Problems solved by technology
The color light produced by this method generally has a wide spectral range, and the color is not pure, so it is not bright enough
In addition, the beam generated by the existing method is an expanded beam, and the light energy is scattered and difficult to control

Embodiment Construction
[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Such as figure 1 As shown, the semiconductor light-emitting device 101 adopts semiconductor light-emitting diodes, which include three light-emitting chips of red, green and blue, which can respectively generate light with central wavelengths of 625nm, 520nm and 470nm, and the power of each chip is 0.5W. The currents of the three light-emitting chips can be controlled separately, and colored light of different colors can be synthesized. Transparent tank 105 is made of plexiglass. The focusing lens 102 is made of optical glass, and its focal length is 10 mm. The water outlet 106 is circular with a diameter of 5 mm. Both the intake solenoid valve 110 and the water intake solenoid valve 114 are DC control solenoid valves with a control voltage of 6V.
[0018] When the water inlet solenoid valve 114 is opened, the water flow enter...

The invention relates to a semiconductor lighting device water current optical waveguide decorative lighting device and a lighting method thereof. The lighting device comprises a lighting trough, a water intake pipe, a semiconductor luminous device, a focusing lens, an air feeding pipe and an electromagnetic valve. The decorative lighting method comprises following steps: a light beam emitted by the semiconductor luminous device is focused by the focusing lens to the water current in the transparent trough water outlet, stable water current is varied by controlling water intake or air intake,thereby twinkling feeling of the water current is provided by the water current optical waveguide, straight line, circular or wave water current optical waveguide is obtained by controlling water current parabolic ejecting angle, and steam current optical waveguide of an area array or a 3D array is obtained by assembling a plurality of devices. Whether the water current irradiates or not and irradiating positions are controlled by controlling water flow and whether adding air bubbles into the water current or not, so that verified effective control can be performed to water irradiation, and colorful and dynamic decorative effect is implemented.
Description
technical field [0001] The invention relates to an illuminating device and an illuminating method for water flow optical waveguide decoration of a semiconductor light-emitting device, belonging to the field of optical waveguide and decorative illumination. Background technique [0002] Water flow has been used in many indoor and outdoor landscapes. The flowing water adds movement and vitality to the still scenery, increasing the beauty of the environment. Now, various indoor and outdoor fountains and artificial waterfalls can be seen everywhere. Project lights of different colors on the water flow to form colorful fountains or waterfalls. The colorful colors are reflected, refracted or scattered by the water flow, forming a fascinating scene, which adds interest to the landscaping environment and people's lives. At present, the method of adding common light and color filter is widely used to generate colored light and project it on the water flow outside the water flow. ...
