Why Thermal Management is Important?

Thermal management has a huge impact on various aspects of the LED light source. However, LEDs are at a much compact scale which makes thermal management a critical concern for luminaire design. With good heat dissipation, the aging and degradation of an LED can be significantly slowed down. This ensures a longer lifetime and better durability of the luminaire.

Lorbits limited the junction temperature of LEDs and maximized luminous efficacy that heat does not stagnate in the luminaire. The LEDs degrade slowly and their quality is maintained for longer.

Color Consistency Matters

LED production is a complex process that does not ensure 100% consistency between LEDs. LED Binning is the sorting process based on the output of light intensity and color, measuring consistency in a range between 2 and 7 steps.

Steps are measured in relation to a MacAdam ellipse, a Standard Deviation Color Matching (SDCM) protocol describing human visibility of different sources, by how far they deviate from a reference center color. The human eye cannot detect chromatic variation between any two points inside a given ellipse.

To guarantee lighting uniformity, Lorbits supplies all products with 3-step binning LEDs, the tightest binning possible, and on the black body curve. Any range beyond 3-steps can compromise the success of a project installation.

What is flicker?

Flicker is the change in brightness of light. The above graph shows how even though incandescent and fluorescent bulbs might flicker at the same frequency (Hz), the increased flicker % in fluorescents is what causes the new distress from flicker.

LEDs are called a Solid State Lighting (SSL) technology. This lighting technology can drop in intensity down to zero in the AC cycle! This is one of the greatest reasons why early LEDs are rejected as a poor choice for healthy lighting.

LED flickering can be tied back to the driver component within the lamp. The essential purpose of the LED driver design is to rely on a simple circuit to control output current, but without altering the frequency, the LED becomes likely to show visible flicker. However, if the driver design of the LED bulb meets the requirements of both a stable DC current and ample ripple suppression, there should be no flicker. Unfortunately there are companies that care more about their bottom line than the health of their customers.
