Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0024] Such as figure 1 Shown are graphs of scotopic, photopic, and physiological circadian sensitivity to light spectrum. In addition to the cones and rods, the photoreceptor cells on the retina of the human eye also have a third type of photoreceptor: photoreceptor ganglion cells. This photoreceptor is linked to the biological clock in the human brain, which is caused by the release of melatonin from the pineal gland of the brain. The biological rhythm of normal people coincides with the 24 hours of day and night alternation. With the alternation of day and night, melatonin is secreted and suppressed in large quantities, so that people work during the day and sleep at night. When melatonin in the human body reaches a certain amount, people will feel tired and drowsy. The light received by the human eye will inhibit the secretion of melatonin fr...

Abstract

The invention provides a lamp for improving the work efficiency and the sleep quality of ship crew by using an LED (Light Emitting Diode) light source. The lamp comprises four parts, namely a lamp body (1), a lamp body drive (2), a switch selector (3) and a lamp transparent cover (4). The lamp is characterized in that the lamp body (1) consists of three LED lamps, namely a blue light LED lamp (11) with the wavelength of 425-495 nm, a second blue light LED-excited YAG (Yttrium Aluminum Garnet) fluorescent powder white light LED lamp (12) with the wavelength of 425-495 nm and a red light LED lamp (13) with the wavelength of 625-655 nm, wherein the color temperature of the white light LED lamp (12) is 4000-5000K or 2700-3300K. The invention further provides a method for improving the work efficiency and the sleep quality of the ship crew by using the LED light source.

Description

technical field [0001] The invention belongs to the field of illumination, and in particular relates to a method and a lamp for improving work efficiency and sleep quality of ship crew members by utilizing LED light source illumination. Background technique [0002] Conventional ship lamps only consider the luminous efficiency, illuminance, color temperature, color rendering index, reliability, etc. of the lamps, and do not consider the biological effects of ship lamps on the human body, including improving work efficiency and promoting sleep. For ships, including warships and shipping vessels, the lighting system is a vital part. Because ships sail and work in the ocean for a long time, and a lot of them are carried out at night, even underwater, it will have a significant impact on the safety of the ship, the comfort of the crew, and the psychology and physiology of the crew. The crew of ships spend more than 50% of their time in the operating area, the environment is...
