Abstract
The utility model relates to an oval light emitting diode (LED) tube lamp. A tube lamp support is made of metallic material; cross section of the tube lamp support is in a half oval shape; a plurality of tooth-shaped strips are horizontally and symmetrically arranged on the outer circle surface on two ends of the tube lamp support; a T-shaped slot is arranged in the surface of the tube lamp support; two surfaces connected with two ends of the T-shaped slot are inclined surfaces; symmetrical lamp shade clamping slots are arranged on the joints of the two inclined surfaces and half oval profiles; symmetrical two open studs are arranged on a cavity; heat conducting silicon strips are adhered in the T-shaped slot of the tube lamp; two sets of strip type printed circuit boards (PCB) horizontally embedded into the heat conducting silicon strips in the T-shaped slot in an abutting joint mode and in series; a constant current source block is arranged in the cavity of the tube lamp support and connected with the PCBs; a tube lampshade is connected on the lampshade clamping slots of the tube lamp support; two tube lamp end sockets are respectively fixed on the tube lampshade and two ends of the tube lamp support. The oval LED tube lamp has the advantages of being capable of saving electricity more than 60 percents than a common fluorescent lamp tube and saving energy more than 20 percents than a T8 LED tube lamp, possessing service life of 50 kh, generating on pollution, and being free of pollution elements such as lead and hydrargyrum.
Description
Technical field
The utility model relates to a kind of oval LED spot, is widely used in the illuminations such as family, hotel, shop.
Background technology
There are following defective technically in existing conventional fluorescent lamps and LED spot:
1. luminous intensity distribution: it is luminous that fluorescent lamp belongs to circumference, and luminous energy can not 100% be employed.T8LED fluorescent lamp section bar surface of light source and light output surface distance are short.The light surface uniformity is poor, and light emission rate is low.
2. thermal diffusivity: fluorescent lamp belongs to gas discharge, causes the light fixture heating, adds the ballast heating, and gross calorific power is high.The T8LED fluorescent lamp section bar area of dissipation snapshot of oneself rings light fixture service life.
3, structural: T8LED fluorescent lamp section bar exists that the built-in power space is little is unfavorable for the light fixture assembling
4. Luminaire efficiency: the Luminaire efficiency of fluorescent lamp is low, is unfavorable for energy-conservation.
5. light pollution: fluorescent lamp exists infrared ray, ultraviolet radiation, can cause the aging of light fixture.
6. service life: fluorescent tube is approximately 8000h service life.
7. maintenance cost: fluorescent light need to be changed, and lamp surface needs cleaning.
8. pollute: the pollution elements such as leaded, mercury.
Therefore, demand a kind of novel household illumination spot urgently and substitute conventional fluorescent fluorescent tube and T8LED fluorescent tube.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of oval LED spot, and this spot light emission rate is high, heat conductivility is good, the life-span is long.
the utility model for achieving the above object, the technical scheme that adopts is: a kind of oval LED spot, it is characterized in that: comprise lamp bracket, be welded with the strip pcb board of LED lamp pearl, the constant-current supply piece, the spot termination, the spot lampshade, the thermal conductive silicon adhesive tape, screw, described spot frame adopts shape, its cross section is half elliptic, level symmetrical on the periphery of half elliptic section bar two ends is provided with several dentation bars, be provided with a T-slot on the plane of half elliptic section bar, two faces that are connected with T-slot two ends are the inclined-plane, the connecting place of two inclined-planes and half elliptic section bar is symmetrical lampshade draw-in groove, be provided with two symmetrical opening double-screw bolts in the cavity of half elliptic section bar, described thermal conductive silicon adhesive tape is pasted in the T-slot of spot frame, on two groups of described strip pcb board level docking thermal conductive silicon adhesive tape that are embedded in T-slot in parallel, described constant-current supply piece is arranged in the cavity of spot frame and is connected with pcb board, described spot lampshade is connected on the lampshade draw-in groove of lamp bracket, two spot terminations are plugged on respectively on two ends of spot lampshade and lamp bracket, several screws by the spot termination respectively with cavity in two opening double-screw bolts being provided be spirally connected.
Characteristics of the present utility model are: energy-conservation, utilize light, electricity, look tester to measure oval LED fluorescent tube optics, electrical parameter, and test result and conventional fluorescent lamps pipe, T8LED spot are compared, the power of the oval spot of LED is about 20W, the emergent light flux is up to 1800lm, and light efficiency is greater than 90lm/W; The power of T8LED spot is 20w, emergent light flux 1500lm, light efficiency 75lm/W, the power of conventional fluorescent lamps pipe is about 36W, and the emergent light flux is 1800lm, and light efficiency is 55lm/W, can find out, the oval spot of LED can than conventional fluorescent lamps tube coupling electricity more than 60% than T8LED spot energy-conservation 20%; Life-span is long, and be 50kh service life; Pollution-free: the pollution element such as not leaded, mercury.Can directly use the 220V ac power supply owing to using, therefore can extensive use.
