Description

The LED that a kind of light extraction efficiency is high

Technical field

The utility model relates to a kind of LED illumination lamp, espespecially a kind of LED high by a kind of light extraction efficiency of PC reflecting strips raising emitting brightness.

Background technology

LED illumination lamp is generally common in the modern life and the illuminating lamp of practicality, LED is luminous primarily of semi-conducting material conduction, because LED illumination lamp has long service life, power consumption is low, safe and reliable, advantages such as energy-conserving and environment-protective and being widely used, and LED lamp is replaced easily, but, within existing LED illumination lamp is arranged on lampshade, the light-source brightness that the light source of LED illumination lamp irradiates out after through lampshade dies down, and more existing arrange in pairs or groups with LED illumination lamp the fluorescent tube that uses and light-reflecting sheet with make LED illumination lamp brightness insufficient during LED lamp united application because material selection is improper, lamp tube material as adopted is impermeability, its diffusivity is poor, cause light source through brightness step-down after fluorescent tube, the reflectorized material reflecting power difference and for example adopted or poor electric conductivity, light source brightness when reflecting effect is bad is weakened, thus cause light source waste, the light extraction efficiency of visible LED illumination lamp only has its room for promotion of performance, the problem of light source waste could be solved.

Summary of the invention

For solving the problem, the utility model is intended to open a kind of LED illumination lamp, espespecially a kind of LED high by a kind of light extraction efficiency of PC reflecting strips raising emitting brightness.

For achieving the above object, the technical solution adopted in the utility model is: the LED that a kind of light extraction efficiency is high, described LED mainly comprises fluorescent tube, plug, light source and power supply, and plug is arranged on the two ends, left and right of fluorescent tube, and light source is arranged in fluorescent tube by PCB lamp board; It is characterized in that: the light source both sides in described PCB lamp board are all provided with PC reflecting strips; Described plug is rotatable plastic cement plug, and between plug and fluorescent tube, axle sleeve is connected with in plug and connects block, connects the silica gel snare being arranged with outside block junction and connecing block in fixing plug in fluorescent tube and plug.

Described PCB lamp board is fixed in fluorescent tube by aluminium section bar.

Described fluorescent tube is PC light anemostat.

Connect block arranged outside in described plug and have scale, scale is the number of degrees of the plug anglec of rotation.

Offer one piece of little groove outside described plug, in little groove, plug blades is installed.

The beneficial effects of the utility model are embodied in: the utility model adopts PC reflecting strips to act in LED described in the utility model, can reflex LED light source thus improve light-source brightness, adopt PC reflecting strips and the acting in conjunction of PC fluorescent tube simultaneously, because the light transmission of PC fluorescent tube is good, and PC reflecting strips to launch the ability of light strong thus make its light emission rate high, therefore the two compound action, make LED lamplight reflecting power strong, light extraction efficiency is high, illumination dynamics is more efficient more clear, being applied in various occasion can create bright and clear, clear bright lighting environment, good protective effect is had to the glasses of people and eyesight thereof, and the utility model adopts the structure of to fix PCB lamp board with aluminium section bar, make connection more stable, and aluminium section bar corrosion resistance, electric conductivity, recuperability are high, are the materials that a kind of utilization rate is high, the plug adopted is the plastic cement plug of angle rotatable, be convenient to install, and can assembling effect be confirmed by observing plug rotational steps, block skin and the sheathed silica gel ring in fluorescent tube junction is connect in plug and plug, not only water resistance is good, and the dust-proof effect of mildew-resistant also thus promote, and can be applicable to numerous places such as open air, refrigerator-freezer, bathroom.

Detailed description of the invention

Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing:

The LED that a kind of light extraction efficiency is high, described LED mainly comprises fluorescent tube 1, plug 2, light source 3 and power supply 4, and plug 2 is arranged on the two ends, left and right of fluorescent tube 1, and described fluorescent tube 1 is PC light anemostat, the light transmission of PC fluorescent tube is good, can irradiate by diffused light source 3 to large extent; Light source 3 is arranged in fluorescent tube 1 by PCB lamp board 5, and power supply 4 and PCB lamp board 5 are electrically connected, and described PCB lamp board 5 is fixed in fluorescent tube 1 by aluminium section bar 6; Light source 3 both sides in described PCB lamp board 5 are all provided with PC reflecting strips 7, PC reflecting strips 7 can reflex LED light source 3 thus improve light source 3 brightness, makes that LED lamplight reflecting power is strong, light extraction efficiency is high, and illumination dynamics is more efficient more clear; Described plug 2 is rotatable plastic cement plug, between plug 2 and fluorescent tube 1, axle sleeve is connected with in plug and connects block 8, the silica gel snare 9 being arranged with outside block 8 junction and connecing block 8 in fixing plug is connect in fluorescent tube 1 and plug, adopt the connection connecing block 8 in silica gel snare 9 fixed lamp tube 1 and plug, the effects such as protection against the tide, mildew-resistant, dust-proof pollution can be played; Connect block 8 arranged outside in described plug and have scale, scale is the number of degrees of plug 2 anglec of rotation, one piece of little groove is offered outside described plug 2, plug blades 10 is installed in little groove, when plug 2 rotates, plug blades 10 follows rotation, by recording the home position of plug blades 10 and rotating the angle that rear position can read plug 2 rotation, can confirm assembling effect by observing rotational steps.
