Abstract

An LED lamp capable of emitting light toward the periphery and rear is provided. An LED unit is installed on a main body. The lamp shade 30 is installed so as to cover the outside of the LED unit 20. The reflective component 40 is installed to stand upright in the lamp shade 30. A reflective slope 44 is formed around the reflective component 40 and gradually contracts and extends toward the LED unit 20. When the LED unit 20 starts the light emission operation, the reflecting slope 44 reflects a part of the light beam to the rear of the lamp shade 30, whereby the LED lamp can emit the emitted light at a wide angle, and the illumination angle can be increased. In addition to being able to enlarge and compensate for the lack of luminance at the rear, a uniform light emission effect can be achieved. [Selection] Figure 5

Description

  The present invention relates to an LED lamp.

LEDs have advantages such as low operating voltage, long service life, and no mercury contamination, so they are widely used in various lighting devices, replacing traditional lighting fixtures such as light bulbs and fluorescent lamps. It is supposed to be.
As shown in FIG. 1, which is a schematic diagram of a conventional LED bulb in use, the conventional LED bulb includes a main body 1, and an LED unit 2 is installed on the main body 1.
A lamp shade 3 is placed outside the LED unit 2.
As a result, when a conventional LED bulb is energized, the LED unit 2 emits light, and the light passes through the lamp shade 3 to achieve the illumination effect.

However, as shown in FIG. 1, the light emitted from the LED is direct light, so that there is a problem that the light emission angle is small and the light source is concentrated.
Therefore, the light emitted from the LED unit 2 by energizing the conventional LED bulb is only irradiated to the front of the lamp shade 3, and the periphery and the rear of the lamp shade 3 may be relatively dark and uniform. The effect of light emission cannot be achieved.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an LED lamp that can emit light rays around and behind.

In order to solve the above problems, the present invention provides the following LED lamp.
The LED lamp includes a main body, an LED unit, a lamp shade, and a reflective component. The LED unit is installed on the main body. The lamp shade is installed so as to cover the outside of the LED unit. The reflective component is installed so as to stand upright in the lamp shade, and a reflective slope is formed around the reflective unit that gradually reduces and extends toward the LED unit.
The LED lamp of the present invention advances the light beam in the direction of the reflecting component when the LED unit starts the light emission operation. At this time, since the periphery of the reflective component forms a reflective slope, a part of the light beam is reflected by the reflective slope, and is emitted around and behind the lamp shade. Thereby, the LED lamp can emit the emitted light at a wide angle. As described above, the present invention can increase the illumination angle and compensate for the lack of luminance at the rear, and can achieve the effect of uniform light emission.

  The LED lamp of the present invention can emit light to the periphery and the back by emitting the emitted light at a wide angle, thereby achieving a uniform light emitting effect.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

(First embodiment)
As shown in FIGS. 2, 3, and 4, which are a perspective view, an exploded perspective view, and a cross-sectional view of the first embodiment of the present invention, the LED lamp 100 includes a main body 10, an LED unit 20, a lamp shade 30, and a reflective component 40. Prepare. The LED lamp 100 is not disposable.

The main body 10 includes a connecting head 11 and can be connected to a lamp socket (not shown) corresponding to a standard such as E27 standard or MR16 standard.
In the present embodiment, the connecting head 11 is an E27 standard connecting head.
One end of the connecting head 11 is provided with a bearing portion 12 extending outward along the axial direction.
The bearing portion 12 is formed by fitting at least two metal cases 121 to each other.
The metal cases 121 are connected to each other by at least one connecting part 122 with a gap a formed therebetween.
In the present embodiment, the bearing portion 12 is configured by fitting two metal cases 121 together, and a connecting plate is integrally formed between the metal cases 121 to form a connecting part 122.

The LED unit 20 is installed on the main body 10.
In the present embodiment, the LED unit 20 includes a circuit board 21 that is fixedly installed on the bearing portion 12. A plurality of LEDs 22 are installed on the circuit board 21.
The LED unit 20 further includes a drive module 23.
The drive module 23 is electrically connected between the connecting head 11 of the main body 10 and the circuit board 21, thereby causing each LED 22 to emit light.

  The lamp shade 30 is provided so as to cover and cover the outside of the LED unit 20. The lamp shade 30 is formed with perforations 31 at the end facing the LED unit 20.

The reflective component 40 is installed so as to stand upright in the lamp shade 30.
One end of the reflective component 40 is defined as a fixed end 41. The fixed end 41 is gradually reduced in the direction of the lamp shade 30 and extends, and is formed in a diamond cone shape.
A lock hole 42 corresponding to the perforation 31 is formed on the end surface of the fixed end 41, and can be fixed by being screwed into the lock hole 42 through the perforation 31 by a lock component 50 such as a bolt.
In this way, the reflective component 40 is fixed to the inner wall of the lamp shade 30.
The other end of the reflective component 40 has a free end 43 and is gradually reduced and extended in the direction of the LED unit 20 to form a rhomboid cone.
A reflective slope 44 is formed around the free end 43.

As shown in FIG. 5, which is a schematic diagram of the usage state of the first embodiment of the present invention, when the user turns on the LED lamp 100, the LED 22 on the LED unit 20 starts to emit light, and the light beam is a reflective component. Advance in the direction of 40.
Since the reflective component 40 is installed in the lamp shade 30 and the reflective slope 44 is formed around the reflective component 40, at this time, a part of the light beam is reflected by the reflective slope 44, and the lamp shade 30 It is injected around and back.
In this way, the LED lamp 100 can emit the emitted light at a wide angle.

It has been confirmed by actual tests that the maximum emission angle of the conventional LED bulb is about 180 degrees, whereas the maximum emission angle of the LED lamp 100 of the present invention reaches 270 degrees.
As a result, the LED lamp 100 can expand the illumination angle, compensate for the lack of luminance at the rear, and achieve a uniform light emission effect.

Further, the fixed end 41 of the reflecting component 40 is gradually reduced in the direction of the lamp shade 30 and extended to form a rhombus cone, so that the shadow that the reflecting component 40 drops on the lamp shade 30 is greatly reduced. be able to.
This makes it difficult for the user to notice the presence of the reflective component 40.

Further, the bearing portion 12 of the main body 10 is configured by fitting at least two metal cases 121 to each other, and each metal case 121 is connected to each other by a connecting part 122 with a gap a formed therebetween. Therefore, the contact area between the bearing portion 12 and the air can be greatly increased.
Thereby, it is possible to effectively dissipate the heat generated by each LED 22, and it is possible to avoid that each LED 22 causes thermal runaway due to heat dissipation failure.

As shown in FIG. 6, which is a cross-sectional view of the second embodiment of the present invention, the difference between the LED lamp 100 of the second embodiment of the present invention and the above-described embodiment is on the reflective slope 44 of the reflective component 40. Furthermore, a reflection layer 45 such as a chrome plating layer is provided.
Thereby, the reflective capability of the reflective slope 44 can be strengthened.
At the same time, the main body 10 further has a plurality of heat radiating holes 123 formed on each connecting part 122 and the partition 13 is installed in the gap a.
Thereby, the heat dissipation capability of the bearing portion 12 can be further expanded. Therefore, more LEDs 22 can be installed in the LED unit 20, or the wattage of the LEDs 22 can be increased, and the light emitting effect can be further enhanced.
