Technical background
LED has advantages such as light efficiency height, life-span length, nontoxic no electromagnetic pollution, belongs to typical green illumination light source.The LED light fixture has begun to be used widely in fields such as commercial lighting, indoor and outdoor lighting, and it just progressively replaces incandescent lamp, Halogen lamp LED as the key lighting light source as a kind of light source efficiently.
LED light emitting module commonly used on the existing market comprises substrate, connect LED by control circuit on the substrate, the characteristics of luminescence of this class LED light emitting module is lambert's type, as shown in Figure 1, can be luminous in positive 90 ° and negative 90 ° of scopes (promptly 180 ° in luminous), the angle of divergence is 120 °.This class LED light emitting module can satisfy conventional lighting demand, but at special lighting field, as when being used for throwing light on the luminous bulb lamp of wide-angle in the three-dimensional scope of some needs, the Crystal lamp, above-mentioned LED light emitting module just can't satisfy lighting requirement.Another kind of LED light emitting module, at LED outer setting lens, these class lens only have the plane of incidence and exit facet, only play the optically focused effect usually, can not enlarge illumination range.
The utility model content
The utility model provides a kind of LED light emitting module at the defective that prior art exists, and can effectively increase the illumination range of LED, enlarges applicability, and is rational in infrastructure, easy to make.
For this reason, the utility model is taked following scheme: a kind of LED light emitting module, comprise substrate, LED is installed on the substrate, it is characterized in that described LED is provided with lens outward, described lens are is rotating shaft with the central axis, rotate the rotary body that curved surface was surrounded that forms with bent limit, the upper surface central part of lens forms exit facet, outer part forms fully reflecting surface, and the sidewall of lens forms two exit facets that bend mutually that cave inward, and the bottom surface of described body forms the plane of light incidence of indent.On the lens upper surface, form a fully reflecting surface, make and reflex on the exit facet of lens both sides through this fully reflecting surface from the light of bottom surface incident, penetrate lens through exit facet again, the more part of light of this part ejaculation lens can be distributed in the negative direction area of space perpendicular to the lens centre axis, has effectively enlarged the illumination zone of LED light emitting module.
The exit facet of described lens upper surface is first plane of refraction, and the zone that described lens upper side wall links to each other with fully reflecting surface is second plane of refraction, and the zone that described lens lower wall links to each other with second plane of refraction is the third reflect face.Light reflects lens through first plane of refraction distribution of light the lens centre axis and with the area of space of central axis angle less than 45 °; The distribution of light that reflects lens through the 3rd plane of refraction perpendicular to the lens centre axis and with the area of space of central axis angle greater than 30 °.The light that reflects from first plane of refraction and third reflect face of light is guaranteed to be distributed within 0 ° to 180 ° region-wide like this, makes the light emitting module of this patent can satisfy conventional lighting demand.
Described first plane of refraction is an inner sunken face, and inner sunken face is compared the light that horizontal plane can make LED send and obtained better dispersion angle, and illumination zone is wider.
The central area sunken inside of described lens bottom surface becomes the semicircle sphere, can allow the luminous energy that LED sent all incide lens.
Apply minute surface coating on the outer surface of described fully reflecting surface, described minute surface coating is circular, and the zone applies minute surface coating between first plane of refraction and second plane of refraction, avoids making the part light refraction go out air owing to lens are aging and causes light to run off.
The material refractive index of described making lens is 1.3-1.7, and the material of described making lens is COC, PMMA, PC, transparent materials such as resin.
The beneficial effects of the utility model are embodied in: in the exterior arrangement of LED one piece of special lens, make a fully reflecting surface in the part of lens upper surface, after making the light that sends from LED by the fully reflecting surface reflection, plane of refraction from the lens both sides reflects again, the distribution of light of this part process reflection and refraction is at the negative direction area of space perpendicular to the lens centre axis, effectively enlarged the illumination zone of LED light emitting module, the angle of divergence of this class LED light emitting module can reach more than 270 °.According to the demand of actual illumination scope, also can when making lens, change the zone that fully reflecting surface covers, to reach the purpose that changes illumination range, adapt to all kinds of lighting demands.

The specific embodiment
Below in conjunction with specification drawings and specific embodiments substantive distinguishing features of the present utility model is further described.
As Fig. 2, LED light emitting module shown in Figure 3, mainly constitute by the substrate 3 of LED 2, carrying control LED2, the control circuit and the radiating piece that connect LED2, LED2 is nested with lens 1 of being made by transparent materials such as COC, PMMA, PC or resins outward.Lens 1 are is rotating shaft with the central shaft, rotate the rotary body that curved surface was surrounded that forms with bent limit.Locate mutually with the top base shape of substrate 3 bottom surface of lens 4, so that install, be bearing on the substrate.The bottom surface 4 zone line sunken insides of lens 1 become the plane of incidence 9 of semicircle sphere.The upper surface central part of lens 1 forms exit facet, and outer part forms fully reflecting surface 8, and the outer surface of fully reflecting surface 8 applies minute surface coating, and minute surface coating is circular, and lens 1 sidewall forms the exit facet that caves inward.Wherein the exit facet of lens 1 upper surface is first plane of refraction 5, the zone that lens 1 upper side wall links to each other with fully reflecting surface 8 is second plane of refraction 6, the zone that lens 1 lower wall links to each other with second plane of refraction 6 is a third reflect face 7, and first plane of refraction 5 is an inner sunken face, the material range of refractive of making lens is 1.3 to 1.7, can pass through processes such as rapid shaping, injection moulding.
