Abstract
The utility model discloses an LED (light emitting diode), comprising a lamp cup, a lens, a lamp cap, a power supply, an LED and a PCB (printed circuit board) substrate, wherein the lamp cap is mounted at the bottom of the lamp cup, the power supply is connected with the lamp cap, the lamp cup is a bowl-shaped housing, the PCB substrate is fixed in the bottom of the lamp cup, the LED is welded on the PCB substrate, the lens is arranged above the LED and is fixedly connected with the lamp cup, the lens is a circular arc-shaped base body, the base body comprises a bottom incident surface, a reflecting surface with a circular arc-shaped outer surface, and a top light emergent surface, multiple small polygonal reflecting surfaces are uniformly arranged on the reflecting surface of the base body according to the radian of the reflecting surface, the reflecting surface of the lens of the LED spotlight is designed into small quadrilateral arc surfaces or polygonal arc surfaces, so as to increase the reflecting surface, an output light spot is accordingly increased, and the output light ray is uniform and is not glaring.
Description
Technical field
The utility model relates to the lens of the LED shot-light of LED apparatus field.
Background technology
In existing background technology, the luminous intensity distribution of LED shot-light has the lens of employing and reflector dual mode.Lens generally go out light characteristic design according to LED, make the lighting angle about 120 degree become the low-angle that needs, such as 24 degree or 36 degree or other angles.Some LED joins lens, and perhaps several LED join a compound lens.Finally reach the effect of luminous intensity distribution.This luminous intensity distribution technology has just simply changed the lighting angle of LED, does not consider the uniformity of lens output facula, and the comfortableness of human eye.
Chinese patent New LED lens publication number is CN101881412A, a kind of New LED lens is disclosed, what it adopted is that array way is arranged a plurality of LED lamps on circuit board, the New LED lens that it uses, it is provided with a plurality of annular grooves concentric with the LED minute surface on the outer surface of lens, described annular groove enlarges from inside to outside gradually, it is characterized in that: lens are the semicircle arcuation, there is the setting of optically focused ring in appearance section at lens, changes patent by the improvement to outer surface, increases spotlight effect, but still do not solve the uniformity of lens output light class, have much room for improvement.
The utility model content
The utility model provides the LED that a kind of spotlight effect is good, output facula is even, comfort level is high shot-light to solving the problems of the technologies described above.
the utility model is for the deficiencies in the prior art, provide following technical scheme: a kind of LED shot-light, comprise Lamp cup, lens, lamp holder, power supply, LED, the PCB substrate, described lamp holder is installed on bottom Lamp cup, power supply connects lamp holder, described Lamp cup is the bowl-type housing, the PCB substrate is fixed on the bottom in Lamp cup, described LED is welded on the PCB substrate, lens are fixedly connected with Lamp cup above being arranged at LED, it is characterized in that described lens are the circular arc matrix, matrix comprises the incidence surface of bottom, the reflecting surface of circular arc outer surface and the exiting surface at top, the matrix reflecting surface evenly offers the little reflecting surface of a plurality of polygons according to its radian.
As preferably, described little reflecting surface is quadrangle or pentagon.Increased reflecting surface by this kind setting, increased output facula, made output light even, light is not dazzling.
For better explaining the technical solution of the utility model, below introduce know-why of the present utility model: the effect of the components and parts that the utility model is introduced: 1, Lamp cup: the main components that is shot-light, it is also the heat radiation major part of LED light source, being directly connected to the part in LED shot-light life-span, is also the major part of shot-light profile simultaneously.
2, lens: be the luminous intensity distribution part of spotlight light source, determined rising angle and the illuminating effect of shot-light.
3, lamp holder: the selection that is shot-light and external electrical connected mode.
4, power supply: the electric driving part that is spotlight light source.
5, LED: the light source that is shot-light.
6, PCB substrate: the part that is shot-light welding light source.
At first LED is welded on the PCB substrate, and the PCB substrate is fixed on Lamp cup, and power supply also lamp holder connects, and then lamp holder and Lamp cup are screwed again, and last lens are fixed on Lamp cup, form so a complete LED shot-light product.
When the utility model carries out work, the light source of LED enters substantially from the entrance port of lens, reflect by reflecting surface, enter eyes by exiting surface at last, the utility model is done reflection from lens face the polygonal modes such as quadrangularly or pentagon, and the light-emitting area of exiting surface is increased, similar reflector go out light effect, make LED shot-light output light transition even, naked eyes are not dazzling.
The beneficial effects of the utility model: the little cambered surface of the utility model by the reflecting surface of LED shot-light lens being done quadrangle or some limits shape increased output facula to increase reflecting surface, makes output light even, and light is not dazzling.
