Embodiment Construction

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being “fixed on” or “abutting against” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used her...

Abstract

An emergency lamp comprises a shell, a circuit board, a light source, a thermoelectric sensing piece and a battery. The shell is of a barrel structure, a partition is arranged in the middle of the shell and divides a cavity of the shell into a light source cavity and an electrical cavity, the circuit board is fixed on the surface, close to the light source cavity, of the partition and arranged closely to the partition, the light source is fixed on the circuit board and electrically connected with the same, the thermoelectric sensing piece is fixed on the surface, close to the electrical cavity, of the partition, arranged closely to the partition, made by a thermoelectric material and used for converting thermal energy into electric energy, the battery is fixed in the electrical cavity, electrically connected with the thermoelectric sensing piece to form a charging loop and electrically connected with the circuit board, heat generated by the light source and the circuit board is transmitted to the thermoelectric sensing piece through the partition, and the thermoelectric sensing piece after absorbing the heat generates temperature difference to convert thermal energy into electric energy to charge the battery. The emergency lamp can effectively utilize thermal energy, is energy saving and environment friendly and can obtain better heat-dissipating effect.

Description

【Technical field】 [0001] The invention relates to a special lighting fixture, in particular to an emergency lighting fixture. 【Background technique】 [0002] The traditional heat dissipation method in the lamp is to transfer the heat out through the shell contacting the heating part, the efficiency is relatively low, and the temperature is not uniform. Lamps with emergency functions charge their rechargeable batteries through external input to ensure emergency power supply after power failure. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide an emergency lamp, which can effectively utilize heat energy, save energy consumption, and enable the emergency lamp to obtain a better heat dissipation effect. [0004] An emergency lighting device comprising: [0005] The casing is a cylindrical structure, and the middle part of the casing is provided with a partition, and the partition divides the cavity of the casing into a light source c...
