The structure of the lamp of the present embodiment will be described in detail below.

The lamp of the present embodiment includes a housing 11, a driving power supply 12, a light source assembly 13, a lens module 14, and at least one optical lampshade 15; the light source assembly 13 includes a plurality of light sources 131; the driving power supply 12, the light source assembly 13 and the lens module 14 are all arranged inside the shell 11; the output end of the driving power supply 12 is connected with the input end of the light source component 13; the light source assembly 13 is connected with the lens module 14, the lens module 14 is positioned above the light source assembly 13, and for each light source, a lens in an optical cavity in the lens module is matched with the light source; each optical lampshade 15 is fixedly connected with the upper end of the shell 11.

For each light source 131, the fact that there is a lens in the optical cavity in the lens module 14 to match with the light source means that for each light source 131, there is a lens in the optical cavity in the lens module 14 to perform an optical design on the light emitted by the light source, and if the lens is a collimating lens, the optical design here is to converge the light emitted by the corresponding light source, and adjust the light-emitting angle of the light emitted by the corresponding light source. Optionally, for each light source 131, there is one lens in the optical cavity in the lens module 14 aligned with that light source.

Optionally, the material of the housing 11 may be glass, in which case, the housing 11 is a glass housing.

The glass shell has good high temperature resistance, and has a wide application range to the light source, namely, the glass shell is suitable for the light source with larger calorific value and is also suitable for the light source with smaller calorific value. In addition, the glass shell also has the advantages of long service life, good water resistance, difficult deformation and the like. Simultaneously, the glass shell has satisfied the user to the demand of traditional shell material.

Alternatively, the material of the housing 11 may be plastic, in which case, the housing 11 is a plastic housing.

In this case, the plastic housing may be made of a high temperature resistant plastic material, such as: reinforced modified polyvinyl chloride alloy, polycarbonate, polymethyl methacrylate, polyvinyl chloride, polystyrene, polyethylene and the like. The plastic shell is suitable for light sources with low heat generation, high luminous efficiency and long service life, such as cold cathode light sources, LED light sources, plasma cold light sources and the like. In addition, the plastic shell has the advantages of being not easy to break, easy to form, easy to color, aging resistant, light in weight, low in price and the like.

The driving power source 12, the light source assembly 13 and the lens module 14 are disposed inside the housing 11.

For the light source assembly 13: the light source included in the light source assembly 13 may be an LED light source.

The LED light source has the following advantages: energy conservation and environmental protection: direct current driving is adopted, the electro-optic power conversion is close to 100%, and the same illumination effect is more than 80% of that of the traditional light source; the service life is long: the service life can reach 6 to 10 ten thousand hours, which is more than 10 times longer than that of the traditional light source; the solid cold light source is packaged by epoxy resin, no loose part exists in the lamp body, and the defects of easy burning, thermal deposition, light decay and the like of filament luminescence do not exist.

For the drive power supply 12: the output end of the driving power supply 12 is connected to the input end of the light source assembly 13, specifically, the output end of the driving power supply 12 is connected to the input end of the light source assembly 13 through a wire, and the driving power supply 12 is used for supplying power to each light source 131 included in the light source assembly. If the light source 131 in the light source module is an LED light source, the driving power supply 12 is required to convert the ac voltage of the power grid into the dc voltage required by the lamp, so as to supply power to each LED light source included in the light source module 12.

For the lens module 14: the lens module 14 is connected to the light source assembly 13, and the lens module 14 is located above the light source assembly 13, specifically, the light source assembly 13 may be connected to the lens module 14 by a snap-fit connection. The optical cavity included in the lens module 14 and the light source 131 included in the light source module 13 need to satisfy the following relationship: for each light source 131, there is one lens 141 within the optical cavity in the lens module 14 that matches the light source 131. That is, each light source 131 has a lens 141 matching with it, and the number of optical cavities in the lens module 14 is greater than or equal to the number of light sources 131 in the light source assembly 13.

The lens module 14 includes a plurality of optical cavities, each optical cavity is provided with a lens 141, and each light source 131 has a lens 141 matched with the light source, so that the light emitted by each light source 131 can be adjusted by the corresponding matched lens to form a light-emitting angle, and the light emitted by the plurality of light sources 131 finally forms a whole, smooth and uniform surface-type light-emitting source after passing through the matched lens.

Because the lens module 14 includes a plurality of optical cavities, each optical cavity is provided with one lens 141, and each light source 131 has one lens 141 matched with the light source, light emitted by each light source 131 can be independently adjusted by the corresponding matched lens, and therefore, by using the lens module 14, the light-emitting angle can be adjusted by using one lens for the plurality of light sources 131, the light-emitting angles of light emitted by the plurality of light sources 131 can be better controlled, and the final light-emitting effect can be improved; meanwhile, each light source 131 is provided with one lens 141 matched with the light source, so that more transmitted light rays are required to share one lens relative to the plurality of light sources 131, and less reflected light rays are required to share one lens relative to the plurality of light sources 131, so that the light intensity loss is small, and further, when the power of the light source is larger, the central light intensity of the lamp is correspondingly higher.

It will be understood by those skilled in the art that the optical properties of the lens module 14 determine the optical properties of the light emitted from the plurality of light sources 131 after passing through the lens module 14, such as: light intensity and light exit angle. Therefore, the optical properties of the lens module 14 can be determined according to practical situations, such as the usage environment of the lamp and the properties of the light source itself.

After the light emitted from each light source 131 included in the light source unit 13 is adjusted by the lens module 14 (with respect to the first optical design of the light emitted from each light source 131), the light emitted from the lens module 14 is projected onto the optical cover 15, and the optical cover 15 scatters the light emitted from the lens module 14 (with respect to the second optical design of the light emitted from each light source 131). Because the light emitted by each light source 131 of the light source assembly 13 passes through the lens module 14, an integral, smooth and uniform surface-type light emitting source can be obtained, and the light emitted by the integral, smooth and uniform surface-type light emitting source is relatively uniform after being scattered by the optical lampshade 15.

Optionally, the number of the optical lamp covers 15 is one, and the material of the optical lamp covers 15 is plastic.

The plastic optical lampshade can be a polymethyl methacrylate optical lampshade or a polycarbonate optical lampshade. The plastic optical lampshade has the advantages of being not fragile, high in processing efficiency, high in light transmittance and the like, and can well protect various structures inside the shell 11.

Optionally, the number of the optical lamp covers 15 is one, and the optical lamp covers are made of glass.

The glass optical lampshade has the advantages of high light transmittance, high temperature resistance and the like, and both the light transmittance and the temperature resistance are higher than those of the plastic optical lampshade. Simultaneously, glass optical lampshade has satisfied the demand of user to traditional lamp shade material.

Optionally, the number of the optical lamp covers 15 is two, the first optical lamp cover is made of plastic, the second optical lamp cover is made of glass, and the second optical lamp cover is located outside the first optical lamp cover.

After the light emitted by each light source 131 of the light source assembly 13 of this embodiment passes through the lens module 14 and the optical lampshade 15 through two optical designs, the light emitted finally is relatively uniform, that is, the light emitting effect of the lamp of this embodiment is relatively good.
