Analysis of Explosion-proof Energy-saving Lamps

Energy-saving lamp knowledge I. Energy-saving lamp structure

It is mainly composed of an "upper lamp structure" and a "bottom lamp structure". An energy-saving electronic ballast is incorporated in the interior of the combined structure. The feature is the space below the upper combined structure and the energy-saving electronic ballast. A partition structure is added; in the lower joint structure part, a cavity structure of a growing section is provided; and around the outer wall of the cavity structure of the section, a plurality of through holes are provided for multiple insulation, shunting, heat dissipation, and ensuring The normal service life of energy-saving lamps.

Second, energy-saving lamps form factor

Analysis of energy-saving lamps due to different lamp shapes, divided into U-tube, spiral tube and straight tube type three:

1, U-tube energy-saving lamps: tube shape: 2U, 3U, 4U, 5U, 6U, 8U and other kinds of power from 3W-240W and other specifications.

2U, 3U energy-saving lamps, diameter 9mm --- 14mm. Power generally from 3w-36w. Mainly used for civil and general business environment lighting. In use, it is used to directly replace incandescent lamps.

4U, 5U, 6U, 8U energy-saving lamps, diameter 12mm --- 21mm. The power is generally from 45w to 240w. Mainly used in industrial and commercial lighting. In use mode, it is used to directly replace:

Energy-saving lamps with energy-saving films save 80% Samsung Baishun high-pressure mercury lamps, high-pressure sodium lamps, T8 straight fluorescent lamps.

2, spiral energy-saving lamps: spiral tube diameter, points Φ9, Φ12, Φ14.5, Φ17 and so on.

The number of spiral loops (indicated by T) are: 2T, 2.5T, 3T, 3.5T, 4T, 4.5T, 5T, etc., and the power ranges from 3W to 240W.

3, bracket energy-saving lamps: T4, T5 straight tube energy-saving lamps: T5, T4 straight tube energy-saving lamps. Power is divided into: 8W, 14w, 21W, 28W. Widely used in civil, industrial and commercial environment lighting. Can be used to directly replace the T8 straight tube fluorescent lamp.

Third, according to the material

Energy-saving lamps consist of three parts:

Capillary plastic parts and electronic components lamp caps 1, capillary:

Classification U-type, full-spiral, semi-spiral U-type: 2U3U4U5U6U7U8U9U10U

Full screw: The number of turns of 2.5T and 3T4T spiral lamps is indicated by "T".

Semi-spiral: The number of turns of 2.5T and 3T4T spiral lamps is indicated by "T".

2, plastic parts: According to the material points: PP, PC, PBT

PP material is very soft, mostly used in low block products.

PC material is a high-grade surface light.

PBT material is a high-grade flame retardant material, the surface of a smooth and matte matte.

3, the lamp head is divided into three kinds of materials, copper lamp holder, iron lamp holder, aluminum lamp holder, nickel-plated lamp holder (nickel-plated lamp holder is high-grade product)

Color:: green, white, black.

Lamp head according to specifications: E14, E27, E40 spiral mouth B22 bayonet based on the power size can be divided into: 3W, 5W, 7W, 9W, 11W, 26W, 30W, 36W, 45W, 55W, 65W, 75W,,,

Energy-saving lamps are classified according to phosphors: mixed powder, halogen powder, and three primary colors.

Halogen life is 3000-4000 hours.

The mixed powder has a life of 4000-6000 hours.

Three primary colors are more than 8000 hours.

Fourth, the parameters of high-quality energy-saving lamps

1. Electrical Parameters (1) Voltage Range: Rated Voltage +10%-20%

Energy Saving Lamp (2) Power Range: Rated (Nominal) Power +5%-10%

(3) Power factor: According to the actual situation, select PF>0.6 and PF>0.9

(4) Compliance with safety regulations and electromagnetic interference and electromagnetic compatibility (EMC) requirements (5) Operating frequency of electronic ballast Avoidance Remote control frequency of household appliances (6) Conforms to stable and reliable working requirements in high-temperature and low-temperature environments 2 Optical parameters (1) Luminous flux: The sum of the amount of light emitted by the light source per second: It is used to indicate the amount of light emitted by the lamp, that is, the amount of light emitted. The universal symbol Ñ„ is expressed in units of lumens (Lm).

Light efficiency, luminous flux requirements: less than 15W, light efficiency requirements ≥ 45LM / W; greater than equal to 15W, light efficiency requirements ≥ 60LM / W.

(2) Color rendering index: ≥80

(3) Color temperature: Color temperature deviation is small, consistency is good (4) Start-up time: less than or equal to 1 second 3. Life parameters (1) Effective life of more than 8,000 hours (Lumen maintenance rate of more than 70%)

(2) It can work stably and reliably under the conditions of effective life, high temperature 85°C and low temperature -20°C; and under the above-mentioned temperature conditions, the impact of voltage fluctuations, energy-saving lamps can work stably and reliably. Mechanical parameters (1) The connection strength between the lamp and the electronic ballast meets the specified torque requirement. (2) The connection between the lamp cap and the housing meets the specified torque requirement. Example:

Fifth, the classification of energy-saving lamps

Energy-saving lamps can be divided into two categories: self-ballasted fluorescent lamps (electronic energy-saving lamps) and single-ended fluorescent lamps (PL plug-in energy-saving tube lamps).

Self-ballasted fluorescent lamps come with a full set of control circuits for ballasts and starter lamps, and are equipped with screw-type lamp holders or socket-type lamp holders. The circuit is generally enclosed in a housing, and the control circuit in the lamp assembly is dominated by high frequency electronic ballasts. This integrated compact energy-saving lamp can be directly mounted on the base of a standard white-knit lamp, and the white-knit lamp can be directly replaced, which is convenient to use.

A single-end fluorescent lamp refers to a single-lamp low-pressure mercury vapor discharge lamp. Most of the light emitted by the discharge is activated by a UV-activated phosphor coating. Can be removed from the lamp, used in specially designed lamps, with the control circuit integrated with the lamp, to achieve the purpose of decorating or optimizing the design of the lighting function. The lamp cap has two pins (2P) and four pins (4P). The two-pin cap contains a starter (also known as a bounce) and an anti-interference capacitor, while the four-needle cap does not have any circuit components.
