What Are the Advantages of Led Light Source in Lighting!

Outdoor Lighting Application

As a new generation of light sources, led light sources are very different from traditional heat radiation and gas discharge light sources such as incandescent lamps and high-pressure sodium lamps. The current led light sources have the following advantages in lighting:

1. Small Volume:

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

2. Good Environmental Performance:

Since 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 almost all of its waste can be recycled, which not only saves resources, but also protects the environment.

3. Safe and Stable:

The LED light source can be driven by low-voltage direct current, and the general power supply voltage is between 6~24V, so the safety performance is better, especially suitable for public places. In addition, under the condition of good external environment, LED light source has less light decay and longer life than traditional light source. Even if it is switched frequently, its service life will not be affected.

4. Good Shock and Impact Resistance:

The basic structure of the LED light source is a piece of electroluminescent semiconductor material, which is placed on a leaded shelf, and then sealed with epoxy resin around it. There is no glass shell in the structure, and it does not need to be in the lamp tube like incandescent or fluorescent lamps. It is evacuated or injected with a specific gas. Therefore, the LED light source has good shock resistance and shock resistance, which brings convenience to its production, transportation and use.

5. Strong Directivity:

Compared with the traditional light source, the light emitted by the LED light source is directional, most of the light emitted from the LED can be directed to the illuminated surface, and the utilization rate is much higher than that of the traditional light source.

6. Fast Response Time:

The response time of incandescent lamps is in milliseconds, and the response time of LED light sources is in nanoseconds. Therefore, it is widely used in the fields of traffic signals and car lights.

7. High Luminous Efficiency:

With the development of LED lighting technology, the luminous efficiency of LED light source has been increased from less than 10lm/W to more than 100lm/W, and its luminous efficiency still has the potential to be greatly improved.

8. Rich Colors:

The LED light source can realize the luminescence and discoloration of various colors in the visible light band by changing the current, chemical modification, monochromatic light mixing, etc. Even for white LEDs, it can be made into a light source with various color temperatures. Therefore, it has obvious advantages in interior decoration lighting and landscape lighting.

9. Flicker-free, UV-free:

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

10. Good Brightness Adjustability:

According to the light-emitting principle of the LED light source, the LED light-emitting brightness or output luminous flux basically changes positively with the current. Its working current can be large or small within the rated range, and has good adjustability, which lays the foundation for the LED light source to achieve on-demand lighting and stepless brightness control.

It is precisely because the LED point light source has the incomparable advantages of the above traditional light sources that the LED light source has become the focus and direction of the development of the lighting industry in various countries.
