First, the halogen camera infrared camera that has been eliminated: The halogen lamp has very strong luminous power. Of course, the power consumption and heat generation will be relatively large, and the cost is relatively high. Its fatal disadvantage is its bulkiness, insufficient heat dissipation, and very short life span. Generally within a thousand hours, and the red storm phenomenon is particularly serious, it is not suitable for civilian night vision surveillance. Halogen Infrared Cameras have large power and have optical and thermal conversion of filters. Therefore, the problem of heat generation is particularly serious. The maintenance cost is high and the service life is short.
Second, LED infrared camera: LED infrared light is composed of a certain number of infrared light emitting diodes. Infrared Emitting Diode A PN junction is made of a material with high infrared radiation efficiency (common GaAs GaAs). A forward bias voltage is applied to the PN junction to inject infrared light. The spectral power distribution is center wavelength of 830 to 950 nm, and the half-peak bandwidth About 40nm or so, it is a narrowband distribution, which is a range that can be sensed by a CCD camera. LED infrared cameras are generally suitable for medium and short distances of 10 to 100 meters, and have the highest market share. However, there is a problem of non-uniform illumination. They are mainly suitable for corridors, halls, warehouses and other interior and exterior buildings, community perimeters, roads, etc. monitor.
Third, the LED array infrared camera: The core of the array infrared lamp is an LED array. Compared with the traditional LED, the LED array has the following advantages: 1. The brightness is high, the output of a single LEDArray is about 1W-30W, and the brightness is about It is tens of times of the output of conventional single LED 5~15mW, so the range is far away; 2. The efficiency of electro-optical conversion is high, the electro-optic conversion efficiency of ordinary infrared LED is only about 10%, while the efficiency of electro-optical conversion of LEDArray is improved to 25%. Left and right; 3, small size, LEDArray technology will be highly integrated lighting unit, under the same brightness indicators than ordinary LED infrared light product size is much smaller; 4, long life, LEDArray's life is 50,000h, much higher than the average LED life . Array infrared lamp products have a clear deficiency, namely "eccentricity." Since the light emitting angle can reach 120-180 degrees, it is necessary to reduce the light transmission angle through the lens to match the camera lens. This inevitably causes a lot of light to deviate from the center of the lens, resulting in poor light transmission efficiency. The application scope of the LED array infrared camera is basically the same as that of the LED infrared camera, and is more suitable for short-distance monitoring applications such as indoor and building exteriors, community perimeters, and roads in halls and warehouses.
Fourth, dot matrix infrared cameras use dot matrix infrared light sources. The third-generation infrared light-emitting components used in dot-matrix infrared lamps are based on the second-generation product, the array-based infrared (LED--Array), and are also called second-generation LED-Arrays. Compared with the first generation, the second-generation LED-Array has the advantages of small size, good heat dissipation, low attenuation, long life, and a rated life of 50,000 hours. The dot matrix infrared lamp is also called high-power array infrared. The biggest difference from the low-power array infrared is higher brightness and lower cost, and through the independent lens, the light distribution angle can be arbitrarily adjusted according to the use demand, so that it can be solved simultaneously. The first generation of "flashlight effects" and the second generation of "eccentricity."
Fifth, laser infrared camera: laser infrared camera irradiation distance is generally up to 300 to 5000 meters, due to energy concentration, the angle is not close to the short distance, the current cost is still high. It is more suitable for the monitoring of forest fire prevention, oil fields, railways, water conservancy, scenic spots, military, aquaculture, ports, and security markets. With the further reduction of costs, it has been applied to many areas that require night vision surveillance including the community. . Therefore, infrared cameras need to determine the type of camera according to the specific use environment, especially the night environment.
