BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention relates to a LED projecting lamp structure provided with a white light
LED featured with a low weight, a small volume, a wide-angle irradiation, a low attenuation,
being assembled with several fixing mount comprising a flank fixing rack, a top-and-bottom
fixing rack, a revolving padlock, a three-way padlock, a three-way rack, a T rack,
a four-way rack, a lengthwise rack, and several link mounts comprising a middle-piece

2. Description of Related Art
[0002] A conventional projecting lamp unit is generally provided for a traffic sign and
an advertisement board that projects upwards or downwards, frequently being used with
a halogen cup lamp or a halogen strip lamp or a halogen bulb. The halogen lamp is
lower in price, longer in service life, and higher in brightness and efficiency than
a tungsten lamp, may prevent filamentary cathode from splitting early, and may be
electrified in a higher temperature to illuminate, thereby the brightness and efficiency
being higher. The halogen lamp is covered with a silica glass of which a melting point
is higher; a normal glass is not adapt for a higher temperature condition, so it is
inferior in the capability of UV blockage.
[0003] Consequently, because of the technical defects described above, the applicant keeps
on carving unflaggingly through wholehearted experience and research to develop the
present invention, which can effectively improve the defects described above.
[0004] It is a drawback in a bulb of a conventional projecting lamp unit that it generates
an optical energy converted from an electric energy, in which around 5% of the optical
energy is occupied from the optical energy, and 95% of the optical energy is converted
into a heat energy that is not needed; thus, the power is consumed very much, and
the power must be supplied remotely for generation of the light source in great quantity.
[0005] A further drawback in the state of the art is that a predetermined supporting capability
must be applied to the conventional projecting lamp unit to bear the weight of a bulb
seat and a bulb, so a structure of a certain volume must be provided to bear the weight
of a pressure applied by the bulb seat and bulb; an issue of affecting a line of sight
also occurs.
[0006] The bulb light is emitted from an interior to an exterior in a form of sphere. Hence,
it is a further drawback in the state of the art that, when a ray of light reaches
a plane, the intensity of illumination is certainly uneven. In order to repair the
defect, the bulb that is located must be added in amount, wherein the cost of bulb
increases.
SUMMARY OF THE INVENTION
[0007] It would be desirable, therefore, to use an LED lamp featured with a low voltage,
a low current, and a low conversion loss and match them with a solar power panel or
a small windmill as a power accumulator for achievement of self-power-saving, wherein
no extra power supply being required.
[0008] It would be further desirable to distribute the LED light on a long thin lamp rack
unit. The volume of said lamp rack unit occupies a small area, so the board surface
is easily recognized from a distance, thereby a degree of recognition of the board
surface being not affected and the ray of light given by the projecting lamp being
even.
[0009] It would be further desirable if several fixing racks are spirally locked and fixed
at a rear of a large billboard, and thus the structure is formed with several flank
fixing racks, a top-and-bottom fixing rack, a middle piece rack, several revolving
padlocks, a two-way padlock, a three-way padlock, several three-way racks, a T rack,
a four-way rack, a lengthwise rack, and a link mount.
[0010] It would be further desirable if several lamp rack units are locked to and provided
in the structure for the white-light LED projecting lamp unit to be arranged in an
area of projection. Compared with the conventional projecting lamp unit, this may
save more power, make the illumination even, and serve longer in a condition of equal
area and illumination for achievement of wide illumination.
