Lamps are divided into several categories?

(1) by installation:

Portable lamp: table lamp, hanging wall lamp, floor lamp

Fixed luminaires: ceiling lamps (ceiling lamps), chandeliers, wall lamps, recessed lights, track lights.

(two) use environment:

1.EN specification

1) indoor use: the use of symbols, the external surface of metal parts to be treated;

2 outdoor use: with the symbol, the external surface of metal parts to be anti-corrosion treatment;

Special requirements: water spray test (which requires a minimum diameter of 3.2mm Water Leakage hole), metal anti-corrosion outer surface to.

2.UL/CSA specification

1) dry environment (DRYLOCATION): at most temporary moisture. For example, living room, living room, kitchen and other indoor environment.

2) the tidal environment (DAMPLOCATION): at least periodically appears the phenomenon of moisture liquefaction. With the bathroom, cellar freezers and other indoor humid environment and the interior in the balcony door, day rain proof cover is on the cover of the outdoor environment.

3) wet environment (WETLOCATION): at least will suffer rain or splash. For example, underground, water and all outdoor environment and car wash and other indoor environment can be poured into the water.

Note: tidal environment, wet environment, the main requirements: water spray test (that is, the minimum water leakage hole 3.2mm), metal parts inside and outside the surface to be treated with corrosion resistance, the lamp head conductive contact sheet need corrosion resistance (copper end).

(three) by using the standard category

1 North American system: mainly UL/CSA specification system. Voltage of AC100V ~ 127V, 60HZ, including North America, South America, some countries, as well as Japan, Philippines, Taiwan and other former American colonies. ULLab. according to CSA standards for product testing, qualified can be exported to Canada cULMARK.

Current ULFILE:

1 (E219568) portable luminaires;

2 (E203552) fixed luminaires;

2 the International Electrotechnical Commission (IECInternationalElectrotechnicalCommission) system, including: Europe, Asia, Australia, Africa, Southeast Asia, most countries and regions. The specifications listed are for reference to the EN60598 series standard plus some special requirements of the country (region) such as voltage, plug type, etc.. China in 1957 to participate in IEC, is currently a member of the IEC board of directors, Executive Committee and the rating agency. Lighting industry national standards GB7000 series corresponding to the IEC60598 series. Where IEC (EN) products can be subdivided into the following categories:

(1) according to the degree of protection against electric shock:

Class A.CLASS0 lamp, no symbol.

Features: power supply voltage above 50V high voltage / single insulation / no grounding.

Class B.CLASSI lamp, no symbol. Single layer insulation structure, exposed contact metal grounding. CLASSI lights can be part of the structure for the CLASSII structure.

Features: power supply voltage above 50V high voltage / single layer insulation / grounding.

Class C.CLASSII lamp, with the symbol "". Class II lamps are usually double insulated, but may have a part of the structure of the CLASSIII structure (such as the low voltage part of the transformer). Built in transformers shall be designed for two types of lamps.

Features: power supply voltage higher than 50V / double insulation / no grounding.

Class D.CLASSIII lamp. With the symbol ", said the power supply for the safety of the extra low voltage SELV (external transformer in the straight lamp) features: power supply voltage of 50V below the low voltage / single insulation / no grounding.

(2) according to the IP index of dust proof solid foreign body and moisture proof ability: IPXX

Number one: dust proof solid foreign body index, divided into seven grades 0-6. The bigger the number is, the stronger the ability to prevent solid foreign matter.

0: no protection; 1: more than 50mm of solid foreign body;

2: the prevention of more than 12mm of solid foreign body; 3: more than 2.5mm of solid foreign body;

4: more than 1mm of solid foreign bodies; 5: dust; 6: dust tight

Second digit: moisture resistance index, divided into 0-8 nine grades. The larger the number, the stronger the moisture resistance;

0: no protection; 1: anti drip (vertical); 2: anti drip (tilt of 15 degrees);

3: anti water (60 degrees); 4: 5: prevent water splash:

6: prevent violent waves; 7: anti flooding effect; the 8: anti dive effect.

Explain

1) ordinary lamp protection level is IP20, generally do not mark.

2 outdoor lighting protection level IP# are generally IP23 or above, and need to be marked.

(3) according to the flammability of the installation surface:

A. is only suitable for lamps installed directly on non combustible surfaces, with the symbol ".

B. suitable for the installation of lamps on ordinary combustible surfaces, with the symbol "".

C. can be installed on the ordinary combustible surface and insulation material may cover the occasion of the lamp (ie embedded), with "".
