Laser pointer and LED power
Therefore, you'd better have a good laser demonstrator to help you make a perfect presentation. Laser Pointers can help you get things done quickly, and this pen-like device can not only help you win a contract, but also help keep your pet in a good mood. Having pets in your home is not a big deal, but it's vital to keep them busy and play with them so they don't get upset and start destroying things in your home. The solution is to use a green laser pointer. The Green laser pointer is the most powerful 532nm portable laser in the world. The infrared laser pointer's remote beam visibility provides the ability to write wonderful experiences. It is a high-performance laser used to burn games, cigarettes, plastics and more. This is FDA's perfectly legal laser approval for each case, non-commercial use. Ambient light level. If you're stargazing at dusk, during a full moon, or in a built-up area with a lot of light pollution, it's hard to see low-power beams like 5mW. In this case, you typically need at least 50 mW or more.

Application
Higher-power laser Pointers aren't always better, as their glare can easily ruin your night vision and can be distracting. Several nights of stargazing were ruined when more attention was paid to the fancy new high-power lasers used to point at objects than to the objects themselves. Because of the small divergence Angle of the 500mW high powered laser, the phosphor stimulated by laser is smaller than the LED point and easier to group. In the early application of projection, gas lamps, mercury lamps and other light sources were selected. These lamps were widely distributed, and it was necessary to combine several complex optical systems to achieve projection, which would lead to the passing of a large number of optical systems in the later period. As a result, the light source is only about 3% efficient. Existing leds can convert efficiency to 30-40%, and if lasers are used as a light source, efficiency can be increased to more than 60%. Lasers and LEDS work in a similar way: they use a blue light source (lasers can also use ultraviolet light) to excite phosphors to produce yellow light, which is then mixed to produce white light. Compared to LED lighting, laser lighting is more efficient, brighter and more flexible than LED lighting.
