Problems solved by technology

[0003] In order to solve the problem that outdoor lighting fixtures are easily damaged by rainwater, in the prior art, the lighting fixtures are generally sealed and packaged, that is, resin glue is poured into both sides of the LED lamp bead and the circuit board (PCB), so that the rainwater cannot directly contact with it. The LED lamp beads and the circuit board are in direct contact to achieve waterproof effect
However, due to the general waterproof effect, once the rainwater enters, the circuit board will be damaged and the entire LED lamp will be scrapped

Embodiment 1

[0049] Embodiment one, with reference to Figure 1 to Figure 4 :

[0050] A lamp provided in this embodiment includes a lampshade 1 , a lamp cap 2 connected to the lampshade 1 , and electronic components and light source devices located in the lampshade 1 and electrically connected to each other. Wherein, the lampshade 1 is a light-transmitting plastic lampshade, and the lampshade 1 can be integrally blow-molded, which helps to improve the anti-drop performance of the lamp and avoids the use of open flames in the production process.

[0051] The lampshade 1 includes a cover body 11 and an installation part 12 integrally connected to the cover body 11 , and the installation part 12 is inserted into the lamp cap 2 . The outer surface of the cover body 11 is provided with a plurality of evenly arranged lampshade grooves 111 , so that the light will be refracted when passing through the cover body 11 , and a more brilliant lighting effect can be obtained. The shape of the cover ...

Embodiment 2

[0059] Embodiment two: refer to figure 1 and Figure 5

[0060] The difference between the present embodiment and the first embodiment is that a first limiting protrusion 36 extending from the periphery of the first through hole 311 in a direction away from the PCB board 5 prevents the displacement of the second electronic component 42 , and / or the second limiting protrusion (not shown in the figure) extends from the periphery of the second through hole 312 in a direction away from the PCB board 5 . It is worth noting that the setting of the first limiting protrusion 36 is to limit the circumferential displacement of the second electronic component 42 during assembly, and the specific first limiting protrusion 36 is a plurality of protrusions with a certain degree of elasticity. Formed, when the second electronic component 42 passes through the first through hole 311 and passes through the first limiting protrusion 36 , the first limiting protrusion 36 undergoes elastic def...

Embodiment 3

[0061] Embodiment three: refer to figure 1 , Image 6 and Figure 7 :

[0062] The difference between this embodiment and the first embodiment is that the outer surface of the lamp post 3 is provided with an annular groove 33 along the peripheral direction, and a sealing ring 8 is arranged inside the annular groove 33 . The waterproof effect of the LED 6 arranged in the lampshade 1 is good, and the sealing performance between the lamp post 3 and the lampshade 1 is further improved.

Abstract

The invention discloses a lamp and a production process thereof. The lamp comprises a lampshade, a lamp holder, a light source device and an electronic component, the light source device and the electronic component are electrically connected with each other, the lampshade comprises a lampshade body and an installation part, the installation part is inserted into the lamp holder in a penetrating mode, a lamp post is arranged in the installation part in an interference fit mode, a through hole allowing the electronic component or a wire to penetrate through is formed in the lamp post, and the through hole penetrates from one side of the lamp post to the other side of the lamp post. According to the lamp, the electronic component is arranged in the through hole of the lamp post in a penetrating mode, the electronic component is effectively prevented from moving, and therefore the loss rate of the lamp is reduced; by means of interference fit between the installation part and the lamp post, the lamp post is plugged into the installation part of the lampshade in a pressing mode, good sealing performance is formed between the lamp post and the lampshade, the waterproof effect for the light source device and the electronic component arranged in the lampshade is good, and the waterproof grade of the lamp is effectively improved; and the production process is simple, and the cost is lower.

Description

technical field [0001] The invention relates to the lighting field, in particular to a lamp and a production process thereof. Background technique [0002] With the development of economy and society and the improvement of lighting equipment technology, lamps and lanterns have been more and more widely used in people's daily life, and also more and more used in various outdoor occasions, such as outdoor landscape lighting, lighting Lighting and large-scale building lighting, etc. [0003] In order to solve the problem that outdoor lighting fixtures are easily damaged by rainwater, in the prior art, the lighting fixtures are generally sealed and packaged, that is, resin glue is poured into both sides of the LED lamp bead and the circuit board (PCB), so that the rainwater cannot directly contact with it. The LED lamp beads and the circuit board are in direct contact to achieve waterproof effect. However, due to the general waterproof effect, once rainwater enters, the circui...
