There are 5 main components of the courtyard lamp

2015-08-22

  The courtyard lamp is mainly composed of five components, namely:

  1. light source,

Illuminant is the main component of all illume product, according to different illuminance requirement, can choose different brand, different type illuminant, commonly used illuminant has: incandescent lamp, energy-saving lamp, fluorescent lamp, sodium lamp, metal halide lamp, ceramic metal halide lamp, and new-style LED illuminant.Characteristics of each light source:

1. The incandescent light bulb

Incandescent emission refers to the visible photoelectric radiation produced by an atom excited by heat.Incandescent lamps use the principle of incandescence, which allows an electric current to pass through a tungsten filament in a vacuum, heating it up to incandescent and emitting visible light.The color temperature of ordinary incandescent lamp is 2800K, which is yellow and warm compared with the natural light color.The advantage and disadvantage of incandescent lamp: it is cost is low, use and installation are simple and convenient.Suitable for frequent open, off the performance of the lamp and the impact of life are very low.

Advantages and disadvantages of incandescent lamps:

Short life, low luminous efficiency.The visible light emitted by incandescent lamps is generally less than 10% of electric energy. Most of the energy is converted into infrared radiation, which generates a lot of heat.In addition, the ultraviolet radiation that incandescent lamp gives out is higher also, can cause the discoloration of illuminate article.

2. Fluorescent lamp and energy-saving lamp

Fluorescent lamp, energy-saving lamp is a low-pressure mercury vapor arc discharge lamp, usually a long tube, two ends have an electrode.The lamp contains a low-pressure mercury vapor and a small amount of inert gas. The inner surface of the tube is coated with a phosphor layer.Fluorescent lamp is divided into straight fluorescent lamp and compact fluorescent lamp.Straight tube fluorescent lamp can be divided into preheating start, fast start and instantaneous start by means of starting, and can be divided into T12, T8 and T5 by means of light tube.Compact fluorescent lamps (CFLS) have been developed to replace incandescent lamps which consume a lot of electricity.Conventional incandescent bulbs have a life span of only 1,000 hours, while compact fluorescent bulbs typically have a life span of 8,000 to 10,000 hours.

Advantages and disadvantages of fluorescent lamp and energy-saving lamp:

The main advantage of fluorescent lamps is their high luminous efficiency. The visible light emitted by a typical fluorescent lamp is equivalent to about 28% of the energy input.The geometry of the tube, the filling gas and pressure, the phosphor coating, the manufacturing process, the ambient temperature and the frequency of the power supply all affect the luminous efficiency of the fluorescent lamp.The color of the light that fluorescent lamp gives out is decided largely by the phosphor that besmears the surface inside lamp tube.The color temperature of different fluorescent lamps varies widely, from 2900K to 10000K.According to the color can be roughly divided into warm white (WW), white (W), cold white (CW), daylight color (D) several.Under normal circumstances, warm white (WW), white (W) and daylight (D) fluorescent lamps have general chromogenic properties, cold white (CW), soft white and advanced warm white (WWX) fluorescent lamps can provide better chromogenic properties, and advanced cold white (CWX) fluorescent lamps can have excellent chromogenic properties.The light that fluorescent lamp gives out is more dispersive, not easy focus, because this is used at more downy illume, be like, shoot floodlight illume on, working illume, downy key illume.

3. Sodium lamp

Also known as high - pressure sodium lamp is the discharge lamp by sodium vapor discharge.Luminous efficiency is especially high, long life, good adaptability to the environment, all kinds of temperature conditions can work normally.

Advantages and disadvantages of sodium lamp:

Sodium lamp specification and size large;Light chromatic aberration, is a kind of uncomfortable yellow and white cold light;Chromogenic poor, ordinary high pressure sodium lamp chromogenic index only 23. Therefore, ordinary high pressure sodium lamp mostly used in road lighting and other luminous efficiency and life requirements, and the light color and chromogenic requirements are not high in the field.At present, there is a class of improved high chromogenic high-pressure sodium lamp, with warm white light color, chromogenic index can reach more than 80% of the high chromogenic.This kind of lamp can be used to show lighting field, energy-saving effect is obvious.

4. The metal halide lamp

Metal halogen lamp, also known as metal halogen lamp, is a kind of high-pressure gas discharge lamp. Its basic structure is a transparent glass shell and a high-temperature quartz glass arc tube. Between the shell and the inner tube, nitrogen or inert gas is flushed, and the inner tube is filled with inert gas, mercury vapor and metal halide.The basic working principle of metal halide lamp: enter the work state, metal halide vapor diffusion to the arc arc heart, under high temperature is dispersed into metal and halogen atoms, the metal atoms emit visible light, to participate in discharge when the metal atoms and halogen atom diffusion to electrical isolated tube outer wall area, the composite metal halide.

Advantages and disadvantages of metal halogen lamps:

Metal halogen lamp is the biggest advantage of luminous efficiency, long life.Due to the different structure of the lamp body and the filled metal halide, the luminescence efficiency, the color temperature of the light and the chromogenic property of the metal halide lamp vary greatly.Poor metal halogen lamp although luminous efficiency is high, but poor color;The light color that good metal halogen lamp gives out is close to the white of natural light, visual perception feels comfortable, show color sex better also.Metal halogen lamps do not work immediately and take about 5 minutes to warm up to full brightness output.After a power outage, it takes 5-20 minutes to cool the bulb before restarting.Metal halogen lamps are sensitive to fluctuations in the voltage of the power supply. Changes in light color occur when the voltage of the power supply changes by more than 10% up or down the rated value.And different working position also can affect the color of the light and the life of the lamp.

5. Ceramic metal halogen lamps

Ceramic metal halogen lamp is the metal halogen lamp that USES translucent ceramic to serve as electric arc tube, it is the ceramic technology that combines quartz metal halogen lamp and sodium lamp together, collect the advantage of both at a body newer and high grade illuminant.

Advantages and disadvantages of ceramic metal halogen lamps:

Due to the ceramic tube can withstand higher temperature, the chemical properties are very stable, so the ceramic metal halogen lamps have the advantages of higher luminous efficiency, long life, more stable color, small size, excellent color rendering, Ra>80.And ceramic tubes can filter out most of the uv radiation, reducing the fading of objects due to lighting.In view of these advantages, ceramic metal halogen lamps are becoming an important light source to display the efficiency of light design.

6. LED

Also known as LED, or LED, is a new type of light source that directly converts electrical energy into visible light by using field emission principle through semiconductor diode.Field luminescence refers to the phenomenon of luminescence due to the interaction between an appropriate substance and an electric field.

Advantages and disadvantages of LED leds:

As a new type of semiconductor light source, led has the following advantages compared with traditional light source: long life, up to 100000 hours of light;The startup time is short, and the response time is only tens of nanoseconds.Strong structure, as a solid solid structure, can withstand strong vibration and impact;Luminous efficiency is high, energy consumption is small, is an energy saving light source;The luminous body is close to the point light source, and the radiation model of the light source is simple, which is beneficial to the design of lamps and lanterns.Luminescent directivity is very strong, do not need to use reflector to control the direction of light exposure, can be made into thin lamps, suitable for the occasion that does not have much installation space.Generally speaking, led is the fourth generation of light source after incandescent lamp, fluorescent lamp and high voltage discharge lamp.With the development of new materials and manufacturing technology, the performance of leds is improving and the applications are becoming more and more extensive.
