Description

A kind of LED light fixture

Technical field

The utility model relates to field of illuminating lamps, relates in particular to a kind of LED illuminating lamp.

Background technology

The LED light fixture is because green energy conservation is used widely.The structure of LED lamp is identical mostly, comprise lamp holder, lamp housing, led chip, wiring board, driver and lens, lamp holder is connected with lamp housing, lens are installed on the lamp housing, led chip is installed and is connected with lamp holder in the circuit board and by driver, wiring board is arranged in the lamp housing, the corresponding lens in led chip position.The deficiency that existing LED lamp exists comprises following two kinds, a kind of is that radiating effect is poor, and led chip is overheated to cause service life short, and another kind of lens are connected insecure with lamp housing, for example be bonded on the lamp housing the too high situation of coming unstuck that is easy to generate of temperature during use by glue.

Summary of the invention

Goal of the invention of the present utility model is in order to overcome the deficiency that above-mentioned existing LED light fixture exists, a kind of good heat dissipation effect to be provided, the LED light fixture that the lens installation is firm.

The technical solution of the utility model is:

A kind of LED light fixture comprises lamp holder, lamp housing, led chip and lens, and lamp holder is fixedlyed connected with lamp housing, and lens are installed on the lamp housing, and led chip is arranged in the lamp housing, also comprises installing ring and light cup; The light cup is located in the lamp housing, and the position of led chip is in the light cup; Described lamp housing is the aluminum heat-dissipation lamp housing, and its lateral wall is provided with many regularly arranged aluminum heat radiation spokes; Described lens are convex lens, and the convex lens outer face is connected on the interior ring of installing ring, and inner face props up light cup outer end, and convex lens are fixed on the front end face of aluminum heat-dissipation lamp housing by installing ring.

As preferably, described light cup cross section is the shape of falling M, and place is provided with the through hole that passes for led chip in the middle of it, has strengthened luminous efficiency.

As preferably, described installing ring is installed on the front end face of aluminum heat-dissipation lamp housing by screw, and the screw installation site is in the edge in the installing ring outside, and lens are installed very firm.

As preferably, described LED light fixture also comprises wiring board and driver, and led chip is installed and is connected with lamp holder in the circuit board and by driver, and wiring board is arranged in the lamp housing, and driver is arranged in the lamp holder, and it is the most reasonable that component locations designs.

As preferably, described aluminum heat radiation spoke is at least 8, good heat dissipation effect.

By the LED light fixture of the technical solution of the utility model design, the position of led chip is in the light cup, and lamp housing is the aluminum heat-dissipation lamp housing, and lens are convex lens, and convex lens are fixed on the front end face of aluminum heat-dissipation lamp housing by installing ring and light cup.The advantage of this LED light fixture is the good heat dissipation effect long service life, and it is very firm that lens are installed, and this LED light fixture can be applicable to the lighting industry widely.
