Abstract
The utility model relates to a portable lighting device, in particular to an LED flashlight. The utility model is designed for eliminating the defects with the existing flashlights with respect to monadic lighting level, short service life of the bulb, high power consumption and monadic function. This LED flashlight comprises a lamp assembly, a housing of the barrel and an internal circuit. In the lamp assembly, an LED fastening board is arranged where the LEDs are fixed. The LEDs comprises 2 sets. In one set, the LEDs are connected with one another in parallel and with switch S NH1 in series to form a branch while in the other set, the LEDs are connected with one another in parallel and with switch S NH4 in series to form another branch. Both branches are connected in parallel at the two terminals of the power supply. In the two branches, diode D is connected across the anodes of the LEDs. With LED as luminaire, this utility model has the advantages of long service life, energy efficiency, rational design for internal circuit and adjustable lighting level. Moreover, this flashlight arouses interest and provides entertainment, and is highly popular among pupils and students of primary and secondary schools.

1Series connection forms branch road, another group light emitting diode parallel with one another again with switch S
4Series connection forms branch road, and two branch roads are parallel to both ends of power, are connected with diode D between the anode of the light emitting diode in two branch roads.Work as switch S
1When closed, because the unilateral conduction of diode D has only one group of light emitting diode bright; Work as switch S
4When closed, two groups of light emitting diodes are simultaneously bright, thereby realize the brightness regulation of flashlight.
On the light emitting diode fixed head, also be fixed with laser tube JGG, laser tube JGG and switch S
2Series connection also is parallel to both ends of power with this series arm.Switch S
2Closure, laser tube JGG is luminous.The setting of laser tube JGG can increase the function and the interest, recreational of this flashlight.
Also be parallel with a color lamp controller IC at both ends of power
1, color lamp controller IC
1Input be connected with switch S
3, output is connected with three colorful light-emitting diodes that are fixed on the cylindrical shell.Switch S
3Closure once, three colorful light-emitting diodes begin flicker, switch S
3A closed again colorful light-emitting diode stops flicker.So, can further increase the interest, recreational of this flashlight.
Light emitting diode flashlight described in the utility model adopts light emitting diode as light source, long service life, and economize on electricity, internal circuit design is reasonable, makes the illumination adjustable brightness.Simultaneously, owing to the setting of the colorful light-emitting diode on laser tube and the cylindrical shell, increased the function of this flashlight, it is interesting, recreational that this flashlight has been had, and is subjected to liking of students in middle and primary schools deeply.
