Problems solved by technology

The existing LED street lamp is mainly composed of a shell, a lampshade and an internal LED illuminant. The sealant is used between the shell and the lampshade to seal and waterproof. This kind of street lamp is not compact in structure and large in size, so it is gradually eliminated; The street lamp is composed of multiple unit lamp tubes installed on the lamp holder. The unit lamp tube is assembled on the base plate with a long glass cover. The two ports are tightly sealed with end caps, so that the LED light source and its circuit board are sealed in Inside the lamp tube, since the contact between the glass cover and the substrate and the two ends of the cover are sealed and waterproof, it makes the disassembly and maintenance of the unit lamp tube difficult, and the internal LED light source cannot be replaced, which is inconvenient to use

Embodiment 1

[0024] Such as figure 1 As shown, this embodiment provides a new sealing element, which is used for the integral sealing of long tubular objects in the length direction and at both ends, and is made of elastic material. The sealing element includes two thin The long sealing strip 101 and the left sealing end 102 and the right sealing end 103 located at both ends are integrally formed. The inner sides of the left sealing end 102 and the right sealing end 103 have cavities 104. The sealing Both ends of the bar 101 are fixedly connected to the inner end surface of the cavity 104 and located on the left and right sides of the bottom of the inner end surface of the cavity 104 .

[0025] see figure 2 A pair of square through-holes II 107 are opened in the middle of the end face of the right sealing end 103, and two through-holes I 106 are symmetrically opened on the outer side of the through-hole II 107. Similarly, on the end face of the left sealing end 102 The same two through ...

Embodiment 2

[0028] This embodiment is the application of Embodiment 1 in LED street lamp unit lamps.

[0029] see Figure 5 and Figure 6 , the unit lamp includes a sealing member 1, a profile 2, a lampshade 3, a pressure rod 9, a left end cover 6, a right end cover 7, a circuit board 4 assembled on the profile 2, and several LEDs 5 mounted on the circuit board 4 , the main body of the lampshade 3 is an arc-shaped light-transmitting glass cover, and its two sides are respectively provided with buckles 301 (such as Figure 8 ), the main body of the lamp is formed by snapping the hasp 301 on the profile 2 and the two ends are sealed with the left end cover 6 and the right end cover 7 .

[0030] Such as Figure 11 As shown, the profile 2 includes a bottom edge 201 arranged horizontally, a first side edge 202 and a second side edge 203 are vertically arranged on both wings of the bottom edge 201, and the second side edge 203 is provided with an accommodating line The slot 204 of the board...

Abstract

The invention discloses a sealing element having function of overall sealing in a length direction and at two ends in a long tube-shaped light fitting, and a unit body light fitting comprising the sealing element. The sealing element comprises at least two sealing strips (101) positioned at a middle part and a left sealing end (102) and a right sealing end (103) positioned at the two ends, wherein the inner sides of the left sealing end (102) and the right sealing end (103) are provided with a cavity (104) respectively; two ends of the sealing strips (101) are fixedly connected with the innerend faces of the cavities (104); the inner end faces of the cavities (104) are provided with annular grooves (105); and the annular grooves (105) are matched with the shape of an end cross section ofa sealed tubular object. In the unit body light fitting of the invention, the sealing element is matched with a special structure of a section material and is matched with a left end cover and a right end cover to achieve the overall seal of the unit body light fitting and also facilitate the disassembly and the replacement of an internal circuit board and an LED light source, and the water resistance is good.

Description

technical field [0001] The present invention relates to a sealing element, more specifically, a sealing element that acts as an integral seal in the length direction and both ends of a long tubular lamp; in addition, the present invention also relates to a unitary lamp comprising the sealing element . Background technique [0002] With the mature development of LED technology, LED street lights have gradually replaced traditional street lights. Compared with traditional street lights, LED street lights not only have the advantages of long life and good chromaticity, but more importantly, they have a significant effect in energy saving. The existing LED street lamp is mainly composed of a shell, a lampshade and an internal LED illuminant. The sealant is used between the shell and the lampshade to seal and waterproof. This kind of street lamp is not compact in structure and large in size, so it is gradually eliminated; The street lamp is composed of multiple unit lamp tubes i...
