Appearance Characteristics of Panel LED Lamp
based on design components, shape, and style.
LED panel lamps come in square, rectangular, circular, and irregularly shaped varieties, including diamond and leaf shapes. It's crucial to pick a panel light that complements your current decorating style and personal preferences.
The LED lamp's panel size
Panel LED lamps come in a variety of sizes, including 7 inches, 9 inches, 12 inches, and more.
The length of both sides of a panel LED light typically indicates its size, such as 300 x 300 mm, 30 x 30 cm, 300 x 600 mm, 30 x 60 cm, or 3030 x 3060. Depending on the light sources, optical design, structural design, and luminous efficiency of various manufacturers, the appropriate area and power consumption vary. 300mm by 300mm is typically appropriate for spaces that are 3–8 square meters in size and have a power output of about 10w. On the other hand, rooms that are 6–12 square meters and have a power of about 18W are appropriate for 300mm*600mm. Other dimensions include 300 x 1200 mm, 600 x 600 mm, 600 x 1200 mm, and so on. There are also custom panel LED lamps available, albeit there might be a minimum purchase number needed.
Panel LED Lamp Optical Performance
Among the extensive technical indexes are:
Spectral characteristics, chromaticity, luminosity, peak wavelength, spectral bandwidth, axial luminous intensity, colour temperature, colour rendering index, luminous flux, radiant flux, luminous efficacy, colour coordinate, colour purity, main wavelength, colour rendering index, illumination, and luminance are all included in the light performance. For panel LED lamps used for daily lighting, colour temperature, colour rendering index, illumination, and brightness are the most crucial factors.
Colour Temperature of the LED Panel Lamp
Panel lights are typically installed in areas like the office, bathroom and kitchen that need a lot of brightness. Cold light with a colour temperature higher than 5000k is usually selected. However, based on individual tastes, panel LED lamps with colour temperatures ranging from low to high are available.
LED panel lamp brightness
Luminous flux and power often determine how brilliant an LED panel lamp is. As long as the light-emitting area is constant, the brighter the panel light, the greater the power and luminous flux.
Two varieties of panel LED lamps can be distinguished based on their light-emitting properties:
One is the backlit panel light, which diffuses light using a diffusion plate and associated optical design. In general, they are thick, bright, and uniformly lit.
The other is the edge-lit panel light, which produces consistent light output by using a light guide plate. They demand more computing power, are slimmer, and have less brightness.
Panel LED Lamp Heat Dissipation Efficiency and Structural Design
Since LEDs are heat-sensitive semiconducting light sources, the panel light's ability to dissipate heat is essential for preserving the PN junction's temperature and halting light deterioration.
High-quality panel LED lamps typically take into account both appearance structures and heat dissipation structures from chip packaging to light fixtures. To reach a comparatively low working temperature, they employ unique materials including ultra-low thermal resistance materials, high thermal conductivity and long-life chip bonding glue, and manage the overall thermal resistance. Because inadequate heat dissipation performance can have a major impact on light output, light decay, and the panel light's overall lifespan, it is imperative to use superior heat dissipation structures and materials.
Panel LED Lamp Electrical Performance
Performance of the Power Supply
For panel LED lamps, constant-current is frequently utilised. Higher efficiency is preferable. The power supply's output current should be as stable as possible, which implies that the ripple current should be as low as feasible. The power supply's power factor should be as high as feasible since this shows that it has little effect. A higher power supply efficiency indicates a higher and more energy-efficient power supply conversion efficiency.
Consumption of Power
The size of the room, the lamp's size, and the required brightness can all be taken into consideration. In general, the size of an LED panel lamp has a direct impact on its power.
Panel LED Lamp Material
Using a frame
Selecting a panel LED lamp with a strong frame might increase the fixture's longevity. Steel, PC, and aluminium alloys are common materials.
Plate of Diffusion
The diffusion plate's job is to disperse light uniformly. Selecting materials with high transmittance, like acrylic, PC, PS, etc., is essential. Although acrylic's transmittance may typically approach 92%, its anti-aging properties are marginally worse, thus it depends on personal preference.
Guide Plate for Light
The light guide plate's job is to steer and reflect light, which has a direct impact on the lamp's overall light degradation and efficiency.