Interior & floor tiles
First, according to the space classification:
Kitchen Tiles, Living Room Tiles, Restaurant Tiles, Balcony Tiles, Bathroom Tiles, Study Tiles, Bedroom Tiles, Wall Tiles, Stairs Tiles
Second, according to the function classification:
Anti-skid tiles, wear-resistant tiles, anti-fouling tiles, anion tiles, electrostatic tiles, high strength tiles, permeable tiles, waterproof tiles, antifreeze tiles
Third, in accordance with the production process points:
There are mainly glazed tiles, unglazed tiles, whole body tiles, polished tiles
Glazed tiles: the body surface to impose zirconium white glaze, glaze protection, transparent glaze glaze medium ceramic tiles;
Unglazed brick: the body surface does not impose various types of glaze, directly naked ceramic tile burning;
Full-body brick: ceramic tile body through the fabric, seepage and other technology coloring glazed brick and unglazed brick
Polished: refers to the surface of the tile after a polished brick process.
Fourth, the main tile category commentary
1 Full cast glaze tile
Full cast glaze tile is a glaze polishing process can be a special formula glaze, which is applied to the last of the antique brick glaze, the current general transparent glaze or transparent convex glaze, applied to the all-thrown Glaze full throw glaze set of polished brick and antique brick advantages in one.
Glazed polished glazed tiles as smooth as bright as polished, at the same time glazed colors such as antique brick-like pattern rich, thick colors or brilliant. Touch by hand, the surface light and soft, smooth does not protrude, appears crystal clear, underglaze stone texture clear and natural, and the upper transparent glaze fusion, like a layer of transparent crystal glaze film covering, making the overall level more three-dimensional clarity.
Full cast glazed tile surface as long as there is about 0.5-1mm glaze layer on it. The polished brick also 2-3mm of fine material; polishing glaze pattern simulation is easy to do, the cost is low. Full cast glaze tile production more environmentally friendly, glazed layer firing faster, lower energy consumption, glaze polishing than the lower energy consumption and higher yields. Glazing after the ultra-flat glaze and other products, is the full cast glaze product upgrades.
2 ceramic stone
In the line known as ceramic glass ceramic composite board, is a layer of 3-5mm glass-ceramic composite ceramic vitrified surface, after the second sintering completely integrated into high-tech products, in simple terms, microcrystalline Stone and other ceramic tile products is the biggest difference between the surface layer of glass-ceramic.
Microcrystalline stone tile, as a polished brick, antique tile after another of the most attractive new category, also known as micro-ceramic stone micro-jade, jade spar, etc.;
3 Rustic porcelain tile
Antique tiles is a kind of glazed ceramic tile. The embryo body is made of porcelain (about 3% of water absorption) or quality (about 8% of water absorption). It is used for building wall and floor. Because of the color and texture, it is similar to stone veneer After a long time, the industry generally referred to as antique brick.
Antique brick is not a product of China's building ceramics industry, is imported from abroad. Antique brick is evolved from the color glazed tiles, in essence, glazed porcelain tiles. Compared with ordinary glazed tiles, the difference is mainly reflected in the glaze color above.
4 polished tiles
Polished brick is the surface of the whole body of brick polished by a bright brick, is a kind of whole body brick. Relative to the whole brick, the polished surface to be much more smooth.
Hard wear-resistant polished tiles, suitable for use in the toilet, kitchen and other interior space. In the use of seepage technology, based on the polished tiles can make a variety of Faux Stone Tiles, faux beick tiles effect.
Polished tiles are also divided into seepage-type polished tiles, micro-brick (superfine powder), multi-tube fabric, ceramic stone, anti-static polishing brick and other categories.
Wood grain brick is a kind of surface appearance of Wood Grain decorative patterns of new environmentally friendly building materials. Sub-original edge (when firing is a long strip, without cutting) and hardcover side (brick, post-cut paving) two categories, each with advantages and disadvantages.
Wood grain brick refers to the surface with natural wood texture pattern decorative ceramic tiles, divided into two kinds of glazed tiles and split brick. The former is through the screen printing process or paste ceramic paper flowers to make the product surface grainy pattern, while the latter is the use of two or more different colors were burned in the billet with a vacuum screw extruder spiral mixing After the cut through the mouth of the formation of the wood-like texture of its usual block of products split brick.
With the improvement of technology, wood grain brick products have matured, according to the surface gloss division, in addition to the traditional matte wood bricks, but also can be divided into bright wood grain bricks (full cast glaze wood bricks), soft light Wood grain brick.
