Abstract
The utility model discloses a wide-angle LED daylight lamp which comprises a radiating aluminum tube, a lampshade and lamp holders. The lamp holders are arranged at two ends of the radiating aluminum tube, and the radiating aluminum tube comprises a semi-tube-shaped cover and a light source plate axially arranged in the semi-tube-shaped cover. The wide-angle LED daylight lamp is characterized in that the light source plate comprises a horizontal plate and inclined plates respectively connected to two sides of the horizontal plate, the horizontal plate and the two inclined plates are respectively parallelly provided with a PCB (printed circuit board) substrate, and at least one LED luminous chip is arranged on each PCB substrate. The wide-angle LED daylight lamp has the advantages that the luminous angle of the LED daylight lamp is larger, dark zones on two sides of the lamp are avoided, and the luminous effect of the wide-angle LED daylight lamp is closer to that of a fluorescent lamp. Besides, the wide-angle LED daylight lamp is simple in structure and high in practicality, and facilitates batch production.
Description
[technical field]
The utility model relates to the LED technical field, particularly a kind of extensive angle LED fluorescent lamp.
[background technology]
The lighting of convention comprises incandescent lamp, fluorescent lamp, Metal halogen lamp, LED lamp etc., wherein, and incandescent lamp, fluorescent lamp low price; Performance can satisfy the demand of general domestic consumer, deeply Chinese rural area etc., but its life-span of incandescent lamp is short; Electro-optical efficiency is low, contains infra-red radiation and is prone to broken; Fluorescent lamp contains infrared ray and ultraviolet ray, heavy metal Hg, and not environmental protection has limitation service life; And the Metal halogen lamp that occurs in succession can reach 100LM for every watt, and the colour developing row is higher than 90, but 1000 hours its service life; Along with further developing of lighting technical field, led light source because of have use low-tension supply, power consumption less, strong, the stability height of applicability, response time weak point, environmentally safe, advantage such as multicolor luminous, become main flow lighting source of new generation; LED has replaced existing incandescent lamp, fluorescent lamp etc. gradually as the LED fluorescent tube of lighting source, LED bulb lamp etc.; Yet LED fluorescent lamp of the prior art, its LED luminescence chip are fixedly installed on the installing plate in the lamp housing; Its lighting angle is less; Only have about 120 °, the dark space of light fixture both sides is bigger, has certain defective.
[utility model content]
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of lighting angle big, the extensive angle LED fluorescent lamp of light fixture both sides no dark space.
The purpose of the utility model is to realize like this: it comprises heat radiation aluminum pipe, lampshade and is arranged at the lamp holder at heat radiation aluminum pipe two ends; Said heat radiation aluminum pipe comprises semicanal female cap body and is axially set in the light source board in the semicanal female cap body; Its improvement is: said light source board comprises level board and is connected to the hang plate of level board both sides; Be separately installed with a PCB substrate on said level board and two hang plates, be provided with a slice LED luminescence chip at least in said PCB substrate;
In the said structure, said two hang plates and level board are one-body molded, form an opening upwards, its upper width is greater than the groove body type structure of lower width;
In the said structure, said two hang plates and level board angulation are respectively 120 ° ,-120;
In the said structure, said two hang plate top edges are fixedly connected on the inwall of heat radiation aluminum pipe.
The utility model beneficial effect is: the utility model is through being designed to light source board to have the structure of hang plate, and promptly light source board comprises level board and is connected to the hang plate of level board both sides, is separately installed with a PCB substrate on level board and two hang plates; Be provided with a slice LED luminescence chip at least in said PCB substrate; So, make the lighting angle of LED fluorescent lamp enlarge, reduced the dark space of light fixture both sides; Further; Said two hang plates and level board angulation are respectively 120 ° ,-120, by this, make the lighting angle of LED fluorescent lamp maximize; Eliminated the dark space of light fixture both sides, the illumination effect of this LED fluorescent lamp is more near the illumination effect of fluorescent lamp; In addition, it is simple in structure, is convenient to produce in batches, and is practical.

Fig. 2 is the left view of the utility model.
[specific embodiment]
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
Referring to figs. 1 through shown in Figure 2; The utility model has disclosed a kind of extensive angle LED fluorescent lamp; It comprises heat radiation aluminum pipe 1, lampshade 2 and is arranged at the lamp holder at heat radiation aluminum pipe 1 two ends; Lampshade 2 is sheathed on the heat radiation aluminum pipe 1 and forms the circular lamp shell structure, and said heat radiation aluminum pipe 1 comprises semicanal female cap body and be axially set in the light source board 3 in the semicanal female cap body that promptly light source board 3 vertically is fixedly arranged in the circular lamp shell structure; Said light source board 3 comprises level board 302 and is connected to the hang plate 301 of level board both sides; Two hang plates 301 are one-body molded with level board 302, and level board 302 and two hang plates 301 form an opening upwards, upper width is greater than the groove body type structure of lower width, said two hang plates, 301 top edges are fixedly connected on the inwall of heat radiation aluminum pipe 1; Two hang plates 301 are respectively 120 ° ,-120 with level board 302 angulations; The parallel respectively PCB substrate 4 that is equipped with on said level board 302 and two hang plates 301; Be provided with a slice LED luminescence chip 5 at least in said PCB substrate 4, the concrete needs of how many bases of its mounted LEDs luminescence chip 5 numbers are set.
To sum up, the utility model is through being designed to light source board 3 to have the structure of hang plate 301, and promptly light source board 3 comprises level board 302 and is connected to the hang plate 301 of level board both sides; Be separately installed with a PCB substrate 4 on level board 302 and two hang plates 301, be provided with a slice LED luminescence chip 5 at least, so in said PCB substrate 4; Make the lighting angle of LED fluorescent lamp enlarge; Reduced the dark space of light fixture both sides, further, said two hang plates 301 and level board institute 302 are angled to be respectively 120 ° ,-120; By this; Make the lighting angle maximization of LED fluorescent lamp, eliminated the dark space of light fixture both sides, the illumination effect of this LED fluorescent lamp is more near the illumination effect of fluorescent lamp; In addition, it is simple in structure, is convenient to produce in batches, and is practical.
