AN OUTDOOR LIGHT
TECHNICAL FIELD
[0001] The present disclosure described herein, in general, relates to LED outdoor light, and more particularly the LED outdoor light that uses LED as a light source and attach the base body with the heat sink through insert moulding technique so that there is no air gap between the base body and the heat sink and thus reduce the thermal resistance between the LED and the outer heat dissipating surface which help in efficient heat dissipation or management.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[0003] In general, an outdoor light is a lighting facility installed along the street for the safety and security of the street. It is composed of a pillar and a streetlight head that is installed at the end of the pillar. An electric lamp is provided inside the street lamp head, and the town is illuminated by the light emitted from the lamp.
[0004] A floodlight is also a type of outdoor light. It is a broad-beamed, high-intensity artificial light. They are often used to illuminate outdoor playing fields while an outdoor sports event is being held during low-light conditions. More focused kinds are often used as a stage lighting instrument in live performances such as concerts and plays.
[0005] In the top tiers of many professional sports, it is a requirement for stadiums to have floodlights to allow games to be scheduled outside daylight hours. Evening or night matches may suit spectators who have

work or other commitments earlier in the day, and enable television broadcasts during lucrative primetime hours. Some sports grounds which do not have permanent floodlights installed may make use of portable temporary ones instead. Many larger floodlights will have gantries for bulb changing and maintenance. These will usually be able to accommodate one or two maintenance workers.
[0006] Since outdoor lights often use general bulbs, their service life is short and their impact resistance is also reduced. Recently, high-luminosity LEDs (light-emitting diodes) with excellent impact resistance while their service life has been greatly extended.
[0007] A conventional LED street/flood light that are available in market with main body that completely made up of metal (mostly in casting process) & for this type of design, a driver should be isolated from main body due to safety concern of users, so, due to which electronics design solution should be isolated type.
[0008] In electronics, a driver is a circuit or component that is used to control another circuit or component, such as a high-power transistor or MOSFET, inductors, and numerous others. They are usually used to regulate current flowing through a circuit or to control other factors such as other components, some devices in the circuit. The term is often used, for example, for a specialized integrated circuit that controls high-power switches in switched-mode power converters. An amplifier can also be considered a driver for loudspeakers, or a voltage regulator that keeps an attached component operating within a broad range of input voltages. Hence, there is a need to isolate the driver from the main body due to the safety concern of the user.
[0009] Also, some low cost conventional LED street/Flood light use plastic body and simply put the aluminium or metal plate inside and then mount the MCPCB on these plates to work as heat sink. These metal plates are inside the plastic cover. There is air gap between the metal

plate and the plastic outer body. This air gap works as an insulation and resist the heat transfer to the outer plastic body. Therefore, the conventional light uses an inefficient way of heat management.
[0010] Moreover, the conventional outdoor light has rough surface finishing, low production efficiency, complex in design, high waste & high labour cost. The above-mentioned are the disadvantage of metal type flood light & street light during casting & production.
[0011] In addition, complex & feature based design are not feasible with metal type street/flood light, also it has glass or optics-based diffuser which can break & also relatively hazardous to nature.
[0012] Hence, there is a need of an outdoor LED light that overcomes all the problem associated with the conventional outdoor light.
[0013] In view of the above, there is a need of an outdoor light which uses the technique such as insert moulding so that there is no air gap between the plastic body and the internal heat sink and thus reduce the thermal resistance between the LED and the outer heat dissipating surface.
[0014] Moreover, there is also a need of an outdoor LED light having a structure that is simpler and more inexpensive to make, and which can easily be attached to the lamp post to eliminate the existing above-mentioned problems.

[0051] FIG. 1 illustrates an exploded front view of the outdoor LED light specifically floodlight in accordance with an embodiment of the present disclosure;
[0052] Both of the outdoor LED light (streetlight and flood light) comprises the same components. The outdoor LED light 100 of the present disclosure comprises a base body 102 having an opening to establish an electric connection. The base body 102 is made of plastic and the heat sink 104 made of aluminium or other metal that is placed inside the base body 102 through insert moulding technique and then MCPCB 106 is mounted on the base body 102. Precisely, the heat sink 104 is placed inside the base body 102. Hence, there is no air gap between the heat sink 104 and the plastic base body 102 and thus reduces the thermal resistance between the LED and the outer heat dissipating surface.
[0053] The MCPCB 106 comprises a plurality of LED 108 that are being attached to the top of the MCPCB 106.
[0054] Traditionally, the MCPCB is mounted on the heat sink body by using many numbers of screws on the MCPCB. In direct screw mounting

system, die-electric break of MCPCB is also an issue many times, if by chance worker on line tight the screw with high force directly on the MCPCB then, there is great chances of scratch over MCPCB, in long term which may leads to die-electric break down.
[0055] But, in the present disclosure, the MCPCB 106 is pressed uniformly on all edges via the reflector 110 having a hole 112 at the centre to accommodate the MCPCB 106 effectively. This gives uniform pressure on the MCPCB 106 and the heat sink body 104 and also avoid use of extra screws which lead to improvement of heat management and also reduce extra process and materials.
