Outdoor lighting installation notes

Ground: according to the specification requirements of lamps must have a good connection and grounding, I lamp grounded into 0 lamp approximation;

The voltage fluctuation allowed: HCI ceramic metal halide lamp, metal halide lamp and quartz HQI NAV high pressure sodium lamp requires voltage fluctuation in a short period of time shall not exceed +/-5%, the fluctuation range of long-term allowed +/-3%, large voltage changes will shorten the service life of the lamp and causes the color offset;

The use of source: frequent switch will shorten the service life of the lamp;

Ballast: the distance between the light source and the ballast is restricted, generally not more than 3 meters;

Starting current: HCI, HQI and NAV according to different ballast, 2 times the lamp starting current can be as high as the working current, so the circuit design must take into account the current switch, otherwise easy to trip;

Light flux: source parameters was relatively stable at 100 to 300 hours, T type and TS type ignition position is horizontal, while E is in the vertical lamp, when the source of different ignition position, the luminous flux, color temperature and longevity, there are significant differences;

Color deviation: for all HQI and HCI metal halide lamp, lamp and lamp may exist between color deviation, deviation of the color is due to the effect of power supply voltage, ballast and lamp design and other external factors, factors affecting the consistency of the lamp:

: internal consistency of the arc tube (filled with mercury, electrode gap, volume, status and size) determines the consistency of lamp power and cold temperature, these have affected the halide density, so as to determine the consistency of the lamp color temperature. At present, the advanced level of foreign countries, the same batch of light source factory related color temperature tolerance can be controlled at around +/-100K, while the domestic advanced level in +/-300K. For the 3000K halogen lamp, the difference in color temperature of 600K with the naked eye is easy to feel.

External factors: the different parameters of the ignition position is 600K, the power supply voltage, the capacitor and the related provisions of the industry standard, the rated power below 400W, ballast adjustment rate shall be less than 10%; but the electronic ballast supporting Taitong lighting and constant power, can well prevent color temperature deviation.

Installation number: one branch of parallel light suggested that no more than 4, in order to reduce the change of voltage, phase voltage will cause the light color, such as color contrast and customers have special requirements, recommends that customers use HCI ceramic metal halide light source, constant power electronic ballast metal halide lamp accessories, the price is more expensive;

Buried lamp installation matters: first install buried lights embedded in the outer barrel, a light source is installed, must use the compact waterproof silicone toughened glass good, to tighten the screws diagonally uniform, can not be installed in the square lane, HID underground lamp conventional production reserved three core cable 0.5 meters, the external connection to waterproof box, waterproof grade IP67, the company is not equipped with the factory waterproof box (to another company), buried lights must have a hydrophobic layer above 20CM, the best and the drainage channel 10, underwater lights; installation considerations: routine production of underwater light reserved three core cable 1 meters, the external connection to use waterproof box, waterproof grade IP68, the company is not equipped with the factory waterproof box (to another company), for safety reasons, underwater lights are generally required for transformer transformer, waterproof grade IP44, the underwater light anti contact Class III, transformer must be installed in the pool shore, can not be installed under the water;

Pan (CAST) light installation considerations: Pan (vote) in the installation of light source, good waterproof silicone toughened glass pressing, floodlight according to lighting design requirements to adjust the angle, all pan (CAST) lamp, underground lamp and wall lamp, not covered by the cover, the distance in the label the product has marked all the lamps can not be installed on the surface of combustible material (combustible surface refers to the 130 degree burns objects);

The provisions line number and rated current: the minimum cross-sectional area of the wire

Rated current (A) nominal cross-sectional area (mm2)

Wire wire is less than or equal to 0.2

> 0.2 and less than or equal to 30.5

> 3 and less than or equal to 60.75

> 6 and less than or equal to 101

> 10 and less than or equal to 161.5

> 16 and less than or equal to 252.5

> 25 and less than or equal to 324

> 32 and less than or equal to 406

> 40 and less than or equal to 6310

Light source: HID light and electrical installation must match, good must be installed on the lamp holder, the installation can not hand the company's products are equipped with light source, a pair of disposable film gloves in each set of lamps, light source for installation;

Light and electrical facilities: A, no American Standard and European standard of sodium lamp metal halide lamp; B, 150W does not distinguish between American Standard and European standard, and use the same lamp electrical components; C, 250W and 400W metal halide lamp is divided into American Standard and European standard, in strict accordance with the requirements of the wiring and electric light source collocation the;

Waterproof connector installation: all joints waterproof lamp, waterproof connector must be tightened when necessary, waterproof joint line hole position required to be marked with glass glue or silica gel;

Protection grade: IPXX said dustproof and waterproof, the first X second waterproof dustproof, said. Specific definitions in the product catalog.
