Luminaire assembly with light field adjustment sheet

The present invention relates to a luminaire assembly having a light field adjustment sheet, and more particularly to a luminaire assembly that achieves the purpose of locally adjusting the light field by replacing the light field adjustment component.

In the mid-twentieth century, the advent of Light-Emitting Diode (LED) technology changed the human lighting industry and lifestyle. Compared to conventional light bulbs, light-emitting diodes are less expensive and have higher luminous efficiency. Therefore, today's conventional light bulbs are gradually being replaced by light-emitting diodes.

In order to meet the needs of various lighting equipment, the shape of the light field projected by the LED must be adjusted with different lighting requirements. For example, when the lighting device is used for close-range lighting, such as lighting a place with a small difference in height from the lighting device (for example, indoors), it is usually mainly to provide a wide range of divergent light sources because of the light. The intensity distribution is relatively uniform. Conversely, when the lighting device is used for long-distance lighting, such as lighting a place with a large difference in lighting height (such as warehouse, factory, and outdoor), it is usually mainly to provide a small range of centralized light sources. In this way, the lighting device can provide sufficient light intensity illumination for a particular area.

Please refer to the first picture. The first picture shows the first of this creation. A schematic diagram of the structure of a light-emitting component having a specific light field in the prior art. As shown, the prior art provides a lighting assembly PA1 having a specific light field, including a lighting assembly PA11 and a housing structure. The light emitting unit PA11 includes a substrate PA111 and a plurality of light emitting elements PA112. The housing structure has a housing light transmitting portion PA12 and encloses the light emitting assembly PA11. The light generated by the light-emitting element PA112 is transmitted through the light-transmissive portion PA12 of the casing.

Therefore, if the light-emitting component PA1 having a specific light field is to be irradiated with the second light field PAF2 different from the first light field PAF1, the light-emitting components PA11 of different specifications need to be replaced, so as to illuminate the second light field PAF2. purpose.

The first light field PAF1 has a first light field width PAW1 and a first light field length PAL1. The second light field PAF2 has a second light field width PAW2 and a second light field length PAL2. The first light field width PAW1 is greater than the second light field width PAW2. The first light field length PAL1 is smaller than the second light field length PAL2. At the same light intensity, since the first light field PAF1 has a wide light field width, it is suitable for a wide range of illumination at close range, such as indoor illumination. The second light field PAF2 has a longer light field length and is therefore suitable for long distance lighting such as warehouses, factory lighting and street lights.

In the light-emitting component PA1 having a specific light field provided by the prior art, different types of light-emitting components PA11 need to be prepared in order to achieve the purpose of illuminating different light fields. Therefore, in order to achieve this, it is necessary to purchase a different size of the light-emitting component PA11 at a high cost. In addition, additional space is required to place the unused light-emitting assembly PA11. In summary, after using the light-emitting component PA1 provided by the prior art with a specific light field, additional purchase cost and storage space are required.

Due to the luminaire assembly with the light field adjusting piece provided by the present invention, the related combined implementation manners are numerous, so it will not be repeated here. It is well known to those skilled in the art that this is merely an example and is not intended to limit the creation itself. The contents of the preferred embodiment of the present creation are detailed below.

Please refer to the third to sixth figures. The third figure shows a perspective exploded view of the lamp assembly with the light field adjusting piece of the preferred embodiment of the present invention. The fourth figure shows a preferred embodiment of the present invention. A perspective view of a light-emitting component in a luminaire assembly having a light field adjustment sheet; a fifth diagram showing a perspective view of a luminaire assembly having a light field adjustment sheet according to a preferred embodiment of the present invention; A schematic cross-sectional view of a luminaire assembly having a light field adjustment sheet of a preferred embodiment. As shown, in a preferred embodiment of the present invention, a luminaire assembly 1 having a light field adjustment sheet is provided, including a illuminating assembly 11, at least one light field adjustment component 12, and a luminaire housing 13.

The light-emitting component 11 includes a substrate 111 and a plurality of light-emitting elements 112. The substrate 111 extends along an extending direction S, and has a light emitting surface 1111 and a backlight surface 1112, and four light exiting regions 1111a, 1111b, 1111c, and 1111d are defined on the light emitting surface 1111. The plurality of light-emitting elements 112 extend in the extending direction S to form the four light-emitting regions 1111a, 1111b, 1111c, and 1111d, and each of the light-emitting elements 112 projects an illumination beam along a light-emitting path. Preferably, the light-emitting element 112 is a Light-Emitting Diode (LED).

The light field adjusting component 12 selectively covers a portion of the four light exiting regions 1111a, 1111b, 1111c, and 1111d along the extending direction S, thereby partially covering the light emitting surface 1111. For example, the light field adjusting component 12 may cover only the light emitting region 1111a and the light exiting region 1111c, thereby forming a specific light field after the illumination beam passes. Of course, the light field adjusting component 12 can cover at least one of the four light exiting regions 1111a, 1111b, 1111c, and 1111d in an array to form different light fields after the illumination beam passes. The light field adjusting component 12 includes a light field adjusting sheet body 121 and at least one light field adjusting light transmitting structure 122. The light field adjusting light transmitting structure 122 is disposed corresponding to the light emitting element 112 to the light field adjusting sheet body 121 corresponding to the light exiting path. Further, when the number of the light field adjusting elements 12 is plural, the light field adjusting element 12 covers the light emitting surface 1111 in the extending direction S. Incidentally, different types of light field adjusting elements 12 can be formed by varying the number of light-transmitting structures 122 on the light field adjusting element 12.

