Description
Technical field
The present invention relates to a kind of projection arrangement; Be particularly related to a kind of pendulum position that utilizes solar panel,, assist the inner colded projection arrangement of body to form the air channel.
Background technology
Heal to become under the condition of limited at the energy, how development in science and technology takes into account energy economization and environmental issue, has been an important subject under discussion.In the luminescence technology of projector, not only need consider light source with the efficient of corresponding electric energy, for the quality of asking whole projection arrangement improves, also need consider some other factors, for example: the surplus light to the projection arrangement external diffusion must be covered as far as possible, in order to avoid light stimulates the user; The non-light that projection is provided as far as possible effectively utilizes; And/or the height that light source works is given birth to is warm, should effectively be got rid of.
The consideration of aforementioned several factors with the research and development of present projection arrangement, has its independent technique improvement all respectively.For example, special baffle plate is set to cover surplus light; Solar panel is set, absorbs the function of surplus light, and it effectively is converted to electric energy, additional feed projection arrangement required electric power with performance.This technology can be with reference to No. the 6th, 467,910, the United States Patent (USP) of on October 22nd, 2002 bulletin, and it is the leakage astigmatism that absorbs the projection arrangement light source by solar cell, and is converted into the technology of electric energy.Another kind of design, be for the form of radiator fan itself and and light source between relation, improve, to promote its cooling effectiveness.Only aforesaid independent technique improvement, not only increase manufacturing course, material and assembling and go up outside the complexity, and all can't reach the scheme that once solves simultaneously at all about shading, energy utilization, and the problem of body cooling.And if the relation between above-mentioned these independent design is not considered in advance, very likely cause the conflict that designs, cause the Expected Results of its original design, have a greatly reduced quality.
Fig. 1 concerns synoptic diagram for the inner member setting of known a kind of projector 1, and this projector 1 inside is provided with light engine 11, light fixture 13, power panel 15 (Power Board), apparatus for lighting up 17 (Ballast) and two cooling fans 19.Wherein, the air draft effect of this cooling fan 19, can produce cooling airflow 12, each element in order to cooling projector 1 inside, this cooling airflow 12 can be because cooling fan 19 be set up in parallel, and no isolated component interferes with each other the phenomenon of pullling and produce air-flow, this phenomenon can be unfavorable for that cooling airflow 12 forms the runner of needs of cooling institute, thereby the attenuating heat dissipation.
As previously mentioned, the design of projector at present or have do not utilize light source (being surplus light) and projector's light from outside to be converted into the design of electric energy etc. with projector inside, but heat dissipation problem still needs other consideration, not only it increases inner member quantity, also increase the mould complexity, and then increase manufacturing cost.
In view of this, providing and utilize existing element, to reach shading, energy utilization simultaneously, and to strengthen the body cooling purpose, is industry problem demanding prompt solution for this reason.
Summary of the invention
