to be solved in the utility model is the power drives encapsulating structure that proposes the LED lamp that heat distributes easily, safety coefficient is high of a kind of power drives generation itself, and proposes to have the LED lamp that aforementioned power source drives encapsulating structure.
In order to solve above-mentioned technical problem of the present utility model, the power drives encapsulating structure of the LED lamp that the utility model provides comprises power drives, and its innovative point is, also comprise the thermosetting plastics member, and power drives is packaged together as inserts and thermosetting plastics member.
As optimal technical scheme of the present utility model, above-mentioned thermosetting plastics member comprises the first thermosetting plastics member and the second thermosetting plastics member, the pcb board of power drives is packaged together as the inserts and the first thermosetting plastics member, the first thermosetting plastics member outside embeds the aluminium inserts as heat radiating material, and the aluminium inserts outside is packaged with the second thermosetting plastics member.
A kind of LED lamp that the utility model proposes, comprise radiator body, power drives and thermosetting plastics member with plastic body and aluminium inserts, power drives is packaged together as inserts and thermosetting plastics member and constitutes the power drives encapsulating structure, and this power drives encapsulating structure embeds in the radiator body and radiator body is packaged together.
Power drives encapsulating structure with respect to existing LED lamp the utlity model has following characteristics and advantage:
1) the utility model is put into mould shot moulding with power drives as inserts, makes product component quantity reduce half, deducts assembly process, helps client's cost control and Material control.
2) because the thermal conductivity factor of the thermosetting plastics that the utility model uses is higher, and realized integratedly after the power drives moulding, make the conduction accessibility of heat, improved the radiating effect of power drives; And thermosetting plastics can not produce electric conduction phenomena, the safety coefficient height.
3) because the utility model shot moulding so also be to reduce much, has been lacked the bigger problem of volume that original trim designs produces on the difficulty of research and development, also be that cost has been had good control.
