The Working Principle And Application Of Omni-Light Lamp

Jun 15, 2017

The traditional electric light source whether is the incandescent lamp or the high, low pressure gas discharge lamp, is consists of a glass shells and a filament, the electricity transforms into the light energy through the filament into the lamp. The floodlight is by the high-frequency electromagnetic can be coupled to the light bulb induction, so that the gas inside the bulb to form a plasma avalanche ionization, the plasma stimulated atoms return to the ground state when the spontaneous emission of 245nma of ultraviolet light, the inner wall of the fluorescent lamp stimulated by ultraviolet light. Floodlight is a new type of electric light source which is based on the familiar principle of the gas discharge and high-frequency electromagnetic induction of fluorescent lamp. Since it does not have the necessary filament or electrode of conventional electric light source, it is also called electrodeless lamp; the operating frequency of low voltage gas discharge high-frequency electrodeless lamp is usually 2.5 3.0MHz, that is to say, the working frequency of floodlights is about 250 times times higher than that of ordinary incandescent lamps and the daily use of inductive fluorescent lamps, metal halide lamps, high pressure sodium lamps, etc. (50HZ), which is 50,000 ~ 60,000 times times more than the working frequency (30) of ordinary energy-saving lamps or electronic ballasts.

Practical application

Floodlight is a global lighting point light source, light to all directions, no clear target, often used as auxiliary light, ambient light floodlight main has the following: multiplier default value of 1, when greater than 1 o'clock, when the intensity of the light increases, when it is negative, the light is sucked, and the light is sucked from the surface of the illuminated object: Adjust the contrast between the high light and the transition area soften coefficient: The boundary attenuation parameter between the softening transition area and the shaded area:

Near-range attenuation: Start: Invisible start position end: Invisible ending position, fully visible start position use: Set show with attenuation; display the attenuation range of a light source in a view with a long distance attenuation: Start: Visible start position end: visible ending position the greater the distance between the floodlight and the object, and the greater the angle of the object, the greater the intensity, the greater the floodlight and the object, the smaller the angle of the object, and the smaller the intensity.
