In order to save energy and electricity, LED has been greatly promoted, but LED requires a power supply driver, which directly affects the lifespan of the LED. Therefore, how to do a good LED driver power supply 9901 is a top priority for LED power supply designers.

The LED driver we refer to includes two types: digital driver and analog driver. Digital driver refers to digital circuit driver, including digital dimming control, RGB full color transformation, etc. Analogical drive refers to analog circuit drive, including AC constant current switching power supply and DC constant current control circuit.

The LED driving power supply 9901 circuit consists of electronic components, including semiconductor components, resistors, and ED as a cold light source. The working junction temperature should not exceed the limit value, and a certain margin should be left in the design. The design of the entire lighting fixture should consider many aspects such as beautiful appearance, convenient installation, light distribution, heat dissipation, etc. It is necessary to find a balance point among many factors, so that the overall lighting fixture is the best. The development time of LED lighting fixtures is not long, and there are not many experiences to learn from. Many designs are constantly improved.

Some LED driver power sources 9901 use outsourced or purchased power sources, and lighting designers have limited knowledge of power sources. They provide more heat dissipation space for LEDs and less heat dissipation space for power sources. Usually, after designing the lighting fixtures, a suitable power supply is found to match them, which brings certain difficulties to the matching of the power supply. Often encountered, due to the small internal space or high internal temperature of the lamp, and the low cost control, it is unable to be matched with a suitable power supply.

Some LED driver power supplies 9901 have power research and development capabilities. Evaluation should be conducted in the early stages of lamp design, and the power supply design should be synchronized to solve the above problems. In the design, it is necessary to comprehensively consider the heat dissipation of LED and power supply, and overall control the temperature rise of the lighting fixtures, in order to design better lighting fixtures.

The selection of outsourced power sources mainly depends on the voltage range of constant current and constant current. The constant current value is selected as the lower standard current of the LED. The selection of voltage range should be moderate, and try not to choose a larger range to avoid power waste.
