The newly developed technology in recent years has low heat generation and is called cold light source.
Due to the small size of the light-emitting parts and the small size of the heat dissipation system, this type of projector is small and portable. Its advantage is that it has a long service life, reaching 2W-5W hours, energy saving and environmental protection, and the size of the projector can be made very small, and it can be used in all handheld devices in daily use, so it is quickly accepted and loved by consumers , LED light source is booming in projector light source technology, and the technical level and sales volume are rising every year, which is the future development trend.
