Background technique

light guide plate

Light guide plate, English light guide plate, is to use optical-grade acrylic/PC plate, and then use high-tech materials with high reflectivity and non-absorbing light, engrave with laser and V-shaped cross grid on the bottom surface of optical-grade acrylic plate , UV screen printing technology to print light guide points. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. The purpose of the reflector is to reflect the light exposed on the bottom surface back into the light guide plate to improve the efficiency of light use; under the same area of luminous brightness, the luminous efficiency is high and the power consumption is low. The single-sided microstructure array light guide plate generally adopts the production process of extrusion molding.

Common terms for lighting:

Light is a kind of electromagnetic wave, a part of the radiant energy emitted by the light source, that is, the radiant energy that can produce vision, often called "visible light". The wavelength of light: from 380nm to 780nm; the wavelength of ultraviolet rays: from 100nm to 380nm, invisible to the naked eye; the wavelength of infrared rays: from 780nm to 1mm, invisible to the naked eye.

color temperature

It is represented by the absolute temperature K, which is to heat a standard black body. When the temperature rises to a certain level, the color begins to change gradually from red-light red-orange-yellow-white-blue-white-blue. When the light color of a certain light source is the same as that of a black body at a certain temperature, we call the absolute temperature of the black body at that time the correlated color temperature of the light source.

Color rendering index

The color rendering index (Ra) is a parameter to measure the ability of the light source to show the true color of the illuminated object. The higher the color rendering index (0-100), the closer the color reproduction of the light source is to the natural primary color.

1. Color temperature and feeling

Color temperature light color atmosphere effect light source;

Fluorescent lamps and mercury lamps greater than 6500K cool, that is, bluish white and cool;

The middle of 3300-6500K is close to natural light without obvious psychological effects. Fluorescent lamps and metal halide lamps;

Less than 3300K Warm, that is, orange-yellow white with a warm feeling. Incandescent lamps and halogen lamps.

2. The effect and application of color rendering

Ra sense use

>90 Excellent Places with extremely high requirements for color identification, such as printing, printing and dyeing inspection, etc.;

80-90 very good Color TV broadcast, display lighting of exhibits;

65-80 good indoor lighting;

50-65 Moderate Outdoor lighting;

<50 Poor Places with low color requirements, such as parking lots, freight yards, etc.

Luminous flux

The unit of luminous flux is lumen Lm, which indicates how much the luminous body emits light, and the more light is emitted, the greater the number of lumens.

average life expectancy

Also known as the rated life, it refers to the number of hours when a batch of lamps are lit until half of the lamps are damaged.

light intensity

Luminous intensity is the luminous flux per unit solid angle, in candela cd.

Illumination

Illuminance is used to explain the degree of illumination on the illuminated surface, that is, the working surface. It is usually expressed by the luminous flux received per unit area, and the unit is lux lx or lumen per square meter lm/m2.

brightness

Luminance is a physical quantity used to indicate the intensity of luminous or reflective light on the surface of an object. The ratio of the luminous intensity of the luminous surface of the object in the line of sight to the projected area of the luminous surface perpendicular to this direction is called the surface brightness of the luminous surface. The unit is candela per square meter cd/m2.

Luminous efficiency

Usually referred to as light effect, it describes the quality and economical optical quantity of the light source. It reflects the amount of luminous flux radiated by the light source while consuming unit energy, that is, the ratio of the luminous flux emitted by the light source to the electrical power consumed. The unit is lumens per unit. Watt lm/w.

Beam angle

The beam angle refers to the angle of the light of the lamp, the angle of the lamp cup. Generally, there are 3 kinds of 10°, 24°, and 38°.

color appears

The color rendering index of the light source and the illuminance determine the visual clarity of the environment, and there is a balance between the illuminance and the color rendering index. The results obtained from extensive experiments are: the office illuminated with a lamp with a color rendering index Ra>90, in terms of its appearance satisfaction, is better than the office illuminated with a lamp with a low color rendering index Ra<60, and the illuminance value is higher. more than 25% higher.

light environment

Light environment is people's psychological feeling of light in a certain visual space. A good light environment gives people a good visual experience, which directly affects people's physical and mental health. When people consider creating a good light environment, they should also consider the issue of energy saving. The concept of green lighting is how to reduce the release of mercury and how to save the limited energy that human beings can survive.

Lighting type function:

Lighting fixtures consist of lighting sources, lampshades and accessories.

1. Lighting lamps are divided into decorative lamps and functional lamps according to their functions.

1. Decorative lamps are composed of decorative parts and lighting sources. In addition to proper consideration of lighting efficiency and anti-glare requirements, they mainly meet the needs of architectural art with beautiful appearance.

2. The function of functional lamps is to redistribute the luminous flux of the light source, improve the utilization efficiency of light and avoid glare, and create a suitable light environment. For special lamps used in humid, corrosive, explosive, flammable and other environments, the lampshade also functions as isolation protection.

2. Lighting lamps are divided into indoor lighting lamps and outdoor lighting lamps according to the place of use.

1. Indoor lighting fixtures are usually classified according to the distribution ratio of the total luminous flux in the upper and lower hemispheres of the space. Accordingly, the International Commission on Illumination suggested that lighting fixtures be divided into five types: direct, semi-direct, evenly diffused, semi-indirect, and indirect.

2. Outdoor lighting fixtures, mainly floodlights. Floodlights, also known as light projectors, use reflectors, transmissive mirrors and grilles to constrain light within a small solid angle to become a strong light source. They are often used for night lighting of large buildings.

Basic features of lighting:

The basic characteristics of lighting fixtures are usually expressed by three indicators: light distribution curve, ie light intensity distribution curve, protection angle and efficiency.

1. Light distribution curve. When the lamp is in working state, the luminous intensity vector in all directions is drawn on the three-dimensional coordinates of X, Y, and Z according to a certain proportion, and then the vector terminals are connected to form a closed light intensity body. When the light intensity body is cut by a plane passing through the axis, a closed intersection line is obtained on the plane, and the intersection line is drawn on the plan in the form of polar coordinates to become the light distribution curve of the lamp. The light distribution curve is usually drawn according to the luminous flux emitted by the light source as 1000 lumens.

2. Protect the corner. When the brightness of the light source exceeds 16×103 canm/m2, the human eye cannot bear it, and the brightness of the filament of a 100-watt incandescent lamp is as high as 300×103 canm/m2. In order to reduce or eliminate the glare caused by this high-brightness surface, adding a lampshade made of an opaque material to the light source can have a significant effect. The range of glare prevention of lighting fixtures is often measured by the protection angle γ, which refers to the angle between the line connecting the edge of the lampshade and the edge of the illuminant and the horizontal plane. The lampshade made of translucent material has a certain brightness, even if it has a certain protection angle, it can still cause glare, so the brightness of the lampshade surface should be limited.

3. Efficiency. The lampshade made of any material will absorb part of the luminous flux, and the light source itself will also absorb a small amount of reflected light, that is, the reflected light on the inner surface of the lampshade. Subtracting these luminous fluxes is the luminous flux projected by the lighting fixture to the space. Usually the ratio of the luminous flux emitted by the lighting fixture to the luminous flux of the light source indicates the efficiency of the lighting fixture.
