LED point light source is a new type of energy-saving and environmental protection decorative light, using LED cold light source luminescence, built-in microcomputer chip, can be arbitrary programming control, multiple synchronous change, monochrome change can also achieve synchronous color gradient, jump, scanning, full color change effect of water lamp and multiple LED point light source composition lattice screen.Can be changed to a variety of pictures, text and animation effects, is a linear light source and floodlight lighting a supplement, beautiful appearance can meet the building and other decorative point line surface design requirements.LED point light source USES aluminum base, heat dissipation, excellent waterproof performance, easy installation, simple control, low voltage power supply, safe and reliable, noble appearance, is the building, bridge outline, hotel, billboards, curtain wall and night lighting ideal decoration.
(1) small size
Compared with traditional light source, LED light source is small in size and light in weight, and can be made into devices of various shapes, which is convenient for the layout and design of various lamps and equipment. It has strong adaptability and wide application range.
(2) good environmental performance
As the LED light source does not need to add metal mercury in the production process, the LED will not cause mercury pollution after being discarded, and the waste can be almost completely recycled, which not only saves resources, but also protects the environment.
(3) safety and stability
LED light source can be driven by low-voltage direct current, and the general supply voltage is between 6 and 24V, so the safety performance is better, especially suitable for public places.In addition, under better conditions of the external environment, LED light source has smaller light decline and longer life than traditional light source. Even frequent switching does not affect its service life.
(4) good seismic and impact resistance
The basic structure of the LED light source is a piece of electroluminescent semiconductor material, placed on a shelf with a lead, and then sealed around with epoxy resin. There is no glass shell on the structure, and it does not need to be vacuumed or charged into a specific gas in the tube like incandescent or fluorescent lamps.Therefore, LED light source has good seismic and impact resistance performance, which brings convenience to its production, transportation and use.
(5) strong directivity
Compared with traditional light sources, LED light sources emit directional light, most of the light from the LED can be directly directed to the surface, the utilization rate is far higher than traditional light sources.
(6) fast response time
The response time of incandescent lamp is millisecond, and that of LED light source is nanosecond.Therefore, it is widely used in the field of traffic signal and automobile signal light.
(7) high luminous efficiency
With the development of LED lighting technology, the luminous efficiency of LED light source has been improved from less than 10lm/W to more than 100lm/W, and its luminous efficiency still has great potential to be improved.
(8) rich light and color
By changing current, chemical modification, monochromatic light mixing and other methods, LED light source can achieve light emission and color change of various colors in visible light band. Even for white LED, it can also be made into light source of various color temperatures.Therefore, in the interior decoration illumination and the landscape illumination has the obvious superiority.
(9) no flicker, no uv
The LED light source USES dc power supply, with stable and non-flicker luminescence, and the spectrum is mainly concentrated in the visible region, and there is basically no interference of ultraviolet or infrared radiation, so as to avoid the adverse effect of stroboscopic effect and improve the human eye comfort.
(10) good brightness adjustment
According to the luminescence principle of LED light source, the luminance or output flux of LED basically changes in a positive direction with the current.And its working current can be large or small in the rated range, with good adjustable, for the LED light source to achieve on-demand lighting, brightness stepless control laid the foundation.
It is precisely because the LED light source has the advantages that the above traditional light source cannot match that the LED light source has become the focus and direction of the development of the lighting industry in various countries.
