Description

Novel LED lamp with two-section telescopic lamp cup design

Technical Field

The utility model relates to the field of LED light sources, in particular to an improved novel LED lamp with a double-section telescopic lamp cup design.

Background

LED lamps, such as LED spot lamps, are widely used due to their advantages of power saving, safety, high brightness, long life, etc. Among them, the MR16 type LED spotlight is a popular lamp type, and has been widely used worldwide, especially in outdoor courtyard landscape lighting, and the MR16 spotlight has been replaced by LEDs substantially entirely.

The current MR16 spot lamp is based on white light and has sufficient brightness to replace halogen lamps. In outdoor courtyard landscape lighting, a colorful color-changing MR16 is strongly required, preferably an MR16 in which both the color light and the white light can be changed, and the brightness of the color light is enough (the brightness of a single color is up to 6 w). At present, the MR16 with single color R/G/B color change exists in the market, but the power is only about 2w, the brightness is too low, the mixing effect of white light and color light is poor, and color separation often occurs. In order to improve the performance, some manufacturers adopt lengthening lamp cup sizes, and because the sizes exceed the standard, many LED lamps are not matched, so that the market demands are difficult to meet.

The current MR16 shot-light adopts lens + lamp cup + three-section type that connects mostly, and the light source is packed into by the anterior segment, and the power is packed into from the joint end, and this benefit is convenient for light source, power can reprocess respectively, and the utilization ratio of the space in lamp cup is low, can't hold bigger size power in the defect. If an MR16 lamp with sufficient power brightness to dim RGB + white light is to be realized with a physical size that meets IEC standard or ANSI standard, a larger power supply would have to be accommodated. This presents new challenges to existing structural designs.

In view of the foregoing, there is a great need in the art for an improved LED spotlight as described above that overcomes or ameliorates the above-described technical shortcomings and achieves corresponding and further advantages.

The information included in this background section of the specification of the present utility model, including any references cited herein and any descriptions or discussions thereof, is included solely for the purpose of technical reference and is not to be construed as a subject matter that would limit the scope of the present utility model.

The present utility model will be described in more detail below with reference to specific embodiments thereof.

Fig. 1 is a schematic front projection view showing the side of a novel LED lamp having a two-segment telescopic (also referred to as a double nested) lamp cup design according to a first embodiment of the present utility model. Fig. 2 is an exploded schematic view of the novel LED lamp shown in fig. 1, schematically illustrating the general construction and assembly of the novel LED lamp. Fig. 3 is a schematic longitudinal sectional view of the novel LED lamp shown in fig. 1, after assembly, along its longitudinal centerline, schematically showing a schematic construction and partial details of the assembly of the novel LED lamp.

As shown in fig. 1-3, a novel LED lamp having a dual segment telescopic lamp cup design is disclosed, comprising a power module 20 and a light source module 10, the power module 2020 and the light source module 10 being, for example, detachably or releasably assembled together.

The light source module 10 includes a first generally cylindrical lamp cup section 16, an LED lamp panel 15 mounted within the first cylindrical lamp cup section 16, and an optical lens module 12. The LED lamp panel 15 mainly includes a heat dissipation substrate, a plurality of LEDs preferably packaged on the heat dissipation substrate by COB (Chip on Board), and optionally a plurality of pads. The number, power and color of the LEDs, e.g., colored LEDs and white LEDs, may vary depending on the customer's requirements and design requirements. The heat-dissipating substrate is preferably a substrate that conducts heat well, such as a ceramic substrate and a metal substrate (e.g., an aluminum substrate), in order to provide good heat dissipation properties to the LED lamp. COB packages are preferred for fully utilizing the limited cup volume of LED lamps, good heat dissipation design, and increased optical power. According to an example, in the LED lamp of the present utility model, the LEDs may be single color LEDs, multi-color LEDs, white LEDs, and the light power (brightness) and color, color temperature of the LEDs may be varied, for example, the color temperature of the white LEDs may be adjusted in the range of 2200K-6000K, and may be intelligently adjusted in an intelligent, wireless communication (e.g., bluetooth, as described below) manner.

