Abstract
The utility model discloses an LED (light emitting diode) lamp which comprises a housing, a circuit board and LEDs, wherein the circuit board is mounted in the housing in a sealing manner; the LEDs are welded on the circuit board; the LED lamp is characterized in that an optical lens having diffuse reflection and refraction effects is arranged on the housing; the optical lens consists of prismatic lens units; and reflection edges are arranged on the lens units. The LED lamp has the characteristics of reasonable structural design, small dazzle, uniform brightness, low cost and the like.
Description
Technical field
The utility model relates to a kind of LED lamp.
Background technology
The LED light emitting diode has directionality, and center brightness is higher, very easily produces dazzle, and human eye is produced harm.Common led light source generally adopts the additional translucent lampshade to reach the purpose of anti-dazzle, but translucent lampshade has produced larger impact to the luminous flux output of led light source, has also increased the production cost of led light source.For some light sources that can directly adopt transparent encapsulation material, the light-emitting surface brightness of whole light source is even not, and the bottom of LED light emitting diode can produce circular shade, affects the effect of whole light source.On the light fixture of some special-purposes, such as wall lamp and Projecting Lamp etc., the difference of brightness can cause being produced inhomogeneous situation on the metope of light projector.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of low-cost luminous uniform LED lamp that has when reducing dazzle is provided.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this LED lamp, comprise shell, circuit board, LED light emitting diode, circuit board package is welded with light emitting diode in the enclosure on the circuit board, it is characterized in that having on the shell optical lens of diffuse reflection and refraction effect.
Optical lens described in the utility model is made of prismatic lens unit.
Be provided with the reflection limit on the lens unit described in the utility model.
Optical lens described in the utility model and shell one consist of.
The utlity model has the characteristics such as reasonable in design, dazzle is little, brightness is even, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the schematic perspective view of the utility model embodiment.
Fig. 3 is the local enlarged diagram of optical lens shown in Figure 2.
The specific embodiment
Referring to Fig. 1～Fig. 3, the utility model embodiment LED lamp is provided with shell 1, circuit board 2, LED light emitting diode 3, circuit board 2 is installed in the shell 1, is welded with light emitting diode 3 on the circuit board 2, and its design feature is the optical lens 4 that has diffuse reflection and refraction effect on the shell 1.
The described optical lens 4 of present embodiment adopts modification blend engineering plastics one to consist of with shell 1.
Present embodiment adopts the shell 1 and the integrated LED lamp of light source with optical lens 4, by designing the optical lens 4 with diffuse reflection and refraction effect with the integrated shell 1 of light source, the light that LED light emitting diode 3 is sent carries out diffuse reflection and refraction by optical lens 4, can reach the uniform purpose of light-emitting surface brightness of whole light source, diffuse reflection by optical lens 4 and refraction can be eliminated the dark space of LED light emitting diode 3 bottoms, the whole structure of light source is promoted, can effectively reduce the injury that dazzle causes human eye.Adopt with the integrated structure of shell in addition and can reduce production costs, improve the uniformity of product.
The described optical lens 4 of present embodiment is made of several prismatic lens units 5, is provided with the reflection limit 6 of diffuse reflection and refraction on the lens unit 5, and the effect of diffuse reflection and refraction is improved on the reflection limit 6 of scioptics unit 5.
The simple deformation of the utility model technical characterictic or technical scheme and combination should be thought to fall into protection domain of the present utility model.
Claims (4)
