Led Point Light Source

- Nov 29, 2018-

As a new generation of light source, LED light source is quite different from traditional heat radiation and gas discharge light sources such as incandescent lamps and high pressure sodium lamps. The current LED light source has the following advantages in lighting:

(1) small size

Compared with the traditional light source, the LED light source is small in size and light in weight, and can be fabricated into various shapes of devices, which is convenient for arrangement and design of various lamps and equipments, has strong adaptability and wide application range.

(2) Good environmental performance

Since the LED light source does not need to add metallic 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) Safe and stable

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

(4) Good seismic and impact resistance

The basic structure of the LED light source is an electroluminescent semiconductor material placed on a leaded shelf and then sealed with epoxy resin. There is no glass casing on the structure, and it does not need to be inside the lamp like incandescent or fluorescent lamps. Drain or rush into a specific gas. Therefore, the 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 the LED light source is oriented, and most of the light emitted from the LED can be directly directed to the illuminated surface, and the utilization rate is much higher than that of the conventional light source.

(6) Fast response time

The incandescent lamp has a response time of milliseconds and the LED light source has a response time of nanoseconds. Therefore, it is widely used in the field of traffic signals and car signal 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 10 lm/W to more than 100 lm/W, and its luminous efficiency still has a great potential for improvement.

(8) rich in light color

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

(9) No flicker, no UV

The LED light source adopts 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 of ultraviolet rays or infrared radiation, thereby avoiding the adverse effects caused by the stroboscopic effect and improving the comfort of the human eye.

(10) Brightness is adjustable

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

It is precisely because LED light source has the advantages that the above traditional light source can't match, so LED light source has become the focus and direction of the development of lighting industry in various countries. Traditional light source.
