Abstract
The utility model relates to a split LED lamp tube with a power device convenient to maintain and replace. An existing LED lamp tube is in a design integrating LED tubes, a lamp support and a circuit board, after the circuit devices fail, the whole LED lamp tube needs to be replaced by people, and resources are wasted. The split LED lamp tube comprises an LED lamp support, LEDs, an external power plug and an LED power device, wherein the LED lamp support, the LEDs and the external power plug are the same as those in a traditional LED lamp tube, the LED power device is clamped in a groove arranged at the back of the LED lamp support and comprises a casing and a circuit board disposed therein, and power between the LED power device and the LED lamp support is connected via a wire or a contact spring plate. When the LED power device fails, maintenance can be achieved only by detaching and replacing the LED power device. The power device of the split LED lamp tube is convenient in maintenance and replacement, service life is prolonged, cost is reduced, application range is wide, and the split LED lamp tube is suitable for popularization.
Description
Technical field
The utility model relates to the electron-optical field, but is specifically related to the split type LED illuminating lamp tube that a kind of convenient for maintaining is changed supply unit.
Background technology
The traditional fluorescent lamp pipe is substituted by novel energy-saving environment-friendly type LED light fixture gradually because power consumption is big, service life is short.Existing LED illuminating lamp tube is LED lamp pearl, lamp bracket and the design of circuit board integral type, the circuit board that is used as the voltage stabilizing rectification is fixed in the fluorescent tube, the fluorescent tube internal heat dissipating is poor, circuit board element is fragile, maintain and replace needs professional and technical equipment, the condition harshness, after the circuit board element fault, people can only change the integral LED illuminating lamp tube again, cause the waste of resource, influenced the popularization and the utilization of LED illuminating lamp tube.
The utility model content
The purpose of this utility model is to overcome the deficiency of existing integral LED illumination road spot, but provides a kind of convenient for maintaining to change the split type LED illuminating lamp tube of supply unit, increases the service life, and reduces cost.
The utility model is made of LED lamp bracket, LED lamp pearl, external power supply plug and LED supply unit.LED lamp bracket, LED lamp pearl, external power supply plug are identical with traditional LED illuminating lamp tube, are provided with groove at the LED lamp bracket back side, and the LED supply unit in clamping; The LED supply unit is made of the inner circuit board that is provided with of housing and its, and power supply is connected by lead or contact spring between LED supply unit and the LED lamp bracket.
After the integral LED illuminating lamp tube installs, electric current is input on the circuit board of LED supply unit by the plug portion of the external power supply at LED lamp bracket two ends, after the voltage stabilizing rectification, supply with the illumination of LED lamp pearl.
After the LED supply unit breaks down, only need to remove replacing LED supply unit and can reach the maintenance purpose.
But advantage of the present utility model is convenient for maintaining and changes supply unit, prolongs LED illuminating lamp service life, reduces cost, and uses in extensive rangely, is beneficial to popularization.