In order to realize the wireless intelligent regulation function on the novel LED lamp, a Bluetooth antenna is arranged on the novel LED lamp so as to receive (and/or transmit) Bluetooth signals. To this end, according to an example, an antenna bracket 13 may be mounted in the first cylindrical lamp cup section 16 to facilitate assembly of the bluetooth antenna. As shown in fig. 2-3, the antenna support 13 may be integrally formed of, for example, a circular arc segment with supporting legs formed by injection molding plastic, where the supporting legs of the antenna support 13 are supported on the LED lamp panel 15, and the circular arc segment of the antenna support 13 is clamped between the optical lens module 12 and the LED lamp panel 15, specifically, the circular arc segment of the antenna support 13 is propped against the back surface of the optical lens module 12 and forms a clamping groove 18 with the optical lens module 12 (as shown in fig. 3), so that the bluetooth antenna is reliably arranged (e.g., clamped) between the antenna support 13 and the clamping groove 18 formed between the optical lens module 12 and is spaced apart from the first cylindrical lamp cup segment 16 of metal and the LED lamp panel 15 (as shown in fig. 3) by a distance from the lamp cup so as to minimize or eliminate possible metal shielding interference.

According to an example, the maximum light power of the new LED lamp is at least 6 watts, and both the light power and the light color of the new LED lamp are adjustable. For example, the new LED lamp can be operated at full power 6W when operating at any of its light colors, a high light power being desirable and more cost-effective for the user. In contrast, many similar LED lamp products on the market are not enough in power when emitting monochromatic light, even only 30% of the power, namely about 2W, and only near 6W when mixing white light. Therefore, the novel LED lamp provided by the utility model not only can reduce development difficulty, but also can reduce production and use costs.

The power module 20 generally includes a unitary cup-shaped or cup-shaped second cup-shaped cup section 21, an LED drive power supply 17 mounted within the second cup-shaped cup section 21, and an external power connector 22. The second cup-shaped lamp cup section 21 has an open end, i.e. the end connected to the first cylindrical lamp cup section 16; and an opposite convergent end (or "convergent end"), i.e., the end in which the external power connector 22 is mounted, such as by snap-in insertion. As shown in fig. 1, the first cylindrical cup section 16 is removably telescopically assembled to the open end of the second cup section 21 and the outer power connector 22 is connected to the converging end, resulting in an LED lamp having a double nested or telescopic cup configuration as shown in fig. 1 and 3 after assembly. To this end, according to one example, the outer diameter of the first cylindrical lamp cup section 16 is designed to be less than or equal to the inner diameter of the open end of the second cup-shaped lamp cup section 21, and the first cylindrical lamp cup section 16 is detachably assembled in the open end such that the first cylindrical lamp cup section 16 is nearly flush with the open end in the axial direction or slightly exposes the open end (shown in fig. 3).

As shown in fig. 2-3, one example configuration of the removable telescopic assembly is to design the external screw thread 16 in the assembly section of the first cylindrical lamp cup section 16 and 211 in the corresponding assembly location of the second cup lamp cup section 21, whereby the first cylindrical lamp cup section 16 and the second cup lamp cup section 21 are removably screwed (screwed) telescopically assembled together and are conveniently counter-screwed.

As shown in fig. 2-3, according to an example, the new LED lamp may further comprise an aluminum press ring 11, the aluminum press ring 11 being a tight fit (interference fit) in the circumferential direction between the first cylindrical lamp cup section 16 located radially outward and the optical lens module 12 located radially inward when the new LED lamp is assembled, so as to press the optical lens module 12 against and fix it on the first cylindrical lamp cup section 16. The assembly structure and the assembly mode make full use of the aluminum compression ring which is easy to deform and assemble, and the aluminum compression ring has good heat dissipation, can be convenient and fast, has low cost and is easy to disassemble and maintain, the structure of the LED lamp is simplified, and the most important is that the structural space of the LED lamp is greatly saved. Thus, the lenses of the optical lens module 12, whether concave, convex or planar, can be easily removed and replaced to meet customer and application requirements without having to re-customize the entire LED lamp, thereby greatly saving the cost of producing, designing, installing and maintaining the LED lamp, which is of great benefit to both customers and manufacturers.