It is further explained that the light field adjusting light transmitting structure 122 is a convex structure. More specifically, the convex structure is a light collecting structure, and the light collecting structure is usually a hemispherical structure or a semi-elliptical structure. However, the shape of the concentrating structure is numerous, so it will not be repeated here. The light field after the illumination beam passes through the light field adjusting transmission structure 122 can be changed by changing at least one of the material of the concentrating structure and the focal length. In fact, changing at least one of the material of the concentrating structure and the focal length will result in different types of light field adjusting elements 12. It is worth mentioning that the light field shape of the illumination beam projected by the self-luminous element 112 is adjusted by the light field adjusting light transmitting structure 122.

In summary, when the light field adjusting component 12 having the at least one light field adjusting light transmitting structure 122 is covered on the light emitting component 11, the light field adjusting light transmitting structure 122 is correspondingly covered by the light emitting component 112, so that the light field of the illumination beam is received. The light field adjusts the adjustment of the light transmitting structure 122. It is worth mentioning that the light field adjusting element 12 can be covered by the light-emitting component 11 at intervals to each other to adjust the light field of the illumination beam projected by the partial light-emitting element 112. Wherein, when at least one of the light field adjusting elements 12 is arranged, different spacing distances between the two are formed to form different arrangements.

The lamp housing 13 encloses the light-emitting assembly 11 and the light field adjustment component 12. The luminaire housing 13 includes a first housing structure 131 and a second housing structure 132. The first housing structure 131 is disposed adjacent to the light emitting surface 1111. The second housing structure 132 is disposed adjacent to the backlight surface 1112. By the way, the first housing structure 131 is a light transmitting structure, and the second housing structure 132 is a heat dissipation structure. It should be noted that the illumination beam projected by the illuminating element 112 penetrates the first housing structure 131, that is, the illumination beam projected by the illuminating element 112 penetrates the light transmitting structure.

In addition, the second housing structure 132 contacts the backlight surface 1112 of the substrate 111. The substrate 111 conducts heat to the second housing structure 132 for heat dissipation through the second housing structure 132. Preferably, the second housing structure 132 is made of a material having better thermal conductivity, such as an aluminum alloy. The second housing structure 132 has a wide variety of materials, so it will not be described here.

Specifically, when the light-emitting element 112 projects an illumination beam along the light exit path, the light field shape of the illumination beam is adjusted by the light field adjustment light-transmitting structure 122. Finally, the illumination beam is projected via the first housing structure 131.

Please refer to FIG. 4 and FIG. 7 together. FIG. 7 is a schematic diagram showing the light field correction of the lamp assembly with the light field adjusting piece according to the preferred embodiment of the present invention. As shown in the figure, the illumination beam projected by the luminaire assembly 1 having the light field adjustment sheet has a first light field F1 and a second light field F2 at the same illumination intensity. Because the illumination beams projected from the different light exit regions 1111a, 1111b, 1111c, 1111d have different light fields. Here, only two light fields are taken as an example for simply explaining the embodiment, and the actual operation is not limited thereto. In the first light field F1, there is a first light field width W1 and a first light field length L1. In the second light field F2, there is a second light field width W2 and a second light field length L2. The first light field width W1 is greater than the second light field width W2, and the first light field length L1 is smaller than the second light field length L2.

It is further explained that the first light field F1 is generally a light field pattern for setting a lighting device of a lower height (for example, indoor) because the range of illumination required is a wide angle and the irradiation distance is short. The first light field F1 is, for example, a light field of a fluorescent lamp, and the first light field F1 has a wide variety, so it will not be described here.

It is further explained that the second light field F2 is generally a lighting device for setting a place with a high height (warehouse, factory, and outdoor) because the range of illumination required is small, and the irradiation distance is required to be far. The second light field F2 is, for example, a light field of a projection lamp. There are many types of the second light field F2, so they are not described here.

In general, when the illuminator assembly 1 having the light field adjustment sheet simultaneously illuminates the illumination beams of the first light field F1 and the second light field F2, the first light field F1 and the second light field F2 are corrected to a correction. Light field F3. The corrected light field F3 has a corrected light field width W3 and a corrected light field length L3. The corrected light field width W3 is between the first light field width W1 and the second light field width W2, and the corrected light field length L3 is between a first light field length L1 and a second light field length L2.

In this way, the corrected light field F3 can be indirectly corrected by adjusting the first light field F1 and the second light field F2 by adjusting at least one of the number, arrangement, and type of the light field adjusting elements 12. An ideal light field shape. In other words, the corrected light field F3 can be regarded as a light field composed of the first light field F1 and a second light field F2. Therefore, the correction light field F3 can be adjusted by adjusting at least one of the first light field F1 and the second light field F2.

In summary, in the lamp assembly with the light field adjusting piece provided in the preferred embodiment of the present invention, at least one of the number, arrangement and type of the light field adjusting elements can be adjusted to illuminate An ideal light field shape. In this way, not only the light field pattern illuminated by the luminaire assembly having the light field adjustment sheet can be freely adjusted, and no additional illuminating assembly is required. Compared with the prior art, the present invention faithfully saves the cost caused by purchasing different specifications of the light-emitting components, and also reduces the space required for storing the light-emitting components.

The features and spirit of the present invention are more clearly described in the above detailed description of the preferred embodiments, and the scope of the present invention is not limited by the preferred embodiments disclosed herein. Various other modifications and changes can be made by those of ordinary skill in the art. However, all the improvements and changes made in accordance with the present embodiment are still in the present. The spirit of creation and the scope of the definition of the patent.
