The LED we are talking about is a cold light source. The operating junction temperature cannot exceed the limit, and a certain margin must be left in the design. The design of the entire luminaire should consider many aspects such as beautiful appearance, convenient installation, light distribution, heat dissipation, etc. It is necessary to find a balance among many factors, so that the overall luminaire is the best. The development time of LED luminaires is not long, and you can learn from them Not much experience, many designs are constantly improved. Some LED luminaire manufacturers use external power sources or outsourcing. The luminaire designer does not know much about the power supply, and it has a large heat dissipation space for the LED and a small heat dissipation space for the power supply. Generally, it is necessary to find a suitable power supply to support the lighting after designing it, which will bring certain difficulties to the matching of the power supply. It is often encountered that due to the small internal space or high internal temperature of the luminaire, and the low cost control, it is impossible to allocate a suitable power supply. Some LED lamp factories have power supply R & D capabilities. Evaluation is performed at the beginning of the design of the lamp, and the design of the power supply is carried out simultaneously to solve the above problems. In the design, it is necessary to comprehensively consider the heat dissipation of the LED and the power supply, and control the temperature rise of the lamp as a whole, so as to design a better lamp.

 

You can pot the LED driving power supply, install aluminum substrate cooling aluminum sheet, and then have a fever, install a cooling fan, and improve the cooling capacity of the LED driving power supply.

 

 

 

Through the above description, the design is strictly guarded, and the products produced are durable and of good quality. We mainly look at the constant current and constant current voltage range in the choice of externally purchased power supplies. The constant current value is selected as the standard current of the LED. The selection of the voltage range should be moderate. Try not to select a larger range to avoid wasting power.
