Problems solved by technology

[0007] However, the method of adding a heat sink to the lighting device will lead to a substantial increase in the weight of the device and a rise in the cost of the device
In addition, the addition of the current limiting circuit shown in the above-mentioned prior patent documents complicates the control circuit of the lighting device, and the increase in the cost of the device and the increase in failure factors due to the increase in the use of electronic components Defects caused
In particular, among the above-mentioned lighting devices for indoor cultivation facilities, the use of an extremely large number of light-emitting diodes for one lighting device is regarded as a fatal flaw in the popularization of lighting devices.

Abstract

The invention discloses an LED lighting device. The lighting device includes a transparent box, a PCB arranged in the transparent box, and a plurality of LEDs arranged on the PCB in a laying manner. The LEDs are connected through circuits. The driving current adopted by the LEDs is in a range of 55% to 85% of a rated current of the LEDs. The installation density of the LEDs on the PCB is 1.0 to 1.5 per cm2. In the invention, the driving current of the LEDs is reduced. By increasing the number of the LEDs assembled on the lighting device, the integral luminance of the lighting device is kept. The heating volume generated on the lighting device is reduced. And the service lifetime of the LEDs used on the lighting device is prolonged. Besides, the economical efficiency of the LED lighting device used in indoor cultivation facility is also improved.

Description

technical field [0001] The invention relates to an illuminating device with light-emitting diodes laid on a printed circuit board, in particular to a light-emitting diode illuminating device for indoor cultivation of plants and the like. Background technique [0002] At present, with the rapid development of semiconductor technology in the past few years, the characteristics and efficiency of light-emitting diodes have been exceptionally improved. Diode lighting devices have replaced the previous incandescent lamps and fluorescent lamps and are gradually widely popularized in society. [0003] Furthermore, lighting devices using light-emitting diodes are widely used in various fields other than lighting in general homes and offices. In particular, the use of light-emitting diodes for artificial lighting called "plant factories" and the use of cultivation facilities that grow a large number of plants and vegetables indoors have attracted widespread attention. This is becaus...
