Fixed and Portable General Purpose LED Luminaires – Mandatory Labeling Content According to QCVN 19

No requirement to mark IP20 on ordinary luminaires.

Apply symbols and explanations on the luminaire or in the manufacturer’s instructions provided with the luminaire (if applicable).

The minimum size of the symbol must be 25 mm on each side.

Luminaires for use with high-pressure sodium lamps requiring an external ignitor (for the lamp)

Luminaires for use with high-pressure sodium lamps that have an internal starting device

Apply symbol labeling on the bulb for luminaires used with high-pressure sodium lamps that either have an internal starting device or require an external ignitor.

Warning against the use of cool beam lamps

Applies when the use of “cool beam” dichroic reflector lamps could adversely affect safety.

L = Line

N = Neutral

E = Earth

Minimum distance from lighted objects (meters)

Applies to luminaires that can cause overheating of the illuminated objects.

Replace all cracked protective shields

Luminaires not suitable for covering with thermally insulating material

Note:

– This symbol must be explained on the luminaire or in the manufacturer’s instructions provided with the luminaire.

– The minimum size of the symbol must be 25 mm on each side.

Luminaires with internal fuses

Notes: Additionally, this luminaire must be provided with information related to the rated current (in A or mA) of the fuse.

Caution, risk of electric shock

Requirement: Symbol height ≥ 15 mm

Note: Constant current luminaires must also be labeled with the maximum allowable voltage value Uout of the control gear.

• either on the luminaire or semi-luminaire
• or on the built-in ballast
• or stated in the manufacturer’s instructions provided with the luminaire.

– Protection class against electric shock or protection against ingress of dust, solid objects, and moisture of the replacement part if not at the minimum level (equal to the requirements of the basic luminaire).

– Rated maximum operating temperature (of the capacitor) tc, expressed in °C.

– Maximum temperature that the insulation of the power supply cable and interconnecting cable must withstand inside the luminaire under the most unfavorable conditions of normal operation, if it exceeds 90 °C.

Use heat-resistant power cable for connection to external cables or wires

– Space requirements to be complied with during installation.

+ connection to a socket outlet with IPX4 rating;

+ correct installation taking into account temporary installation;

+ proper fixing to the stand and, in case the stand is not supplied with the luminaire, the maximum possible height of the stand and the required stability of the stand by specifying the number of legs and the minimum length of the legs.

– For type X attachment with a specially prepared cord: If the external flexible cable or cord of this luminaire is damaged, it shall be replaced by a special cord or a cord exclusively available from the manufacturer or their service agent.

– For type Y attachment: If the external flexible cable or cord of this luminaire is damaged, it shall be exclusively replaced by the manufacturer, their service agent, or a similarly qualified person in order to avoid a hazard.

– For type Z attachment: The external flexible cable or cord of this luminaire cannot be replaced; if the cord is damaged, the luminaire shall be destroyed.

“The light source of this luminaire is not replaceable; when the light source reaches its end of life the whole luminaire shall be replaced.”

– For non-user replaceable light sources:

“The light source contained in this luminaire shall only be replaced by the manufacturer or his service agent or a similar qualified person.”

Examples: Basic insulation or reinforced insulation.

– For luminaires that do not require insulation between the LV supply and the output of the external control gear, no additional information is required.

– For luminaires requiring basic insulation between the primary and secondary parts of the control gear, the following information is required: “The external control gear must provide at least basic insulation between the LV supply and the output.”

– For luminaires not classified as Class III but requiring double insulation or reinforced insulation between the primary and secondary parts of the control gear, the following information is required: “The external control gear must provide at least double insulation or reinforced insulation between the LV supply and the output.”

– Luminaires classified as Class III must have an indication that the control gear must be SELV.

• Durability of marking:

– Step 1: Rub lightly for 15s with a cloth soaked with water, then dry.

– Step 2: Rub for another 15s with a cloth soaked with petroleum spirit.

• Review after completing the detailed test reports/results described in Section 12 – TCVN 7722-1:2017.
• After the thermal testing, the marking must still be legible, the marking plate must not be easily removable, and it must not show curling.

=> Requirement: After the test, the marking must remain legible, the marking plate must not be easily removed and must not be curled.

Note: The petroleum spirit used is a hexane solvent with a maximum aromatics content of 0.1% by volume, a kauri-butanol value of 29, an initial boiling point of approximately 65 °C, a dry point of approximately 69 °C, and a specific gravity of approximately 0.68 g/cm³.
