Embodiment Construction

[0026] As shown in FIG. 1 , the LED lighting lamp of the present invention includes a housing 1 , a circuit board 2 , a plurality of LED light sources 3 , a transparent cover 4 , an AC / DC constant current drive power supply 5 , and a plurality of reflector cups 6 .

[0027] Wherein, the shell 1 is formed by one-time die-casting of aluminum alloy, and the back shell 11 of the shell 1 has a heat sink 12 . The shell 1 is made of aluminum alloy, because aluminum alloy is an excellent heat conductor, which can quickly conduct heat generated in the shell 1, and a heat sink 12 is set on the back shell plate 11 of the shell 1, which not only increases the heat dissipation of the back of the shell. The heat dissipation surface area also causes a temperature difference between the inner and outer distances, so that the heat in the shell 1 can be dissipated more quickly.

[0028] The circuit substrate 2 adopts an aluminum substrate 21 , and the aluminum substrate 21 is directly attached ...

Abstract

The invention relates to an LED jacklight, comprising a crust, a circuit substrate arranged inside the crust, a plurality of LED light sources distributed and fixed on the circuit substrate, a diffuser arranged at the crust opening and an AC/DC constant current drive power supply arranged on the crust back. The invention is characterized in that a plurality of reflection cups are arranged on the circuit substrate, corresponding to a plurality of LED light sources; each LED light source is positioned in one reflection cup. The LED jacklight has the advantages that the distribution range of light is wide, the illumination distance is long, the brightness is high and even, the thermal resistance of the LED light sources is lower than the threshold temperature, the attenuation of light intensity is little and the service life is long.

Description

technical field [0001] The invention relates to an illuminating lamp, in particular to an LED illuminating lamp with high power. Background technique [0002] LED (Light-Emitting-Diode, Chinese means light-emitting diode) is a semiconductor that can convert electrical energy into visible light. LED lighting is an emerging industry developed in recent years. It can be called another lighting revolution since the advent of incandescent lamps in the 19th century. The third generation of lighting source after sodium lamp, etc.). It changes the principle of traditional incandescent lamp tungsten light emission and energy-saving lamp three-color phosphor light emission principle, and uses electric field to emit light at room temperature and low voltage. Compared with traditional lighting sources, LED lighting has a series of advantages such as high efficiency, energy saving, environmental protection, and long life, especially in terms of energy saving and environmental protectio...
