(a) Field of the Invention
The present invention is related to an all-around LED light, and more particularly to a light emission unit comprised of multiple light emitting diodes arranged in a circular fashion and a concave panel, the concave panel being related to a parabolic mirror made in a proper curvature according to relative location of a single LED and light streams being reflected by the parabolic mirror to outward radiate and scatter.
(b) Description of the Prior Art
All-around lights generally available in the market emit light by heating a filament in a light bulb to generate thermal energy far greater than optical energy produced. Accordingly, temperature of the peripheral to the all-around light will become extremely high to warrant protection from a container with high heat resistant property to avoid burning from human contact or damaging surface glass. The light bulb containing the filament is usually secured in place by a thread disposed at the lower end of the light bulb and the light bulb must be replaced with a new one once the filament gets thinner and eventually burnt out. The prior art is found with the following defects:
1. The all-around light of the prior art works with the light bulb as the primary light emitting object by converting electric energy to present in the forms of light and heat and only up to 5% of energy converted are capable of radiating the light in a spherical form while the rest of the energy are converted into useless thermal energy resulting in short service life, heat generation, excessively power consumption, and being vulnerable to break.
2. Replacing the bulb only can be done when the temperature to the peripheral of the bulb cools down to ambient temperature or an aid of certain object or tool must be used resulting in waste of time and increased difficulty in replacement.
3. There is usually only one light bulb mounted in the all-around light of the prior art; once the light bulb is damaged or fails, the safety is immediately compromised when the ship is steering during night or misty hours.
The primary purpose of an all-around LED light of the present invention is to provide an LED bulb to correct those defects found with the prior art.
To achieve the purpose, a locating disk is disposed with multiple light emitting diodes arranged in a circular form with a locating hole and a first bolting hole at the center that correspond to a screw hole on a locating base and a bolt from a bolting base. A reflection mask related to a reflective wall is comprised of multiple concave panels having a same curvature abutted to one another, and a flat board is connected to a lower end of the reflection mask for both of the reflective mask and the flat plate to take a shape of a bowl. A fixation holder is disposed at a center of the flat plate and a directional holder extends from a side of the fixation holder; and a second bolting hole penetrate through in relation to where a bolting pillar on the bolting holder is located. Both of the second bolting hole and the bolting pillar by locating to each other facilitates each LED to adapt to a concave panel for the LED to radiate light streams to its surroundings. LED for featuring power saving, long service life, and free of generating heat provides much higher value of operation benefits than a light bulb.
A bottom of the locating disk rests on the locating holder and upper ends of two bolting holders to indicate a suspended status. A bolt from a bolting holder disposed on a base of the all-around LED light penetrates upward into the first bolting hole of the locating disk, and two locating screws downward penetrate through respectively locating hole to fasten in the locating holder to constitute a semi-product of a structure of the present invention. The reflective mask is contained in a lampshade to form an inverted taper holding against the fixation holder with the directional hold locked into a directional groove. A fixation screw penetrates an lower end of the inverted taper to fasten into the fixation holder; and a face cover covers up and clicks on the lampshade to constitute another semi-product of the structure of the present invention. Both semi-products are located by having the bolting pillar on the bolting holder to penetrate through the second bolting hole on the reflective mask and clicked in position by the lampshade and multiple circular ribs disposed on the base in an intrigue relationship of mutual containment. Whereas the LED in operation will not generate heat, it takes only to disengage the upper semi-product from those circular ribs disposed between a locating board and the upper semi-product and to loosen up those locating screws of the lower semi-product upon replacing the locating disk to save time and achieve convenient replacement.
A basic light emitting unit disposed on the locating disk is comprised of an LED and its respective concave panel from the reflective mask. By taking advantage of the concave panel that indicates a parabolic mirror, which is made with a proper curvature by compromising the location of the LED. Reflected light streams scatter outwardly, and multiple light emitting units arranged in a circular form to radiate light streams to their surroundings. Whereas each LED features high luminance, any single LED when damaged or fails will not affect normal operation of other LEDs to continuously emit light streams in a luminance much higher than that of the regular bulb to provide the function of luminance supplementation while maintaining a all-around light with uninterrupted efficacy.
Emitting a single color light is one of the features of the LED and the LED is capable of emitting light streams in a color as designed without relying upon changing the color of a casing. Multiple locating disks with each emitting a selected color different from that emitted from other locating disk for alternating among colors depending on the sailing situation to achieve practical economic benefits.

As illustrated in
Emitting a single color of light is one of the features of the LED and the color of the light varies depending on frequency and wave length. The color of the light emitted from the LED therefore can be selected as required for the present invention to allow change of light color by direct replacement of the locating disk for providing general economic benefits.
The present invention by having arranged multiple light emitting diodes 31 in a circular form and by taking advantage of the parabolic surface of the reflective mask 5 to change routes of light emission for scattering light emission to the surroundings in substituting the conventional light bulb while having its composition elements to form mutual containment by lateral locating inside and longitudinal clicking outside provides benefits of convenient replacement and higher use safety; therefore the application for a utility patent is duly filed accordingly.
