X. In this way, the new projector uses an auxiliary lighting module to turn the bulb on and disable the microprocessor before the bulb is turned on to avoid the influence of high-voltage noise on the microprocessor, thereby reducing the failure rate. 6 M299306 [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be apparent from the following detailed description of a preferred embodiment of the accompanying drawings. Since the aforementioned high-voltage noise only occurs when the bulb is turned on, once the lamp is turned on, the high-voltage noise does not appear after the bubble is turned on, so the new projector is such that the micro-processor and the processor are no longer responsible for lighting work and add one. The component performs the lighting work and disables the processor at this & daytime to effectively avoid the microprocessor being subjected to high voltage impurities> (4) interference H as shown in Fig. 2 'The preferred embodiment of the novel projector has - power supply 21. A microprocessor 22, a light bulb 23, a lighter 24, an input unit 25, an auxiliary lighting module 26, and a heat dissipation unit 27. The power source 21 is used to provide the power required for the projector internals 22 to 27 to operate. The power supply 21 of the present embodiment, a power supply, and the power supply is received by the plug-in 211 to be converted into an appropriate power supply to the corresponding component, for example, about 375V power is supplied to the lighter 24 and about 15V power reading.孰 unit η and so on. - The microprocessor 22 is used to coordinate the operation of the projector. The light bulb is high and the gas discharges the light bulb, and the lighter 24 is electrically connected to the light bulb 23, and the micro processing: 22 and the auxiliary lighting module 26 drive the light bulb 23 to open and close in a timely manner. The input unit 25 transmits control commands for the user to the microprocessor 22 and the auxiliary lighting module 26. The input unit 25 can be at least - a control button provided on the projector and a remote controller. The control command contains two ^7, - shutdown command, - power on command and - standby command and so on. The auxiliary lighting module 26 receives the control command from the input unit 25 and 7 M299306 is electrically connected to the lighter 24 and the microprocessor 2 and the light bulb 23 to receive the control unit 2; 23 to open the relevant control command (eg Point (4) corresponds to the generation of -_, the number to the lighter 24 with two or two help: pass, and day d 7 lights for 24 drives / turn on, while disabling the microprocessor 22 t ί α ^ stop. too cautious丨山4 σ 22 until the bulb 23 is turned on. In the present embodiment, the auxiliary lighting module 26 has _ 26^ and - the first switch 262. 4 auxiliary lighting control unit auxiliary lighting control unit 261 is electrically connected The power source 21 operates to receive power, 21:: integrated circuit (PIC) and X to supply 21 supplied power. The auxiliary light controller 261 is electrically connected to the input unit & point (1) 4. First The switch 262 is controlled by the auxiliary lighting control unit 261 to control the serial switch 262 to be connected in series to the line of the power source 21 to the 4 processor 22. The _ terminal of the finger-switch 262 is electrically connected to the power supply 21 to the microprocessor 22. When the auxiliary light control unit 261 receives the control related to the opening of the light bulb 23, if the light is received from the input unit 25 The auxiliary lighting control 261 controls the first switch 262 to close the circuit to disconnect the power supply 21 from the microprocessor 22, so that the power supply 21 does not supply power to the microprocessor u to enable the microprocessor 22, and correspondingly generates a light signal. To the lighter 24, let = the lamp i drive the bulb 23 to be turned on. After the bulb 23 is turned on, the auxiliary lighting control unit 26U empties the first 262 to turn on (〇N) to restore power to the microprocessor 22 by the power source 21 to enable the microprocessor 22. Thus, at the beginning of the lighting During high-voltage noise, the microprocessor 22 is disabled and not activated. After the noise disappears, the microprocessor 22 is started to prevent the microprocessor h from being abnormal due to high noise. In order to effectively reduce the projector's failure rate of 8 M299306. When the microprocessor 22 is enabled, the projector enters a working mode, and the microprocessor 22 detects the lighting condition of the lighting device 24 to obtain the light bulb. 23 If it is normally turned on, for example, when the lighter 24 or the light bulb 23 is faulty, the microprocessor 22 will generate a warning signal to inform the user. The instructions related to the light bulb opening include, in addition to the lighting command, Other commands, such as a power-on command, and a lighting command, in addition to being input by the input unit, may be generated by the utility processor 22 to the auxiliary lighting control unit 26 i. The heat dissipation system 27 is disposed around the light bulb 23 to assist in eliminating the light bulb 23 . around The heat dissipation unit 27 of the embodiment is a fan. Further, the projector has a standby mode in addition to the working mode when the power is turned on. The microprocessor 22 sets the projector to enter the standby mode according to the setting, for example, according to the user. The input standby command or setting the projector does not work for more than one preset time. 'To: the consumption of painful power. - Generally, in the standby mode, the bulb 3 is turned off, that is, the power is saved. Therefore, the auxiliary lighting of this embodiment The mode is also more controlled by the auxiliary lighting control unit & 261. The second switch, the 263 and the second switch 264. The first-off switch 263 is connected in series to the power supply line of the power source 21 to the lighter 24. The second switch 263 is electrically connected to the power supply 21 and electrically connected to the other end of the lighter 24. The second switch 264 is connected in series to the power supply line of the power supply 21 to the heat dissipation time το27. When receiving the lighting instruction, the control unit 261 first controls the second, the second switch 263 and the third three switch 264 to be turned on, so that the power supply 21 supplies power to the lighting ... Β, and the heat dissipating unit 27, so that the heat dissipation starts immediately Work, auxiliary lighting control unit 26 丨逄 light signal to the lighter 24, let the light 4 drive the light bulb 23 to turn on. However, when the M299306: Tian Xu enters the standby mode, the microprocessor 22 correspondingly generates a standby auxiliary lighting control unit 261. At this moment, the auxiliary The lighting control unit ^ correspondingly generates a light-off signal to the lighting device 24 to drive the lighting device 24 to close the package 23, and then closes the first switch 262, the second switch 263 and the third switch 264 to stop the power supply. 