ABSTRACT:
BACKGROUND OF THE PRESENT INVENTION
1. Field of Invention
The present invention relates to a light source arrangement, and more particularly to a high intensity light source arrangement which can enhance brightness of emitting light and increase the cooling effect of the light source arrangement while using low current and voltage.
2. Description of Related Arts
Nowadays, the most common light sources are filament lamp bulb for illumination and LED lighting for indication. Due to the remarkable features of low power consumption and instant light emission. LED lighting is specially adapted to be utilized in many electrical appliances as signal and indicating lighting, such as the power on-off signal light and instructional signal light of electric equipment, indicating light of electronic clock, and etc. . . .
Although the LED has excellent properties of low power consumption and instant light emission, the relatively small light intensity and lighting emission angle of the LED make it not suitable to use for illumination or even apply in some specific area such as traffic light, signboard light vehicle brake light and signal light, and airport guiding lighting.
In order to increase the light intensity of the LED, a larger current can be applied to the LED so as to increase the electrical power thereof. However, due to the structure of the LED. when increasing the current, heat generated from the LED will burn the LED.
In addition, the major drawback of the LED is that the LED cannot produce white light. It is known that white light is composed of red, blue, and green lights. A single LED is capable of producing red, blue, and green lights individually but not the daily used white light.
In order to produce a white light, an improved LED comprises a blue zinc luminary element and a fluorescent layer powdered on an inner surface of a reflexive cover, wherein when light is produced by the luminary element and reflexed on the fluorescent layer, the white light is produced. However, the fluorescent layer cannot be evenly applied on the inner surface of the reflexive cover so that the white light will not be evenly dispersed from the reflexive cover so as to provide an uneven intensity of the white light.
SUMMARY OF THE PRESENT INVENTION
A main object of the present invention is to provide a high intensity light source arrangement which can prolong the service life span of the high intensity light source arrangement by better dissipating and reducing the heat generated.
Another object of the present invention is to provide a high intensity light source arrangement which greatly increases the brightness of the light emitted, wherein the light source arrangement is capable of providing a light intensity up to five times or more of a conventional LED.
Another object of the present invention is to provide a high intensity light source arrangement which comprises a heat dissipation unit directly mounted underneath a circuit board for efficiently dissipating heat therefrom. Therefore, a plurality of luminary elements is capable of electrifying with the terminals on the circuit board.
Another object of the present invention is to provide a high intensity light source arrangement adapted for producing a white light by selectively arranging the luminary elements of the luminary unit.
Another object of the present invention is to provide a high intensity light source arrangement adapted for selectively controlling the color of the light from the luminary unit.
Another object of the present invention is to provide a high intensity light source arrangement wherein a fluorescent layer is evenly coated on an inner surface of a head cover of the high intensity so as to enhance the white light evenly dispersed therefrom.
Accordingly, in order to accomplish the above objects, the present invention provides a high intensity light source arrangement, comprising:
a luminary unit comprising a luminary circuit, at least a terminal electrically connected to the luminary circuit, and at least a luminary element adapted for electrifying with the terminal to emit light;
a heat dissipation unit supporting the luminary unit and dissipating heat generated from the luminary unit; and
a base housing for supporting the heat dissipation unit thereon comprising an electric input connector electrically connecting to the luminary unit.
