Project Name: Astra Series Indoor Track Light Ceiling Lights

Reporting unit: Delta Electronic Industry Co., Ltd.

Comprehensive introduction or reporting reasons:
● Astra series lamps are designed to meet the needs of the market for large-area uniform lighting such as wall coverings, product shelves, menu boards or other related commercial applications. Through the patented optical module of ultra-short-focus projection optical technology, the light is evenly distributed to all corners of the rectangular illuminated area, and the light is installed at a position one meter away from the wall to achieve a light distribution of 6 m in width and 3 m in height.
● At present, most commercial spaces use projection lamps to illuminate large areas of flat objects (such as menus and paintings), but most traditional projection lamps have an illumination angle of between 15 and 60 degrees. When the object to be photographed is large (wide), it is necessary to use a plurality of projection lamps to overlap the light-emitting area to expand the illuminated area to reduce the dark area. However, the illumination design using overlapping illumination may cause the brightness of some areas to be too high, which may cause the subject to be distorted and cause excessive refraction problems, and at the same time generate waste of lamps and energy.
● Use Astra series luminaires to reduce the use of energy to reduce the number of lamps, and provide a simple calculation method. Users can know how long the luminaire should be installed from the object according to the long width of the exposed area.
● Astra series lamps can provide a large area of evenly distributed illumination effect, not only can meet the illumination needs, but also provide good light quality, so that consumers can have a more comfortable lighting experience in commercial space.

Economic evaluation analysis:
This product can effectively improve the current poor optical design of LED projection lamps, drive industrial technology upgrades, and develop new blue ocean market. It is estimated that the sales volume of lamps will reach 30 million US dollars within three years.

Technical and process innovation points:
The optical design of the product is such that the light of the light source is projected onto the light receiving surface to form a rectangular spot, and the light projected by the boundary curve of the upper surface is the boundary position of the rectangular spot, and the lower surface and the upper surface are slightly coaxial. Axisymmetric surface. The side surface surrounds between the upper surface and the lower surface, and the light source is overlapped and projected on the corresponding position of the rectangular spot; the light projected through the boundary curve of the side surface is projected on the boundary of the rectangular spot, and the side surface is The light projected inside will be projected within the boundary of the rectangular spot to enhance the illumination of the rectangular spot. Finally, a high-efficiency short-focus wide-angle floodlight product was developed.
