Projector with the working time of growth, the brightness effect will gradually decrease until the last picture blurred. Are we in any way to make the projector always maintain high brightness projection effect? the answer is Yes, we just do the following: the five mentioned as possible, we will be able to enjoy for a long time to highlight the drop shadow effect!


Try to choose the right environment

Projector in the work process, its eventual projection brightness effect will be affected by the ambient light effects, this is because the human eye can feel the effect of projection brightness is determined by the projector itself working ambient light emitted by the projection of light with the role. For example, if the projector is very strong environmental light, 2000 lumens projector bulb function to display the on-screen brightness effect, most likely with 1500 lumens projector bulb effect of brightness on the screen almost the same effect, this is because the display screen on the external lights is very strong, will launch on the projection lamp to the screen of a high degree of light reflection, so the display screen from the projector in real light energy will be significantly reduced, so the human eye can feel the screen brightness, of course, it will decline. In order to highlight the drop shadow effect, we must pay attention to the selection of projection environment, ensure that the projector to work outside the light interference weaker projection environment, such as suitable projection environment screen, floors, walls, curtains, etc., must maintain surface roughness, rather than pursuit of clean bright, smooth. If find projection environment with strong light interference, must try to use dark curtains or other shelter from the outside light blocking or direct light in a work environment due to close some so that the ambient light on the extent of projection of the light to minimize interference.

Minimize screen size

When we say "screen size", in fact, the projector lamp is projected onto the display screen on the display screen's size. Normally, the projection lamp light energy projections out to the same case, the display area of the smaller, then the screen area for light energy is higher, then the area of the screen brightness effect will be better; on the contrary, the larger the size of the display, then the screen area for light energy is smaller, then the area of the screen brightness effect becomes poor. For example, if in 2500 lumens projector lamps, projection light emission to 120 inch display on the screen when the brightness effect to be better than projected light emission to the 150-inch display on the screen when the brightness effect to be high, after all, in the same light source energy, a projection screen display area larger, so the total light energy is large display screen "partition", the more powerful, flat display screen absorption into the light energy will be smaller, the human eye can feel the brightness effect also becomes poor. Therefore, in projection light energy is not large, the projection screen of the display area of the control is a smaller, often can be relatively good brightness effect.

Try to control the duration of the

Here refers to the "duration", in fact, every time the projector is turned on, the maximum number of hours could be sustained projection. Considering the projector in a long time projection process, its interior will have a high heat generated, these heat accumulated to a certain extent will make projector internal operating temperature rises quickly; and the work environment at a high temperature, projector internal many optical devices easier to produce lost through phenomenon, the phenomena are particularly vulnerable to the optical lens surface produce spots, and the number of spots with projectors work time while gradually increased. Once the optical lens surface is too many spots on the cover, then the projection of the light emitted by the bulb will be obvious "irresistible", so easy to get the projection screen of effective light source energy reduction, thus causing the display's brightness effect reduced. Therefore, in order to highlight the drop shadow effect, we try to control the projector's time continuing work to ensure that every projection projectors working hours must not exceed four hours.

Try to set a high resolution

Now many projector products, projection can allow users to set the output resolution, different size of the output resolution, you can ensure that the projection screen for different projection display effect.

In General, the projection lamp energy exactly the same conditions, the projector's resolution is set higher, so people feel out of projection display effect would be better, but the projector's resolution is set lower, eyes feeling out of projection display effect becomes poor. According to this theory, it is not difficult to find in the projector itself brightness lower cases, to obtain good projection demo effects, must try to projector output resolution is set high.

To minimize casting spacing

Here's the "projection space" refers to the display screen and projector placement distance between. Normally, the greater the projection space, then the projection lamp emitting from the projection of light in the air transport have distance will further projection light energy attenuation range will be displayed on the screen larger real effective light less, eyes feel the drop shadow effect will be less, while the smaller the projection space, then the projection lamp emitting from the projection of light in the air transport had to distance the more short projection light energy attenuation rate will lower the display screen really get effective light would have, the more the human eye can feel the drop shadow effect will be better. Therefore, to minimize casting distance, is also a drop shadow effect to highlight one of the effective ways.
