In addition to the brand logos and serial numbers of various manufacturers or distributors, the signs printed on fluorescent tubes in my country often appear symbols that indicate the type of fluorescent lamp, the diameter of the glass tube, and the color temperature, etc., and their meanings are as follows:
(1) Symbol indicating the type of fluorescent lamp
YZ: stands for ordinary straight tube fluorescent lamp (Y is "fluorescent lamp", the first letter of Chinese pinyin, Z-- is the first letter of "straight" Chinese pinyin)
YK: means quick start fluorescent lamp (K means "quick start")
YS: Indicates instant start fluorescent lamp (S means "instant start")
YG: stands for high frequency fluorescent lamp
YDN: Indicates that the fluorescent lamp is activated in a single end
YDW: Indicates a single-ended external start fluorescent lamp
YH: Represents circular fluorescent lamp
YPZ: Represents self-ballasted fluorescent lamps for general lighting
D: electronic type (inductive self-ballasted lamp symbol omitted)
Note: The International Electrotechnical Commission (the English abbreviation is IEC) is expressed as: PS: warm-up start; RS: quick start; S: hot cathode single-pin instant start. Such symbols are commonly used in foreign products.
(2) A symbol indicating the diameter of the glass tube of the lamp
Use TX to indicate the diameter of the glass tube of the lamp. Among them, T: refers to the tube type glass tube; X: refers to the diameter of the glass tube, which is X/8in (English).
Example: T12 means that the diameter of the tubular glass tube is 12/8in. At present, the metric size can be used to directly express the diameter of the glass tube in the naming of the domestic model.
(3) A symbol indicating the color temperature of the lamp
RR: means daylight color (color temperature 6500K)
RZ: Represents neutral white (color temperature 5000K)
RL: means cool white (color temperature 4000K)
RB: Represents white (color temperature 3500K)
RN: Means warm white (color temperature 3000K)
RD: Represents the color of incandescent lamp (color temperature 2700K)
(4) Other symbols
CE: Indicates that radio interference meets the requirements.
In addition, the lamp will also have technical parameters such as rated voltage and power.
Example:
1) T8YZ36RR: It means that the tube diameter is 1in (inch), the power is 36W, and the daylight color ordinary straight tube fluorescent lamp (such as directly expressing the glass tube diameter in metric size, the above example can also be marked as YZ36RR26, indicating that the tube diameter is 26MM ).
2) YK20RN32: It means that the tube diameter is 32mm, the power is 20W, and the warm white quick-start fluorescent lamp.
3) YDN9-2U·RR: It means the 9W2U daylight color single-end internally activated fluorescent lamp.
4) YDW16-2D·RN: 16W2D type warm white single-ended external start fluorescent lamp.
5) YPZ220/13-3U·RL·D: 220V13W3U type cool white electronic self-ballasted fluorescent lamp for general lighting. (The structure of the spiral self-ballasted lamp is represented by S, that is, S can be used to replace 3U)
