CHZ lighting case | smart lighting Perfect implementation of DALI control office lighting project
Recently, the Spanish branch of CHZ Lighting implemented a large-scale office lighting project in an office building in Bilbao, replacing the traditional fluorescent grid lights with panel lights and the traditional switching method with an intelligent DALI system; precise control of each panel Lights, keep abreast of the power consumption and working status of each group of lights; at the same time realize the dimming function of the panel lights to achieve the greatest energy saving effect. DALI is a communication digital addressable interface bus protocol specially used for lighting control, which defines the communication protocol between the driving power supply and the controller. In modern lighting control, the superiority of digital addressing ability realizes the separation of the main control circuit, that is, when the main power circuit changes, the control circuit remains unchanged, and a certain or a group of lamps can be controlled individually. The reliability of the DALI bus is significantl
Q: What is DALI?
A: DALI is the acronym for "Digital Addressable Lighting Interface", which translates as "Digital Addressable Lighting Interface". It is the internationally open lighting control communication protocol IEC62386, which specifies the digital communication control method between electronic ballasts, control units and various sensors. That is to say, DALI is a protocol specially used for lighting control. It can control each lamp individually, realize the control of brightness, color temperature, color, etc., control the lamps in groups, and set different scenes.

Q: How to reduce the sensing distance on the back of the radar module?
A: 1) Under normal circumstances, after the antenna form is fixed, the pattern is basically determined, and the antenna back lobe optimization can consider the use of a more directional antenna; 2) When designing the antenna: Keep the antenna surface away from the edge of the board as much as possible, increase the size of the board as much as possible, and spread the ground on the bottom as much as possible. Consider placing a shielding cover on the back of the module to reduce the radiation effect of the antenna on the back of the module; 3) The test environment will affect the corresponding test results: the general indoor space has reflections, which will cause the sensing distance behind the module to be relatively far. But in an outdoor environment, this situation will be reduced.
Q: How many lamps can be used in the DALI system?
A: A standard DALI system can carry up to 64 components with independent addresses. The maximum current provided by the DALI system is 250mA, which is a limitation of the DALI system. If a DALI system has more than 64 independent addresses or the system current is greater than 250mA, the signal will be attenuated, distorted, and cause system errors. Some components may not be able to communicate and the system will run unstable.

Q: What should I pay attention to when installing or using the radar module?
A: 1) The sensing distance is tested under ideal conditions. The actual sensing distance is related to the hanging height, the openness of the test site, the height and shape of the tester, and the pace of the tester. The sensing distance of the final product is recommended to be subject to the actual measurement; 2) When the radar sensors are densely distributed, try to ensure that the antennas of the radar are parallel to each other to avoid direct illumination between the antenna surfaces. →For scenarios where the radar antennas may illuminate each other, it is recommended that the installation distance exceeds 1m; →For scenes that require dense distribution such as aging test, ensure that there is a distance of more than 20cm between the lamps. 3) Microwave induction radar has a certain wall penetration capability, which can penetrate thin wooden walls and glass walls, but generally does not easily penetrate solid brick walls.
