Temperature-controllable projection lamp core ageing device and application method thereof

Abstract

The invention discloses a temperature-controllable projection lamp core ageing device and an application method thereof. The device comprises a base, a bottom plate, a lighting box, a lighting electrode upright post, a lamp core, a compaction part, a cover, a lifting connecting plate, an air cylinder, a temperature test device, a driver, an electrical control device, an air pipe, an air pipe connecting cylinder, an exhaust fan and an air valve; and when a projection lamp core is aged, at a lighting station of the closed lighting box, the environmental temperature of the lamp core is controlled through controlling the volume of air flow. In the invention, the air valve is utilized as an air inlet, the exhaust fan is utilized as an air flow power source, and the air valve is used for controlling the size of the air inlet so as to control the air volume, thereby realizing the control on the temperature. The device provided by the invention has the advantages of simple application method, low cost, easiness for realization of automatic production, high efficiency, good consistency, good thermoregulation precision and the like.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a temperature-controllable projection lamp aging device and a use method thereof. Background technique [0002] The projector bulb is one of the important components of the projector and one of the most important consumables of the projector, which is closely related to the overall picture performance of the projector. The quality of the projection bulb basically depends on the quality of the lamp cup, the quality of the wick and the quality of the assembly process. The wick is the core of the projection bulb, and its quality is even more important. [0003] The projection wick aging device is a necessary equipment for the production of projection bulbs. As the last link in the wick production process, the aging test is carried out on the wick, and the exposed wicks with hidden dangers are screened out in time to ensure product quality. [0004] Through production and testing, it is f...

Problems solved by technology

[0005] However, the testing of the mature equipment of some projection companies found that the temperature difference between different stations is relatively large, and some even differ by more than 100 degrees, resulting in poor consistency of the experienced wicks.

[0006] However, according to the found literature, the domestic projection industry is still relatively lacking in the research and implementation of temperature control when the projection wick is mature.
