A kind of luminous indicating lamp optically focused light leak preventive apparatus
Technical field
The utility model relates to a kind of luminous indicating lamp beam condensing unit, especially plays the device of optically focused and leakproof light action when one or more lamps are realized illumination effect.
Background technology
Present existing indicator lamp Display Technique, all be around indicator lamp, lamp to be fixed with the mould device, do not have the effect of optically focused and anti-light leak, if display part one of them lamp of several lamps be easy to when bright because of light leak cause near other lamp the phenomenon of light is and then arranged, if several lamp can cause the phenomenon of the not enough or non-uniform light of display part brightness simultaneously during the various pattern of bright composition because of light leak.If there are shortcomings such as processing cost height, complex manufacturing again in the simple specification brightness that increases the measure of being in the light or increase luminous indicating lamp.
In the existing luminous indicating lamp optically focused light leak preventive apparatus, do not find identical or akin technical scheme in the field of air conditioning, but similar technical scheme is arranged in the refrigerator field, as documents 1: application number is to disclose a kind of refrigerator display part light leak preventive apparatus in 03130596.2 the Chinese patent application, the display part that is fixed on the refrigerator doors includes outwards luminous display module, the display screen that has euphotic zone of protection display module, the display part framework of display screen is installed, between the edge of the display screen of described display part and display screen installing port, is provided with light-blocking part corresponding to the display part framework at this position; Light-blocking part is provided in a side of lighttight coating on the lining euphotic zone of a side of display screen.Effect of the present invention is that the light leak preventive apparatus of refrigerator display has prevented that the light that display module sends from outwards appearing between display screen and display screen installing port, has improved the outward appearance of refrigerator, has improved the confidence level of user to refrigerator product.Mainly provide a kind of refrigerator display part light leak preventive apparatus that is used in this documents, this device prevents light leak by the band that is in the light is set, but, in this device, only be provided with anti-light transmission device, beam condensing unit is not set, so this documents does not possess the function of optically focused, remain further to be improved.