To ensure good heat dissipation and lifetime of the LED lamp of the present utility model, according to an example, the first cylindrical lamp cup section 16 and the second cup-shaped lamp cup section 21 may each be formed of a thermally conductive material, e.g. a metallic material such as aluminum, integrally molded. Also, inner heat radiating fins 213 may be provided on the inner peripheral wall of the second cup-shaped lamp cup section 21, and outer heat radiating fins 214 may be provided on the outer peripheral wall thereof so as to promote heat radiation. The inner heat sink fins 213 not only facilitate heat dissipation, but also increase the heat dissipation area, but also facilitate more or less convective heat dissipation of air, due to the axially extending, radially inwardly projecting ribs/ridges or fin configuration of the inner heat sink fins 213 themselves, further creating a radial space between the second cup-shaped lamp cup section 21 and the optical lens module 12 that extends axially for a length.

According to an example, the outer power connector 22 is preferably integrally injection molded with the plastic bracket 220 from two power pins (or pins, etc.) 222 to preserve/increase the power pin metal portion as much as possible, and to increase the heat capacity and heat dissipation area to ensure adequate heat dissipation and durable stability. The power pin 222 has one end exposed to the external power connector 22 and the other end electrically connectable to the LED driving power source 17 through an internal wire (not shown). The plastic bracket 220 is provided with two wedge-shaped reverse buckling parts 221 at the other end opposite to the exposed end of the power pin 222. In this way, during assembly, the external power connector 22 can be inserted from the converging end, so that the wedge-shaped back-off 221 snaps against one step 210 of the second cup-shaped lamp cup segment 21, while the step structure (shown in fig. 3) of the plastic bracket 220 snaps against the other stop step 212 of the second cup-shaped lamp cup segment 21, thereby snapping the external power connector 22 onto the converging end of the second cup-shaped lamp cup segment 21. In the process of disassembly, other internal structures of the second cup-shaped lamp cup section 21 can be disassembled, and the wedge-shaped back-off part 221 is pinched from top to bottom from the second cup-shaped lamp cup section 21 shown in fig. 3 to be separated from the buckle, and is pushed out from the convergence end from top to bottom, so that the disassembly can be completed.

According to an example, the new LED lamp is mainly designed as an MR16 type LED lamp, such as an LED spotlight, mainly used for outdoor courtyard landscape lighting. Thus, it is preferred that the new LED lamp is designed such that its total length (or total height of the lamp) and the maximum outer diameter of the lamp cup (i.e. the maximum outer diameter of the second cup-shaped lamp cup section 21 shown in fig. 2-3) meet the requirements of the IEC60630-4010-2 standard in order to meet customer and market requirements. The overall length of the novel LED lamp and the maximum outer diameter of the lamp cup of another embodiment of the present utility model can also be designed to follow the american national standard ANSI-C78.24-2001 to meet and facilitate the demands of the united states market and users.

As described above, the novel LED lamp can wirelessly regulate and control the light power/brightness in a Bluetooth communication mode, including regulating and controlling the light power/brightness of the LED lamp through an MCU or through a resistor, and the like. The regulation and control of the light power/brightness of the LED lamp by the MCU is a preferable scheme, because different electric signals can be output by using a preset control program in the MCU to control the output current, thereby greatly reducing the design volume of the circuit board and the LED lamp, which is very ideal and valuable for the LED lamp meeting the requirements of relevant foreign standards.

The novel LED lamp is suitable for being used as various LED spot lamps, such as outdoor LED spot lamps, especially high-power outdoor LED spot lamps, courtyard LED spot lamps, landscape lighting LED spot lamps and the like.

The foregoing description of several embodiments of the utility model has been presented for the purposes of illustration. It is not intended to be exhaustive or to limit the utility model to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The scope of the utility model and all equivalents are intended to be defined by the appended claims.
