GB/T 37637-2019Performance requirements for LED floodlights (English PDF)

1 Scope

This Standard specifies performance requirements for floodlights of which power supply voltage does not exceed 1000V, and LED is used as light source (hereinafter referred to as "lights").

This Standard is applicable to lights that are used in architecture, landscapes, works of art, public places, sports venues.

This Standard is not applicable to lights of which half peak angle is less than 2° (such as searchlight).

This Standard does not involve lights that use LED lights covered in GB/T 31897.1-2015.

4 Classification of lights

4.2 Lights can be classified into white lights and color lights (non-white lights).

4.3 Lights can be classified into light-output non-adjustable lights (hereinafter referred to as "non-adjustable lights") and light-output adjustable lights (hereinafter referred to as "adjustable lights").

NOTE: Light-output adjustable lights might be dynamic dimming.

4.4 White lights can be classified into color-temperature non-adjustable lights and color-temperature adjustable lights.

4.5 Color lights can be classified into color non-adjustable lights and color adjustable lights.

NOTE: Color adjustable lights might be dynamic coloring.

5 General requirements

5.1 Lights shall meet safety requirements and electromagnetic compatibility requirements specified in IEC 60598-2-5:2015, GB/T 17743, GB 17625.1 and GB/T 18595.

5.2 Lights shall provide claimed functions and achieve claimed performances under rated conditions.

6 General test requirements and conditions

7 Technical requirements

7.1.2.3 Rated luminous flux or rated luminous flux at maximum input power (such as dimming and coloring lights and dynamic dimming and coloring lights).

7.1.2.4 For color lights, following information shall be provided:

- about initial rated color coordinate value, for dynamic coloring and (or) dynamic coloring lights, it shall mark rated color coordinate value under maximum rated input power;

- for color lights of which color remains unchanged, it shall indicate light color, for example, green light or red light.

7.1.2.5 For white lights, following information shall be provided:

- rated correlated color temperature (CCT, K) and claimed color tolerance.

For lights that color temperature is adjustable, it shall claim that one or more color temperature values required by color tolerance can be met;

- rated color rendering index Ra and R9. For lights that color temperature is adjustable, if color rendering index changes with color temperature, it needs to indicate color rendering index corresponding to correlated color temperature.

7.1.2.6 It shall provide beam spread or one half-peak divergence, peak light intensity and light intensity distribution map of lights.

7.1.2.7 Use lights of control device of independent light that is separated from light source chamber. It shall provide electrical parameters of driving light source or model specifications of applicable control device as well as corresponding producer (manufacturer). For lights that use control device of built-in light, it shall provide model specifications of control device used as well as corresponding producer (manufacturer).

7.1.2.8 For lights that use replaceable LED module, following information shall be provided:

- applicable LED module model specifications, photometric codes and their corresponding producers (manufacturers);

7.1.2.9 For dimming lights, it shall provide relevant information such as dimming control mode.

7.1.2.10 For lights that angle is adjustable, it shall indicate adjustment range of horizontal and/or vertical direction angle.
