Embodiment Construction

[0013] figure 2 A preferred embodiment of the present invention is shown, and the portable floodlight includes a lamp cap 110, a luminous body 150 placed in the lamp cap, a curved reflector 130, a rotating mechanism 160, a transparent member 120 placed above the lamp cap, a transparent The part 120 is provided with a convex lens 140 and is directly above the illuminant 150, and the outer side of the lamp head is connected to the rotating mechanism with a knob 161, a housing 100 and a power supply 170 placed in the housing 100 to supply power to the illuminant 150.

[0014] The light emitter 150 in this embodiment is a light emitting diode.

[0015] The convex lens 140 disposed on the transparent member 120 is located directly above the illuminant 150 , and when the illuminant 150 is emitting light toward the convex lens 140 , light is collected by the convex lens.

[0016] The curved reflector 130 is arranged at the rear end of the lamp head, and maintains a certain lateral ...

Abstract

The invention relates to a portable spotlighting-floodlighting lamp which comprises a lamp holder (110), a shell (100), a battery (170) for providing a power supply for a luminous body (150) and a transparent part (120) arranged on the lamp holder (110); the portable spotlighting-floodlighting lamp is characterized in that a convex lens (140) is arranged on the transparent part (120); and the lampholder (110) is internally provided with a curve surface reflector (130) and a luminous adjusting mechanism (160) for projecting the light of the luminous body (150) to the convex lens (140) or the curve surface reflector (130). The lamp can realize the spotlighting-floodlighting function only by one light source, the spotlighting and the floodlighting are independent and have no flaw, and when only one light source is used, the spotlighting and the floodlighting formed by the two reflectors are not interfered mutually.

Description

technical field [0001] The invention relates to a lamp, more specifically, to a portable lamp for focusing and flooding. Background technique [0002] Existing LED flashlights do not have the function of focusing and floodlighting, and the lighting function is single. When walking at night, the flashlight needs to have a wide range of illumination nearby. However, the existing flood-focusing reflectors form the flood-light by defocusing or frosting the reflector. The flood-focusing formed by the de-focusing form will inevitably lead to black holes, and black holes will appear in areas that require flashlight lighting. The use function of the flashlight will be lost; and the floodlight formed in the form of reflector frosting will greatly reduce the lighting effect of the lamp. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problem that one light source realizes the function of focusing and flooding and that the focusing and flooding...
