Two-color temperature lighting device based on laser diode (LD) and preparation method of two-color temperature lighting device

Abstract

The invention relates to the technical field of laser diodes (LD), in particular to a two-color temperature lighting device based on a laser diode (LD) and a preparation method of the two-color temperature lighting device. The two-color temperature lighting device includes a shell, an LD light source and a power supply, the LD light source is electrically connected with the power supply, the two-color temperature lighting device further includes a heat sink, a movable reflective unit and a two-color fluorescence unit, the heat sink is installed at the inner side bottom of the shell, the two-color fluorescent unit is installed at the inner side top of the shell, the LD light source is attached to the heat sink, the movable reflective unit is arranged between the LD light source and the two-color fluorescent unit, and the centers of the heat sink, the LD light source, the movable reflective unit and the two-color fluorescence unit are located at the same center axis. According to the two-color temperature lighting device and the preparation method thereof, the LD light source is used, the size is small, light parallelism is high, the loss of light can be reduced very well, the direction of a laser can be changed by rotating the reflective unit, thus color temperature adjustment is realized, and the using effect is good; and the provided preparation method is simple in process, manufacturing is easy, and the using effect of the manufactured lighting device is good.

Description

technical field [0001] The invention relates to the technical field of LD, in particular to an LD-based two-color temperature lighting device and a preparation method thereof. Background technique [0002] Since the invention of the world's first LD in 1962, LD has undergone tremendous changes, greatly promoting the development of other science and technology, and is considered to be one of the greatest human inventions in the 20th century. In the past ten years, the development of LD has More rapidly, it has become the fastest growing laser technology in the world. The application of LD covers the entire field of optoelectronics and has become the core technology of today's optoelectronics. LD is characterized by small size, light weight, good reliability, long service life, The advantages of low power consumption and low cost make it widely used at present. As a potential light source, it is highly valued. In addition, the semiconductor laser adopts a low-voltage constant-...

AI Technical Summary

Problems solved by technology

[0004] In some special lighting occasions, such as shopping malls, counters, coffee shops and other places, it is necessary to use two-color temperature lights to meet the needs, but the existing LD lighting devices cannot realize the function of dimming and color adjustment, and cannot better meet the needs of people with two-color lighting. Use in places where temperature is required
