safety: magnetic ballast due to its high power consumption, power consumption into heat, surface temperature rise, especially in the power grid voltage fluctuations, the temperature can reach 120~130 degrees, become a fire hazard, such an accident occurs. In the, the ballast can start up at +10, and the voltage is less than -5, and the grid voltage is less than 180V, and it is not easy to start. Inductance ballast power factor is low...

High pressure mercury ballast working principle: when the power supply is switched on, beloved voltage between the ignition electrode and adjacent main electrode and add between the two main electrodes. Due to the ignition electrode and adjacent electrodes near, voltage and after between the two electrodes produced glow discharge, make the tube temperature rise, then between the two main electrodes produced arc discharge (breakdown)....

Light ballast TW value should be as high as possible, and the winding temperature rise,Δt should be as low as possible, i.e. TW value and delta T value, indicating better quality of the ballast. General good ballast tw=130] t is less than or equal to 60 (3) for high strength gas discharge lamp inductance ballast, choose as far as possible with the original logo products, this sign is to indicate internal ballast has thermal protector, inverted triangle winning three points in practical application is indicating ballast surface is the hottest Celsius temperature value, generally for 140 ~ 160. With this sign of ballast, when the lamp or the boot device is damaged (generating abnormal state), the thermal protector will automatically act, which can ensure the safety of the ballast and lamp use....

the living space space to lights, decorative lamps on key, functional principle for style and design. Aguilar lights, desk lamp is paired with each area on the auxiliary light supply, as a way to facilitate and room coordination, modeling also strange lights not ideal. If the decrease rooms, accessible Xidingdeng plus landing lights so that the residing room turns into bright and generous, has the sense of the occasions, floor lamp beside the sofa, sofa side table once again with lighting craft lamp, or even the wall near the placement decrease wall lamp, in order that not only read have regional lighting, but also within the conversation obtain site visitors add a cordial and harmonious environment...

Self - ballast fluorescent lamps is often a massive place of energy-saving lighting merchandise, usually called electronic energy-saving lamps or energy-saving lamp. Energy-saving lamps typically by the lamp holder, plastic shell and internal electronic ballasts, fluorescent tubes, that is convenient for use, along with the ratio of incandescent lighting luminous efficiency of five ~ 10 times larger, the common life expectancy of in excess of six times....

The illumination range of the flood light fixtures can be adjusted freely, which makes it widely used in the production of the effect drawing. LED floodlight is LED lamp as a light source. It has characteristics of all of the LED lamp is manufacturing a lighting effect better light source LED flood light beam is highly diffuse, non directional, fuzzy contour features. The shadow of the light beam is transparent and has no hints, and the speed of light is less than the ordinary spotlight....

HQI floodlights with high luminous efficiency and good color rendering properties known and has characteristics of long life and a variety of colors to choose from, has become a favorite lighting design and application of personnel light source products, and is widely used in a variety of indoor and outdoor lighting places, such as workshop, warehouse, lobby, stadiums, an important road, park outside the building floodlighting shortcomings: but because the quartz glass anti metal halide corrosion ability is relatively weak, so HQI lamp color drift is relatively large, in light of life during this performance is particularly evident in HCI: ceramic tube metal halide lamp, belonging to hid...
