Different Light Sources and How to Choose a Laser Projector Wisely?

Updated: Jul 19, 2022

At present, there are three types of light sources for laser projectors on the market, which are true three primary laser, dual laser, and the most ordinary monochromatic laser. According to the comparison of color rendering effect( effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference or standard illuminant), the effect from best to bad is three primary laser > dual laser > monochromatic laser.

Monochromatic laser generally uses blue laser as a light source, which is the most inexpensive way. What about dual laser? Most of the dual laser from the laser phosphor projector relies on blue laser light, filtering a laser or using hybrid laser technology as it lacks red and green. It’s normally from modestly priced to a high price as many companies position themselves as “high end”. They are commonly available to consumers. As compared, the ideal system used three primary lasers (red, green, and blue) are much more expensive than the two mentioned before due to the cost. It's more commonly used in the cinema market. With a professional background in laser cinema projectors, CASIRIS is devoted to bringing customers a real home theater feast at an affordable price.

Monochromatic laser projector has low brightness, which appears gray in projection and color becomes dull under strong ambient light or during daytime. Both the monochromatic laser projector and laser phosphor projector are far weaker than three primary laser in the adaptability of environment light. In addition, the lifetime for most monochromatic laser projectors and laser phosphor projectors is less than 30,000 hours.

CASIRIS true three primary laser projector is powered by three primary lasers system (just RGB lasers and not hybrid) to individually generate output light and a spectrum of colors. The luminous efficacy is far higher than other laser sources we mention above (luminous efficacy is a measure of how well a light source produces visible light): the electric excitation directly generates true laser, and up to 98% is used in projection light. At the same time, there is less waste heat. As compared, the luminous efficacy for projection of a blue light laser phosphor projector is only 35%.

As a result, you will get striking visuals with vivid color and high brightness from a three primary laser projector. True three primary laser can restore 70% of the color, while the LCD TV could only restore 40%. With its affordable price and high performance for the true three primary laser projectors, it will become mainstream in the next generation of the projection industry.
