The light emitted from the lamp is absorbed by the optical acrylic plate and stays on the surface of the optical acrylic plate, when the light rays are emitted to each light guide point, the reflected light can be diffused towards each angle, and then the reflection condition is destroyed and emitted from the front surface of the light guide plate. The light guide plate can uniformly emit light through various light guide points with different densities and sizes. The reflector plate is used for reflecting the light exposed from the bottom surface back to the light guide plate so as to improve the use efficiency of the light; under the condition of 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 a manufacturing process of extrusion molding.

Lighting lamp is commonly used in terms of:
light is an electromagnetic wave, and a portion of the radiant energy emitted by a light source, i.e., radiant energy that produces vision, is often referred to as "visible light". Wavelength of light: from 380nm to 780nm; wavelength of ultraviolet light: from 100nm to 380nm, the glass is invisible to the naked eye; wavelength of infrared ray: from 780 nm-1 mm, no visual effect is seen.
Color temperature
The absolute temperature K is expressed by heating a standard black body, when the temperature rises to a certain extent, the color starts to gradually change from red-light red-orange-white-blue, and when the light color of a certain light source is the same as the light color of the black body at a certain temperature by utilizing the characteristic of the light color change, we refer to the absolute temperature of the black body at that time as the correlated color temperature of the light source.
Color rendering index
The color rendering index (Ra) is a parameter that measures the ability of a light source to appear the true color of an illuminated object, and the higher the color rendering index (0-100), the closer the reproduction of the color by the light source is to the natural primary color.
1. Color temperature and feel
A color temperature light color atmosphere effect light source;
a cool and refreshing sense fluorescent lamp with blue color and white cool and mercury lamp with more than 6500K;
the middle of 3300-6500K is close to natural light, and a fluorescent lamp and a metal halogen lamp have no obvious psychological effect;
less than 3300K warmth, i.e., orange white warmth, perceived incandescent, halogen lamp cups.
2. Effect of color development and use thereof
Ra sensory use
90 places with extremely high requirements on color identification, such as printing, printing and dyeing product inspection and the like;
80-90 good color television rebroadcast and display exhibit illumination;
65-80 better indoor illumination;
50-65 medium outdoor lighting;
<50 worse places with low color requirements, such as parking lots, freight yards, etc.
Luminous flux
The luminous flux unit is lumen Lm, which indicates how much the illuminant emits light, and the more the light is emitted, the larger the lumen number is.
Average life span
Also referred to as rated life, it refers to the number of hours that a batch of lamps is lit to half the number of damaged non-lit lamps.
Light intensity
The light intensity is the luminous flux in candela cd per solid angle.
Illuminance level
Illuminance is used to describe the degree to which the surface being illuminated, i.e., the working surface, is illuminated, typically expressed in terms of the received luminous flux per unit area, in luxlx or lumens per square meter lm/m2.
Brightness of light
The brightness is a physical quantity used for representing the intensity of light emission or light reflection on the surface of an object, and the ratio of the light emission intensity of the light emitting surface of the object in the direction of the line of sight to the projection area of the light emitting surface in the direction perpendicular to the direction is called the surface brightness of the light emitting surface, and the unit is candela per square meter cd/m2.
Luminous efficiency
Often referred to simply as light efficiency, describes the quality and economical optical quantity of a light source, which reflects how much light source emits a luminous flux while consuming a unit of energy, i.e. the ratio of the luminous flux emitted by the light source to the electrical power consumed, in lumens per watt lm/w.
Angle of beam
The beam angle refers to the angle of the light of the lamp and the angle of the lamp cup. There are generally 3 kinds of the materials of 10 °, 24 °, and 38 °.
Color appearance
The color rendering index of the light source, together with the illuminance, determines the visual clarity of the environment, there being a trade-off between illuminance and color rendering index. The results obtained from extensive experiments were: an office illuminated with a lamp having a color rendering index Ra >90 has an illuminance value that is 25% or more higher than an office illuminated with a lamp Ra <60 having a lower color rendering index in terms of the degree of satisfaction of the appearance.
Light environment
The light environment is psychological perception of light by people in a certain visual space. A good light environment gives people a good visual feeling, and the good visual feeling directly affects the physical and mental health of people. People consider energy conservation while considering creating a good light environment. The concept of green lighting is how to reduce the release of mercury and save the limited energy for human survival.
Lighting lamp type function:
the lighting lamp consists of a lighting source, a lampshade and accessories.
1. The lighting lamps are divided into two types according to functions, namely decorative lamps and functional lamps.
1. The decorative lamp is formed by combining decorative components and illumination light sources, and mainly meets the requirements of architectural art by attractive appearance besides properly considering the requirements of illumination efficiency, glare prevention and the like.
2. The function lamp has the following functions: the luminous flux of the light source is redistributed, the light utilization efficiency is improved, glare is avoided, and a proper light environment is created. The lampshade of the special lamp used in humid, corrosive, explosive, inflammable and other environments has the isolation and protection functions.
2. The lighting lamps are classified into indoor lighting lamps and outdoor lighting lamps according to the use places.
1. Indoor lighting fixtures are generally classified according to the distribution ratio of total light flux in the upper hemisphere and the lower hemisphere of the space. The international commission on illumination suggests accordingly: the lighting lamp is divided into direct, semi-direct, uniform diffusion, semi-indirect and indirect.
2. The outdoor lighting lamp is mainly a floodlight. Floodlights, also known as projectors, use mirrors, transmissive mirrors and gratings to confine light to a small solid angle to form a strong light source, often used for night scene lighting in large buildings.
Basic characteristics of the lighting lamp:
the basic characteristics of the lighting lamp are generally represented by light distribution curves, namely light intensity distribution curves, protection angles and efficiency.
1. And (3) a light distribution curve. When the lamp is in working state, the luminous intensity vectors of all directions are drawn on X, Y, Z three-dimensional space coordinates according to a certain proportion, and then vector terminals are connected to form a closed luminous 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 a plane graph in a polar coordinate mode to form a light distribution curve of the lamp. The light distribution curve is typically plotted with a luminous flux of 1000 lumens emitted by the light source.
2. And protecting the corners. When the brightness of the light source exceeds 16×103 candela/m 2, the human eye cannot tolerate it, whereas the filament brightness of a 100 watt incandescent lamp is as high as 300×103 candela/m 2. In order to reduce or eliminate glare caused by such high brightness surfaces, a light cover made of an opaque material is added to the light source to achieve a significant effect. The glare-preventing range of the lighting lamp is measured by a common protection angle gamma, which refers to an included angle between a connecting line of the edge of the lamp shade and the edge of the illuminant and the horizontal plane. The lampshade made of semitransparent materials has certain brightness, and even if the lampshade has a certain protection angle, the lampshade can still cause glare, so that the brightness of the surface of the lampshade is limited.
3. Efficiency is improved. The lamp shade made of any material can absorb a part of luminous flux, the light source can also absorb a small amount of reflected light, namely the reflected light of the inner surface of the lamp shade, and the luminous flux is subtracted from the luminous flux, so that the luminous flux projected to a space by the lighting lamp. The efficiency of a lighting fixture is typically expressed in terms of the ratio of the light flux emitted by the lighting fixture to the light flux of the light source.
