The LED light source device is disposed between the tube cover and the heat radiation device. The LED light fixture comprises an aluminum base circuit board and a plurality of LED chips. The LED chips are arranged in a manner of LED light source array on the circuit board. A tube cover shaft extends upwardly and inwardly, forming protruding ribs which press against the aluminum base circuit board of the LED light source device. Through the elastic deformation of the protruding rib, the LED light source device and the heat radiation device are fixed, which facilitates the installation and saves cost of punching holes in a radiator and fixes the aluminum base plate and the radiator. The novel LED light fixture has advantages of having a better quality guarantee and prolonging the service lifetime of the LED light fixture.
Description
Technical field
The utility model relates to lighting device, relates in particular to a kind of LED light fixture.
Background technology
In recent years, based on characteristics such as energy-saving and environmental protection, high efficiency, small size, long-lives, the LED light fixture more and more receives people's favor, and the LED light fixture replaces traditional incandescent lamp and fluorescent lamp to become a kind of main flow mode.
The composition of LED light fixture has lamp tube cover, light source, aluminium base, radiator, power supply etc.Because the characteristic of LED, relatively stricter to the requirement of heat radiation, so the design of radiator structure has very big influence to the performance and life-span of LED fluorescent tube, the fixed form of existing aluminium base and radiator has three kinds.
The one, it is interior fixing that aluminium base inserts the groove of radiator; Aluminium base and radiator cooperates or exists very big gap like this; Just be difficult to be inserted in the groove of radiator,, the heat dissipation of radiator had a greatly reduced quality even between aluminium base and the radiator heat-conducting cream is arranged.
The 2nd, aluminium base and radiator are fixed through screw, and this mode aluminium base and radiator can be fitted preferably, still, want extra some positions, hole of multi-processing on the radiator, have increased cost.
The 3rd, aluminium base and radiator are fixed through sticking heat-conducting glue; With sticking heat conduction elastic mounting aluminium base and radiator; Along with the permanent switch of light fixture, the heat conduction rubber cushion receives thermal shock alternately, can cause the heat conduction rubber cushion to lose efficacy; After adopting the heat conduction rubber cushion simultaneously, the dismounting of aluminium base is very big problem points.
Difficult problems such as therefore present LED fluorescent tube exists radiating effect on radiator structure and in the heat conduction link not good, makes and the assembly technology complicacy, and cost is high, and service life is short.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of good heat dissipation effect, technology is simple and cost is low Novel LED lamp, can effectively prolong the service life of LED light fixture.
The technical scheme that the utility model adopted is: a kind of Novel LED lamp; Comprise lamp tube cover, led light source device and heat abstractor; Lamp tube cover is connected with heat abstractor; Light supply apparatus is located between lamp tube cover and the heat abstractor, and lamp tube cover is axially gone up and inwardly formed prominent rib, and prominent rib is pressed on the led light source device led light source device and heat abstractor are fixed.
Said led light source device comprises aluminium base circuit board and a plurality of led chip, and led chip is arranged in the led light source array on circuit board 21.
Said prominent rib is pressed on the aluminium base circuit board of led light source device, and led light source device and heat abstractor are fixed.
Said heat abstractor comprises upper cover plate and radiator, and upper cover plate axially is located at the side that radiator makes progress along radiator.
Said radiator is the semi-cylindrical shaped of hollow, and the part of upper cover plate and radiator hollow forms host cavity.
Said lamp tube cover adopts the PC material to process, and prominent rib and lamp tube cover are one-body molded.
Said LED light fixture two ends are fixed with contact pin and end cap.
The utility model makes two prominent ribs can be pressed on the aluminium base circuit board through about on the lamp tube cover, respectively increasing a prominent rib when mounted, through the elasticity modification of prominent rib; Fix aluminium base circuit board and radiator; Both be convenient to dismounting, and can have saved the cost that on radiator, punches again, can also fix aluminium base and radiator simultaneously; For the LED light fixture provides better quality assurance, prolonged the service life of LED light fixture.
