LED Recessed Luminaire关于热保护

LEDRecessed Luminaire 关于热保护该如何选择豁免?
Item (c)去做测试?

11.5 Thermal protectors
11.5.1 General
11.5.1.1 A recessed luminaire shall be provided with a thermal protector unless the luminaire is:
(a) intended to be installed in concrete only, as specified in Clause 11.4.6;
(b) inherently protected, complies with the temperature test of Clause 14.8, and is marked in accordance with Table 20.1.1, Item 2.24;
(c) intended to be installed in the ground only and is marked in accordance with Table 20.1.1, Item 2.27;
(d) intended to be installed in an outdoor canopy or marquee where it is not intended to be covered with thermal insulation, and is marked in accordance with Table 20.1.1, Item 2.26;
(e) fluorescent, when the ballast is required to have a thermal protector in accordance with Clause 8; or
(f) HID, Type IC, and marked in accordance with Table 20.1.1, Item 2.23.

有荧光灯和HID灯,没LED灯具。

11.7.1 Temperature
11.7.1.1 A luminaire shall comply with the normal and abnormal temperature tests in accordance with Table 11.7.1.1.

LED Driver 如果带有热保护装置,则可以根据(b) inherently protected, complies with the temperature test of Clause 14.8, and is marked in accordance with Table 20.1.1, Item 2.24;
这一天争取豁免。
温升测试可以按照fluorescent的测试要求进行。
