Description
Technical Field
The invention relates to the technical field of illumination, in particular to an LED lamp.
Background
The existing LED lamp generally comprises a chassis, a substrate, an LED light source, a power supply and a lampshade. At present, the power supply of the lamp is divided into an isolated power supply and a non-isolated power supply, wherein the non-isolated power supply is divided into a switching power supply and a linear power supply. The isolated power supply and the non-isolated switching power supply are used for reducing the voltage of 120V/220VAC to lower voltage by using a transformer and then rectifying the voltage into direct current output for power supply. The primary winding of the transformer is subjected to 120V/220VAC, the secondary winding is only subjected to the output ac voltage, and the primary and secondary windings are not directly connected, so called an isolated power supply. The conversion process of the transformer is as follows: the electric-magnetic-electric connection is not connected with the ground, so that the electric shock hazard does not occur. The non-isolated linear power supply is directly input into an electronic circuit by 120V/220VAC, and is boosted by an electronic element to output, and the input and the output are directly connected by the electronic element. According to the safety requirement, a 5VA power supply box is required to be arranged outside the power supply.
The isolated power supply has larger volume, more components and higher cost than the non-isolated power supply. The non-isolated electrical switching power supply is more costly than the linear power supply, and the opto-electronic integrated scheme in the linear power supply is the lowest cost.
If the lamp with the isolated power supply is adopted, a lens is not required to be arranged outside the LED light source, light emitted by the LED light source is directly emitted out through the lampshade, the arrangement of the LED light source is dispersed, the area of the lamp panel is large, and the material cost is high. Secondly, the isolation power supply outputs low voltage, and the LED light source generally adopts 3V lamp beads, so that the required lamp beads are more in quantity and higher in cost.
If the lamp with the non-isolated power supply is adopted, a lens is required to be arranged outside the LED light source so as to prevent electric leakage. It should be noted that, due to the lens, the LED light sources can be concentrated, the number is relatively small, and the cost is much lower than that of the lamp with the isolated power source. But the lens is used for diffusing light mainly by refracting light, and part of the light can be refracted to the chassis, so that the light-emitting efficiency of the lamp is reduced. Secondly, in order to meet the safety requirements, the transparent glass is made of polycarbonate with a fire rating of 5AV, and the thickness is more than 2 mm. Since many flame retardants are added to the lens and the thickness is relatively thick, the transmittance of the lens is low, and thus the number of LED light sources needs to be increased.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent.
Referring to fig. 1 and 2, the LED lamp provided by the invention comprises a chassis 1, a power supply 2, a lampshade 3, a substrate 4, an LED light source 5 and a bulb 6, wherein the substrate 4 is fixed on the chassis 1, the LED light source 5 is arranged on the substrate 4, the power supply 2 is electrically connected with the LED light source 5, the bulb 6 covers the LED light source 5, light emitted by the LED light source 5 is sequentially emitted through the bulb 6 and the lampshade 3, the bulb 6 is made of polycarbonate, and the thickness of the bulb 6 is 0.75-1.75mm.
According to the invention, the bulb shell 6 is covered on the LED light source 5, and the light emitted by the LED light source 5 is firstly diffused through the bulb shell 6, so that the light emitting angle of the LED light source 5 is increased, the light emitted by the bulb shell 6 finally emits light through the lampshade 3, and the light emitting angle of the LED light source is finally increased, so that the light emitted by the lamp is more uniform. In addition, the bulb shell 6 can also protect the LED light source 5, so that the LED light source 5 is prevented from generating electric leakage, and the safety requirement of the lamp is met.
It should be noted that, since the bulb 6 of the present invention is made of Polycarbonate (PC), the thickness of the bulb 6 of the present invention can be greatly reduced compared to a lens, and at the same time, the light transmittance of the bulb 6 can be greatly improved, and preferably, the thickness of the bulb is 0.75-1.75mm. If the thickness of the bulb shell is smaller than 0.75mm, the flame retardant grade is insufficient, and the safety requirement is not met; if the thickness of the bulb shell is larger than 1.75mm, the material cost is high, and the light transmittance is low. More preferably, the thickness of the bulb shell is 0.9-1.2mm. In order to ensure that the lamp meets safety requirements, the bulb 6 is preferably made of polycarbonate with a flame retardant grade V0.
Specifically, a certain amount of light diffusing agent needs to be added to the polycarbonate material from which the bulb 6 is made, wherein the more the light diffusing agent is, the more uniform the light is, but the light transmittance is correspondingly reduced. The invention makes the light emitting uniformity of the lamp meet the requirement by reasonably designing the structure of the lamp, so the invention only needs to limit the light transmittance of the bulb shell, and the light transmittance of the bulb shell is preferably more than 90 percent.
Further, compared with the lens, the bulb shell is made of Polycarbonate (PC), and the material cost and the production cost can be greatly reduced.
