Description
Technical field
The present invention relates to a kind of LED light source block, particularly relates to a kind of high-power imaging lamp LED light source block.
Background technology
Imaging lamp is the light being polymerized to using optically focused camera lens or speculum etc..The point light type of reflectoscope is fairly simple, illumination is strong,
Spotlignt, it is easy to the lamp towards the specific position cover in scene, is a kind of lamp with the most use in film studio and studio.
But the imaging lamp of use ordinary light source is when in use, light fixture requires very high to surrounding enviroment when in use, generally in environment temperature
20 DEG C or so of degree uses for a long time, and lamp outer casing temperature can reach more than 150 DEG C, be when in use or in half an hour after of turning off the light
It can absolutely not go Touching controlling lamp body case with hand, can not have inflammable and explosive object within 5 meters of light fixture periphery during use or deposit
In potential safety hazard, and bulb life is short.
Because LED is a kind of new type light source, energy-efficient, pollution-free, long-life, safety and stability, therefore, mesh are characterized in
It is preceding generally quickly to have been applied LED as light source, this technology extensively in various smooth use occasions.Will be powerful
LED light source module, which is applied, to be focused, in the imaging lamp light fixture of zoom, under can making lamp power significantly compared to traditional tungstohalogen lamp
Drop, reach the purpose of energy-saving and emission-reduction.Market it is commonly used be traditional halogen tungsten light source and 100W-200W integrated LED light sources, form
As lamp requires that light source need to be close to spot light in actual use, single of great power LED is only 1-15W, and more integrate and make
It is larger into light-emitting area, do not reach required spot light effect.
Therefore the power density of great power LED module is improved, and solves the heat dissipation problem of LED module under high-power high density
It is the core technology that LED light source is applied to imaging lamp.At present, although the LED imaging lamps of in the market are provided with heat dissipation equipment, dissipate
