Angle-adjustable LED energy-saving lamp device

Abstract

The invention discloses an angle-adjustable LED energy-saving lamp device which comprises a lamp cover. An upper cover plate is fixed at the top of the lamp cover, a middle partition is fixed in the lamp cover, an adjusting through groove is formed in the middle of the middle partition, an arc-shaped shell is inserted in the adjusting through groove in a sleeving manner, an arc-shaped wall face of the arc-shaped shell downward extends out of the adjusting through groove, two side walls of the top of the arc-shaped shell are provided with extension sides radially extending outward, a hinging block is arranged in the middle of the top face of each extension side, an adjusting stub is hinged on each hinging block, an adjusting column is connected at the top of each adjusting stub in a threaded manner and hinged on a supporting plate fixed on the inner side wall of the top of the lamp cover through a bearing, a rotating shaft is arranged at the upper end of each adjusting column, and a rotating gear is fixed on each rotating shaft. Irradiation angle of LED lamps can be adjusted to meet different irradiation requirements; the LED lamps with warm-color light sources and cold-color light sources are arranged on the device, so that irradiation effect of different LED lamps can be adjusted according to different using requirements.

Description

Technical field: [0001] The invention relates to the technical field of energy-saving lamps, in particular to an angle-adjustable LED energy-saving lamp device. Background technique: [0002] LED is a semiconductor light-emitting diode. LED energy-saving lamps use high-brightness white light-emitting diodes as light sources. They have high light efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection. They are a new generation of solid cold light sources. Energy-saving lamps are energy-saving, high brightness, long-distance light projection, good light-emitting performance, and wide voltage range. The light source can realize seven color changes of LED through the built-in microcomputer controller. The light color is soft, bright, colorful, low loss, and low energy consumption. Low energy consumption, green and environmental protection, suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels...

AI Technical Summary

Problems solved by technology

Compared with incandescent lamps or low-voltage fluorescent lamps, the stability and long life of LEDs are obvious advantages. However, the existing LED lamps have warm or cool color light, and their color temperature cannot be adjusted according to the needs of different users.

[0003] However, the existing LED light source is generally directed downward, which strengthens the light in the middle of the lamp, making it difficult for some users to adapt, and the irradiation angle of the LED light source cannot be adjusted.
