Abstract

The utility model provides a light-emitting diode (LED) daylight lamp capable of illuminating on two sides. The LED daylight lamp capable of illuminating on the two sides comprises a lamp tube and lamp holders, wherein the lamp holders are arranged on two ends of the lamp tube and provided with power source pins. The lamp tube comprises a lamp cover and a baseplate, and the lamp cover and the baseplate are buckled vertically. The length of the lamp cover and the baseplate is equal to that of the lamp tube. The baseplate comprises arc faces which are connected with each other and a luminous face which is used to fix the LED baseplate, the arc faces form a portion of an outer wall of the lamp tube, the luminous face is arranged inside the lamp tube, and a protruded separating plate is arranged in the middle of the luminous face. The separating plate penetrates through the whole length of the luminous face and divides the luminous face into two portions which are symmetrical left and right, a connection portion of the two portions hunches up, and an included angle of the two portions is less than 180 degrees. Each portion is respectively provided with an LED baseplate, furthermore, the included angle of the two portions is 160 degrees, and therefore an illuminating angle is increased to be 140 degrees. Due to the fact that a portion of a section bar for placement of a printed circuit board (PCB) is arranged into tow pieces through the luminous face, the luminous face of a polycarbonate (PC) cover is increased after the lamp tube is switched on, no dark space exists, and the LED daylight lamp capable of illuminating on the two sides can bring delightful feelings for people.

The LED fluorescent lamp that exists on the market at present, all be that a plane that is used for placing the PCB circuit board is set in lampshade, the circuit board that is covered with LED is placed on this plane, such LED fluorescent lamp, light-emitting area only has one, lighting angle is less, has all limited further applying of LED fluorescent tube.
The utility model content
The utility model namely is the defective that light-emitting area is single, lighting angle is little that exists in LED fluorescent lamp field at present, designs and produces a kind of two light-emitting areas that have, can the luminous LED fluorescent lamp of wide-angle.
Specifically, but lighting at two sides LED fluorescent lamp described in the utility model, comprise fluorescent tube and the lamp holder that is positioned at lamp tube ends, has power pin on the lamp holder, fluorescent tube comprises lampshade and the substrate that fastens up and down, the length of lampshade and substrate all with the equal in length of fluorescent tube, substrate comprises interconnected arc surface and is used for the light-emitting area of fixed L ED substrate, arc surface consists of the part of tube outer wall, light-emitting area is positioned at fluorescent tube, the middle part of light-emitting area is provided with the demarcation strip of projection, demarcation strip runs through the total length of light-emitting area, and light-emitting area is separated into symmetrical two parts, and the part that two parts link to each other arches upward upward, two-part angle arranges respectively the LED substrate less than 180 ° on every part.
But described lighting at two sides LED fluorescent lamp is characterized in that: described two-part angle is 160 °, is 140 ° thereby increased lighting angle.
But described lighting at two sides LED fluorescent lamp is characterized in that: the mutual clamping of described lamp holder and fluorescent tube.
But described lighting at two sides LED fluorescent lamp is characterized in that: two edges of described lampshade have respectively the fin that protrudes to the inside, and the both sides of substrate have corresponding groove, and fin snaps in the groove, realize the tight fit of lampshade and substrate.
But described lighting at two sides LED fluorescent lamp is characterized in that: the material of described lampshade is PC.
PC is Merlon (Po1ycarbonate), is a kind of water white indefiniteness thermoplastic.Merlon water white transparency, heat-resisting, shock resistance, fire-retardant have good mechanical performance in common serviceability temperature.Compare near polymethyl methacrylate with performance, the impact resistance of Merlon is good, and refractive index is high, and good processability does not need additive just to have UL94V-0 level fire resistance.
But described lighting at two sides LED fluorescent lamp is characterized in that: the material of described lamp holder is plastic cement.
But described lighting at two sides LED fluorescent lamp, it is characterized in that: the material of described substrate is aluminum or aluminum alloy, has better radiating effect.
But described lighting at two sides LED fluorescent lamp is characterized in that: the outer surface of described substrate have a plurality of parallel to each other and with the rib groove of substrate equal in length, increased area of dissipation.
But lighting at two sides LED fluorescent lamp described in the utility model makes two into by light-emitting area is partly put the pcb board place with section bar, and the section bar angle makes 160 degree into, thereby increased lighting angle and be 140 degree, PC cover light-emitting area increases behind the lamp tube starting, does not have the dark space, and visual effect people is pleasing.
