Embodiment 1

[0019] Such as Figure 1-3 As shown, an LED light source with integrated intelligent plant characteristic spectrum uniform light provided by Embodiment 1 of the present invention is composed of an LED light source with integrated packaging technology, a multi-channel LED driver chip and an MCU controller. The LED light source emits a spectrum in space Evenly distributed.

[0020] In the first embodiment, the multi-channel LED driver chip is composed of two or more dimmable channels, and a multi-channel LED constant current driver chip that can receive a corresponding port of an external PWM control signal.

[0021] In the first embodiment, the MCU controller is used to receive the data information of the plant characteristic spectrum, and use it as the basis for the light source to emit light, and control the LED light source to emit the required spectrum. The lighting system composed of multiple LED light sources The resulting spectrum is uniform in the space it illuminates....

Embodiment 2

[0033] Such as Figure 4-5 As shown, the second embodiment of the present invention also provides a packaging method for the LED light source that integrates the characteristic spectrum uniformity of intelligent plants as described above, and selects a high-transmittance ceramic (or quartz glass, etc.) cover that cooperates with the substrate 6 plate 1, and three sections are photo-etched on the ceramic (or quartz glass, etc.) 2 and red fluorescent powder 3; a blue chip 5 is fixed on the substrate 6 corresponding to the three intervals, and the ceramic (or quartz glass, etc.) The current of the chip can be adjusted individually.

Abstract

The invention relates to an integrated intelligent plant characteristic spectrum dodging LED light source and a packaging method. The light source adopts an integration packaging technology and blue,white and red LED chips are packaged into one luminescence unit according to different radiation power ratios. Radiation intensity of each type of LED chips can be individually adjusted. Through an intelligent multichannel constant current driving chip and a MCU control circuit, based on a cultivated plant demand, a radiation spectrum is emitted according to a photosynthesis photon flux density (PPFD) corresponding to a characteristic spectrum of a specific cultivated plant so as to carry out illumination according to the characteristic spectrum of the specific plant. The pectrums generated byillumination systems formed by the plurality of LED light sources irradiate the consistent space so that a disadvantage that space distribution of plant characteristic spectrums generated by other modes of light sources is inconsistent is overcome, a luminous energy utilization rate is maximized and benefits can be maximized. In the invention, an ideal illumination device can be provided for scientific research and production of modern agriculture, such as an urban farm, a phytotron, greenhouse seedling and the like.

Description

technical field [0001] The invention relates to an LED light source integrated with intelligent plant characteristic spectrum and uniform light and a packaging method thereof, belonging to the field of agricultural optoelectronic engineering. Background technique [0002] With the advancement of science and technology, the development of modern agriculture, intensive land management and efficient utilization, artificial light sources are playing an increasingly important role, especially LED light sources.
