LED panel lights are a popular and energy-efficient choice for lighting applications in both residential and commercial settings. These innovative lights are incredibly versatile, offering bright, uniform illumination that can be easily customized to suit the style and needs of any space. In addition, LED panel light fixtures boast a long lifespan, helping to reduce replacement costs over time.

Logos Lighting has currently released its new generation LED panel lights backlit plus edge-lit series. New panel lights are committed to American and European markets, focusing on office and commercial lighting applications.

New generation panel lights include backlit and edge-lit, dimming, or non-dimming available. Square and rectangle in shape with various sizes applied for different markets.

1) Back-lit LED

Although today’s edge-lit panel lights are more popular than back-lit panel lights, backlit LED panels are still on the market because they are able to produce adequate light. Especially backlit panel lights are prevailing ceiling lights at schools, work offices, hospitals, etc. Here make analyses on backlit structure and performance.

The back-lit ceiling panel light works with the LED light sources at the back of the panel. The light will project light forward across the full scope of the light panel from the front. For backlit panel lights, LEDs can be placed over a large area to illuminate a light panel. Such LED modules are flexible, user-friendly, and easy to repair. To be mentioned, since a certain distance between the SMD LEDs and the panel is required to enable an overall uniform and bright illumination of the entire lamp, this type of light panel cannot be built as thin as one may desire. So backlit is heavier and thicker than edge-lit panel light.

Obviously, backlit panel light is more efficient on light output because it did not cause so much light loss on the structure. LogosLED’s back-lit LED panel light efficacy is up to 120lm/w.

One problem might occur in lighting applications since direct-lit panel light is able to project light across the full range of the light panel from the front, the light emission might be strong and striking with abundant light output.

2) Edge-Lit

Edge-lit LED panel lightStructurally, edge-lit panel lights are constructed with aluminum frames and light panels. It uses high-efficiency PMMA light guide plates and nano-grade diffusers, which makes it optically energy efficient in lighting. Moreover, since LEDs used in edge-lit panel light are placed at the edges, light is not straightforward but re-directed to the viewing surface, thus making light output smooth and soft. And compared to the backlit panel light, the edge-lit LED panel light is thinner.

New generation edge-lit panel light efficacy can reach up to 130lm/w, though a little bit lower than backlit panel light. It costs less on raw materials and has good performance.
