TECHNICAL FIELD
[0001] The present disclosure, in general, relates to an illuminating device. In
particular, the present disclosure relates to an illuminating device having an internal
reflector that facilitates uniform light distribution in area where light is required.
BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the
information provided herein is prior art or relevant to the presently claimed
invention, or that any publication specifically or implicitly referenced is prior art.
[0003] The illuminating device is having property to provide lighting in various
direction. Lighting includes the use of artificial light sources like lamps, light
fixtures and the like. The illumination device may include the light source such as
Light Emitting Diode (LED) or any other electronic device applicable in differe nt
areas. Further, a brief about the LED is discussed herein below.
[0004] LED devices are more efficient than most forms of widely used lamps,
for example, incandescent, high-intensity discharge (HID) light sources, and the
like. One advantage of using LED devices is that LEDs are more efficacious than
incandescent light and more efficacious than some fluorescent and low wattage HID
light sources. Another advantage of LED device usage is that the LEDs may be configured as low voltage, low energy devices. Another advantage of the LED devices is that of the longer life when compared to other light forms.
[0005] In LED illuminations, heat transmission and its management during the
operation of a LED bulb is always a major concern. The conventional systems of
existing LED bulb are designed in such a way that most of the components are
mounted on a metal core printed circuit board (MCPCB) and/or below the MCPCB

higher compared to the ambient temperature over the MCPCB area where Optics/ Diffuser is installed, due to which the operating temperature of the electronic parts is much higher thus limiting and reducing the life time of the electronics parts.
[0006] Further, along with heat management, it becomes necessary that the device is cost-effective, easy to assemble and capable of mass production in order to meet the large market demands as compared to the conventional DOB LED bulbs available in the market.
[0007] In tradition, the electronic parts are mounted on a LED lamp, where the ambient operating temperature of the critical parts like ELCO, MOV is higher and further creates the problem of longevity of the various electronic component parts. Further, the design of the LED lamp is such a manner which may harm the human eyes during direct exposer of the lamp. In addition to this, the traditional lamp does not provide uniformly in-terms of desired beam angle due to typical directional nature of LED, which is required to direct the light in the desired area.
[0008] Therefore, there is a need for such a device with reflector which can overcome the above-described limitations and obtain maximum operating efficiency in a cost-effective manner which is unique in its design and exhibits prime quality for use over a sufficient period of time.

[0012] It is still another object of the present disclosure to ensure uniform light distribution at application area by using the reflector which divert the light sideways.
[0013] It is yet another object of the present disclosure to reduce the ambient temperature around the critical parts (electronic component) fixed on the MCPCB board of said device by around 20%.
[0014] It is still another object of the present disclosure to provide a unique configuration of said device wherein all the electronic components mounted on the MCPCB, wherein said all the electronics components of MCPCB are hidden inside the reflector, due to which the temperature of the critical parts of MCPCB may be reduced about 20%.
