Abstract

The utility model relates to the field of lighting lamps, in particular to an LED lamp. The LED lamp comprises a lamp holder, an aluminum lamp shell, a metal mounting ring, LED chips and a lens, wherein the lamp holder is fixedly connected with the aluminum lamp shell; the LED chips are fixed on a circuit board in the aluminum lamp shell; the section of the metal mounting ring is L-shaped; the metal mounting ring is in threaded connection with the outer side wall of the aluminum lamp shell; the lens is mounted on the aluminum lamp shell through the metal mounting ring; chip cavities are arranged on the top of the lens, and the positions and the quantities of the chip cavities correspond to those of the LED chips; and the bottoms of the LED chips extend in the chip cavities. The LED lamp has the advantages that the LED lamp is good in radiating effect and long in service life, the lens is mounted firmly, and accordingly the LED lamp is widely applicable to the industry of lighting lamps.

Description

The LED light fixture

Technical field

The utility model relates to field of illuminating lamps.

Background technology

The LED light fixture is because green energy conservation is used widely.The structure of LED light fixture is identical mostly; Comprise lamp holder, lamp housing, led chip, wiring board, driver and lens; Lamp holder is connected with lamp housing, and lens are installed on the lamp housing, and led chip is installed and is connected with lamp holder in the circuit board and through 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 pass through glue on lamp housing, the too high situation of coming unstuck that is easy to generate of temperature during use.

Summary of the invention

The goal of the invention of the 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.

In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:

The LED light fixture; Comprise lamp holder, aluminum lamp housing, metal installing ring, led chip and lens; Lamp holder is fixedly connected with the aluminum lamp housing, and led chip is fixed on the wiring board in the aluminum lamp housing, and metal installing ring cross section is L-shaped; The metal installing ring is threaded with aluminum lamp housing lateral wall, and lens are installed on the aluminum lamp housing through the metal installing ring; The lens top is provided with the chip cavity volume corresponding with led chip position and quantity, and the led chip bottom is stretched in the chip cavity volume.

As preferably, the led chip on the said wiring board is to be square 4 that arrange, and the chip cavity volume is 4 corresponding with led chip of position and quantity.

Adopted the LED light fixture of technique scheme, aluminum lamp housing good heat dissipation effect, lens are installed on the aluminum lamp housing through the metal installing ring, and the led chip bottom is stretched in the chip cavity volume of lens, and lens are fixed and can not be rotated by led chip.The advantage of this LED light fixture is a good heat dissipation effect, long service life, and lens are installed firmly, can be applicable to the lighting industry widely.

Description of drawings

Fig. 1: the structural representation of the utility model embodiment.

The specific embodiment

Do to further describe below in conjunction with 1 pair of the utility model of accompanying drawing, the LED light fixture among Fig. 1 adopts the signal of the latter half broken section.

LED light fixture as shown in Figure 1 comprises lamp holder 1, aluminum lamp housing 2, metal installing ring 5, led chip 3 and lens 6, and lamp holder 1 is fixedly connected with aluminum lamp housing 2, and led chip is fixed on the wiring board 4 in the aluminum lamp housing.Installation of driver in the lamp holder 1, lamp holder 1 is through the led chip on the driver connection line plate 4.Metal installing ring 5 cross sections are L-shaped, and metal installing ring 5 is threaded with aluminum lamp housing 2 lateral walls, and lens 6 are installed on the aluminum lamp housing 2 through metal installing ring 5.Lens 6 tops are provided with and led chip 3 positions and the corresponding chip cavity volume 61 of quantity, and led chip 3 bottoms are stretched in the chip cavity volume 61, and lens 6 are by led chip 3 fixing can not rotations.Led chip 3 on the wiring board 4 is to be square 4 that arrange, chip cavity volume 61 to be position and quantity corresponding with led chip 34.

Claims (2)

1.LED light fixture; Comprise lamp holder, aluminum lamp housing, metal installing ring, led chip and lens; Lamp holder is fixedly connected with the aluminum lamp housing, and led chip is fixed on the wiring board in the aluminum lamp housing, it is characterized in that metal installing ring cross section is L-shaped; The metal installing ring is threaded with aluminum lamp housing lateral wall, and lens are installed on the aluminum lamp housing through the metal installing ring; The lens top is provided with the chip cavity volume corresponding with led chip position and quantity, and the led chip bottom is stretched in the chip cavity volume.
