AI Technical Summary

Problems solved by technology

During the use of sealed lamps, due to the heat generated by the internal light source during operation, there is a temperature difference between the inside and outside of the lamp, which in turn causes the internal and external air pressure to be inconsistent, and easy to suck back, resulting in seal failure

Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative pur...

Abstract

The invention discloses a sealed lamp. The sealed lamp comprises a rear shell, a transparent piece, a sealing membrane and a spring, wherein a first opening end of the rear shell is connected with a second opening end of the transparent piece, so that a containing space is defined by the transparent piece and the rear shell in a surrounding manner; the sealing membrane is made of an elastic material and is slice-shaped, the sealing membrane comprises bent wrinkle parts and sealing parts positioned at the periphery of the wrinkle parts, the sealing parts are clamped between the first opening end and the second opening end, the connected positions of the first opening end and the second opening end are sealed by the sealing parts, the containing space is divided into an inner cavity close to the transparent piece and an outer cavity close to the rear shell by the sealing membrane, and the outer cavity is communicated with outside; one end of the spring is propped against a first closed end of the rear shell, the other end of the spring is propped against the wrinkle parts, and the spring provides elastic force to support the sealing membrane. According to the sealed lamp, through concave and convex parts of the sealing membrane, pressure between the inside of the sealed lamp and the external environment keeps balance, so that the sealing effect of the sealing membrane can be kept, and the service life of the sealed lamp is prolonged.

Description

Technical field [0001] The invention relates to lighting technology, in particular to a sealed lamp. Background technique [0002] In the lighting fixtures used in certain fields or industries, due to the particularity of the use occasions, there are also some special sealing requirements for the lamps. For example, sealed lamps with explosion-proof and shock-proof functions are generally used in flammable and explosive occasions. If there is a problem with the sealing of the sealed luminaire, it will not only cause damage to the luminaire, but also cause the surrounding combustible gas to explode, leading to accidents, so people have extremely high requirements on the sealing of the luminaire. [0003] Traditional sealed lamps are generally simply sealed by a sealing ring. During the use of the sealed lamp, the internal light source heats up during operation, resulting in a temperature difference between the inside and the outside of the lamp, which in turn causes the internal an...
