The BLU 200 further includes a switch mode power supply (SMPS) i5〇, which is provided between the external power source 17〇 and the ventilation fan portion 130 for receiving AC power and is connected at the conversion = AC power is Dcf| constant power (12 volts) The supplied AC power is then supplied to the ventilation fan portion 13A. A backlight panel 105 is provided between the work platform and the workbench and has a space for accommodating a plurality of components for the illumination-workbench, on which a flat display panel is loaded. The space of the backlight panel 丨〇 5 accommodates the fluorescent lamp portion 11 〇, the stabilizer portion 120, the ventilating fan portion 13 〇, the SMps 15 〇, and the ssr just. The spotlight portion 110 includes a plurality of lamps constituting at least two segments, each segment including at least two lamps 111. The shell of the zone 2 is independently controlled. Each of the lamps 111 is lit by discharging in a low-pressure mercury vapor. That is, since the voltage required for discharge drops when the current flows, % is applied with a constant voltage to cause discharge. = As shown in Figure 6, 24 lights lu make up the fluorescent part ιι〇. Specifically, 24 lamps in constitute four segments a, B, c, and d. Since the four segments A, B, C, and D are independently controlled, the brightness of the four segments A, B, C, and D can be independently controlled. Each of the lamps 111 constituting the egg light 110 is serially connected to a stabilizer 12A including a plurality of stabilizers 121. Preferably, each of the stabilizers 121 is connected in series to the two lamps 111. Therefore, the stabilizer portion 120 connected to the fluorescent lamp portion 110 including 24 lamps η includes 12 yokes 121. The stabilizer portion 120 prevents excessive current from flowing into the fluorescent lamp portion 110 to damage the fluorescent lamp portion 110. That is to say, the light current generated when the discharge is: (1) can damage the lamp 丨 22 to prevent excessive current increase. Each of the stable electrodes 121 can be a metal resistor, but it is usually a choke coil, and although the electric current is large, the choke coil hardly generates heat.提供 Provide a general purpose at the side of the back wire 1〇5, so that the self-stabilizer part (4) and the glory part are not; Ventilation fan The fan section 13° also includes the 赍 从 立 立 / / , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Use - stable DC power to operate each of the LEDi33H ^ ^.

That is, the SMPS source 70 receives human 匸 power having a voltage of 22 volts to supply 1282715 18960 pif U power to the stabilizer portion 12G and the ventilating fan portion i3 〇, and the AC power received by the household is stable after 额定 C rated power. = AC power is supplied to the ventilation fan section (10) to operate the fan i3i and the LED 133. The ac work with 22 volts voltage supplied from the external power source 170 is connected in series to the fluorescent lamp section of the stabilizer section m. . In phase two, the stabilizer portion 12 connected in series to the fluorescent lamp portion 11Q can be connected to the external power source 17 by means of the interface (10). A solid state relay (SSR) M0 is provided between the connection 稳定16〇 and the stable:丨, 120 for control = power supply shut-off operation, and the power_direction (4) is connected to the stabilizer portion 120 of Π0. ...140 is an electrical relay, not an electromechanical relay that performs a simple on/off function rather than a phase control function. In addition, the ssri4〇 prevents the current from quickly sighing the long rides and reducing noise. Therefore, when power is applied from the external power source 170 to the ssr 14 switching operation, the SSR 140 is turned on to transfer the applied power to the stabilizer portion (10) of the string lamp 11G.

Then, the ventilation fan 131 rotates and the LED 133 emits light. Further, all of the fluorescent lamps of the fluorescent lamp portion 110 are illuminated with constant light. The main photon adjuster 192 is turned on, and the lamp 111 is adjusted to emit light in a desired candela. In this case, there may be a change in luminosity in individual sections of the fluorescent lamp section 110. Therefore, it is necessary to individually adjust The illuminance of the lamp 111 in the section where the luminosity is to be compensated. The section of the luminosity change to be compensated is selected by the 14 1282715 18960pif selection switch I93. In order to precisely adjust the luminosity of the lamp in the section to be compensated for luminosity change, the manipulator The fineness adjuster 194 is turned on to compensate for the required change in luminosity. As described above, the fluorescent lamp portion 110 is divided into sections and independently adjusts the luminosity of the sections. Therefore, it is possible The fine adjustment test plane shows: the money changes that occur and may focus on testing a specific segment. It is intended to concentrate the test segment eight by reducing the luminosity of segments B, c and D by reducing segments A, C and Focusing on the luminosity of D to test section b; concentrating test section c by reducing the luminosity of sections A, B and 〇, and concentrating test section D by reducing the luminosity of sections A, B and c According to the segmented backlight unit of the present invention, the -SMPS and an SSR are used to current control a ventilation fan portion, a stabilizer portion, and a light portion to reduce the _ phenomenon. Due to current control, even when ^ The low-luminosity filament also reduces the flashing image. Therefore, the lamp of the backlight keeps the problem and prevents the xenon lamp phenomenon. In addition, since the power line used is short and simple, the noise is reduced. , control the fluorescent lamp part of the time plane riding and adjust the luminosity change ^ In addition, the function of the external controller includes the configuration of the backlight segment backlight unit and reduces its weight. Therefore, it is possible that the height = Use efficiency ^ significantly reduces f In addition to the time required for the parts, as well as the work. In addition, because a stabilizer is connected to two fluorescent lamps, the number of s golden lights is reduced by half. Therefore, the use of the allowance to the interior space of the moonlight panel is provided.
