Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a lighting system. Background Art

[0002] Generally, the maximum driving current and power of lighting equipment such as lamps are set before leaving the factory. However, after the LED light-emitting diodes work for a long time, the luminous efficiency will decrease, thereby causing the overall lumen output of the lamp to decrease.

[0003] Lumen is a unit of luminous flux, which indicates the total amount of visible light emitted by a light source. The higher the lumen, the brighter the light source. Lamp lumen refers to the total amount of visible light emitted by a lamp, that is, the brightness of the lamp. Lamp lumen is related to factors such as the lamp power, efficiency, and light color. Generally speaking, the higher the power, the higher the lumen of the lamp, but the efficiency of the lamp should also be considered, that is, how many lumens of light can be emitted for every watt of electrical energy consumed. The higher the efficiency, the higher the lumen of the lamp. In addition, lamps of different light colors will have different lumen values ​​even if the power and efficiency are the same, because the human eye has different sensitivities to different wavelengths of light. Generally speaking, the lumens of lamps with neutral white light and cool white light will be higher than those of lamps with warm white light.

[0004] Lumens are an important indicator of the brightness of lamps, but they are not the only indicator. When choosing lamps, other factors should also be considered, such as illumination, color rendering, color temperature, and lifespan. Illuminance refers to the luminous flux density of a light source shining on a surface, and the unit is lux. The higher the illumination, the brighter the surface. Color rendering refers to the ability of a lamp to restore the color of an object, which is expressed by the color rendering index. The higher the color rendering index, the more realistic the color of the object. Color temperature refers to the degree of similarity between the color of the light emitted by the lamp and a certain point on the blackbody radiation curve, and the unit is Kelvin. The higher the color temperature, the colder the light color. Lifespan refers to the time that a lamp can continue to work under normal use conditions, and the unit is hours. The longer the lifespan, the more durable the lamp.

[0005] In summary, the lumen of a lamp refers to the total amount of visible light emitted by the lamp, that is, the brightness of the lamp. When choosing a lamp, you should consider various factors according to your needs and preferences and choose the right lamp. According to the GB / T50034 architectural design lighting standard, there are clear requirements for the illumination of different scenes. Since lamps have longevity properties, current LED lamps cannot replace LED light-emitting components like replacing light bulbs before. This will cause many families to use LED lamps for many years. The LED light decay causes the overall illumination of the lamp to decrease, and the illumination cannot reach the standard, causing a series of eye problems.

[0006] In addition to LED light decay, another factor that affects the illumination of lamps is the light cover. Most light covers are made of plastic materials such as PC and acrylic. After long-term use, they will turn yellow and deform, affecting the final lighting effect of the lamp. In addition, due to the different installation locations of lamps in the home and the different lengths of use, the degree of light attenuation is also inconsistent. For example, for lamps installed in the kitchen, the surface light cover will age faster due to long-term exposure to oil stains. For example, for lamps installed on the balcony, the surface light cover will age faster than indoor lamps due to the influence of ultraviolet rays in outdoor sunlight, and the light transmission effect will deteriorate, which will ultimately affect the illumination output of the lamp.

[0007] Some lighting products on the market achieve light decay compensation by controlling the current of the driver to adjust the output light intensity. However, this solution only targets the light decay of LED lamp beads, and the solution is single and cannot be used for lamps in different environments. The effect of light decay compensation is somewhat limited. Utility Model Content

[0034] The implementation of the embodiment of the utility model will have the following beneficial effects: when the lighting system 100 of the present solution is powered on, the driver 40 is responsible for converting the mains power into low-voltage power supply to supply power to the controller 50; under the control of the controller 50, the lighting fixture 20 provides lighting at a preset illumination value, and the photosensitive component 30 senses the ambient illumination value in real time; the photosensitive component 30 transmits the real-time illumination value to the controller 50, and the controller 50 compares the received real-time illumination value with the preset illumination value; when the real-time illumination value is greater than or equal to the preset illumination value, the controller 50 maintains the current of the current to the lighting fixture 20. , so that the lighting fixture 20 maintains a preset illumination value to provide lighting; when the real-time illumination value is greater than the preset illumination value, the controller 50 increases the current output to the lighting fixture 20 to enhance the light intensity of the lighting fixture 20; in this way, no matter how long the lighting system 100 is used or what material it is made of, it can flexibly adjust the illumination value of the lighting fixture 20 in real time according to the illumination value of the current environment (i.e., different environments), thereby improving the light intensity of the lighting fixture 20 after light decay occurs, always ensuring that the lighting fixture 20 maintains the best lighting effect and preventing damage to the user's eyesight.
