Description

Lighting equipment

The present invention relates to a lighting device.

Many campers and hikers often use headlamps while engaged in activities.

By the way, many headlamps provide only a straight line of light, but in activities such as camping, lantern type light (diffuse light) is often required.

Therefore, to reduce the need for separate concentrated light sources and diffused light, or lantern-type light sources, headlamp manufacturers cover the headlamps and take the concentrated light from the headlamps and apply it to the inner surface. A separate appendage was developed to reflect light and then diffuse light through certain materials.

Examples of this method are TR1 + Ambient light Set by Mammut and http://joby.com at http://www.mammut.ch/en/productDetail/232000220_v_0001/TR1+%2B+_Ambient+light+Set.html Indicated by JOBY's gorilla torch switchback located at / gorillatorch / swichback. However, this approach required additional, separate and often bulky equipment accessories, and light inefficiencies could occur due to light concentration, subsequent scattering and diffusion.

Another method is to add an additional light source used only in the lantern mode, as shown in Tarter US Pat. No. 7,635,195. However, this approach uses a separate light source in the headlamp configuration, but requires a dedicated light source for use in the lantern configuration, so that the lantern configuration consumes more energy than the headlamp configuration. In addition, the added light source adds to the size, weight, and complexity of the device.

Users are demanding the appearance of a lightweight, power-saving and efficient lighting device that can generate diffused light and concentrated light with a single unit without requiring separate accessories.

The present invention provides an illumination device that meets the above-mentioned needs.

The gist of the present invention will be described with reference to the accompanying drawings.

Embodiments of the present invention that are considered suitable will be briefly described with reference to the drawings, illustrating the operation of the present invention.

In the non-deformation configuration 12a in which the

cover portions

12, 112, and 212 are located away from the

light sources

32, 132, 232, and 532, the light emitted from the

light sources

32, 132, 232, and 532 is light transmissive or light diffusive. The light is diffused through the cover portion and is emitted to the outside of the

cover portions

12, 112, and 212.

When the

cover portions

12, 112, and 212 are pressed inward toward the

light sources

32, 132, 232, and 532 from the non-deformable configuration 12a, the

cover portions

12, 112, and 212 having elasticity or flexibility are deformed and moved. Then, the

light source

32, 132, 232, 532 is switched to the deformed configuration 12b that is located in the proximity of the

light source

32, 132, 232, 532. The light is irradiated to the outside of the

cover portions

12, 112, and 212 from the light irradiating portion, the

lens assembly

30, 130, 230, or the opening provided in the vicinity of the

light sources

32, 132, 232, and 532.

That is, in this modified configuration 12b, the

light source

32, 132, 232, 532 and the light irradiation unit or

lens assembly

30, 130, 230, or the opening are close to each other. It becomes easy to irradiate to the outside of the

cover portions

12, 112, 212 from 130, 230 or the opening as a concentrated light beam such as spot light.

Further, when the

lens assembly

30, 130, 230 is provided in the

cover portion

12, 112, 212, if a condensing lens is used as the

lens assembly

30, 130, 230, it is easily and surely concentrated on the deformed configuration 12b. Light rays can be generated.

Therefore, according to the present invention, a light, power-saving, and efficient lighting device that can be generated by switching between diffused light and concentrated light, for example, without using an accessory or the like, and a diffused light generation state ( The switching operation from the non-deformed configuration 12a) of the

cover portions

12, 112, 212 to, for example, the concentrated light generation state (the deformed configuration 12b of the

cover portions

12, 112, 212) also simply changes the

cover portions

12, 112, 212 to the light source 32. Since it only needs to be pressed inward toward 132, 232, 532 and deformed, it can be operated very easily.

Specific embodiments of the present invention will be described with reference to the drawings.

Exemplary embodiments of the present invention are shown in FIGS. 1-30, where the same or generally similar features use common reference numerals.

FIG. 1 shows a perspective view of the lantern configuration for generating diffused light of the lighting device 20 of the present embodiment.

