Characteristics of LED point source light

2022-12-19

As a new generation of light source, LED Point Source Light is very different from traditional thermal radiation and gas discharge light sources such as incandescent lamp and high-pressure sodium lamp.

The current LED light source has the following advantages in terms of lighting:

1.Small size

Compared with traditional light sources, LED light sources are small in size and light in weight. They can be made into devices of various shapes, which is convenient for the layout and design of various lamps and equipment. They have strong adaptability and wide application scope.

2.Good environmental performance

As the LED Point Light does not need to add metal mercury in the production process, it will not cause mercury pollution after LED is discarded, and almost all of its waste can be recycled, which not only saves resources, but also protects the environment.

3.Safe and stable

LED light source can be driven by low-voltage DC, and the general power supply voltage is 6~24V, so the safety performance is good, especially suitable for public places. In addition, under good external conditions, LED light source has smaller light attenuation and longer service life than traditional light source. Even if it is switched frequently, its service life will not be affected.

4.Good seismic and impact resistance

The basic structure of LED light source is a piece of electroluminescent semiconductor material, which is placed on a shelf with leads, and then sealed with epoxy resin around. There is no glass shell in the structure, so it is not necessary to pump vacuum or rush specific gas into the lamp tube like incandescent lamp or fluorescent lamp. Therefore, LED light source has good seismic and impact resistance, which brings convenience to its production, transportation and use.

5.Strong directivity
Compared with the traditional light source, the light emitted by LED light source is directional. Most of the light emitted from LED can directly reach the illuminated surface, and the utilization rate is far higher than that of the traditional light source.

6.Fast response time
The response time of incandescent lamp is milliseconds, while that of LED light source is nanoseconds. Therefore, it is widely used in the field of traffic signal and automobile signal lamp.

7.High luminous efficiency
With the development of LED lighting technology, the luminous efficiency of LED Point Light has been improved from less than 10lm/W to more than 100lm/W, and its luminous efficiency still has great potential for improvement.

8.Rich light and color
LED light source can realize light emission and color change of various colors in visible light band by changing current, chemical modification, monochrome mixing and other methods. Even for white LED, it can also be made into light source of various color temperatures. Therefore, it has obvious advantages in interior decoration lighting and landscape lighting.

9.No flicker, no ultraviolet light
The LED light source uses DC power supply, and its light emission is stable and does not flicker. The spectrum is mainly concentrated in the visible light area, and there is basically no interference from ultraviolet or infrared radiation, which can avoid the adverse effects of stroboscopic effect and improve the comfort of human eyes.

10.Good brightness adjustability
According to the luminous principle of LED light source, the luminous brightness or output luminous flux of LED basically changes in a positive direction with the current. Its working current can be large or small within the rated range, and it has good adjustability, which lays a foundation for LED light source to achieve on-demand lighting and infinite brightness control.

It is precisely because LED point light source has the advantages that traditional light sources cannot match, so LED light source has become the focus and direction of lighting development in various countries.
