Test Conditions for Optical Characteristics
Junction Temperature vs. Case Temperature
Philips Lumileds specifies performance at constant case temperature for LUXEON Altilon. This datasheet specifies performance at constant case
temperature of 25°C, except where noted. The data sheet that follows will specify performance at constant case temperature of 25°C.
Case temperature refers to the temperature of a thermocouple mounted under the head of one of the mounting screws, and is a value that can
be measured rather than calculated (see Figure 7). A junction-to-case thermal resistance of 2.1°C/W is assumed for the 1x2 configuration and
1.4°C/W for the 1x4 configuration. This approach will more accurately capture product performance capabilities compared to average junction
temperature alone.
Environmental Compliance
Philips Lumileds is committed to providing environmentally friendly products to the lighting industry. LUXEON Altilon is compliant to the
European Union directives on the restriction of hazardous substances in electronic equipment, namely, the RoHS, ELV, and REACH directives.
Philips Lumileds will not intentionally add the following restricted materials to the LUXEON Altilon product: lead, mercury, cadmium, hexvalent
chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).

Notes for Table 1:
1. Philips Lumileds tests flux values via a pulsed measurement at a case temperature of 25°C.
2. Minimum luminous flux guaranteed within published operating conditions. Philips Lumileds maintains a tolerance of ± 10% on flux
measurements.
3. ‘*’ Indicates the inclusion or exclusion of the spade lug connector, indicated with an ‘L’ for spade lug, and an ‘S’ for those parts without.
See Part Number Description below for more details.

Typical Luminance Performance
Typical luminance is calculated based on the total lumens emitted from the smallest rectangle covering the optical source. This method accounts for
variations in chip and phosphor placement as well as spacing between discrete chips. Figure 1 below indicates the orientation used to determine the
source area used for luminance calculations.

For the 1x4 configuration, the typical X and Y dimensions are 4.51 and 1.06 mm, respectively.
For the 1x2 configuration, the typical X and Y dimensions are 2.21 and 1.06 mm, respectively.
Typical Use Condition Matrix—Relative Flux
Normalized to T
c
= 25°C, 1000 mA, 20 msec pulses
The graphs on the next page predict the relative flux under various use conditions normalized to the test conditions of 1000 mA pulsed operation
(20 msec pulse) at case temperature of 25°C. These graphs can be used to determine the effects of case temperature and forward current on the
values of minimum and typical flux to define performance at the expected use condition. For example:
Given a flux at T
c
= 25°C and 1000 mA (20 msec pulse) of 700 lm for 1x4 configuration, the flux value under different conditions can be predicted.
If expected use condition is 700 mA at T
c
= 100°C, the relative percentage of flux would be approximately 70% of the reference value.
