Technical field
The present invention relates to a kind of LED lamp, be specifically related to the processing method of a kind of LED lamp radiator, this LED lamp radiator and be equiped with the LED lamp of this radiator.
Background technology
The heat radiation of LED lamp is more and more paid attention to by people now, in the work of LED lamp, can produce a large amount of heats, these heats can not distribute in time, will cause that Embedding Material is aging, the series of problems such as chip light decay acceleration, the bad junction temperature of dispelling the heat will raise, and 10 ℃ of life-spans of the every reduction of temperature can extend 2 times.Therefore, existing LED lamp is all equipped with radiator, and pcb board directly and radiator good contact, falls the dissipation of heat producing in the work of LED lamp.Existing radiator generally includes base plate, top board and is vertical at the multi-disc fin between base plate, top board, between adjacent fin, forms air channel, obviously the radiator heat-dissipation effect of this spline structure bad.Another is to only have base plate and be vertical at the multi-disc fin on base plate, between adjacent fin, form air channel, although such structure makes the heat discharge of easily rising, but so easy temperature distortion of structure fin, changed the structure of heat dissipation channel, thereby make in use procedure, heat dispersion is variation gradually, can not play good thermolysis.And the base plate of radiator and fin fixed form trouble in existing LED lamp, each sheet fin is fixed on base plate by the variety of ways such as screw or welding are piecemeal, greatly increases workman's labour intensity, and the production cost of product is increased.
Summary of the invention
For solving existing LED lamp radiator heat-dissipation poor performance in background technology, fin is fixed unreliable and is held yielding problem, the invention provides processing method and the LED lamp of a kind of LED lamp radiator, this radiator.
Technical scheme of the present invention is: a kind of LED lamp radiator, comprise base plate and be vertical at the multi-disc fin on base plate, between adjacent fin, form radiating groove, the top of described fin is provided with the top board parallel with base plate, described top board is provided with and is connected with radiating groove and the breach of vertical radiating groove, and described base plate, fin and top board are integral type structure.
As a modification of the present invention, the bottom of described fin is provided with rinforcement bar near base plate place.
As a further improvement on the present invention, the top of described fin is provided with the air channel being connected with top board breach, and described air channel is connected each radiating groove.
A processing method for LED lamp radiator, described LED lamp radiator is processed according to the following steps: 1. choose metal material to be processed; 2. the face of material to be processed of take is base plate, stretched fin and top board, and make to form radiating groove between adjacent fin; 3. on top board, process and be connected with radiating groove and the breach of vertical radiating groove.
As a modification of the present invention, stretched rinforcement bar in stretched fin.
As a further improvement on the present invention, on processing top board during breach, breach the degree of depth thickness that is greater than top board make simultaneously at the top of the fin processing air channel that different radiating grooves are communicated with of sening as an envoy to.
A LED lamp, comprises housing and a plurality of lamps source, correspondingly on each lamp source is provided with above-mentioned LED lamp radiator.
As a modification of the present invention, described housing is provided with steam vent, the parallel radiating groove setting of described steam vent.
The invention has the beneficial effects as follows, the temperature distortion of fin has been avoided in the setting of fin top top board, and on top board, the structure of breach can not only laterally be discharged hot gas from steam vent, and can discharge from the top board breach at top.In the present invention, by base plate, fin and the machine-shaping of top board one, make the easy to process of product, greatly reduced process time and processing cost, and when taking into account thermal diffusivity, also avoided the deformation in fin work.
