Energy-saving LED fluorescent lamp device

Abstract

The invention discloses an energy-saving LED fluorescent lamp device with better energy-saving effect, which comprises an LED lamp, a PCB, a lamp tube, a fluorescent lamp cap, a fluorescent lamp holder electrode and a circuit system, wherein the circuit system of the LED fluorescent lamp device comprises a voltage reduction circuit, a drive circuit, a CPU control circuit and a light detector, ambient light information is collected by the light detector and sent to a CPU, the intensity of the ambient light information is judged by the CPU, and then a corresponding control signal is output to the drive circuit to regulate the size of a constant current value, i.e. regulating the light brightness of the LED lamp, thereby the purposes of automatically regulating the light brightness of the LED lamp, saving energy and lowering consumption are achieved. Through the scheme, the light brightness of the LED lamp can be automatically regulated according to environments under the control of the CPU control circuit, and the energy saving ratio can be increased from 60 percent to 80 percent.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED fluorescent lamp device with high-efficiency and energy-saving effects. Background technique [0002] Lighting power consumption has always been an important part of power consumption. According to statistics from authoritative departments, China's power generation in 2006 reached 2,834.4 billion kwh. %, which is almost 3.5 of the power generation capacity of my country's largest Three Gorges large-scale hydroelectric power station. Therefore, the sharp increase in electricity consumption for lighting and the intensification of energy consumption for power generation will make my country's power supply situation and the current situation of environmental and ecological protection increasingly severe. If the construction of hydropower facilities is unlimited, it will be on the verge of an ecological disaster that destroys the natural environment; if thermal power stations are continuously added, t...

Problems solved by technology

However, since fluorescent lamps have dominated the lighting industry for decades, they have formed extremely rich and skilled experience in lighting application and design, and are widely used in existing fluorescent lamp architectural lighting occasions. The design of the lighting scheme of the lamp is relatively mature. If the LED lamp of other specifications is redesigned and installed, it will inevitably increase the user's use cost.