21 pairs of lighting device 24, microprocessor 22 and heat supply tl 27 to reduce power consumption. In addition, the second switch 263 and the third opening 264 can be integrated into the power source 21 and be auxiliary lighting The switch is controlled by the unit 261, and the power source 21 determines whether to power the lighter 24 and the heat sink unit 27 according to the opening and closing of the switch. Different from the conventional standby mode, only the bulb 23 is turned off. In the standby mode of the embodiment, the power consumption of the microprocessor 22, the lighter 24 and the heat dissipation unit 27 is more suspended to achieve a more power saving effect. In the standby mode, the control command input from the input unit 25 is received by the auxiliary lighting control unit 261, and assists the projector to return to the operational mode upon receiving the control command. In detail, once the auxiliary lighting control unit 261 receives the control command input by the user in the standby mode, the auxiliary lighting control unit 261 turns on the second switch 263 and the third switch 264 to generate the lighting k number. The lighter 24 is turned on to turn on the bulb 23, and then the first switch 262 is turned on to enable the microprocessor 22 to be used by the microprocessor 22 to coordinate the operation of the projector 23. In order to eliminate the unfavorable effect of the heat dissipation unit 27 when the heat dissipation unit 27 fails to provide the heat dissipation function, the projector of the embodiment further adds an auxiliary heat dissipation module 28 to continue to supply power for a predetermined time when the power source is interrupted. The heat dissipation unit 27 causes the heat dissipation unit 27 to continue to operate to instantly cool the bulb 23 10 M299306. The auxiliary heat dissipation module 28 of the embodiment has an auxiliary heat dissipation control unit 281, a battery 282 and a fourth switch 283. The preset length of time can be adjusted according to the designer's needs, such as four minutes. The battery 282 is used to provide the power required for the heat dissipation unit 27 and the heat dissipation assist control unit 281 to operate when the power is off. The battery 282 of this embodiment is a rechargeable battery. One end of the fourth switch 283 is electrically connected to the bridge between the heat dissipating unit 27 and the third switch 264, and the other end is electrically connected to the battery and can be opened and closed by the auxiliary heat dissipation control το281. In this embodiment, the auxiliary heat dissipation control unit 281 is a programmable integrated circuit and can be operated by the power supply 2 or the battery 282 to supply power. The auxiliary heat dissipation control unit 281 is configured to read whether the power supply 21 is powered to the heat dissipation unit 27. The detection result corresponds to controlling the opening and closing of the fourth switch 283. The auxiliary heat dissipation control unit 281 is electrically connected to the power supply line of the power source 21 to the heat dissipation unit A 27, and when the power source 21 $ is powered, when the power supply is not powered, if the plug 2i i is unplugged or suddenly disconnected The auxiliary heat dissipation control unit 281 controls the fourth switch M3 (such as turning on the fourth switch, 3) to supply power to the heat dissipation unit A 27 by the power 16282 for a preset time, so that the monthly ... single το 27 performance work for a period of time Instantly cool the temperature of the bulb η to avoid the unconstrained material 231= short due to the lack of immediate cooling, and the opening and cooling unit 281' of the four-switch 283 when the start-up has exceeded the preset time At the same time, the supply of auxiliary power and power is suspended, so that the battery 282 no longer consumes power.

In detail, when the power supply ^ is supplied to the heat dissipation early t27, the third switch 264 is turned on by the auxiliary lighting control unit, and is electrically connected to the auxiliary heat dissipation control of the power supply between the power supply 21 and the heat dissipation unit 27. The unit 281 can be powered by the power source 21 to start operation to control the fourth switch 283 to be turned on, so that the power source 21 can be powered to the battery 282 via the fourth switch. When the battery 282 is fully charged, the power from the power source 不再 is no longer received for charging. At this time, the auxiliary heat dissipation control unit 281 is still electrically connected to the parallel battery 282 and the power source 21. When the power supply 21 stops the power supply, the battery 282 immediately supplies the power required for the auxiliary heat dissipation control unit 281 to operate. At this moment, the auxiliary heat dissipation control unit A 281 starts to count when the power change is detected, and each auxiliary heat dissipation control unit 281 counts the time to close the field. In order to prevent the battery 282 from being improperly consumed, the battery 282 is used to stop the power supply of the battery 282. In this way, the auxiliary heat dissipation module 28 can automatically charge the battery 282 when the power source 21 is normally powered, and is provided to the heat dissipation unit 27 when the subsequent power source 21 is interrupted. According to the foregoing, in the new projector, the microprocessor 22 is disabled first and the auxiliary lighting module 2 61 is used to perform the rubbing.仃^bubble 23 is turned on, and after the bulb 23 is turned on, it is sent to the microprocessor 2 2 to avoid the high-voltage noise at the beginning of the operation, and the high-voltage noise at the beginning of the opening is Effectively reduce the life of the projector's fish machine; in addition, in the hand-extension and bamboo-type, the auxiliary lighting module 261 f disables the microprocessor 22 to achieve more power-saving effect; Interrupt power supply to the heat sink unit 27 士士, ^^ Power Guard' auxiliary power module 2 8 instant power supply to 12 M299306 heat sink unit 27, so that the heat sink unit 27 can continue to operate - evaluate the slave day T, to achieve better heat dissipation And effectively extend the life of the bulb 23. ▲ However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change of the novel application and the new description content is Modification. : All are still within the scope of this new patent.
