The basic function is to provide lighting and
AD711JR datasheet and light electrical connection, in addition to many other important functions. Most light sources emit light all-round, this is a waste for most applications, and
AD711JR price and the resulting glare. Therefore, most lamps, the adjustment of the light to the desired position, while the optical losses to a minimum to reduce light glare, has a satisfactory shape and
AD711JR suppliers and strengthen the lights lit and unlit environment is decorative lighting function. Lighting must be durable, as the light source and can, if necessary, and sometimes also for the control of electrical accessories to provide an electrical, mechanical and thermal studies on the safety case.
source of protection: lighting in addition to required electrical connections, mechanical support must also be well to be protective, the degree of protection depending on requirements.
suitable mechanical properties: lighting components must be strong enough mechanical strength to ensure proper installation and use of durability, while the full strength of a strong suspension of metal parts must have sufficient resistance to corrosion.
housing requirements: outdoor lighting must be strict dust and splash, and some special requirements should be provided with interior lights
protection against water and dust intrusion. Use protection code into the housing of the enclosure. IP protection class is composed of two numbers, first number indicates the light dust, to prevent intrusion of foreign objects of protection (protection of contact with objects, foreign objects of protection); second number indicates the lamp against moisture, water intrusion Closed level (water level of protection); higher the number, that its protection level higher. IP (International Protection) Table lamps Protection class 1 - 4 Table 1-5.
Electrical requirements: lighting can also be based on the way to protect users against electric shock classification. Type 1 lamps must
basic edge, all metal body with a ground terminal, the terminal to the grounding system with the power connected. Type 2 protection by the double insulation of the lamp to work under two-wire lighting circuit. Type of lighting is not ground zero, only ordinary insulation measures. A variety of electrical components and wiring must be safe at work.
thermal requirements: the various components of the operating temperature can not exceed the European standard EN60598 (UK published BS4533,
BSI1981-1990) under the value. Heat durability test was higher than the rated ambient temperature lOcC, switching cycle alternating, over-voltage of 5% N10% under the conditions of work for 7 days. Test of time and over-voltage value depends on the light source and control electrical category.
marking requirements: must have a manufacturers standard ridicule, supply voltage, power rating, classification, rating the highest temperature. Signs must be durable, production methods stand the test.
test: a new design into production at the factory to be set before the test project, including mechanical testing, test case, electrical testing, thermal testing and photometric testing.
