Abstract

The invention relates to a portable lamp which comprises a shell, a lamp holder arranged on the shell, as well as a spotlighting reflector, a floodlighting reflector, a light source and a rotating shaft which are arranged in the lamp holder, where the rotating shaft is used for mounting the light source and driving the light source to rotate, two ends of the spotlighting reflector are open, the spotlighting reflector is positioned on the lateral wall of an inner cavity of the lamp holder; the floodlighting reflector is positioned at the bottom of the inner cavity of the lamp holder; two ends of the rotating shaft are positioned on the lateral wall of the inner cavity of the lamp holder, and at least one end of the rotating shaft penetrates the lateral wall of the inner cavity of the lamp holder; and the light source is positioned below the lower-end opening of the spotlighting reflector. The portable lamp achieves the switching between the spotlighting function and the floodlighting function by rotating the light source to match the spotlighting reflector and the floodlight reflector, considers both spotlighting and floodlighting, is convenient for using and has good illumination effect.

Description

Portable lamp

Technical field

The present invention relates to the portable lamp field, more particularly, relate to a kind of portable lamp that can realize optically focused and two kinds of illumination functions of floodlight.

Background technology

The portable lamp of prior art, particularly adopt the portable lamp of led light source, illumination functions is single, can't take into account spotlighting and floodlighting simultaneously, this can bring a lot of inconvenience in can giving and using, and for example, night is when walking, need the illumination of illumination broadness nearby, also need to shine spotlighting at a distance.Existing portable lamp with floodlight and light-focusing function generally adopts the mode of out of focus or the effect that reflector frosted mode realizes floodlight and optically focused.The light fixture of out of focus formula tends to uneven illumination, and blackening and black hole can appear in hot spot, and the mode of reflector frosted then can reduce the illuminating effect of light fixture greatly.

Summary of the invention

The technical problem to be solved in the present invention is, at the above-mentioned portable lamp uneven illumination of prior art, the defective of illuminating effect difference, provides a kind of illuminator rotatable portable lamp, can realize two kinds of exchange functions of floodlight and optically focused.

The technical solution adopted for the present invention to solve the technical problems is: construct a kind of portable lamp, comprise housing, be arranged on the lamp holder on the housing, it is characterized in that, also comprise the optically focused reflector that is arranged in the lamp holder, the floodlight reflector, light source, and be used to that light source is installed and drive the rotating shaft that light source rotates, described optically focused reflector both ends open, described optically focused reflector places on the sidewall of lamp holder inner chamber, described floodlight reflector places the bottom of lamp holder inner chamber, described rotating shaft two ends place on the lamp holder intracavity sidewall and at least one end passes sidewall, and described light source is positioned at the below of the lower ending opening of optically focused reflector.

In portable lamp of the present invention, described optically focused reflector is the funnel-form reflector, and described floodlight reflector is a reflective surface, with the angled setting in lamp holder inner chamber bottom surface.

In portable lamp of the present invention, described rotating shaft passes sidewall one end and is provided with the knob that is used to rotate this rotating shaft.

In portable lamp of the present invention, described knob is provided with the positioning convex that is used for anti-rotating shaft degree of rotating through, and described lamp holder outer wall is provided with the position block adaptive with it.

In portable lamp of the present invention, described light source is the LED illuminator.

Implement portable lamp of the present invention, has following beneficial effect: change thereby portable lamp of the present invention cooperates with optically focused reflector and floodlight photophore to be implemented between spotlighting and the floodlighting function by the rotation light source, take into account spotlighting and floodlighting, easy to use, and good illumination effect.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the schematic perspective view of portable lamp preferred embodiment of the present invention;

Fig. 2 is the cutaway view of portable lamp preferred embodiment of the present invention when being in spotlighting;

Fig. 3 is the cutaway view of portable lamp preferred embodiment of the present invention when being in floodlighting.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, in portable lamp preferred embodiment of the present invention, comprise housing 100, be arranged on the lamp holder 110 on the housing, be arranged on the power supply 170 in the housing, also comprise the optically focused reflector 140 that is arranged in the lamp holder 110, floodlight reflector 130, light source 150, and be used to that light source 150 is installed and drive the rotating shaft 160 that light source 150 rotates, optically focused reflector 140 both ends opens, be installed on the sidewall of lamp holder 110 inner chambers, rotating shaft 160 two ends are installed on the sidewall of lamp holder 110 inner chambers and an end passes sidewall, light source 150 is installed in the rotating shaft 160 and can rotates with rotating shaft 160, light source 150 is positioned at the below of optically focused reflector 140 lower ending openings, and described floodlight reflector 130 places the bottom of lamp holder 110 inner chambers.

In the preferred embodiment of the present invention, optically focused reflector 140 is the funnel-form reflector, and floodlight reflector 130 is a reflective surface, in order to guarantee illuminating effect, floodlight reflector 130 and the lamp holder angled setting in 110 inner chamber bottom surfaces.

In the preferred embodiment of the present invention, rotating shaft 160 passes lamp holder sidewall one end and is provided with knob 161, be used to make things convenient for rotating shaft 160, for rotating shaft 160 anglecs of rotation are controlled within the specific limits, prevent that the anglec of rotation is excessive, light source 150 is in non-best relative position with reflector, and knob 161 is provided with the protruding (not shown) that is used to locate, and the lamp holder outer wall is provided with the position block (not shown) adaptive with it.

In the preferred embodiment of the present invention, light source 150 is the LED illuminator, has the luminous efficiency height, advantage of low energy consumption.

During use, when needing spotlighting, rotation knob 161 drives rotating shaft 160 rotations, make light source 150 rotate to the position of light-emitting area over against optically focused reflector 140 lower ending openings, referring to Fig. 2, the light that light source 150 sends throws away after the reflection of optically focused reflector, forms the light beam that converges together, spotlight effect is good, and illumination is even, and hot spot blackening or black hole can not occur, suitable directed remote illumination; When needing floodlighting, light source 150 is rotated to the position of light-emitting area over against floodlight reflector 130, referring to Fig. 3, the light that light source 150 sends reflects away through the floodlight reflector, forms evenly illumination on a large scale, suitable closely illumination on a large scale.

In conjunction with the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
