Led point light source is a light source that is idealized as a particle that emits light in all directions. Led point light sources are abstracted physical concepts in order to simplify the study of physical problems. Just like the smooth plane, the mass point, and the air resistance, the point light source does not exist in reality, and refers to a light source that uniformly emits light from a point to the surrounding space.
LED point light source introduction
LED point light source is a new type of energy-saving and environmental protection decorative lamp. It is mainly used in the decoration of exterior wall of buildings. It is generally low-voltage internal control synchronous colorful control or high-voltage synchronous colorful control and monochrome effect, but through memory control, each point is regarded as Each segment of the digital tube (each point * can be separated by a distance of 3 meters from the signal line) to control can also produce color chasing and scanning water, such as arrayed into a large area bitmap pattern can also produce a variety of advertising text, FLASH pattern, Neon pattern and other effects.
LED point light source is also called bulletproof glass. The base can be aluminum or plastic. It can make the light achieve good results. At the same time, it is cold-resistant, aging-resistant, non-fragile, waterproof, and has no worries when used. The light source has a long service life. Easy to install.
LED point light source classification
The LED point source is divided into two types: a target point source and a free point source.
The target point source can be used to project light to a target point. The distribution properties of the light are isotropic, spotlight, and web.
The function of the free point source is the same as that of the target point source, except that there is no target point, and the user can change the direction of the light by himself. Similarly, the free-point source also has the properties of the above three photometric control light distributions.
Line sources are also divided into two types: target line source (TargetLinear) and free line source (FreeLinear). The target line source can be used to project light to a target object. The distribution properties of the light are diffuse (Diffuse) and mesh (Web). The function of the free line source is the same as the target line source, except that there is no target object, and the user can change the direction of the light by himself.
The same free-line source also has the properties of the above two photometric control light distributions. The diffuse distribution of the light will project light at a certain angle with a large intensity of *, and the intensity of the light decreases as the angle is tilted. The web distribution type allows the user to customize the emission intensity of the light.
Led point source characteristics
1, can be programmed to control multiple synchronization changes, can achieve synchronous colorful, jump, scanning, running water and other full color changes, can also be a plurality of point light source to form a dot matrix screen, change a variety of pictures, text, animation effects, etc. ;
2. It has the characteristics of low power and long life.
3, the pixel is higher, the display accuracy is correspondingly higher, and the close range effect is good. The LED point light source can be controlled by a computer to transmit advertisement information in real time, play an advertisement video, and freely change the advertisement content.
5. Environmentally friendly green lighting. Without mercury filling, it can reduce energy consumption and reduce greenhouse gases and other pollutants emitted into the atmosphere.
Led point light source installation
1. Fix the lamp body to the desired lamp position with screws or glue.
2. Connect the source line and signal line according to the installation drawing and make waterproof treatment.
Precautions:
1. Waterproof when connecting the power cable and signal cable.
2. Note that the power supply is compatible with the operating power of the LED point source.
3. The signal line between the lamp body and the controller is normally connected. The controller's power cord is connected to provide normal operating power.
Application of led point light source
LED point light source is suitable for buildings, amusement parks, large billboards, curtain walls, square streets, stage bars and other places. It is a supplement of linear light source and floodlighting. It has beautiful appearance and can meet the design requirements of the dotted line surface of the building and other decorative objects. It has good waterproof performance, convenient control and convenient installation.
In addition, the LED point light source can be used for the outline of buildings, bridges and other buildings in the dot matrix display and urban lighting projects, and interior lighting projects for entertainment places such as hotels and hotels.
