TWM325439U - Circuit structure of an intensity adjustable LED light - Google Patents

Description

M325439 is used for heat dissipation. The main body (10) is connected to the power supply terminal (20) with LED electronic voltage regulator (40) and brightness controller (5 〇). Referring to the first and fourth figures, the brightness controller (50) includes an AC power supply voltage detecting unit (51), an LED output control (52), and a lamp body temperature detecting unit (5 3); Referring to the third figure, the AC power supply (60) passes through the dimmer (7 〇), and the '70' is used as the Triac 〇r SCR commonly used in the market to transmit the voltage (flow) to the LED electronic stability. Pressure (8) (4 〇) and brightness controller (5 〇), electronically regulated (flow) (40) provides the stable power required to illuminate the LED group (3 〇), brightness controller (5 〇) The AC power supply voltage fine unit (5 workers) detects the AC power status record of entering the LED light, and the recorded value is compared with the value of the s value of her method or service (according to the technique of 'this method is known as f, Not the focus of this case), through (10) output control (5 2) to adjust the voltage (flow) output to (10) with PWM or power transistor, you can control the rib lamp group with LED output control (5 2 ) 3 billion). • brightness. For example, when the power supply voltage is in Qingqing Temple, the output _ to (10) light (four) 〇), when the power supply voltage is between the bribes, the miscellaneous output is changed by the power supply voltage, and the control (four) light group (3 〇) brightness The purpose. In addition, the temperature body of the lamp body (53) is the simple sensitive wire side lamp body (the temperature of 3 υ is controlled by the LED wheel control (5 2) to determine whether to reduce the output, basically 45 degrees C as the critical point' 45 Below the degree c, turn out _, when the temperature is two, the output voltage of the pair is reduced, and when it reaches 6 (8), it is reduced to _ output to achieve the purpose of overheat protection LED. 7 M325439 When using this creation, the LED light will be The dimming function, combined with its own characteristics of natural and natural light, will be more practical. Therefore, the above-mentioned products have been developed, and the utilization value of the industry has been improved. At present, there is no such product, so the case is in line with novelty.
