The personal safety of the lighting system such as personal safety of the lighting system mainly includes the safety of the hanging system, the safety of the lamps and bulbs, and the prevention of electric shock, burns and drops. A variety of lamps and hangers are hung above the security studio of the hanging system. Usually, several to dozens of spotlights, backlights, downlights, computer lights, etc. are suspended on the boom, and the weight of the lamps and the like is to be measured. To determine the load that the boom and motor can withstand. When designing the equipment layer, calculate the total weight of the luminaire and the sling according to the lamp position map designed by the studio, calculate the total weight that the equipment layer should be able to bear, and the weight that should be borne per square meter. In the design of the building, the weight of the equipment layer and the weight of the luminaire to be hanged, the height of the equipment layer from the ground, and the height above the equipment layer should be considered.
In addition to preventing the loss of lamps and boom lights, the heat and safety of the lamps should also pay attention to the heat of the lamps, the heat dissipation of the lamps and bulbs, and whether they will burst. In the past, we used ordinary downlight bulbs in the downlights, which were often easy to burst, and the glass fragments were easy to fall onto the carpet or the actors. When dropped onto the carpet, the carpet could be burned. Later, we switched to the PAR bulb, which has a reflective bowl and glass case on the outside of the bulb to avoid the phenomenon of blasting, effectively preventing the glass from hurting people, and the life of the bulb is longer than before.
In actual use, we must consider the heat of the luminaire. The distance between the luminaire and the nearest curtain should be greater than 0.5m. At the same time, be careful not to let other flammable materials close to the luminaire. Regularly check the silicon box, power cord, power distribution cabinet for problems, how to heat, and arrange for personnel to conduct systematic safety inspections during large-scale performances. Grounding should be done safely for the lighting system. Use lamps and connectors with grounding wire. When replacing the lamp, turn off the power or unplug the plug from the boom or luminaire to prevent electric shock.
An Indoor Access Point is a device for wireless local area networks (WLAN) that provides wireless network coverage and connectivity. It can connect to a wired network and transmit data via a wireless signal, allowing users to connect to the network wirelessly within coverage.
Indoor access points come in a variety of different types and specifications to suit different scenarios and needs. Here are some common types of indoor access points:
1. Single Band Access Point: A single band access point operates in the 2.4GHz band and typically provides a maximum transfer rate of 300Mbps. This type of access point is suitable for small office or home networks because the 2.4GHz band has better penetration and coverage, but a relatively low transfer rate.
2. Dual Band Access Point: The dual band access point supports both 2.4GHz and 5GHz bands, providing higher transmission rates and better performance. The 5GHz band has more interference free channels than the 2.4GHz band, which can provide faster speeds and more stable connections. Dual-frequency access points are suitable for medium sized offices, malls or hotels.
3. Lightweight Access Point: A lightweight access point is a wireless network device that needs to be used with a network controller. Lightweight access points do not have independent management functions themselves, but are centrally managed and configured via a network controller. This type of access point is suitable for large enterprises or organizations to enable centralized management and monitoring of the entire network.
4. Standalone Access Point: A standalone access point is a standalone device that has its own management and configuration functions and does not require additional network controllers. This type of access point is suitable for small businesses or individual users and can provide a simple and easy-to-use wireless networking solution.
5. Scalable Access Point: A scalable access point is a device that can scale on demand, increasing or decreasing the number of access points based on network demand. This type of access point is suitable for places that require flexible scaling, such as large office buildings, schools, or hospitals.
In addition to the types listed above, there are some special purpose indoor access points, such as:
1. Wall-mounted Access Point: A wall-mounted access point can be plugged directly into a Wall power outlet without the need for an additional power cord. This type of access point is suitable for home networks or small offices and can provide easy installation and use.
2. Integrated Antenna Access Point: The antenna of the antenna access point is integrated into the device, and no additional antenna installation is required. This type of access point is suitable for sites that require simple installation and a nice look.
3. Multiple Antenna Access Point: Multiple antenna access points can achieve better signal coverage and performance through multiple antennas. This type of access point is suitable for large venues or high-density user environments, such as conference rooms, stadiums or airports.
To sum up, there are many different types and specifications of indoor access points, which can be selected according to different scenarios and needs. Whether it's a small office, home network or a large enterprise, you can achieve convenient wireless network coverage and connectivity through indoor access points.
