Color cover/change/mixture structure of light bulb/tube/fixture

A color cover/change/mixture structure of a light bulb/tube/fixture includes an enclosure, a base, a cold cathode fluorescent lamp tube, and a color cover. The enclosure is a tubular body having a non-light-transmitting or light-transmitting top and a light-transmitting bottom. The base has a bottom surface having retention pawls for engaging and retaining the cold cathode fluorescent lamp tube. The cold cathode fluorescent lamp tube, after combined with the base, is disposed and mounted in the enclosure. Heads are mounted to two ends of the enclosure. The color covers have different colors and are selectively mounted to the enclosure to change the color of light emitting from the cold cathode fluorescent lamp tube.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to an improved structure of a light fixture, which involves various color covers to allow the light fixture to generate multiple sections of different colors of irradiation light so that with such a structure of the light fixture applied to indoor plant cultivation, plants can be irradiated with irradiation light of different color spectra to timely supplement supply of light of all necessary color spectra to the cultivated plants during each phase of growth of the plants in order to achieve better, or even the best, result of growth.

DESCRIPTION OF THE PRIOR ART

Due to the progress of science and technology and the upgrading of living quality of people, indoor plant cultivation is now a new trend of planting ways and is even applied to plant factory for mass cultivation. Such indoor cultivation of plants, such as vegetables and fruits, is achieved by using a traditional fluorescent light tube or an energy saving bulb or an LED light to replace illumination achieved with sunlight for inducing photosynthesis of the plants. Besides the traditional fluorescent light tubes, energy saving bulbs, and LED lights, lighting may also be achieved with a cold cathode fluorescent lamp tube based light fixture, of which the performance is similar to those of the traditional fluorescent light tubes, energy saving bulbs, and LED lights. However, for the cold cathode fluorescent lamp tube based light fixtures or the traditional fluorescent light tubes, energy saving bulbs, and LED lights that are currently available in the market, whether they are light sources of a tubular form or a bulb form or are projection lamps or planar (panel) lamps or even other types of light fixtures, they all generates light of a single color for irradiation and it is not possible to supply different spectra of light or even to simultaneously supply multiple sections of light color spectra for change or mixture for irradiation of the light to the plants so that the plants may receive supplemental supply of all color spectra that are necessary for photosynthesis during all stages of growth of the plant for better or even the best result of growth. Thus, such a cold cathode fluorescent lamp tube based light fixture is only good for regular lighting and illumination and if it is used for indoor cultivation of plants, further improvements of the structure of such a cold cathode fluorescent lamp tube based light fixture would be necessary.

SUMMARY OF THE INVENTION

The conventional cold cathode fluorescent lamp tube based light fixture generates only a single color of light and this does not allow for irradiation of plants with various color spectra of light or change or mixture of multiple different color spectra of light in order to supply supplemental color spectra that are necessary to the growth of the plants in a timely manner in each of the stages of growth of the plant for achieving better or even best result of growth.

The present invention provides a color cover/change/mixture structure of a light bulb/tube/fixture, of which an illustrative example is a light fixture having a light source formed of a cold cathode fluorescent lamp tube, which generally comprises constituent components including an enclosure, a base, a cold cathode fluorescent lamp tube, and one or multiple color covers. The enclosure is a tubular body having a non-light-transmitting or light-transmitting top and a light-transmitting bottom. The enclosure is provided, in an interior thereof, with grooved track on two opposite sides. The base is a flat plate body having a bottom surface to which retention pawls are formed for engaging and retaining the cold cathode fluorescent lamp tube on the base the bottom surface and is disposed, after being combined with the cold cathode fluorescent lamp tube, inside the enclosure in such a way that two opposite edges of the plate body are respectively received and retained in the grooved tracks of the two sides of the interior of the enclosure. A head is then coupled to each of two ends of the enclosure to form a light tube based light fixture. The color covers are annular light-emitting elastic long/short covers having a proper size and is close to or slightly greater than a semi-circular configuration or are cylindrical sleeve-like annular light-transmitting elastic long/short covers so that a single one or a plurality of color covers of different colors may be coupled to a bottom surface or a light-transmitting surface of the enclosure or sleeve may directly fit over the enclosure.

The present invention provides a color cover/change/mixture structure of a light bulb/tube/fixture, which involves a single one or a plurality of color covers of different colors that are clamped to or directly fit over a bottom surface or a light-transmitting surface of the enclosure to allow vegetables/fruits planted in various sections of an indoor area to receive, in addition to the basic light spectrum emitting from a color light tube, supplemental supply of necessary light spectra provided by each of the color covers so that the light fixture may generate multiple sections of different colors or provide various irradiation light colors at the same time within an extremely small, fixed area with a single light source, allowing the plant growers to determine and select, among the color covers, desired ones of the covers having desired colors according to experiences or public knowledge available from agricultural books. With a cold cathode fluorescent lamp tube based light fixture of such a structure applied to indoor cultivation of plants, the plants may receive irradiation of light of different spectra and supplemental supply of various light spectra that are required for different stages of plant growth can be achieved to ensure better or even the best result of growth of the plants.

The present invention provides a technical solution that is illustrated with a light fixture that involves a cold cathode fluorescent lamp tube as a light source, but is not limited such a light fixture. Light fixtures that are provided for illumination and lighting can be modified with the embodiments disclosed in the present invention by incorporating the color covers with light bulbs, light tubes, and light fixtures, which are all covered and protected with a patent sought for the present invention.
