Description

Technical Field

[0001] The present invention relates to an LED lamp with a narrow beam angle and a floating deflector. More specifically, the present invention relates to an LED lamp of the AR111 and AR70 types having a narrow beam angle between 6° and 7° and a floating deflector for reducing glare.

[0002] This new structural configuration reduces the beam angle through an embedded floating deflector placed close to the light source and redirects the light to the reflector to minimize glare. In addition, the LED lamp is characterized by a continuous geometric shape in its body. Background Art

[0003] AR lamps are available with beam angles of 12° and 24° and are categorized as AR111 and AR70. They are suitable for a variety of applications, particularly for creating scene lighting and accent lighting. The model number corresponds to the lamp diameter, with the AR70 suitable for standard ceiling heights of 3 meters and the AR111 for higher ceiling heights of double height.

[0004] The AR light has a configuration where the LEDs are hidden and the light source is invisible in order to reduce glare.

[0005] However, the current structural design of these types of lamps allows a beam angle of no less than 24°, making it impossible to generate a narrow beam angle.

[0006] Therefore, to improve the structural design and application of the product, the inventors developed a new configuration for the AR111 and AR70 lamps that enables a beam angle between 6° and 7° and features a floating deflector to minimize glare. Compared to a 24° beam, a 6° to 7° beam angle enables higher light concentration in a specific area.

[0007] During the study of the prior art, several documents were identified that describe solutions applied to AR type LED lamps, among which the following documents deserve attention.

[0008] EP3222901 (CMC Magnetics, 2015) describes a device comprising a light-emitting module disposed below a bowl-shaped primary reflector. An auxiliary reflector is disposed on the optical axis of the light-emitting device. The primary reflector is configured to receive a portion of the light emitted by the light-emitting device and a portion of the light reflected by the auxiliary reflector. The light reflected by the primary reflector is emitted through an opening and corresponds to at least 80% of the total light output emitted through the opening.

[0009] CN205173998 (Wang Jinxia, ​​2014) describes an LED lamp, in particular a vertical heat dissipation multi-faceted LED lamp, which includes a reflector, a radiator, an AR111 base and a lamp holder bracket.

[0010] EP2276973 (Light Engine, 2009) describes a reflector placed within a main housing and a top ring thermally coupled to one end of the main housing. A heat conductor is positioned facing the front of the reflector, wherein the heat conductor includes a heat pipe thermally coupled to the top ring. An LED is thermally coupled to the heat conductor, wherein the LED is positioned directly facing the front of the reflector so that light emitted by the LED is directed toward the front of the reflector.

[0011] These references in the prior art describe structural designs for AR-type LED lamps, each characterized by its own constructional features. However, none of the references discloses a structural design that can reduce the beam angle and include a floating deflector for improving glare performance.

[0012] The object of the present invention is therefore a new structural design for LED lamps of the AR111 and AR70 types, with a narrow beam angle between 6° and 7° and a floating deflector for reducing glare. Summary of the Invention

[0013] The present invention features an LED lamp with a narrow angle and a floating deflector that provides an embedded deflector positioned closer to the light source to reduce glare.

[0014] The present invention features an LED lamp with a narrow angle and a floating deflector that provides a beam angle in the range of 6° to 7°, depending on the AR lamp model.

[0015] The present invention features an LED lamp with a narrow angle and a floating deflector that provides a sleek and clean design with a continuous geometry characterized by a smooth transition between the body and the reflector. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The LED lamp with narrow angle and floating deflector, object of the present invention, comprises a body (10) made of ABS provided with a connector (11) and receiving a reflector (20) equipped with a floating deflector (30).

[0029] The reflector (20) is made of polycarbonate, has a metalized surface, is multifaceted, and is provided with a thin edge (21). When assembled, the thin edge covers the main body (10). The reflector (20) is fixed to the main body (10) by silicone.

[0030] The floating deflector (30) is made of polycarbonate, has a metalized surface, is located in the center of the reflector (20), and has a reduced length. An LED board (40) is arranged between the reflector (20) and the deflector (30).

[0031] Therefore, the light emitted by the LED board (40) is reflected by the deflector (30), which helps to reduce glare. Whenever light is reflected, glare is reduced.

[0032] The deflector (30) includes a base (31) embedded in the reflector (20) and located above the LED board (40); a translucent cone (32) that allows the light beam generated by the LED to pass through; and a top circular structure (33) that redirects the light beam toward the reflector (20). The deflector (30) is positioned closer to the LED board (40), which helps reduce glare.

[0033] The LED board (40) is characterized by COB (Chip on Board) packaging technology, which packages multiple LED chips together to form a module with uniform lighting. The LED board (40) contains 24 internal chips.

[0034] The LED lamp with narrow angle and floating deflector enables light emitted by LED (40) to be reflected by floating deflector (30) and then reflected by multifaceted reflector (20). Thus, by this structure, a beam angle between 6° and 7° can be achieved.

[0035] The claimed LED lamp thus exhibits the following key features:

[0036] Depending on the AR light model, the beam angle is between 6° and 7°;

[0037] Fluid and clean design with continuous geometric shapes providing a smooth transition between the body and reflector;

[0038] A specialized lens with an embedded deflector (30) positioned closer to the light source to reduce glare.

[0039] Figure 10 、 Figure 11 and Figure 12 The invention shows the application of the claimed structure in the AR70 lamp model, and describes in detail the structure of the reflector (20), deflector (30) and LED board (40) assembled with the main body (10). In this lamp model with a smaller diameter, the beam angle reaches 7 degrees.

[0040] Figure 7 and Figure 12 Lamp models AR70 and AR111 are shown, arranged with a driver (50) for powering the LED board (40). The driver (50) has compact dimensions to facilitate its installation and application within the lamp.

[0041] Depending on their structural configuration, LED lamps produce a beam angle of 6° to 7°. Depending on the use requirements and market application, the beam angle can also reach values ​​above or below the stated range.
