1. Field of the Invention
The present invention relates generally to a lamp, and more particularly to an innovative one which is used for light steel frame thanks to its advantages such as: energy conservation, environmental protection and improved illuminance.
2. Description of Related Art
The fluorescent lamps are generally used as lighting sources for everyday life and transaction activities of the people.
To meet the home or office environment, the fluorescent lamp is often installed in a lightweight steel framework, thus forming a lightweight steel frame lamp. A plurality of fluorescent lamp tubes are embedded into a recessed portion of the steel frame, and electrically connected with the power supply module. As such, the heavy metal—mercury contained in the lamp tube will be activated to generate energy, which is converted into light source penetrating the aforementioned lamp for illumination.
However, this typical lightweight steel frame lamp shall be improved due to its environmental pollution caused by the mercury contained thereof, as well as excessive power consumption.
The primary objective of the present invention is to provide a lightweight steel frame lamp for energy conservation and environmental protection & preservation.
Another objective of the present invention is to provide a lightweight steel frame lamp for higher degree of illuminance.
For these purposes, the lamp for lightweight steel frame comprising:
a first frame, containing a power supply module at the back, at least two heat sinks at both sides of the power supply module, and a conductor for electrical connection with the power supply module;
at least a LED assembly mounted in front of the first frame; the LED assembly is electrically connected with the conductor to form a spotted light source;
at least a reflector used to convert the spotted light source into directional beam for projection into external environment; the reflector is installed within the front of first frame;
a second frame, defining a space for covering the first frame;
two diffusers arranged between the reflector and substrate, as well as a condenser between the diffusers.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
Referring to
a first frame 1, containing a power supply module 11 at the back, at least two heat sink units 12 at both sides of the power supply module 11, and a conductor 13 for electrical connection with the power supply module 11;
at least a LED assembly 2 mounted in front of the first frame 1; the LED assembly 2 is electrically connected with the conductor 13 to form a spotted light source;
at least a reflector 7 used to convert the spotted light source into directional beam for projection into external environment; the reflector 7 is installed within the front of first frame;
a second frame 5 in the lightweight steel frame 6, defining a space 51 for covering the first frame 1 from down to up. So, several elements could be accommodated between the first frame 1 and the space 51, but at least a heat sink unit 12 is not covered to ensure that the heat sink unit 12 could still be operated.
Furthermore, the preferred embodiment of the lamp for lightweight steel frame also comprising: a transparent substrate 3 arranged between the bottom of reflector 7 and the second frame 5. It is worthy to note that, the substrate 3 is made of glass or acryl plate. In this preferred embodiment, the substrate 3 is made of acryl plate.
The heat sink unit 12 could discharge the heat energy generated by LED assembly 2.
LED assemblies 2 are symmetrically arranged at both sides of the first frame 1 for forming horizontal beam. A flexible color scheme is made possible for LED assemblies 2 since beams of different colors are emitted.
The second frame 5 is sized bigger than the first frame 1, so both frames could be assembled smoothly.
Two diffusers 8 may be arranged, if necessary, between the reflector 7 and the substrate 3, and a condenser 9 is arranged between the diffusers 8 to improve the illuminance. In such case, the substrate 3 could be made of thin-profile materials for lightweight design.
The first frame 1 is made of reinforced materials. In this preferred embodiment, the first frame 1 is made of metal material.
The first frame 1 in this preferred embodiment is designed into a rectangular shape, so the inner space of the present invention can be saved.
The second frame 5 is made of reinforced materials. In this preferred embodiment, the second frame 5 is made of metal material.
The second frame 5 in this preferred embodiment is designed into a rectangular shape, so the inner space of the present invention can be saved.

As shown in
Referring to
As compared with typical lightweight steel frame lamp, the present invention has the following advantages:
1. Lower power consumption/maintenance cost and longer service life for LED assembly; the power consumption could save up to 60%-90%, and LED assembly could be activated rapidly in low-voltage environment.
2. LED assembly doesn't contain mercury, without the hazard of environmental pollution.
3. The illuminance could be further improved with additional installation of diffuser and condenser.
On the other hand, the present invention also has the following characteristics:
1. The reflector could convert the spotted light source of LED assembly into directional beam.
2. A flexible color scheme is made possible for LED assemblies.
3. The first and second frames could be designed in a manner to save the space, resist the shock and compression.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
