Problems solved by technology

However, the performance of LED is very complicated, the product types are rich and diverse, and new technologies emerge in an endless stream. These standards and specifications are far from meeting the needs of the development of lighting LED products. Therefore, many domestic institutions are still carrying out research on testing standards for lighting LEDs. 1. Most organizations lack testing experience, so the consideration when formulating test method standards is relatively one-sided, and it causes a lot of repetitive wasteful work

Embodiment 1

[0052] Example 1 A detection method for LED photobiological safety

[0053] 1. Preliminary preparation: prepare the light source, bracket, computer and related software.

[0054] light source

[0055] We packaged three red, green and blue chips and one IC chip in a hemispherical lampshade assembly with a radius of 18 cm. The IC chip controls the working current of the three chips, and the light intensity of the three primary colors changes with the current, so that the color of the mixed light emitted changes accordingly. The chip of the light source can be replaced, thereby changing the parameters of the LED lamp. The lampshade is made of non-magnetic aluminum. The transformer of the LED is connected to the lamp with wires. The wire between the transformer and the lamp exceeds 5 meters, so that the transformer can be placed outside the magnetic resonance room to prevent the transformer from being attracted by the magnetic resonance field and avoid the transformer ...

Abstract

The invention discloses a biological safety detection method for LED (light-emitting diode) light, which belongs to the illuminating engineering field, and specifically relates to a safety detection method of a light source, in particular to the safety detection method of an LED light source. In order to better detect the biological safety of the LED light, the invention provides a novel biological safety detection method for the LED light; in the prior art, detecting the extent of the damage on retina is currently mainly used as a method for measuring the biological safety of the LED light. The inventor of the invention provides a new way, introduces a functional magnetic resonance imaging technology and analyzes the cerebral function by the functional magnetic resonance imaging to evaluate the biological safety of the LED light; the detection method is objective and belongs to a noninvasive test method; the change of a BOLD-fMRI (blood oxygenation level dependent-functional magnetic resonance imaging) signal caused by the change of the brain blood flow when the human eye is stimulated by different light sources is changes before the retina change obtained by various inspection methods. Therefore, using the fMRI to evaluate the biological safety of the LED light is feasible.

Description

technical field [0001] The invention belongs to the field of lighting engineering, and in particular relates to a safety detection method of a light source, in particular to a safety detection method of an LED light source, especially a biological safety detection method of the LED light. Background technique [0002] With the looming energy crisis and the increasing awareness of energy saving, environmental protection and low carbon, the global market prospect of new LED (light emitting diodes, light emitting diodes) lighting sources is brighter. LED lighting, as a strategic emerging industry for energy conservation and environmental protection, is gradually receiving great attention from the state and local governments at all levels. With the advancement and development of technology, the LED lighting industry will surely become a new growth point for the green energy-saving industry. Stimulated by market interest trends and laws and regulations, the scale of the global LE...