The bulb shell 6 is covered on the LED light sources 5, so that the light emitting angle of the LED light sources 5 can be increased, and the LED light sources 5 can be intensively arranged on the substrate 4, so that the number of the LED light sources 5 and the area of the substrate 4 are reduced. In addition, the light transmittance of the bulb shell is obviously higher than that of the lens, so that the number of the lamp beads of the LED light source 5 can be further reduced. The number of the lamp beads of the LED light source 5 can be reduced by 8% -15% by lamps with the same size and the same brightness.
In order to match the bulb shell to emit light, the material of the lampshade 3 is glass, polymethyl methacrylate, polycarbonate, polystyrene, polymer of methyl methacrylate and styrene.
The shape of the bulb 6 matches the arrangement shape of the LED light sources 5. In particular, the bulb 6 is hemispherical, cylindrical or cubic in shape, but is not limited thereto. Preferably, the bulb 6 is hemispherical in shape.
Referring to fig. 3, the thickness of the top of the bulb 6 is greater than the thickness of the sidewall, so that the light emitted onto the lamp cover 3 can be relatively uniform. Since the material of the bulb 6 of the present invention is polycarbonate, the thickness of the top of the bulb 6 may be greater than the thickness of the side walls. Preferably, the thickness of the top of the bulb 6 is 0.3-1mm greater than the thickness of the side walls. If the thickness difference between the top of the bulb shell 6 and the side wall is smaller than 0.3mm, the thickness of the top of the bulb shell is too small, and finally the emergent light is concentrated at the top of the lamp; if the thickness difference between the top and the side wall of the bulb shell 6 is larger than 1mm, the thickness of the top of the bulb shell is too large, and the light transmittance of the bulb shell is reduced.
Specifically, referring to fig. 4 to 6, fig. 4 is a graph showing the effect of light emission from a lamp when the thickness of the top of the bulb is 0.3mm greater than the thickness of the side wall; FIG. 5 is a graph of the light emitting effect of the luminaire when the thickness of the top of the bulb is 0.6mm greater than the thickness of the side wall; fig. 6 is a graph of the light emitting effect of the lamp when the thickness of the top of the bulb is 1mm greater than the thickness of the side wall.
Referring to fig. 7, the ratio of the width (D) of the bulb to the width (D) of the lamp housing, and the distance (H) from the top of the bulb to the top of the lamp housing, have an important effect on the overall light uniformity of the lamp. Specifically, the ratio of the width (D) of the bulb shell to the width (D) of the lampshade is 1: (2-5). The distance (H) from the top of the bulb shell to the top of the lampshade is more than or equal to 40mm. If the ratio of the width (D) of the bulb to the width (D) of the lamp shade is less than 1:5, the light pattern is too concentrated, and the edge of the lampshade has a very obvious dark area; if the ratio of the width (D) of the bulb to the width (D) of the lamp shade is greater than 1:2, the bulb shell area is too large, and the material cost is high.
In addition, if the distance (H) from the top of the bulb shell to the top of the lampshade is smaller than 40mm, the distance between the bulb shell and the lampshade is too small, and light is concentrated at the top of the lampshade to emit light, so that the light emitted by the lamp is uneven, the middle is bright, and the edge is dark. Specifically, referring to fig. 8 to 10, fig. 8 is a schematic light emitting diagram of the lamp when the distance (H) from the top of the bulb to the top of the lamp cover is 40 mm; FIG. 9 is a schematic view of the luminaire light emission with a 60mm distance (H) from the top of the bulb to the top of the lamp housing; fig. 10 is a schematic view of the light output of the lamp when the distance (H) from the top of the bulb to the top of the lamp cover is 80 mm.
The power supply 2 of the present invention is a non-isolated power supply. Preferably, the power supply 2 is a non-isolated linear power supply. The bulb shell 6 is covered on the LED light source 5 to prevent electric leakage, so that the cost is reduced. The power supply 2 may be disposed inside the bulb 6 or outside the bulb 6. If the power supply 2 is arranged in the bulb shell 6, the power supply 2 and the LED light source 5 can be preset on the substrate 4 in advance, so that photoelectric integration is realized, automatic installation is convenient, labor cost is reduced, and production automation is facilitated.
It should be noted that the lamp of the present invention is a ceiling lamp, but is not limited thereto. The lampshade 3 is connected to the chassis 1 to form a containing cavity; the base plate 4 is fixed on the chassis 1 through a fixing piece, wherein the power supply 2, the base plate 4, the LED light source 5 and the bulb shell 6 are all arranged in the accommodating cavity.
The outward flange of lamp shade 3 is equipped with draw-in groove 31, the inside wall of chassis 1 is equipped with the screens arch, lamp shade 3 can be through rotatory with the protruding card of screens in draw-in groove 31 to install lamp shade 3 on chassis 1.
The above disclosure is only a preferred embodiment of the present invention, and it is needless to say that the scope of the invention is not limited thereto, and therefore, the equivalent changes according to the claims of the present invention still fall within the scope of the present invention.
