Description

Lamp tube type LED lamp

Technical field

The utility model relates to a kind of LED light fixture, specifically is a kind of LED lamp of lamp tube type.

Background technology

LED (light emitting diode) is a kind of new type of solid state light source, and it has advantages such as simple in structure, in light weight, that volume is little, consume energy less, response is fast, anti-seismic performance is good, easy to use, belongs to energy-conservation environmental protection illumination.Under same intensity of illumination, the power consumption of LED light fixture and life-span thereof all obviously are better than incandescent lamp, are a kind of light sources of tool development prospect of 21 century.But because LED adopts semiconductor technology, can not at high temperature work, therefore have the heat dissipation problem of light fixture like incandescent lamp.

At present, the LED light fixture of Xiao Shouing is to install metal heat sink additional in the outside of LED light fixture mostly on the market, and this metal heat sink that adds is exposed to the outside of lamp body mostly, by the appearance cross-ventilation to reach the effect of heat radiation.There is following point mostly in this LED light fixture: 1, little, the bright dipping rate variance of illumination range; 2, LED light fixture volume is bigger, influences overall appearance; 3, there is serious potential safety hazard.The concrete reason that produces the problems referred to above is as follows: 1, according to the increase of LED lamp power, the metal heat sink volume that its outside installs additional is also wanted corresponding increase, and the radiator that promptly adds occupies the most surfaces of LED light fixture and amasss; Make the light emitting source of LED light fixture and the not serious imbalance of ratio between the light emitting source, and then influence the illumination range of LED light fixture, cause the bright dipping rate variance of LED lamp.2, because metal heat sink is installed in the outside of LED light fixture, make the volume of existing LED light fixture bigger, directly influence the overall appearance of light fixture.At present, people are in order to reduce the volume of LED light fixture, and often the power supply conversion electron circuit with the LED light fixture is placed in the inner chamber of radiator, electronic circuit is under the condition of high temperature for a long time, and then influences the service life of electronic component and LED light fixture.3, because metal heat sink exposes, easily contact, therefore have serious potential safety hazard with human body.Have only radiator and lamp power are isolated the purpose that just can reach safe handling; But adopt isolated power supply that the electric energy of LED light fixture is provided, then must cause the loss of electric energy conversion.From the technical development of LED as can be known, energy-efficient ACLED (110V or 220V AC power are rectified into direct current directly to be used for LED without step-down) will be the main flow of LED light fixture, and the safety problem of LED light fixture exposed heat spreader also will become a bottleneck for the ACLED development.

Except the problems referred to above, in order to make lamp holder, the accurate connection of lampshade, the production method of the external radiator of existing LED light fixture is 1, adopt die cast, 2, on tension type basis, carry out turning machine-shaping again, these two kinds of production methods all need higher production cost, and then improve the production cost of LED light fixture.
