Description

Technical Field

[0001] The present disclosure relates to the field of lighting technology, and in particular to a magnetic track lamp dial circuit and a magnetic track lamp grouping system. Background Art

[0002] As the masterless lamp design enters thousands of households, consumers have a deeper understanding of the use of lighting, which in turn affects the demand for dimming or dimming color temperature control. Back to lighting design, masterless lamps basically include point and line luminous bodies such as downlights and light strips. In the highly flexible and diversified market, magnetic track lamps are derived. Their representative working voltages are DC24V or DC48V DC safe low voltage. Combined with control requirements, there are dimming methods such as 0 / 1-10V / DALI. Of course, the track structure has also changed, with 4-wire and 6-wire systems, in order to use more copper bars as signal lines.

[0003] Similar technologies on the market can basically be divided into three types: 0 / 1-10V, DALI and wireless, as follows:

[0004] 1) 0 / 1-10V: The traditional wired dimming method of lighting uses a DC low-voltage method to control the output current of the LED control device to achieve dimming. When used on magnetic lamps, because the dimming signal is a level, the lamps that receive the dimming signal on the same track will uniformly perform dimming changes, and it is impossible to achieve single-lamp single control. And one set of signals cannot achieve both dimming and color temperature adjustment. The usual practice is to add another set and use 2 sets of 0 / 1-10V signals to achieve dimming and color adjustment. This means that in addition to the basic 2 power supply lines, the magnetic track needs to add 4 more lines to handle the transmission of 0 / 1-10V dimming and color temperature adjustment signals. The 6-wire track means there are 6 copper bars. Non-standard products will greatly increase the cost and wiring difficulty of the product.

[0005] 2) DALI: A wired dimming method for lighting with a digital addressing protocol. Each master controller has 64 addresses and is independently controllable. The latest DALI2 protocol supports dimming and color temperature adjustment. The disadvantage is that the cost is too high. From the solution and implementation cost of the entire system to the unit cost of the DALI dedicated chip embedded in the lamp, the customer's budget will be greatly increased;

[0006] 3) Wireless: Whether it is Bluetooth, Zigbee or WiFi, they basically communicate in the 2.4GHz frequency band. Processing wireless signals in magnetic lamps is a big problem. The natural U-shaped groove of the track shields 3 / 4 of the antenna signal direction. The remaining lower surface is often packaged with a metal substrate because of the existence of the light source. The fully enclosed metal closed structure is very unfavorable for RF signal communication; in addition, each magnetic lamp needs to be embedded with a wireless module, which will increase the number of nodes in the system, and the RF signal channel in the space is prone to blockage, increasing the risk of packet loss for some devices.
