Abstract
The invention discloses an anti-glare LED lamp and aims to provide an anti-glare LED lamp which can prevent generation of glare and weaken the light intensity of a local area. The anti-glare LED lamp comprises a lamp body (1), a radiator (2), a circuit board (3), a base (4), an LED chip (5) fixed on the base (4) and a lens (6) covering the LED chip (5), wherein the lamp body (1), the radiator (2), the circuit board (3) and the base (4) are sequentially connected; a light diffusion curved surface (7) is arranged on the inner surface or the outer surface of the lens (6); the curved surface (7) of the lens (6) can be a regular curved surface or an irregular curved surface; and the top end surface of the lens (6) is a square or a rectangle. The invention is widely applied to the field of LED indoor illumination.
Description
Technical field
The present invention relates to a kind of anti-glare LED lamp.
Background technology
Under the background that the worry of global energy shortage raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be developing tendency in future, the 2008 Beijing Olympic Games allows people that LED has been had brand-new understanding to the concentrated displaying of LED illumination, has promoted the development of Chinese semiconductor lighting industry effectively.Current Chinese semiconductor product sparetime university is not and strong, and core competitiveness still awaits further lifting.The room Design of Luminaires of 21 century will be to be main flow with the LED Design of Luminaires, demonstrates fully the illumination development trend of energy-conservationization, healthization, art up and hommization simultaneously, becomes the leading of room light culture.Research data shows that because LED is a cold light source, semiconductor lighting self, is compared with incandescent lamp, fluorescent lamp without any pollution environment, and electric energy can reach more than 90%.Under same brightness, power consumption only is 1/10 of ordinary incandescent lamp, 1/2 of fluorescent tube.If replace 50% of our present traditional lighting with LED, the electric weight that annual China saves just is equivalent to the summation of a Three Gorges plant generator amount, and its energy-saving benefit is very considerable.LED lamp DC driven does not have stroboscopic; Do not have infrared and composition ultraviolet, do not have radiation pollution, colour rendering is high and have a very strong light emission direction; Dimming behavior is good, and colour temperature can not produce the collimation error when changing; The cold light source caloric value is low, can safe touch; These all are that incandescent lamp and fluorescent lamp are inaccessible.It can provide the illumination space of comfortable, can satisfy people's physiological health demand again well, is the healthy light source of vision protection and environmental protection.The little light weight of LED light fixture volume can select for use different photochromic LED to be combined into the soft various modules of illumination, is installed in arbitrarily in the room, and the light source of room lighting may derive from ground, metope, windowsill, furniture, jewelry etc.LED is different with traditional illuminating lamp, and it has characteristics such as spot light, high brightness, arrow beam of light output, makees the LED lamp and at first will consider limited luminous flux is used effective range of exposures fully.Therefore, effectively control the distribution of light, the light that LED is sent becomes a strip light belt to be sprawled along the ground direction, also will take into account the generation of dazzle simultaneously, is the requirements at the higher level to designer's proposition of LED light.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of and prevents that dazzle from producing, and reduces the anti-glare LED lamp of regional area light intensity.
The technical solution adopted in the present invention is: the present invention includes lamp body, radiator, circuit board, pedestal, be fixed on led chip on the described pedestal, cover the lens of described led chip, described lamp body, described radiator, described circuit board, described pedestal are connected successively, and the inner surface of described lens or outer surface are provided with one deck light diffusion curved surface.
Further, the curved surface of described lens can be ruled surface or irregular curved surface.
Further, the top end face of described lens is square or rectangle.
Further, the longitudinal cross-section of described lens is an invert shape.
Further, four of described lens sides are identical.
The invention has the beneficial effects as follows: owing to the present invention includes lamp body, radiator, circuit board, pedestal, be fixed on the led chip on the described pedestal, cover the lens of described led chip, described lamp body, described radiator, described circuit board, described pedestal is connected successively, the inner surface of described lens or outer surface are provided with one deck light diffusion curved surface, the spot light that described light diffusion curved surface can send led light source spreads, reduce the luminous intensity of regional area, form uniform light, so can prevent the generation of dazzle, reduced the light intensity of regional area. because the top end face of described lens is square or rectangle, so the present invention can use effective range of exposures to limited luminous energy fully.

The specific embodiment
Embodiment one:
As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes lamp body 1, radiator 2, circuit board 3, pedestal 4, be fixed on led chip 5 on the described pedestal 4, cover the lens 6 of described led chip 5, described lamp body 1, described radiator 2, described circuit board 3, described pedestal 4 are connected successively, the outer surface of described lens 6 is provided with one deck light diffusion curved surface 7, can also be arranged on the inner surface of described lens 6 certainly.In the present embodiment, the curved surface of described lens 6 is ruled surfaces, can certainly be irregular curved surface, and the top end face of described lens 6 is square or rectangle, the coverage of light is big, the longitudinal cross-section of described lens 6 is an invert shape, and four sides of described lens 6 are identical, and the light that LED sends is through described lens 6, described lens 6 form a big area source, therefore the direction of arrow signal light, looks and can not feel dazzling.The light that LED sends owing to be provided with one deck light diffusion curved surface 7 at the outer surface of described lens 6, so the light that LED sends can be broken down into many light, makes LED shine out with dazzling brilliancy line because scatter through described lens 6, can not seem dazzling.
Embodiment two:
As shown in Figure 4, the difference of present embodiment and embodiment one is: present embodiment comprises four led chips 5, four lens 6, each described led chip 5 one of outside installation is provided with the lens 6 of one deck light diffusion curved surface 7, only need to install a described radiator 2, described circuit board 3, described pedestal 4, described radiator 2 is fixedlyed connected with described circuit board 3, described pedestal 4, and described led chip 5 is fixed on the described pedestal 4.Present embodiment can be regulated the quantity and the brightness of led chip according to the size of the interior space, can be combined into a light fixture by the led chip 5 that a plurality of lens 6 are housed.Be provided with at a plurality of light sources on the pedestal 4 that described led chip 5 is housed on the lens 6 of one deck light diffusion curved surface 7 and forming numerous bright spot, whole described lens 6 seem to be exactly a huge light source, and therefore the mode of this disperse light makes people can not feel dazzling.
The present invention is widely used in LED room lighting field.
