Back lighting type LED environment lamp

Abstract

The invention discloses a back lighting type LED environment lamp which comprises a support, a lampshade, a power source, a circuit board, an LED and a lens. The lampshade is arranged on the support, the circuit board is arranged in the lampshade, the power source is arranged on the circuit board, the LED is arranged in front of the circuit board, and the lens is arranged in front of the lampshade. According to the mode, the back lighting type LED environment lamp has the advantages of being high in reliability, compact in structure, changeable in color, low in cost, adjustable in lighting direction, capable of utilizing the wall light dissipation, good in lighting effect, good in heat dissipation, low in energy consumption, long in service life and the like, and meanwhile the lamp has the wide market prospect in the environment lighting field.

Description

Technical field [0001] The invention relates to the field of CNC machine tool holders, in particular to a back-illuminated LED environmental light. Background technique [0002] LED, or light-emitting diode, is a new type of light source with low power consumption, long life, small size, high brightness, low energy consumption, and no pollution. It is known as the green lighting source of the 21st century, but it is limited by the light-emitting principle of LED It cannot have good astigmatism characteristics like ordinary incandescent lamps and fluorescent lamps. It often has problems such as small illumination range, large difference in brightness between irradiated and non-irradiated areas. At the same time, due to the small size of the luminous body, the heat is concentrated, and the package heat dissipation is not good. , Which often causes the LED junction temperature to be too high, leading to serious light decay and affecting the service life. Summary of the invention [...
