Q1 evaluation index should have change? Illuminance value, uniformity, color temperature, color rendering index should be the same? Question background GB50034 standard main content and the scope of this standard shall be formulated by the general provisions, the term, general standard quality and quantity, lighting, lighting, lighting energy saving, light distribution and control, lighting management and supervision of eight chapters and three appendix. Main provisions of the living standard, public and industrial building lighting, lighting quality and lighting power density. This standard applies to new, rebuilding and expansion of housing, public and industrial building lighting design. ( Public library, cinema, hotel, office, commercial, schools, hospitals, museums, traffic, sports, exhibition hall) Number of lighting engineering evaluation indexes stipulated in the standard lighting illumination or brightness ( Horizontal illuminance, vertical illuminance, cylindrical illuminance) Lighting quality uniformity, color temperature, color rendering index, glare, light pollution lighting energy saving electricity lighting safety indicators or power density electrical safety, protection safety, mechanical safety Q2 with LPD evaluate lighting energy saving is the best way? Is there a better way for energy saving?

80 Q3LED enter indoor, on the premise of meet the requirements of Ra, which are put forward on the LED light source should be required? LED the discrete spectrum of visual effect in long hours at work places have any effect, Light biological safety) ? If there is influence how should solve? Question background lighting source option 3. 2. 1 choose lighting light source shall comply with the relevant provisions of the current national standards. 3. 2. 2 select light source, in satisfies the requirement of color rendering, the startup time, and so on conditions, according to the efficiency of the light source, lamps and ballast, life, and the price determined after comprehensive technical and economic analysis and comparison. 3. 2. 3 lighting design according to the following conditions choose low light 1 room, such as office, classroom, meeting room and instrumentation, electronic and other production workshop appropriate USES fine diameter straight tube fluorescent lamp form; 2 puts forward appropriate USES fine diameter straight tube fluorescent lamp, compact fluorescent lamps or low power metal halide lamp; Three highly high industrial workshop, shall, in accordance with requirements of the production use, use a metal halide lamp or high pressure sodium lamp, also can use high power thin tube diameter fluorescent lamp; 4 fluorescent lighting places shoulds not be commonly use high pressure mercury lamp, should not be using the fluorescent ballast high pressure mercury lamp; 5 usually, indoor and outdoor lighting should not use general lighting incandescent; Under special circumstances need to use, the power rating should not exceed 100 w. The choice of light source, thin tube diameter (1 ≤26mm) Tricolor straight tube shape T8 and T5 fluorescent lamps for below 4 ~ 4. 5 m in the room, such as office, classroom, meeting room, hospital and instrument, electronic workshop, etc. 2, puts forward appropriate USES fine diameter straight tube fluorescent lamp, compact fluorescent lamps or low power metal halide lamp height 3, high industrial workshop appropriate USES metal halide lamp, or high pressure sodium lamp, also can use high power thin tube diameter fluorescent 4, unfavorable use fluorescent high pressure mercury lamp, should not use the high pressure mercury lamp ballast fluorescence 5, under normal circumstances should not use incandescent lamp, under special circumstances can use 100 w bulb conditional place to expand the application of light emitting diode Q4 should reflect in the new standard incandescent light bulb? The efficiency of lamps and lanterns how? 3 question background. 2. Four of the following workplace can use incandescent lamp 1 requires instantaneous startup and continuous adjustable light, when using the other light source technology economy is not reasonable; 2 place for strict in preventing electromagnetic interference; 3 open to turn off the lights frequent places; 4 illumination requirement is not high, and lighting time shorter places; 5 places with special requirements for decoration. 3. 3. 2 in satisfies the requirement of glare restrictions and light distribution condition, should choose the lamps and lanterns of high efficiency, and shall meet the following requirements the efficiency of the fluorescent lamps and lanterns should not be less than 1 in table 3. 3. 2 - The provisions of 1.
