Abstract
The utility model provides a fluorescent tube simulated LED tubular lighting device. Light source plates provided with LED arrays are attached in the groove body in the inner surface of a base in a non-coplanar arrangement manner, the distance of each LED array to a light-uniformity lampshade is substantially equal, thus, the aims of light uniformity and glare elimination can be easily achieved. Because the orientation of each LED array is different, the light outputting angle of a tubular lamp body is further increased and the light outputting rate is improved. The lighting device provided not only improves the light beam angle, the uniformity, and the light extraction efficiency of the output light of the LED light source, but also improves the heat radiation of the LED light source to prevent the LED light source from early light attenuation due to overheating, thereby really embodying the characteristics of energy saving, and long service lifetime of LED lighting products.
Description
Technical field
The utility model relates to a kind of LED tubulose lighting device of simulating fluorescent lamp, refers in particular to a kind ofly to convert LED point light the lighting device of similar fluorescent lamp tubulose light effect to, is used for the lighting unit of indoor conventional illumination or other commercial uses.
Background technology
Be widely used in the lighting unit of indoor conventional illumination or other commercial uses at present; The lighting unit that great majority are made up of single of use or manifold shape fluorescent lamp; In recent years released the product of a type " LED fluorescent lamp " on the market, its objective is a led light source circuit board is set on the fluorescent tube that is utilized in similar fluorescent lamp, LED becomes a row or the arrangement of multi-in-line property; Intention forms simulation fluorescent lamp tubulose light effect and simulation fluorescent lamp profile, to substitute traditional tubular fluorescent lamp.Just because of adopted the tubular structure and the conduction lamp holder of simulation fluorescent lamp, can be installed in easily in conventional fluorescent lamp bracket or the light fixture, therefore extensively adopted by numerous LED illumination enterprise; Yet because LED is a spot light, center brightness is higher; As adopt Transparent lamp tube can form dazzling bright spot and dazzle; Therefore, in order to eliminate the LED bright spot, bring into use in the industry translucent fluorescent tube with even light action.Yet, adopt the higher fluorescent tube of transparency, can clearly see the bright spot of LED in the fluorescent tube or the dark space between the LED, though adopt the lower fluorescent tube of transparency can the bright spot of LED be eliminated, overall brightness greatly reduces.Therefore many row LED are set become the industry first-selection with the effect that reaches the brightness that increases such fluorescent tube.
China utility model patent ZL201020522672.6 discloses a kind of modification method of light emitting diode simulation fluorescent lamp, and its purpose of design is that the led light source plate is arranged on the cross section of tubulose, places the translucent fluorescent tube 101 of its even light action on it.The main utility model purpose of this patent is the tubular light that the point-like analogy that is used for LED becomes fluorescent lamp; Yet; This patent has just been pointed out a kind of straightforward procedure that the arrangement of LED point light property is converted to simulation fluorescent lamp tubulose light; And adopted many rows LED increasing the design of brightness, emphasis is to have solved simulation fluorescent lamp tubulose light effect and considered to make its problem that reaches suitable brightness, but the even light of this patent prompting and the problem of heat radiation do not have solution preferably.Can find out that from this patent specification and accompanying drawing thereof it adopts the LED of surface attaching type, its lighting angle (refers to the angle between its brightness center to half intensity; Left and right sides angle sum) the industry common-use size is 120 degree, when being used for arranging LED, because two row's light sources of led light source plate are to be planar alignment more; No matter in pipe, how far be separated by, do not change the angle that forms between two row's led light source light, led light source places tubular body 102 in addition; In fact the LED on the different rows is also unequal to the distance of tubular body wall; Therefore from tube wall far away can't see bright spot, but see bright spot from the nearly LED of tube wall, like the distance of whole increasing LED; The output light efficiency will reduce again greatly, so this patent is not pointed out the technical scheme of even light preferably.Therefore this patent had not both solved the problem of delivery efficiency, did not strengthen the output angle of light yet.
