A partial illuminator is a luminaire that increases the illumination of a working part. Its function can be to strengthen or supplement the lighting on the basis of general lighting, or it can be used as temporary lighting in places where lighting is...
1. Power reserve and derating requirements are not considered 2, does not consider the variation range of LED lamp bead Vf, resulting in low efficiency of the lamp, even unstable operation 2, does not consider the variation range of LED lamp bead Vf,...
1. Resistor-capacitance: The scheme is simple, the device is small, the cost is low, and the constant current is not constant. 2. Non-isolated power supply: moderate cost, IC constant current, but there is also the danger of leakage caused by breakdo...
01. Check if the power supply is working properly, and the indicator light is not lit. If it is not lit, please check if the power is connected. 02. Check whether the power cord of the lamp bead is connected to the positive and negative poles of the ...
A. Optical system (1) LED luminaire optical system generally consists of LED chip and lens composed of LED unit or LED unit array. The array is sometimes arranged on a flat aluminum substrate, or on a protruding or concave shaped substrate. The lumin...
LED driver: A device that contains a power supply and LED control circuitry to operate the LED package (component), or LED array (module) or LED lamp. Interpreting the above definitions related to LEDs provides a basis for us to distinguish between L...
Like traditional light source luminaires, LED luminaires are also hot. The heat of LED luminaires comes from the loss of LED photoelectric conversion and the LED drive power. Different from the principle of traditional electric light source illuminat...
(1) The AC is connected to the DC output of the driver, causing the drive to fail; (2) The AC is connected to the input or output of the DC/DC driver, causing the drive to fail; (3) The constant current output terminal is connected with the modulatin...
