Improve the stability of LED lighting

Constant current driver can make the light emitting diode work in a fixed current mode, thus high brightness stability.

The brightness of LED light emitting diode with the current size of the light emitting diode, and manufacturing, the voltage and current curves are slightly different, so the brightness LED often change with the power supply voltage to stable. In order to maintain the stability of the light, a constant current driver is needed. The constant current driver can make the light emitting diode work in a fixed current mode, so the brightness stability is high. The constant current driver also allows the led to work under a certain current for a long time.

T6316 is a constant current driver, it is a 4 channel constant current LED driver, the output current can be determined by external resistors. T6316 has a precision of 6% + current and channel + + 3% matching accuracy, can be used for street lamps, lamps and other lighting equipment. In order to save energy, the design of the system needs to consider the constant current drive across the pressure between 0.5V~2V. Due to the long duration of the light emitting diode working under constant current, the pressure drop is slightly decreased.

The light emitting diode is a diode of semiconductor material, which is composed of PN interface. When the forward voltage is applied, the electron and the hole combine to release energy in the form of photon, so it has the characteristic of luminescence. And its light source in the vicinity of the PN interface within mm, the wavelength of light depends on the characteristics of the material and have different luminous colors, red, yellow, green, blue light-emitting diodes.

The luminous intensity of the LED can be adjusted by the working voltage (current). The brightness of the LED increases with the increase of the current in the large operating current range. Since 2010, Europe, the United States, Japan and other advanced countries have begun to enforce the ban incandescent lamp decree, the statute was based on the limitations of low luminous efficiency of the light source. Incandescent bulbs are disabled, replaced by light sources, including light bulbs, cold cathode tubes, LED, etc.. But in the future, such as consider the restrictions on harmful substances, LED light source will be the best choice.
