Abstract

The utility model discloses a light emitting diode (LED) illumination lamp with a sealing structure. The LED illumination lamp comprises a light-transmitting cover (1), a lamp cup (2), LED lamp beads (3), a sponge glue strip (4), a printed circuit board (PCB), a radiator (6) and the like; the light-transmitting cover (1), the lamp cup (2), the sponge glue strip (4) and the radiator (6) are connected to form a closed cavity; the side wall of the lamp cup (2) is provided with expansion holes (7); an air bag (8) which is made of a flexible film seals the expansion holes (7); the LED illumination lamp with the structure has the sealing structure, and can adapt to a wet working environment, so the service life of the lamp is prolonged; the air bag which is made of the flexible film can effectively remove the air pressure changer which is caused by expansion and contraction; and the LED illumination lamp is high in stability, simple in structure, and low in cost.

Description

LED illuminating lamp with hermetically-sealed construction
Technical field
The utility model relates to the LED field of light fittings, relates in particular to a kind of LED illuminating lamp with hermetically-sealed construction that is operated in wet environment.
Background technology
Led light source is through semicentennial developing rapidly, led light source, the bright led light source of particularly high-power height;, volume little, long service life high with its light efficiency, and many-sided advantage such as environmental protection and energy saving have obtained application more and more widely in the lighting source field; And still in continuing to develop rapidly, the LED illuminating lamp in use can produce great amount of heat, and the gas that causes lamp interior expands and to the light fixture flows outside; Thereby cause the air pressure of lamp interior to reduce, and when extinguishing or run into the cold airflow impact, the light fixture outside is prior to its inner cooling; Cause the air pressure of lamp interior to be lower than outside air pressure again, air outside is sucked lamp interior, through so long-term accumulation and reciprocal; Airborne steam will have a strong impact on the stability of LED illuminating lamp, especially when being operated in wet environment, more need carry out encapsulation process to light fixture; Existing LED illuminating lamp adopts solid structure that light fixture is sealed; The gas and the outside of lamp interior are isolated fully, but this can cause the light fixture inner and outer air pressure uneven because of expanding with heat and contract with cold, and causes encapsulating structure more fragile.
The utility model content
The purpose of the utility model is to provide a kind of LED illuminating lamp with hermetically-sealed construction that can adapt to moist working environment, resists the infringement of steam through sealing.
The purpose of the utility model is achieved in that the LED illuminating lamp with hermetically-sealed construction; Comprise assemblies such as diffuser, Lamp cup, LED lamp pearl, sponge adhesive tape, pcb board, radiator, diffuser, Lamp cup, sponge adhesive tape and radiator are installed and are connected into airtight cavity, and radiator adopts aluminium alloy extruded one-tenth slab construction; The outside is provided with radiating fin; The bead weld of LED lamp is connected on the radiator inside top pcb board, and Lamp cup adopts the minute surface aluminium sheet of high reflectance to process, and is fastened on the radiator through connector; The sponge adhesive tape is arranged between Lamp cup and the radiator; Adopt the transparent glass of high transmission rate or the diffuser that prism PMMA processes to be installed in the Lamp cup bottom, be formed with inflation port on the sidewall of Lamp cup, the air bag that adopts flexible membrane to process closes inflation port.
Further scheme is, said inflation port is a bar hole, and two inflation port are symmetricly set on the Lamp cup root.
Adopt the LED illuminating lamp of this structure, have hermetically-sealed construction, can adapt to moist working environment; Prolong the service life of light fixture; And adopt flexible membrane to process airbag structure, and can separate the air pressure change that the heat expansion shrinkage causes by validation, stability is better and simple in structure, with low cost.
Below in conjunction with accompanying drawing and embodiment the utility model is further set forth, the protection domain of the utility model includes but are not limited to accompanying drawing and the disclosed content of embodiment.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
As shown in Figure 1, this LED illuminating lamp includes assemblies such as diffuser 1, Lamp cup 2, LED lamp pearl 3, sponge adhesive tape 4, pcb board 5, radiator 6, and diffuser 1, Lamp cup 2, sponge adhesive tape 4, pcb board 5 assemblings connect into airtight cavity; 6 one-tenth tabulars of radiator, the outside is provided with radiating fin, and LED lamp pearl 3 is welded on the pcb board; And being fixed on radiator 6 bottom surfaces, the Lamp cup 2 that the minute surface aluminium sheet of employing high reflectance is processed is fastened on the radiator 6; And sponge adhesive tape 4 is arranged between Lamp cup 2 and the radiator 6, realize sealing, diffuser 1 airtight Lamp cup 2 lower surfaces that are sealed on of adopting the transparent glass of high transmission rate to process; Be formed with two bar shaped inflation port 7 on the sidewall of Lamp cup 2; Be positioned at the root of Lamp cup 2 near radiator, the air bag 8 that adopts flexible membrane to process closes inflation port 7, when illuminating lamp is worked; Temperature raises, and light fixture internal gas pressure rising air bag 8 is in relaxed state.
