Laser street lamp system

Abstract

The invention discloses a laser street lamp system. The system comprises an optical module and an electrical module; the optical module comprises ultra clear glass and one or multiple blue light LD lighting modules; each blue light LD lighting module comprises a blue light LD light source, a fluorescent substance bearing table, a shaping module and a reflecting bowl, wherein the fluorescent substance bearing table corresponds to the blue light LD light source, fluorescent substances are arranged at the face, opposite to the blue light LD light source, of the fluorescent substance bearing table, a shaping lens is arranged on the shaping module, and is used for shaping light emitted by the blue light LD light source to be in a reserved shape, and therefore the light passing through the shaping lens is completely irradiated on the fluorescent substances, and the reflecting bowl is used for jointly reflecting lighting light rays excited by the fluorescent substances and light which is irradiated on the fluorescent substance and is not excited out of a bowl opening of the reflecting bowl; the electrical module is divided into four paths, and the four paths are in parallel connection to supply power to the optical module; and the electrical module is connected with the blue light LD lighting modules through a circuit board. The system has the following beneficial effects of being high in illuminating brightness, good in directivity, far in irradiating distance, extremely low in energy consumption, high in efficiency, good in controllability and free of any harm to eyes of human.

Description

technical field [0001] The invention relates to the lighting field, and specifically designs a laser street lamp system. Background technique [0002] On December 8, 2014, Nobel Prize winner Nakamura Shuji pointed out in his Nobel Prize commemorative speech at Stockholm University in Sweden that semiconductor laser lighting is the development direction of future lighting. Because blue LEDs have the problem of "decreasing light efficiency", the higher the brightness, the more difficult it is to improve efficiency. Laser lighting does not have this problem, and laser lighting has the advantages of high brightness, good directionality, long irradiation distance, extremely low energy consumption, high efficiency, good controllability, and no harm to human eyes. Therefore, Shuji Nakamura predicts that laser lighting will replace LED lighting in the future. It can be predicted that with the continuous maturity of technology, the cost will continue to decrease. In the near future...
