When the lenses need to be replaced, pressing the sealing member, take out the original lens and then install into a new lens. The LED lamp is convenient to replace lens.

Description

LED lamp with interchangeable lens

The invention relates to an LED lamp, in particular to an LED lamp with a replaceable lens.

The LED light line is soft and penetrating. Compared with traditional incandescent lamps, it has the characteristics of energy saving and long service life. It is gradually replacing incandescent lamps into people's lives. Due to long-term use of the LED lamp, the lens may become blurred and the light transmittance is not high, or the lens needs to be replaced. Most of the lenses of LED lamps are connected to the upper and lower casings of the LED lamp by screws to fix the lens between the upper and lower casings. When the lens needs to be replaced, unscrew the screw to separate the upper and lower casings and take out the lens to replace the new lens. The above-mentioned LED lamp replacement lens process is complicated, which brings inconvenience to the user.

In view of this, it is necessary to provide an LED lamp that can be easily replaced with a lens.

An LED lamp with an interchangeable lens, comprising an upper casing, a lower casing fixedly connected to the upper casing, a circuit board and a lens, wherein the circuit board is electrically connected with a plurality of LEDs and placed in the upper casing and the Between the lower casings, the lower casing is formed with a through hole for emitting light emitted by the LED, and the lower casing is adjacent to the through hole to form a sliding passage with one end open, and the lens is slidably mounted on In the slide, the lower casing is movably fixed at the slide opening with a closing member for closing the slide opening.

After the lens of the LED lamp is placed in the lower casing, the lens is blocked by the closing member to prevent the lens from sliding out of the lower casing. When the lens needs to be replaced, pressing the closing member to take out the original lens and re-insert the new lens. It has the advantages of convenience and speed.

1 is a perspective view of an LED lamp in an embodiment.

2 is an exploded view of the LED lamp of FIG. 1.

3 is an exploded view of another perspective of the LED lamp of FIG. 1.

Figure 4 is a cross-sectional view of Figure 1 with the upper housing removed.

The present invention will be described in detail below with reference to the embodiments and the accompanying drawings.

Referring to FIG. 1, the LED lamp 100 includes an upper casing 10, a lower casing 20 fixedly coupled to the upper casing 10, a closure member 40 movably fixed to the lower casing 20, and a slidably inserted lower casing 20 The lens 50 inside. The closure 40 is used to block the lens 50 to prevent the lens from slipping out of the lower housing 20.

Referring to FIG. 2 and FIG. 3 simultaneously, the LED lamp 100 further includes a circuit board 30 disposed between the upper casing 10 and the lower casing 20, and the circuit board 30 is electrically connected with a plurality of LEDs 32. The circuit board 30 is electrically coupled to a power source to provide power to the LEDs to illuminate.

The lower casing 20 includes a body 202 and two side walls 206 that are oppositely protruded from an edge of the body 202 in the longitudinal direction. A rectangular through hole 204 is formed between the two side walls 206 of the body 202 for the light emitted by the LED 32 to be emitted. The top end of the side wall 206 is bent toward the through hole 204 to form a slide 208 for the lens 50 to slide in. The slide 208 is open at one end.

An inclined receiving groove 210 is disposed on the body 202 adjacent to the opening of the slide 208 for receiving the closure 40.

Referring to FIG. 4 at the same time, the closure member 40 includes a pressing block 42 and an elastic member 44 fixed to the pressing block 42. The pressing block 42 includes a rotating shaft 43 rotatably fixed to the lower casing 20 and a slanted rotating body 45 radially connected to the rotating shaft 43. In this embodiment, two positioning blocks 212 are convexly disposed on the body 202. The block blocks 212 are respectively disposed on both sides of the accommodating groove 210, and an opening 214 is formed thereon to be inserted into the rotating shaft 43 to rotate the rotating shaft 43 in the opening 214. The rotating body 45 is received in the accommodating groove 210. After the lens 50 slides into the sliding path 208, one end of the rotating body 45 closes the sliding path 208 and abuts the lens 50 under the action of the elastic member 44, preventing the lens 50 from sliding out of the sliding path. 208, the other end is resisted by the accommodating groove 210 away from the edge 205 of the slide 208, and the blocking member 40 is dropped out of the accommodating groove 210. In this embodiment, the shape of the rotating body 45 is matched with the receiving groove 210 to close the receiving groove 210 and the sliding channel 208 to make the LED lamp 100 more beautiful.

The elastic member 44 includes two free ends 46, a spiral portion 48 formed by winding from the two free ends 46, and a connecting portion 49 connecting the two spiral portions 48. The spiral portion 48 is sleeved on the rotating shaft 43, the free end 46 is abutted on the rotating body 45, and the connecting portion 49 is placed on the body 202 to provide elastic force to close the slide 208 of the rotating body 45 to prevent the lens 50 in the sliding path 208. The body 202 is slid out during the flipping of the LED lamp 100. In this embodiment, the swivel 45 is further provided with a card slot 47. The free end 46 includes a hook portion 41 hooked in the slot 47 so that the free end 46 is in close contact with the pressing block 42.

After the lens 50 of the LED lamp 100 is placed in the slide 208, the closure 40 closes the slide 208 due to the elastic force of the elastic member 44, and the lens 50 does not slide out of the lower casing 20. When the lens 50 needs to be replaced, the rotating body 45 is pressed to rotate to the inner side of the lower casing 20 to disengage the rotating body 45 from the sliding path 208, and the lens 50 can be taken out and put into a new lens, which is convenient and quick. .

In addition, those skilled in the art can make other changes in the spirit of the present invention. Of course, the changes made in accordance with the spirit of the present invention should be included in the scope of the present invention.
