Ripple sensing lamp module can simplify production procedure and test link in production link, greatly improve production efficiency, and at utmost
It is inconsistent to reduce the distance of reaction of microwave induced lamp caused by uncontrolled factor influence in production process, and false triggering etc. is asked
Topic.
Integrated structure design of the present utility model is compared with the microwave induced lamp of routine possesses fairly obvious advantage.It is micro-
The integration of ripple sensing lamp is the pcb board 1 of integrated design with being controlled and being designed by way of standardization modularization
Production procedure, and good control product running situation and uniformity can be simplified.Because control process module 3 is to analog signal
The simulations such as (IF intermediate-freuqncy signals) is analyzed, information processing and algorithm calculate design, and the electronics compared to logical calculated produces
Product, test environment can it is cumbersome a lot.The microwave induced lamp uses integrated design, and one time paster is completed, without subsequently in work
People's manual welding, improves Product Precision, and rosin joint or the improper caused inductor of wire jumper welding are reduced during assembling
The problems such as induction sensitivity is inconsistent, largely improve uniformity of the microwave induced lamp in finished product test and reliable
Property.
It is further of importance that the integrated design of microwave induced lamp, facilitates original light fixture again in R ＆ D of complex
Design and modification, original traditional lamp panel structure can be changed rapidly according to different clients requirement, it is not necessary to consider that 5.8GHz is more in light fixture
The riding position of Pu Le probes 2 and control process module 3, the light fixture that the pcb board 1 of integrated design can easily with various structures
With reference to, from common LED lamp to microwave radar sensing lamp all can conveniently combine.The pcb board 1 of integrated design can apply to existing
