1, Selection of material for lamp trough
The lamp groove is the basic support structure of LED linear lamps, and its material directly affects the heat dissipation performance, durability, and stability of the lamps. When choosing the material for the light trough, the following points should be given priority consideration:
Heat dissipation performance: Supermarket environments are complex, and lighting fixtures are prone to generate heat when working for long periods of time. Therefore, the material of the light trough should have good heat dissipation performance. Aviation aluminum is an ideal choice as it is more durable and has better heat dissipation than ordinary aluminum. In addition, aluminum has strong compressive and heat resistance, which can effectively prevent deformation and extend the service life of lamps.
Durability: Supermarkets are crowded, and lighting fixtures are easily affected by external forces, so the material of the light trough should have sufficient strength and toughness. Aircraft aluminum materials are made of solid materials, with a thickness of at least 1mm, or even around 2mm, to ensure the stability and durability of the lighting fixtures.
Aesthetics: The color and surface treatment of the light trough material can also affect the overall aesthetics. The high-quality aluminum shell undergoes oxidation and alkali treatment, resulting in a more beautiful appearance and enhanced resistance to pressure and heat.
2, Selection of Lamp Strip Materials
The LED strip is the core luminous component of LED linear lamps, and the selection of its material directly affects the luminous effect and service life of the lamp. When selecting materials for light strips, the following points should be taken into consideration:
Luminous effect: High quality LED light strips emit light uniformly without any graininess, effectively improving the lighting quality of supermarkets. When choosing, you can pay attention to the quantity and distribution of light beads. Generally, around 120 LED light strips are more suitable. At the same time, the style of the light strip is also important, and the white lampshade can blend in with the supermarket space for a better visual effect.
Durability: Supermarket environments are complex, and light strips are easily affected by pollutants such as dust and water vapor. Therefore, light strips with good waterproof and dustproof performance should be selected. In addition, the high and low temperature resistance of the light strip is also important to ensure normal operation in different seasons.
Safety: The safety of the light strip cannot be ignored. Transformers with 3C or CQC markings should be selected to ensure the safety of the lighting fixtures. At the same time, low-voltage light strips (such as 24V low-voltage light strips) are safer to use, with uniform brightness and no glare.
3, Selection of Cover Material
The cover plate is the protective layer of the LED linear lamp, and the choice of its material directly affects the transparency, aesthetics, and durability of the lamp. When choosing the material for the cover plate, the following can be considered:
Polycarbonate (PC): PC material has high transparency, strength, and heat resistance, making it very suitable for outdoor environments and places that require waterproof and dustproof effects. In addition, PC materials have high light transmittance and can maintain transparency for a long time, making them less prone to aging.
Acrylic (PMMA): Acrylic, also known as organic glass, has high transparency and flexibility, and is easy to process and shape. However, its heat resistance and impact resistance are relatively poor, making it more suitable for indoor environments.
Glass: Glass cover plates have high transparency and beautiful appearance, which can add a sense of luxury to supermarkets. However, glass is relatively heavy and fragile, and its price is also relatively high, so when choosing, it is necessary to balance its aesthetics and practicality.
4, Selection of light source and spectrum
The selection of light source and spectrum directly affects the illumination effect of LED linear lamps. When choosing, attention should be paid to the following points:
Full spectrum: The light emitted by the full spectrum LED linear lamp contains all colors in the visible spectrum, approaching natural light, with a more natural and soft light, and does not produce a dazzling feeling. This is very important for enhancing the shopping atmosphere and customer experience in supermarkets.
Color rendering index: The higher the color rendering index (Ra), the better the color reproduction of the object. To ensure the true reproduction of colors, LED linear lights with a color rendering index of 95 or greater should be selected.
Color temperature: Color temperature mainly reflects the degree of warmth or coldness of the light color. Supermarket environments generally choose a color temperature range of 3000K to 4000K, which can provide a comfortable lighting environment and enhance the display effect of products.
5, Considerations for preventing blue light and flicker
Blue light and flicker are two common issues with LED lighting fixtures, which have a certain impact on vision. When choosing LED linear lights, attention should be paid to their anti blue light and flicker performance:
Anti blue light: In the blue light hazard level, RG0 level means that the product has no blue light risk at all. To protect the eyesight of customers and employees, LED linear lights without blue light hazards should be selected.
Strobe: Strobe refers to the phenomenon where a light source flashes rapidly in a short period of time. Long term exposure to flickering environments can cause damage to vision. Therefore, LED linear lights without video flashing should be selected.
6, Considerations for anti glare design
Anti glare design is crucial for improving the lighting quality of LED linear lights. When choosing, you can pay attention to the following points:
Light control: By controlling the angle of light reflection and utilizing the principle of physical refraction, light is reflected from different angles in all directions to reduce the brightness of the field of view and release ultra dense soft light. This can provide sufficient illumination brightness while avoiding glare.
Multiple reflection: Multiple reflection technology can effectively reduce shadows and make light more uniform and soft. This is very important for improving the lighting effect and customer experience of supermarkets.
7, Consideration of Service and Design
When choosing LED linear lights, the brand's service and design capabilities should also be considered:
Professional services: Some brands have professional lighting design teams that can provide free professional whole house unmanned lighting design solutions. Choosing products from this brand not only saves time and effort, but also ensures the lighting effect and quality.
Customized service: Select LED linear light brands that can provide customized services based on the specific needs and spatial layout of the supermarket. This can meet personalized needs and improve lighting effects.
