Project name: the new 2.4 G LED lamp dimming solution (the new module) + the new remote control because it could not above, to learn more about or ask for information and samples can be QQ594509107
Solution brand: hmwin
Solution functions and features:
This system is a high performance LED 2.4 G + + touch switch panel wireless remote control dimmer color temperature products, mainly due to use of various kinds of need to move light color temperature of LED lights (unlimited power), such as LED bulb light, LED to absorb dome light, LED tube light, LED light plate, such as remote control to control LED lights can be directly, also support wall touch switch panel to control LED lights, one control, can also be a remote control multiple lamps and lanterns, flexible control, convenient use,
1. Remote control parameter
Remote control distance: 50 m
Transmission frequency: 2400-2483.5 MHz
Standby power consumption: 3 ua
Working current: 12 ma
Modulation mode; GFSK
Transmission power: 10 db
Battery: button type
2. The basic function operation:
(1). The code: the remote control in use for the first time, with the LED lamps and lanterns of code after OK, just can be normal use, the light switch the LED lamps and lanterns on 5 seconds press 3 times to the code, the light will flash 3 times at the same time, for success, for after the success of the code, can click to open the key to turn on the light or turn off the light of lamps and lanterns; In the case of not to turn off the lights and other operations that can be normal use the remote control,
(2). The qing code: in some special cases, the need to lift the lamps and lanterns is connected to the control of the remote control, will use the qing code,
The qing code method is: in the continuous light switch the LED lamps and lanterns on 5 seconds press 5 times to the code, the light will flash 6 times, said the qing code is successful, the remote control can't control the light,
(3). Multiple control: use a remote control can control multiple LED lamps and lanterns, simultaneously, the premise is to use the same first, respectively, and various lamps and lanterns of remote control code, such as: when press the mode button on the remote control, all the lamps and lanterns will change at the same time, synchronized, as long as within the range of 50 m, a remote control theory and control many (& gt; 100) of the LED lamps and lanterns, if customers have some reinforced concrete walls, may reduce the effective control of the remote control distance,
(4). A remote control can control multiple lamps
Toning soft brightness, memory function, mode of lamps and lanterns, episodic memory specific see manual operation,
2. The receiving module
Working current: 20 to 25 ma
The PWM frequency: 4000 hz
Working temperature: - 20-85 - c
Dimension: 24 mm * 14 mm * 4 mm
Function description: the receiving module in addition to implement the directives issued by the remote control, includes light changing functions, namely: white, warm white, neutral light, small night light four optical switching,
Power design considerations (special attention should be paid to)
Power supply requirements
This system requires constant current or constant voltage power supply, and has fast response speed, PWM control module is almost 4 m (1000 * 4000) frequency, for the current source and testing of constant current source is not possible, (reason is the reaction speed too slow, will cause the LED lights flashing, jitter, such problems as poor modulation, there may be some power supply manufacturer can do, the customer need to test type), had better use the power of secondary triode testing feedback, reaction speed, (and the threshold voltage to the direct use of light coupling constant current, the effect is very good, is only slightly lower efficiency, and used the transistor constant current detection principle of the same, just the triode low threshold voltage, the efficiency is higher), the general power supply, the cathode is only one, the LED on the control panel can - and V - together, but in the low light is a some effect will be bad, can be divided into two, the power of the cathode LED - are a constant current detection, V - is the final, so that control module with electricity is not through the constant current detection, the low brightness will effect is good,
