Description

Light collecting member and lighting device

The present invention relates to a lighting fixture, and more particularly to a light collecting member and a lighting device that can be used as a flashlight or a camping light.

Camping activities have always been a popular activity, and you need to bring the right equipment to enjoy the event. Flashlights and camping lights are indispensable when camping outdoors in the dark. In order to reduce the cumbersome carrying items and the purpose of lightness, products that combine the functions of both have appeared in recent years. For example, a lighting device disclosed in Taiwan Patent No. M323554 can be used as a flashlight or a camping lamp.

In such portable devices, batteries are often used as a source of energy and energy is limited, and how to use energy efficiently is an important issue. However, the foregoing illumination device uses a projection lamp with a plurality of planar light source devices as a light source, and respectively covers different directions to achieve the effect of a flashlight or a camping lamp. The aforementioned illuminating device is more energy-consuming because it has a large number of light sources, and part of the energy is converted into light but is blocked from being able to exert the lighting effect, and only the unshielded portion can effectively use the energy, which is a waste of energy.

Therefore, it is an object of the present invention to provide a light collecting member having a light collecting effect and indirectly saving energy.

Another object of the present invention is to provide a lighting device that can be used as a flashlight or camping light.

Thus, the novel light collecting member comprises a cover unit and a light reflecting unit. The cover unit has a base wall, a surrounding wall extending around the base wall and extending from the base wall in a first axial direction, and at least one light-transmitting hole disposed in the surrounding wall. The base wall and the surrounding wall together define a collection zone. The light collecting region has an opening opposite to the base wall. The light reflecting unit is disposed in the light collecting region and has a tapered shape and can reflect light, and has a base connected to the base wall, a vertex opposite to the base along the first axial direction, and a base toward the base The apex extends as a tapered cone.

The novel lighting device comprises the light collecting member and a light emitting member. The illuminating member includes a grip portion adapted to be gripped, a light emitting portion connected to the grip portion, and a light source disposed on the illuminating portion. The cover unit of the light collecting member can be positioned on the light emitting member by the surrounding wall. When light is emitted from the light source of the illuminating member and illuminates the tapered surface along the first axial direction, the light is reflected by the tapered surface and converges to the apex.

The effect of the novel is that the present invention has a light collecting effect by reflecting and converging light to the apex of the light collecting member. In addition, the illuminating device of the present invention can be used as a flashlight by using the illuminating member, and the combination of the illuminating member and the illuminating member can be used as a camping lamp, and the energy saving effect is indirectly achieved by the illuminating member.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , an embodiment of the illuminating device of the present invention comprises a illuminating member 1 and a concentrating member 2 .

The illuminating member 1 includes a grip portion 11 adapted to be gripped, a light emitting portion 12 connected to the grip portion 11 and a light source 13 disposed on the illuminating portion 12.

The light collecting member 2 includes a cover unit 3, a light reflecting unit 4, and a hook 5.

The cover unit 3 has a base wall 31, a surrounding wall 32 surrounding the base wall 31 and extending from the base wall 31 along a first axial direction L1, and three transparent holes 33 disposed in the surrounding wall 32. The base wall 31 and the surrounding wall 32 together define a collection zone 34. The base wall 31 is removably pivoted to the surrounding wall 32 and rotatable about the first axial direction L1, and has a protruding portion 311 opposite to the collecting portion 34, and is disposed on the protruding portion 311. Suspension hole 312. The hook 5 can be attached to the base wall 31 by the hanging hole 312. The light collecting region 34 has an opening 341 opposite to the base wall 31. The surrounding wall 32 has a recess 322 adjacent to the inner side surface 321 of the light collecting portion 34, and a circular opening 341 which is adjacent to the inner side surface 321 and adjacent to the light collecting portion 34, and is embedded in the embedded surface An O-ring 323 is defined in the groove 322 and protrudes from the inner side surface 321 . The cover unit 3 can be sleeved on the light-emitting portion 12 of the light-emitting member 1 and positioned relative to the light-emitting portion 12 by the frictional force of the O-ring 323.

The light reflecting unit 4 is disposed in the light collecting portion 34 and has a tapered shape and can reflect light, and has a base portion 41 connected to the base wall 31, and a vertex 42 opposite to the base portion 41 along the first axial direction L1. And a tapered surface 43 which is tapered and has a concave arc shape when the base portion 41 extends toward the apex 42.

When light is emitted from the light source of the illuminating member 1 and is incident on the tapered surface 43 along the first axial direction L1, the light is reflected by the tapered surface 43 and converges to the apex 42. The illuminating member 1 which originally only produces the illumination effect along the first axial direction L1 and can be used as a flashlight, can thereby form a new light source by concentrating the light effect on the apex 42 and pass the light through the transparent holes 33 The surrounding scattering further makes the present invention usable as a camping light. At the same time, the light convergence effect does not lose light due to obscuration, and indirectly achieves energy saving effects.

It should be noted that, in this embodiment, the number of the light-transmitting holes 33 is three, but may be one, two or four, and the light-transmitting holes 33 may shield the material of the light-transmitting effect of the device (Fig. Not shown), so that the new model still maintains the lighting effect but the light is less glaring. In addition, in the present embodiment, the light collecting member 2 is used in conjunction with the light emitting member 1, but it may be used in combination with a commercially available flashlight or other light source, and the light collecting member 2 can be independently manufactured and sold.

In summary, the novel light collecting member 2 reflects and concentrates the light to the apex 42 by the tapered surface 43 of the light reflecting unit 4, and has a light collecting effect. In addition, the illuminating member 1 of the illuminating device of the present invention can be used alone as a flashlight, or can be used as a camping lamp in combination with the concentrating member 2, and indirectly achieves energy saving effect by the concentrating member 2, so the new type can be achieved. The purpose.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
