Description

Lamp unit with switchable lighting mode

The invention relates to a luminaire device with a switchable illumination mode, which is applied to the technical field of luminaires, in particular to a luminaire device capable of switching the illumination mode of the light.

The application of lamps is quite extensive, such as medical, automotive, indoor and outdoor lighting, leisure out, engineering, etc., and the lamps adjust the illumination range and replace the light source according to different environmental requirements.

Generally speaking, when engineers are working at night, they usually wear headlights on their heads to free their hands for construction. When they are active or working in dark spaces such as mine pits, caves, sewers, tunnels, etc., they need to respond to the environment. The focal length is adjusted by the distance of the space, and there are zoomable lamps on the market to provide a user with a change in the focal length of the illumination as the environment changes. Please refer to the Republic of China Patent Publication No. M389264 "Zoom device for light source", which comprises: a base, a light-emitting unit, the light-emitting unit is disposed on the base; a telescopic device, the telescopic device is disposed on the light-emitting device Outside the unit, and combined with the base; a light transmissive body, the light transmissive system is disposed at the telescopic device; a power supply device is provided to provide power for the light emitting unit; thereby, forming a light source Zoom device. The light transmissive body can be disposed on the telescopic device, and the telescopic device can be coupled to the base to achieve the zoom effect.

However, the aforementioned zoom device can provide a zoom effect through the telescopic device, but in the environment of fogging, raining, and unclear vision, it is necessary to provide high-intensity light, so that the user can be in an unclear environment. , still can clearly check Looking around the environment, and providing other people in the environment to detect their location, so the effect of arranging fog lights in the luminaire can meet the needs of individual users.

The principle of the general fog lamp is to achieve the effect of the fog lamp by changing the shape of the light, the concentration, the wavelength of the light and the engraving on the lamp cover, thereby providing high-intensity light, and the conventional fog lamp effect is to install a reflection surface in the lamp housing. The concentrating seat and the visor are used to control the shape and brightness. At least two sets of light source groups are installed in the luminaire and arranged in different areas to achieve the effect of the illuminating lamp and the fog lamp. Please refer to the Republic of China patent. Bulletin No. M365862 "Multi-function lamps for vehicles".

However, although the headlight of the prior art has a zoom effect, it cannot provide the illumination effect of the fog lamp, and another lamp of the prior art can switch different illumination modes, but it is set by using various light source groups. Different regions, in this way, must rely on more parts and components, and increase the complexity of assembly, resulting in increased weight, and can not reduce the size of the lamp, and has the disadvantage of being difficult to assemble.

In addition, the white light emitting diode generally used has a blue light and a yellow light band, and the light wave which is scattered in the mist is a blue wave band (ie, a light wave of a shorter wavelength). If a white LED is used directly, the blue spectrum of the output spectrum of the luminaire will cause scattering in the mist.

In view of the above-mentioned lack of various conventional technical lamps, the inventors have devoted a lot of time to research related knowledge, and compared various advantages and disadvantages, and carried out research and development of related products, and after many experiments and tests, finally launched a kind of "Lighting device with switchable lighting mode".

The main object of the present invention is to provide a general lighting effect and a switchable effect to a fog light with a simple structure to easily switch between the two different lighting modes.

Another object of the present invention is to eliminate the blue band produced by the white light emitting diode with a fog mirror and to preserve the long wavelength band that provides better illumination in a fogging environment.

In order to achieve the above object and effect, the present invention provides a luminaire device of a changeable illumination mode, comprising: a main body, an illuminating portion, and a illuminating component; and a lens group disposed on the main body and Corresponding to the illumination part, the lens group includes a fog mirror, an inner spiral ring and an outer rotating ring, the fog mirror is pivoted in the illumination part, and the fog mirror is disposed corresponding to the light emitting component, and the inner rotating ring is sleeved with the illumination part, and The inner rotating ring interlocking fog mirror is turned over with respect to the illumination part, and the outer rotating ring is sleeved with the inner rotating ring and drives the inner rotating ring to rotate; wherein, by adjusting the outer rotating ring, the inner rotating ring is linked to the positive and reverse rotation of the inner rotating ring to The fog mirror is turned over relative to the illumination portion, so that the fog lens covers the light-emitting element or turns off the light-emitting element to achieve the effect of light zooming.

According to a further feature of the present invention, the fog mirror is provided with a shielding portion corresponding to the light-emitting component, the outer portion of the passive portion is provided with a diagonal sliding rail, and the inner rotating ring is provided with a sliding rib for inserting the oblique sliding rail. The two ends of the fog mirror are respectively provided with a pivot rib, and the corresponding pivot ribs on both sides of the base are provided with pivot grooves, and the pivot ribs are pivoted in the pivot groove.

According to the description of the above structure, please refer to the second to fifth figures, which is the operation process of switching the general illumination mode and the fog lamp mode in the present invention, and the mode in the fourth figure is the fog lamp mode, which is transmitted through the fog mirror 21 . Before the light-emitting element 12 is covered, the light is passed through the fog mirror 21 to provide high-intensity light to reach the fog light; and when it is desired to switch back to the general illumination mode, only the outer ring 23 is reversely rotated, as shown in the fifth figure. After the outer ring 23 drives the inner ring 22 to rotate in the reverse direction, the fog mirror 21 is turned upside down relative to the illumination portion 11, and The state in which the fog mirror 21 is covered on the light-emitting element 12 is released, whereby the light of the light-emitting element 12 can be directly irradiated to the environment to provide a general illumination source. Therefore, it can be seen that when the present invention is to adjust the light to the general illumination state and the fog lamp state, only the reciprocating rotation of the outer ring 23 is required, and the effect can be easily achieved.

The invention has the advantages that the simple structure of covering the light-emitting element 12 or the light-emitting element 12 only by the fog mirror 21 and the rotation of the outer ring 23 can adjust the effects of the general illumination mode and the fog illumination mode, and are composed of simple components. The simple switching means achieves the effect that the invention is suitable for the small body 1 and the fast switching illumination mode.

In addition, the mist mirror 21 of the present invention is a wavelength filter, a color patch which can cause a filtering effect, etc., to eliminate the blue wavelength band of the white light emitting diode, and retains a yellow color which can provide a better lighting effect when fogging. To the red band, reducing or weakening the stray light generated by the scattered light during fogging makes the object seen in the fog clearer.
