Description

The illumination module structure

Technical field

The utility model relates to a kind of illumination module structure, particularly a kind of ghost image phenomenon that is taken place when avoiding this light emitting diode of most simultaneously luminous, and can obtain that illumination is good, illumination is even, do not have the illumination module structure of yellow aberration, illumination offset.

Background technology

Existing light fixture all is to use bulb or the fluorescent tube light emitting source as light fixture, and cooperate one to have color and lampshade that can transmitted light, make light after appearing lampshade, can form different colors, the shortcoming of this kind conventional lamp structure is exactly power consumption, easily heating and life-span are short, have again after lamp is spoilt, the function of illumination just no longer is provided, and the light that the bulb that has sends must appear lampshade, can cause the brightness of light to descend, so increasing in recent years light fixture, successively with light emitting source from traditional bulb, made light emitting diode (light emitting diode into, LED), traffic lights on the road, flashlight, ornament lamp or the like, all used instead light emitting diode module come luminous, as for Vehicular lamp such as automobile tail light and brake lamp or the like, also adopt light emitting diode module already in a large number, this is because light emitting diode has low power consuming, economize the energy, life-span is long, durable, shatter-proof, volume is little, react advantage such as fast.

Above-mentioned light emitting diode is because light-emitting area is little, the light source convergence that is sent is a spot light, be applied to lamp box or during as the output of general light source, its light source has the uneven situation of output and takes place, especially be applied in the lamp box of thinner thickness or be applied in the photography aspect use lamp the time, because such required light source need just reach the light source of uniform luminance in short distance, make the use of this light emitting diode be restricted, and has reduced the coml value.

So there is the dealer to be provided with lens at the front end of LED source, the inhomogeneous light output of light emitting diode is converged in the certain area coverage, make it reach light source output comparatively uniformly in the regional area, but such mode still must make LED source and shadow surface maintain enough distances, just can reach the preferable even purpose of light, distance between light source and shadow surface very in short-term, still have tangible light source non-uniform phenomenon, making only utilizes these lens that light emitting diode is carried out improved optics, the thickness that will cause lamp box and various lighting apparatus, volume is restricted in design, see through the light source of the light emitting diode that lens lighting goes out simultaneously, the offset that can have obvious illuminance in its edge, and also can have the phenomenon of tangible yellow aberration, make its comparatively inconvenience that seems in the use.

Also there is the dealer to utilize diffusion barrier in addition, is provided with diffusion barrier, the inhomogeneous light of light emitting diode can be obtained light source output comparatively uniformly through this diffusion barrier at the LED source front end; But, the mode that this utilizes diffusion barrier that LED source can comparatively evenly be exported, its light source that sends makes that the light source light illumination on shadow surface is obviously not enough owing to do not pass through the gathering of lens, causes its practicality not good.

If utilize lens that the inhomogeneous light output of light emitting diode is converged in the certain area coverage earlier, making it reach higher light source via diffusion barrier again exports under the uniform situation, will cause the height the light source scattering phenomenon, though make the light source that is radiated on the shadow surface reach the preferable uniformity, irradiated area increase, but its illuminance significantly weakens, and can't solve the yellow aberration problem of light source edge fully.

The utility model content

The purpose of this utility model is to provide a kind of illumination module structure, this illumination module structure has diffusion barrier, help light emitting diode that a uniform surface light source is provided, the ghost image phenomenon that is taken place when avoiding this light emitting diode of most simultaneously luminous, and the outside of diffusion barrier also can set firmly lens, make the light that light emitting diode sent to spread via diffusion barrier earlier, light after will spreading again utilizes lens to be assembled and adjusts the light type, and can obtain that illumination is good, illumination is even, and do not have the illumination of yellow aberration, illumination offset.

To achieve these goals, the utility model provide a kind of illumination module structure its mainly have a heat sink, be equiped with a most light emitting diode on the heat sink, and on heat sink, be installed with a reflector, the reflector frame encloses the outside in light emitting diode, can reflect the light that light emitting diode sends and increase whole brightness, and the drift angle angle of reflector can determine the irradiating angle of this light emitting diode, the other end in reflector is installed with a diffusion barrier again, help this light emitting diode that a uniform surface light source is provided, the ghost image phenomenon that is taken place when avoiding this light emitting diode of most simultaneously luminous.

Above-mentioned illumination module structure, wherein, this light emitting diode is arranged in matrix.
