LED light classification

1.street light

Street lamps are lamps that provide lighting functions for roads. Its key feature is that it has a light distribution type suitable for road lighting, and its appearance has nothing to do with classification. Although it is often used in combination with light poles, street lights only refer to light-emitting appliances and do not include light poles and other components. Therefore, the suspension cable lamp that does not require a lamp pole as an installation carrier also belongs to the category of street lamps. Street lamps are high-level lighting fixtures. Different road types require different light distributions to match to solve key problems such as road brightness/illuminance, brightness/illuminance uniformity, longitudinal uniformity, glare and so on. Because of its strong controllability and intelligent brightness adjustment, LED street lights can replace HID with good energy-saving effects. Like other outdoor lamps, street lamps require a higher degree of protection.

2. tunnel lights

Tunnel lights refer to special lamps used for tunnel lighting in order to solve a series of visual problems that appear when vehicles enter, pass and exit the tunnel. Tunnel lights are usually separated along the tunnel, and the installation methods include ceiling-mounted, wall-mounted, and boom-type. At the entrance, transition section, middle section and exit section of the tunnel, brightness, uniformity, glare, stroboscopic and other factors need to be considered for lighting arrangement and power distribution. The tunnel light needs to have strong shock resistance, dustproof and waterproof shell, corrosion resistance and rust resistance.

3.floodlight

Floodlight is a kind of functional lighting fixture, which emits a uniform beam with weak directivity, and the beam angle is generally a wide beam. When irradiating objects, the weakening speed of light and darkness is very slow, and whether it can produce soft and transparent lighting effects, it is widely used in outdoor billboards, bridges and culverts, squares, buildings and other places. The shape of the lamp body is usually flat and square, and it is required to have a higher degree of protection like all outdoor lamps. At least it should be able to protect the lamp junction box against dust and water spray. The light source cavity can protect against dust, water spray and dripping.

4. projecting light

projecting light is a kind of functional lighting fixture, which emits a beam with strong directivity and a clear outline of the light beam. The beam angle is generally a narrow beam. When irradiating objects, the light and shade weaken faster, and whether it can produce a strong contrast lighting effect, it is widely used in outdoor plastic sculptures, bridge suspension cables, building pillars and other places. The shape of the lamp body is usually in the shape of a deep cone column. Like all outdoor lamps, a higher degree of protection is required. At the minimum, it should be able to protect the lamp junction box against dust and water spray. The light source cavity can protect against dust, water spray and dripping.

5. garden lamp

Garden lamps usually refer to vertical lamps with integrated design of lamp poles and luminous bodies. The height of the lamp body is generally about 2-6 meters, which is a medium-level lighting lamp. An independent floodlight is installed on a general pole, which is not usually considered a garden light. Garden lights can be functional lighting fixtures that provide precise lighting value, and their light-emitting parts have a specific light distribution; they can also be decorative lights that provide aesthetic value, and their light-emitting parts are often in a diffuse form. Among them, the cylindrical shape is also called Landscape lamppost. Some lighting fixtures similar to garden lights are often called light sculptures due to their complex shapes and extremely individualized shapes. Strictly speaking, light sculptures cannot be used as garden lights, but their codes are still prefixed with the classification codes of garden lights.

6. lawn lamp

Lawn lights usually refer to vertical luminaires with an integrated design of light poles and luminous bodies. The height of the lamp body is generally about 0.3-1.2 meters, which is a low-level lighting luminaire. Similar to garden lights, lawn lights also have functional lighting and decorative lighting. Among them, the glare control of the lawn lamp for functional lighting purposes is quite strict. It has a structural similarity with the courtyard lamp, but the volume is small. Although the height of some lamps is between 0.3-1.2 meters, the shape is completely personalized and quite complicated. We often call them light pieces. Strictly speaking, lighting sketches cannot be used as lawn lamp products, but their code is still prefixed with the classification code of lawn lamps.

7.floor Lamp

The height of the floor lamp is generally less than 0.3 meters, but it must protrude above the installation surface, which is a low-level lighting fixture. It is generally used in conjunction with garden lights and lawn lights, and is often installed in park paths, green lawns, and surrounding squares to serve as a starting point for decoration. Floor lights, like all outdoor lights, have a higher level of protection, and can at least protect against splashes and dust particles.

8.buried lamp

Buried lamp are low-level lighting fixtures whose main body is embedded under the installation surface. They are used for outdoor or indoor directional lighting or accent lighting. They are also called underground uplights. Their light intensity distribution curves can be symmetrical or asymmetrical. of. Outdoor buried lights must be able to withstand the weight of people and vehicles, and have a high degree of protection. Because outdoor buried lights are installed in the soil or embedded in gravel, the lights need to ensure sufficient drainage capacity. Buried lights generally use high-strength cast aluminum housing. Indoor underground lights do not require high levels of protection and load-bearing capacity, but they still need to be clean, mopping the floor, and pedestrians do not cause damage to the lights. Limited by the building structure, the height of indoor buried lights should be as thin as possible. The surface of the buried lamp body in this definition does not carry any characteristic meaning patterns or marks.

9.clearance light

Contour lights are mainly used for building borders and landscaping. They are usually used outdoors. The shape of the lamp body is linear, which has high requirements for waterproofing. Generally, it is equipped with a control system that can present different lighting effects according to a certain program. The key feature is that the lamp itself is a part of the look and feel. If the lamp aims to illuminate the object, it is not classified as a contour lamp. Also called guardrail tube, digital tube, etc.

10.linear wall washer

The linear wall washer is mainly used for architectural decoration lighting. It evenly washes the facade or inner wall of the building. It is generally a long strip. Its key feature is that the light distribution meets the wall washing requirements and can be embedded or peripheral. Controlling changes in color and brightness. It is generally installed in a trench or slit in a building, requiring easy installation, convenient splicing between lamps, continuous light spot, and small lateral volume. The outdoor linear wall washer is the same as other outdoor lamps, and requires a higher degree of protection.

11.underwater lamp

Underwater lights refer to lights that work underwater and are mostly used for pool landscape lighting. Because it has been working in water for a long time, its dustproof and waterproof grade needs to reach the IP68 specification, and the electrical protection grade needs to reach the Class III standard. The safety and reliability requirements are high. Usually, safety and reliability are guaranteed by the ultra-low safety voltage of 12v. At the same time, independent or integrated transformers or converters need to be installed on the water. Only flexible rubber insulated cables can be used for power supply lines. The installation of the luminaire must ensure that the maximum allowable depth is not exceeded. Under the condition that the operation in an anhydrous environment is not clearly allowed, the underwater light can only be operated under water. Lighting engineers should follow the corresponding special safety rules to install and operate such special lamps.
