Abstract
The utility model belongs to the technical field of the LED projecting lamp, relate to a LED lamp pearl protection architecture, including zener diode, zener diode sets up on the PCB board, and this zener diode sets up with the LED chip in the LED lamp pearl is parallelly connected, the heat sink of LED chip sets up on the boss of the red metal material layer of PCB board, and the positive and negative pin of this LED chip welds on the circuit copper foil layer boss of PCB board, the external LED constant current drive power supply of LED chip, LED lamp pearl is high -power LED lamp pearl. The utility model has the advantages of the safety and stability, lowering the temperature, increase of service life.
Description
Technical field
The utility model relates to LED projector lamp technical field, particularly relates to a kind of LED lamp bead operator guards.
Background technology
Projecting Lamp is the light fixture of the projecting environment of illumination of specifying on face to be illuminated; also known as spotlight; most employing great power LED is as its light source; and the lamp pearl unprotect device of LED projector lamp of the prior art; particularly when voltage or electric current shakiness; or temperature too high time, cause the permanent damages of LED lamp bead.
Summary of the invention
The problem that the utility model pin will solve is to provide a kind of safety and stability, reduces temperature, the LED lamp bead operator guards increased the service life.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of LED lamp bead operator guards; comprise Zener diode; described Zener diode is arranged on pcb board; LED chip in this Zener diode and LED lamp bead is arranged in parallel; the heat sink of described LED chip is arranged on the red metal material layers boss of pcb board, and the positive and negative pin of this LED chip is welded on the circuit copper foil layer boss of pcb board.
The external LED constant current driving power of described LED chip.
Described LED lamp bead is large-power LED light bead.
Owing to adopting technique scheme, (1) Zener diode can play electrostatic leakage effect, can also provide stable voltage and current, prevent LED to be burned because electric current is excessive for LED lamp bead, guarantee the service life of LED, and realize the brightness uniformity, stable of LED display; (2) LED constant current driving power is adopted can to guarantee the efficient, stable of circuit; (3) positive and negative pin is welded on circuit copper platinum layer boss, and the heat sink of LED chip is connected on red metal material layers boss, and the thermoelectricity of LED lamp bead can be made to be separated, and thermal conductivity factor increases, good heat conduction effect, extends the service life of Projecting Lamp.
The beneficial effects of the utility model are: have safety and stability, reduce temperature, the advantage increased the service life.
