Abstract
The utility model discloses a high-power LED module used on an optical system of a projector. The high-power LED module comprises a plurality of single LED chips which are reflow soldered on a coppersubstrate, and the space between the adjacent single LED chip edges is less than 1mm. In the utility model, the LED module is adopted as the light source of the projector, and the volume is far smaller than that of a bulb module and a cooling system used for the projector, so that the LED module can achieve lighting once starting up, cooling is carried out without waiting for shutting down, the calorific value is not large, and the service life is long. The space between the chip edges of the current LED is decreased to be less than 1mm, after decreasing, the luminous flux output of the projector can be proportionally improved for the LED module with the same power and photoelectric parameters, and the utilization ratio of the optical system of the projector is improved; meanwhile, as thelight-emitting area of the light source is decreased, the image contrast and the focusing precision are also evidently improved.
Description
Technical field
The utility model relates to a kind of light source that is used for projector.
Background technology
No matter projector is as the instrument in commercial affairs and the education demo environment, still realize the equipment of large scale picture output as family, all to note heat radiation in the use, note power supply, note many items such as dustproof.The light source of projector is very big to the performance of projector and price influence, and is again running stores, and projector can not work long hours, otherwise the brightness meeting of its bulb decays, and this will directly influence its life-span.The light source of present employing mainly comprises: UHP lamp (super lamp), UHE lamp and metal halid lamp.The UHP bulb is a kind of desirable cold light source, but because price is higher, generally is applied in the high-grade projector; The UHE bulb also is a kind of cold light source, moderate cost, but service life is short; The heating of metal halogen bulb is high, and heat radiation system of projector is required height, is unfit to do long-time projection and uses.Projector based on led light source has represented development in future trend, but the spacing between now used each chip edge of led light source is 1mm, projector's brightness of using led light source is generally all about 100 lumens, compare with the brightness of traditional projector thousands of lumens and also not possess competitiveness, the luminous utilization ratio problem of LED becomes the bottleneck of restriction led light source projector development always.
The utility model content
The purpose of this utility model is to provide a kind of can be used, can improve the picture contrast of projector for a long time and focus on the great power LED module on the projection machine optical system of being used for of accuracy.
This great power LED module that is used on the projection machine optical system that the utility model provides comprises the single LEDs chip of several reflow solderings on copper base, and the spacing between each adjacent single LEDs chip edge is below 1mm.
The utility model adopts the light source of LED module as projector, volume is small and exquisite more than projector used bulb module and cooling system, the preheating time that does not need bulb, can accomplish that start is promptly bright, and heat radiation to be shut down such as need not, caloric value is little, and long service life can need not to consider the cost that more changes the bulb and paid in time several years.The utility model narrows down to the spacing between each chip edge of present LED below the 1mm, after dwindling, for the LED module of same power and photoelectric parameter, the luminous flux of projector is exported the raising that can obtain being directly proportional, and has improved the utilization rate of projection machine optical system.While, picture contrast and focusing accuracy also were significantly increased owing to the light source luminescent area reduces.
Description of drawings
Fig. 1 is the structural representation of the utility model LED.
The specific embodiment
This great power LED module that is used on the projection machine optical system that the utility model provides, comprise several single LEDs chips 1, copper base 2,1 one-tenth matrix form of these single LEDs chips is arranged and is welded on the copper base 2, and the spacing between described each chip 1 edge is below 1mm.
After spacing between each chip is dwindled, the LED of same power and photoelectric parameter, the raising that the luminous flux output of projector can obtain being directly proportional.For example: the led chip that with the individual particle is 1W is an example, and the spacing between each chip 1 edge narrows down to 0.5mm, and the output of projector light flux can improve about 1.33 times; Narrow down to 0.05mm, can improve about 1.66 times, reach the output of same luminous flux, the LED power that needs reductions that be directly proportional reached purpose energy-conservation and the saving cost.
After it should be noted that spacing between each chip is dwindled, its encapsulation is compacter, and the heat during work can strengthen, and needs to adopt cooling measure, and the heat radiation way of employing has following 3 points: the one, and strengthen area of dissipation to 20 and divide equally centimetre/watt, the air blast cooling heat radiation; The 2nd, adopt the Japanese KS609 of SHIN-ETSU HANTOTAI type CPU specialty silicone grease; The 3rd, adopt stainless steel screw fastening.To the consideration of thermal resistance, realized optimal state during design, junction temperature rise has been controlled in 30 degrees centigrade, is far superior to the other industry standard, and through test in 20000 hours, reaches instructions for use.
