Abstract

The utility model provides a light-emitting diode (LED) daylight lamp, which relates to a daylight lamp structure which adopts LEDs as a light source and comprises a body, a lamp cover, two lamp holder covers, a reflecting strip and a circuit board. Two ends of the body are provided with first clamping parts, two ends of the lamp cover are provided with second clamping parts, and the body and end portions of the lamp cover are wrapped and fixed by the two lamp holder covers. The bottom surface of the circuit board is fixed on the surface of the body facing the direction of the lamp cover, two ends of the circuit board are respectively in electric connection with electrodes fixed on the two lamp holder covers, a vertex angle is formed on the surface of the circuit board, and the reflecting strip is arranged at the position of the vertex angle. Surfaces of the circuit board arranged on two sides of the reflecting strip are respectively connected with LED chips, the LED luminous chips arranged on the two sides light at a certain angle, thereby resolving the problems that traditional light sources are emitted from the same direction and light illumination angles are small. Moreover, the LED luminous chips on the circuit board are all arranged along the length direction of the circuit board in staggered mode, thereby enabling light emitted by the LED luminous chips to be more even and greatly reducing light spot feeling, namely the problems of point light source and glare.

Description

A kind of LED fluorescent lamp

Technical field

The utility model belongs to lighting field, and particularly a kind of LED of employing is the fluorescent structure of light source.

Background technology

Higher luminous efficiency, low radiation, low power consumption, life-span length, low driving voltage, startup are quick because LED has, environmental protection, antidetonation resistance to compression, advantages such as light fixture Miniaturizable, therefore LED is progressively substituting existing all lighting sources, traditional fluorescent type fluorescent lamp is because its popularity becomes the important object that LED substitutes, therefore, each LED fluorescent lamp arises at the historic moment.

Yet existing LED fluorescent lamp is made up of cylindrical Transparent lamp tube and the led light source substrate that is installed in the fluorescent tube usually.In order to improve the irradiance of LED fluorescent lamp; the LED luminescence chip of multiple row is installed on the led light source substrate; but all LED luminescence chips are all to same direction irradiation; make the light angle deficiency of LED fluorescent lamp; the patent No. is 201010186113.7 to have proposed a kind of fluorescent structure; because its LED lamp shines to both sides; can produce effect middle and both sides light inequality; afterwards in order to increase illumination angle; adopt the light scattering that increases lampshade; usually can in the material of making lampshade, add the light scattering that diffusion particle increases lampshade, though it is this kind mode can increase the effect of light scattering, not obvious to the effect that promotes light angle.In addition since LED(its be low-power LED) the hot spot sense that certainly led to of discrete type light characteristics be spot light, glare problem, the designer who is all LED fluorescent lamps can face and the necessary technical barrier that solves by every means, because it makes the LED fluorescent lamp make the people uncomfortable, even can serious degree to the eyes that damage the people.And existing two kinds of ways: the one, come finding method from LED itself, abandon excellent performance, straw hat type white light LEDs cheap, easy to process, adopt cost an arm and a leg, the New LED of processed complex, make the higher LED fluorescent lamp selling price of original selling price higher.The 2nd, seek the method that solves from Transparent lamp shade, scheme is a lot, but all escapes not open a relation that is difficult to go beyond, promptly be that sense solves well more to hot spot, the loss of its illuminance is also big more, therefore, to guarantee illuminance with additive method simultaneously, same, must cause the rising of cost.

Summary of the invention

This novel purpose is to overcome above-mentioned the deficiencies in the prior art part and a kind of and traditional fluorescent lamp structural similarity are provided and have the good illumination angle and can reduce the LED fluorescent lamp of hot spot sense significantly.

This novel can being achieved through the following technical solutions: a kind of LED fluorescent lamp, comprise that two ends have lamp holder lid, a reflection bar and circuit board that the body of first holding section, two ends have the lampshade of second holding section, two be coated and fixed body and lampshade ends, the bottom surface of circuit board is fixed in towards lampshade one side's body surface, the circuit board two ends respectively be fixed on the electrode that two lamp holders cover and be electrically connected, the surface of circuit board forms a drift angle, described reflection bar places the drift angle place, and the surface of the circuit board of reflection bar both sides is connected to led chip respectively.

Described led chip is arranged along the circuit board length direction, the interlaced arrangement of the led chip of reflection bar both sides.

Described body is a metal material, and described lampshade is the plastic cement pipe of printing opacity, and metal body and lampshade are by first holding section and second holding section setting-in that fastens.

But described circuit board is the back side viscosity circuit board of insulating heat-conductive glue is arranged, and circuit board is pasted on body internal surface.

Described circuit board can be a whole piece, and the middle part is bent to form described drift angle to the lampshade direction, and this moment, described reflection bar was fixed in the bending place of circuit board surface.

Described circuit board also can be separately two, and the both sides that lay respectively at reflection bar form described drift angle, and this moment, described reflection bar was fixed in body.

This novel beneficial effect is: the inner surface that 1, circuit board is individually fixed at an angle LED fluorescent lamp body, LED luminescence chip on the circuit board of both sides is simultaneously luminous at an angle, can break through traditional light source sends from same direction, the problem that irradiation angle is little increases the irradiating angle of light source greatly; 2, the LED luminescence chip on the circuit board all is staggered mode and arranges along the direction of circuit board length, the light that the LED luminescence chip is sent is more even, add in the centre of two circuit boards and also be embedded with a reflecting part, the a part of light that can simultaneously both sides LED luminescence chip be sent reflects away by reflecting part, can make light more even soft, be the problem of spot light, dazzle thereby significantly reduced the hot spot sense; 3, can guarantee the illumination of light under the situation that does not change led chip and lampshade material, its cost and with low cost more adapts to the trend that existing LED fluorescent lamp develops.
