Abstract
The utility model discloses a light distributing lens of big power LED tube light, which comprises a lens body, wherein the lens body is installed on the inner surface of the outer shell of an LED tube light, the upper end surface of the lens body is the frosted surface, the frosted surface is formed through the membrane spraying technology, the surface has high light transmittance ratio compared with a common frosted surface, straight line light of an LED is changed into the fixed direction scattering, an original LED light is uniformly scattered, the shooting angle is enlarged, the shooting range of light is increased, and simultaneously the LED glare is eliminated, the floor light spots are eliminated, and the approximate surface lighting effect is formed.
Description
Technical field
The utility model relates to a kind of high-power LED tube light, relates in particular to a kind of light-distribution lens of high-power LED tube light.
Background technology
Current, the high-power LED Down lamp is for increasing the LED brightness, the lower end inner surface that its LED Down lamp light distribution device is a LED Down lamp shell 11 is provided with a collector lens body 10 (see figure 2)s, owing to be provided with collector lens, so, not only reduced range of exposures, and, can cause ground hot spot phenomenon because collector lens is concentrated light.
The utility model content
The utility model is at deficiency of the prior art, provide a kind of light distribution effect good, can increase range of exposures, eliminate the light-distribution lens of the high-power LED tube light of ground hot spot phenomenon.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of light-distribution lens of high-power LED tube light comprises lens body, and lens body is installed on the inner surface of LED Down lamp shell, the upper surface of described lens body is a matte surface, adopt the spray membrane technology to form matte surface, the common frosting light transmittance of this surface ratio height is changed into directional scattering with LED straight line light, the even scattering of former LED light, enlarge irradiating angle, increase the light range of exposures, eliminate LED simultaneously and dazzle light, eliminate the ground hot spot, form approximate face illumination effect.
In the technique scheme, the lower surface of described lens body is a spherical end surface, and the optically focused effect of its generation the light-ray condensing directive ground that scatters to surrounding space that frosting forms, is so promptly eliminated the light of dazzling of hot spot and light source, has made full use of luminous flux simultaneously.
In the technique scheme, the protruding upper surface in the described matte surface is spherical.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
1) the light-distribution lens inner surface of high-power LED tube light adopts the spray membrane technology to form matte surface, the common frosting light transmittance of this surface ratio height, LED straight line light is changed into directional scattering, the even scattering of former LED light, enlarge irradiating angle, increase the light range of exposures, eliminate LED simultaneously and dazzle light, eliminate the ground hot spot, form approximate face illumination effect;
2) utilize the optically focused effect of the convex mirror of lens outer surface simultaneously,, so promptly eliminate the light of dazzling of hot spot and light source, made full use of luminous flux simultaneously the light-ray condensing directive ground that scatters to surrounding space that frosting forms.
Description of drawings
Fig. 1 is a high-power LED tube light light-distribution lens front view
Fig. 2 is a high-power LED tube light light trend graph in the prior art
Wherein the projection in the matte surface 2 because size is less, is handled as amplifying during drawing.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
See Fig. 1, the light-distribution lens of described high-power LED tube light is mainly by lens body 1, and the projection that is arranged on the lens body 1 is formed.
Described lens body 1 end face is a matte surface 2, the end face of the projection 20 in the described matte surface 2 is spherical, described this matte surface 2 adopts the spray membrane technology to form, and the common frosting light transmittance of this surface ratio height is changed into directional scattering with LED straight line light, the even scattering of former LED light, enlarge irradiating angle, increase the light range of exposures, eliminate LED simultaneously and dazzle light, eliminate the ground hot spot, form approximate face illumination effect;
The lower surface globulate end face of described lens body 1, also, the lower surface is a convex mirror, the optically focused effect of its generation, the light-ray condensing directive ground that scatters to surrounding space that frosting forms, so promptly eliminate the light of dazzling of hot spot and light source, made full use of luminous flux simultaneously.
