Illuminates UHP (Ultra High Performance) by PHILIPS which develops regarding the projected display market is a big contribution. Because unceasingly develops the product the multiplication, PHILIPS continuously holds it in the ultrahigh voltage mercury vapor lamp domain leading status. Also because we provide widely, most innovates the product, enables our partner unceasing to promote brightly, a stabler design in the market. so, nowadays project display equipment, no matter is applies specialty front project the large screen display wall, the video and music family theater, the back project the display wall, carries the projection television perhaps in the television wall equipment domain, the PHILIPS UHP system has become the field unification the standard.
PHILIPS illuminates in the 1990s inaugurates sends out UHP (Ultra High Power) the photosource, has brought the revolutionary breakthrough for the projection photosource, the many kinds of specifications (including 100W/120W/132W/150W/200W/250W and so on) coordinate parabolic or the ellipse spherical surface reflection cup front, can satisfy the projector, the back project, the television wall, the project wall, the splicing wall, the display system and so on large screen display wall system each kind of application. This kind of photosource has the following characteristic:
(1) The average brightness reaches as high as 1Gcd/m2, the electric arc spacing is 1.0/1.3/1.45mm, the short spacing electrode can apply to the light-sized chip kneading board.
(2) UHP has the longest service life, uses in the back to project the demonstration domain photosource life to be possible to amount to for 6000-15000 housr front, uses in to project the domain photosource life to be possible to amount to for 1000-6000 hours.
(3) Maintains the electric arc through the belt pulsation actuation power source stably to shine, can the effective stable electrode borrow the occurrence which this suppression glitters to eliminate large screen to glitter.
(4) The extremely stable color spectrum performance and the superior light pass the maintenance rate. Service life period, UHP has stably, most perfect chromatograph PHILIPS illuminates during maintenance ultrahigh voltage mercury lamp domain leading status, unceasingly improves the design craft, the promotion product quality and the reliability, had the recent development in the UHP projection photosource display wall system technical change aspect.
The UHP ordinary home use large screen back project the display wall system, is very high to the projection photosource life request. At present, the PHILIPS back project the 100W photosource life to enhance from 10,000 hours to 15,000 hours, soon hopefully enhances to 20,000 hours.
The lamp request has the good hot start performance, before only can through actuate the power source to provide the extremely high start peak voltage (about 20kV) to realize, now developed has then realized the fast hot start lamp under the 5kV condition. This lamp in the discharge tube the conformity small cavity body, with the aid of the auxiliary antenna, started when the lamp could have the few ultraviolet rays, thus greatly reduced the breakdown voltage which the discharge tube needed.
In order to adapt the projector market miniaturization tendency, PHILIPS has developed E17 small reflection cup lamp -Bami, this lamp end surface size only has 33mmx 33mm, the counter- refacing is the ellipse spherical surface, a discharge tube spheroid side plates the reflection membrane, the light is reflected the reflection cup, greatly enhanced luminous flux. This technology and the monolithic DLP technology unify, potential extremely exquisite portable projector.
The surge of current, is PHILIPS's patent technology, namely produces the surge of current before the lamp electric current commutation, this kind of technology solved well has generally projector lamp because the electric arc did not stabilize causes the large screen scintillation. This system effectively applies to the LCD projector, afterwards successfully applies to in a monolithic DLP projector six sections of colors turn of system, the pulse sets between two colors sections, designs the pulse and the color frequency 1:1, avoids pulse frequency Gao eitherguo lowering affects the light bulb life or cannot truly prevent glitters.