The illuminating device 20 of the present embodiment is a luminaire 10 including a base portion 14, a light source 32, a lens assembly 30, and a cover portion 12, and the lens assembly 30 is positioned away from the light source 32. The cover portion 12 is configured to support the lens assembly 30 during translation of the lens assembly 30.

The cover portion 12 has a dome shape and protrudes from one side of a thick disc-shaped base portion 14. The cover portion 12 may be configured in various shapes as will be described later.

Also, a power switch 60 is provided on the outer peripheral surface of the base portion 14, and by operating the power switch 60, it is configured to be able to perform lighting / extinguishing control, constant lighting / strobe switching, and illuminance switching.

FIG. 2 shows the cover portion 12 of FIG. 1 deformed inward in the middle of the dome shape.

FIG. 3 shows a partial cutaway view of an embodiment of the luminaire 10. Cover portion 12 is shown twice as 12a and 12b, where 12a is a dome-shaped cover portion 12 that is an undeformed configuration, and 12b is the center of dome-shaped cover portion 12 being pushed toward light source 32. This is a cover portion 12 having a modified configuration.

Also, the undeformed configuration 12a may be described as the luminaire 10 in a “lantern” configuration, and the deformed configuration 12b may be described as the luminaire 10 in a “concentrated light” configuration.

FIG. 3 also shows a lens assembly 30 fitted to the cover portion 12 and a light source 32 installed near the inner surface 34. The cover portion 12 is perforated at a position where the lens assembly 30 may block so that the lens assembly 30 is moved closer to the light source 32 when the cover portion 12 is deformed into a concentrated light configuration (deformed configuration 12b). You may prepare.

The lens assembly 30 may be configured to direct most of the light emitted from the light source 32 through the lens assembly 30 to produce the desired lighting effect. The illumination effect may be concentrated light or light that is less diffuse than when the lens assembly 30 is not in proximity to the light source 32.

The lens assembly 30 may be guided and fixed by a positioning mechanism 38 on or near the lens assembly 30 and a positioning mechanism 36 near the light source 32.

The

positioning mechanisms

36 and 38 may be configured so that only one exists, or may function in cooperation or independently. In addition, the positioning mechanism 36/38 may take the form of a magnet in the positioning mechanism 36 and another magnet in the positioning mechanism 38 that is attracted to the magnet, or one of the magnet and the attractive metal at each position. It may take the form of a combination of a magnet and an attractive metal, or it may take the form of a recess and a protrusion configured to fit into the recess, the recess being a groove, It may take the form of a protrusion modified to fit and detachably engage with the side of the groove as an interference fit. It may also include, but is not limited to, electromagnet and metal combinations, surface fasteners, tacky or reusable adhesives.

Further, the positioning mechanism 36/38 may hold the lens assembly 30 in proximity to the light source 32 in both the longitudinal direction and the radial direction, in other words, the positioning mechanism 36/38 holds the lens assembly 30 in three dimensions. It may be held close to the light source 32.

The cover portion 12 may be made of a deformable material. The deformable material may be elastic or flexible. The material may be light transmissive and / or diffusive. Suitable materials include, but are not limited to, elastomers or stretchable materials such as rubber, rubber compounds, thermoreversible elastomers, thermoreversible polyurethanes, thermoreversible rubbers, or silicones. The material used may be modified to not only diffuse light to the desired level while in the undeformed position (cover portion 12 is in the undeformed configuration 12a), but also provide the desired elasticity and durability. Good. The material selected can determine the configuration and thickness used. It is known to those skilled in the art that the wall thickness may range from less than 1 millimeter to more than 5 millimeters to achieve the desired combination of transparency, diffusivity, elasticity, durability, manufacturability, and cost. Yes.

