LED shopping mall lighting needs and design points
Today, shopping mall lighting is considered to be one of the most mature and rapid fields of LED application. The shopping mall is not only a place to buy items, but also to create an environment suitable for leisure. The lighting effect is indeed indispensable. LED lighting has a strong advantage in expressiveness. But whether LED can play a greater role in the shopping mall lighting market needs to be based on the specific lighting environment and the humanized needs of consumers, and refine the various performance parameters and lighting effects of each product.
Shopping mall lighting design is the behavior of customers to purchase products. In the process of browsing and selection, according to the visual requirements of customers, the characteristics of various products, and the space where each product is located, scientific design is carried out to make customers feel comfortable. visual effect.
At the same time, reasonable illuminance (commonly known as brightness), good color reproduction, suitable brightness distribution, and a comfortable visual environment; through reasonable lighting design, customers can be attracted to the goods and create a comfortable shopping environment. , to stimulate customers' desire to buy.
1. Illumination and color temperature affect people's psychological feelings
Lighting not only has the function of illuminating, but also has an impact on people's psychology: the higher the color temperature, the cooler it will feel, and the lower the color temperature, the warmer it will be. Psychologists have found that in a red environment, people's pulse will speed up, blood pressure will rise, and their emotions will be easily excited and impulsive; in a blue environment, their pulse will slow down and their emotions will be calmer. Different colors have different reflections on taste, which is also related to people's instinctive reactions to seeing objects, such as apples and oranges when they see red and yellow. Red and yellow are sweet, sour and sweet, which can stimulate appetite and increase appetite; while black-green and blue-green feel bitter and affect appetite.
2. Lighting in different areas of shopping malls
Design points Different types of shopping malls and different subdivisions of shopping malls have different specific requirements for lighting effects, so the focus of their lighting design is also different. From the perspective of the overall lighting environment, low-end small commercial retail systems generally have an illuminance of 500Lux to 1000Lux, and a color temperature of 5500K to 6500K of cool white light. The lighting system commonly used in mid-end supermarkets has an average illuminance level of 250Lux-500Lux and a neutral color temperature of 4000K-5000K. The high-end supermarket environment lighting level is relatively low, generally 50Lux - 250Lux, by strengthening the accent lighting and decorative lighting to adjust the illuminance level in the space, resulting in a sharp contrast, and the color temperature is a typical warm color of 2700K-3000K. At present, the main lamps and light sources used for environmental lighting in shopping malls include downlights of compact energy-saving lamps and fluorescent lamp brackets of T5/T8, grille lamps and metal halide lamps.
3. Owners' concerns and countermeasures for using LED
Shopping mall lighting applications are considered to be the first mature application places that LEDs can enter. Although some shopping mall lighting renovation projects have been launched, LEDs are emerging light sources, and shopping mall users still have some questions and concerns about the application of LEDs. , its main performance and problems are as follows:
(1) Insufficient luminous flux, limited lighting effect
Because most of the standard alternative light sources are currently used, the total luminous flux is not enough due to the limited power. Countermeasures: Monolithic and modular LED fixtures are the way to go; wait for LED efficacy to continue to rise.
(2) The color rendering is not good, and the lighting quality cannot be guaranteed
Countermeasures: LED light sources packaged with high color rendering phosphors; red or amber chips are mixed with blue light to obtain high color rendering light sources.
(3) The reliability is not high, worry about after-sales service
At present, the quality of LED products on the market is uneven, the competition is disorderly, and the negative impact is large. Countermeasures: Manufacturers choose high-quality raw materials, innovate technology and strengthen production control; users should choose suppliers with strength and brands; expect the country to promote the effective implementation of LED lighting standards as soon as possible.
(4) The price is too high and the one-time investment is high
Countermeasures: With the expansion of the market size, the price of LEDs will drop rapidly: the comprehensive income of LEDs is high, and business models such as installment payment and EMC can be considered; the introduction of price subsidies for the LED industry by the state will promote the enthusiasm of the owners to apply.
