New Generation LED Panel Light

SYHDEE has currently released its new generation LED panel light back lit plus edge lit series. New LED panel light is committed to American and European market, focused on office and commercial lighting application.

New generation LED panel light includes back lit and edge lit, dimming or non-dimming available. Square and rectangle in shape with various sizes applied in different market.

1) Back Lit LED Panel Light

Although today edge lit panel light is more popular than back lit LED panel light, back lit LED panel light is still on the market because it is able to produce adequate light. Especially back lit panel light is prevailing ceiling light at school, work office, hospital,etc. Here makes analyses on back lit structure and performance.

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 back lit LED panel light, LEDs can be placed over a large area to illuminate a light panel. Such LED modules is 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 back lit is heavier and thicker than edge lit LED panel light.

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

One problem might occur in lighting application, since direct lit LED 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 LED Panel Light

To reduce cost and soften light output, edge lit LED panel light is designed for more economic lighting solution. Today edge lit is very prevailing in recessed ceiling, where it is able to perform better than back lit(direct lit) LED panel light.

Structurally, edge lit LED panel lights are constructed with aluminum frame and light panel. 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 straight-forward but re-directed to the viewing surface, thus makes light output smooth and soft. And compared to back lit panel light, edge lit LED panel light is thinner.

New generation edge lit LED panel light efficacy can reach up to 100lm/w, though a little bit lower than back lit. It costs less on raw materials and have good performance.