The cover portion 12 also has a lens on the inside toward the light source 32 to allow the

positioning mechanism

36, 38 to position and removably hold the lens assembly 30 near or in proximity to the light source 32. It may be configured to move closer to the light source 32 by pushing the assembly 30 or pushing near the lens assembly 30. The lens assembly 30 may be moved from the light source 32 by pushing inward over the cover portion 12 at a point away from the lens assembly 30 to overcome the holding force of the

positioning mechanisms

36,38.

Further, the cover portion 12 has a concave curved shape (concave hemispherical shape) in which the lens assembly 30 is closest to the light source 32 by pressing the lens assembly 30 or the vicinity of the lens assembly 30 inward toward the light source 32. The deformation structure 12b is configured to be deformed.

The light source 32 may be an electrical light source including, but not limited to, a light emitting diode (LED), two or more LEDs, and an incandescent light source or a fluorescent light source.

The lens assembly 30 may be configured to direct light emitted from the light source 32 so as to focus or defocus. Those skilled in the art will recognize the various configurations and materials used to create lenses that produce the desired light from a single light source or multiple light sources.

The lighting fixture 10 may be almost sealed or sealable. Sealing may prevent unwanted debris and water ingress that could damage the instrument. The seal may confine air in the area 16 under the cover portion 12 such that movement or deformation of the cover portion 12 increases or decreases the pressure in the instrument. The instrument may be sealed to create a higher pressure when the cover portion 12 is deformed (when in the deformed configuration 12b) so that the lens assembly 30 is proximate to the light source 32. This increased pressure may require the

positioning mechanisms

36, 38 to be properly configured to overcome the separation force associated with the pressure resisting deformation. This positive pressure also helps the user return the cover portion 12 to the non-deformed position (non-deformed configuration 12a).

The inner surface 34 may be treated to be a reflective surface. Base portion 14 may house a power source 40. The power source may consist of, but is not limited to, a battery, solar system, wind system, crank system, fuel cell, power source including a combustion power source.

FIG. 4 shows a partial cutaway view of an embodiment of the luminaire 10. In the present embodiment, the cover portion 12 is shown in an undeformed shape (non-deformed configuration 12a).

FIG. 5 shows a partial cut-out diagram in the concentrated light configuration in which the inclination is adjusted to a value larger than zero according to the present embodiment.

Specifically, the base portion 14 is provided with a tilt mechanism so that the light source 32 can be tilted. This tilt mechanism is configured such that a hinge is provided on the base portion 14 and the light source 32 tilts together with the base portion 14 via the hinge.

Further, the hinge is provided with a locking claw and a plurality of engaging portions that can be engaged with the locking claw, and by selectively engaging the locking claw with the plurality of engaging portions, The inclination angle (light irradiation angle) can be selectively changed.

In this embodiment, the luminaire 10 may be adjusted so that light emitted from the light source 32 through the lens assembly 30 is directed away from the central axis of the mounting surface 52.

FIG. 6 is a perspective view of the concentrated light configuration in which the inclination is adjusted to a value larger than zero according to the present embodiment.

In this embodiment, the lighting device 20 may be configured to be fixed around the user's head by using the strap assembly 18 with the adapter 22. The adapter 22 may be configured to hold the strap assembly 18 so that it can be adjusted at different lengths. Adapter 22 may also be configured to removably attach to various surfaces and structures. One such configuration may be in the form of a hook as seen in FIG.

7 to 21 show diagrams of various other embodiments. 14 to 21, the lens assembly 30 is not attached to the cover portion 12, and an opening (through hole) is provided at the center of the cover portion 12. This opening is modified so that the light source 32 can pass through the opening and protrude to the outside of the cover portion 12 while the cover portion 12 is being deformed (while being in the deformed configuration 12b). Alternatively, the lens assembly 30 may be modified to allow the lens assembly 30 to pass through the opening while the lens assembly 30 is secured adjacent to the light source 32 and the cover portion 12 is deformed. Lens assembly 30 or other mechanism may be used to releasably hold cover portion 12 in a deformed state.
