Technical field:
The utility model relates to the condenser system in a kind of lighting device, refers to a kind of high-power LED concentration system of being made up of ellipsoidal mirror and condenser group especially.
Background technology:
At present, LED is as a kind of new type light source, have that power consumption is low, heating less, advantages such as luminous efficiency height, pollution-free, energy-conserving and environment-protective and long service life, so LED is widely used in lighting field.Yet because the power of single LEDs can not be done very greatly, therefore will obtain bigger luminous flux must could realize with many great power LED combinations.In the light fixture commonly used such as optical systems such as projection magic lamp, projector, cinematographic projector or follow spot light in the general video display illumination, all adopt ellipsoidal mirror as condenser system.The condenser system of traditional video display lighting as shown in Figure 1, light source are placed on first focal point F of ellipsoidal mirror
1The place, irradiates light is pooled to second focal point F through the ellipsoidal mirror reflection
2The place, the point of light source is good more, and system's light efficiency is just high more.And led light source needs many spot lights to compile the luminous flux that just can reach needs, can't form a single point light source, therefore can not directly use ellipsoidal mirror as high-power LED concentration system.How to allow the mutual superposition of plurality of LEDs irradiates light form spot light, become the design difficulty of LED condenser system, this difficult point is if can not get solving the needs that just can not satisfy high-power LED concentration system.
Summary of the invention:
The purpose of this utility model is to solve the problem that single LEDs power is little, luminous intensity is not enough that the LED condenser system exists, a kind of high-power LED concentration system that utilizes the organization plan formation of ellipsoidal mirror and condenser group is provided, allow the mutual superposition of plurality of LEDs irradiates light form spot light, to reach the luminous flux that needs, satisfy the needs of high-power LED concentration system.
The utility model is by the following technical solutions:
A kind of high-power LED concentration system, form by ellipsoidal mirror and many group LED modules, the LED module evenly is arranged at the periphery of ellipsoidal mirror, is provided with the condenser group at the exiting surface of each LED module, and this condenser group is made up of condenser outer cover and the lens that are installed in the condenser outer cover; Opposite face at ellipsoidal mirror is provided with a condenser support, and described condenser support is provided with the installing hole of different angles, and each condenser group is flush-mounted in respectively in the installing hole of condenser support.
Adopt the technical solution of the utility model, light from each LED module is converged to the ellipsoidal mirror first focus place by the condenser group of correspondence, reflex to the second focus place by ellipsoidal mirror again, in like manner will organize the LED light beam more and all converge to the first focus place through corresponding condenser group, reflex to the second focus place by ellipsoidal mirror again, allow the mutual superposition of many group LED light form spot light, substitute light source point (prior art condenser system first focal point F as shown in Figure 1 of traditional condenser system
1The light source at place), makes full use of the light output of respectively organizing led light source, solved the problem that single LEDs power is little, luminous intensity is not enough, reach the luminous flux that needs, realized the needs of high-power LED concentration system.
The beneficial effects of the utility model are:
1, with the condenser group single led module irradiates light output is pooled a spot light, and will organize the condenser group more and be circumferential arrangement along the ellipsoidal mirror periphery, the spot light superposition that makes all LED modules formation is in the ellipsoidal mirror first focus place, form a virtual spot light, solved many groups LED since reasons in structure can not superposition a difficult problem.
2, the light output of respectively organizing LED evenly reflexes to the second focus place by ellipsoidal mirror again after first focus, has made full use of the light output of respectively organizing LED.
