Description

Waterproof stage lamp with defogging cooling mechanism

Technical Field

The utility model relates to the field of stage lamps, in particular to a waterproof stage lamp with a defogging and radiating mechanism.

Background

Along with the rapid development of modern travel, the stage lamps are wider and wider in application range, are not only applied to indoor performances, but also widely applied to outdoor live-action performances, theme parks, urban brightening projects, landscape lighting, outdoor cultural activities and the like. When the stage lamp is applied to the outdoor or relatively humid places, the stage lamp is required to have waterproof performance, otherwise, water vapor or water drops enter the lamp, so that internal mechanical or electrical elements are easily damaged, the service life is influenced, and the stage lamp is used outdoors.

The main structure of waterproof stage lamp includes base, U type support and three majority of lamp holder, and the base is mainly responsible for power supply and main part control, and the rotation scanning and the angle zoom of horizontal, vertical position are mainly realized to the U type frame, and the lamp holder is mainly responsible for the change of various light efficiency functions.

At present, when the waterproof stage lamp is used in outdoor and outdoor occasions, the inside of the lamp cap can be influenced by the temperature difference between the inside and the outside, vaporization of various lubricating grease in the lamp body and the like, and water drops and vaporous greasy dirt are easily condensed on a lens at the front end of the lamp cap or other optical glass, or vaporous halation is formed, so that the light efficiency is seriously influenced. Aiming at the adverse phenomenon, two processing methods exist for the waterproof stage lamp at present: (1) The lamp is made into a full-sealed structure, and oil and mist are removed by a lamp internal circulation filtering method, the method is very effective in a short period, but because the lamp is in a full-sealed state, oil vapor and water vapor can only circulate in a sealed space inside the lamp all the time and cannot be discharged out of the lamp, and cannot be completely removed, so that the light efficiency can be influenced after long-term use; in addition, because the lamp is in an internal circulation state, heat dissipation inside and outside the lamp can only be completed through heat pipes or fins or heat conduction, and poor heat dissipation is easy to cause for a high-power lamp. (2) A heat dissipation air inlet and a heat dissipation air outlet are formed in the lamp cap or the U-shaped support, simple waterproof treatment is performed, and the effect of removing oil mist or water mist is achieved through internal and external circulation of the lamp. The method has good effect in sunny or relatively dry environment, but in rainy or humid environment, the air inlet of the lamp is accompanied by the entry of external moisture and humidity, which is easy to cause adverse effect and damage the inside of the lamp.
