    Design input

     

    In the planning phase to make product design goals, needs, and to discuss the feasibility of determining .Or upon receipt of customer demands, we can design a lighting products

     

     

    Industrial design

     

    According to the demand of customer, our industrial designer will design different product effect scheme for the customer to choose.

    As shown on the right picture is an industrial design. We will introduce the design process of street light as the example product

     

     

    Mechanism design

     

    Using 3D programmed to make product mechanism analysis, which can reduce product

    quality and increase the cooling capacity, and at the same time we should consider how to

     make manufacture and use convenient.

     

     

    Module thermal anylysis

     

    LED Vf=3.1V , If=0.4A , P=U*I=3.1*0.4=1.24W  (each LED)

    In the EFD software simulation shows that LED Tj is 61.8 ℃, and the production model is

    measured LED Tj 60.8 ℃. The software simulation and practical test results are near

    and far below the LED limit temperature 125 ℃.LED has no effect on life.

     

     

    whole light thermal analysis

     

    LED Vf=3.1V, If=0.4A, P=U*I=3.1*0.4=1.24W (each LED)
    In the EFD software simulation shows that LED Tj is 73.06 ℃, and the production

    model measured LED Tj 69.06 ℃, which show software simulation and practical

    test results are near and far below the LED limit temperature of 125 ℃.LED has

     no effect on life. 

     

    Circuit design

     

    The DC/DC conversion method can effectively save the energy and to

    provide a stable constant current  output for LED. When the LED using the

    driving current up to 400mA, can achieve 112lm light output.

    We use PSPICE to optimize design, used for components selection.

    Before optimization, the drive output is 368-431mA. when the optimization has

    been made, driving current output is in the range of 388-412mA. The

    fluctuations is small at 400mA and its performance is optimized.

     

     

    Design optimization

     

    Based on the above test and analysis, to make the optimization of this

    product again.

     

     

    Produce model

    Before formal opening mould ,model produced and sent to test

    can greatly save time and manpower to avoid waste.
