Downlight device with light energy circulation

The present invention relates to a downlighting device, and more particularly to a downlighting device with a light energy cycle.

A general downlighting device is disposed on a ceiling. The downlighting device comprises a lamp holder and a light bar group disposed on the lamp holder. When the power is on, the light bar group emits light downwardly to illuminate the area of the item, so that The items are clearly visible.

In today's society where energy conservation and carbon reduction are advocated, in order to save power consumption, the light bar group usually adopts a power-saving lamp tube or a light-emitting diode, etc., which can reduce the power consumption of the product, however, it is dissipated in the lamp holder. In the middle or in the unused space, the light energy can no longer be used and wasted. For this problem, the average user will install the solar device in the unused space, and then take the stored energy for other use. .

However, in such a manner of recycling, it is necessary to install a solar device in another unused space, which is cumbersome to use, and thus it is easy to reduce the user's willingness to use.

Accordingly, it is an object of the present invention to provide a downlighting device with light energy that overcomes at least one of the disadvantages of the prior art.

Therefore, the novel recessed light device with light energy circulation comprises a lamp holder, a light bar group, and a photoelectric conversion unit.

The lamp holder is hollow and includes a surrounding wall having a mounting surface, an upper end portion above the surrounding wall, and a lower end portion below the surrounding wall, the surrounding wall defining an accommodating space.

The light bar group is located in the accommodating space and between the upper end portion and the lower end portion, and is disposed around the mounting surface.

The photoelectric conversion unit is disposed above the surrounding wall and closes the upper end portion.

The utility model has the advantages that the light bar group and the photoelectric conversion unit are integrated into one body, and the whole is relatively simple and convenient, and the photoelectric conversion unit can absorb the light emitted by the light bar group, and can generate a photovoltaic effect. The light energy is converted into electric energy and recirculated to the light bar group, which can effectively recover the dissipated light energy, and can achieve the functions of recycling, energy saving and power saving.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , a first embodiment of the present invention has a lamp holder 1 , a light bar group 2 , a photoelectric conversion unit 3 , and a reflector 4 . A back cover 5, a diffusion plate 6, and a light guide plate 7.

The lamp holder 1 is hollow and includes a surrounding wall 11 having a mounting surface 111, an upper end portion 12 above the surrounding wall 11, and a lower end portion 13 below the surrounding wall 11, the surrounding wall 11 A housing space 14 is defined.

The light bar group 2 is located in the accommodating space 14 between the upper end portion 12 and the lower end portion 13 and is disposed around the mounting surface 111. The light bar group 2 includes a plurality of light emitting diodes 21 .

The photoelectric conversion unit 3 is disposed above the surrounding wall 11 and closes the upper end portion 12.

The reflector 4 is disposed on the upper end portion 12 and is attached to one side of the photoelectric conversion unit 3 away from the light bar group 2, wherein the reflector 4 has high reflectivity.

The back cover 5 is disposed above the reflector 4 and closes the upper end portion 12 , wherein the reflector 4 is interposed between the photoelectric conversion unit 3 and the back cover 5 .

The diffusing plate 6 is disposed below the surrounding wall 11 and closes the lower end portion 13. The diffusing plate 6 has an effect of interfering with light.

The light guide plate 7 is disposed at the lower end portion 13 and interposed between the light bar group 2 and the diffuser plate 6. The light guide plate 7 can guide the light transmission direction.

When the embodiment is powered on, the light bar group 2 generates a plurality of light rays 22 to be emitted away from the light bar group 2, and then a part of the light rays 221 are advanced in the direction of the photoelectric conversion unit 3, thereby directly It is absorbed and reused by the photoelectric conversion unit 3, and another portion of the light rays 222 are directly advanced in the direction of the diffusion plate 6. When the diffusion plate 6 is reached, another portion of the first partial rays 222' of the light rays 222 The diffusing plate 6 is penetrated, wherein the interference of the diffusing plate 6 prevents the first portion of the light 222' from being glare, allowing the user's vision to obtain a comfortable environment, and another portion of the light. The second portion of the light 222 222 is reflected by the diffusing plate 6 and scattered to the light guide plate 7 in a direction away from the diffusing plate 6 . At this time, the second portion of the light 222 ′′ is guided through the light guiding plate 7 . Advancing toward the photoelectric conversion unit 3 increases the probability that the second partial light 222" is absorbed by the photoelectric conversion unit 3 for reuse.

In addition, it can be understood that the light reflecting member 4 disposed between the photoelectric conversion unit 3 and the back cover 5 can absorb the light rays 221 and 222 that are not absorbed by the photoelectric conversion unit 3 and penetrate the photoelectric conversion unit 3. The transmission to the photoelectric conversion unit 3 again increases the benefit of recycling and recycling the light rays 221, 222.

It is worth mentioning that the test of the recycling process of the embodiment shows that the light energy recycling efficiency of the photoelectric conversion unit 3 can save about 10% to 20% of power, for example, if used alone The light bar group 2 is used for illumination, and needs to consume 100 watts of energy per unit time, and the embodiment only needs to consume 80 watts to 90 watts of energy per unit time, so the utility model has the functions of power saving, circulation and reuse.

Referring to FIG. 4, a second embodiment of the present invention is a second embodiment of a light-emitting cycle downlighting device. The difference from the first embodiment is that the second embodiment has a round shape and can be matched with different installations. The position is to be installed. Of course, the creation may be other shapes such as a rectangle or a diamond, and is not limited by the contents disclosed in the present specification.

In summary, the novel recessed light device with light energy circulation is that the light bar group 2 and the photoelectric conversion unit 3 are assembled into one body, and can be directly installed at a desired position (generally referred to as a ceiling), and There is no need to additionally install a photoelectric conversion device in other places, which greatly improves the convenience of the whole use, and helps to enhance the user's willingness to use. In addition, the second partial light 222 is converted to the photoelectric conversion through the light guide plate 7. The direction of the unit 3 is guided, and the light reflecting member 4 reflects the light rays 221, 222" that are not absorbed by the photoelectric conversion unit 3, thereby increasing the efficiency of the light being absorbed by the photoelectric conversion unit 3, achieving recycling and energy saving. The effect of power saving, it can indeed achieve the purpose of this new type.

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.
