What is a point light source?

is idealized as a point source of mass. Point light sources are abstracted physical concepts, in order to simplify the study of physical problems.

Point light source is a new type of decorative light, mainly used in building signs, KTV bars and other outdoor embellishments.

Some of the point light sources we can see in daily life

1. Flashlight, flashlight is a very common case of point light source

2. Laser, a device composed by a highly concentrated beam of light. Also belongs to the point light source series of products

3. Stars, when observing stars on the surface of the earth, they become a case of point light sources that show the world of life

4. Light-emitting diodes Light emitting diodes are one of the very common point light sources in life

Characteristics of point light sources

We through the actual verification and summary, came to the following conclusions.

1. point light source of small size and light weight, plus it can be used with many lamps and lanterns, these characteristics are not available in other lamps and lanterns.

2. led point light source has a very good environmental protection. Point light source does not contain the metal mercury, in the waste will not cause mercury pollution. In addition, even if it is abandoned can be recycled, so that both environmental protection and resource saving.

3. led point light source has very good safety and stability. Point light source can be completely in six to twenty-four Ford voltage to DC drive, so both safe and suitable for public places. In addition, under the same conditions relative to traditional light sources, point light source light decay is small and can be used for a long time, can withstand frequent switching.

4. Point light source has a very good seismic shock resistance. The point light source itself using the semiconductor light-emitting principle, its structure is the use of epoxy resin surrounding the lead frame composition. Its composition does not contain glass, not to mention the need to pump it into a vacuum, but also do not need to fill a specific gas. This shows that the point light source has a very good shock and vibration resistance, to the production and transportation and other aspects of the convenience.

5. is a point light source has a very good pointing, it can be directed to send light and direct light to the surface of the object, high utilization. In the LED lighting-related technology continues to research and development process, its luminous efficiency has increased ten times, but this is far from the upper limit.

6. is led point light source has a fast response time. Point light source has a nanosecond response time, much better than the general lighting.

7. is led point light source has a very rich light color, it uses chemical modification as well as monochromatic light mixing and other different means to achieve a variety of colors visible wavelength luminescence as well as the effect of color change. These effects in the decoration and lighting have very good advantages.

Through the above introduction, we can basically cover some good advantageous features of point light source. We can not deny this advantageous feature of point light source, so we also set the goal of continuous research and development it. Like its adjustable brightness, and flicker-free performance, are what we need in the practical application.
