Ask: what is the cooling requirements of UHP lamp?

Answer: In the specifications of light, the "test and working conditions," there is a light in different parts of the temperature requirements, including molybdenum-chip pinout, the electric arc tube and joint. At the same time we prepare the design on the cooling of the guiding document - "UHP lamps cooling / temperature measurement applications guide." Customers in the design of tailor-made to order when the measurement temperature of the cooling Samples lamp design evaluation and optimization.

Ask: what is the cooling requirements of UHP-driven power?

A: At the specifications of the power-driven, give a cooling wind direction and wind speed requirements, as well as give a few key components of the temperature requirements. Clients when necessary in the design of measuring the temperature of these components, in the most harsh conditions such as the maximum ambient temperature, the minimum lamp voltage, maximum input voltage and other conditions, these key components have been cooled enough, give less than the maximum temperature. Q: What if light should not light up, power-driven high-voltage output of the trigger until it has been switched off the power?
A: If the lamp should not light up, power-driven high-voltage output of the trigger will only exist 1-3 seconds, then switch off its own. Only in the control input once again try to point lighting requirements, the drive power will once again trigger the output of high pressure, will only exist 1-3 per second.

Question: what is the definition of the life of light,
Answer: UHP lamp life is defined as such, a group of samples light were lighted under certain conditions,  when 50% of the effective lamp light output (luminous flux beam or aperture) of not less than 50% of initial value at the time of time to light lamps. In actual use, the lamp life by the application conditions and use of environmental impact.

Q: If lights burst at work, whether it will damage power supply?
A: the basic does not. Power supply with output short-circuit protection, if the lights burst lead after two short-circuit, the drive power to self-protection will not be damaged.

Q: How to adjust the light of (STEP-DIM)? Whether need  adjust the light after light up the bulbs?

Answer: At present, only a portion of drive power with dimming feature, first make sure that the drive power to bring you this feature. Control for dimming control of the optocoupler diode conduction (No. 3 and No. 5-pin pin) can achieve dimming. Please refer to the specific requirements of the specifications book. Dimming control that is at the lights before the lights can also be implemented after lit.

Question: For the DLP color wheel system, it need  the working electricity frequency of bulb and color wheel synchronization, then the general SCI synchronous signal lights light up at how much time after the imposition of?
A: The minimum 100ms, typically 3-5 seconds. Lights lit or not by the control interface FLAG output feedback received.

Ask: the  function of UART embody in what respect?
Answer: UART function is mainly embodied in the benefits:
1. Multipolar dimming
2. Power-driven temperature control and reduce fan noise
3. A product of the projection system applied to different
4. Failure Mode Detection

Question: how to use the UART communication?

A: We are ready on the use of UART communication guiding document - "How to use UART based communications Application Guide." Simultaneously with this document, we have created a computer presentation devices. To allow customers to have a UART communication perceptual awareness.

Q: Under UART mode, when the drive power supply failure, can  it save the fault comfirmation after the turn off the the power supply?

A: Can not. When the drive power failure, if under fault detection mode, the input voltage must be remain higher than the standby voltage (160V).
