Flashlight and desk lamp combination based on LED light distribution

Abstract

The invention discloses a flashlight and desk lamp combination based on LED light distribution, which comprises a lamp tube, a light distribution tube, a flashlight lamp holder, a battery, a fixing plate, an LED light source, a collimating lens, a light distribution reflector, frosted glass, a control switch and a fixing frame. The tail of the light distribution tube is fixedly connected with the top of the lamp tube, the flashlight lamp holder is fixedly connected with the head of the light distribution tube, the fixing plate is arranged in the lamp tube, the battery is positioned between the bottom of the lamp tube and the fixing plate, the LED light source is arranged on the fixing plate, the collimating lens is positioned in front of the LED light source, the light distribution reflector is arranged at the inner upper end of the light distribution tube, the frosted glass is arranged at the lower end of the light distribution tube, the control switch is arranged on the outer wall of the lamp tube and is close to the head of the lamp tube, and the lamp tube is fixed onto the fixing frame and can be detached. The property of a light path is changed by the aid of the light distribution reflector, a flashlight and a desk lamp are integrated in design, and the flashlight and desk lamp combination has the advantages that the flashlight and desk lamp combination is fine in lighting effect, can be used as the flashlight and the desk lamp, is convenient and easy to carry, and has a better light shape as compared with other like products by the aid of the structure which can be taken, used and charged at any time.

Description

technical field [0001] The invention relates to an LED lamp with a reflector light distribution device, in particular to a dual-purpose lamp for desk lamp and flashlight based on LED light distribution. Background technique [0002] In recent years, energy saving and environmental protection, and creating a low-carbon society have become the basic policies of countries all over the world. As a new generation of green lighting sources, LED light sources have shown incomparable excellent characteristics of traditional light sources in terms of energy saving and environmental protection. With the continuous improvement of the luminous efficiency of LED, the application of LED is becoming more and more extensive, showing incomparable advantages in terms of energy saving. LED light sources are also applied to electrical appliances used in daily life such as flashlights and desk lamps. [0003] At present, with the progress of society, people's living standards are improving day ...

Problems solved by technology

But this design has a big flaw. As we all know, flashlights and table lamps have different divergence angles after light distribution. Generally, the divergence angle of desk lamps is larger than that of flashlights. , it will cause the local area to be too bright and the surrounding area to be too dark; if the light emitted by a desk lamp is used as a flashlight, the divergence angle will be too large and the penetration power will not be enough, so it can only illuminate a short distance in front
