Description
本發明涉及一種投影機燈泡固定結構,尤其涉及一種避免燈泡反射罩透光形成雜散光而影響光學性能的投影機燈泡固定結構。The invention relates to a projector lamp fixing structure, in particular to a projector lamp fixing structure which avoids light transmission of a bulb reflector to form stray light and affects optical performance.
投影機產品的結構中光學引擎(Optical Engine) 是一個重要的關鍵元件,其包括有一光源燈具以及一光學元件。該光源燈具是為模組化的結構,具有燈泡、反射罩、燈座以及燈杯等組成構件,該燈泡設置於該反射罩內,通過該反射罩聚集該燈泡發出的強光,以產生一投射光束朝向該光學元件照射。該燈泡主要使用如鎢鹵素燈、金屬鹵化物燈、超高壓汞燈或氙氣燈等,這些燈泡具有的共同特性就是發光強度高且明亮。因此,該燈泡的強光在通過該反射罩聚光時,都會有部分強光透過該反射罩形成雜散光。該雜散光將會通過投影機殼體的通風口進行散射,從而對影像投射螢幕以及投射環境造成影響。一般為了解決光源燈泡雜散光外漏的問題,通常會在風扇通風口與燈泡反射罩之間設置擋光片,由該擋光片遮蔽該雜散光。但是,該擋光片是一個片狀體且在通風口前設置,不但遮光的效果差同時又影響投影機的冷卻效能。如何提升遮光效果並避免影響冷卻效能,是應再加以研究予以改善。The optical engine in the structure of the projector product is an important key component, including a light source lamp and an optical component. The light source lamp is a modular structure, and has a component such as a bulb, a reflector, a lamp holder, and a lamp cup. The bulb is disposed in the reflector, and the glare emitted by the bulb is collected by the reflector to generate a light. The projected beam is illuminated towards the optical element. The bulb is mainly used as a tungsten halogen lamp, a metal halide lamp, an ultra-high pressure mercury lamp or a xenon lamp, and the common characteristics of these lamps are high luminous intensity and brightness. Therefore, when the strong light of the bulb is collected by the reflector, a part of the strong light passes through the reflector to form stray light. The stray light will be scattered through the vents of the projector housing, affecting the image projection screen and the projection environment. Generally, in order to solve the problem of stray light leakage of the light source bulb, a light blocking plate is usually disposed between the fan vent and the bulb reflector, and the stray light is shielded by the light blocking sheet. However, the light blocking sheet is a sheet-like body and is disposed in front of the vent, which not only has a poor shading effect but also affects the cooling performance of the projector. How to improve the shading effect and avoid affecting the cooling efficiency should be studied and improved.
有鑑於此,有必要提供一種遮光效果良好又不影響散熱運作的投影機燈泡固定結構。In view of this, it is necessary to provide a projector lamp fixing structure that has good shading effect without affecting heat dissipation operation.
本發明提供一種投影機燈泡固定結構,其包括一燈具模組、一第一殼體以及一第二殼體,該燈具模組包括一燈座以及一反射罩,該反射罩內具有一燈泡設置,該反射罩設置於該燈座上,該第一殼體與該第二殼體扣接構成一外殼,該外殼設置於該反射罩的外側周圍並固定於該燈座。The present invention provides a projector lamp fixing structure, comprising a lamp module, a first casing and a second casing, the lamp module comprising a lamp holder and a reflector, wherein the reflector has a bulb setting The reflector is disposed on the socket, and the first housing is fastened to the second housing to form an outer casing. The outer casing is disposed around the outer side of the reflector and is fixed to the socket.
相較現有技術,本發明投影機燈泡固定結構,通過該第一殼體以及該第二殼體組合構成的該外殼,將該外殼設置於該反射罩的外側周圍,可以完全遮蓋透過該反射罩發散的雜散光,同時可以避免阻擋投影機的散熱氣流,提高投影機的品質。Compared with the prior art, the projector lamp fixing structure of the present invention, through the outer casing formed by the combination of the first casing and the second casing, is disposed around the outer side of the reflector, and can completely cover the reflector.
