Embodiment Construction

[0044] The present invention is further described in conjunction with the following examples.

[0045] A kind of LED projection lamp of this embodiment, such as Figure 1 to Figure 4 , Figure 7As shown, it includes a strip-shaped lamp cavity 1, lamp beads 2 and a light-transmitting plate 3. The strip-shaped lamp cavity 1 includes a cavity bottom 11 and two cavity side walls 12 with the same structure and symmetrically arranged. The lamp beads 2 Placed in the strip-shaped lamp chamber 1, in this embodiment, it also includes two glands 5 with the same structure and symmetrically arranged, and two identically structured and symmetrically arranged caps for waterproofing and balancing the pressure inside and outside the strip-shaped lamp chamber. Breathing waterproof strip 4, the breathing waterproof strip 4 is a breathing waterproof strip 4 with elasticity, one said breathing waterproof strip 4 is close to the inner side of a cavity side wall 12 and cavity bottom 11 of the strip...

Abstract

The invention provides an LED project lamp, and relates to the technical field of LED lamps. The LED project lamp structurally comprises a strip-shaped lamp cavity, a lamp bead and a light transmitting plate. The strip-shaped cavity comprises a cavity bottom and two cavity lateral walls, two breathable waterproof strips are arranged, the breathable waterproof strips are tightly matched with the inner sides of the cavity lateral walls of the strip-shaped lamp cavity, the space of the strip-shaped lamp cavity can be reduced, steam in the strip-shaped lamp cavity can be reduced, therefore, the breathing effect is reduced, and balance of internal pressure of the strip-shaped lamp cavity and external pressure of the strip-shaped lamp cavity can be achieved more effectively due to the fact that the breathing effect of the breathable waterproof strips themselves is good. By using the elastic breathable waterproof strips, one breathable waterproof strip is tightly attached to the inner side of one cavity lateral wall of the strip-shaped lamp cavity and the cavity bottom of the strip-shaped lamp cavity, the other breathable waterproof strip is covered by a gland, the gland enables the corresponding breathable waterproof strip to make tight contact with the cavity bottom of the strip-shaped lamp cavity and the inner side of the cavity lateral wall of the strip-shape lamp cavity at the same time, and therefore a good waterproof effect can be achieved; due to the fact that breathable waterproof strips can have two purposes, the LED project lamp is made to be compact in structure, low in cost and easy to assemble.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED flood lamp. Background technique [0002] LED floodlights, commonly known as LED wall washers, as the name suggests, let the light wash the wall like water, and are mainly used for architectural decoration lighting, and are also used to outline the outline of large buildings. Since LED has the characteristics of energy saving, high luminous efficiency, rich colors, and long life, the wall washer of other light sources has been gradually replaced by LED wall washer since 2013. [0003] Since LED floodlights are outdoor lighting fixtures, temperature changes, dust, dirt and moisture will affect the electronic components of outdoor lighting fixtures. For example, rainfall may cause the lamp housing to cool rapidly, thereby forming a vacuum of 200mbar (3psi) or even greater in the housing, and rain or water vapor (or water vapor) penetrating into the lamp housing will serio...
