Description

The lamp position influences the luminous flux LED lamps are often manufactured with integral driver circuitry. Here, the lamp orientation (base up, base down, etc) position can have a significant effect on the junction temperature of the LEDs due to the altered heat flow. Luminous flux, spectrum and color are directly related to junction temperature. The lifetime of LEDs is also reduced as junction temperature is increased. The measurement of photometric properties of LED lamps in the different positions is therefore highly recommended. The ISD-100HFT-BTS256-LED light meter from Gigahertz-Optik is a spectroradiometer with a rotatable, 100 cm diameter, integrating sphere. This combination can be used to measure the luminous flux, spectrum, color, and color rendering index of LED lamps operating in any orientation. The BTS256-LED light meter In its standalone mode, the compact BTS256-LED meter is designed for the convenient measurement of luminous flux, spectrum, color, and color rendering index of single LEDs. A key feature is the conical measurement port at the entry of the internal integrating sphere which enables the measurement of onboard LEDs. The bayonet connector used to attach the conical adapter makes it possible to combine the BTS256-LED with other accessory components. Gigahertz-Optik offers different accessories as part of the BTS256-LED Plus Concept which greatly extends the measurement capabilities of the BTS256-LED.
